Harold Craighead, an engineering professor at Tom's alma mater, Cornell, is working on virus-sized things. Nanoelectomechanical systems (gadgets the width of three silicon atoms) measure masses on the virus scale of 10 attograms, which is a billionth of a billionth of a gram (if my math is right). Big ideas about very tiny, very powerful things.
Before blogging became all the rage, Tom was posting book reviews and Observations (essentially early blog posts) to this site. You can find the archives below.
