I don’t personally support the "I rather see academic books for free on the web" attitude, nonetheless my site is an iteration of this idea (math only). Take a look: http://inperc.com/wiki/index.php?title=Category:Courses

This tool is for teachers not students. Then the real question is, how easy is it to create a page like that?

>>...uniform convergence does not imply convergence in length or area... Under uniform convergence, the limit of the integrals is equal to the integral of the limit. So, this works fine for areas, or are you talking about something

by pixcavator 16y ago
Right. This way, you aren’t approximating the circle. And if you were, the area would converge to the right number. Areas are good this way, unlike lengths which is what the post is about.

Just because the conclusion is wrong it does not mean that there is no point here. What’s described is exactly what one has to deal with in digital image analysis. Here is a write-up and a link to a paper: http://inperc.com/wiki/index.php?

One party (the government) was paying another party (the captain) for their services and then they figured out the best way to do it to get what they wanted. This is not an example of governmental regulation.

I see your point now.

The popularity is surprising; the success is still to be proven (how?). But you are right, its popularity can’t be ignored.

You can check out my lectures here http://inperc.com/wiki/index.php?title=Category:Courses (math only). These are written lectures but they start at about the same place as Khan's (in a real classroom though). Hundreds of illustrations bu

According to my computations, the total amount of content isn’t that large. It’s about 36 credit hours total and I am being generous here.

I use Tablet PD with Windows Journal. In addition to what you say, other advantages over chalk are the brightness, the colors, and the ability to instantly post the lecture online. Later I transcribe the lectures into text and just copy the

Good point. I wish the printable version would automatically create a pdf.
115.
by pixcavator 17y ago
Well, the site runs on MediaWiki, so you can save the printable version of each article. Even if you print the whole thing, the end result wouldn't be that much different from a bunch of video files for each 15-min lecture.

I like the style and I appreciate the idea. In fact, I’ve been working on something in the same direction. So, here are a couple of things that I prefer to do differently. First, these are video lectures but without actual students presen

I'd suggest trying to use computer vision, exclusively. It seems to me that removing the person (and the display) and not recording images would help dealing with the legal and moral problems.

The shape of the graph should be exactly the same only shifted up or down. That's the good news. The bad news is that this is only true for a single station. The shape of the curve for the global average could be seriously affected by the f

The only way to succeed in grad school is to be single-mindedly focused on mathematics. Not on being a "generalist", not about "cliques", tenure, etc. This "meta-math" reasoning is a bad substitute for doing actual work. Clearly, the guy is
