I read this as "given any distribution which is symmetric about zero, the distribution mean will be zero". That is a true statement...

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...

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...

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...

That tells us the sample size. It does not tell us the distribution from which the samples are drawn. Google ("what is the distribution...

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...

If you have one particle, the components of the velocity vector at some chosen time are not isotropic. The particle is [almost...

From the premise that the velocity distribution is isotropic.

That may be the idea that he is pursuing. But the argument he made does not use the premise that the velocities are uniformly...

How can we infer a uniform distribution from a pair of samples that are not?

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...

So, again, where did those specific numbers come from?
