Oklo Fossil Reactors

In 1972 in Oklo, Gabon, while mining for uranium a very strange thing was discovered: the fossilized remains of a naturally occuring nuclear reactor. Later several other similar reactors were discovered, each dating back about two billion years. This is one of the few sites I've been able to find with explanations of the phenomenon and photographs of the site.

2020 Update: That site is dead, but there are lots of sites about the Oklo Natural Fission Reactors now. And there's a start-up company named Oklo trying to make small fission reactors.

2020 Update: That site seems to have gone away, but there is a different site related to Automats at theautomat.com, just don't expect recipes.

Worldwide Vintage Postcards

A huge collection of old postcards, some used, some not, apparently all for sale. It would be nicer if the pictures were larger, but a fine collection.
