Not For Math-Phobes

First, an interesting (lengthy) article on problems with statistics in research here:

On a related and slightly less-technical note, just finished reading Jason Rosenhouse's wonderful 2009 volume, "The Monty Hall Problem," devoted entirely to the "Monty Hall" problem from mathematics (one of the most intriguing, well-covered/debated probability problems oft-presented

The Polymath Project

 

The Polymath Project uses the 'Net to prove complex mathematical theorems (faster than they could be solved by individuals working apart). Fascinating concept... read all about it:
