I'm watching The Elegant Universe and frankly, when they started talking about the need for several extra dimensions in order to have String Theory work, they lost me. It sounds like they're creating their own proof, 'strings' as well as these extra dimensions, which....surprise,surprise.....can never be observed or have their existance disproven....

I dunno, I think it sounds like hoke-um to me...

Say you had a sphere with a totally reflective coating on the inside that was like a one-way mirror, light could pass one way, not the other. If you shine a light into it, wouldn't the light just keep bouncing around inside? There would be nothing there to absorb the light.

The man releases the object at a height of 1.2 m, it rises another .3m to a peak height of 1.5m, then hits the gate at a height of .3m from the ground. The horizontal distance between the point of release of the object and the gate is 7m. With what force does the 2.7kg object hit the gate? Thank you for any help calculating this. The only ballpark answer I could come up with (for being an extremely Physics-handicapped person) is 104.5 pound/ft. This is from an event that actually happened, with someone throwing an object and damaging our gate; said person does not believe a 2.7 kg object could do this being thrown from the given distance.

For example, I can only barely smell the perfume that I've put on after several minutes pass. Sometimes as I'm getting ready, I wonder if I have already put perfume on or not. Seems like I should be able to tell by smelling it but I can't. The perfume will dissipate but that doesn't explain how hours later, someone may compliment my perfume. It must still be there even though I can't smell it at all.

Another example is how you can walk into a room and be overwhelmed by a smell but then after a minute or two you get "used to it". (Think of cookies baking instead of walking into a restroom.) You might completely forget about the smell that was so strong to you earlier until someone else walks into the room and they comment on the smell.
