Free Stanford Course Explains Particle Physics & the Large Hadron Collider

There’s big news com­ing out of Europe today. After 16 years and $10 bil­lion, the Large Hadron Col­lid­er (LHC) is final­ly begin­ning to col­lide sub­atom­ic par­ti­cles. If you’re won­der­ing what this all means, let me turn your atten­tion to a year­long course that we’re offer­ing in Stan­ford’s Con­tin­u­ing Stud­ies pro­gram (my day job). New Rev­o­lu­tions in Par­ti­cle Physics is taught by Leonard Susskind, one of the world lead­ing physi­cists, and it takes a deep look at new the­o­ries in par­ti­cle physics that emerged dur­ing the 1970s, and how they’re now being test­ed by the LHC. The first course overviews the basic con­cepts, and you can watch it on YouTube or iTunes. (The first lec­ture appears above.) The sec­ond course will be soon made avail­able online. The third course is just get­ting under­way in the class­room (you can enroll here if you live near Stan­ford), and we’ll even­tu­al­ly post that course online as well. You can find more physics cours­es in the Physics sec­tion of our large col­lec­tion of Free Online Cours­es.

UPDATE: As Maria, aka @brainpicker notes in the com­ments, CERN (which runs the LHC) hosts an archive of lec­tures, movies and col­li­sion videos, includ­ing some of this morning’s suc­cess­ful tests. More here.

For a Tiny Instant, Physicists Broke a Law of Nature

An intrigu­ing bit of news from the Yale Bul­letin. It begins:

For a brief instant, it appears, sci­en­tists at Brook haven Nation­al Lab­o­ra­to­ry on Long Island recent­ly dis­cov­ered a law of nature had been bro­ken.

Action still result­ed in an equal and oppo­site reac­tion, grav­i­ty kept the Earth cir­cling the Sun, and con­ser­va­tion of ener­gy remained intact. But for the tini­est frac­tion of a sec­ond at the Rel­a­tivis­tic Heavy Ion Col­lid­er (RHIC), physi­cists cre­at­ed a sym­me­try-break­ing bub­ble of space where par­i­ty no longer exist­ed.

You can read more about what went down here. And, if you want to brush up your physics, head over to the Physics sec­tion of our Free Online Course col­lec­tion. There you’ll find free physics cours­es from Yale, Stan­ford, MIT and oth­er fine insti­tu­tions of high­er learn­ing.

Einstein in 60 Seconds (or 40 Hours)

Big­Think asked Dr. Michio Kaku to sum up Ein­stein’s lega­cy in a nut­shell. Above, you get his attempt in a quick minute. Obvi­ous­ly, this is just begin­ning to scratch the sur­face, and know­ing you, you want to go deep­er. So here you go: Leonard Susskind, a world famous physi­cist, offered a series of six cours­es for Stan­ford Con­tin­u­ing Stud­ies, which traced the arc of mod­ern physics. It goes from New­ton to Black Holes. Nat­u­ral­ly a tour of mod­ern physics would­n’t be com­plete with­out spend­ing a good amount of time on Ein­stein, and that’s what Susskind does. One course (runs about 20 hours) is ded­i­cat­ed to Spe­cial Rel­a­tiv­i­ty (iTunes – YouTube) and the oth­er focus­es exclu­sive­ly on Ein­stein’s The­o­ry of Gen­er­al Rel­a­tiv­i­ty (iTunes — YouTube). This series of cours­es (all per­ma­nent­ly found in the Physics sec­tion of our Free Online Course col­lec­tion) has been enjoyed by view­ers across the world, and we (at Stan­ford) have recent­ly shipped CDs of the course to remote places with min­i­mal band­width, includ­ing Nepal and Afghanistan. For more on how to learn physics online (for free, of course), see our post: Mod­ern Physics: A Com­plete Intro­duc­tion.

Stars Orbiting Black Holes

Above, we bring you what astro­physi­cist Daniel Holz calls “one of the coolest movies in all of sci­ence.” What you see here is not exact­ly straight­for­ward. But it’s the work of UCLA astronomer Andrea Ghez, and it essen­tial­ly shows stars orbit­ing around a super­mas­sive black hole at the cen­ter of our galaxy over the past 15 earth years. Accord­ing to Holz, these orbits, filmed with the largest tele­scopes in the world on Mau­na Kea, are sim­ply “one of the best ways (short of the detec­tion of grav­i­ta­tion­al waves from black hole merg­ers) of con­firm­ing that black holes exist.” And it’s quite right­ly an “incred­i­ble feat of obser­va­tion­al astron­o­my.” For more, read Holz’s piece on Dis­cov­er’s Cos­mic Vari­ance blog. Anoth­er big thanks to Mike for pass­ing this one our way…

The Physics of a Quarterback’s Pass

A lighter piece for Super Bowl Sun­day. Yes, this clip isn’t exact­ly heady. And, yes, it botch­es some facts (archers appar­ent­ly shoot from 70 meters, not 20 yards). But, nonethe­less, it gives you the basic physics of Drew Brees’ pass­ing game. Brees will be play­ing QB for the New Orleans Saints tonight, and, as you’ll see, his accu­ra­cy is remark­able. Hat tip to Mike.

Einstein is Money


New­ton, Coper­ni­cus, Galileo, Bohr and many oth­er great sci­en­tists appear on paper cur­ren­cies from around the world. Note that you can click on each image to see it in a high­er res­o­lu­tion.

Modern Physics: A Free 6‑Course Introduction by Stanford’s Leonard Susskind

For the past two years, Stan­ford has been rolling out a series of cours­es (col­lec­tive­ly called Mod­ern Physics: The The­o­ret­i­cal Min­i­mum) that gives you a base­line knowl­edge for think­ing intel­li­gent­ly about mod­ern physics. The sequence, which moves from Isaac New­ton, to Albert Einstein’s work on the gen­er­al and spe­cial the­o­ries of rel­a­tiv­i­ty, to black holes and string the­o­ry, comes out of Stanford’s Con­tin­u­ing Stud­ies pro­gram. And the cours­es are all taught by Leonard Susskind, an impor­tant physi­cist who has engaged in a long run­ning “Black Hole War” with Stephen Hawk­ing. The final course, Sta­tis­ti­cal Mechan­ics, has now been post­ed on YouTube. The rest of the cours­es can be accessed imme­di­ate­ly below. (The cours­es also appear in our list of Free Online Physics Cours­es, a sub­set of our col­lec­tion, 1,700 Free Online Cours­es from Top Uni­ver­si­ties.) Six cours­es. Rough­ly 120 hours of con­tent. A com­pre­hen­sive tour of mod­ern physics. All in video. All free. Beat that.

The Bohr-Einstein Debates, Reenacted With Dog Puppets

Boing­Bo­ing is run­ning a piece this morn­ing on Chad Orzel’s new book, How to Teach Physics to Your Dog. It’s good stuff, and it reminds me that Orzel also recent­ly released a video that re-enacts the famous Bohr-Ein­stein debates, with, yes, dog pup­pets. You can watch above. Or, alter­na­tive­ly, you can get it on YouTube in three parts: here, here and here.
