Maybe he "just" got it wrong. Maybe they're typos, and the manuscript was correct. Or...

Maybe Pemulis gave Hal an obviously wrong derivative, and when uncorrected, drove Pemulis to abruptly end the tutoring. Maybe Pemulis said it right but Hal heard it wrong. Or...

Maybe it's "just" another sign they're in an alternate universe where even the math is different. That's pretty much how I feel about it

> Again, Mike Pemulis is lecturing Hal, but this time he is helping Hal prepare for the college board exams. Pemulis states that for the function x^n, the derivative is nx + x^(n-1). In fact, the correct expression is nx^(n-1). This, too, may be a typographical error. Another possibility is that Pemulis is simply bad at math :D

Reading the DFW biography, Every Love Story Is a Ghost Story, it said that there were hundreds of cases where the editor claimed something was a typographical error, and DFW insisted that actually it was precisely how he meant it to be. They went back and forth for months, with the publisher eventually charging DFW a fee for all the extra labor involved.

So... we can't know for sure, but there's a strong case that any particular little weird error, DFW intended it to be this way. Especially for a "basic calculus" issue like this, for someone who wrote a whole book on the mathematical history of infinity. (Which arguably has its own errors, but those tend to fall more in the category of simplifications for the lay reader, IMO.)

I haven’t read IJ in a while, but I don’t think I agree with the first one. Unless he specifically said that each player has an equal chance of winning, I would not assume that to be the case.

Interesting! But then it seems like he would have said it a bit differently, that the odds of that particular tournament with those specific players ending in a tie were much lower.

I look forward to the day another book makes me feel like IJ - even with the mathematical flaws :)

Agreed. It was really a revelation to me. Looking back now, it's clear that I started reading it as a status seeking thing. I thought my intellectual friends (and especially girlfriends) would think it was cool that I actually read the whole thing (which nobody else in our circle had actually managed yet). But then it turned out to really affect me deeply.

I read it again about a decade later after all those games were over for me, just for myself, and loved it even more that time.

For some people, it just really does hit a nerve!

DFW also wrote Everything and More: A Compact History of Infinity -- an uncritical review of Cantor's work, which was absolutely loaded with errors.

Rudy Rucker wrote a scathing review here: https://www.rudyrucker.com/oldhomepage/wallace_review.pdf

I actually read Everything and More and it's probably even worse than that. Though I'll admit that I'm a little bit biased; I'm a sort of Aristotelian Realist or even a Finitist when it comes to mathematics, and I view Cantor's hierarchy of infinities as... well... schizo at best.

Personally I don't agree with that review at all, and I loved Everything and More. I'm even somewhat of a "finitist" myself mathematically, but I think you can just view the whole hierarchy of infinities as a finite mode of description, and get utility from it without worrying about the "reality" of the whole thing. But that's a bit of an aside.

The review-writer clearly hates the book before he even gets to the mathematics. The whole book is striking a middle ground between expressing every step of mathematical rigor, and describing in a more literary way how to feel about these concepts. All of these "errors" are just the author passing over a point in less detail than you would want from a text on set theory. I thought it was great, and for anyone who enjoys both set theory and Infinite Jest, I would strongly recommend the book.

I understand that some people don't like it, but it should be viewed as "controversial" rather than "everyone agrees that it's riddled with errors".
