Heat: The considerable kinetic and potential energy possessed by an orbiting spacecraft must be lost during re-entry. As the atmosphere decelerates the spacecraft, the energy is converted into a great deal of heat. This heat must be tolerated and/or minimised. The heat can be tolerated by using...
physics is interesting IF U UNDERSTAND IT. seriously if u dont then well i can see how it could be boring. But since i do understand da physics i find it hella interesting although seems to have so much historical and theory stuff for my liking needs more maths
ok pretty much conduction band is the level where an electron will be free from the atom thus able to move freely amongst crytal.
p and n type refer to http://community.boredofstudies.org/showthread.php?t=190299 go to my post then go to website lol
yeah essentially physics is just concepts. U learn and understand these its not hard to build on them. I mean i guess not that much to remember if u know the concepts which are developed throughtout each of the topics.
for number one difference occurs within the void area.

scroll down it just means
for n type they gain essentially another level to accept electrons
for p type another level to accept holes
