Explore Einstein's Brain Through His Letters

More than 10 years after its inception, the online archive of Albert Einstein's life and work relaunched this week with tons of new content — including more than 2000 high-resolution documents. Nerds, have at it!

The massive, rebooted archive is administered by the Hebrew University of Jerusalem and includes thousands of documents that were previously only available in collected volumes. Highlights, like the original handwritten manuscript in which Einstein proposes his theory of mass-energy equivalence, are available in a gallery along with personal effects. For example, Einstein wrote the postcard above recounting his observations about the solar eclipse in May 1919 to his mother. (Don't worry, the documents are translated and explained in case you don't speak German... or physics.)

History buffs will want to dig into the 80,000-record catalogue of the entire collection, which includes links to additional digitised documents. The Hebrew University plans to continue adding more images throughout the year. [Einstein Archives Online via Open Culture]
