My pal Jeffrey Ford sent me the link for the following YouTube video.
For his birthday, chemist Martyn Poliakoff received a periodical table of the elements 88 microns wide and 46 microns high engraved into one of his hairs. It was a gift from his buddies at the University of Nottigham's Nanotechnology and Nanoscience Center. They used a beam of gallium ions to carve the table on the hair in just seconds.
Oh, brave new world that has such tech in it.
Thanks, Jeff! It's not my birthday, but I feel that you've just given a present.
