I read the article, I didn't decide to get another Ph. D. (Although physics would take a bit less time, certainly...)

But it seems to me that the results demonstrate that the Brownian-like motion is imprecise for determining the actual motion of particles. This does not contradict what I said. The math behind Brownian motion is solid.

The math behind Brownian motion is solid.

I'm curious as to what math is necessary to say that particles move and collide randomly?
