The Lectures may occasionally mix in Imperial units, but the vast majority of the calculations use SI.

I'll look into it, but unfortunately this isn't up to me. Convincing the publisher to let us put up an online version was hard enough.

That's worth thinking about. One issue is that it's hard to tell how more more money is needed to finish it. Alas, custom software is rife with uncertainty. (Practically speaking, this means that, e.g., custom hack #37, needed to

As far as I know, the Feynman Lectures have always used SI units.

I know how you feel. I "miss" Feynman, and it's weird to miss someone you never met. (N.B. Gates wasn't involved in this project.)

Unfortunately, there's no general mapping from LaTeX to HTML, so for any realistic pre-written source you have to write many custom modifications to complete the conversion. This is a time-consuming and error-prone process, involving a

The LaTeX source of the Lectures is long and heavily formatted, so the conversion to HTML involved writing a large amount of custom software, including lots of tests to catch regressions. In other words, this was a speculative software pr

I was the project lead on this, which involved converting the Feynman Lectures from LaTeX to HTML. I'd be happy to answer any questions. Update : Most of the questions center on cost. I've answered in more detail below, but the

The OP took the elements of the original announcement—the pretentiousness, the naïve pomposity, the buddy-buddy informality—and turned them up to eleven. The result is an effective send-up of a post that richly deserved to be mocked.

The headline is horrible—it's kind of like saying "Scientist's Theories Led to Atomic Bomb" for an Einstein obit—but Ronald Coase was one of the most creative economists of the 20th century and deserves to be widely know

This article is based on a dubious premise, namely, that public speaking is harder for introverts than for extroverts. Introverts are taxed by smalltalk and the like, but they often have no trouble getting up in front of hundreds of people

So, we have "light shed" on the current "debacle" and neither system gets built. That's a win? Yes, preventing a debacle is a win.

You're right, of course. I'm not claiming that Yelp does extort, only that these allegations are the source of their imperfect reputation.
