The Only Known Photograph of Einstein Deriving his Famous E=mc² Equation

At a public lecture in Pittsburgh in 1934, four hundred lucky students were privy to a lecture by Albert Einstein, in which the great man mathematically derived his famous mass-energy equivalence equation: E=mc². What you see above is a photo from that lecture, and what is thought to be the only surviving photo that shows Einstein working on that derivation.

The photo was pulled from a halftone newspaper clipping by David Topper and Dwight Vincent of the University of Winnipeg, who discovered it in 2007. Sadly, everything is a bit fuzzy so you can’t really make out the famed equation itself. And even though the original article had a crisp picture of Einstein posing next to one of his blackboards, he’s next to the wrong one.

Here’s a closer look at the man and the math. If you look closely, you’ll see the mass-energy equivalence in the lower left hand corner of the blackboard on the right:

Fortunately, Topper and Vincent managed to take the blurry photo and reproduce both blackboards in their original paper. Here’s the math behind the magic, the derivation of mass-energy equivalence as presented by Albert Einstein.

In case you’re wondering why the famous equation says Δ

“Look at the sky. It’s not dark and black and without character. The black is, in fact deep blue. And over there: lighter blue and blowing through the blues and blackness the winds swirling through the air and then shining, burning, bursting through: the stars!”

Intriguing Science Art From the University of Wisconsin

“The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living.”

—Jules Henri Poincare, a French mathematician (1854-1912)

The University of Wisconsin-Madison revealed the winners of the 2012 Cool Science image contest at the beginning of the month. From clusters of cells, zebrafish neural networks to ZnO Fall Flowers as seen above, this year’s contest showed nothing but impressive content for us to enjoy.
