  The link on that page doesn't resolve, nor is that what the short writeup about the undergraduate work is about. Most of what the statisticians conclude about the physics seems to be based on poor experimental design. measuring human biases in coin flips seems to be a bit off the point-- you'd do better building a machine that emulates humans better, than to take two people and collect a large number of samples between them. Put another way: when somebody builds a robot and collections the results of thousands of coin tosses, picking two undergrads at stanford and using their physical mechanisms does not advance any useful scientific argument about bias in coin flipping. It just muddles reality with advanced stats on heavily biased data.
