It’s not all bad — remote work policy is now a major topic. You’d be laughed out of any number of job interviews for asking about remote work policy, whereas now it’s a completely fair question.

Except that this problem doesn’t specify distance between horseman, so I think it’s a bit bogus — no.need to resolve an individual person to be able to tell that they’re there. And for hair color, if you make assumptions about the clothes being worn, you could perhaps infer color of hair, even if the hair isn’t resolvable (a person being a “single pixel” would have a different hue depending).
- Comment on Make gravity your bitch 1 week ago:
Dipoles are, effectively, not — so if you have a charged bit and another opposite charged bit, while an inverse relationship might exist between either one, the net effect is that it drops off much faster.
The thing with gravity is it tends to go one way, unlike, say, charge.

Why the HUGE, irreconcilable disparity between your front page and the opinion section?
This is always how it goes, as it should. Horrible opinions shouldn’t affect the reporting; and horrible reporting shouldn’t affect the opinions. Different publication, but newsliteracy.wsj.com/news-opinion/
It’s best IMHO to think of them as two completely separate entities.

I was writing up my problem set answers once, and it involved the (complex analysis) residue. I wasn’t sure if there was a shortcut (as opposed to

This is obvious though — currently, you might test a drug on mice, then on primates, and finally on humans (as an example). It would be faster to skip the early bits and go straight to human testing.
…but that is very, very, very wrong. Science of course doesn’t care about right and wrong, nor does it care if you “believe” in it, which is the beautiful thing about science — so a scientifically sound experiment is a scientifically sound experiment regardless of ethical considerations. (Which does not mean we should be doing it of course!)
Now, taking a step back, maybe you’re right that, in the long run, throwing ethics out the window would actually slow things down, as it would (rightfully) cause backlash. But that’s getting into a whole “sociology of science” discussion.
- Comment on see the joke is that someone else does the work 4 weeks ago:
This is all based, most likely, on Griffiths’ textbook. Quoting here from this post reddit.com/…/magnetic_fields_do_no_work_but_magne… :
The statement “magnetic fields do no work” is incorrect. Griffiths has mislead a generation of physics students on this. A correct version of the statement is that “magnetic fields do no work on objects with no magnetic moments” which is rather trivial. One could also correctly make the same statement about electric fields. However, electric monopoles are very common, so a situation in which there are no electric moments never occurs in normal circumstances.

…and so did Linus Torvalds* — he’s certainly not the embodiment of capitalism. But I absolutely have a huge amount of respect for Torvalds, even if I don’t approve of his way of his interpersonal/professional style.

*He’s supposedly taken steps in the right direction here and has made improvements.
- Comment on Owing your home today is nearly impossible, but even if you did the ever increasing property taxes will bury you 5 weeks ago:
Yeah, without being a policy junkie I think a reasonable step would be to have Prop 13 only happy to primary residence — investment real estate would be subject to a “wealth tax,” but folks wouldn’t get priced out of their primary home due to gentrification.
- Comment on Owing your home today is nearly impossible, but even if you did the ever increasing property taxes will bury you 5 weeks ago:
Right, that’s a huge downside for sure.
Property tax is on the one hand a wealth tax, which sounds like a great idea; but on the other hand, it’s a wealth tax that disproportionately affects people with the bulk of their assets tied up in real estate — which often means middle class homeowners.
So while you can certainly look at prop 13 as “good” in that folks don’t get priced out of their existing homes, it of course gets used to the advantage of rent seekers, etc.
It’s…complicated.

California disagrees: …wikipedia.org/…/1978_California_Proposition_13
Property tax is assessed when there’s a sale, and otherwise changes very slowly. It’s a controversial measure.

They were thinking of making a Minority Report adaptation (with Arnold, not Cruise) as the sequel to Total Recall, with the mutant Martians as the precogs. Could have been a fun one!

If it’s a campus bus it’s almost certainly free, and probably timed to class schedules. If you only have 10m or so between classes it makes sense.
- Comment on I have an entire cabinet currently storing empty jars... 1 month ago:
Some bulk food stores let you bring your own. You put a sticker on them with the bulk item # and also the dry weight, so it’s a little more work, but then you can put your jars to use!

You can ride your bike on many highways in the USA at least. Generally you cannot on the freeway, but there are some exceptions — in California there are requirements about bike accessibility which means that certain segments of a freeway may be bike accessible.
If you live far from a store then groceries are a problem unless you use a trailer, but if you live in a city it’s totally reasonable to use a bike (or walk) for your weekly groceries.
And you can get a new Trek FX for under $600, and that’s just from a quick search. Yes of you want Ultegra or better and a carbon frame, the sky is the limit.

- Comment on Sadge 2 months ago:
Sounds like it was a 2 petawatt pulsed lase, with picosecond pulses, so 2kJ/pulse. Staggering amount of power for a pulsed laser!
Note that it’s not CW, so the average power will be much, much, much less than the pulsed power. Too lazy to find the rep rate to see average power.

- Comment on Boss Mode 2 months ago:
No, that’s not really a useful way of modeling it for the case of light traveling through a linear medium.
The absorption/re-emission model implicitly localizes the photons, which is problematic — think about it in an uncertainty principle (or diffraction limit) picture: it implies that the momentum is highly uncertain, which means that the light would get absorbed but re-emitted in every direction, which doesn’t happen. So instead you can make arguments about it being a delocalized photon and being absorbed and re-emitted coherently across the material, but this isn’t really the same thing as the “ping pong balls stopping and starting again” model.
Another problem is to ask why the light doesn’t change color in a (linear) medium — because if it’s getting absorbed and re-emitted, and is not hitting a nice absorption line, why wouldn’t it change energy by exchanging with the environment/other degrees of freedom? (The answer is it does do this — it’s called Raman scattering, but that is generally a very weak effect.)
The absorption/emission picture does work for things like fluorescence. But Maxwell’s equations, the Schrödinger equation, QED — these are wave equations.

In all seriousness though, I thought it had some aspects of good, which was odd given that it’s satirical commentary on fascism. For instance, gender didn’t really matter and women were promoted, and while the shower scene was meant to show how fascism castrates the masses (or something like that, iirc), I thought it was a relatively wholesome scene, all things considered.
