Chi Square Test: Interpretation of (O-E)^2/E
In this video, I try to show how the (O-E)^2/E calculation in a chi-squared test is connected the sum of squared z-scores, something visually closer to the definition of a chi-squared distribution. The video should be understandable to new students of stats and more advanced ones.

The Universal Relation Between Exponents in First-Passage Percolation - Sourav Chatterjee
Sourav Chatterjee Courant Institute; NYU October 18, 2011 It has been conjectured in numerous physics papers that in ordinary first-passage percolation on integer lattices, the fluctuation exponent \chi and the wandering exponent \xi are related through the universal relation \chi=2\xi -1,
