The Hobby of Energy Secretary Steven Chu

quanminoan writes "Nobel Laureate and US Secretary of Energy Steven Chu has continued to publish even while in federal office. While previous research topics include gravitational redshift, Chu has coauthored a paper entitled 'Subnanometre single-molecule localization registration and distance measurements' which discusses a way to optically image objects as small as 0.5 nm — a major step down from the previous limit of 10 nm. Chu does this in his free time, claiming 'I just consider it my equivalent of ... vegging out in front of the TV.'"
