the Khan/Nick jonas thing kinda reminds me of the time i read Spock/Snape
except the former def sounds worse
their rock pose
omg
they look like the wiggles
Since apparently im on an Ellie Goulding kick. By far my favorite song from her.
Photogravures of Ottawa near the turn of the last century, including one of the original Centre Block on Parliament Hill. The Centre Block was destroyed by fire on Feb. 3, 1916 and replaced by the Peace Tower. It was named in honour of the Canadian soldiers who died in the First World War and took 11 years to construct.
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
