Neil deGrasse Tyson Delivers the Greatest Science Sermon Ever

Just when you think you’ve had enough Neil deGrasse Tyson, anoth­er not-to-miss video comes along. This one comes from the 2006 Beyond Belief Con­fer­ence, and it fea­tures the astro­physi­cist giv­ing what’s been called the “great­est sci­ence ser­mon ever.” As a young­ster, Tyson stepped into the Hay­den Plan­e­tar­i­um (the insti­tu­tion he now runs) and he felt an unshak­able call­ing to study the uni­verse. It was­n’t unlike the feel­ing some­one under­goes when they’re reli­gious­ly born again. And ever since, Tyson has expe­ri­enced rev­e­la­tion after rev­e­la­tion, epiphany after epiphany, when study­ing the uni­verse, and espe­cial­ly when­ev­er he’s remind­ed that, chem­i­cal­ly speak­ing, we are in the uni­verse, and the uni­verse is in us. We’re all made of the same star­dust. How can that not leave us with an incred­i­bly spir­i­tu­al feel­ing?

Breaking News: Socrates Tried Again in Athens and Acquitted!



Note: the action starts at about the two minute mark, and the video is accom­pa­nied by an Eng­lish trans­la­tion.

The tri­al and exe­cu­tion of Socrates at Athens in 399 B.C.E. has come down to us as the arche­type of intel­lec­tu­al mar­tyr­dom. But the facts of the case, as fil­tered through the writ­ings of Socrates’ stu­dents Xenophon and Pla­to, are sketchy.  “Why,” asks Dou­glas Lin­der on the Famous Tri­als Web site, “in a soci­ety enjoy­ing more free­dom and democ­ra­cy than any the world had ever seen, would a sev­en­ty-year-old philoso­pher be put to death for what he was teach­ing?”

Last Fri­day the Onas­sis Cul­tur­al Cen­tre in Athens gave Socrates a new tri­al, assem­bling a pan­el of dis­tin­guished jurists from Europe and Amer­i­ca to reopen the case. As the Onas­sis Cen­tre’s Web site explains, the event was “not a re-enact­ment but a mod­ern per­spec­tive based on cur­rent legal frame­work sup­ple­ment­ed with ancient Greek ele­ments and com­i­cal the­atrics.” This time the ver­dict was different–but just bare­ly. The vote by the jury was a 5–5 tie, which meant Socrates was acquit­ted. The audi­ence’s vote was more deci­sive: 5 to con­vict, 584 to acquit. Of course, it was a lit­tle late for Socrates.

The Ideas of Noam Chomsky: An Introduction to His Theories on Language & Knowledge (1977)

We’ve fea­tured the lin­guist and polemi­cist Noam Chom­sky here before, and not two weeks ago we post­ed about philoso­pher-broad­cast­er Bryan Magee. The Ideas of Noam Chom­sky brings the two men togeth­er for a chat about lin­guis­tics, the phi­los­o­phy of lan­guage, human cog­ni­tive pro­gram­ming, and the phi­los­o­phy of sci­ence. Though Magee intro­duces Chom­sky, a high­ly non­tra­di­tion­al intel­lec­tu­al to his adher­ents and detrac­tors alike, as “some­thing of a jok­er in the pack, as far as phi­los­o­phy is con­cerned,” he inter­views him with all the atten­tive­ness and respect he brings to dis­cus­sions with pure­ly philo­soph­i­cal lumi­nar­ies. Clear­ly, Magee wants to know more about Chom­sky’s the­o­ries of lan­guage, and espe­cial­ly about their impli­ca­tions for what he calls the dom­i­nant philo­soph­i­cal prob­lem: “that of the rela­tion­ship between lan­guage and the world.”

Rarely ques­tioned along these lines in the media, Chom­sky responds thought­ful­ly and in detail. This ulti­mate­ly leads to a con­ver­sa­tion about the divide between where mean­ing­ful sci­en­tif­ic the­o­ries can devel­op, and where our cog­ni­tive lim­i­ta­tions might pre­vent them from devel­op­ing. You’ll notice that none of this has to do with pol­i­tics, and polit­i­cal guid­ance is what most of Chom­sky’s fans have expect­ed from him over the decades. While even Chom­sky him­self has admit­ted to see­ing no con­nec­tion between his aca­d­e­m­ic and activist careers, Magee pur­sues a line of inquiry late in the broad­cast meant to tie them togeth­er. Magee asks astute ques­tions and Chom­sky pro­vides hon­est answers, but find­ing a com­mon root between ideas like deep gram­mar and anar­chist social­ism per­haps remains an intel­lec­tu­al stunt best not tried at home.

The Open Goldberg Variations: J.S. Bach’s Masterpiece Free to Download

First pub­lished in 1741, J.S. Bach’s Gold­berg Vari­a­tions is often con­sid­ered the most ambi­tious com­po­si­tion ever writ­ten for harp­si­chord. As this con­ver­sa­tion at NPR notes, the piece begins “with an ini­tial melody, the Aria, fol­lowed by 30 short but bril­liant vari­a­tions built on eight notes that Bach appears to have bor­rowed from Han­del.” It’s an impres­sive exam­ple of musi­cal one-upman­ship — so impres­sive that the demand­ing piece still cap­tures our often divid­ed atten­tion today.

Now, with no fur­ther delay, let me direct your atten­tion to The Open Gold­berg Vari­a­tions, the first Kick­starter-fund­ed, open source record­ing of Bach’s mas­ter­piece, avail­able entire­ly for free. If you click here, you can down­load and share the new­ly-released record­ing by Kimiko Ishiza­ka, per­formed on a Bösendor­fer 290 Impe­r­i­al piano in Berlin. You can do pret­ty much what­ev­er you want with the record­ing because it’s released under a Cre­ative Com­mons Zero license, which auto­mat­i­cal­ly puts things in the pub­lic domain.

You can also stream the Open Gold­berg Vari­a­tions below, and don’t miss this very relat­ed item: How to Down­load the Com­plete Organ Works of J.S. Bach for Free. And then this bonus: Glenn Gould’s Per­for­mance of the Gold­berg Vari­a­tion’s online.

Measuring the Universe: How Astronomers Learned to Measure Celestial Distances Explained with Animation

Have you ever won­dered how astronomers fig­ure out the mind-bog­gling dis­tances between the Earth and var­i­ous astro­nom­i­cal objects? In this infor­ma­tive ani­mat­ed video from the Roy­al Obser­va­to­ry at Green­wich, we learn the fun­da­men­tals of the Cos­mic Dis­tance Lad­der, the suc­ces­sion of meth­ods used to deter­mine those dis­tances.

The video was made for “Mea­sur­ing the Uni­verse: from the tran­sit of Venus to the edge of the cos­mos,” an exhib­it that will be on dis­play at the obser­va­to­ry through Sep­tem­ber 2. The exhib­it is timed to coin­cide with this year’s rare tran­sit of Venus, which will be vis­i­ble from Earth on June 5 and 6 and won’t hap­pen again until 2117. The tran­sit of Venus played a key role in the his­to­ry of astrom­e­try. In 1663 the Scot­tish math­e­mati­cian and astronomer James Gre­go­ry pro­posed a method of tim­ing the move­ment of Venus across the Sun from two wide­ly sep­a­rat­ed points on the Earth and using the dif­fer­en­tial to cal­cu­late the sun’s mean equa­to­r­i­al par­al­lax and, by tri­an­gu­la­tion, the Sun’s dis­tance from the Earth.

Know­ing the dis­tance from the Earth to the Sun, we can then fig­ure out the dis­tances of some stars using the same method of trigono­met­ric par­al­lax. But as astronomer Olivia John­son explains in the video, that tech­nique can only be used to mea­sure the clos­est stars. For dis­tances greater than 500 light years, oth­er meth­ods are required. When the objects in ques­tion have a known luminosity–in oth­er words, when they are “stan­dard can­dles”–the inverse square law of light can be used to cal­cu­late dis­tances. Those mea­sure­ments, along with Hub­ble’s Law and the Doppler Effect, enable even fur­ther cal­cu­la­tions extend­ing to the edge of the known cos­mos.

“What’s most incred­i­ble to me,” says John­son, “is how all these mea­sure­ments build on each oth­er. It’s only by know­ing the scale of our Solar System–the dis­tance between the Earth and Sun–that we’re able to mea­sure dis­tances to near­by stars using par­al­lax. If we can learn how far it is to some near­by stan­dard can­dles using par­al­lax, we can then use com­par­isons between stan­dard can­dles to mea­sure the dis­tances to far­ther stars and galax­ies. Final­ly, by study­ing the motions of galax­ies with stan­dard can­dles, we learn we can use red­shift to mea­sure dis­tances through­out our expand­ing Uni­verse.”

The Hig­gs Boson, AKA the God Par­ti­cle, Explained with Ani­ma­tion

Daniel Dennett (a la Jeff Foxworthy) Does the Routine, “You Might be an Atheist If…”

The Amer­i­can come­di­an Jeff Fox­wor­thy has a well known com­e­dy rou­tine called “You Might be a Red­neck If,” where he lists the self-mock­ing pos­si­bil­i­ties that answer the ques­tion. For exam­ple: You Might be a Red­neck If …

  1. Your wife has ever said, “Come move this trans­mis­sion so I can take a bath.”
  2. You own a home­made fur coat.
  3. You think a sub­di­vi­sion is part of a math prob­lem.
  4. You’ve ever financed a tat­too.
  5. You have ever used lard in bed.

The philoso­pher and cog­ni­tive sci­en­tist Daniel Den­nett picked up on this schtick when speak­ing at the Glob­al Athe­ist Con­ven­tion in Mel­bourne, Aus­tralia. And he asked a series of ques­tions meant to show that peo­ple might be a lit­tle less reli­gious, or a bit more athe­ist, than they might care to admit. So here it goes: You Might be an Athe­ist If…

  1. You don’t believe that Jesus is lit­er­al­ly the son of God.
  2. You don’t believe God actu­al­ly lis­tens to each and every­one’s prayers.
  3. You don’t think God picks sides when coun­tries go to war (or when foot­ball teams play each oth­er).
  4. Or, to put things dif­fer­ent­ly, If you believe God isn’t a per­son­al God, but rather is a benign force, a con­cept that enrich­es peo­ple’s lives.

You get the gist. By the time you’re done with the 45 minute talk, you’ll know whether you’re indeed a the­ist, or per­haps an athe­ist after all. It’s a real­i­ty check either way.

Vladimir Nabokov–Channelled by Christopher Plummer (RIP)–Teaches Kafka at Cornell

“From my point of view,” writes Vladimir Nabokov in Lec­tures on Lit­er­a­ture, “any out­stand­ing work of art is a fan­ta­sy inso­far as it reflects the unique world of a unique indi­vid­ual.” He also says it in the video above, a lec­ture on Franz Kafka’s The Meta­mor­pho­sis orig­i­nal­ly aired by WQED in Pitts­burgh. (Find Kafka’s clas­sic work in our col­lec­tion of Free eBooks and Free Audio Books.) But he does­n’t say it him­self; he says it through Christo­pher Plum­mer, who por­trays Nabokov teach­ing in a 1989 re-cre­ation of late-1940s Cor­nell Uni­ver­si­ty. Lit­er­ar­i­ly inclined stu­dents of the era (includ­ing Unit­ed States Supreme Court Jus­tice Ruth Bad­er Gins­burg) must have expe­ri­enced a sim­i­lar intro­duc­tion to Kaf­ka in Nabokov’s class­es, per­haps down to his sketch of poor Gre­gor Sam­sa’s bee­tle form. But this pro­duc­tion adds the the­atri­cal touch, sure­ly not a fea­ture of Cor­nel­l’s lec­ture halls in those days, of spot­light­ing Plum­mer-as-Nabokov and dark­en­ing every­thing else when­ev­er he reads from the sto­ry.

Plum­mer him­self says a few words about Nabokov at the begin­ning of the video, and he assumes the Russ­ian nov­el­ist’s per­sona at about 1:38. Does Plum­mer nail Nabokov’s dis­tinc­tive­ly multi­na­tion­al accent? Does Nabokov’s obser­va­tion that Gre­gor Sam­sa nev­er uses his wings mean any­thing of impor­tance?

Will we ever enter anoth­er era when pub­lic tele­vi­sion res­ur­rects cul­tur­al lumi­nar­ies to give lec­tures by way of our time’s most respect­ed thes­pi­ans? This half-hour pro­gram gives us many such ques­tions to pon­der, and even if we can’t answer them, those of us who failed to draw inspi­ra­tion from the Robin Williams of Dead Poets Soci­ety will sure­ly find, in Plum­mer’s majes­tic eccen­tric­i­ty, a briefer but more mem­o­rable teacher­ly per­for­mance.

Andy Samberg Announces Death of Liberal Arts, Coolness of Science Majors at Harvard Class Day

Every time Har­vard Class Day rolls around, you can expect a few good laughs from a come­di­an. In years past, Sacha Baron Cohen (a Cam­bridge grad), appear­ing as Ali G, offered some words of non­sen­si­cal wis­dom to Har­vard grads. Amy Poehler and Will Fer­rell have done the same. This year brings Andy Sam­berg, a Sat­ur­day Night Live cast mem­ber and co-star in var­i­ous com­ic films. The high­lights?

  • 4:29 mark: Announces that His­to­ry, Lit­er­a­ture, any­thing relat­ed to Art, and any­thing that ends with “Stud­ies,” are offi­cial­ly use­less.
  • 5:12 mark: Declares that Math and Sci­ence majors are cool .… final­ly.
  • 9:13 mark: Reads poem by WB Yeats in his own, nov­el way.
  • 10:20 mark: Impres­sions begin.
  • 14:07: Awk­ward­ly comes on to all the moth­ers in the crowd.
  • 15:04: Awk­ward­ly comes on to all the fathers in the crowd.
