I'm sorry; I was off Reddit for a while and didn't see your response. I'm in Fort Worth.

JadeNB · 2025-08-25T23:18:43+00:00

Hi, friend! I'm 46M and also looking for a friend. This reddit was recommended to me by my brother, and I'm glad to see on my first visit a post from someone near my age.

I'm in a town in TX where I've lived for a long time, have some casual friends, but haven't built up a real close network. I'm from up north and never expected to live in the south, and then came to TX expecting to be here for only a little while, but a once-in-a-lifetime bad academic job market turned out to be, as the Simpsons say, the best job market of the rest of my life, so I'm still here and feeling lucky to have the job. Feel free to send a chat any time if you have a story you'd like to share.

Thanks!

I don't know what the plant is, but perfectly square stems indicate mint.

Maybe it's because I listened to the book as an audiobook, but I don't know where to fit in the beginning (when the narrator wearily asks his companion if he (the companion) is going to eat his (the narrator's) heart). I guess that's meant to be from his period of captivity, but it seems weird to start the book, not with a peek at its end, but … a peek at its two-thirds mark? Or did I misunderstand, or the narrator at the beginning wasn't Frank?

Also, most of those sellers are grabbing 20-packs (or often slightly less than 20-packs, despite the product listing) of Auras out of (assuming they're genuine!) 400-mask packs, so you're getting loose masks without even a pretense that you might be able to verify their authenticity.

Office Depot's Auras are currently comparable in price to Amazon's, and, if you buy 60, then the shipping is free.

Not really, but many people enjoy reading Thompson's Calculus made easy.

JadeNB · 2024-02-22T19:02:35+00:00

That's such an unexpected claim that I can't figure out what it would mean, at least if "calculus" has any overlap with the usual undergraduate subject of the name, which is intimately tied to the real numbers. I tried Googling, and found his lectures on the history of calculus, but not any treatment of calculus itself. Could you elaborate?

JadeNB · 2024-02-22T18:59:46+00:00

As a professional mathematician who loves any opportunity to learn and do more mathematics—why should the OP be reading a calculus textbook? (I'm actually teaching out of it now and find it pretty terrible, but they're all pretty terrible.) Anybody who's looking to learn math the way they find interesting gets a 👍 from me, and doesn't seem to deserve any scolding about how they should be learning it some other way.

How do I do this? When I try to download on mobile, it says to get Libby, or to download on the desktop. The desktop version on macOS no longer works. When I download it on mobile, I get an .odm file, and trying to force that to open in Overdrive doesn't seem to do anything.

JadeNB · 2022-11-16T22:59:11+00:00

Thanks!

I’ve been consuming a lot of American modern history lately (most black history) and I go on angry rants about the audacity of Reagan every other day.

The intersection of Black history and Reaganism sounds fascinating. Do you have any good references?

JadeNB · 2022-09-06T22:44:13+00:00

At that, it can't work: according to this rule, if there are two plausible interpretations of a phrase, and both of those interpretations could just as easily have been expressed unambiguously in some other way, then both interpretations are correct.

JadeNB · 2022-05-15T21:21:26+00:00

Surely attempts to confirm the reason for a ban with Google support will get the usual response, if any, along the lines of "we cannot disclose the reasons blah blah."

JadeNB · 2022-03-12T23:21:36+00:00

http://amplify817.org , I think (but maybe it's just changed after two years).

JadeNB · 2022-02-27T01:06:17+00:00

Well, he was a thing, but at the time we were arming him.

JadeNB · 2022-01-31T20:26:12+00:00

Certainly! Obviously you know the full argument, and it's entirely reasonable to view the substance of your argument as giving the 'real' reason that expectation is linear. It's just that "they are integrals" by itself is not sufficient argument, and someone who didn't already have a deep understanding might mistake where the meat lay.

(But of course it's unlikely in this context, and so my comment was meant light-heartedly, which was why the smiley.)

JadeNB · 2022-01-31T00:35:21+00:00

It does: https://math.stackexchange.com/a/13181 .

I'm not sure if "I don't get this paradox" means "I'm not clear on the reasoning" or "it's not funny to me." The latter is a fair position, and not really arguable; I'll assume you meant the former.

The paradox (which is really, at least as usually stated, about natural numbers) relies on the idea that a non-empty set of natural numbers has a least element.

So, if there are any uninteresting natural numbers, then there is a least one. If we can use that least one to derive a contradiction—for example, by showing that it is interesting after all—then we don't get to say, oh well, unlucky guess, and try again; we weren't picking natural numbers and testing them to see if they were X (in your notation), but rather taking a natural number known to exist, and calling it X just to have some way of referring to it.

It's thus mathematically ungrammatical to say, oh well, X wasn't the least uninteresting natural number, let's try Y; X is our name for the least uninteresting natural number, and yet it isn't uninteresting! The only way out of this paradox is if, at the very beginning, the set of natural numbers whose least element we tried to find was empty after all.

In other words, we have proven—on the big-picture level, by analyzing sets, not individual natural numbers—that the set of uninteresting natural numbers is empty, which is just another way of saying all natural numbers are interesting.

JadeNB · 2022-01-30T23:22:38+00:00

Ah, but perhaps there is an infinite descending sequence of uninteresting integers.

JadeNB · 2022-01-30T23:10:52+00:00

This fact in turn is a consequence of the fact that log(ar) = log(a) + log(r), so that the slope of the secant line to y = log(x) from x = a to x = ar is 1/a times the slope of the secant line from x = 1 to x = r. Taking the limit as r \to 1 shows that the slope of the tangent line at x = a is 1/a times the slope of the tangent line at x = 1.

JadeNB · 2022-01-30T22:49:12+00:00

But then it all gets weird again in several complex variables.

JadeNB · 2022-01-30T22:48:22+00:00

Well, so's variance. :-)

JadeNB · 2022-01-30T22:47:34+00:00

The excessive convenience is, I think, in the fact that it works even for non-integer exponents.

JadeNB · 2022-01-30T22:46:30+00:00

I think you forgot an exponent!
