Google Presents an Interactive Visualization of 100,000 Stars

Stargaz­ers of all ages will enjoy the lat­est Google exper­i­ment designed for Chrome. One Hun­dred Thou­sand Stars is an inter­ac­tive map of space includ­ing the loca­tions of—you guessed it—more than 100,000 stars.

Ren­dered in three dimen­sions, our know­able, mapped galaxy is both stag­ger­ing­ly vast and easy to nav­i­gate. With imagery and data from NASA and the Euro­pean Space Agency, Google’s Chrome Work­shop built a 3D mod­el of our lit­tle cor­ner of the uni­verse.

You can pre­view One Hun­dred Thou­sand Stars above. Or you can enter the map, click on the upper left cor­ner, and take a tour of your own. You’ll start just beyond the stars that astronomers have stud­ied and named. Swipe all the way into our own solar sys­tem. The first thing you’ll notice is that Plu­to isn’t includ­ed, invit­ing a new mnemon­ic for the plan­et names (My Very Earnest Moth­er Just Served Us Nec­tarines?). That hazy cloud about a light year from the sun is the Oort Cloud, a mass of comets that’s thought to mark the out­er edge of the sun’s grav­i­ta­tion­al pull.

Swipe out a bit to see 87 rel­a­tive­ly near­by stars. Click on their names to read about them. Sir­ius is the bright­est in the night sky, part­ly because of its own lumi­nos­i­ty but also because it is com­par­a­tive­ly close to Earth. Vega is so well stud­ied that its bright­ness is used as the base­line to clas­si­fy stars accord­ing to their col­or.

Swipe out fur­ther for a galac­tic view of the Milky Way. It appears as a beau­ti­ful illu­mi­nat­ed disc cen­tered around a bright bulge. This shape is called the Galac­tic Plane. Click and drag to tilt the disc this way and that. Total­ing to some 400 bil­lion stars and as many plan­ets, the Milky Way does in fact bulge at its cen­ter, though astronomers think that the true core is real­ly an intense black hole.

Notice the tiny icon to “Tog­gle Spec­tral Index” up in the left cor­ner. On one set­ting, each cloud is pix­i­lat­ed to high­light its col­or (a key iden­ti­fi­er for astronomers).

Here’s where it helps to know a lit­tle about stars and how they form. Stars begin as clouds of most­ly hydro­gen, becom­ing grad­u­al­ly so dense through the process of nuclear fusion that even grav­i­ty can­not make them fly apart.

The amount of light a star gives off is mea­sured as dif­fer­ent col­ors and tem­per­a­tures. “Hot­ter” stars are younger and give off more blue light, and so are indi­cat­ed as blue. “Cool” stars are old­er, give off less blue light, and are indi­cat­ed as red.

By the way, the music behind One Hun­dred Thou­sand Stars is by Sam Hulick, whose music gamers may rec­og­nize  from Mass Effect.

Adam Savage (Host of MythBusters) Explains How Simple Ideas Become Great Scientific Discoveries

A good TED talk is like a com­mer­cial for a great idea. There might not be much meat to sink into, but like any good ad agency, TED has its own unique for­mu­la for mak­ing even the most eso­teric sub­ject grab­by.

Who, after all, would have thought that a video of a British guy lec­tur­ing about how schools kill cre­ativ­i­ty would get more than 8 mil­lion hits? Evi­dent­ly the folks at TED did, and were they ever right.

Good TED talks come in a few fla­vors. That British guy I men­tioned? Sir Ken Robinson’s talk about con­tem­po­rary edu­ca­tion is one of TED’s best pol­i­cy cri­tique talks (and its most pop­u­lar over­all). There are also the per­son­al sto­ries that com­pel and the demon­stra­tions of great new ideas.

This talk by actor and edu­ca­tor Adam Sav­age might fall into more than one of those buck­ets. In the video above, Savage—who designed mod­els for two Star Wars movies and hosts Myth­busters on the Dis­cov­ery Channel—talks plain and sim­ple about some of humanity’s most amaz­ing sci­en­tif­ic dis­cov­er­ies. He walks us through how Eratos­thenes cal­cu­lat­ed the Earth’s cir­cum­fer­ence more than 2000 years ago and how Hip­poly­te Fizeau mea­sured the speed of light in the mid-1880s.

These two men used noth­ing more than their own brains and a few rel­a­tive­ly sim­ple tools to make aston­ish­ing­ly accu­rate obser­va­tions. It’s stuff we already know, but in true TED style Sav­age makes the whole thing rev­e­la­to­ry and inspir­ing.

“What hap­pens when you think about the dis­cov­er­ies and what they were think­ing is you under­stand that they were not so dif­fer­ent from us,” Sav­age says. “The peo­ple who made these dis­cov­er­ies just thought a lit­tle bit hard­er about what they were look­ing at. And they were a lit­tle bit more curi­ous.”

Savage’s video is part of TEDEd’s Lessons Worth Shar­ing, which comes bun­dled with oth­er videos and exer­cis­es that teach­ers can use to dis­cuss the notion that sim­ple ideas can lead to sci­en­tif­ic dis­cov­ery.

It’s also a very good  com­mer­cial for curios­i­ty. Sev­en and a half min­utes pro­mot­ing curios­i­ty. Take a look. Curios­i­ty, as Sav­age says, can change the world.

Noam Chomsky Explains Where Artificial Intelligence Went Wrong

While pop­u­lar­ly known for his pierc­ing and relent­less cri­tiques of U.S. for­eign pol­i­cy and eco­nom­ic neolib­er­al­ism, Noam Chom­sky made his career as a researcher and pro­fes­sor of lin­guis­tics and cog­ni­tive sci­ence. In his 50 years at MIT he earned the appel­la­tion “the father of mod­ern lin­guis­tics” and—after over­turn­ing B.F. Skinner’s behav­ior­ist paradigm—founder of the “cog­ni­tive rev­o­lu­tion.” But these are labels the self-effac­ing Chom­sky rejects, in his char­ac­ter­is­ti­cal­ly under­stat­ed way, as he rejects all tri­umphal­ist nar­ra­tives that seem to promise more than they deliv­er.

Such is the case with Arti­fi­cial Intel­li­gence. The term, coined in 1956 by com­put­er sci­en­tist John McCarthy, once described the opti­mism with which the sci­en­tif­ic com­mu­ni­ty pur­sued the secrets of human cog­ni­tion in order to map those fea­tures onto machines. Opti­mism has turned to puz­zle­ment, ambiva­lence, or in Chomsky’s case out­right skep­ti­cism about the mod­els and method­olo­gies embraced by the field of AI.

Nev­er par­tic­u­lar­ly san­guine about the prospects of unlock­ing the “black box” of human cog­ni­tion through so-called “asso­ci­a­tion­ist” the­o­ries, Chom­sky has recent­ly become even more crit­i­cal of the sta­tis­ti­cal mod­els that have come to dom­i­nate so many of the sci­ences, though he is not with­out his crit­ics. At an MIT sym­po­sium in May of last year, Chom­sky expressed his doubts of a method­ol­o­gy Nobel-win­ning biol­o­gist Syd­ney Bren­ner has called “low input, high through­put, no out­put sci­ence.”

Recent­ly Yarden Katz, an MIT grad­u­ate stu­dent in Cog­ni­tive Sci­ences, sat down with Chom­sky to dis­cuss the prob­lems with AI as Chom­sky sees them. Katz’s com­plete inter­view appeared this month in The Atlantic. He also video­taped the inter­view and post­ed clips to his Youtube chan­nel. In the clip above, Katz asks Chom­sky about “for­got­ten method­olo­gies in arti­fi­cial intel­li­gence.” Chom­sky dis­cuss­es the shift toward prac­ti­cal appli­ca­tion in engi­neer­ing and com­put­ing tech­nol­o­gy, which “direct­ed peo­ple away from the orig­i­nal ques­tions.” He also express­es the opin­ion that the orig­i­nal work was “way too opti­mistic” and assumed too much from the lit­tle data avail­able, and he describes how “throw­ing a sophis­ti­cat­ed machine” at the prob­lem leads to a “self-rein­forc­ing” def­i­n­i­tion of suc­cess that is at odds with sci­en­tif­ic dis­cov­ery.

In the clip below, Chom­sky dis­cuss­es a new field in sys­tems biol­o­gy called “Con­nec­tomics,” an attempt to map the wiring of all the neu­rons in the brain—an endeav­or prick­ly biol­o­gist Syd­ney Bren­ner calls “a form of insan­i­ty.” Katz asks if the “wiring dia­gram” of the brain would pro­vide “the right lev­el of abstrac­tion” for under­stand­ing its work­ings.

The inter­view is worth read­ing, or watch­ing, in full, espe­cial­ly for stu­dents of neu­ro­science or psy­chol­o­gy. Chom­sky dis­cuss­es the work of his one­time col­league David Marr, whose posthu­mous­ly pub­lished book Vision has had an enor­mous influ­ence on the field of cog­ni­tive sci­ence. Chom­sky also prais­es the work of Randy Gal­lis­tel, who argues that devel­op­ments in cog­ni­tive and infor­ma­tion sci­ence will trans­form the field of neu­ro­science and over­turn the par­a­digms embraced by ear­ly researchers in AI. While this is an excit­ing time to be a cog­ni­tive sci­en­tist, it seems, per­haps, a dif­fi­cult time to be a pro­po­nent of Arti­fi­cial Intel­li­gence, giv­en the com­plex­i­ties and chal­lenges the field has yet to meet suc­cess­ful­ly.

Richard Feynman Talks Physics with Fred Hoyle in Take the World From Another Point of View, 1973

The famous Amer­i­can physi­cist Richard Feyn­man used to take hol­i­days in Eng­land. His third wife, Gweneth Howarth, was a native of West York­shire, so every year the Feyn­man fam­i­ly would vis­it her home­town of Rip­pon­den or the near­by ham­let of Mill Bank.

In 1973 York­shire pub­lic tele­vi­sion made a short film of the Nobel lau­re­ate while he was there. The result­ing film, Take the World From Anoth­er Point of View, was broad­cast in Amer­i­ca as part of the PBS Nova series. The doc­u­men­tary fea­tures a fas­ci­nat­ing inter­view, but what sets it apart from oth­er films on Feyn­man is the inclu­sion of a live­ly con­ver­sa­tion he had with the emi­nent British astro­physi­cist Fred Hoyle.

A native York­shire­man, Hoyle did ground­break­ing the­o­ret­i­cal work on the syn­the­sis of ele­ments in stars and was a lead­ing pro­po­nent of the Steady State the­o­ry of cos­mol­o­gy. In the film, the British astro­physi­cist and the Amer­i­can par­ti­cle physi­cist walk down to the local pub, Rip­pon­den’s his­toric Old Bridge Inn, for a live­ly con­ver­sa­tion on physics and the nature of sci­en­tif­ic dis­cov­ery. You can read along with a tran­script of the film at the Cal­tech Web site.

Watch James Burke’s TV Series Connections, and Discover the Unexpected History of Innovation

Even if we did­n’t grow up as sci­ence fans, all of us caught at least the occa­sion­al tele­vi­sion show on sci­ence his­to­ry. Some came expert­ly pro­duced. Oth­ers packed the infor­ma­tion to a very high den­si­ty (by TV’s stan­dards, at least). Oth­ers cracked jokes to keep our wits engaged. Oth­ers got us intrigued enough about a par­tic­u­lar dis­cov­ery to per­form our own fur­ther research at the library or on the inter­net. But those of us who came of age dur­ing a run of one of James Burke’s Con­nec­tionsseries got all of that at once, exe­cut­ed on a high­er plane, and with quite dif­fer­ent philo­soph­i­cal premis­es. Design­ing each of his pro­grams to exam­ine a dif­fer­ent nexus between sev­er­al ele­ments of sci­ence, nature, and  engi­neer­ing, Burke premis­es these nar­ra­tives on the insep­a­ra­bil­i­ty of human inge­nu­ity, his­tor­i­cal coin­ci­dence, and sheer acci­dent. How, for instance, did we end up in a world of film pro­jec­tors (cur­rent­ly being dis­placed by dig­i­tal pro­jec­tors though they may be)? For the answer, Burke argues, you’ve got to start with medieval cas­tle for­ti­fi­ca­tions. Then you work your way through can­nons, map­ping, lime­light, bil­liard-ball ivory, gun­cot­ton, the zooprax­is­cope, Morse code, and the phono­graph. These tech­no­log­i­cal threads all con­verge to give us the cin­e­mat­ic expe­ri­ence we enjoy today — or enjoyed in 1978, any­way.

If you enjoyed that episode of Con­nec­tions back then, know that you can now relive it on a Youtube chan­nel ded­i­cat­ed to Burke and his shows. If you nev­er watched any in the first place, you can now catch up on not just the ten episodes of the orig­i­nal Con­nec­tions, but 1994’s twice-as-long Con­nec­tions2, and the final series, 1997’s Con­nec­tions3I rec­om­mend begin­ning at the begin­ning, with Con­nec­tions’ first episode, “The Trig­ger Effect,” embed­ded above. It gets you into the mind­set of Burke’s “alter­na­tive view of change” by break­ing down and illus­trat­ing the very con­cept of human reliance on com­plex­ly con­nect­ed net­works. The pro­gram’s clear and fast-mov­ing but no-stone-unturned method­ol­o­gy of expla­na­tion takes you through the New York Black­out of 1965, ancient Egypt­ian agri­cul­ture, and the oil fields of Kuwait. Reach the end of the third series, and you wind up learn­ing just how much the Eif­fel Tow­er has to do with the Elgin Mar­bles, Ben­jamin Franklin, Lon­don Bridge, and the ZIP code. Burke empha­sizes that none of the his­tor­i­cal agents involved in all these scat­tered small inno­va­tions that enabled the big ones — the ones with such effects on our mod­ern lives — could have planned for things to go the way they did. His sto­ries thus grant us more than a bit of humil­i­ty about pre­dict­ing the inno­va­tions of the future, built as they will be atop the kind of com­plex­i­ty that not even Con­nec­tions ever described.

The Writer Who Couldn’t Read … And What That Tells Us About the Brain

It hap­pened sud­den­ly one day. Howard Engel, a Cana­di­an mys­tery writer, woke up and real­ized he could­n’t read the dai­ly news­pa­per, let alone his own nov­els.

Time-Lapse Film of the Space Shuttle Endeavor’s Final Journey Through the Narrow Streets of Los Angeles

Res­i­dents of Los Ange­les had a once-in-a-life­time oppor­tu­ni­ty last week to see the Space Shut­tle Endeav­or crawl through the streets of their city. It was a sur­re­al sight. Some folks could even look out their liv­ing-room win­dow and see a mas­sive space ship rolling by.

The recent­ly decom­mis­sioned shut­tle arrived in Los Ange­les on Sep­tem­ber 20, pig­gy­backed on top of a Boe­ing 747. Last thurs­day it embarked on an ardu­ous 12-mile jour­ney to its new home at the Cal­i­for­nia Sci­ence Cen­ter, where it will go on pub­lic dis­play begin­ning Octo­ber 30. It took three days to make the trip from the air­port to Expo­si­tion Park as the 85-ton orbiter, with a wingspan of 78 feet, was guid­ed though a num­ber of extreme­ly tight spots atop a com­put­er-con­trolled trans­porter oper­at­ed by NASA. The shut­tle arrived at the sci­ence cen­ter with­out a scratch on Sun­day. The whole oper­a­tion cost about $10 mil­lion.

Stephen Fry Friday: His Musings on Life, Swearing, Shakespeare, Nanoscience & More

Stephen Fry is a man of many tal­ents. He’s a nov­el­ist, con­trib­u­tor to news­pa­pers and mag­a­zines, TV per­son­al­i­ty, come­di­an, pod­cast­er, lin­guist of sorts. And accord­ing to his Twit­ter pro­file, he’s also a “Lord of Dance, Prince of Swimwear & Blog­ger.” In short, Stephen Fry cov­ers a lot of ground, and, through­out the years, we’ve shown you Fry opin­ing on many sub­jects. But you can’t real­ly appre­ci­ate his intel­lec­tu­al range until you’ve seen his mus­ings placed next to one anoth­er. So we’re pro­claim­ing today “Stephen Fry Fri­day” and we’re pre­sent­ing our favorite Fry clips from years past. We start above with Fry’s take on “The Joys of Swear­ing” and the rest fol­lows:

The Strange New World of Nanoscience

What is nano? And how will nanoscience shape our future? It’s all explained in a snap­py 17 minute video —  NANO YOU — that Fry nar­rat­ed for Cam­bridge Uni­ver­si­ty.

What I Wish I Knew When I Was 18 

It’s a peren­ni­al fan favorite — Fry reflect­ing on his life, all 55 years of it, and offer­ing up life lessons to young­sters. Truth be told, old­er folks will get some­thing out of this video too.

On Phi­los­o­phy and the Impor­tance of Unbe­lief

Get­ting into the nit­ty grit­ty of phi­los­o­phy, Fry gives us one more life les­son: If you assume there’s no after­life, you’ll like­ly have a fuller, more enrich­ing life.

A Kinet­ic Take on Lan­guage

For a brief time in 2008, Fry pro­duced a series of pod­casts – called “Pod­grams” – that drew on his writ­ings, speech­es and col­lec­tive thoughts. In one episode, he med­i­tat­ed on lan­guage — the Eng­lish lan­guage, his own lan­guage, Barthes, Chom­sky, and Pinker — and then Matthew Rogers took that med­i­ta­tion and ran with it, pro­duc­ing a “kinet­ic typog­ra­phy ani­ma­tion” that art­ful­ly illus­trates a six minute seg­ment of Fry’s longer talk.
