Why Didn't I Think of That?
Coat hangers. Sliced bread. Bottled water. These simple yet successful inventions are among the 101 chronicled in Anthony Rubino Jr.'s cleverly funny Why Didn't I Think of That? ($10). This 224-page book looks at the complexity behind these common goods, while offering up tons of questionably useful trivia and imparting some possibly needed advice to future inventors. You won't find this one listed in the academic section, but it's perfectly fine for light coffee table or bathroom break reading.
