jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.I read this as "given any distribution which is symmetric about zero, the distribution mean will be zero". That is a true statement... -
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.1. Google AI is not an acceptable reference. [See the rules here. Search for "ChatGPT and AI-generated text"] 2. If Google AI says this...

I'd like to add this to what @jbriggs444 has said. No. You are wrong! Try working through the following carefully. Step-1... -
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.How is it possible? Why should it not be possible? Why the surprise? It is very difficult to respond to an open ended question like...

@Mike_bb, can I throw this in... Suppose you have ten 6-sided dice, each marked with the values: -3, -2, -1, +1, +2, +3. You throw...
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.But what are you integrating over? Are you "integrating" over a small finite sample (e.g. [-6, 1, 2, 3]) That would be ##\frac{(-6)^2...
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.That tells us the sample size. It does not tell us the distribution from which the samples are drawn. Google ("what is the distribution...

jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.The x and y components of some set of velocities, yes? What set of velocities? You have claimed that the components are "uniformly...

When the ellipses (...) is used to continue a sequence, the author's intent is obvious because the terms in the sequence form a pattern...

jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.If you have one particle, the components of the velocity vector at some chosen time are not isotropic. The particle is [almost...
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.From the premise that the velocity distribution is isotropic.
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.That may be the idea that he is pursuing. But the argument he made does not use the premise that the velocities are uniformly...
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.How can we infer a uniform distribution from a pair of samples that are not?
-
jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.Technically the quoted passage is false. It is an argument, not a valid proof. The first error is minor. The author says that if the...

jbriggs444 replied to the thread I What does equiprobable mean in the context of thermal motion?.So, again, where did those specific numbers come from?
