The Hobby of Energy Secretary Steven Chu

quanminoan writes: Nobel Laureate and United States Secretary of Energy Steven Chu (http://en.wikipedia.org/wiki/Steven_Chu) has continued to publish even while in office. While previous research topics include gravitational redshift (http://www.nature.com/nature/journal/v463/n7283/full/nature08776.html), 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 large 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".
