If you're looking for good graduate programs that don't require the GRE, than you should check out West Virginia University. I am currently an undergraduate there, and know that we do not require a GRE score. We have one of the top plasma physics and condensed matter physics programs in the...

Yes. The mass is generally the same for the matter-antimatter pairs. In fact, everything is the same, except for the charge and spin. They are, of course, opposite.

Maybe the inability to see it is why we think it isn't there. Perhaps there is some way to assume what it is SUPPOSED to be, and we can see if there is any difference between that and what we experimentally see. Maybe the difference is gravity. Because gravity is very weak anyway, the...

Every other force attracts and repels, gravity does not. Gravity only attracts. This is assymmetrical. We like to assume things that are not symmetrical are wrong. Why do we not assume this is wrong? Is there any possible way gravity could be repulsive? I know there is staggering amounts of...

Have you guys done the conservation of energy theorem yet in class? If so, you can find this by realizing that U1 + K1 + W = U2 + K2

The initial velocity of the hammer will be the same as the final velocity of the hammer right before it hits. (unless you are accounting for lost energy when it hits)

Thanks

Today in physics class we talked of Gravitational Potential Energy. We talked about how K1 + U1 = K2 + U2 etc etc. But the idea of potential energy makes no sense to me. They say if you lift something off of the ground I.E. a phone. If i lift the phone up and put it on a table, the energy I...

Experimental HCl that you usually use in labs, is relatively not dangerous, however don't get it on your clothes.

We had this awesome mixture lab which he gave to us the first day of my first year of chemistry in HS. It was a solid mixture of wood chips, iron bits, benzoic acid, salt, and sand. He said, Separate this.It was loads of fun. Of course, you use a magnet to remove the iron. Put it in water and...

Meh, what he says makes sense.

What about mine! I got the coolest game ever.

If you're taking Calc I I am assuming you're a freshman? In which case if you failed one class, and for the next 4 years get A's, they will probably consider the F a fluke, and if you explain in a letter, you got as good a shot as anyone

I've seen mol abbreviated at m before, but never m with a bar over it. You could be integrating something possibly?
