These are illustrations that explain principals of physics, some quite famous. Accompanying each are a very short chapter describing the idea or the experiment. A picture is often worth 1000 words, but even that amount is insufficient to cover complex ideas such as the Higgs boson.

A mini-biographical sketch is usually also included, and these are welcome. While I appreciate the visual, the whole collection came across as so-so to me. I think it would have been better as a web-based series, with abundant links to additional information. 2½ stars.
