In American football, it seems that some people would say:     He caught a pass.   To my knowledge, a "pass" is an action.  So, the sentence would translate to:     He caught an action.     Is my analysis wrong?
The context is soccer (association football) and the sentence in question is:       The forward received the ball from the midfielder's pass.     I have already ask about this  and received alot of good answers, and I tried to leave it at that.  But then the World Cup 2014 is upon us, and I am starting to have doubts about this football usage of "from", to the point that I have semi-nightmares about it.  The use of "from" in the football example continues to bother me.  I seem to disagree (subconsciously) about how a ball (physical object) could be "from" a pass (action) unless that action creates that object.       Some people were hit by debris from the explosion.   The use of "from" in "debris from the explosion" makes excellent sense to me, because the explosion does create the debris.  But in soccer/football, the ball cannot possibly be "created" by a pass.    Is there any non-football usage of "from" similar to my football example sentence?
What is the number of invertible $n\times n$ matrices in $\operatorname{GL}_n(F)$? $F$ is a finite field of order $q$. What is the size of $\operatorname{GL}_n(F)$ ?  I am reading Dummit and Foote "Abstract Algebra".  The following formula is given:  $(q^n - 1)(q^n - q)\cdots(q^n - q^{n-1})$.  The case for $n = 1$ is trivial.  I understand that for $n = 2$  the first row of the matrix can be any ordered pair of field elements except for $0,0$. and the second row can be any ordered pair of field elements that is not a multiple of the first row.  So for $n = 2$  there are $(q^n - 1)(q^n - q)$ invertible matrices.  For $n\geq 3$, I cannot seem to understand why  the formula works.  I have looked at Sloane's OEIS A002884.  I have also constructed and stared at a list of all $168$ $3\times 3$ invertible matrices over $GF(2)$.  I would most appreciate a concrete and detailed explanation of how say $(2^3 - 1)(2^3 - 2)(2^3 - 2^2)$ counts these $168$ matrices. pgfplots from file: search path, looking for \graphicspath equivalent What happens if you use a drone to build a building while he's carrying minerals? Kind of a basic question, but what happens? Do you lose it? Does it count as harvested?  In a similar fashion, what happens when a drone/scv/probe goes harvesting gas when he's holding a mineral? What is the best way to execute a script when entering into a directory? When I move into a new directory I would like bash to execute the projectSettings.bash script much like RVM does.

How to tell if a  tag failed to load I'm dynamically adding &lt;script&gt; tags to a page's &lt;head&gt;, and I'd like to be able to tell whether the loading failed in some way -- a 404, a script error in the loaded script, whatever.  In Firefox, this works:  var script_tag = document.createElement('script'); script_tag.setAttribute('type', 'text/javascript'); script_tag.setAttribute('src', 'http://fail.org/nonexistant.js'); script_tag.onerror = function() { alert("Loading failed!"); } document.getElementsByTagName('head')[0].appendChild(script_tag);   However, this doesn't work in IE or Safari.  Does anyone know of a way to make this work in browsers other than Firefox?  (I don't think a solution that requires placing special code within the .js files is a good one. It's inelegant and inflexible.) What are the basics needed to learn quantum computing? I was very inspired by Michio Kaku's  on the possibilities of quantum computing and also listening to Talia Gershon's  on it.   As I come from a business &amp; analytics background, what materials can I begin exploring to prepare to learn more about the field of quantum computing? Eg. what would I need to study to understand Peter Shor's algorithm,  on physics, etc. Encrypting a key with the same key, for instance using AES I am new to crypto and trying to understand if it would be insecure to use a cipher such as AES to encrypt a key with the same key. If it is insecure, then why would it be insecure?  Basically, something like this:  encrypt(key, key)   What happens when both key and message are the same (128 bits)?  The obvious question would be why would I want to do that. If I have a secure channel to send the key, why encrypt it? My question is more for understanding.

In a  2.0 C# application I use the following code to detect the operating system platform:  string os_platform = System.Environment.OSVersion.Platform.ToString();   This returns "Win32NT". The problem is that it returns "Win32NT" even when running on Windows Vista 64-bit.  Is there any other method to know the correct platform (32&nbsp;or 64&nbsp;bit)?  Note that it should also detect 64&nbsp;bit when run as a 32&nbsp;bit application on Windows 64&nbsp;bit. Why java classes do not inherit annotations from implemented interfaces?

The force of gravity is constantly being applied to an orbiting object.  And therefore the object is constantly accelerating.  Why doesn't gravity eventually "win" over the object's momentum, like a force such as friction eventually slows down a car that runs out of gas?  I understand (I think) how relativity explains it, but how does Newtonian mechanics explain it? Prove the inequality $\frac{a}{c+a-b}+\frac{b}{a+b-c}+\frac{c}{b+c-a}\ge{3}$ Why doesn't Zorn's lemma apply to $[0,1)$? When I measure a 9V DC wall adapter power supply with a multimeter it shows 11.8V. When connected to my board this voltage lowers to 10V. Is this normal? Should I be afraid of toasting my  supplied board when using this adapter?  Edit: This regulator accepts up to 12V inputs. So that will be no problem. A second "9V" adapter yields 15V to the multimeter. Will this one burn my circuit? How is MSE divided by $\sigma^2$ always a chi-square distribution? Working in a group blender project Me and my team are new to blender, we are now planning for a small project. What I want to ask here are some questions regarding the team work:   We use git for version control in web projects, Is there any special version control for blender project. Creating object of each file and integrating in the project is one way we saw to complete the project. But is there any good way to work in the group?   Please tell us from your experience what might be the best way to work together in a group blender project.
