Sounds like one use-case of for same-sex couples to have biological children together. Which is pretty neat IMHO!

Not to say that the more macabre use cases don’t exist, of course.

…could pave the way for same-sex couples to have biological children together.

As usual, it sounds like the technology could be used for genuinely good things.

It could be used for horrible things too, yes, but that’s often how it goes.

In undergrad I took a class on sleep, and it really stuck with me. I previously had some FOMO-esque aversion to going to bed early, but after that class if I was done with the day and I was tired, I just went to sleep.

It’s been a good mentality for us now that we have a small kid, too. No shame in going to bed at 8…

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.

I kinda assumed any Mars mission would include some simple centrifugal pod. Seems like even if it’s just for sleeping it would be useful.

Dispersion and nonlinearities would like to have a word ;)

I’d like to know more.

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.

IIRC chvt is a privileged command, which makes sense (if an unprivileged user could execute this command they could effectively brick the computer for a local user).

That said, my understanding is that modern DE’s are given a lot of access, so presumably chvt is allowed (and in this case, is required because as others mentioned, password is required). So the only other option is to fail unlocked, which is all kinds of Bad.

While neat, this is not self-sustaining — it’s taking more energy to power it than you’re getting out of it. (You can build a fusion device on your garage if you’re so inclined, though obviously this is much neater than that!)

One viewpoint is that we’ll never get clean energy from these devices, not because they won’t work, but because you get a lot of neutrons out of these devices. And what do we do with neutrons? We either bash them into lead and heat stuff up (boring and not a lot of energy), or we use them to breed fissile material, which is a lot more energetically favorable. So basically, the economically sound thing to do is to use your fusion reactor to power your relatively conventional fission reactor. Which is still way better than fossil fuels IMHO, so that’s something.

If you exclude blocked instances, you’re a lot higher than #5…

Wouldn’t 25 year olds still be in school for their doctorates though?

Yes, I think that’s the point — they skew the numbers upwards.

“Chain migration” is how many people — myself included — get jobs.

I went to a very good school, and while I like to think the quality of education is what makes a school “good,” let’s be honest — the value is largely in your connections. Friend lands a good job, recommends you when there’s an opening, and bam, you’re already at the top of the pile of the CVs (better yet, they’re the hiring manager).

Friends from school — peers and mentors alike — are a great place to start, if you can. Ask to grab a coffee and chat about their career, and be clear that you’re in the market. Most people are happy to chat (at the very least, it’s flattering).

It’s the way the world works…

I particularly like the truck/engine correction.

One thing to keep in mind — the US is huge, both geographically and culturally. Flying from Los Angeles to Boston is further than London to Baghdad.

And likewise, the cultural “distance” between, say, New England or the Pacific Northwest and the deep south is extreme.

Of course there are things that affect (nearly) all Americans, but some context is important.

But this applies to the UK, Ireland, France, Belgium, Italy, Spain, Portugal, and…well…much of the world, if these data are to be trusted.

Baking is chemistry, cooking is jazz.

I’m curious how the battery percentage went up

Physicists hate this one weird trick…
