Theodore Gray's interactive periodic table isn't the only periodic table online -- another one was posted to MeFi last month -- but I think it's the most gorgeous, informative, and ambitious periodic table I've ever seen, featuring actual samples of most of the elements and their practical uses, a fascinating display of uranium isotopes, and explosive "sodium party" videos and more from Gray's many years of obsession with the elements.

"Gold is one of the few elements you can find just lying on the ground. This one-ounce pure gold nugget was found in Alaska around 1890 by Hogamorth Marion, while on a trip to sell shoes to Eskimoes. Seriously."

An interactive periodical table.

There may be many more but they haven't been dis-coh-vahd As of 1959, the news of 102 elements had come to Harvard (a modern remake would have to cram in 13 more.) There's more than one way to look at them, like spiral, rotating, illustrated, sub-atomic, symmetric, or forward-looking. Been there? Done That? Get the t-shirt.

The Periodic Table Table now has its own, newly updated website. This had made the rounds on various websites when it was a mere set of construction photos on a bandwidth -constrained site. This is now much better.
