Did you ever wonder what was on Albert Einstein’s mind? Curious visitors arriving on flights to Philadelphia can now find out.

The Mütter Museum, a one-of-a-kind medical museum located in Center City Philadelphia is currently displaying samples of the German physicist’s brain.

According to a report in the Washington Post, an 82-year-old neuropathologist recently donated 46 slides containing Einstein’s gray matter to the museum.

This isn’t the first “out there” exhibit at the museum. Mütter regularly displays collections of medical oddities and is best known for its large Hyrtl Skull Collection.
