Yo! Anyone know of any free font compatible with Word (or that comes with Word!) that has the goddam electric field symbol in it? Whoever came up with that sign had an irrational hatred of word processors.

have not seen this anywhere I've looked, anyone know?

Has anyone a derivation at hand of the Christoffel symbol by permuting of indices in a free fall system? Roland

For a bonus question my physics teacher asked if anyone knew why we use the letter "Q" in terms of heat. If anyone can explain the origin of why we use Q for the symbol your response would be greatly appreciated. Thanks

I am working on some homework that I already handed in, but I can't get one of the problems. The fourth problem on the HW was to prove the forms of (-1/p), (2/p), (3/p), (-5/p), and (7/p). I did this for -1 and 2 using the quadratic residues and generalizing a form for them. for 3 and 7 i...

I'm having trouble with the following VHDL code: library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity circuit is port (a, b, c: in std_logic; f1, f2, f3, f4, f5, f6: out std_logic); end circuit; architecture...

There is a symbol that looks like this http://mathworld.wolfram.com/nimg268.gif The symbol is like a line that is curved on both ends. Thanks in advance!

What's that symbol? Today we've studied in the electrodynamique an affector named dalamperes affector defined as: \nabla^2 - \frac{1}{c^2}\cdot\frac{\partial^2}{\partial t^2} c is the speed of light in vacuum, t is time, \nabla is hameltons affector, HERE IS THE QUESTION: What's the...

I'm trying to put an Angstrom symbol into a microsoft Word document. It's a capital A with a little circle over it. But what is that character called? It's not a greek symbol, I don't think. Does anyone know how to put it in Microsoft Equation Editor, or even what it's called so I can...

does anyone know what the symbol that looks like a tall pi means?

Hi, I have met a problem, that is how to prove transformation law for Christoffel symbol of first kind. I have read books about that, but many of them just state: cyclic permutation of the 3 indices and substitution. When I tried to work out, I could not elimate some terms... Can anyone show...

What is the actual name for the integral symbol? I know it was first used by Leibniz, but did he actually call it anything...? It's really hard trying to convince my friends the integral symbol is the sexiest thing ever invented, when I don't even know her true name. :blushing:

4πε0r^2 Thats 4pi (backwards 3 0) R squared. I forget what the backwards 3 o stands for can someone help me out

"Enigma" Is this the correct name for a math symbol that represents the phrase, "There exists"? I believe it's something like an 'E'.

hellooooooooooo everybody ! can anyone please prove the following : 0! = 1 cheers abc

Well I have this leftwards arrow in my book describing the solution to a logarithmic function and I've not seen it thus far and (if I was ever introduced to it) have since forgot what it means! When asked to find log(3)9 3^x = 9 3^x = 3^2 <--x = 2 log(3)9 = 2 I'm not sure what the...

"Symbol" html on Netscape and Explorer Apparently my recently installed Netscape 7.2 does not translate to Greek my website html symbol code, where Explorer had. Why is this so, and how can I either make Netscape translate or choose Explorer as my default browser for executing my FTP document...

On page 34 of General Relativity, Robert Wald, the author refers to the Christoffel symbol as a tensor of rank (1,2). That whole derivation that led to that is quite involved so I don't quite understand how Wald can say that the Christoffel symbols are tensors since normally one does not refer...

The USA is sending 400 armed soldiers to the Olympics. Yay. http://www.news.com.au/common/story_page/0,4057,10208766%255E28793,00.html

Hi people I study on image processing and fuzzy logic. When I working on histogram normalization, I saw an equation which includes a symbol 'U' letter. On the bottom of the 'U' (m=1) and on the top of the 'U' (K) is written. And i want to learn what its (U) mean. Thanks in advance...

Anyone knows why the symbol c was chosen to represent the speed of light in vacuum? Or is there no reason really?

When you are solving exact differential equations you want to do the opposite of partial differentiation, And when you apply Leibniz's integration I have seen an example were there was an integral symbol (with respect to x) and they treated the other variable as a constant. Is the notation...

I find myself continually referring to this: \int as the 'integral-symbol-thingy'. Does it have a name? I asked my math teacher; he said it has a name but he couldn't remember it.

Under the list of math symbols, nabla doesn't show up (the upside down triangle). Why is that? I just use &#9660 instead.

I was wondering how it could be possible to make some other ("sci-fi" thinking, I know...) intelligent lifeform aware of human knowledge and scientific status by means of a symbol or something - assuming of course that this other lifeform can interpret two-dimensional vector graphics as a means...

This is the first thread in what may or may not be a series, depending on logical topics that I think need to be addressed. I want people to understand the fallacies of certain "word games" so they can stop wasting time with fallacioius arguments. Let's start with what I call symbol...
