One of the blogs I hyped at the science blogging panel at Worldcon was Built on Facts, Matt Springer’s blog explaining introductory physics concepts. You might not think that you want to read a blog that goes through freshman physics problems in detail– I would’ve been dubious on the concept, had you explained it to me that way– but it’s really excellent stuff.
He’s recently completed a series of posts on Maxwell’s Equations, with one post for each of the four equations, plus one bringing them all together: Gauss’s Law for Magnetism, Gauss’s Law for Electricity, Faraday’s Law, and the Ampere-Maxwell Law (the only one Maxwell added anything to), and Maxwell’s Equations & Light. These posts are excellent, concise, readable introductions to these equations and why they matter. Somebody get this kid a textbook-writing contract.
With those posts as a resource, this is an excellent time for a Dorky Poll:
I know they’re all lovely equations, but you really have to choose only one of them to be your favorite. Unless you have multiple computers, and vote multiple times.
