Money and Science
Writing grants all the time (another deadline coming Monday, yikes) made me think about money and science, but in a rather oblique way: coins and notes commemorating scientists and scientific achievements. While looking for examples, I found that Alex Pasternack from Motherboard.TV has done a really nice and thorough job already. So have a look, really cool collection of notes & coins commemorating scientists. If you know of any other science-inspired currency, please link to a pic in the comments.
