this video is kinda pointless
-
1400mph? where does it go at that speed?
-
It would be nice to slow the water molecules down for a moment so we can appreciate the brownian motion. A 1400 mph blur is pretty meaningless.

Mathematics in Statistics is MORE difficult than formal mathematics
just talking about getting Maximum Likelihood Estimator for a sample of 5 points involves MultiVariable Calculus in 5 dimensions or matrix algebra
In pure Math, once you declare a "Let f(x)=" you can derive what follows.
But in Statistics, nothing is given, population parameters are unkown, sample could compose of random errors, and how you sample/cluster/stratify your population complicate the equations to unmanageable level

stupid!

good question, too bad idk the answer. Let me know if you find out :P

Interesting. Obviously, this video is not very popular. But does anyone know what applications this has, and how Brownian motion applies to the normal model. What branch of statistics did Einstein use to "prove" the existence of an atom using Brownian motion?

True, it currently isn't very popular. This is an early version of a teaching module that we've been developing over the course of a year. The video was placed on YouTube as a test, with more to follow. Einstein picked up on Robert Brown's observations and ran experiments, publishing 3 papers about diffusion and properties that affect diffusion (see his 1905 publications).
