We Are Here: The Pale Blue Dot


Let Carl Sagan put every­thing – and I mean every­thing – in per­spec­tive for you …

The Search For Hidden Dimensions

An impor­tant Amer­i­can string the­o­rist, Bri­an Greene has­n’t shied away from bring­ing heady the­o­ret­i­cal physics to the broad­er pub­lic. His 1999 best­selling book, The Ele­gant Uni­verse, intro­duced string the­o­ry to non spe­cial­ists, and it was lat­er adapt­ed into a three hour, Emmy award-win­ning tele­vi­sion series by NOVA. (You can buy it on DVD, or sim­ply watch it online here.) Now, on RichardDawkins.Net, Greene hosts a short video that takes us into the spec­u­la­tive world of “hid­den dimen­sions.” If borne out, these the­o­ries could entire­ly reframe our under­stand­ing of the Big Bang and where our world fits into the larg­er cos­mos. You can find more videos along these lines on RichardDawkins.net, and also on his relat­ed YouTube Chan­nel (which hap­pens to appear in our col­lec­tion of Intel­li­gent YouTube Chan­nels).

What the Big Spill Means for Sea Life

The BP oil spill has tak­en us into some unchart­ed waters. We still don’t know how much oil is pour­ing into the ocean each day. (Here’s the lat­est esti­mate.) Nor do we know the exact toll this dis­as­ter will take on the ecosys­tem of the Gulf. We only know that things are mov­ing in a very dis­cour­ag­ing direc­tion. Above Dr. Lisa Sua­toni, a marine expert at the Nat­ur­al Resources Defense Coun­cil, answers some basic ques­tions: “Where is the oil?  What is it harm­ing?  What unique habi­tats and bio­log­i­cal diver­si­ty are at risk?” You can keep abreast of these issues at the NRD­C’s Dis­as­ter in the Gulf blog, and also help save Gulf Coast wildlife by mak­ing a dona­tion to the NRDC.

Space Shuttle Discovery: From Prep to Launch in Three Minutes

Three min­utes of time lapse video dis­tills six weeks of footage show­ing the Space Shut­tle Dis­cov­ery get­ting ready for launch. It moves you from the Orbiter Pro­cess­ing Facil­i­ty to the launch­ing pad, and every­where in between. Air & Space has more details on the whole she­bang. Props to Joshua for send­ing this video our way.

Martin Gardner: A Video Remembrance

This past week­end, Mar­tin Gard­ner, a gift­ed and pro­lif­ic pop­u­lar­iz­er of math­e­mat­ics and sci­ence, passed away at 95. Dur­ing his life, Gard­ner pub­lished more than 70 books and wrote the pop­u­lar “Math­e­mat­i­cal Games” col­umn for Sci­en­tif­ic Amer­i­can mag­a­zine for 25 years. As The New York Times obit notes, his math­e­mat­i­cal writ­ings “intrigued a gen­er­a­tion of math­e­mati­cians,” and he earned the admi­ra­tion of many lead­ing intel­lec­tu­als, includ­ing W. H. Auden, Arthur C. Clarke, Stephen Jay Gould, Vladimir Nabokov, and Carl Sagan. Not bad for a man who nev­er took a col­lege-lev­el math course. Above, you will find a 46-minute video pro­file of Gard­ner from David Suzuk­i’s CBC tele­vi­sion series “The Nature of Things.” It’s a great intro­duc­tion to Gard­ner and his unique approach to math and sci­ence.

Thanks goes to Mike for send­ing the video our way.


Can Monkeys Talk?

If we believe that Homo sapi­ens (a.k.a. peo­ple) and mon­keys evolved from a com­mon ances­tor, then it makes sense to ask: Can mon­keys use lan­guage like we do? Do they make mere sounds? Or do they use spe­cif­ic sounds to com­mu­ni­cate a range of dif­fer­ent intend­ed things? Robert Sey­far­th, a pro­fes­sor at the Uni­ver­si­ty of Penn­syl­va­nia, uses the case of the Vervet Mon­keys to answer these ques­tions. You can read more about his work in The New York Times.

James Joyce Encoded in Venter’s Artificial Life

You may have heard the news last week: J. Craig Ven­ter and a team of sci­en­tists cre­at­ed the first liv­ing organ­ism – a “syn­thet­ic cell” – by way of a com­put­er-gen­er­at­ed genome. We’re now see­ing the begin­nings of arti­fi­cial life. And it’s a big sto­ry, with many far-reach­ing impli­ca­tions. But where does James Joyce fit into this pic­ture? Let me add this lit­tle fac­toid to the mix: Accord­ing to The Chris­t­ian Sci­ence Mon­i­tor, Ven­ter’s team insert­ed DNA water­mark codes into the genome so that they can dis­tin­guish between nat­ur­al and syn­thet­ic bac­te­ria mov­ing for­ward. And when this code is trans­lat­ed into Eng­lish, it will “spell out the names of the 46 researchers who helped with the project, quo­ta­tions from James Joyce, physi­cist Richard Feyn­man and J. Robert Oppen­heimer, and a URL that any­one who deci­phers the code can e‑mail.” Lots of smarts packed into the tini­est of pack­ages.

UPDATE: The quotes in water­mark appar­ent­ly read: “TO LIVE, TO ERR, TO FALL, TO TRIUMPH, TO RECREATE LIFE OUT OF LIFE.” — James Joyce’s A Por­trait of the Artist as a Young Man; “SEE THINGS NOT AS THEY ARE, BUT AS THEY MIGHT BE.”-A quote from an Oppen­heimer biog­ra­phy, Amer­i­can Prometheus; “WHAT I CANNOT BUILD, I CANNOT UNDERSTAND.” — Richard Feyn­man.

Iron Man: The Science in Science Fiction

As Robert Bly not­ed in his book, The Sci­ence in Sci­ence Fic­tion, some of the most intrigu­ing sci­en­tif­ic ideas have orig­i­nat­ed not in labs, but in sci-fi books and movies. With Iron Man 2 hit­ting the screens, Sid­ney Perkowitz, a physi­cist at Emory Uni­ver­si­ty, talks about whether the sci­ence in the new pop movie has any roots in sci­en­tif­ic real­i­ty – or, for that mat­ter, whether it might inspire any new sci­en­tif­ic think­ing down the road. He offers his thoughts above. In addi­tion to writ­ing Hol­ly­wood Sci­ence: Movies, Sci­ence and the End of the World, Perkowitz sits on the advi­so­ry board of the Sci­ence and Enter­tain­ment Exchange, a Nation­al Acad­e­my of Sci­ences pro­gram that tries to bring more sci­en­tif­ic accu­ra­cy to mass mar­ket enter­tain­ment.

Thanks Nicole for the tip on this one.
