An imporÂtant AmerÂiÂcan string theÂoÂrist, BriÂan Greene hasÂn’t shied away from bringÂing heady theÂoÂretÂiÂcal physics to the broadÂer pubÂlic. His 1999 bestÂselling book, The EleÂgant UniÂverse, introÂduced string theÂoÂry to non speÂcialÂists, and it was latÂer adaptÂed into a three hour, Emmy award-winÂning teleÂviÂsion series by NOVA. (You can buy it on DVD, or simÂply watch it online here.) Now, on RichardDawkins.Net, Greene hosts a short video that takes us into the specÂuÂlaÂtive world of “hidÂden dimenÂsions.” If borne out, these theÂoÂries could entireÂly reframe our underÂstandÂing of the Big Bang and where our world fits into the largÂer cosÂmos. You can find more videos along these lines on RichardDawkins.net, and also on his relatÂed YouTube ChanÂnel (which hapÂpens to appear in our colÂlecÂtion of IntelÂliÂgent YouTube ChanÂnels).
The BP oil spill has takÂen us into some unchartÂed waters. We still don’t know how much oil is pourÂing into the ocean each day. (Here’s the latÂest estiÂmate.) Nor do we know the exact toll this disÂasÂter will take on the ecosysÂtem of the Gulf. We only know that things are movÂing in a very disÂcourÂagÂing direcÂtion. Above Dr. Lisa SuaÂtoni, a marine expert at the NatÂurÂal Resources Defense CounÂcil, answers some basic quesÂtions: “Where is the oil? What is it harmÂing? What unique habiÂtats and bioÂlogÂiÂcal diverÂsiÂty are at risk?” You can keep abreast of these issues at the NRDÂC’s DisÂasÂter in the Gulf blog, and also help save Gulf Coast wildlife by makÂing a donaÂtion to the NRDC.
Three minÂutes of time lapse video disÂtills six weeks of footage showÂing the Space ShutÂtle DisÂcovÂery getÂting ready for launch. It moves you from the Orbiter ProÂcessÂing FacilÂiÂty to the launchÂing pad, and everyÂwhere in between. Air & Space has more details on the whole sheÂbang. Props to Joshua for sendÂing this video our way.
This past weekÂend, MarÂtin GardÂner, a giftÂed and proÂlifÂic popÂuÂlarÂizÂer of mathÂeÂmatÂics and sciÂence, passed away at 95. DurÂing his life, GardÂner pubÂlished more than 70 books and wrote the popÂuÂlar “MathÂeÂmatÂiÂcal Games” colÂumn for SciÂenÂtifÂic AmerÂiÂcan magÂaÂzine for 25 years. As The New York Times obit notes, his mathÂeÂmatÂiÂcal writÂings “intrigued a genÂerÂaÂtion of mathÂeÂmatiÂcians,” and he earned the admiÂraÂtion of many leadÂing intelÂlecÂtuÂals, includÂing W. H. Auden, Arthur C. Clarke, Stephen Jay Gould, Vladimir Nabokov, and Carl Sagan. Not bad for a man who nevÂer took a colÂlege-levÂel math course. Above, you will find a 46-minute video proÂfile of GardÂner from David SuzukÂi’s CBC teleÂviÂsion series “The Nature of Things.” It’s a great introÂducÂtion to GardÂner and his unique approach to math and sciÂence.
Thanks goes to Mike for sendÂing the video our way.
If we believe that Homo sapiÂens (a.k.a. peoÂple) and monÂkeys evolved from a comÂmon ancesÂtor, then it makes sense to ask: Can monÂkeys use lanÂguage like we do? Do they make mere sounds? Or do they use speÂcifÂic sounds to comÂmuÂniÂcate a range of difÂferÂent intendÂed things? Robert SeyÂfarÂth, a proÂfesÂsor at the UniÂverÂsiÂty of PennÂsylÂvaÂnia, uses the case of the Vervet MonÂkeys to answer these quesÂtions. You can read more about his work in The New York Times.
You may have heard the news last week: J. Craig VenÂter and a team of sciÂenÂtists creÂatÂed the first livÂing organÂism – a “synÂthetÂic cell” – by way of a comÂputÂer-genÂerÂatÂed genome. We’re now seeÂing the beginÂnings of artiÂfiÂcial life. And it’s a big stoÂry, with many far-reachÂing impliÂcaÂtions. But where does James Joyce fit into this picÂture? Let me add this litÂtle facÂtoid to the mix: AccordÂing to The ChrisÂtÂian SciÂence MonÂiÂtor, VenÂter’s team insertÂed DNA waterÂmark codes into the genome so that they can disÂtinÂguish between natÂurÂal and synÂthetÂic bacÂteÂria movÂing forÂward. And when this code is transÂlatÂed into EngÂlish, it will “spell out the names of the 46 researchers who helped with the project, quoÂtaÂtions from James Joyce, physiÂcist Richard FeynÂman and J. Robert OppenÂheimer, and a URL that anyÂone who deciÂphers the code can e‑mail.” Lots of smarts packed into the tiniÂest of packÂages.
UPDATE: The quotes in waterÂmark apparÂentÂly read: “TO LIVE, TO ERR, TO FALL, TO TRIUMPH, TO RECREATE LIFE OUT OF LIFE.” — James Joyce’s A PorÂtrait of the Artist as a Young Man; “SEE THINGS NOT AS THEY ARE, BUT AS THEY MIGHT BE.”-A quote from an OppenÂheimer biogÂraÂphy, AmerÂiÂcan Prometheus; “WHAT I CANNOT BUILD, I CANNOT UNDERSTAND.” — Richard FeynÂman.
As Robert Bly notÂed in his book, The SciÂence in SciÂence FicÂtion, some of the most intriguÂing sciÂenÂtifÂic ideas have origÂiÂnatÂed not in labs, but in sci-fi books and movies. With Iron Man 2 hitÂting the screens, SidÂney Perkowitz, a physiÂcist at Emory UniÂverÂsiÂty, talks about whether the sciÂence in the new pop movie has any roots in sciÂenÂtifÂic realÂiÂty – or, for that matÂter, whether it might inspire any new sciÂenÂtifÂic thinkÂing down the road. He offers his thoughts above. In addiÂtion to writÂing HolÂlyÂwood SciÂence: Movies, SciÂence and the End of the World, Perkowitz sits on the adviÂsoÂry board of the SciÂence and EnterÂtainÂment Exchange, a NationÂal AcadÂeÂmy of SciÂences proÂgram that tries to bring more sciÂenÂtifÂic accuÂraÂcy to mass marÂket enterÂtainÂment.
Thanks Nicole for the tip on this one.
