I was reading the Library article on quadratic equations--I'm not sure why--and noticed that a proof of the quadratic formula is not offered. Here is a proof that depresses the quadratic into an equation of the form ax²=b, where a and b are some arbitrary constants.

For the general quadratic equation ax²+bx+c=0:

Let [tex]x=y-\frac{b}{2a}[/tex]
[tex]a \left(y-\frac{b}{2a} \right)^2 +b\left(y-\frac{b}{2a}\right)+c=0[/tex]
Expand [tex]\left(y-\frac{b}{2a}\right)^2[/tex]...

I just upgraded from Mathtype 5.0 to Mathtype 6.6 . I looked that the translator option and I see "Physics Forum."

With Mathtype:
[itex]{e^{ix}} = \cos x + i\sin x[/itex]

God has answered my prayers.

why do we idolize moviestars, sportstars, and celebrities? and why do we go to any lengths to defend them in heated arguments, appreciate their slightest gestures, find class and style in their smallest movements, go around dishing amazing facts about them, try to know the minutest details of their life, well practically worship them? it probably is our subconscious acceptance of the fact that they have, in a particular field, achieved a level which we can only dream of. i repeat.our fanaticism...

Well then.....ummmm
never had a blog about physics..never had a blog AT ALL!!!! so hi, i like food and i like science-ALOT

The accepted wisdom is that the universe used to be made up OF A PERFECT LIQUID (quark-gluon plasma) and that because of the high temperatures and high densities and the expansion of the universe that the process was irreversible.
It would be impossible to make protons go back to A PERFECT LIQUID (quark-gluon plasma). THOSE CONDITIONS WOULD BE IMPOSSIBLE TO RECREATE.

Now we know that is wrong.
We can reverse the process and get A PERFECT LIQUID (quark-gluon plasma)....
