Does anybody know how to write equations in HTML? I've tried looking at the source of sites that do that, but for me, Notebook shuts down after about 1', and all of the sites that do that have really long and complicated scripts, like this site. I read on some other sites that there's a way to put forms of TeX in HTML, this would probably be the easiest, then I don't have to learn a completely different language. I find it rather strange that HTML has to resort into other languages to create equations when HTML was invented by CERN.

Does anybody here know how to create 3D computer animations? And what programs do I use to do this?

Found some more constants: Velocity of light: [math]c = 2.99793 \times 10^8m \times sec^{-1}[/math] Elementery charge: [math]e = {^{1.60219}_{4.80325} \times 10^{-19}c[/math] Electron rest mass: [math]me = 9.10956 \times 10^{-31}kg[/math] Proton rest mass: [math]mp = 1.67261 \times 10^{-27}kg[/math] Neutron rest mass: [math]mn = 1.67261 \times 10^{-27}kg[/math] Plank's constant: [math]h = 6.6262 \times 10^{-34}J \times sec[/math] Here's one I don't really understand: [math]\frac{h}{2\pi}[/math]: [math]h = 1.05459 \times 10^{-34}J \times sec[/math] Apperantly this one is [math]h[/math] too. It seems to be related to planks constant. Boltzmann constant: [math]k = 1.38062 \times 10^{23}J \times K^{-1}[/math] Avogadro constant: [math]NA = 6.02217 \times 10^{23} \times mol^{-1}[/math] Faraday constant: [math] F = 9.64867 \times 10^4C \times mol^{-1}[/math] Molar gas constant: [math] R = 8.31434J \times mol^{-1} \times K^{-1}[/math] Molar volume of ideal gas at [math]STP^{_c}: Vm = 2.24136 \times 10^{-2}m^3 \times mol^{-1}[/math] Ice point of water in absolute temperature scale (1 atm): [math]To = 273.15\degree K[/math] Mechanical equivalent of heat: [math]J = 4.184 J \times calc^{-1}[/math] Permittivity constant: [math]\Eta 0 = 8.85419 \times 10^{12}C \times c^{-1} \times m^{-1}[/math] Gravitational constant: [math]G = 6.6732 \times 10^{-11} N \times m^2 \times kg^2[/math] Acceleration of gravity: [math]g = 9.80665 m \times sec^{-2}[/math]

Latex is a rubbery substance. LaTeX is what we use to write equations. LaTeX is pronounced latech, because the X is actually the Greek capital letter chi.

I had no idea!! click above

Okay, forget the question above, I already saw the tread. And I already PM him.

What was he upgrading that he needed to take the LaTeX out?

I also edited the Wikipedia article so it gives more information. It's the same information that I have above.

The Swartzschild metric: [math]ds^2 = -(1 - \frac{r_g}{r})d(ct)^2 + \frac{1}{1 - \frac{r_g}{r}}dr^2 + r^2(d\theta^2 + \sin^2 \theta d\phi^2)[math] [math]r_g = 2Gm|c^2[/math] is the Swartzchild radius, and [math]m[/math] is the mass of the source of the field. The Swartzschild radius: [math]R_{sch} = \frac{2GM}{c^2} \thickapprox 1\frac{1}{2} \times 10^{-27}M[/math] [math]R_{sch}[/math] is the Swartzchild radius; [math]G[/math] is the gravitational constant, or [math]6.67 \times 10^{-11} N m^2 / kg^2[/math]. [math]M[/math] is the mass of the black hole. [math]c^2[/math] is the speed of light squared, or [math]8.98755 \times 10^{16}\frac{m^2}{s^2}[/math]. But anyway, the Swartzschild metric reviels a negative square root solution, along with a positive one for it's geometry. The negative square root solution in the event horizon represents a white hole, which is just a black hole running backwards in time. Apperantly they can't exist, since they violate the second law of thermodynamics. So, I guess I have no more examples of antigravity that I can think of .

Instead of sucking in matter, they push it out. I think that it would get it's matter and energy from the black hole that connects to it as a wormhole. I'll do some research on it.

Why isn't the latex working right now?

What are all of the greek letters representing? And what's wrong with the LaTeX?

If you delete your posts, what would happen if that post is quoted?

How would we detect a white hole?

That's what I ment. Is it possible that there's more anti-gravity in the universe then gravity. A kind of light matter (opposite of dark matter). Eventually dark matter would out number the light matter and cause the universe to recolapse. This would explain why the universe is expanding.

I think there should be a way to have avatars larger than the current size limit. There aren't very many pictures that fit that size limit, and when you edit it on paint, often times the scale is distorted. And I would also like to point out (for catagorization of forums) that astronomy isn't a physical science. For that, there should be a whole section entirely for earth sciences. There are also a few problems with the Latex. Every once in a while I find that I can't use Latex. I end up with a box with in x in the corner, and it has the code I used for the formula.

What more information do I need?

I understand that [math]\sin = \frac{opposite}{hypotonuse}[/math], and the other ones, but what do we use to find the leanths of opposite and hypotonuse. [math]\sin 76 \thickaprox 0.929776485[/math], and [math]\cos 76 \thickaprox 0.368124552[/math], I understand that and all the others, but what unit of mesurement do we use to find the leanths of the opposite, hypotonuse, and adjecent sides?

Many science fiction writers like the idea of anti-gravity. I was wondering how this would be possible. I know it is, because white holes have it. Scince mass bends space-time inwards, then apperently negative mass would bend space-time outwards. How could this be done?

I think clocks are more based on degrees. I havn't checked this, but I think 1' is the time it takes for the sun to move 1' across the sky. It's probably that or similar.

Here's what I found: [math]\sqrt{2}[/math], or Pythagoras' constant, is equal to about [math] 1.41421356237309504880168872420969807[/math], [math]\sqrt{3}[/math] is about [math]1.732050807568877293527446341505[/math] [math]Y \thickapprox 0.57721566490153286060651209008240243[/math] [math]\beta \thickapprox 0.70258[/math] [math]\sigma \thickapprox 4.66920160910299067185320382046620161[/math] [math]\alpha \thickapprox 2.50290787509589282228390287321821578[/math] [math]C_2 \thickapprox 0.66016181584686957392781211001455577[/math] [math]M_1 \thickapprox 0.26149721284764278375542683860869585[/math] [math]B_2 \thickapprox 1.9021605823[/math] [math]B_4 \thickapprox 0.8705883800[/math] [math]\Delta > -2.7 \times 10^{-9}[/math] [math]B'_L \thickapprox 1.08366[/math] [math]\mu \thickapprox 1.451369234883381050283968485892027[/math] [math]E_B \thickapprox 1.606695152415291763[/math] [math]\lambda \thickapprox 0.3036630029[/math] [math]\theta \thickapprox 1.30637788386308069046[/math] [math]F \thickapprox 2.8077702420[/math] [math]L \thickapprox 0.5[/math] Most of these I've never even heard of, but those are all of the constants I was able to find.

Could somebody explain to me what the perentheses mean in the something like[math]Mg(OH)_2[/math], for example? Why is the oxegen and hydrogen in the perenteses?

What are some common chemical compositions for materials used very commonly. An example would be water is [math]H_2O[/math], salt is [math]NaCl[/math]. I'm not asking things like carbon dioxide ([math]CO_2[/math]) because that's not used by the average person (besides in breathing and photosynthesis). And obviously not the ones that I said above.

Okay, then forget the question I asked above .
