I am looking for some software that will help me to visulize my concepts in 3-D. eg. geometrical shapes, lattices, waves, molecules, structures etc.
I have seen many such 3-D images on the web and would like to know which software creates them. Animation of shapes like waves etc. would be great.
So if you know of such software do let me know.

It seems to me that hot water has to lose heat until it reaches 32F (0 Celsius) before it begins to freeze. The only logical explanation I can think of is if two identical metal ice cube trays were filled with hot water in one and cold water in the other and placed in a freezer that had a layer of frost on top of the coils the tray with hot water would melt the frost and the metal tray would get better surface contact with the coils while the tray with cold water would sit on top of the frost which would be like an insulator. Any comments?

I'm working on a physics problem, which seems to be a "changing y" problem. However, it feels like something is missing from the question...can someone point it out to me? Here's the original question:

"When Babe Ruth hit a homer over the 12 m high right field fence 100m from home plate, roughly what was the minimum speed of the ball when it left the bat? Asume the ball was hit 1.0 m above the ground and its path initially made a 40 degree angle with the ground."

IF this was a changing Y problem, I would assume: Dy = 11m, Dx = 100m, Initial Vx = Initial V[(cos400], Initial Vy = Initial V[(sin400], a = -9.8 m/s^2.

Is there something I'm just missing? Please help!

I make my daily cups of tea in a microwave oven. Heat water for 2 and half minutes. Take out the cup. Dip my teabag. Cool a bit, and drink.

Sometimes, even though the water is just 'bubbling' when I take the cup out of the microwave oven, the minute I dip in my teabag, the water bubbles up furiously, even overflowing the cup last night.

Why does this happen? Is there an agitation of water molecules by the microwave radiation that gets aggravated (or resonates) when tea bags are dipped in?

Or is it because of air pockets within the tea bag itself that are released and heated to steam and released?

Or is there another explanation?

Thanks for your time in helping me explain this curious phenomenon.

This has been on my mind for a few months. I watched a documentary on the Science Channel 6 or 7 months ago. They talked about an universal equation that can solve all problems concerning physics. So I was wondering if it can be crack, and have any of you cracked it??

I dont think time travel would be viable only because of the fact that anyone traveling back in time would risk spreading desease like the spanish did to the indians in early america. The same goes for traveling forward in time. The traveler wouldnt be immune to even the common cold in the future but thats just my opinion. whats yours.
