Sketchy Science
Welcome to Sketchy Science. The blog that attempts to explain some of the universe's coolest things in the most comprehensible way possible. We (Steve Kux and Geoff Lee) are just a couple of former students who never got tired of researching, writing, and doodling in the margins. We are here to explain all things science and we will happily consider requests for articles. Send your ideas, feedback, and inevitable corrections to: sketchyscienceblog@gmail.com
