Mirror Telescope

When I'm looking at the inside of a mirror telescope:

I'm wondering why the secondary mirror does not block half of the incoming light? Is it "transparent" in this direction?

• Why in the world would you think it doesn't block incoming light? Dec 10 '16 at 17:18
• @CarlWitthoft My guess is that netik thinks there should be a "hole" in your image where the secondary mirror is. This is nothing more than a basic misunderstanding with how the optics of a telescope works. Dec 10 '16 at 18:49
• @zephyr you're probably right there. Shall we regal him w/ stories of Fourier Transforms? :-) Dec 11 '16 at 13:04
• yeah @Zephyr that's basically what I thought haha. Dec 11 '16 at 17:33
• Perfectly reasonable thought unless you really learn how optics works. Unfortunately, its fairly complicated stuff and there are entire textbooks just on optics. It looks like the answer you accepted didn't fully explain why there isn't a dark spot in your image. If you're still interested, I can try to provide a brief answer to explain that. Dec 11 '16 at 18:00

In a Newtonian reflector, as pictured, the secondary mirror does block some of the light, but maybe less than you think. Even if the secondary were half the diameter of the primary, it would only block 1/4 of the light ($\ (1/2)^2$). In a more typical case the secondary would be somewhat smaller - perhaps a quarter of the size of the primary (or less). Hence a $1/16th$ or less is blocked, which is not too bad.

# 6.8 Inference using compressive measurements  (Page 2/2)

 Page 2 / 2

In the case where the class of signals of interest corresponds to a low dimensional subspace, a truncated, simplified sparse approximation can be applied as a detection algorithm; this has been dubbed as IDEA  [link] . In simple terms, the algorithm will mark a detection when a large enough amount of energy from the measurements lies in the projected subspace. Since this problem does not require accurate estimation of the signal values, but rather whether it belongs in the subspace of interest or not, the number of measurements necessary is much smaller than that required for reconstruction, as shown in [link] .

## Classification

Similarly, random projections have long been used for a variety of classification and clustering problems. The Johnson-Lindenstrauss Lemma is often exploited in this setting to compute approximate nearest neighbors, which is naturally related to classification. The key result that randomprojections result in an isometric embedding allows us to generalize this work to several new classification algorithms and settings  [link] .

Classification can also be performed when more elaborate models are used for the different classes. Suppose the signal/image class of interest can be modeled as a low-dimensional manifold in the ambient space. In such case it can be shown that, even under random projections, certain geometric properties of the signal class are preserved up to a small distortion; for example, interpoint Euclidean ( ${\ell }_{2}$ ) distances are preserved  [link] . This enables the design of classification algorithms in the projected domain. One such algorithm is known as the smashed filter  [link] . As an example, under equal distribution among classes and a gaussian noise setting, the smashed filter is equivalent to building a nearest-neighbor (NN) classifier in the measurement domain. Further, it has been shown that for a $K-$ dimensional manifold, $M=O\left(KlogN\right)$ measurements are sufficient to perform reliable compressive classification. Thus, the number of measurements scales as the dimension of the signal class, as opposed to the sparsity of the individual signal. Some example results are shown in [link] (a).

## Estimation

Consider a signal $x\in {\mathbb{R}}^{N}$ , and suppose that we wish to estimate some function $f\left(x\right)$ but only observe the measurements $y=\Phi x$ , where $\Phi$ is again an $M×N$ matrix. The data streaming community has previously analyzed this problem for many common functions, such as linear functions, ${\ell }_{p}$ norms, and histograms. These estimates are often based on so-called sketches , which can be thought of as random projections.

As an example, in the case where $f$ is a linear function, one can show that the estimation error (relative to the norms of $x$ and $f$ ) can be bounded by a constant determined by $M$ . This result holds for a wide class of random matrices, and can be viewed as a straightforward consequence of the same concentration of measure inequality that has proven useful for CS and in proving the JL Lemma  [link] .

Parameter estimation can also be performed when the signal class is modeled as a low-dimensional manifold. Suppose an observed signal $x$ can be parameterized by a $K-$ dimensional parameter vector $\theta$ , where $K\ll N$ . Then, it can be shown that with 0 $\left(KlogN\right)$ measurements, the parameter vector can be obtained via multiscale manifold navigation in the compressed domain  [link] . Some example results are shown in [link] (b).

# B What is energy?

#### Avalon_18

While I was doing some practice questions it hit me "what is energy". I also don't understand how the formulas for potential and kinetic energy were derived. Was it due to their definitions or is there some reason behind their respective formulas.

Energy is a measure for work: if you do some work to move a book from the bottom shelf to the top shelf, the difference in potential energy of the book is the work you have done. Establishing a zero point for energy is awkward because in the real world all we have is energy differences.

An interesting question to which I do not know the answer! My recollection is that I first thought about energy when learning about Joule and work-heat equivalence. But maybe I'd met KE before and not thought much about it.

If you do have a concept of KE, then PE seems obvious. When an object falls, it gains speed and hence KE due to the acceleration caused by gravity. So when an object is high up, it has the potential to gain KE by falling. Or if an object has speed, KE, then it has the potential to rise up against gravity.

Quantitatively the change in KE with height when moving in a gravitational field works out at mgh, so that becomes the PE.

There are many videos online on the subject "what is energy?". Perhaps what they all have in common is that it is not, in general. easy to define. One simple approach is to leave it essentially undefined, but list the different forms it can take: kinetic, potential, chemical, thermal, nuclear, radiation.

There are several equally valid definitions used in different branches of physics. In Newtonian mechanics energy is defined as the capacity to do work. In thermodynamics an approach like @PeroK is used, energy is defined as kinetic energy ($\frac{1}{2}mv^2$) and anything that can be converted to kinetic energy. In Lagrangian mechanics it is defined as the conserved quantity associated with time translation symmetry of the Lagrangian.

No. KE and thermal energy of an ideal gas are motion. Thermal energy of other materials would have some of its energy in internal degrees of freedom corresponding to motion, but could also have non motion internal degrees of freedom if available. Most other forms of energy are not necessarily manifested as motion, although of course they can all be converted into KE. For example, electromagnetic energy can move (radiation) but you can also have static electromagnetic fields which hold energy without moving.

Does your textbook say anything about this stuff? It would help if we can use it as a starting point for discussion. Is this a grade-school or university textbook? The university level textbooks that I've used all make at least some attempt at this.

#### A.T.

A quantity that is conserved in an isolated system over time.

All the formulas for energy where defined such that the total energy is conserved in an isolated system over time.

#### BeedS

That is when work is being done, something is converted to KE. What work doesn't involve moving something?
For example, electromagnetic energy can move (radiation) but you can also have static electromagnetic fields which hold energy without moving.
No work is being done with the static field (PE), when work is done the field will move(KE) the charge or whatever is being moved/worked/energized?

#### Dale

Mentor
What work doesn't involve moving something?
None. $dW=F\cdot dx$

No work is being done with the static field
Sure, but it is still energy. The question was “do all forms of energy manifest as motion” not “do all forms of work manifest as motion”. Work and energy are closely related, but they are not the same thing.

#### BeedS

Sure, but it is still energy.
Yes in a stable configuration.
The question was “do all forms of energy manifest as motion” not “do all forms of work manifest as motion”. Work and energy are closely related, but they are not the same thing.
So all forms of work manifest as motion? Judging by your "None. dW=F⋅dx" reply, then yes?
And I need to look into my understanding of work and energy.
Thanks

IFRS Reconciliation Adjustments for Goldman Sachs Group Inc. (The) Depositary Shares each representing 1/1000th Interest in a Share of Floating Rate Non-Cumulative Preferred Stock Series A

1. When measuring hedge ineffectiveness, an entity shall consider the time value of money. Consequently, the entity determines the value of the hedged item on a present value basis and therefore the change in the value of the hedged item also includes the effect of the time value of money.
2. To calculate the change in the value of the hedged item for the purpose of measuring hedge ineffectiveness, an entity may use a derivative that would have terms that match the critical terms of the hedged item (this is commonly referred to as a 'hypothetical derivative'), and, for example for a hedge of a forecast transaction, would be calibrated using the hedged price (or rate) level. For example, if the hedge was for a two-sided risk at the current market level, the hypothetical derivative would represent a hypothetical forward contract that is calibrated to a value of nil at the time of designation of the hedging relationship. If the hedge was for example for a one-sided risk, the hypothetical derivative would represent the intrinsic value of a hypothetical option that at the time of designation of the hedging relationship is at the money if the hedged price level is the current market level, or out of the money if the hedged price level is above (or, for a hedge of a long position, below) the current market level. Using a hypothetical derivative is one possible way of calculating the change in the value of the hedged item. The hypothetical derivative replicates the hedged item and hence results in the same outcome as if that change in value was determined by a different approach. Hence, using a 'hypothetical derivative' is not a method in its own right but a mathematical expedient that can only be used to calculate the value of the hedged item. Consequently, a 'hypothetical derivative' cannot be used to include features in the value of the hedged item that only exist in the hedging instrument (but not in the hedged item). An example is debt denominated in a foreign currency (irrespective of whether it is fixed-rate or variable-rate debt). When using a hypothetical derivative to calculate the change in the value of such debt or the present value of the cumulative change in its cash flows, the hypothetical derivative cannot simply impute a charge for exchanging different currencies even though actual derivatives under which different currencies are exchanged might include such a charge (for example, cross-currency interest rate swaps).
3. It would not be acceptable to designate only some of the financial assets and financial liabilities giving rise to the inconsistency as at fair value through profit or loss if to do so would not eliminate or significantly reduce the inconsistency and would therefore not result in more relevant information. However, it would be acceptable to designate only some of a number of similar financial assets or similar financial liabilities if doing so achieves a significant reduction (and possibly a greater reduction than other allowable designations) in the inconsistency. For example, assume an entity has a number of similar financial liabilities that sum to CU100 and a number of similar financial assets that sum to CU50 but are measured on a different basis. The entity may significantly reduce the measurement inconsistency by designating at initial recognition all of the assets but only some of the liabilities (for example, individual liabilities with a combined total of CU45) as at fair value through profit or loss. However, because designation as at fair value through profit or loss can be applied only to the whole of a financial instrument, the entity in this example must designate one or more liabilities in their entirety. It could not designate either a component of a liability (eg changes in value attributable to only one risk, such as changes in a benchmark interest rate) or a proportion (ie percentage) of a liability.
4. An entity applies IAS 21 to financial assets and financial liabilities that are monetary items in accordance with IAS 21 and denominated in a foreign currency. IAS 21 requires any foreign exchange gains and losses on monetary assets and monetary liabilities to be recognised in profit or loss. An exception is a monetary item that is designated as a hedging instrument in a cash flow hedge (see paragraph 6.5.11), a hedge of a net investment (see paragraph 6.5.13) or a fair value hedge of an equity instrument for which an entity has elected to present changes in fair value in other comprehensive income in accordance with paragraph 5.7.5 (see paragraph 6.5.8).

*International Financial Reporting Standards (IFRS) adjustment process involves reviewing the company's financial statements and identifying any differences between the company's current accounting practices and the requirements of the IFRS. If there are any such differences, neural network makes adjustments to financial statements to bring them into compliance with the IFRS.

Abstract. We consider a nonlinear logistic equation of superdiffusive type driven by a nonhomogeneous differential operator and a Robin boundary condition. We prove a multiplicity result for positive solutions which is global with respect to the parameter $\lambda>0$ (bifurcation-type theorem). We also demonstrate the existence of a minimal positive solution $u_{\lambda}^{\ast}$ and determine the monotonicity and continuity properties of the minimal solution map $\lambda\rightarrow u_{\lambda}^{\ast}.$

Then the king will say to those at his right hand, ‘Come, you that are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food, I was thirsty and you gave me something to drink, I was a stranger and you welcomed me, I was naked and you gave me clothing, I was sick and you took care of me, I was in prison and you visited me.’ Then the righteous will answer him, ‘Lord, when was it that we saw you hungry and gave you food, or thirsty and gave you something to drink?  And when was it that we saw you a stranger and welcomed you, or naked and gave you clothing?  And when was it that we saw you sick or in prison and visited you?’  And the king will answer them, ‘Truly I tell you, just as you did it to one of the least of these who are members of my family, you did it to me.’

\eqalign{ \int_0^\infty {\sin^2 t\over t^2}\,dt&= {-\sin^2 t\over t}\biggl|_0^\infty + \int_0^\infty{ 2\sin t\cos t\over t}\,dt\cr &={-\sin^2 t\over t}\biggl|_0^\infty + \int_0^\infty{ 2 \sin 2t \over 2t}\,dt\cr &= 0 + \int_0^\infty {\sin u\over u}\,du }

# How do you write the equation y+3=3(x+5) in standard form?

Dec 27, 2017

The Standard Form of a Linear Equation is given by

$\textcolor{red}{A x + B y = C}$

Hence our Final Solution in Standard Form is

$\textcolor{b l u e}{- 3 x + y = 12}$

#### Explanation:

We are given the following equation:

$y + 3 = 3 \left(x + 5\right)$ Equation.1

Using Distributive Property we get,

$y + 3 = 3 x + 15$

Add $\textcolor{red}{\left(- 3\right)}$ to both sides to simplify:

$y \cancel{+ 3} + \textcolor{red}{\left(\cancel{- 3}\right)} = 3 x + 15 + \textcolor{red}{\left(- 3\right)}$

On simplification we get,

$y = 3 x + 15 + \textcolor{red}{- 3}$

$\Rightarrow y = 3 x + 12$ ... Equation.2

Note that we now have the equation in Slope-Intercept Form

Using basic algebraic concepts, we can obtain the equation in Standard Form

We want both the $x \mathmr{and} y$ terms on one side and the constant on the other side of our equation to write in Standard Firm

We will add $\textcolor{red}{\left(- 3 x\right)}$ to both sides of our Equation.2 to get

$y + \textcolor{red}{\left(- 3 x\right)} = 3 x + 12 + \textcolor{red}{\left(- 3 x\right)}$

$\Rightarrow y + \textcolor{red}{\left(- 3 x\right)} = \cancel{3 x} + 12 + \textcolor{red}{\cancel{- 3 x}}$

$\Rightarrow y - 3 x = 12$

Rewriting the equation to match $\textcolor{red}{A x + B y = C} ,$ which is the Standard Form we get

$\textcolor{b l u e}{- 3 x + y = 12}$

Hope this helps.

$3 x - y = - 12$

#### Explanation:

$\text{the equation of a line in "color(blue)"standard form}$ is.

$\textcolor{red}{\overline{\underline{| \textcolor{w h i t e}{\frac{2}{2}} \textcolor{b l a c k}{A x + B y = C} \textcolor{w h i t e}{\frac{2}{2}} |}}}$

$\text{where A is a positive integer and B, C are integers}$

$y + 3 = 3 x + 15$

$\text{rearrange into standard form}$

$\Rightarrow 3 x - y = - 12 \leftarrow \textcolor{red}{\text{in standard form}}$

The study basis is bad, a web based questionnaire run under no controlled conditions. Out of 25k respondents only 12k answered the income part, and they acknowledge that it was skewed towards young people, which was my first thought. Well off professionals are unlikely to respond to any questionnaire, because they know that time=money and they've got better uses for their time. So the results are bogus and basically say "young INTP's don't make a lot of money". Duh.

FWIW the last time I made 80k was not long after I got hired.

hey architect can i have some money i only have like $2.40 and the$2 coin is actually a priceless heirloom so i cannot spend it sorry. plzz architect i will repay you with funny forum posts totally worth it trade!!

This is why I like Socialism, it seems to fit my personality. Of course, that is assuming that I would always get a living wage and the ability to try as many jobs as possible. I am a very fast learner but rarely an expert, more of a jack of all trades, of course. That being said, my good is probably better than most so not really a bad thing. Now my memory, that needs some work. Not sure if it sucks or if I just don't care to retain most things.

It seems a bit silly but I believe the only reason I am where I am is because I have been very naive/oblivious against my type/feelings. I just went along with what came along and logically, made sense. I got married, had kids, went to college, got a good job. Seemed like the thing to do to provide for me and my family. Of course, if you read my other posts, you'd see I seem to struggle with that a bit but it has worked. For how long is another question.

I am starting to think of my type as very adaptive. However, that is a reactive trait, not a proactive trait. Having the ability doesn't do you any good unless you are satisfied doing it. I feel like i'd be happy to get paid and promoted to fill any duties necessary but not stay in the duty because that bores the shit out of me.

Applying yourself < being lazy researching something outside of your expertise. That is my motto.

Well, ENTPs are the guys who throw stuff out from their heads for others for free. I'm fine with it.

Bunch of TJs with same education makes much more money than me. In fact I'm studying even more university courses never intending to profit from them.

Yes!
I need hymn for laziness.
Maybe I should study music theory.

xNTPs and their poor social skills might be the answer. Like I should go out and kiss people's asses and after that wipe them. That is not comfortable and I'm ideologically against networking.

#### gilliatt

Well 30-40k$/year is about average master's level education pay check. Not wise to go much higher maybe 50 k$/year. (well you get education, health care, day care and other shit without paying extra. It is even wiser to stay unemployed than do 10-15k$/year job.) #### Tannhauser ##### angry insecure male Most moneymaking out there is happening via "talk big, play small". That happens to be what INTPs are bad at. #### Sinny91 ##### Banned I've done every single damn thing wrong since I left school. Didn't help that my parents practically ruined my life at every opportunity they got. Far from fucking helped. When ever I have been in "decent" paying jobs the majority of my money went on rent and bills. I got sick of that so quit trying to be "proper". I so should have just lived with somebody else on the cheap. Now I'm turning 25 with absolutely ZERO to show for it. But I'm trying to count my blessings rather than burdens. I've still got time to turn it around, right? I hope. Gulp. WW3 not starting yet? I'm pretty sure my ideal job role is leader of the free world. #### bvanevery ##### Redshirt who doesn't die Now I'm turning 25 with absolutely ZERO to show for it. I didn't even enter the professional workforce until I was 26. It was an artifact of my weird history of mostly self-education in computer science. I entered during the dot.com boom and made some money just fine from 1996 to 1998. Then as per the times, I quit to find my own star as a game developer. I neglected to make any money while I was at it and got into a lot of credit card debt. The dot.com bust happened and I went down the tubes. I did the survival job of signature gathering for awhile, to keep a roof over my head. It was probably the best low end survival job I was going to get. Doesn't mean it had any realistic future for me. After 4 years of that it got old. I retreated to NC under my Mom's roof for a time and tried to regroup. I got a brief gig that paid well with Mozilla. I got paid but I blew the contract, I didn't deliver the result I had pitched. I also hated doing the kind of work I was doing. It was a "scaled up" version of stuff I'd done for free in open source land, but the scaling to a massive body of code drove me nuts. It pretty much ended my so-called career as a buildmaster. I had gotten good at something that I really shouldn't, that's a dead end. Hateful horrible work. That takes me to age 37. I lived off the Mozilla proceeds for a couple years, as I did get paid pretty well for that one gig. But eventually it ran out. I wrestled with my misgivings about the computer industry, and I'm still wrestling, I haven't found any solution. I started living out of my car because I needed an escape route from this boring horrible existence of being a tech slave for no purpose. The purpose has to be on my terms, otherwise there is no value in it. Now I'm 46. I haven't given up on computer stuff, but man, it's amazing how the years drag on. I can definitely say I'm competent at living out of a car, including repairing it. There's a bit of a learning curve for both of those. I couldn't have kept this up if I hadn't learned that skill. I do find that the car thing is getting old, as it prevents me from getting certain other social things done in my life. For instance, I have to leave town during the winter. I had a friend of mine who hemmed and hawed about college degree stuff vs. world travel for years and years. He finally did go back to school and take some classes in something belatedly, way into his "adulthood". I don't know if it helped him economically or psychologically. Our friendship soured over the years, with different attitudes about how one should deal with adversity. I firmly believe in denying oneself basic luxuries in order to make ends meet. Like, if you can't afford coffee, stop drinking coffee. Don't beg your friends for money to buy coffee, that's not something you should be asking others for. Have some fucking self-discipline about that sort of thing, the world doesn't owe you coffee. Arguably an industrial society does owe you food, which is why I take food stamps, but coffee is a luxury and bad for you anyways. I think all one can really do, is try to decide on a path, then set oneself on the difficult road of trying to follow it. In the real world there will be many disruptions and distractions. You will get lost. Eventually you will realize you are lost. When you realize that, then you need to put your focus and concentration into getting back on track again. Beating yourself up about the fact that you get lost is pointless. Shit happens, you will get lost. The fully loaded cost of accomplishing anything, especially things that are nebulous and not cut and dried "widget" activities, is enormous. It is best to seek what we are most suited to withstand, by temperament. For instance, I'm not going to put up with some fucking boss telling me what to do, at this point in my life. Nor did I particularly care for it at any earlier point in my life. So it's up to me to figure out a viable self-employment model. Signature gathering did work in that respect, that's what I liked about it, but it was a boring complete misuse of my intellect and not sustainable. Signature gathering favors people who love other people and like to sway crowds, and that's not me. I just did what I needed to do by brute force, with no particular guile or art, because I had to, to survive. My temperament is suited to living out of a car, and to fixing it, so I do it. I don't always like it, especially when the car breaks down, that pretty much sucks. But my temperament can handle it, better than some other fires or frying pans I might jump into. #### Sinny91 ##### Banned Yea... I get that.. I've got some credits towards my degree, but made the mistake of going into work rather than full time Uni. I wish I could go back and just do what everybody else done... But the reason I didn't do that at the time is because my mom made it nigh impossible for me. Dunno what the future holds in regards to work for me. I'm only skilled in the office and behind a bar. I fucking hate office work, and bar work isn't exactly a lifetime career. My cousin is opening a bar and wants me to work there.... But still, can't be a permanent thing, makes me drink a lot too. My only passion is in politics, but being the commoner that I am, I won't be moving up those ranks any time soon. I dunno whether to stay at 'home' and prioritise my degree in International Development, or whether to look for some opportunities abroad. The latter sounds more fun. But if I don't accomplish something 'status worthy' by the time I reach thirty I think I'll truly hate myself. #### smithcommajohn ##### Do not consume with alcohol Yea... I get that..

You have a lot of pent up energy. You need an outlet for that where you can make money. Somehow I picture you being really good at starting a YouTube Conspiracy Channel where you discuss the validity of all the various conspiracy videos out there in internet land. I dunno how many views you need to start making ad revenue, but maybe worth looking into? #### bvanevery ##### Redshirt who doesn't die But if I don't accomplish something 'status worthy' by the time I reach thirty I think I'll truly hate myself. There are many goals that one can impose upon oneself, and many psychological consequences when one doesn't live up to one's own expectations. Myself, I think of myself as some kind of R&D guy, whether in games, programming, or art. I have extremely lofty ideas about what I think I'm trying to do. If I wasn't working on the most difficult problems I could personally contemplate, I think I would be misusing my intellect. Safer, easier, more conservative and materially productive paths are not for me. I have this high risk, high reward idea of how I'm living my life. And the reward, needn't be financial. I hope that I will come up with something that is either great art, or great benefit to normal people, or great benefit to techies pursuing the kinds of struggles I've been pursuing. I am deliberately swimming against the current. So if at times it seems to be drowning me, I can accept that it's by my choice, no one else's. It is possible that I will flounder around and not get any of these lofty things done. But I haven't yet seen a reason to give up on myself. Rather, I have recognized the fundamental tedium of the world for what it is. I've said before, life is like this gigantic fractal maze. It has ever expanding surface area, like a mitochondria. You get to wander around in your own personal search space in this gigantic never ending maze for awhile. Then you die. The measure of my life, is how far I got through that maze while I was here. I think I may yet get farther, make more connections, cause more things to happen, than I have seen happen so far. At least what I have gained so far, is an understanding of how reality works, and I have shared and left kindness and love with some other beings along the way. The simple love of a cat or a dog, can mean a lot. I have saved 2 creatures from bad fates, that got to experience love and a good life, rather than some grim fate while they were here. I wish I could have saved the 3rd, but Louise's problem was beyond my understanding and imagination at the time. So... be careful what goals you impose on yourself, for "what is supposed to happen" by the time you're 30. Nobody really has a spreadsheet to determine what your life will be at 30. Not even you. If you had told my previous self 10 years ago where I'd be now, I would not have believed it. I could not have imagined that anything would have taken as long to unfold as it did. Do ponder yourself, your existence, and set some goals of where you think you want to go. Be willing to evaluate where you are, compared to where you thought you wanted to be, or expected to be. Oh heh if the Apocalypse comes in some form or another, I'm much better equipped to survive than lots of people in society. That time in the woods and otherwise "roughing it" will come in handy. Especially psychologically. It's almost a pity to have developed such skills, only to return to a cushy money driven civilization where they're not needed so much. But at least I've learned how to keep my mind mostly together. #### Sinny91 ##### Banned You seem so vulnerable at times, it reminds me you're human, Sinny. Me? Human? Pffftttt. Aha.

Possibly, I do love a good 'ol conspiracy theory! #### bvanevery ##### Redshirt who doesn't die Possibly, I do love a good 'ol conspiracy theory! Is there actually any money in that anywhere? I have an inherent bias that I'm on the exact opposite side of this spectrum. I'm a scientific Skeptic and do not like conspiracy theories at all. I'm a member of the Asheville Skeptics. Every week, we spend time running our mouths about how to deal with conspiracy theories and the people who believe in them. The harms to society, what are we going to do about it, yadda yadda. Sometimes I wonder if we even have a purpose, as I think our political impact is close to zero. However we do manage to have a local community of rationally minded people, who aren't driven by guff, and are reasonably skilled at understanding and disseminating how guff works. Recently we've embarked on a semi-formal lecture format once a month. We take turns making presentations on whatever. 2 months ago I did one on a book criticizing religion. I wanted to do something more ambitious than a book report, but I found that was more time consuming than what I was willing to put in. The main monetization I've noticed for conspiracy theory bullshit, is that crap on The History Channel about Ancient Astronaut Theory. I hate that shit! They're total fucking slimebags, they just say whatever without usually presenting any scientific or factual side of things at all. It's usually wild speculation couched in the language "is it possible that...?" "could it be that..?" because that way they never have to commit to bursting anyone's conspiracy theory bubble. Let the entertainment bullshit continue, they don't actually do so much history on the history channel anymore. Not enough money in people who want to know about the Third Reich or Roman legions or stomping on indigenous people or whatever. Just make some Ancient Astronaut Theory bullshit to get everyone all riled up, then watch the bucks roll in! So who knows, maybe if you actually believe that crap, there's some production company in the UK that can take you on as their committed flunkie. Not every fakeo-documentary has been completely imbalanced on The History Channel, but most of them have. To the point that when I'm channel surfing and I see one of those things, I generally just scream and move on. Why do I hate this stuff so much? Because it's people who can't figure out how people actually figured things out. The rest of us who have a brain for engineering and science, whose ancestors actually fucking made atlatls and slid big stones over wetted sand in Egypt, we have to put up with these shitheads who are too stupid to figure out how stones can be moved around. They don't fucking have a clue, so they think there's some big mystery and Da Fuckin Aliens Musta Dunnit! LAAAAAME. The Egyptians even did us the fucking favor of painting how they did this stuff on walls, so that we could know how clever they were, how they lived. And people just ignored it for a couple of centuries as mere ceremony! People are fucking morons.

When The Discovery Channel tries to do something sensationalist, they don't lie to you about it. They posit a "what if?" like what if we completely drained the oceans, what would the bottom of the ocean look like? So it engages the imagination, it's creative, but it's not lying to you about the science. Same with their series about "what if all the humans completely disappeared? what would happen to all the cities and infrastructure?" Watching skyscrapers turn into jungles is pretty cool. #### Sinny91 ##### Banned No actually, I'm far more interested who funds the contracts/projects for the History Channel and the like. More often than not they have dodgy and sometimes high level sponsors. (Robert Bigelow, just to name one) So hush with your 'elitist skeptic' bollox. But with the kindest regards. I have James Carrion on my facebook who was the International Director of MUFON, who had worked a lot with the History Channel/Nat Geo, et al up until he started blowing the whistle on the contract frauds and disinformation plaguing the sector. (Which is obvious to anyone with half a brain cell) And yes, there's lots of money to be made in that field - but not for seekers of truth, unfortunately. Like, where 'Skeptics' like you go wrong is lumping all conspiracy theories together. The world is plagued by real conspiracies, that's a fact. The ancient astronaut theory has some validity, if you actually start delving into human history. But that would actually mean cross referencing shit, and just who can be bothered to do that?! And dude, use a spoiler?? #### bvanevery ##### Redshirt who doesn't die Oh you mean for the giant picture? I think I'd rather just find a smaller version. So often, seeing is believing. Well that was a PITA, guess I have to settle for a small amount of seeing being a small amount of believing. Better luck next time. Hm, well, managed to point at the original and resize it for display. But that link could go stale, so I'll leave the local attachment as well. #### bvanevery ##### Redshirt who doesn't die Like, where 'Skeptics' like you go wrong is lumping all conspiracy theories together. The world is plagued by real conspiracies, that's a fact. There aren't so many. The ones that actually are, tend to be things like terrorism or organized crime. Sometimes political machines. There have been some verified false flags. But the Big Humongous Controlling Secrets stuff, like the 9/11 Truther movement, is bollocks. You can't keep secrets like that from so many people, the command and control for it is impossible. 9/11 Trutherism is a simple inability to understand that military tactics have always progressed. Those 'towelheads' figured out a good one and gave the USA a really good bloody nose. I use that term to indicate that a lot of people in the USA are too bigoted to ascribe the necessary intelligence to their enemy. Partly because they're smarter than a lot of Americans, who just can't seem to wrap their head around creative ways of inflicting mayhem on another nation. Boy aren't they lucky that most of us who can creatively think like that, are on the side of Good [TM], and would sooner do the forensic analysis / criminology of figuring the Bad Guys [TM] out, than doing all the stuff we could think of doing. Plus, you run out of highly trained teams of people who are going to commit suicide for you. Much easier to inspire people who are already suicidal to pick up an AR-15 and start shooting. It bears repeating, that the collapse of the World Trade Center towers is a unique engineering event in the history of humanity. No skyscraper has ever been bombed, before or since. [*] WW II was the last opportunity for seriously bombing the crap out of big buildings, and Europe didn't build any skyscrapers in that era. It was an American thing, and we had big oceans to keep anyone from reaching us. We managed to run some of our own small planes into them and do some damage, but nothing with the fuel load of a jumbo jet. Yet so many people armchair this unique engineering event, like they know how things were "supposed to" happen, and things "can't be" the way the authorities decided they actually were. They can't understand really basic stuff like steel only needing to fatigue under heat stress, not actually melt, in order to lose structural integrity and have the whole thing come crashing down. They find thermite samples where none existed. They can't accept things like falling debris actually knocking the shit out of WTC7. They're a bunch of fucking morons. You can show people all kinds of video and forensic evidence and they're still too stupid to get it. [*] That mattered. Al Qaeda did try to blow up WTC before, from the ground floor. The ancient astronaut theory has some validity, if you actually start delving into human history. But that would actually mean cross referencing shit, and just who can be bothered to do that?! It doesn't have any validity. It flies in the face of archaeological evidence of all the stuff human beings actually invented. It's basically a secularization of the whole "God waved his magic hand and POOF we started getting things done" idea. What actually happened is we evolved intelligence and problem solving, starting with very basic things like carrying rocks and hurling them when we started standing more upright. You hurl things long enough, you get atlatls. But if you don't understand the systemic consequences of evolution, if you're incapable of thinking in those terms, you invent 'aliens' to do all the work for humanity. Then you're still left with the question of how the aliens figured out all their crap. It's the same answer, they had to evolve their solutions, same as anything alive anywhere. So why not humans? Especially since there's no evidence of alien visitations at all. Don't get me started on people too stupid to understand carbon dating. Are all the children's science museums really doing that bad a job, that kids aren't getting this shit, when they're young enough to just absorb how things work instead of getting clouded by political mumbo jumbo? I do know that some of the religious types, have had abysmal scientific educations as kids. I don't know how widespread that problem is, but it's definitely anecdotally true of a number of my peers in the Western NC Humanists. Things like that do actually happen in the Bible Belt, they're capable of breeding morons. Some of them eventually manage to pull away from it. Some even have huge dramas with their parents, when they're smart enough to figure out evolution on their own, and their parents aren't. Big stress when that happens. But this can't be the whole story. I always liked science / natural history museums just fine, and we had good ones in San Francisco. Even modest sized towns have science museums, like Winston-Salem NC, or even tiny Hickory NC down the road from us. What's wrong with people that they don't learn the basics? Or maybe they learn them by rote, and don't know what to do with them? I just don't know. I think I'll bring this up at the next Skeptics meeting. #### Sinny91 ##### Banned I have an inherent bias that I'm on the exact opposite side of this spectrum.

I wouldn't waste your time on who believes in them, I'd spend more time looking at who peddles them. From my experience there are 4 kind of conspiracy theorists: 1) Idiots who will and want to believe in anything 2) Enemies of that state 3) Disinformers of the state and/or private interests. 4) Truth seekers caught up in a web of lies..

What actually happened is we evolved intelligence and problem solving, starting with very basic things like carrying rocks and hurling them when we started standing more upright. You hurl things long enough, you get atlatls. But if you don't understand the systemic consequences of evolution, if you're incapable of thinking in those terms, you invent 'aliens' to do all the work for humanity. Then you're still left with the question of how the aliens figured out all their crap. It's the same answer, they had to evolve their solutions, same as anything alive anywhere. So why not humans? Especially since there's no evidence of alien visitations at all. Don't get me started on people too stupid to understand carbon dating. #### bvanevery ##### Redshirt who doesn't die So what are yous going to do about it? lol At present, I am primarily concerned with small scale community formation and sustainability. Rational, skeptical inquiry into the phenomena of the world, has to be an interesting, sustainable interest for a sufficient number of people in a city like Asheville. Otherwise the concept dies, as not being terribly relevant to people's lives. Then when some Big Lie comes your way, like Trump's bullshit about thousands of Muslims cheering in the streets when the towers fell, or something inane from a local Church, or the next miracle diet that's gonna melt fat away, people lack the media literacy to deconstruct and critique it. Rational inquiry needs to be a promoted cultural practice, and people need to practice using their intellectual tools in non-destructive ways. Got a website or any resources I can check out? To be honest I'm poorly versed in the Skeptic movement as it exists online. I'm still going up a learning curve about that. I basically found this group of Skeptics in Asheville, then applied my sociocultural anthropology background to a lot of what they were talking about. There was a lot of overlap between what I already knew and understood, and what they were on about. If I had a critique of some aspects of Skepticism, I would say some of them spend way too much time trying to play scientific games of "whack a mole", constructing proofs about God or 9/11 Truther details or Pearl Harbor details or whatever. Going after what you can pin down as factual is all very fine and well, but what actually drives the conspiracy theorists are their psychology and belief systems. To be glib, "not enough liberal arts and social science" in Skeptical thought at times. That's ok, I can do my part to correct it, as do others of my peers who have backgrounds in things like cognitive science. So I wouldn't tell you to go to some website. I'd tell you to go pick up texts used in a sociocultural anthropology class. Wanna know why people believe shit? Wanna know how it works everywhere, all over the world? Study all the world cultures, and find out what the ethnographers have been telling us for awhile, about what people actually believe. The patterns are overwhelming, even if the kind of data they present isn't as "hard science" as the physicists would like. Not all of experience comes in a chemistry flask. What was the conspiracy slant on that? The religious book, actually nothing. Skepticism encompasses more than just going after conspiracy theories. Religious baloney is also topical, like Creationism for instance. Or the anti-gay "they're choosing to be that way" stuff. One of our presenters did a big thing on epigenetics recently, which is probably the biological basis of people being gay. There isn't a "gay gene", but there is a mechanism which turns the expression of one's sexual traits on or off. There's more to understand than just "genes", it's slightly beyond what most of us learned back in high school biology class, but not that much more. Get your genes washed by the right chemicals, they 'methylate' and turn off. It's on TV isn't it, what did you expect? Not all TV is equally bad. It depends on the educational responsibility level of the network. "National Geographic" isn't going to sell out their integrity to get some more viewers for instance. Like you'd get the truth on those subjects anyway. Hey a ballista or onager is truth. I thought we all had the same ancestors? I'm not sure how the genes for intelligence have propagated through the generations, but it's pretty clear to me that lots of people didn't get 'em! But, whilst you're on the subject of moving stones.. I'm pretty sure there are a few mysteries and enigmas surrounding some monolithic structures. I'd will deffo get back to you with some examples that you can try and explain for me. There's this guy on YouTube who moves multi-ton blocks with simple wooden levers and pivots. It's not fucking rocket science, he did this stuff in his backyard. The reason people think it's oh so fucking mysterious, is they haven't been investing their social and life energy into moving big stones around, the way our motivated ancestors did. You think you've got some gods to please, seems you figure out how to do stuff. #### bvanevery ##### Redshirt who doesn't die LOL, as an ardent 911 Truther, I completely disagree. I pity you. I don't expect a debate, and don't really want one since I had a batshit crazy 9/11 Truther / alien conspiracy friend and eventually the friendship ended. I don't know why you personally believe this stuff, and he isn't necessarily a model for anyone else's reasons for believing it. But on the off chance there's an overlap, here's some food for thought... Do you really have a grasp of world military history? Really? Do you understand political history, especially of the Middle East, and why Al Qaeda wants to kill Americans? Do you know what peer reviewed literature is, and what a vanity press is? Are you aware of the psychological phenomenon of "externalizing the locus of control" ? This friend of mine pretty much sucked / was completely clueless in all these depts. He didn't know anything about the Middle East or our history in Soviet Afghanistan. He thought Osama bin Laden was a paid actor for the CIA and that Al Qaeda doesn't even exist. His grasp of physics and engineering was absolutely terrible. He'd look at some video and think he could just "eyeball" whatever he wanted to think about what was going on, that he didn't have to know anything about structural engineering or simulation at all! He couldn't tell what a bullshit paper that's never been through a peer review process was. He had deep emotional baggage about his family, and was using all this conspiracy theory stuff as a way to psychologically externalize and joust at the demons of his life. When the Big Conspiracy is exposed, the endgame is everyone's gonna get their control back. As long as the Big Conspiracy exists, no one can have control. His alien stuff was just as bad. He'd look at pictures of D-grade homemade special effects, the kinds of stuff from movies in the 1950s that people laugh at, and take them totally seriously. Any plausible explanation of, dude, here's how you could film this yourself, put a wooden stick behind this 'flying' saucer (that looks like a garbage can lid with steel balls welded on it) and it will appear to be floating in the picture frame... he'd insist it was all real. You did already enumerate this kind of guy, 1) Idiots who will and want to believe in anything. He's a real case. I tried to be a good friend to him. We got to the point where we had sparred / blown out about these subjects enough, that I was willing to just leave them alone. We had other things to be friends about. But my attitudes made him feel inferior, so he kept finding petty ways to try to attack me about other things. Eventually I had to tell him to knock it off a few too many times, so we had to part ways. Life lesson is you can't be friends with someone who's ego is too fragile. They will take it out destructively on you, as you become more and more of a threat to them. I don't tolerate dysfunctional bullshit like that, people like that have to walk. I can wish them the best as we part ways, and genuinely hope they find their way in the world, but I'm not going to spend the energy on them. They just try to suck you dry like a vampire with their own problems, trying to get you to participate in and legitimize their crazy. Can't do that for anyone, don't even remotely believe in doing that. You're just contributing to their own self-destruction in that case. #### Sinny91 ##### Banned Sorry, I thought you were a computer programmer (game designer/code person/whatevs), not a know it all. From a preliminary reading of what you just wrote it sounds like you cling to your own beliefs quite thoroughly, based on not much more expertise than any other common layman.. and you delude yourself into thinking you're in some sort of superior position and have it all 'sussed out' . You're getting on a bit now, so you may not live to see the disclosures of the official secrets acts. But I might. And me and my opinions will be vindicated, not all - probably. But 9.11 certainly. #### bvanevery ##### Redshirt who doesn't die I am a computer programmer, artist, martial artist, forestry / car dwelling guy with a survival streak, got that sociocultural anthropology background, have even more hats I've worn that I'm not mentioning, have always tested in the 99.999% of whatever those standardized tests were, graduated from a tough Ivy League school a long time ago, have debated people on the internet for 20 years, and am 21 years older than you are. You might want to consider whether some people have knowledge and experience that you don't, before claiming that they're 'clinging' to anything. I didn't "weigh in" on conspiracy theory stuff for a long time, since many other people said it was your bent, and I've had experience with at least 1 person's reaction to such things. But if after all I've posted on INTPforum you don't think what I have to say has any credibility or weight, then there's really no helping you. I would conclude that trying to establish a congenial virtual relationship with someone, doesn't count the minute it threatens core beliefs. You're just too young and will have to learn the world for yourself, anew, as every generation must. At least you're not taking the typical 25 year old male bullshit way of receiving 'advice' from your elders, which is typically to repeat "fuck you fuck you fuck you" loudly and clearly and peevishly over and over again with your fingers in your ears. ;-) So who knows you may figure some things out sometime. Actually I was never one of those, so I don't have much sympathy or patience for those. I did have to tell off "the older voices of reason" when I was younger, as all young people pretty much have to, to form their own identities and figure out their own way in the world. Anyways good luck with all of that. What you believe about the world, strongly conditions what the world is for you. And thus what is going to happen next for you, absent any change of insight. When someone beckons to some other door, some other way of looking at the world, it is sometimes worthwhile to consider why you are so strongly invested in your current world view. You may find it's fine, there's no problem, you don't need any new input to move on with life. You may find you're hiding lots of things from yourself and you need these scaffolds of emotional identity, lest your whole world collapse around you and make no sense at all. I've been tested in that way quite a bit longer than you have. So, hope you heed some small part of it, but you will do what you do. #### Sinny91 ##### Banned Yea, I appreciate you're older and have trodden more paths than me, but you have genuinely lost all credibility in my eyes, almost solely based on this 911 issue. The 911 Commission 'report', and NIST 'report' are the biggest conspiracy theories in print to EVER to grace modern history. lol But lets agree to disagree. Until the next time. #### intp_xp ##### Member There are many goals that one can impose upon oneself, and many psychological consequences when one doesn't live up to one's own expectations. So... be careful what goals you impose on yourself, for "what is supposed to happen" by the time you're 30. Nobody really has a spreadsheet to determine what your life will be at 30. Not even you. If you had told my previous self 10 years ago where I'd be now, I would not have believed it. I could not have imagined that anything would have taken as long to unfold as it did. Do ponder yourself, your existence, and set some goals of where you think you want to go. Be willing to evaluate where you are, compared to where you thought you wanted to be, or expected to be. This is good advice but I'd enforce that you should not fear not achieving them. That will just be another opportunity to evaluate what went wrong and how to do better next time. If you always set yourself up with an out then there really wasn't a goal worth striving for in the first place. Really, you may just be enforcing negative coping strategies. As for goals, you need to set short, mid and long term goals. If you only set short term goals, you may forever wander without a real purpose. If you only set long term goals, you may struggle with your present purpose. My current long term plan is to retire at 55 or earlier and I am currently on target to achieve that. I am struggling with short and mid term goals at the moment since 55 is still 19 years away. I want to better myself in other fields but have yet to find another position I think I can be happy in. Hobbies have kept me somewhat preoccupied short term but I struggle with their future purpose and cost. That and I am more of a solo hobbyist so it limits me a bit. I'd really like to put in some offline effort and get paid but I am pretty good at being lazy when I am not forced to accomplish anything. #### bvanevery ##### Redshirt who doesn't die This is good advice but I'd enforce that you should not fear not achieving them. That will just be another opportunity to evaluate what went wrong and how to do better next time. If you always set yourself up with an out then there really wasn't a goal worth striving for in the first place. Really, you may just be enforcing negative coping strategies. Over the long haul of a couple decades, I can assure you that chalking up yet another failure to "your learning curve" gets seriously old. It's all very fine and well to flounder when you feel like, in hindsight, you didn't really know all that much, and really didn't have all that much time put into it. Like a couple years, are you a God at something in only a couple of years? But if one manages to continue with patterns of failure for decades, in subject areas you claim to have expertise and focus in, it can really rattle you. You can find yourself standing back and saying, "WTF is my problem??" I do think people need to try and fail at things, that that's normal, and to be expected. But there comes a point at which you've put a lot of effort into something, and performance does matter. When assessing WTF has been going wrong over a really long time, there are a number of conclusions you might arrive at. One may be that the problems you set yourself to work on, were a few orders of magnitude harder than you thought. So, do you still think it's important to work on them? Some of those kinds of things, I'm not ready to give up on yet, I'm gonna keep going. But ask me again when I turn 50 how I feel about this shit. Hope I've had "the breakthrough" by then, otherwise it may be time to hang it up and do something else with my life. Another conclusion may be you're not actually very good at something, and you've been unwilling or unable to apply yourself in a way that would bring any significant improvement. You may end up having to say you are what you are and it is what it is. That wasn't too difficult for me regarding signature gathering for instance. 4 years of that, and my lack of talent and drive at it was clear enough. I was only good at the parts that weren't actually worth much money, like standing up to security guards, and making signs. It wasn't the core of the job, and I kept on trying to do things I liked better than the actual job. So I quit, and frankly I'm never going to gather signatures for money again. I might do it volunteer if something really really important came up, but for heavy lifting on that, I'd just as soon see the pros get paid to do it right. A third conclusion may be you simply don't have time to do it all. Not enough hours in the day, or years in your life. You might have to make some hard choices about what you will and won't apply yourself to. So, uh, yeah, if you're young and your "big plan" doesn't work out in 2 years, don't wallow in self-pity and despair and think you can never amount to anything. 2 years isn't a very long time. But don't get yourself in this mindset that your job is to fail indefinitely either. Performance does matter and it does erode your self-esteem when you consistently fail year after year after year after year. Actually I think what holds me up, since my indie solo game development career is pretty much a wreck, is that I've gotten some other things done in my life meanwhile. So I'm not a total failure, I've just been consistently failing in the one area that I claim is most important for me to succeed in. I can fix cars, I'm actually skilled at that. I can even fix them to some extent under real world survival pressure conditions, like "the fucking thing has broken down and I'm stuck here". I've gotten out of a few of those now. That situation sucks, but there's less fear each time, because I have a track record of prevailing. I can repair computers in my sleep, but who cares. Fucking computer industry, I hate them. Shitheads. I've painted a few decent things, although my art side is in a tailspin because I don't currently see much value in the images that come to my mind. That might change, but anxiety over needing to make progress on game stuff, tends to rob me of creative energy. That's a balancing issue really. Computers have been sucking the life out of my artistic energies for a very long time. Then when art itself sucks the life out of my artistic energies, it can take many months to recover from that. I've done a decent job raising my dog. I can be proud of that. One less dog in the world that would have suffered a horrible fate, had I not rescued him. I've also twice saved my Mom's cat from bad fates. So I've got like these animal rescue merit badges. I do have a viable social life in Asheville, it's just not complete. Basically, no dates. But I get plenty of intellectual stimulation and people like me well enough. Kinda sucks having to leave for Florida in the winter though. The survival stuff, living out of my car, is no big deal now. It's pretty much second nature. It's actually a skill to live this way. This becomes more apparent when one meets someone who's recently become homeless, and one sees how freaked out and impractical they are about living out of their car or whatever. Plus I can do a fair amount of forestry stuff, although I don't do so much of that anymore. That said, I think I'm throwing the camp stove in the car and running off to the woods a bit this fall, before the season is over. My current long term plan is to retire at 55 or earlier and I am currently on target to achieve that. Thankfully I'm in a field where I have no reason to believe in retirement. I can program until I'm dead. Or paint, if that goes somewhere someday. My 'plan' is someday I'll just make a huge pile of money somehow, on some game or something. Won't need all that long term savings crap. Only thing that will stop me in that regard is some kind of apocalypse, and I can handle that too! #### intp_xp ##### Member I was just using a quick word (retirement) that meant the same but ideally, it's a plan to stop being forced to work. Not that I want to work when not being forced but if I have the inclination to set myself towards a goal, whether work or other pursuit, I don't want to be constrained. I still have a wife and family to care for so I do have a bit more constraints than some others may have. It's my own fault really and just took me too long to realize I was going down a path I may not be able to sustain. I am very curious as to what the outcome will be. I am usually an optimist but I am not going to say anyone can do anything they put their mind to. Personality is part of the equation but not all of it. I am sure there are plenty of XXXX's that may be smart and some that may be stupid, some that have good physical attributes and some that don't. It may hurt some personalities more than others to be stupid while the same may be said for being smart. However, there is probably something out there that is a good fit. The struggle is trying to find what will fit while still trying to live life and be happy about it. High school and college don't necessarily lead you to find what fits. It gives you general knowledge of stuff and then you are forced to choose what seems the most interesting and you hope you get it right the first time. College/life debt can add up fast. There has got to be a better way. Of course, it all comes down to what you want out of life whether homeless, living in a car (or a van down by the river), on$30K a year or more.

The last few paragraphs in this link is what I have been trying to find and research lately. It didn't do me any good until I really understood who I was, not that I entirely do but more so than ever.

Regarding "falsification of type", I had a friend of mine who thought he suffered from it as a young man. He got his 1st job at Microsoft during the dot.com bust, and had a lot of fear about his ability to hold the job. Very opposite my own experience coming in during the dot.com boom, when programmers were all treated like royalty and we assumed we'd inevitably own the whole world.

Anyways, he saw a lot of type behavior at MS that he thought he had to emulate in order to get ahead, or even just stay afloat. Probably E*TJ stuff, and I think he's INFP. Plus MS had an internal management culture at the time, where the top 10% of any given work group WILL be promoted, and the bottom 10% WILL be handed a pink slip. Didn't matter if everyone on the team was absolutely stellar, or absolutely abysmal, so this led to some serious corporate dysfunction and cutthroat behavior between employees. Pretty much every man for himself on a sinking ship!

My friend didn't have the basic ego armor of knowing that "if things are SNAFU, it's usually because other people are idiots." That is to say, I'm immune to groupthink. I know other people are systemically stupid, and it's usually driven by a few key individuals who are stupid. My friend thought there was something wrong with himself. He had to struggle in college with his finances, and the Cornell CS dept. treated him like shit, so those were yet more reasons that he felt inadequate.

He finally figured out he was having a really serious "falsification of type" problem. So I asked him: if you stop caring today, how long is it going to take before they fire you? He ruminated for a minute, then said "six months". I said, "Ok, that's how long you have to look for a new job." He did. He jumped ship for Google, which eventually got old as well, but for different reasons and his personal psychology was a lot better there.

1. We live in the "Information Age", where information and ideas are the most valuable commodity.

2. \$30k is a very low salary in the US. Even waiters in busy restaurants make significantly more than that.

In short, if you are living right on the verge of poverty, it's not because you're INTP. It's because you're lazy and have tons of self-defeating beliefs that are neither exclusive nor inherent to your psychological type.

I dunno, I've been shocked by the number of blue collar people in Asheville working for low wages, and getting excited about "raises" that are still trivial amounts of money AFAIAC. Not all regions have a lot of jobs. Wages get repressed and a fair number of people, due to their education and possibly intelligence level, seem to just take what's offered. It does beg some questions about why people stick it out in a depressed economic region. Getting women pregnant and having to support a family could explain some of it. Otherwise, culturally maybe some of these people aren't very adventurous and don't have an inclination to travel in them. Maybe they don't have enough imagination or self-esteem to think they can do better somewhere else. It's puzzling.

News commentators have talked about "the income gap having gotten wider" in the USA, but I haven't looked at facts and figures for awhile.

^ Yes, clearly there are problems with the economy. My point was addressing the claim that INTPs simply aren't suited for making money.

As I pointed out, we're in what economists consider the "Information Age". Things like entrepreneurship, freelancing, consulting, etc. are easier and more common than ever. In actuality, this is an environment that INTPs are well-suited to flourish in -- in more ways than one.

We're independent, frugal, and love exploring new ideas. It's an excellent combination for today's economy. Outside-the-box thinkers have never had more opportunity than we have now.

I used to agree and still do so to some extent. But there is nothing wrong with simple hedonic pleasures from time to time as well. Minimalism can be nice, but I don't want to spend my life as a suffering monk believing that lifestyle will give me fulfillment. I missed a few opportunities in the past because of my lack of yolo.

Also, the problem that many INTP's may not earn the money they deserve can be a true unfairness, and moral relativism won't solve it. I know INTP's in general don't like complaining, but somehow we must still fight for our place in the world (read: not getting surpressed by stupid SJ's).

The aspiration of resources and status is one of the simple key elements governing human psychology. It can have nasty implementations, but on a macroscopic scale, it works quite well.

I can't say I agree. Lots of people in the 30-50 bracket are miserable. This can be seen in the divorce rate. The vast majority are married with kids, houses 4 times more than they make in a year and a huge amount of debt. The divorce is ironically enough the easiest way to reduce their stress but it isn't the marriage. It's the culture. The idea that you need brand new cars, home renovations, name brand jeans and college degrees, etc. It's the fact that very few people today in this bracket have savings. Very few of them are under leveraged. Most of them live paycheck to paycheck.

Basically their unhappiness can be summarized in their inability to escape. They cannot just up and leave a job they've grown to hate. They can't change careers, they can't find happiness even though they've leveraged themselves into debt for the next 40 years.

It's a depressing situation to be in. No doubts about it.

Mind, not everyone falls into this trap but all you need to do is look at how leveraged 30-50 year old Americans are today. It's a good indicator of how many are unhappy.

#### E404

##### Obsessions of an INTP
I like a lot of these comments (Tesla vs. Edison is a great point). I also agree that we tend to care more about the job than the money.

When I first learned I was INTP I did a lot of research into careers for INTPs since I'm never happy. What I continuously read was that INTPs need stimulation, don't like being in boxes, and like to work independently.

I really like what Ruminator said somewhere up in the comments... My brother and I (he's an INTP too) have talked about how we'd like to do jobs that don't exist anymore. Philosophy, inventor, detective, and many other jobs are not like they were. There are too many restrictions now and too much paperwork. We'd both love to have infinite funds and just work all day solving problems, inventing things, learning, reading... Doesn't everyone? lol

# Reduction problem to another problem

I would like to show that a problem $A$ is $NP\text{-complete}$. So, I am trying to reduce 3-SAT problem to $A$. Reduction is kind of function, let say $f$. What is necessary complexity of $f$? Probably, it has be in $NP$. But, does it mean that $f$ must be a non-deterministic Turing machine working in polynomial time?

• There must be a non-deterministic poly-time reduction. However, I don't know about reductions that use non-determinism. – rus9384 Aug 7 '17 at 17:42
• @rus9384 I think you are wrong – miracle173 Aug 7 '17 at 17:55
• @Carol; 1) search for reduction and complete on this site. 2) $P$ isnt a good name for a problem in this context because $P$ is also used for the complexity class $P$. – miracle173 Aug 7 '17 at 17:57
• @miracle173, why am I wrong? Every poly-time deterministic reduction is also poly-time non-deterministic reduction. Reversal is true iff $\mathsf{P = NP}$. – rus9384 Aug 7 '17 at 18:21
• Hint: look at the definition of NP-completeness. It's all there. – Raphael Aug 7 '17 at 21:31

No, $f$ need not be a NDTM. To prove a problem is NP-complete by reducing another NP-complete problem to it requires only a Karp reduction, which is a polynomial-time deterministic reduction. So $f$ would live in the complexity class FP.
