My university lecturer is very new, his lectures and notes are hard to follow and understand. He was a replacement to the old solid state physics lecturer and has designed the module from scratch, so it is unpolished in its current form. Can you please suggest some alternative resources...

thank you guys. that's very helpful!

Two particles, one with more kinetic energy, one with less. So basically it is more likely for the more energetic particle to pass larger amount of energy to the less energetic particle than the situation reversed.

My intuition tells me exactly the same thing as well. But why energy like to be evenly distributed? This goes back to the old question. Because energy is more distributed or spread out when total entropy increase.

Im not satisfied with the answer: that's just what it is... Because it kinda doesn't explain anything. Please help me, anyone?

For proving the natural number, e. (1+1/n)^n As n approches infinite, (1+1/n)^n ----> e However, wouldn't it become one as n becomes infinite? (1+1/n)^n=(1+0)^n=1 Could anyone explain this to me please!

in an energy level of atom, electron can be found here or there by chance. I presume that the location electron can be observed with 100% accuracy. At time A, the electron is found at location X. if, let's say there is a parallel universe, where everything are the same, the energy, the time...

thanks guys!

thanks

What are the ways to build electric circuits without using semiconductors? thx

what are the alternatives to silicon chip?

OK... how does the object do not go beyond the speed of light given that there is infinite lengths for acceleration?

why? please explain. also, what about a wrap drive?

If a a object is falling in a gravity field with infinitly long radius. can it eventually travel faster than the speed of light?
