Hello everybody, from a non-relativistic point of view , taking into account an N-point particle isolated system, in which interacting with each others in principle we can describe the time-evolution of the system, defined by hamilton's equations: Where H is the total internal energy of the...

I think I wrote it in the wrong section. I mean, maybe the 'Atomic, solid state anch comp. physics' section should be better, but I don't know how to move the post.

Hello , i have some troubles with basics concepts of statistical mechanics. I feel confortable with the general idea of an Ensamble, a collection of copies of the physical system which differs from each other due to microscopic differences and having the same macroscopic behavior. I'm ok also...

Hello everybody, i have some troubles with the interpretation of curl in 2D/3D space. I was looking for a better understanding of Curl, watching this video generally curl represents the 'amount' of local rotation in a vector field, point by point. If we think at the 2D vector field described...

There's still something that I don't understand: If you consider that situation as a 0% efficient machine the whole calories burnt should convert to heat. But if you imagine that you lift the weight doing a certain amount of motion against gravity, you should conclude that efficiency is not...

Everybody experiments fatigue holding a weight, and almost everybody knows that points of applications of the involved forces don't move. We also know that we cannot use the standard equation of the conservation of energy ( ΔK + ΔU = Wext ) because the system (Body+weight) is composed by...

Hi eveybody, I'm glad to be part of this community. Cheers from Italy! H.M.
