using the poisson distribution to approximate the binomial distribution

Normal distributions for people with a flair for linear algebra :).

Evidence of a surprising mathematical pattern (Zipf Distribution) in both the relative populations of cities and the calories burned by mice.

That's very cool. I hadn't known anything about the Zipf Distribution before.

Whoa. I guess humans are more in tune with their surroundings than we think.

I spiffed up and posted the GeoGebra worksheet if you're interested.

Bertrand's Paradox is a question in continuous probability that shows the perils of uniformly distributed variables. The question is simple: given a random chord in a circle, what's the probability that it's longer than the side length of an equilateral triangle inscribed in that circle?

What's the length of a random chord in a circle? It turns out that even if you try to distribute the chord uniformly there is an ambiguity.

Mandlebrot argues that markets do not follow a normal distribution. An interesting book from the man behind the Mandlebrot set.

thanks for this. Dr. Mandlebrot seems to be always ahead of his time.

the data, pure and simple
