Free: Richard Feynman’s Physics Course from Cornell (1964)

We’re beam­ing you back to 1964. Richard Feyn­man, our favorite Bon­go-play­ing, Nobel Prize-win­ning physi­cist, reduces sci­ence to the barest essen­tials, to its most fun­da­men­tal truth. If a the­o­ry does­n’t square with exper­i­ment, it’s wrong. That holds true for clever the­o­ries, ele­gant the­o­ries, and all of the rest.

This clip is just a small out­take from a sev­en-part lec­ture series that Fey­man pre­sent­ed at Cor­nell in 1964, and the lec­tures are all now freely avail­able on the web thanks to Bill Gates. You can watch the full series on our site, or on a Mis­crosoft site, but be warned: if you choose the lat­ter, you’ll need to down­load Microsoft­’s Sil­verlight soft­ware to watch the lec­tures.

Japan’s Earthquake & Tsunami: How They Happened

On March 11th, Japan suf­fered a 9.0 earth­quake, fol­lowed by a mas­sive tsuna­mi. Just weeks lat­er, NOVA has pro­duced a 47 minute doc­u­men­tary that does an impres­sive job of explain­ing the sci­ence behind these twin geo­log­ic cat­a­stro­phes. The pro­gram fol­lows Roger Bil­ham, a seis­mol­o­gist at the Uni­ver­si­ty of Col­orado, who arrived in Japan two days after the quake. And what you get is a blow-by-blow account of the unfold­ing events, cou­pled with some sound analy­sis and stun­ning footage (like the ground split­ting open and push­ing water to the sur­face.) This is by far the most sub­stan­tive treat­ment of Japan’s quake/tsunami that we’ve encoun­tered to date…

The Billion-Bug Highway You Can’t See

When you look up in the sky, what do you see besides the blue sky, clouds, the occa­sion­al bird and plane, the Sun, and the Moon? In this whim­si­cal ani­mat­ed video from NPR, we learn about the var­i­ous insects – the wasps, aphids, bee­tles, etc. – that inhab­it the upper lev­els of the tro­pos­phere. What’s incred­i­ble is that in the peak sum­mer months, there are bil­lions of these insects high in the sky, with some cruis­ing at an alti­tude of 19,000 feet, equiv­a­lent to the height of Mount McKin­ley!

For the botanists out there: the title of the video is a lit­tle mis­lead­ing, as the word bug actu­al­ly refers to an insect of the order Hemiptera; to be pre­cise, we have to call it the bil­lion-insect high­way…

Scifoo: How Would You Spend a Billion Dollars?

Sci­foo is an annu­al “uncon­fer­ence” c0-host­ed in Moun­tain View, Cal­i­for­nia by Google, O’Reil­ly Media and Nature pub­lish­ing. It’s par­tic­i­pant-dri­ven, cross-pol­li­nat­ing, and high­ly unstruc­tured, rely­ing more on brain­storms and erasable white boards than Pow­er­Point pre­sen­ta­tions and lec­ture halls. Accord­ing to Nature’s page for Sci­foo 2011:

200 lead­ing sci­en­tists, tech­nol­o­gists, writ­ers and oth­er thought-lead­ers will gath­er once more at the Google­plex for a week­end of unbri­dled dis­cus­sion, demon­stra­tion and debate.

The event is invi­ta­tion-only, but if your own posi­tion as glob­al thought-leader has not yet been rec­og­nized, you can take com­fort in these engag­ing short videos from past Sci­foo con­fer­ences. In addi­tion to film­ing the oblig­a­tory gen­er­al overview, Nature also asked some of the atten­dees – includ­ing a cli­mate sci­en­tist, an astro­bi­ol­o­gist, and a Nobel lau­re­ate in physics – for short answers on spe­cif­ic top­ics, like fears for the futurepre­dic­tions for the next decade and our per­son­al favorite ques­tion: “If you had $1 bil­lion to spend on just one project, what would it be?”

Some­thing that should inspire teach­ers: A good chunk of these experts’ dream projects involved push­es for wide­spread edu­ca­tion reform and dis­sem­i­na­tion of exist­ing knowl­edge, rather than financ­ing for advances in their par­tic­u­lar spe­cial­ties. We par­tic­u­lar­ly liked skep­tic Michael Sher­mer’s vision of world­wide crit­i­cal think­ing pro­grams that would teach stu­dents “not what to think, but how to think.” (2:34)

Biology That Makes Us Tick: Free Stanford Course by Robert Sapolsky

First thing you need to know: Before doing any­thing else, you should sim­ply click “play” and start watch­ing the video above. It does­n’t take long for Robert Sapol­sky, one of Stan­ford’s finest teach­ers, to pull you right into his course. Bet­ter to watch him than lis­ten to me.

Sec­ond thing to know: Sapol­sky is a MacArthur Fel­low, a world renowned neu­ro­bi­ol­o­gist, and an adept sci­ence writer best known for his book, Why Zebras Don’t Get Ulcers. Much of his research focus­es on the inter­play between the mind and body (how biol­o­gy affects the mind, and the mind, the body), and that rela­tion­ship lies at the heart of this course called “Human Behav­ioral Biol­o­gy.”

Now the third: Human Behav­ioral Biol­o­gy is avail­able on YouTube and iTunes for free. The course, con­sist­ing of 25 videos span­ning 36 hours (watch them all below), is oth­er­wise list­ed in the Biol­o­gy sec­tion of our big list of Free Online cours­es (now 1,700 cours­es in total).

Lawrence Krauss: Every Atom in Your Body Comes From a Star

Lawrence Maxwell Krauss, author of the best-sell­ing book The Physics of Star Trek, is a the­o­ret­i­cal physi­cist and Pro­fes­sor of Physics at Ari­zona State Uni­ver­si­ty. His research focus­es on the begin­ning and the end of the uni­verse.

This past Jan­u­ary, Krauss attend­ed the World Eco­nom­ic Forum in Davos and was asked by 99 Faces TV to talk about his work. In a rel­a­tive­ly short 381 sec­onds, he speaks about the scale of the uni­verse, the con­cept of dark ener­gy and explains how “you real­ly are star­dust.” That is to say, every lit­tle atom in your body comes from a super­no­va (or explod­ing star). Krauss elab­o­rates on this poet­ic thought in this 2009 video (def­i­nite­ly rec­om­mend­ed), and he’ll have more to say in his new book, A Uni­verse from Noth­ing.

A is for Atom: Vintage PR Film for Nuclear Energy

As a dev­as­tat­ed Japan con­tin­ues to strug­gle with the dam­age to its nuclear facil­i­ties, sev­er­al oth­er nations have begun recon­sid­er­ing their nuclear poli­cies. Ger­many, for exam­ple, has tem­porar­i­ly closed down sev­en aging nuclear reac­tors, and oth­er coun­tries (includ­ing Rus­sia, Chi­na, and the US) have announced checks of their own safe­ty stan­dards.

Cyn­ics might sug­gest that these announce­ments are cal­cu­lat­ed less to make sub­stan­tive changes than to calm a fright­ened pub­lic, and attempts to man­age per­cep­tions of the atom­’s volatile pow­ers are noth­ing new. They began imme­di­ate­ly after the bomb­ings of Hiroshi­ma and Nagasa­ki. The video above, pro­duced by Gen­er­al Elec­tric in 1952, was one of many Atom­ic Ener­gy “PR films” designed to sway pub­lic opin­ion in favor of this prof­itable and pow­er­ful new ener­gy resource. (Coin­ci­den­tal­ly, GE built the Fukushi­ma reac­tor that’s now in deep trou­ble.)

A is for Atom was a huge hit — it won sev­er­al hon­ors, includ­ing a spe­cial prize at the Venice Film Fes­ti­val and a Mer­it Award from Scholas­tic Teacher. In some ways those hon­ors were deserved. The movie is a spright­ly car­toon with cheer­ful nar­ra­tion and expla­na­tions of some dif­fi­cult physics, even as it avoids any engage­ment with the dark sides of nuclear ener­gy. In fact, the whole mes­sage boils down to a reas­sur­ance that the atom­’s mas­sive poten­tial is all “with­in man’s com­mand.”

Floor of Kilauea Volcano Crater Collapses Before Your Eyes

Nature shows its force once again, this time in Hawaii. Last week­end, the U.S. Geo­log­i­cal Sur­vey detect­ed unusu­al activ­i­ty at the Kilauea vol­cano. And, with­in min­utes, the floor of the Pu’u O’o crater began to col­lapse. It’s all cap­tured in the short video above. The Wash­ing­ton Post has a lit­tle more on the sto­ry…
