Teaching on YouTube Goes Viral

Last week, Alexan­dra Juhasz con­tributed a guest piece review­ing her exper­i­men­tal efforts to make YouTube an effec­tive teach­ing tool. And it did­n’t take long for the web to take notice. Soon after we post­ed her review, The Wired Cam­pus (Chron­i­cle of High­er Edu­ca­tion) took an angle on the piece. Next, the ven­er­a­ble Ars Tech­ni­ca used the post as a spring­board for its own sum­ma­ry. And final­ly, that sto­ry soon reached the home­page of Digg.com, which inevitably meant that Alexan­dra’s piece got picked up by umpteen small­er blogs. It’s always fun to watch the rip­ple effects of the web go through their motions.

Self-Regenerating Robots

The Uni­ver­si­ty of Penn­syl­va­nia has done it. They’ve cre­at­ed a robot that you can kick apart, and it knows how to reassem­ble itself. Eerie stuff. Give it a few decades, and these guys (the robots and the stu­dents) will be run­ning the show. (Video added to our YouTube playlist)

The British Slant on the Mac v. PC Ads

Across the pond, Apple is run­ning a series of ads fash­ioned after the “Mac v. PC” com­mer­cials that have run so suc­cess­ful­ly in the States. Although the vocab­u­lary and accent are nat­u­ral­ly dif­fer­ent, the gist of the British ads is essen­tial­ly the same. Yes, Apple’s schtick trans­lates well, and I’m declar­ing the third one my favorite. (See the series of com­mer­cials below.)

As our read­ers from Lon­don will know (fact: we have more read­ers from Lon­don than any oth­er one city), the actors in Apple’s ads are hard­ly unfa­mil­iar. The two — David Mitchell (PC) and Robert Webb (Mac) — star in the award-win­ning Eng­lish sit­com, Peep Show, which is just about to begin a new sea­son. (Watch sec­ond clip below. Note that it fea­tures adult lan­guage and themes.)

Body of War: Paralyzed in Iraq and the Long Road Back

On the Amer­i­can home front, the Iraq war has entered its apa­thet­ic phase. The war con­tin­ues to grind on, but the mis­sion gets far less news ink than before, and the debate over the war’s mer­its and tac­tics rarely gets hashed back through. That’s per­haps because many have decid­ed to men­tal­ly park the issue until a new admin­is­tra­tion takes over next year. Or because declin­ing home prices and ris­ing food and gas costs have elbowed the Iraq issue aside. Unde­terred, Phil Don­ahue and Ellen Spiro have co-direct­ed a new doc­u­men­tary called Body of War. Being released in US the­aters this month, the doc­u­men­tary (fea­tur­ing music arranged by Eddie Ved­der) tracks the dai­ly life of Tomas Young, a sol­dier shot and par­a­lyzed dur­ing his first week of fight­ing in Iraq, and it gives you a rare glimpse into the dif­fi­cult road that Young and oth­ers have had to trav­el. All of this makes tan­gi­ble some­thing that the cor­po­ra­tized media has­n’t cov­ered much — the real human costs of this war. To date, 4,361 Amer­i­can sol­diers have died in Iraq; over 30,000 have been injured in hos­tile action; and sui­cides of return­ing vets have report­ed­ly risen to alarm­ing rates. Below, we have post­ed the trail­er for the film. In addi­tion, I’d point you to this recent pod­cast by Bill Moy­ers (iTunes — Feed — Web Site), which intro­duces you to Tomas Young, Phil Dono­hue, Ellen Spiro and the film they made.

Thomas Friedman (While Not Dodging Eco-Pies) Argues “Green is the New Red, White & Blue”

Speak­ing at Brown Uni­ver­si­ty ear­li­er this week, Thomas Fried­man had to deal with some unfor­tu­nate extra-cur­ric­u­lar activ­i­ties. As he took the stage, two stu­dents call­ing them­selves the “Green­wash Gueril­las” launched pies (video here) at Fried­man and large­ly missed. But they did leave behind some pam­phlets spelling out their motives. Accord­ing to The Brown Dai­ly Her­ald, the Pulitzer Prize-win­ning jour­nal­ist for The New York Times deserved this dis­rup­tion because of “his sick­en­ing­ly cheery applaud for free mar­ket cap­i­tal­is­m’s con­quest of the plan­et” and “for help­ing turn envi­ron­men­tal­ism into a fake plas­tic con­sumer prod­uct for the priv­i­leged.” Some­where the giants of rev­o­lu­tion­ary rhetoric are gri­mac­ing and won­der­ing what hap­pened to their once well prac­ticed art.

Now that I’ve got your atten­tion, I want to point you to a talk that Fried­man gave last year at Stan­ford — Green is the New Red, White and Blue (iTunes). The talk takes you into the heart of Fried­man’s com­plex think­ing about the envi­ron­ment (and all that the Green Gueril­las odd­ly take issue with). And it’s pre­sent­ed with the same intel­li­gence that you’ll find on dis­play in the sec­ond most down­loaded pod­cast on iTunes U: The World is Flat. (This sec­ond talk was pre­sent­ed at MIT, and it’s only exceed­ed in pop­u­lar­i­ty by Randy Pausch’s soul­ful lec­ture, “Real­ly Achiev­ing Your Child­hood Dreams,” which we fea­tured on Mon­day.) Fried­man’s think­ing in the Stan­ford pod­cast (give it a lis­ten, you’ll be bet­ter for it) lays the foun­da­tion for his new book due out in August — Hot, Flat, and Crowd­ed: Why We Need a Green Revolution–and How It Can Renew Amer­i­ca.
