Here is Jimmy Wales, Wikipedia’s founder, being interviewed after Google debuted Knol. Interesting that his first thought is that users should copy Knol content and bring it to Wikipedia … :
Randy Pausch, the computer science professor from Carnegie Mellon University whose “Last Lecture” caught the public imagination, has died of pancreatic cancer. Thanks partly to a Wall Street Journal article written last September, the public discovered the remarkably upbeat and uplifting lecture Pausch gave soon after getting diagnosed. Titled “Really Achieving Your Childhood Dreams” (see video below, or download on iTunes here), the lecture became a media sensation and went viral across the web. And it served as the basis for Pausch’s bestelling book, The Last Lecture. If you haven’t seen the video, give it your time. It will teach you something more valuable than anything else we serve up here.
Last December, Google announced that it was testing a new content initiative — dubbed “Knol” — intended to rival Wikipedia. The fruits of their labor are now live (in beta), available for all to see.
As we mentioned in our initial piece, Knol caters to the individual author/expert, not to the wisdom of crowds (à la Wikipedia). Each encyclopedia entry is generally written, edited, and revised by one individual. The author reigns supreme here. But that doesn’t mean that Wikipedia’s collaborative approach is being entirely abandoned.
Google’s model leaves ample room for collaborative writing. It keeps open the possibility that multiple authors will write an encyclopedia entry. And, they allow for “moderated collaboration” — meaning that “any reader can make suggested edits to a knol which the author may then choose to accept, reject, or modify before these contributions become visible to the public.” Collaboration is built into Google’s model. It’s just not taken to an extreme conclusion. (Get more info on the positioning of Knol here.)
Knol is not the only content platform trying to strike a balance between the author and mass collaboration. In June, Encyclopedia Britannica launched a beta of a new online encyclopedia that takes “a collaborative-but-not-democratic approach” to producing knowledge. Users can make contributions to a growing storehouse of knowledge. But whether these contributions get accepted remains up to the experts and editors. (“At the new Britannica site, we will welcome and facilitate the increased participation of our contributors, scholars, and regular users, but we will continue to accept all responsibility of what we write under our name. We are not abdicating our responsibility as publishers or burying it under the now-fashionable “wisdom of the crowds.”)
I have little doubt that the Google and Britannica models will generate some solid encyclopedia entries. That’s a safe bet. But whether these encyclopedias will ever become as comprehensive as Wikipedia, or as widely used, is another question. And the same holds true for whether the content will generally be qualitatively better than what Wikipedia has to offer. When Google first announced Knol last December, I voiced my doubts. Now that the rubber is finally hitting the road, we can see whether my skepticism is warranted (or not).
It’s 1940. The film is The Great Dictator, Charlie Chaplin’s famous satire of Nazi Germany. In this celebrated scene, Chaplin dances with a large globe with Richard Wagner’s Lohengrin Overture playing in the background.
Richard Muller teaches one of the most popular undergraduate courses at UC Berkeley: Physics for Future Presidents. You can watch it on YouTube (above). And now you can buy Muller’s new book. Just published by W.W. Norton, Physics for Future Presidents: The Science Behind the Headlines gives citizens the scientific knowledge they need to understand critical issues facing our society — is “Iran’s nascent nuclear capability … a genuine threat to the West,” are there “viable alternatives to fossil fuels that should be nurtured and supported by the government,” and should “nuclear power should be encouraged”? These issues (and more) get tackled here. For more info on the book, you can listen to a good interview conducted this morning (mp3) here in San Francisco.
Muller’s course, Physics for Future Presidents, has been added to our collection of Free Online Physics Courses, a subset of our collection, 1,700 Free Online Courses from Top Universities.

What’s the “theoretical minimum” for thinking intelligently about modern physics? Here’s your chance to find out. Below, you will find three courses (the first of eventually six) presented by Leonard Susskind, a Stanford physicist who helped conceptualize string theory and has waged a long-running “Black Hole War” with Stephen Hawking (see his new book on that subject here). Freely available on iTunes and YouTube (see below), these video lectures trace the beginnings of modern theoretical physics, taking you from Isaac Newton (or Newtonian Mechanics) to Albert Einstein’s work on the general and special theories of relativity. Notably, these courses were originally presented within Stanford’s Continuing Studies program, which means that the content was pitched to an audience much like you — that is, smart people who don’t necessarily have an extensive knowledge of physics. Watch the video below — the first lecture that kicks off the series of courses — and you will see what I mean.
Finally, in case you’re wondering, the next three courses (covering quantum mechanics, electromagnetism, cosmology, black holes, and more) will be presented this coming academic year and, once taped, we will give you a heads up. Sign up for our RSS Feed and you will be sure to get an update. Also see our collection of Free Online Courses for many more courses along these lines.

In 2006–2007, Susskind taped a separate series of lectures on Quantum Mechanics. You can download them as free video lectures as well:

Joerg, one of our readers, wrote us rather joyfully and declared: “Today I found the site of my dreams: Supposedly most of the greatest new documentaries can be watched online” and they’re “financed by ads.” The site is called SnagFilms, and indeed, it finds “the world‘s most compelling documentaries, whether from established heavyweights or first-time filmmakers, and mak[es] them available to the wide audience these titles deserve.” In exchange for making the films free, you do have to sit through some ads, but it is perhaps a small price to pay. Below we have posted Super Size Me, the 2004 documentary by Morgan Spurlock, which offers some startling commentary on the fast food industry. Other notable titles include the 2004 rock documentary Dig!, Under Our Skin, and Run Granny Run. You can see their full collection here.
NOTE: You can find this film in our collection of free online movies.

How does modern neuroscience make sense of the current McCain-Obama race? Have a listen to Christopher Lydon’s fascinating conversation with George Lakoff, a professor of cognitive linguistics at the University of California, Berkeley (iTunes — MP3 — Feed — Web Site).
Lakoff is the author of the new book, The Political Mind: Why You Can’t Understand 21st-Century American Politics with an 18th-Century Brain, and he’s essentially arguing here that the Democrats have traditionally framed their arguments with a cold rationalism .… and lost … while the Republicans have grounded theirs in a kind of emotionalism that squares with how the brain functions. But, with Obama, things are starting to change…
In Radiohead’s new video for “House of Cards”, no cameras or lights were used. Instead “3D plotting technologies collected information about the shapes and relative distances of objects.” And the video was made entirely with visualizations of that data. You can watch the video below and find out more about the making of the video here.
