I''m trying to get a bit into programming a wallstreet trader like game, based on a somewhat reallife economic system. I mean you have one product, which fluctuates in price eg. price can be higher/lower/stable. or the price can skyrocket to extreme heights. I have been trying to find books or sites, where I can learn more from this subject, but I''m not able to find one which can help me on the way. Does anyone of you know a site or whatever, where I can read more about this?

##### Share on other sites
check your local library. There should be plenty about this. And many games like this have been created, although proprietary. I played one a few years ago in a nationwide contest. Many academic institutions implement games of this kind.

##### Share on other sites
I have been looking for books about the subject, but I can''t seem to find one. Do you know any good titles about the maths of creating a good economical like system, like I discribed above?

##### Share on other sites
I suggest taking Macro-economics or Micro-economics, or get a book on the subject matter. Depending on how complex you want to make it, you will need a lot of facts. You can either randomly flucuate the prices or simulate traders..

Why Not?

##### Share on other sites
yes, a system like that, if I know what you mean, is going to be huge. An true economic AI simulation would be hard to code.

"There are two types of langages, those that everyone complains about, and those that no one uses."

I see what you mean, It doesn''t have to be a complete simulation, but it has to be a somewhat low level sim which at first does the basics of an economical system.
I''m not sure whether you are familiar with the game dopewars? at first I want to built a economical like system like this, eg. prices up, prices down, prices stable, prices skyrocket or drop to almost nothing. Just a micro economic system which only has a few factors.

Koopman,
The responses to your question, for the most part, have been correct. But to do a simulation that is a game - it isn''t necessary for you to have a Ph.D. Economics.

Do a search at Google for Economics or Macro+Economics or Micro+Economics and you should find enough material to give you headache after reading.

I do have a caveat to my above statement. The stock market is a secondary market and thus is extremely difficult to predict. Many have tried and none have succeeded. There really isn''t any book that will explain how you would simulate this entity precisely.

If I were going to simulate the stock market in a wall street trader game I would first create a a made up company or a couple that produce some sort of product (stay away from service type companies to start, were trying to get the model down here). When a company is placed in the market they set aside a certain number of public available stocks and they sell these stocks at a set price. To keep the example simple, let''s say you create a company that manufactures watches. They set aside 10,000 stocks for the initial public offering (IPO) and the value of each stock is $1.00 - this could be calculated based on the current estimated value of the company/number of stocks. So, in my example the company is worth$10,000.

When the IPO takes place, the traders purchase the stocks sometimes for more and *GASP* maybe less. Let''s say that out of the 10,000 shares that were offered they were sold like this:

1000 shares sold for the asking price of $1.00 5000 shares sold for$1.15
and the final 4000 sold for $1.25 The total secondary market value of the company is$11,750 - not bad huh? I can''t remember how this works IRL but, I think the company is given a % of this - you could just give them the entire amount and it would not hurt the simulation. Any way you now have a opening value of $1.00 and a closing value of$1.25 ^.25 for the day.

Next you need a simulated group of consumers - which control the demand. The company determines the supply initially and after the initial demand is received. All of this would have to be AI driven (because it happens in the background).

The player in the game, I assume to be the trader would have been making the purchases of the IPO (if he wanted) and other stocks that you have simulated.

In the background the company is churning out products, consumers are making purchases or inventory could be piling up - whatever you want to simulate. In addition the company would post quarterly earning reports and analyst would be posting their take on each company that is available (a big job in and of itself - all AI).

Hmmm, this was all off the top of my head... so, don''t bash me - but I think that I''ve show you that even a high level simulation of the stock market would be difficult... especially when it is all AI driven.

Good luck to you, I would like to see what you come up with!

# Javascript Calculate Time Difference Between Two Timestamps

/SDF/CMO_DATETIME_DIFFERENCE. Answer: To retrieve the total elapsed time in minutes, you can execute the following SQL: select (endingDateTime - startingDateTime) * 1440 from table_name; Since taking the difference between two dates in Oracle returns the difference in fractional days, you need to multiply the result by 1440 to translate your result into elapsed minutes. The equation of time is the difference between time as read from a sundial and a clock. To get time difference you need to use TimeSpan object, with code like this: TimeSpan ts = DateTime1 - DateTime2; For example, if you want to calculate time difference between server time and UTC time: [ C# ] protected void Page_Load(object sender, EventArgs e) {.

# Particle Spacing in a Vacuum

Four questions: (To start off, I know very little about physics it isn't even funny (I probably use a ton of wrong terms here and leave out vital information, if so I will try to edit it in as you point it out!), Anyways, I have been always curious about this scenario though so I finally figured I'd ask some people who actually know what they are talking about)

First question: Theoretically speaking, if I have a vacuum that is a closed system, it's made of walls that are 100% nonreactive and have no electromagnetic force, strong force, weak force, gravitation force, or anything, but they can still restrain things placed inside the box (without any interaction on the particles, but instead just by the laws of this system)

If I place 1 particle in the box will it stay exactly where I placed it, or will it somehow move to the center of the box thus distancing itself as far as possible away from each wall? (I've drawn a 2D demonstration)

Now, if I place a second particle in, will they both stay where I placed them, will they divide the box in half in some way (I just gave 1 example, there are many) and then both move to the center of those halves, will they space themselves as far apart as possible (pushing themselves against the nearest corners of the box), or is there some ring of energy around particles that I don't know about that has a statistical radius and they would just distance themselves as much as the "reach" of this ring so that the rings aren't touching?

Or will something else happen?

Second question: I'm assuming different things will happen if the particles are different things, for example if Particle A was a proton and Particle B was an electron they would just pull together? Or the electron would begin orbiting the proton (Or would they even both start orbiting each other?) (If either of these are the case what determines if the orbiting is clockwise or counter-clock-wise (Or whatever the 3D equivalent of these would be, does spin determine?)? What are some particles that would react different ways, for example 2 photons, a proton and a proton, a proton and an electron, etc. Or would it not matter?

Third and Fourth questions: What would happen in the same scenario except the walls are reactive, they are made of steel, or carbon fiber, or something strong enough to support a vacuum?

-

According to the laws of quantum mechanics (you might have heard of the uncertainty principle) if you place a particle in a given position, e.g. near the corner, you are doing so by measuring its position with great precission. This means that you loose all precission about its velocity, therefore in a given instant after you placed the particle it could actually be anywhere within the box, not necessarily the center. There will be a certain probability density that it will be found in any given place of the box. If you add a second particle, then things depend of the type of particles you are dealing with (recall all particles are either fermions or bosons). If both particles are distinct (no matter if they are bosons or fermions) then they can "occupy the same point in space" without problems, the same happens if they are bosons (whether of the same type or not), but if you placed two identical fermions in the box there will be some kind of effective repulsion between them (coming from Pauli's exclusion principle), so in some sense there are some "rings" preventing the particles to get too close to each other (i.e. of having the same quantum state), this is the force that makes everyday matter seem solid.

Second question: If you place an electron and a proton, chances are they will eventually bind into a hydrogen atom, radiating a photon in the process. The rotation sense only has a meaning if you define it with respect to some axis in quantum mechanics, say the $z$ axis, in such case the angular momentum of the system is conserved, so the final angular momentum depends of the initial angular momentum of the particles before they bind (if they bind).

Pairs of particle with the same charge will not bind in the conditions of the experiment. Photons will not bind under any known circumstances, so far as I know.

Third and Fourth questions: In a real life experiment with reactive walls things will complicate, in principle there is a chance the particles can escape of the box by tunneling effect (this also depends very strongly of the energy the particles have), but most importantly it is almost certain that they will interact with the walls and eventually they will not be the only particles in the box, there will be "parts of the box" inside.

Chances are it will be very difficult to even be sure that you are observing the same particle in the conditions of the experiment, unless more constrained conditions are inforced on the particles (as a light-trap for cooling)

Thankyou! Wow, you answered every single question ahaha +1 I do have some questions though... What's the "tunneling effect" not sure that I've ever heard of that. Also, what if the walls were made of ultra strong electromagnetic fields so that more particles could not enter the closed system, or am I delusional about what an electromagnetic field is and they are actually made of particles or require a medium? Lastly, what is "Light-trap" that you mentioned at the end? Thanks again so much! God bless! –  Albert Renshaw Oct 30 '13 at 16:07
Oh and is it possible for a particle to have a velocity of 0, other than energy being at absolute zero kelvin, if so can I still measure position exactly? And would it repel another particle if they were both identical fermions? –  Albert Renshaw Oct 30 '13 at 16:08
You are welcome. The tunneling effect is a quantum phenomenon where a particle is able to go trough barriers even if the particle does not have enough energy to do that. In your first experiment the walls were perfect so even tunneling will not work, but when they are made of an actual substance tunneling may take place. Now, using electromagnetic fields, specially strong ones, will actually not work very differently from the actual wall, again tunel effect may take place. Also, under certain circumstances electromagnetic fields may interact with the particles inside and create more particles, –  Rogelio Molina Oct 30 '13 at 22:44
I am afraid that even if one is able to cool down everything at zero kelvin (in principle this is not possible), thus having a particle with zero speed, Heisenberg's uncertainty principle implies that you will loose all knowledge of where the particle is. That means you cannot determine its position with any precission. (And if you were to determine its position then you would loose information about its velocity, so you wouldn't know that it is zero any longer) –  Rogelio Molina Oct 30 '13 at 22:48
Awesome! Thankyou very much :) –  Albert Renshaw Oct 30 '13 at 22:49

# A shell is fired from a canon with a velocity v at an angle $\theta$ with the horizontal. At the highest point of its path it explodes into two pieces of equal masses, one of the pieces retraces its path to point of throw. what is speed of second piece immediately after explosion

$(a)\;3v\; \cos \theta \quad (b)\;2v\; \cos \theta \quad (c)\;v\; \cos \theta \quad (d)\;\frac{3}{2}v\; \cos \theta$

Can you answer this question?

A shell fired at angle $'\theta'$ velocity of shell at highest point is $v \cos \theta$
Let its mass be m
speed of one piece $=v \cos \theta$
Let speed of other piece $=v'$
Using conservation of momentum
$mv \cos \theta=\large\frac{m}{2}$$v \cos \theta+\large\frac{m}{2}v'$
Therefore $v'=3v \cos \theta$
Hence a is the correct answer.

## Solution 1

Hint: What is the probability of one toss resulting in heads? How do you compute the probability of success in two independent events? How about twelve?

## Solution 2

Hint: The propbability of $n$ independant events each having probability $p$ occuring is $p^n$.

• Shailesh less than a minute

What is the probability of every coin displaying HEAD if a coin is tossed 12 times. Is it $\frac{1}{12}$ or $\frac{1}{1024}$?

• ronno over 8 years
Why do you think either of those two numbers is the answer?
• Shailesh over 8 years
Okay ..Actually i have 3 options in test paper .last 1 was none of them .Can u solve the query
• ronno over 8 years
In any case, do you want the probability of every toss resulting in heads or at least one toss resulting in heads, or something in between?
• Shailesh over 8 years
every toss resulting in heads o
• Frenzy Li over 5 years
• Don Larynx over 8 years
This doesn't answer OP's question. The probability of 1 head appearing in 12 tosses is certainly not $\frac{1}{2^{12}}$.
• Shailesh over 8 years
Yes i think u r right
• ronno over 8 years
@DonLarynx, actually, it does, see OP's comments to the question.
• Don Larynx over 8 years
Ah okay. My apologies.
• MPW over 8 years
And so the probability of any specified sequence of outcomes in tossing a fair coin 12 times is $1/2^{12}$. Nothing special about all HEADS.
