There is an interesting article about Gregg Berman, who received a PhD in particle physics from Princeton about 20 years ago, who is heading the investigation into the stock-market free fall on May 6:
In investigating the crash, Mr. Berman says he finds himself in a position similar to his physics work 20 years ago, when he was collecting huge amounts of data and comparing the competing views of many laboratories on a question dividing particle physics — whether the neutrino, one of the least known and most common elementary particles, actually had mass.
Particle physicists sometimes show up in surprising places.
