The Quantum Physics of Harry Potter, Broken Down By a Physicist and a Magician

If you con­sid­er your­self a Har­ry Pot­ter fan, you’ve almost cer­tain­ly read read all sev­en of J.K. Rowl­ing’s nov­els and watched all eight of their film adap­ta­tions. The ques­tion of where to go from there has many pos­si­ble answers. Some true believ­ers plunge straight into, and often con­tribute to, the vast body of unof­fi­cial read­ing mate­r­i­al that is Har­ry Pot­ter fan fic­tion. Oth­ers turn to the schol­ar­ship sur­round­ing Pot­ter and his world, a field that includes such stud­ies of vary­ing seri­ous­ness as The Sci­ence of Har­ry Pot­ter, Har­ry Pot­ter and Phi­los­o­phy, The Values of Har­ry Pot­ter, Look­ing for God in Har­ry Pot­ter, and If Har­ry Pot­ter Ran Gen­er­al Elec­tric. In the Uni­ver­si­ty of Toron­to lec­ture above, quan­tum physi­cist Kris­ter Shalm explains, appro­pri­ate­ly enough, the quan­tum physics of Har­ry Pot­ter.

Shalm thus faces two tasks: to explain the rel­e­vant facts of quan­tum physics in a man­ner under­stand­able to the lay­man, and the even more for­mi­da­ble chal­lenge of relat­ing the rel­e­vant facts of Har­ry pot­ter in a way that won’t com­plete­ly alien­ate the unini­ti­at­ed. But pulling this off in an enter­tain­ing fash­ion would seem to land right in the wheel­house of a man who bills him­self as “The Danc­ing Physi­cist” and states his mis­sion to “make some of the mind-bog­gling con­cepts in quan­tum mechan­ics more approach­able” by col­lab­o­rat­ing with “a magi­cian, musi­cians, and dancers.” That magi­cian, a cer­tain Dan Trom­mater, turns up in this lec­ture to com­ple­ment Shalm’s phys­i­cal angle with a mag­i­cal one. Togeth­er, they illus­trate for us how Dra­co Mal­foy’s tele­por­ta­tion tech­niques resem­ble what quan­tum physi­cists do in the lab on a reg­u­lar basis, and what rel­e­vance Schrödinger’s famous cat has to that fate­ful prophe­cy that either Har­ry Pot­ter or Lord Volde­mort would ulti­mate­ly die. (Luck­i­ly for me, Shalm does­n’t reveal which one; I haven’t read the books myself yet!)

John Lennon’s Victorian Circus Poster Lovingly Remade by Artists and Engravers

This won­drous lit­tle video is, as they say, guar­an­teed to raise a smile. Accord­ing to Bea­t­les leg­end, John Lennon was shoot­ing a pro­mo­tion­al film for “Straw­ber­ry Fields For­ev­er” in ear­ly 1967 when he passed by an antique shop and dis­cov­ered a poster from 1843 trum­pet­ing the arrival of Pablo Fan­que’s Cir­cus. The cir­cus, the poster pro­claimed, was to be “for the ben­e­fit of Mr. Kite.” Intrigued, Lennon bought the quirky Vic­to­ri­an poster, hung it on his wall at home, and then pro­ceed­ed to write “Being for the Ben­e­fit of Mr. Kite!,” the sev­enth track on Sgt. Pep­per’s Lone­ly Hearts Club Band.

Almost 45 years lat­er, Bea­t­les fans still can’t shake the poster from their minds. And, just recent­ly, Peter Dean and a team of artists decid­ed to recre­ate the poster using tra­di­tion­al meth­ods of wood engrav­ing and let­ter­press print­ing. They share their expe­ri­ence in the ele­gant video above. Your can buy your own copy of the lim­it­ed edi­tion print here.

Orson Welles Remembers his Stormy Friendship with Ernest Hemingway

In this fas­ci­nat­ing clip from a 1974 inter­view by Michael Parkin­son of the BBC, Orson Welles describes his “very strange rela­tion­ship” with Ernest Hem­ing­way, cast­ing him­self in a sto­ry of their first meet­ing as a torero opposed to Hem­ing­way’s bull.

The two men met in New York in the ear­ly sum­mer of 1937, when Welles was asked to nar­rate The Span­ish Earth, a doc­u­men­tary orga­nized by Hem­ing­way and oth­er artists to pro­mote the Rebubli­can cause dur­ing the Span­ish Civ­il War. Welles was a great admir­er of Hem­ing­way, who was 16 years his senior. When he was 18 years old he went to Spain to study bull­fight­ing after read­ing Hem­ing­way’s Death in the After­noon. But despite some sim­i­lar­i­ties, the two men were poles apart, as Welles’ anec­dote of their first meet­ing sug­gests.

The brava­do in Welles’s sto­ry may have some­thing to do with a need to com­pen­sate for his own injured pride over the recep­tion of his nar­ra­tion for The Span­ish Earth.  Under pres­sure from Lil­lian Hell­man and oth­ers in the project, who com­plained that Welles’ per­for­mance was too the­atri­cal for the doc­u­men­tary, direc­tor Joris Ivens decid­ed to scrap it and asked Hem­ing­way to come back in to read his own words. Welles lat­er drew on the inci­dent in the pro­jec­tion room as inspi­ra­tion for his script “The Sacred Beasts,” about the rela­tion­ship between a young bull­fight­er and an old­er film direc­tor. The script was even­tu­al­ly devel­oped into The Oth­er Side of the Wind, an unfin­ished film star­ring John Hus­ton as the Hem­ing­way-inspired film­mak­er Jake Han­naford. Welles was work­ing on the project when the inter­view with Parkin­son took place. You can see the com­plete inter­view on YouTube, and read a tran­script at Wellesnet.

A Short History of Romanian Computing: From 1961 to 1989

The “Politehni­ca” Uni­ver­si­ty of Timisoara, Roma­nia, an engi­neer­ing school estab­lished in 1920, takes its mot­to from Fer­di­nand I: “It’s not the walls that make a school, but the spir­it liv­ing inside.” While the walls of “Politehni­ca” are as state­ly as any­one could ask for, what’s inside, accord­ing to the short doc­u­men­tary above, is also pret­ty spiffy—the spir­it of com­put­ing his­to­ry, Roman­ian style. With a score that sounds a lit­tle like an out­take from Logan’s Run, this video gives us a tour of the university’s Muse­um of Infor­ma­tion Tech­nol­o­gy and Com­mu­ni­ca­tions, opened Novem­ber 16, 2001.

We meet a num­ber of ancient machines, many of which were respon­si­ble for design­ing build­ings and hydro­elec­tric dams and some of which still func­tion. There’s the Mecipt 1, a mas­sive 1961 main­frame sys­tem cov­ered in dials, switch­es, and rout­ing sys­tems and look­ing some­what more indus­tri­al than the machines built by Fairchild and IBM at the same time. Next comes Mecipt 2 in 1963, which was in oper­a­tion for six­teen years and did much of the build­ing design. The micro­com­put­ers TIMS and MS-100 resem­ble the orig­i­nal busi­ness machines made in the six­ties by com­pa­nies like Hewlett-Packard and Data Gen­er­al Corp. Over­all, the short doc takes us through the exper­i­men­tal course of Roman­ian com­put­ing from 1961 to 1989. The read­er who brought this to our atten­tion points out that there’s lit­tle mate­r­i­al out there on Roman­ian com­put­er engi­neer­ing. This short doc offers a rare look at a very lit­tle-known and fas­ci­nat­ing his­to­ry.

Art.sy Rolls Out Huge Archive of Fine-Art Images and an Intelligent Art Appreciation Guide

Yes­ter­day saw the launch of what you’ll sure­ly find the most intrigu­ing use of Syr­i­a’s domain name exten­sion yet, espe­cial­ly if you fol­low the visu­al arts. It serves the pun­ning site Art.sy, to which you’ll soon point your brows­er when­ev­er you want to dis­cov­er new imagery that appeals to your aes­thet­ic sen­si­bil­i­ty. Thus holds the the­o­ry, in any case, behind this ser­vice cre­at­ed by the Art Genome Project. It aims to become to visu­al art what Pan­do­ra has become to music: a vir­tu­al mind that can take your tastes, turn right back around to rec­om­mend works that please those tastes, and — in the best of all pos­si­ble out­comes, lit­tle by lit­tle — broad­en those tastes as well. Tell Art.sy what has recent­ly cap­ti­vat­ed you in the muse­ums, and it will dig through pieces from Wash­ing­ton’s Nation­al Gallery, the Los Ange­les Muse­um of Con­tem­po­rary Art, the Coop­er-Hewitt Nation­al Design Muse­um, the British Muse­um, and else­where, try­ing its best to find some­thing else that will do the same. In total, Art.sy hosts “17,000+ art­works by 3,000+ artists” from “300+ of the world’s lead­ing gal­leries, muse­ums, pri­vate col­lec­tions, foun­da­tions, and artist estates from New York to Lon­don, Paris to Shang­hai, Johan­nes­burg to São Paulo.”

Mele­na Ryzik in The New York Times describes Art.sy’s elab­o­rate sys­tem of code-based aes­thet­ic clas­si­fi­ca­tion as devel­oped by “a dozen art his­to­ri­ans who decide what those codes are and how they should be applied,” in which “some labels (Art.sy calls them “genes” …) denote fair­ly objec­tive qual­i­ties, like the his­tor­i­cal peri­od and region the work comes from and whether it is fig­u­ra­tive or abstract, or belongs in an estab­lished cat­e­go­ry like Cubism, Flem­ish por­trai­ture or pho­tog­ra­phy,” while oth­ers “are high­ly sub­jec­tive, even quirky.” Ryzik lists the pos­si­ble codes for a Picas­so as includ­ing “Cubism,” “abstract paint­ing,” “Spain,” “France” and “love,” and those for a Jack­son Pol­lock as “abstract art,” “New York School,” “splattered/dripped,” “rep­e­ti­tion” and “process-ori­ent­ed.” Here we have yet anoth­er rea­son to main­tain a high artis­tic aware­ness in our high-tech time. Still, I can’t help but recall the wise coun­sel Stephen Fry offered in an inter­view we fea­tured back in August: a tru­ly life-enrich­ing rec­om­men­da­tion engine would­n’t give you the same art you’ve always enjoyed; it would give you the exact oppo­site.

What If Money Was No Object?: Thoughts on the Art of Living from Eastern Philosopher Alan Watts

Alan Watts came to San Fran­cis­co dur­ing the ear­ly 1950s, wrote his best­seller Way of Zen, and became one of the fore­most pop­u­lar­iz­ers of Zen Bud­dhism, Hin­duism, Tao­ism and var­i­ous forms of East­ern phi­los­o­phy. His TV show, East­ern Wis­dom and Mod­ern Life (1960), intro­duced Amer­i­cans to the seem­ing­ly exot­ic con­cept of med­i­ta­tion (watch here). And his radio show and lec­tures forced lis­ten­ers to pause and look at their lives from a fresh per­spec­tive. Again and again, Watts chal­lenged the West­ern empha­sis on mon­ey-mak­ing to the exclu­sion of all else. We’ve heard Watts rail against this soul-crush­ing val­ue in a lec­ture ani­mat­ed by the cre­ators of South Park. (I’m not kid­ding you.) And, in the new­ly-pro­duced video above, he con­tin­ues along the same tra­jec­to­ry. So, as you drink your morn­ing cof­fee and pon­der your day, ask your­self: Are you putting mon­ey-mak­ing before hap­pi­ness itself? Or are you pur­su­ing the pas­sions that bring hap­pi­ness, achiev­ing excel­lence, and then let­ting the mon­ey fol­low? With that, I’ll let you con­tin­ue with your day.

How Political Commitment Led Lucy Lawless (AKA Xena, the Warrior Princess) to Study Philosophy

It’s cer­tain­ly not uncom­mon for celebri­ties to take up polit­i­cal caus­es, though this does not usu­al­ly lead to them get­ting arrest­ed for hol­ing up in a high tow­er oil-drilling ship for four days. What’s less com­mon is for this inter­est to bur­geon into a full-on obses­sion with all things philo­soph­i­cal, but that’s exact­ly what hap­pened to Lucy Law­less (best known as Xena, the War­rior Princess).

“I went to the UN sum­mit on sus­tain­able devel­op­ment after get­ting involved in the whole… big oil protest… and I saw all of these peo­ple work­ing very hard but seem­ing­ly at cross-pur­pos­es about how do we cre­ate a just soci­ety.” On a full two-hour episode of The Par­tial­ly Exam­ined Life Phi­los­o­phy Pod­cast (which she claims was large­ly respon­si­ble for turn­ing her on to phi­los­o­phy), she describes how this polit­i­cal inter­est drove her to look at the foun­da­tions and his­to­ries of the­o­ries of jus­tice, and even­tu­al­ly decide to go back to school to study phi­los­o­phy, which she’s now doing in New Zealand between flights to the states to film TV spots such as her recent appear­ance on NBC’s Parks and Recre­ation.

The Par­tial­ly Exam­ined Life inter­view with Law­less is a five-per­son, round­table dis­cus­sion of Tom Payne’s 2010 book, Fame: What the Clas­sics Tell Us About Our Cult of Celebri­ty. You can lis­ten here:

The the­sis of the book is that celebri­ties serve as an out­let for soci­ety’s aggres­sive instincts. Draw­ing on canon­i­cal texts about reli­gious anthro­pol­o­gy like James Fraz­er’s The Gold­en Bough, the author com­pares the treat­ment of mod­ern celebri­ties to ancient rites where young maid­ens were lav­ish­ly bestowed with finer­ies and then sac­ri­fied. Lucy thinks this well match­es her own expe­ri­ences, and talks about the exis­ten­tial weird­ness involved with being and deal­ing with the famous.

The Par­tial­ly Exam­ined Life has also cov­ered relat­ed top­ics of Freud’s Civ­i­liza­tion and its Dis­con­tents and Niet­zsche’s Geneal­o­gy of Morals. You can sub­scribe to the pod­cast on iTunes.

Marginal Revolution University Launches, Bringing Free Online Courses in Economics to the Web

A great year for open edu­ca­tion got even bet­ter with the launch of Mar­gin­al Rev­o­lu­tion Uni­ver­si­ty. Found­ed by Tyler Cowen and Alex Tabar­rok, two econ pro­fes­sors at George Mason Uni­ver­si­ty, MRUni­ver­si­ty promis­es to deliv­er free, inter­ac­tive cours­es in the eco­nom­ics space. And they’re get­ting start­ed with a course on Devel­op­ment Eco­nom­ics, a sub­dis­ci­pline that explores why some coun­tries grow rich and oth­ers remain poor. In short, issues that have real mean­ing for every­day peo­ple world­wide.

In an announce­ment on the Mar­gin­al Rev­o­lu­tion blog last month, Cowen out­lined a few of the prin­ci­ples guid­ing the project:

1. The prod­uct is free, and we offer more mate­r­i­al in less time.

2. Most of our videos are short, so you can view and lis­ten between tasks, rather than need­ing to sched­ule time for them.  The aver­age video is five min­utes, twen­ty-eight sec­onds long.  When need­ed, more videos are used to explain com­plex top­ics.

3. No talk­ing heads and no long, bor­ing lec­tures.  We have tried to recon­cep­tu­al­ize every aspect of the edu­ca­tion­al expe­ri­ence to be friend­ly to the on-line world.

4. It is low band­width and mobile-friend­ly.  No ads.

5. We offer tests and quizzes.

6. We have plans to sub­ti­tle the videos in major lan­guages.  Our reach will be glob­al, and in doing so we are build­ing upon the glob­al empha­sis of our home insti­tu­tion, George Mason Uni­ver­si­ty.

7. We invite users to sub­mit con­tent.

8. It is a flex­i­ble learn­ing mod­ule.  It is not a “MOOC” per se, although it can be used to cre­ate a MOOC, name­ly a mas­sive, open on-line course.

9. It is designed to grow rapid­ly and flex­i­bly, absorb­ing new con­tent in mod­u­lar fash­ion — note the bee­hive struc­ture to our logo.  But we are start­ing with plen­ty of mate­r­i­al.

10. We are pleased to announce that our first course will begin on Octo­ber 1.

Book­mark MRUni­ver­si­ty and look out for its cur­ricu­lum to expand. In the mean­time, you can explore more Free Online Eco­nom­ics Cours­es, a sub­set of our meta col­lec­tion, 1,700 Free Online Cours­es from Top Uni­ver­si­ties.
