Math & Science Tutoring on YouTube

This comes to us via a tip from Twit­ter. The Khan Acad­e­my has now post­ed on YouTube over 800 videos (find a com­plete list here) that will teach stu­dents the ins-and-outs of alge­bra, geom­e­try, trigonom­e­try, cal­cu­lus, sta­tis­tics, finance, physics, eco­nom­ics and more. The clips have been record­ed by Salman Khan, a Har­vard Busi­ness School and MIT grad. And to give you a feel for them, we’ve post­ed above the first in a long sequence of lec­tures on dif­fer­en­tial equa­tions. (The remain­ing lec­tures can be found here.) This YouTube chan­nel, which now appears on our list, Intel­li­gent YouTube Video Col­lec­tions, is one of sev­er­al video sites that pro­vide free online tutor­ing via video. As men­tioned in the past, you can find online good video col­lec­tions ded­i­cat­ed to chem­istry and cal­cu­lus.

Armstrong’s Case for God

In recent years, we have seen a num­ber of books pub­lished that have made the case for athe­ism: Richard Dawk­in’s The God Delu­sion, Christo­pher Hitchens’ God Is Not Great, Sam Har­ris’ Let­ter to a Chris­t­ian Nation, and Daniel Den­net­t’s Break­ing the Spell: Reli­gion as a Nat­ur­al Phe­nom­e­non. It was almost as if a dam had bro­ken, and sud­den­ly a voice that had­n’t been heard in some time, at least not in the US, was let loose. The books hit hard, one after anoth­er, and they made their point. And now Karen Arm­strong, who has writ­ten more than 20 books on Islam, Judaism and Chris­tian­i­ty, offers a reply. Her new book pub­lished this week, The Case for God: What Reli­gion Real­ly Means, takes a his­tor­i­cal look at God and con­cludes that we mod­erns (athe­ists, evan­gel­i­cals and the rest) are work­ing with a facile con­cep­tion of God. And then she sug­gests an alter­na­tive way of see­ing things. You can get a taste for her think­ing in this NPR inter­view con­duct­ed this week: Lis­ten with the play­er below, or via these links (MP3 — iTunes — Stream):


Digital Archive of Vintage Television Commercials

adviewsThanks to Duke Uni­ver­si­ty, you can now access a dig­i­tal archive of vin­tage tele­vi­sion com­mer­cials dat­ing from the 1950s to the 1980s. Even­tu­al­ly, this col­lec­tion will fea­ture close to 12,000 dig­i­tized com­mer­cials, and it will let you see how Amer­i­ca’s tra­di­tion­al brands (IBM, Maxwell House, Amer­i­can Express, Avis, etc) evolved through the medi­um of main­stream com­mer­cial tele­vi­sion. You can learn more about this col­lec­tion called Adviews with this intro­duc­to­ry video or via the Adviews web­site, and you can watch the vin­tage com­mer­cials through iTunes. (Unfor­tu­nate­ly, I don’t see a way to access these clips via oth­er means. Sor­ry about that.) Via @LibrarySecrets

The Beatles Remastered: An Inside Look

bremasterOn Sep­tem­ber 9th, EMI released a remas­tered ver­sion of the entire Bea­t­les cat­a­logue — the first remix since 1987. And now the Bea­t­les are once again back on top of the charts. If you’re won­der­ing whether to buy the remas­tered ver­sions at all, or whether to buy the stereo or mono box sets (or some com­bi­na­tion of the two), or if you’re sim­ply won­der­ing what goes into remas­ter­ing the Fab Four’s com­plete body of work, then you will be inter­est­ed in this inter­view with Bea­t­les his­to­ri­an Kevin Howlett, who helped write the lin­er notes for the new releas­es. In this con­ver­sa­tion with NPR’s All Songs Con­sid­ered (MP3 — iTunes — RSS Feed), Howlett describes what the remas­ter­ing involved, and then com­pares the old ver­sions to the new ver­sions (both mono and stereo). When you’re done lis­ten­ing to this 20+ minute inter­view, you’ll have a much bet­ter sense of what this long-await­ed remas­ter­ing deliv­ers. You can lis­ten with the play­er below, or via the links post­ed above.

US Justice Department Looks to Restructure Google Books Settlement

The US Jus­tice Depart­ment offi­cial­ly weighed in today on the Google Books set­tle­ment with pub­lish­ers and authors. On the plus side for Google, the gov­ern­ment wants to see the project con­tin­ue because it has clear social ben­e­fits. On the down­side, the DOJ has con­cerns about antitrust and copy­right issues, and it’s look­ing for the deal to get restruc­tured. You can get more details in The Wall Street Jour­nal. It’s late. I’m out.

A quick heads up: Life­hack­er is high­light­ing today some new soft­ware (Win­dows only) that will let you down­load free access/public domain texts from Google Book Search and then turn them into neat PDF files. To get tips on how to use the soft­ware cre­at­ed by a third par­ty, not Google, head on over to Life­hack­er. I haven’t per­son­al­ly used the Down­loader, main­ly because I work on a Mac. If you try it out, let us know how the soft­ware works for you.

The End of Wall Street?: Michael Lewis

Here we are. One year after the fall of Lehman Broth­ers. And here we have Michael Lewis, the author of Liar’s Pok­er, talk­ing about his next book — The Big Short: Inside the Dooms­day Machine (2010) — that looks at those peo­ple who actu­al­ly under­stood that Wall Street was going to blow up. Most of the bank­ing com­mu­ni­ty did­n’t see it com­ing. (Hap­py anniver­sary Dick Fuld.) But a hand­ful saw the writ­ing on the wall and took the big short bet. You can get Lewis’ com­plete talk here.

Uranium Wars: A Free Audio Chapter

Just a quick fyi: Audible.com is giv­ing away a free chap­ter (in audio) from a new book, Ura­ni­um Wars: The Sci­en­tif­ic Rival­ry that Cre­at­ed the Nuclear Age (pre­view it on Ama­zon here). Writ­ten by Amir Aczel, a skilled pop­u­lar sci­ence writer, the book takes a close look at the sci­en­tists who dis­cov­ered the destruc­tive poten­tial of ura­ni­um and launched the begin­ning of the nuclear age. Since the book has been get­ting good reviews, I thought that I’d flag this free give­away. Also, as men­tioned here before, Audi­ble runs a reg­u­lar pro­mo­tion that will let you down­load a free audio­book of your choice (for exam­ple, Ura­ni­um Wars) if you start a 14 day free tri­al. Once the tri­al is over, you can con­tin­ue your Audi­ble sub­scrip­tion, or can­cel it, and still keep the free book. The choice is yours. You can ini­ti­ate that process here.

Philosophy Still Matters

Har­vard phi­los­o­phy pro­fes­sor Michael Sandel appeared on the Today Show this morn­ing, and got four min­utes to make the case for phi­los­o­phy. If you’re not famil­iar with him, Sandel is a very pop­u­lar Har­vard pro­fes­sor. Some 15,000 stu­dents have tak­en his cours­es over 30 years, and to get a feel for his teach­ing, you can watch his 30-minute lec­ture online. It’s called Jus­tice: A Jour­ney into Moral Rea­son­ing, and it’s one of the very few open lec­tures that Har­vard has put online. (A dis­ap­point­ment, I must say.) The lec­ture also oth­er­wise appears in our col­lec­tion of Free Uni­ver­si­ty Cours­es. Final­ly, I’d also encour­age you to lis­ten to the series of lec­tures that Sandel pre­sent­ed through the BBC. We fea­tured them here before, and we’re glad that Tamas, one of our read­ers, has remind­ed us of them.
