This digitized image taken from a screen shot of a new iPad app, provided Sept. 24, 2012 by the National Museum of Health and Medicine Chicago, shows an image of a portion of the brainstem of renowned theoretical physicist Albert Einstein. The new application to be released Tuesday, Sept. 25 will allow users to see Einstein's brain as if they were looking through a microscope. The application promises to make detailed images of his brain more accessible to scientists than ever before. Teachers, students and anyone who's curious also can get a look.
