#### Free Energy

Free energy (G) is energy that is available, or free, to do work! Spontaneous reactions release free energy as they proceed. The formula to find the free energy change of a reaction involves the change in enthalpy (∆H) and entropy (∆S):

ΔG=ΔHTΔS\begin{align*}\Delta G^\circ=\Delta H^\circ - T \Delta S^\circ\end{align*}

Note: the T in this equation is the temperature in Kelvin, which is always positive.

What are the units for the calculation of ∆G?

Keeping in mind that a spontaneous reaction is one that releases free energy, making the sign of ∆G negative, fill out the following chart to help you remember the different outcomes of ∆G:

 ΔH\begin{align*}\Delta H\end{align*} ΔS\begin{align*}\Delta S\end{align*} ΔG\begin{align*}\Delta G\end{align*} − value (exothermic) + value (disordering) always negative - never positive + value (endothermic) + value (disordering) negative at higher temperatures − value (exothermic) − value (ordering) negative at lower temperatures + value (endothermic) − value (ordering) never negative - always positive

Why does the temperature matter for the second and third combinations above?

#### Free Energy Change

Based on the following equation:

CH4(g)+H2O(g)CO(g)+3H2(g)\begin{align*}\text{CH}_4(g)+\text{H}_2\text{O}(g) \rightarrow \text{CO}(g)+3\text{H}_2(g)\end{align*}

If the ∆H˚ is +206.1 kJ/mol and the ∆S˚ is +215 J/K • mol, calculate the ∆G˚ at 25˚C. Is the reaction spontaneous?

Remember: the ˚ refers to the use of standard conditions when calculating the free energy.

 Physics , 2013, Abstract: We investigate the existence of envelope soliton solutions in collisionless quantum plasmas, using the quantum-corrected Zakharov equations in the kinetic case, which describes the interaction between high frequency Langmuir waves and low frequency plasma density variations. We show the role played by quantum effects in the nonlinearity/dispersion balance leading to the formation of soliton solutions of the quantum-corrected nonlinear Schrodinger (QNLS) equation.
 Physics , 2004, DOI: 10.1063/1.1819935 Abstract: Quantum Zakharov equations are obtained to describe the nonlinear interaction between quantum Langmuir waves and quantum ion-acoustic waves. These quantum Zakharov equations are applied to two model cases, namely the four-wave interaction and the decay instability. In the case of the four-wave instability, sufficiently large quantum effects tend to suppress the instability. For the decay instability, the quantum Zakharov equations lead to results similar to those of the classical decay instability except for quantum correction terms in the dispersion relations. Some considerations regarding the nonlinear aspects of the quantum Zakharov equations are also offered.
 Physics , 2011, Abstract: A numerical analysis of the self-interaction induced by a relativistic electron/positron beam in the presence of an intense external longitudinal magnetic field in plasmas is carried out. Within the context of the Plasma Wake Field theory in the overdense regime, the transverse beam-plasma dynamics is described by a quantumlike Zakharov system of equations in the long beam limit provided by the Thermal Wave Model. In the limiting case of beam spot size much larger than the plasma wavelength, the Zakharov system is reduced to a 2D Gross-Pitaevskii-type equation, where the trap potential well is due to the external magnetic field. Vortices, "beam halos" and nonlinear coherent states (2D solitons) are predicted.
 Benjamin Texier Mathematics , 2006, DOI: 10.1007/s00205-006-0034-4 Abstract: This paper continues the study of the validity of the Zakharov model describing Langmuir turbulence. We give an existence theorem for a class of singular quasilinear equations. This theorem is valid for well-prepared initial data. We apply this result to the Euler-Maxwell equations describing laser-plasma interactions, to obtain, in a high-frequency limit, an asymptotic estimate that describes solutions of the Euler-Maxwell equations in terms of WKB approximate solutions which leading terms are solutions of the Zakharov equations. Because of transparency properties of the Euler-Maxwell equations, this study is led in a supercritical (highly nonlinear) regime. In such a regime, resonances between plasma waves, electromagnetric waves and acoustic waves could create instabilities in small time. The key of this work is the control of these resonances. The proof involves the techniques of geometric optics of Joly, M\'etivier and Rauch, recent results of Lannes on norms of pseudodifferential operators, and a semiclassical, paradifferential calculus.
 Yun-Mei Zhao Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/854619 Abstract: A generalized -expansion method is proposed to seek the exact solutions of nonlinear evolution equations. Being concise and straightforward, this method is applied to the Zakharov equations. As a result, some new Jacobi elliptic function solutions of the Zakharov equations are obtained. This method can also be applied to other nonlinear evolution equations in mathematical physics. 1. Introduction In recent years, with the development of symbolic computation packages like Maple and Mathematica, searching for solutions of nonlinear differential equations directly has become more and more attractive [1–7]. This is because of the availability of computers symbolic system, which allows us to perform some complicated and tedious algebraic calculation and help us find new exact solutions of nonlinear differential equations. In 2008, Wang et al. [8] introduced a new direct method called the -expansion method to look for travelling wave solutions of nonlinear evolution equations (NLEEs). The method is based on the homogeneous balance principle and linear ordinary differential equation (LODE) theory. It is assumed that the traveling wave solutions can be expressed by a polynomial in , and that satisfies a second-order LODE . The degree of the polynomial can be determined by the homogeneous balance between the highest order derivative and nonlinear terms appearing in the given NPDEs. The coefficients of the polynomial can be obtained by solving a set of algebraic equations. Many literatures have shown that the -expansion method is very effective, and many nonlinear equations have been successfully solved. Later, the further developed methods named the generalized -expansion method [9], the modified -expansion method [10], the extended -expansion method [11], the improved -expansion method [12], and the -expansion method [13] have been proposed. As we know, when using the direct method, the choice of an appropriate auxiliary LODE is of great importance. In this paper, by introducing a new auxiliary LODE of different literature [8], we propose the generalized -expansion method, which can be used to obtain travelling wave solutions of NLEEs. In our contribution, we will seek exact solutions of the Zakharov equations [14]: which are one of the classical models on governing the dynamics of nonlinear waves and describing the interactions between high- and low-frequency waves, where is the perturbed number density of the ion (in the low-frequency response), is the slow variation amplitude of the electric field intensity, is the thermal transportation velocity of the
 Guy Metivier Mathematics , 2007, DOI: 10.1016/j.physd.2008.03.024 Abstract: In this paper we study an initial boundary value problem for Zakharov's equations, describing the space propagation of a laser beam entering in a plasma. We prove a strong instability result and prove that the mathematical problem is ill-posed in Sobolev spaces. We also show that it is well posed in spaces of analytic functions. Several consequences for the physical consistency of the model are discussed.
 Physics , 1995, DOI: 10.1142/S0218271895000508 Abstract: We apply the algebraic quantization programme proposed by Ashtekar to the analysis of the Belinski\v{\i}-Zakharov classical spacetimes, obtained from the Kasner metrics by means of a generalized soliton transformation. When the solitonic parameters associated with this transformation are frozen, the resulting Belinski\v{\i}-Zakharov metrics provide the set of classical solutions to a gravitational minisuperspace model whose Einstein equations reduce to the dynamical equations generated by a homogeneous Hamiltonian constraint and to a couple of second-class constraints. The reduced phase space of such a model has the symplectic structure of the cotangent bundle over $I\!\!\!\,R^+\times I\!\!\!\,R^+$. In this reduced phase space, we find a complete set of real observables which form a Lie algebra under Poisson brackets. The quantization of the gravitational model is then carried out by constructing an irreducible unitary representation of that algebra of observables. Finally, we show that the quantum theory obtained in this way is unitarily equivalent to that which describes the quantum dynamics of the Kasner model.
 Ming Song Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/308326 Abstract: We use the bifurcation method of dynamical systems to study the traveling wave solutions for the generalized Zakharov equations. A number of traveling wave solutions are obtained. Those solutions contain explicit periodic blow-up wave solutions and solitary wave solutions.
 R. Myrzakulov Physics , 1999, Abstract: The (2+1)-dimensional integrable Zakharov equations and their reductions are considered
 Ping ZHANG Studies in Mathematical Sciences , 2010, Abstract: In this paper, we obtain several types of exact traveling wave solutions of the generalized Zakharov equations and the complex coupled KdV equations by using improved Riccati equations method. These explicit exact solutions contain solitary wave solutions, periodic wave solutions and the combined formal solitary wave solutions. The method can also be applied to solve more nonlinear partial differential equations. Key Words: Improved Riccati equations method; Generalized Zakharov equations; Complex coupled KdV equations; Solitary wave solutions; Periodic wave solutions

Hi,

Several extensions I installed produce lists (PageViews, recent changes, etc...). They all do so by presenting the results in some table on screen. What I am looking for is a tool to download/export whatever list displayed on screen in these special pages into some file (CSV, whatever format ...) that then can be handled in Excel or any other application...

Till now, in the vast list of extensions I never found such a tool. Does such a thing exist ? Could you point out to me where to find it or how to do this ....

thanks,

## img_auth.php and additional images repo

Hi,

Our image folder has automatic hashing configured. Additionally we have a separate folder "images/staffimages" used by our own implemented extension. Now we'd like to hide direct links to the images with img_auth.php. The settings work fine so far for everything hashed in the MW repo. However images in our "staffimages" repo become not accessible anymore. Is there a way e.g. via apache2/Aliases or a LocalSettings.php directive to also cover our separate repo "staffimages" by the img_auth.php?

When I open a page having staffimages, first a rectangle of the correct size of the image opens, then disappears. In the log I see (sry, can't connect from this machine, so no copy of the orig text available): wfForbidden Hdr: access denied .../staffimages/abc_123123.jpg does not exist.

images/.htaccess:
Deny from All

LocalSettings.php:
$wgHashedUploadDirectory = true;$wgUploadDirectory = "images";
$wgUploadPath = "/img_auth.php"; sry, the wiki is only internally used, so no link. :/ MediaWiki: 1.25.1 Server: Ubuntu 14.04.2 LTS mysql-server: 5.5.43-0ubuntu0.14.04.1 php5: 5.5.9+dfsg-1ubuntu4.9 Thanks in advance 176.10.108.509:47, 3 July 2015 ## Backup: Extract database? I have the following situation: Server HDD crash with just a backup of the mysql data base. The former admin is not available anymore and we have no knowledge of MySQL or PHP, Media wiki is some older version from ~2010. I can see all the wiki pages in mysql\data\wiki\text.MYD. However it is one huge file with 1.3 million lines and it contains every version of every page. Is it possible to extract the wiki pages in some useful form? 84.143.94.12313:39, 25 June 2015 In order to set up the wiki again, you need two things: The wiki files (the MediaWiki source code, best would be exactly that version, which you had before, and custom things in your install like uploaded images and the LocalSettings.php file) and secondly the database. If you have the complete mysql/data/ folder, you might be very lucky. I guess that with all files from there, you should be able to restore the whole database. Reading up here http://stackoverflow.com/questions/879176/how-to-recover-mysql-db-from-myd-myi-frm-files makes it sound like it is simple to restore the tables, if they were of the MyISAM type (= you have .myd, .myi and .frm files). If you have InnoDB types, you have to do some additional magic, see http://stackoverflow.com/questions/10934745/restore-the-mysql-database-from-frm-files. 88.130.101.15514:40, 25 June 2015 Edited by 2 users. Last edit: 05:42, 27 June 2015 Thank you! I was able to set up xampp on a local pc, copy the old mysql database to mysql\data\ and run mysql with --skip-grant-tables to disable the password check. Then I could open this database in the current version of mediawiki without problem and save all pages I needed. 84.143.94.17506:53, 26 June 2015 Okay, turns out there is one problem left: Every wiki page that contains a special character like ü, ä, ö is now missing. For example the page "Technik" is now accessible but "Übersetzen" is now red and missing. Is there some kind of text encoding option that I have to change? 84.146.102.8305:29, 3 July 2015 Maybe you need to set$wgDBTableOptions to specify the correct charset. But that may be hard to know beforehand. If it was an old installation, it may be latin1, or utf8, or who knows...

## Enhancing LaTex support on Wikiversity

I would like to enhance the MediaWiki support on Wikiversity so that the following works: $$\label{squ} \D := \vcenter{\xymatrix @=3pc {S \ar @<1ex> [r] ^{s^1} \ar @<-1ex> [r] _{t^1} \ar @<1ex> [d]^{\, t_2} \ar @<-1ex> [d]_{s_2} & H \ar[l] \ar @<1ex> [d]^{\,t} \ar @<-1ex> [d]_s \\ V \ar [u] \ar @<1ex> [r] ^s \ar @<-1ex> [r] _t & M \ar [l] \ar[u]}},$$

The expression is put between <:math>[/itex].

## Moving to MSSQL

Hi all,

I'm running MW1.17 on IIS7 and MySQL server for now. I need to move the database to our company Microsoft SQL Server 2008.

I tried the MS Migration Assistant, but it failed.

In the SQL Management Studio I tried to import the table definitions form maintenance/mssql/tables.sql, but it failed with error Msg 156, Level 15, State 1, Line 33 Incorrect syntax near the keyword 'user'.

Can somebody help me?

94.113.242.6614:20, 7 November 2011

Hi, you have to modify the file Database.php, function: fieldNameWithAlias, line 2566, you have to put the brackets in the alias.

return $name . ' AS ' .$alias;

for this

return $name . ' AS [' .$alias.']';

a bit late, lol

89.167.129.5014:10, 2 July 2015

Honestly, I would say: You have to install MySQL. While MediaWiki should theoretically support MSSQL, this support compared to MySQL is way less mature. You should expect a variety of things to be not working or having bad performance, just because not so many people use MediaWiki with MSSQL and because it's optimized for MySQL, likely with InnoDB tables in mind.

So, if you want to solve this issue properly, use MySQL. This is the real fix.

## Landing page after saving information via form

Hi,

I have a page that includes a form to manually add and save data to the page. Once I click on the link to the form, fill it out, and save it, it goes back to a different landing page than the base page (with the link to the form). I want it to go back to the original page that i accessed the form link from. Any help would be greatly appreciated.

## Include files of de:wikipedia

My version is 1.23.6 Till today morning I used nearby of commons-files files from de-wikipedia. But since few hours only "Es ist keine Datei dieses Namens vorhanden." No file with this name exists appears and not a connection to the wikipedian file exist. As sample http://regiowiki.at/wiki/Datei:Logo_Polizei_AT.svg works okay. In our Localsettings.php nothing of changes were made. So perhaps some changes from Wikipedia-de. Perhaps somebody knows more thx in advance

12:58, 16 June 2015

Sounds to me like you have the same issue as this user here: Thread:Project:Support_desk/InstantCommons_suddenly_is_not_working

For him the "solution" was to wait and the issue fixed itself. Somehow...

88.130.116.3014:38, 16 June 2015

17:02, 16 June 2015

I have tried it with 'https://de.wikipedia.org/w/api.php', - but the problem is not solved. Commons works okay. --

20:35, 16 June 2015

In the meantime the commons doesn't work too :-(( - but with a little difference. With commons the link to the image appears and with clicks I can reach the file. Other in wikipedia - not a link appears. You can see it at mainpage of http://regiowiki.at --

04:52, 18 June 2015

Also see Manual:$wgForeignFileRepos. It is important to use HTTPS and not HTTP in the links pointing to the Wikipedia commons. The Wikimedia guys have changed their setup, redirecting people from HTTP to HTTPS and this change basically caused the issue we got reported here. This change has been reverted for now (so that it's again working also with HTTP), but it is still planned to switch to HTTPS in the future (see task T102566). The solution is to use HTTPS in the URLs pointing to the commons repository!$wgForeignFileRepos has to be adjusted accordingly! See Manual:$wgForeignFileRepos! 88.130.116.21412:55, 20 June 2015 I set this in the localsettings:$wgForeignFileRepos[] = array(

  'class'                   => 'ForeignAPIRepo',
'name'                    => 'commonswiki', // Must be a distinct name
'apibase'                 => 'https://commons.wikimedia.org/w/api.php',
'hashLevels'              => 2,
'fetchDescription'        => true, // Optional
'descriptionCacheExpiry'  => 43200, // 12 hours, optional (values are seconds)
'apiThumbCacheExpiry'     => 86400, // 24 hours, optional, but required for local thumb caching
);

then I try with

$wgUseInstantCommons = yes and no have the same effect - a link will be created but not a thumb will be created //$wgUseInstantCommons = ; -> not a link is created

## adding CSS at onBeforePageDisplay hook

Hello,

In an extension Im working on, I add additional modules containing CSS at the onBeforePageDisplay hook. The problem is that when the page loads, first the normal mediawiki CSS is displayed for a milisecond, and only after this my CSS is loaded.. which doesn't look too nice. How can I resolve this? Thanks :]

146.175.202.3014:02, 25 June 2015

But are you adding a style block, or an external stylesheet ? Can you give links perhaps ?

20:25, 28 June 2015
Edited by another user.
Last edit: 15:52, 30 June 2015

Thanks for the reply :] Im adding an external stylesheet. The idea of what I want is simple: I have a custom SpecialPage on which I have added HTML buttons and I want to change the way these buttons look like. So I want to load a custom .css file only when the user lands on my SpecialPage. Unfortunately I have not uploaded my code to the web yet, so I can't give you a link, but my basic code for the hook looks like this:

  public function onBeforePageDisplay(OutputPage &$out, Skin &$ski ){

$page_title =$out->getPageTitle();

if($page_title === 'My SpecialPage Title Name'){$out->addModules("ext.myModule");
}

return true;
}

ext.myModule then retrieves a small .css file with the changes I want for my buttons:

#button{
width: 30em;
height: 1.5em;
cursor: pointer;
}

#letter_button{
cursor: pointer;
}

But after that I have displaying pages in wrong way. Could anybody help me? 10:31, 24 June 2015 This is usually caused by an unclosed HTML element (div, table, etc), or even a closing element that has no matching start element (effectively closing too early a previous element of the page. Check the HTML codes of the page or templates. 11:42, 24 June 2015 Not sure. In my old database that page was OK. I check all and all looks OK. Look on that page too http://wiki.westeros.pl/index.php?title=Szablon:Navbox_generic/doc 12:16, 24 June 2015 If you inspect the generated HTML (better if you download the page as raw, since browser may auto-correct mismatched tags and change the original HTML) you'll see that it outputs several encoded HTML because it's not generating it properly [1] (search for <) I think those and  tags shoud be using wiki tables instead. 17:31, 24 June 2015 Yeah. So what should I do? Install some extension?

So, I think it's a permissions thing in general and maybe an SELinux thing in particular? But I can't figure it out. I've set the images dir chmod -R 777. Any idea what's up here?

If you think it's a SELinux problem, try disabling it and see if upload works.

## Mediawiki Main Page

Hi folks,

Currently, I have a like icon which display on every page. But right now I would like it to display on all other pages except the main page

My code to display the like icon is here (https://dpaste.de/ENfm)

On line 470 is where I check if it is a main page, but I am having issue. It is giving me the error (PHP Fatal error: Using $this when not in object context) On line 32 is where the method is being declared. How should I check if it is a main page. Using parser? Using outputToHTML? Please advise. Greatly appreciated! Thanks all! Newbie16:44, 1 July 2015 ## How can i translate pages in this site to zh-hant? How can i translate pages in this site to zh-hant?

Last edit: 14:43, 1 July 2015 I have enable the following: https://www.mediawiki.org/wiki/Manual:$wgUrlProtocols When i link an external link through Visual Editor: [file://\\network\shared folder\application file\] , this will not work because it will get concatenated at the space because it can't recognize space but %20 instead: file://\\network\shared.

I tried using {{urlencode:string|PATH}}, but it replaces my \\ with %5C as well. I would only like the code to replace spaces with %20. Doing this [file://{{urlencode:\\network\shared folder\application file\|PATH}}]; result in : file://%5C%5Cnetwork%5Cshared%20folder%5Capplication%20file%5C And the browser does not recognize %5C

206.51.148.213:50, 1 July 2015

Apparently, urlencode with PATH won't work, because it encodes "/" characters, which from my understanding it shouldn't.

You should use forward slashes in URLs, and it should end with 5 forward slashes at the start: file://///network/shared%20folder/application%20file.

Try to not use spaces in URLs, or use URLENCODE on every segment of the URL, not on the whole URL.

## how to get creator/owner of the created article

Hi all,

I would like to ask is it possible to get the author/owner/creator of the article created? Is it to use wgUser?

Thanks all for your kind assistance and time!!!!

Hi!

When you speak of the "creator" of an article, I guess that you then mean the user, who created the first revision of that article, right?

When and where do you want to get that information? Somewhere inside PHP obviously... But where should it be used? Maybe you find an according method inside the article object...

88.130.81.11217:18, 28 June 2015

Hi,

I really appreciated your response! Yes, you are correct. I want to get the user who created the first revision of that article. I have already retrieved the title but I am not sure on how to retrieve the user (http://postimg.org/image/oj3ybel2x/) . I want it to be displayed like that.

Just to add on, the "Requests:" is a namespace and the title is displayed on the main page using the newestpage extension. I used Special:Newestpages/Requests/5

I tried to look at the link you provided but could not see any documentation that would aid me in getting the creator.

03:23, 29 June 2015

You need to access a WikiPage class for that page and use the getOldestRevision method. It returns a Revision class that you can use to get the user. You can navigate the documentation for this.

15:40, 30 June 2015

I managed to get the author of the article but I am facing another issue now. :(

Right now, I am retrieving the content of the article and displayed on my main page. But it is giving me the html format instead. (As seen in this picture: http://i62.tinypic.com/99mlvd.png) It is showing me == (text here) == instead of the header.

I have my full code here (https://dpaste.de/ro3r#L329). I've tried to output \$wgOut->addWikiText on line 197, but it is giving me weird characters as shown here (http://i60.tinypic.com/eslrhy.png)

I have also tried implementing parser as seen in line 133 but it is not going into that function. Why is that so?

Really really appreciated your response and time and help and everything!!!!! Thank you so much!!!!!!!

16:10, 30 June 2015

As said in QINU fix, apparently you need to use the method recursiveTagParse of the parser

# Snooze Tabs For Firefox 2.103 Crack With Product Key [Mac/Win] [April-2022]

Snooze Tabs is a smart browser extension part of Firefox Test Pilot, designed to help you avoid distractions, focus on work and remember important things by scheduling tabs to open at a later time when you're available.
Schedule tabs to reopen later in Firefox
Wrapped in a clean, modern-looking interface, the addon can be accessed from a small icon next to the address bar. Effects are only applied to the currently opened tab every time you perform an action.
Tabs can be scheduled to reopen later on the current or next day, next weekend, next week or month, or the next time you launch Firefox. Each of these options has default times.
Choose preset profiles, set the date and time, manage snoozed tabs
"Later Today" is set to 3 hours from the current time. "Tomorrow" means the following day at 9 am, and "This Weekend" is represented by the nearest Saturday at 9 am. "Next Week" and "Next Month" mean exactly one week and one month in the future, both at 9 o'clock in the morning. However, it's possible to choose different dates and times after selecting any option.
Once the decision is made, Snooze Tabs displays a message and asks for confirmation. It's necessary to confirm this or the event will not be taken into consideration. Afterward, the pin gets closed and reopened at the scheduled time (a message pops up in the lower-right corner of Firefox to draw your attention).
Furthermore, you can go to the tab management area where, besides viewing and deleting any snoozed tabs, you can edit the scheduled times and dates, as well as skip the confirmation messages in order to schedule the events right away.
Potentially great Firefox addon with plenty of room for improvements
For the most part, Snooze Tabs worked well in our tests. But we've noticed that the current version has several glitches. For instance, when creating a new alarm, it's only possible to change the default time, not the time, although this option is visible. In some cases, this failed to produce the desired effect (the confirmation message wasn't shown and the event wasn't added to the manager). The issue was eventually resolved by restarting the web browser.
When trying to edit the scheduled date and time, the clock disappeared sometimes. Also, in one case, the Snooze Tabs window didn't get enlarged to fit the calendar and clock. In all cases, scheduled tabs didn't reopen automatically when this should have happened after restarting Firefox (this was triggered only after clicking the addon's icon).
All aspects considered, Snooze Tabs can be a great addon for any Firefox user who easily gets distracted while trying to work or study. However, our tests have shown that it has many stability issues at the moment. We're looking forward to improvements and new features (such as writing notes to snoozed tabs).

Invariant of a quadratic form

The following article explains a method for finding an orthogonal matrix A such that $f(Ax) = 0$.

I was wondering what would be the purpose of transforming the quadratic form $f$ to the form $g$ where $g$ is a symmetric form with respect to the orthogonal matrix $A$.
I would like to know the advantage of doing such a thing, and not just the result of $g$.

A:

If you think of $f$ as a bilinear map $\phi\colon V \times W \to \mathbb{F}$, then $\phi^*\colon \mathbb{F} \to V^* \times W^*$ is a quadratic form, since the restriction of $\phi^*$ to any of its domain spaces is linear.
Similarly, if $\tilde{f}\colon V \times W \to \mathbb{F}$ is any quadratic form, then the restriction of $\tilde{f}^*\colon \mathbb{F} \to V^* \times W^*$ to any of its domain spaces is linear.
Also, for any nonzero $v \in V$, there exists a nonzero $w \in W$ such that $f(v,w) = 0$. This follows from the fact that $V$ is $f$-

Snooze Tabs – Window Snoozing Extensions for Firefox

“Greasemonkey users: If you’ve tried to do more complex things with jQuery, you’ve probably used the MasterRebel Library. It adds a ton of super powers to your life. You could spend a month learning what you can do with it, or you could try my little book called “Mastering the MasterRebel Library.” It explains a little bit of everything, and how you can do things you didn’t think were possible. It’s like Pokemon Go except with puppets. See my webpage for details.

The downside of the MasterRebel Library is that the latest version (1.0) has a few important bugs. I will fix them as fast as I can, but I need some help. So I’ve put together a little contest. The contest is to determine which of the two pages is the prettier.

It is a dead simple contest. On this page, you can add comments. On the other page, you can find the entries. Click the “Unlock Free MasterRebel Library” button on the page with the comments, and click the button in the bottom left corner. Then you can see all of the entries. The first one is the best, and the second one is second best. I’m keeping the source of the entries for a few days, so be sure to check back later to see the winners.

I will announce the winners at the end of the month. I will also be putting out a new version of the MasterRebel Library. In the new version, I’m adding some new features. You won’t be able to use them in the contest, but I’ll release them to everyone at the end of the month.

If you want to help me make a better page and a better contest, tell your friends about the contest, or send a comment here.

Dailymotion Attach Videos does what it says on the tin. It uses the Dailymotion API to search your inbox for attachments from dailymotion.com, and then adds them to your Contacts. It also allows you to forward all DM videos that you own or have watched to a single inbox in one go. Once you choose, Dailymotion Attach Videos will create a new inbox which displays your forwarded videos, and when it discovers new videos to attach it will search for them, and download and attach them. You can even save attachments to a single contact.
When you receive a video attachment, the link will be added to the new inbox, and a notification will be sent to your Inbox. The idea is that you can then easily share it with a contact. If it’s a new video, Dailymotion Attach Videos will automatically forward it to your inbox.
All the features of Dailymotion Attach Videos are powered by the new Dailymotion API. The new API is still in beta, but some key features are already accessible.
Dailymotion Attach Videos Features
– Automatically forward videos that you own or have watched.
– Easily share a single video to a contact.

Blender exported model has reduced quality in Unity when normals applied

I know this topic comes up a lot in forums, however I have spent the last 2 hours googling it and can not find a solution for my specific problem...

I have exported this model from Blender, but when I import the model into Unity with normals set to "none" it appears as it does in Blender (see left image).

However, when I try to select import or calculate normals, it distorts the character mesh making it look less detailed and less human like (see right image).

I have tried messing with normals settings in Blender, tried changing quality settings etc. in Unity but I can not get it to look 1:1 with normals applied (obviously it needs lighting and shadows so I need it to have normals).

If anyone can provide assistance to fix this or a work around, I would really appreciate it a lot!

• Can you enable per-pixel lighting in unity? Because it looks like the usual artifacts you get from per-vertex lighting. – PeterT Aug 6 '14 at 10:19
• Hi PeterT thanks for the response. Yeh it does have per-pixel... although i'm using unity free so might not be as efficient as unity pro. That being said, the lighting doesn't have this effect other models i've imported into unity (assets that weren't created by me). – Bryan Aug 6 '14 at 11:14

Assume $$(x, y)$$ represents the position of an object and $$f(x,y)$$ is a scalar field on the $$x$$-$$y$$ plane.

Then $$\frac{\partial f}{\partial x}$$ represents the change of $$f$$ per unit length along the positive $$x$$ direction. In other words, it is the spatial rate of change of $$f$$ along the $$x$$ direction.

Similarly, derivative $$\frac{\partial f}{\partial y}$$ represents the spatial rate of change of $$f$$ along the $$y$$ direction.

For an arbitrary direction, due to the nature of displacement, the change of $$f$$ is$\delta f = \frac{\partial f}{\partial x} \delta x + \frac{\partial f}{\partial x} \delta y$when the object has finished moving $$\delta x$$ in $$x$$ direction and then $$\delta y$$ in $$y$$ direction.

Then, the spatial rate of change of $$f$$ is\begin{align} &\frac{\delta f}{\sqrt{(\delta x)^2 + (\delta y)^2}} \\ &= \frac{\partial f}{\partial x} \frac{\delta x}{\sqrt{(\delta x)^2 + (\delta y)^2}} + \frac{\partial f}{\partial x} \frac{\delta y}{\sqrt{(\delta x)^2 + (\delta y)^2}} \end{align}

For simplicity, denote the resultant displacement as $$\mathbf{v}$$:$\mathbf{v} = (\delta x, \delta y)$and define $$\nabla f(x)$$ as$\nabla f(x) = \left( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y} \right)$
Then, the change of the $$f$$ due to the displacement $$\mathbf{v}$$ is\begin{align} \left(\delta f\right)_{\mathbf{v}} &= \frac{\partial f}{\partial x} \delta x + \frac{\partial f}{\partial x} \delta y \\ &= \left(\frac{\partial f}{\partial x}, \frac{\partial f}{\partial x}\right) \cdot (\delta x, \delta y) \\ &= \left(\nabla f\right) \cdot \mathbf{v} \\ \end{align}So the spatial rate of change $$f$$ along the direction of the vector $$\mathbf{v}$$ is
\begin{align} D_{\mathbf{v}}(f) &= \frac{\left(\delta f\right)_{\mathbf{v}}}{|\mathbf{v}|} \\ &= \frac{\partial f}{\partial x} \frac{\delta x}{\sqrt{(\delta x)^2 + (\delta y)^2}} + \frac{\partial f}{\partial x} \frac{\delta y}{\sqrt{(\delta x)^2 + (\delta y)^2}} \\ &= \left(\nabla f\right) \cdot \frac{\mathbf{v}}{|\mathbf{v}|} \\ &= \left(\nabla f\right) \cdot \hat{\mathbf{v}} \\ \end{align}
$$D_{\mathbf{v}}(f)$$ is called directional derivative.

“In mathematics, the directional derivative of a multivariate differentiable function along a given vector v at a given point x intuitively represents the instantaneous rate of change of the function, moving through x with a velocity specified by v. It therefore generalizes the notion of a partial derivative, in which the rate of change is taken along one of the coordinate curves, all other coordinates being constant.”

# 注定外傳 2.4

Can it be Otherwise? 2.4 | The Beginning of Time, 7

（問：不會沒完沒了呀。只會追溯到「時間的起點」。）

（問：可能可以。所謂「時間的起點」，其實就即是「宇宙的開端」。）

（問：而物理學家知道，「字宙的開端」是「宇宙大爆炸」。所以我們知道，「時間的起點」，就是「宇宙大爆炸」。）

1. 「宇宙大爆炸」是一件事件，有一個過程，並不是時間上的「一點」，所以不算是「起點」。「宇宙大爆炸這件事的開始那刻」才算是起點。

2. 物理學家根據愛因斯坦的「廣義相對論」推斷，「宇宙開端」那一刻，開始發生的第一件事，是「宇宙大爆炸」。所以，如果「廣義相對論」不正確，「宇宙大爆炸」就未必為真。

3. 即使「廣義相對論」是可信的，普朗克時期（Planck epoch），即是開端後的頭$$10^{−43}$$秒之內，以現時的物理知識，是處理不到的。所以，物理學家推斷不到，那段時間內，發生了什麼事。
