YouTube’s Trendspotting Tuesday focused this past week on the growing number of videos that can teach you a foreign language (for free, of course). Among the 12 video collections featured here, you’ll find ones that offer lessons in French, Spanish, Modern Greek, Latin, Japanese and Swahili, among others. They also highlight clips that demonstrate how to write Arabic. (Find the first clip below.) Straightaway, you’ll notice that these videos have a home brewed feel to them, and they’re not necessarily as substantive as what you can get for free via podcast. (See our large Foreign Language Lesson Podcast Collection). But, at least when it comes to demonstrating something visual (such as how to write Arabic) they have their purpose.
(P.S. With the video below, I have no idea how much the “instructor” actually knows about Arabic. The point isn’t to pass this off as a definitive source of knowledge, but more to show how the video platform is being used.)
By now, most everyone knows that Randy Pausch sadly died of pancreatic cancer last week. And, if you have an internet pulse, you’re already acquainted with his lecture that caught the public imagination last year: Really Achieving Your Childhood Dreams. What you may not have seen is the short, six-minute speech Pausch made at Carnegie Mellon’s graduation in late May — a short two months ago. The philosophy here remains the same. The pitch is just shorter and to the point. It’s added to our YouTube playlist. Here it goes:
1200 people live in Antarctica during the summer, and about 200 in winter. Assuming that you’re not among them, we’ve posted this time lapse video to show you what you’re missing:
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).

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:

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.
