About Steuard

I'm a physics professor at a small liberal arts college in central Michigan. I got my Ph.D. in string theory from the University of Chicago, and I hung out with a whole lot of computer geeks as an undergraduate at Harvey Mudd.

    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 limi…

    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 foun…

    [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 co…

    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 …

    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 …

    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 mai…

    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…

    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 Mi…

    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 qualitat…

    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…

    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 p…

    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 …

    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 t…

    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. (…

    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 in…

    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 f…

    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 antibioti…

    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 even…

    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 …

    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 im…

    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 …

    Just fetch it via http rather than https. Works fine.
