Book
Finished "Mathematical Mountaintops", which was really good.
Skimmed "The Pale Blue Dot" by Carl Sagan, which had too much I already knew.
Finished "The Equation That Couldn't Be Solved: How Mathematical Genius Discovered the Language of Symmetry" which was a bit scattered, and only skimmed over the more interesting theoretical bits. I liked some of the historical bits though, and it did convince me that group theory is very interesting and I need to know more.
