A close look at chemical elements, the basic building blocks of the universe. Where do we get them, what do we use them for and how do they fit into the economy?
BBC is running this very cool audio series that dedicates 40 minutes each to every element in the periodic table, specifically looking at how it fits into our economy. They are doing one element a week and started last November, so are about 1/2 way through the periodic table now.
So far all the episodes I’ve managed to randomly catch on WAMC have been great. But if you want the complete set, they’ve got it loaded up as a podcast as well. Definitely worth your time.
