Hello, There are two questions in my original e-mail: The second one - about temperature distribution as function of time and distance from heat source is more or less clear, but if someone can recommend where I can read about relevant math it would be great. The first question actually is...

Yes, but before the system stabilised? During this period distribution of temperature as function of time and distance from 0 can be different.

Usually it is said that loss of heat through a chunk of material because of conduction is proportional to difference in temperature and inversely proportional to thickness of material. E.g. if I got a wall to ΔQ = K*S*ΔT/D. where ΔQ - is energy flow through material. K - constant characteristic...

Ok, that helps. I got some understanding of how planets evolve and I brought this example of planets in order to illustrate a contradiction which I was unable to explain. Of course planets are spherical not because it is a law of nature, but because under conditions you mentioned they will...

Hello, from time to time I got question in physics for which I can't readily find answers. I hope I can get answers here. Here is my current one: Usually textbooks state that space contracts in direction parallel to direction of motion. It sounds strange, because time changes uniformly, and as I...
