I am an admitted smartphone convert. After I was dropped into Salt Lake City needing a Wal-Mart, Home Depot, Lowe's, Office Depot, a bookstore, and a laundromat in the span of a few hours - all of which I found with no problems whatsoever - I don't think I can ever go back to not having the world's knowledge at my fingertips.
Admittedly I wasn't aware of just how many rare earth metals were found in my smartphone, however. Thanks to Compound Interest, now I know.
Compound Interest is a British blog through which Andy Brunning, a chemistry teacher with a flair for graphic design, posts outstanding chemistry-themed infographics.
