Feast your eyes on the amazing shrinking kilogram! I poked around a bit and discovered the Bureau of Weights and Measures has some very industrial/steampunk displays, as well as an incredible amount of scientific information on their website.

Over in Barcelona, meanwhile, Casa Battló is equally stunning, but in an artistic way. Check out the detailed photos of all the rooms, and look at the outside architecture. Wow.

An exhibit featuring some full-scale replicas of Leonardo da Vinci's creations has started in San Francisco. Oooo, ahhhh! I may actually get to see this in the coming weeks.

I believe I've linked to the Gothia Gazette before, but there's always new stuff to see there.
