#1. Ethan Siegel
Blog: Starts With a Bang!
Ethan Siegel truly has a gift. He has the ability to make extremely complex topics -- from astronomy and particle physics to mechanics and relativity -- understandable to the average person. Siegel's unmatched ability to describe the nearly indecipherable made him an easy choice for #1. Apparently, NASA agrees, as Siegel has just been hired to write astronomy club articles for them. Regardless of the difficulty of the topic, be it pre-Big Bang inflation, interpretations of quantum mechanics, or a detailed explanation of the Higgs boson, we can't help but feel a little smarter every time we read Siegel's blog. And honestly, that may be the best compliment a science writer could ask for.
