Because it seems to me that Brian sent the message to his whole addressbook, it follows that he probably wants people to talk about the shining project, and I am just going to do so.
This video describes itself as "non-public". I wonder whether it makes any difference when I embed it.
In this introductory video, Brian Greene says that he didn't have the satisfactory feeling of a "full understanding" of special relativity in the college courses, something I found surprising given his extremely high IQ and achievements. He needed mental images. Well, sometimes the right images are completely non-visual. As an instructor at my Prague Alma Mater used to say, but I only appreciated the real wisdom of the quasi-joke later: the best picture is an equation.
At any rate, if the video or words have already convinced you that it is a project you can't resist, you should
register to World Science U (click).It seems that some courses are already out there at WorldScienceU.COM.
You must try it because it looks pretty cool. For example, you click at "Science Unplugged" which is like a "preemptive" Physics Stack Exchange. You find your question and Brian Greene immediately gives you a 1-minute video answer. For example, you click at a question about "string theory" and Brian is already answering a question about "string theory". It may be a wrong question so you may choose another question about "string theory" in the list that already appeared beneath the video. Click at the question and Brian immediately begins to answer this question, too.
There are already hundreds of questions-and-answers to special relativity, quantum mechanics, cosmology, string theory, unification, big ideas, dark energy, basic physics, mathematics, multiverse, anthropic principle, parallel universes, Higgs particle, time, supersymmetry, general relativity, and perhaps other themes. You may also see the latest videos and featured videos.
Then there are short courses that should take 2-3 weeks. No homework, no work, no prerequisites, no expectation of mathematical skills, and no tuition. One just basically starts by being a lazy ignorant imbecile and Brian Greene pours the knowledge into his or her brain directly using some multimedia channels and for free – if I understand the modern technology well enough. ;-)
You must register for these courses. They include one on special relativity; general relativity; and foundations of quantum mechanics (with some non-standard titles optimized to make it sound popular).
At the bottom,, there are also links to longer, 8-10-week university courses in these three subjects. Equations should probably be incorporated there. So far, only the two (short and university) courses on special relativity are available for registration.
See several reactions to Brian's modern project in the mainstream media. Here is an example of a video from the bulk of a course which was mentioned in the Time Magazine a week ago.
What is relative about the speed? Brian Greene stands in front of a regular blackboard but has a special chalk. When it touches it the blackboard, the chalk automatically creates a red car moving on a warship (which innocent and peaceful Brian calls "a boat"). In this way, Brian may easily explain to you that to specify a speed, you need the reference frame.
Most people need the reference frame to learn anything else about physics as well but that's another issue. ;-)
I can't guarantee that the project will be a megasuccess but I do think that such new approaches to learning and teaching should spread. Many people are attending colleges because of the diplomas, however. I feel that for similar online universities to really supersede the stony ones, a system of grading, exams, and recognized degrees will have to be incorporated to the online universities. Of course, this is probably not an issue for cool popular lectures at this sort which – unless I misunderstand something – don't force you to develop the same expertise that is expected in stony colleges and grad schools. But maybe even at this popular level, some degrees could be useful.
Also, I am afraid that in the current form, the online university is even less "interactive" than the stony universities. I am talking about the feedback from real people. For the Internet to show its muscles, I think that a good online university should be more interactive and offering more feedback than the stony universities.
