Last July I reviewed a fascinating book: The Geek Atlas: 128 Places Where Science and Technology Come Alive.

Author John Graham-Cumming compiled this atlas to ensure you won't drive by a museum of math, science, or technology in the world, without a quick stop.

From the Escher Museum in The Hague, home of M.C. Escher’s marvelous drawings, and optical illusions to Alexander Graham Bell’s summer home is in Baddeck, Nova Scotia, Canada, where he lived from 1889 to 1922, you can now navigate your way through The Geek Atlas with a iPhone app.

Yep, Alexander Graham Bell might just roll over in his grave when your arrive with your Geek Atlas Companion app on your iPhone.

European destinations are well represented in the book, so if you're in England, stop at Oxford's Museum of History and Science with over 15,000 items collected since antiquity. Thankfully, no one there ever erased the blackboard displaying Einstein’s 1931 calculation showing the age of the universe based on its expansion.
