Equal probability principle

AI Thread Summary
The discussion centers on the relationship between the "equal-probability-principle" and the "equal-a-priori-probability-postulate." The latter is recognized as a foundational assumption in statistical mechanics, stating that all accessible microscopic states of equal energy are equally likely. There is uncertainty regarding the terminology, as some participants have not encountered the term "equal-probability-principle." Clarification is sought on whether both terms refer to the same concept. Understanding these principles is essential for grasping fundamental concepts in statistical mechanics.

Hey Guys,

I have got a question.
English is not my first language.

Is the "equal-probability-principle" the same as "the equal-a-priori-probability-postulate"?

Do both names describe the same process?

Thx

I have not heard the phrase "equal-probability-principle", but I believe that the "equal-a-priori-probability-postulate" refers to the assumption in statistical mechanics that for a system in equilibrium, all reachable microscopic states of the same energy are equally probable.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
