Martyn Poliakoff, chemistry professor at the University of Nottingham and owner of the best head of hair in science, has a video today exploring the properties of aluminum (or as chemists call it, "aluminium"). There are a lot of fascinating facts in here, but most interesting is a special periodic chart showing all the elements like usual, but with the size of each box adjusted to reflect their relative abundance. Apparently, there is more aluminum than iron on this planet!
