The world's tiniest periodic table

Tonight, I got to meet Martyn Poliakoff — the fabulously frizzy-haired University of Nottingham chemist who you might recognize from a series of awesome videos about the periodic table that Xeni first blogged about back in 2008.

This is his business card.

It's a microscope image of the world's tiniest periodic table, which Poliakoff's friends inscribed on a strand of his own hair as a birthday gift in 2010. The hair, which Poliakoff keeps in a glass vial, has earned him a spot in The Guinness Book of World Records.
