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.<span id="more-108307"></span></p> <p>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.</p> <p>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:</p> <p>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.</p> <p>In case you’re wondering why the famous equation says Δ</p> </blockquote>http://gelliebeans20.tumblr.com/post/51130943285http://gelliebeans20.tumblr.com/post/51130943285Thu, 23 May 2013 01:32:32 -0400<img src="http://24.media.tumblr.com/50bda4c2a8becf46cbff2b5d163d3365/tumblr_mn6gd8iEHr1qgwqw9o1_500.gif"/><br/><br/>http://gelliebeans20.tumblr.com/post/51130580052http://gelliebeans20.tumblr.com/post/51130580052Thu, 23 May 2013 01:24:53 -0400<img src="http://25.media.tumblr.com/tumblr_m4gg3nTKyb1qee7ixo1_r1_250.gif"/><br/> <br/><img src="http://25.media.tumblr.com/tumblr_m4gg3nTKyb1qee7ixo2_250.gif"/><br/> <br/>http://gelliebeans20.tumblr.com/post/51130562595http://gelliebeans20.tumblr.com/post/51130562595Thu, 23 May 2013 01:24:32 -0400<img src="http://24.media.tumblr.com/ab2325c9934973a40bf129c8e2579e99/tumblr_mn4c6eODfx1r7ksqyo1_500.gif"/><br/><br/><blockquote> <div> <p><a href="http://notoriousgifs.tumblr.com/" target="_blank">Click for the most hilarious, relatable gifs.</a></p> </div> </blockquote> <p>me too</p>http://gelliebeans20.tumblr.com/post/51130482011http://gelliebeans20.tumblr.com/post/51130482011Thu, 23 May 2013 01:22:50 -0400<img src="http://25.media.tumblr.com/1f2c2795e9077df5b43b63036600b027/tumblr_mn6j0nFXyY1qgwqw9o1_500.jpg"/><br/><br/><p>indeed</p>http://gelliebeans20.tumblr.com/post/51130452354http://gelliebeans20.tumblr.com/post/51130452354Thu, 23 May 2013 01:22:13 -0400<img src="http://25.media.tumblr.com/4206e22f39c7adfbfe3db2465259abf5/tumblr_mn6jegmh5C1qgqj2zo1_500.jpg"/><br/><br/>http://gelliebeans20.tumblr.com/post/51130413583http://gelliebeans20.tumblr.com/post/51130413583Thu, 23 May 2013 01:21:25 -0400<img src="http://25.media.tumblr.com/6e29de5560f4084b9da3eb867e697fc5/tumblr_mgjh9jAACS1qfu0iao1_500.jpg"/><br/><br/>http://gelliebeans20.tumblr.com/post/51130112567http://gelliebeans20.tumblr.com/post/51130112567Thu, 23 May 2013 01:15:12 -0400<img src="http://25.media.tumblr.com/8d25b49e1b02ee56c9e9658227d66fec/tumblr_mn4d62ggx11qjjy0lo1_500.jpg"/><br/> <br/><img src="http://25.media.tumblr.com/4665c5e779d318a04c9710ea1bf7ebac/tumblr_mn4d62ggx11qjjy0lo2_500.jpg"/><br/> <br/><img src="http://25.media.tumblr.com/6a175a43f7da68f009066c7bd180f308/tumblr_mn4d62ggx11qjjy0lo3_500.jpg"/><br/> <br/><p><a class="tumblr_blog" href="http://ak47mx.tumblr.com/post/51001452700/pick-up-a-cornetto-by-andrew-kolb" target="_blank">ak47mx</a>:</p> <blockquote> <p><em><strong>Pick up a Cornetto…</strong></em> by <a href="http://www.flickr.com/photos/kolbisneat/" title="Andrew Kolb" target="_blank">Andrew Kolb.</a></p> </blockquote>http://gelliebeans20.tumblr.com/post/51127171611http://gelliebeans20.tumblr.com/post/51127171611Thu, 23 May 2013 00:22:07 -0400<img src="http://24.media.tumblr.com/13e37b67b60307f079e354d065d1875e/tumblr_mlt5vj1p1H1rgk4n0o8_250.gif"/><br/> <br/><img src="http://25.media.tumblr.com/9930a58ad1f9f15971a3b5da341f3961/tumblr_mlt5vj1p1H1rgk4n0o1_250.gif"/><br/> <br/><img src="http://24.media.tumblr.com/991ef3dabe3acdfa9d2fb8d95749d75a/tumblr_mlt5vj1p1H1rgk4n0o3_250.gif"/><br/> <br/><img src="http://24.media.tumblr.com/c2fe8a983867dde078978de80d453ac2/tumblr_mlt5vj1p1H1rgk4n0o2_250.gif"/><br/> <br/><img src="http://25.media.tumblr.com/2e50f9fa499da8bd88b17ffcceef09e3/tumblr_mlt5vj1p1H1rgk4n0o4_250.gif"/><br/> <br/><img src="http://25.media.tumblr.com/4996dc347ecab995e38d44438f156dfd/tumblr_mlt5vj1p1H1rgk4n0o5_250.gif"/><br/> <br/><img src="http://25.media.tumblr.com/453510e1e4ea04635696ec2eba028a41/tumblr_mlt5vj1p1H1rgk4n0o7_250.gif"/><br/> <br/><img src="http://24.media.tumblr.com/f3f6ad6dc045781b39a2e99a24300ab8/tumblr_mlt5vj1p1H1rgk4n0o6_250.gif"/><br/> <br/><blockquote> <pre>Jay Park ~ Welcome MV -
