point to my life, and yell
“None of this was part of my Goddamn plan!”
But I know he’d just shrug and say, “I’m sorry.
I never meant to give the impression that this
would be easy. I know none of this
But that’s why I invented time. It’s a slow,
steady promise. If you just hold on,
just white knuckle grip keep breathing,
time will take you far enough away
from anything. It’s a blessing.
It will heal you if you let it.

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
wow, known the facts behind this takes my breath away. epic nerdry at work for me right now.
