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

Get down little puppeh! My whippet does that, but only when trying to get her “bitch pants” off

According to BuzzFeed, my university is quite sexy … but not particularly academic. (It’s in the lower right quadrant.) This explains a surprisingly large amount of my students’ in-class performance. I am singularly incapable of judging their out-of-class performance, and strongly desire to keep it that way.
I say “fuck that study” :P

tumblr has taught me more about real life than real life ever has
did i just learn a second language
I’ve been waiting for this for ages.
WHY THE F CK CANT THEY JUST WRITE THIS SHIT
Probably because this allows communication without the need to use a particular language.

Today we look at a photograph of Edwin Hubble made in 1937 — arguably the single greatest photo ever made of a scientist at work.

I find it really cool that I am sitting right now about 150 ft away from where this was taken :)

Tall dogs: Breeds that aren't my favorite but I would own:
I love Borzoi, and will be getting one in 2014, BUT, I was also thinking there are a lot of other breeds that I love, and if one came my way I wouldn’t hesitate taking. These are them:
-Old English Sheepdog
-Belgian Malinois
-Beauceron
-Shih Tzu (I HAVE ONE NOW <3)
-Border Collie
-Collie…
Do you have a breeder in mind for your incoming Zoi? If not, my fiancee and I know many of them from Canada, the US, NZ, and the EU, let us know and we can put you in touch with them :)
It is obvious that the two offenders saw the victim as someone that could be treated as a thing. This is not about sex, it is about power and control. I guess that is what I am getting at. Sex was probably not the hardest thing for the two to get, so that wasn’t the objective. When you hear the jokes being made during the crime, it is the purest contempt.
So, how do you fix that? I’m just shooting rubber bands at the night sky but here are a few ideas: Put women’s studies in high school the curriculum from war heroes to politicians, writers, speakers, activists, revolutionaries and let young people understand that women have been kicking ass in high threat conditions for ages and they are worthy of respect.
Total sex ed in school. Learn how it all works. Learn what the definition of statutory rape is and that it is rape, that date rape is rape, that rape is rape.
In the spirit of equal time, sites like Huffington Post should have sections for male anatomy hanging out instead of just the idiotic celebrity “side boob” and “nip slip” camera ops. I have no idea what that would be like to have a camera in my face at every turn, looking for “the” shot. I know what some of you are saying. “Then why do they wear clothes like that unless they want those photos taken?” I don’t know what to tell ya. Perhaps just don’t take the fuckin picture? Evolve? I don’t know.
Education, truth, respect, equality—these are the things that can get you from a to b very efficiently.
