I can't say what the reality looks like today, but when I was in college 25 years ago (Harvey Mudd), closed-book take-home exams were pretty common (often with a specific time limit: maybe 3/5/8 hours), and I would have been

Do you by chance have references to those conceptually cleaner bivector publications? I've spent a good bit of time looking for other people working in that space, and haven't found much other than an article by Jancewicz from 198

[Possible obscure spoiler] A friend once showed me a post on rec.games.roguelike.nethack where someone was finally begging for a hint because they'd gone deep in the dungeon and couldn't figure out anything to do next. They couldn

If you come up with a process to do that efficiently, the helium will be a lovely bonus but not remotely the most important result. :D

In principle, flagrant abuse of the pardon power is blocked by Congress's ability to impeach and remove a President who engages in such abuse. In practice, that has always been an ineffective threat against Presidents who are within da

All I have to say is that if one of my students turned in those curves as "best fits" to that data, I'd hand the paper back for a re-do. Those are garbage fits. To my eye, none of the very noisy data sets shown in the graph

How old are you? Because I promise you, that description was pretty much spot-on for most shows through most of the history of TV prior to the late 1990s. My memory is that the main exception was daytime soap operas, which did expect view

The article feels like LLM output, too. (And they don't actually credit an author in the byline.) Is there another source out there that this was based on? Can we read that instead, and skip the extra layer of interpretation/disto

I'm a physics professor who regularly teaches about special relativity in my Modern Physics course. I've made a web app for drawing spacetime diagrams (technically, two-observer Minkowski diagrams), which are one of the best ways

Ah, I see what you're getting at. My instinct here is that (exactly as you've pointed out) fields like E and B will fall off like 1/r instead of 1/r^2, but that all of the qualitative behavior will be basically the same.

I don't pretend to know what this simulation is doing, but for the record, electromagnetism works just fine in 2D. You might be thinking "but magnetic fields are intimately tied to cross products, which only work in three dimensio

I think that the previous poster's point is that historical photographs are not in-scope to be added to this project: for example, this project will never include the first known photo of a living platypus (or a living cat, as noted)

Is there a place to submit an issue with the data? The final map makes it look like a bunch of properties around the neighborhood were purchased by the University between 2004 and 2005. But I recognize one of them (5125 S. Kenwood, just sou

It's quite possible that there's a real effect here. But while I've only had time to skim parts of the paper, I don't see any indication of whether the authors have accounted for the different norms in different fields w

Sure! There are always people out there who obsess over linguistic and behavioral purity, and they tend to be very loud. I'm not certain that I've ever met one of them in person. (I've certainly met people who might say (e.g.

Accessibility has always been part of DEI. (Certainly it's been a repeated topic of conversation in my campus's Diversity and Inclusion Advisory Board.) And yes, any effort that involves spending time or money to make sure that ev

I don't know how old you are, or whether you ever really knew the web in the prior era that we're talking about. Forgive me if I'm making flawed guesses about where you're coming from. Back in the day, if I wanted the an

Reading through the report, the trouble turns out to be that "devastating disease for humans" is possibly the least of our problems. Even if we had a perfect stockpile of antibiotics that would protect humans against any possible

There were easily visible stairs in my level 1 and level 3, but on level 2 I walked around the whole map twice without finding them. Possibly I was just being oblivious, but I eventually tried moving sideways onto what I thought was a sligh

The impact on election news coverage may not be that serious. Quoting from a NYT newsroom person: "NYT Games and Cooking are BEHIND THE PICKET LINE. Please don’t play or engage with Games or Cooking content while the strike lasts! Ne

I see your point, that it's really just an overall normalization for the size rather than anything to do with the shape . I can accept that, and I'll grant them the "four non-zero parameters" claim. Though in that case,

Sadly, the constant term (the average r_0) is never specified in the paper (it seems to be something in the neighborhood of 180?): getting that right is necessary to produce the image, and I can't see any way not to consider it a fif

You want to know why a monopoly is bad, using only evidence from when it was not yet a monopoly (or not quite)? That feels to me a bit like missing the point. I think for a lot of us on the older end, we lived through the era of Microsoft I

I guess I'm not entirely clear on the background/context here. I gather that the tweet's author isn't a serious Nethack player himself, but he is trying to train a neural net to play the game, and his training system som

It's fascinating how much of this reflects societal priorities in what to reward. That's made entirely obvious by "education" being one of the low ROI degree programs: teaching effectively genuinely does require a coll

You're right: the "more distant galaxies are moving away faster" point is just Hubble's original observation of an expanding universe. It's not an argument for cosmic acceleration. (If you see people making that cla

I took two points from this part of the article. First, that the expected exchange for years was "users create content, the companies provide the platforms and show ads to pay for it". But over time, the companies have not just ad

I don't quite understand the words you're using in your "the logic is as follows" list. (What are "gaps that otherwise invalidates math and disqualifies observed measures"? Really, what are "observed measu
