E = mc2. It’s hands-down the most well known equaÂtion out there. But how many have the faintest idea what the equaÂtion realÂly means? Not too long ago, PBS’ NOVA put togethÂer a “docuÂdÂraÂma,” called EinÂstein’s Big Idea, which took a close look at how EinÂstein arrived at the equaÂtion and what it means. Along with the proÂgram, NOVA proÂduced some relatÂed media resources, among which you’ll find a series of podÂcasts (iTunes — Feed — mp3) feaÂturÂing 10 top physiÂcists (includÂing two Nobel Prize winÂners) who briefly explain the meanÂing and imporÂtance of E = mc2. In addiÂtion, and perÂhaps even betÂter, they’ve postÂed an audio clip of EinÂstein himÂself explainÂing what the equaÂtion is all about. You’ll find many good resources here, so have a good look around.
If physics intrigues you, you should also check out a new StanÂford course that’s being disÂtribÂuted for free via video podÂcast. The course, ModÂern TheÂoÂretÂiÂcal Physics: QuanÂtum EntanÂgleÂment, is preÂsentÂed by Leonard Susskind, whom many conÂsidÂer the father of string theÂoÂry, a conÂtroÂverÂsial innoÂvaÂtion in physics that squares quanÂtum theÂoÂry with relÂaÂtivÂiÂty and explains the nature of all matÂter and forces. Now, when Susskind disÂcussÂes quanÂtum entanÂgleÂment, he is sureÂly getÂting into some heady, cutÂting-edge stuff. But the good thing is that the very popÂuÂlar course was preÂsentÂed through StanÂford’s ConÂtinÂuÂing StudÂies ProÂgram (where I work, just to put my cards on the table), and was geared toward the genÂerÂal pubÂlic. The course is expectÂed to last a full year, and it should result in 30 free two-hour lecÂtures, which will all be gradÂuÂalÂly postÂed online. You can find a more detailed course descripÂtion here.
