1. 2012 - What do you think?

I remember Y2k, it didn't happen so we cut the power to the house and my brother ran down stairs. "Did it happen!":-p I think in 2012, when it doesn't happen I'll put a hydrolics system under his bed and start a mini earth quake when he is sleeping.
2. negative angular momentum?

I wouldn't go around saying that you have a negative angular momentum. All the negative sign indicates is the direction. So if h=-4Nms, from calculations, I would write my final anwser as, 4Nms clockwise.
3. Balance the Balls!

This is simple: Take the beam balance and put it under one end of the table to elevate one side. Then line all the balls at the elevated edge and roll them all down at the same time. The slower or faster one is the culprit.

5. Finicky Bathroom Scale

Mine does that when I accidently have it half on my bathroom rug or half off. It also happens when I don't stand on it dead center and I lean on it a bit. I wouldn't worry about it, a two pound fluxuation. If it was ten pounds, I'd throw the damn thing out. Other than that, as stated before me. To become obssesive about your weight, it will cause more harm than good. Obssesstion leads to tension, tension leads to stress, stress leads to breakdown and more weightgain I would aim to lose a pound a week. 3500 Kcal, thats about 5 hours on the tredmill for me running 7mph.
6. Is this device possible?

I don't think thats possible just by looking at the graph. The original Y-axis has peak values, if you switched that with the x for hertz. Then your hertz would have peak to peak values along the y axis. So its like your going back and forth in time and this this isn't a wave any more.
7. A Universe without Time

Personally, I think motion can continue with out the fourth dimension. If we lived in the fourth dimension, wouldn't we see all our futures and pasts at the same time? I base this on a video I saw off of tenthdimension.com. If there was no time we would move but there would be no past or future to go back to or see, thats all. But there is a dimension of time, so we can theoreticaly visit our past and future.
8. when does melting occurs?

I think melting from the inside could occur if you uniformly heated the object just up to before its melting point at a certain pressure. Then once uniformly heated, begin to cool the object on the suface. Then instananeously decrease the pressure on the object. The molecules inside which are hotter on the inside will move more freely on the outside and you might be able to get some internal melting if you don't decrease the pressure too much or cool it off too little. I think... Otherwise the only way I can imagine internal melting is if the object was made of two material, the materi
9. Science is NOT about explaining

Science to me is about having fun and to make a safer more productive world. We are all we got, and I don't think any of us would be interested in doing scientific research if it wasn't in the best interest of us or others. I will take the Miss America crown now
10. negative angular momentum?

This is correct. Say you have two vectors r= [1, 2, 0] , v= [3, 2, 0]. the k(z) component is zero because there is none, hence 2d. Now we want the cross product between r and v. To take the cross product you write i j k 1 2 0 3 2 0 Rewrite the first two lines i j k i j 1 2 0 1 2 3 2 0 3 2 Multiply diagonally from top left to bottom right, subtract when you come back multiplying from top right to
11. A basic question about Force

When I think of collision, I think energy/ momentum problem. The equations for energy and momentum are both derived from F=ma. What I take from your example is that the object being impacted doesn't move and you want to know why. The only reason that the 2nd object would not move is that if it had sufficient forces apposing this force of collision. When an object is left alone on a surface, then struck. The only force that can resist the impact is the friction force. If the friction force is sufficient enough to over come the collsion force the object won't budge. If
12. Multiple forces acting on a single point

{A bold letter represents a vector} Multiple Forces on an object: Ft=$\sum$F If there is more than one force acting on an object, a single resultant force can be used to express their effect. If you know all the forces and their direction, add them up vectorially. Adding vectors is not the same as adding magnitudes (or plane old numbers) There is no need to go through an entire lecture on vectors, I'm sure you can find that online. But a simple example of vector addition is: y | | (5N) -> [_] <-(-6N) |___________________
13. HELP! I need a time machine.

At the University of Connecticut a professor, Dr. Ronald L. Mallett, has theoretically designed a way to travel though time. The university thinks its the real deal and is currently trying to get funding to build and test it. A link to one of his sites is here with two technical papers: http://www.phys.uconn.edu/~mallett/main/time_travel.htm Also his email taken off the University's Physics Department webpage is: rlmallett@aol.com I never met him, but I've passed his office a few times going to physics lab .
14. containing antimatter

With your design, how do you get the positrons out safely?
