"We've seen the Torah inscribed on a surface the size of a pin, and the atomic pen making inroads into even more impressive feats, but tiny writing never ceases to amaze us. Now, it seems, the entire periodic table of the elements has been scribed onto a single hair -- that of Martyn Poliakoff, Professor of Chemistry at the University of Nottingham. The project involved magnifying the hair under an electron microscope, and 'writing' on it with ions using an ion beam writer to imprint the entire table of elements onto the hair. As you'll see in the video after the break, the results are quite impressive albeit very small."^^<http://www.w3.org/2001/XMLSchema#string>
