Given the story is about a particular instrument, it was kind of annoying that you can only really hear it by itself for a brief segment. If I was listening to the music just to listen to music, then yeah, the extreme bass flute wouldn&#x2

She plays some notes at about 1:10 without the high-pitched flute backing track. Kind of surprised it has a lot of harmonics. Flutes generally produce something that's at least close to a pure sine wave, but apparently not this one.

In theory I suppose you could improve the braking ability quite a bit by having a flywheel spinning about an axis perpendicular to the axis the main wheel rotates at, to act a gyroscope and prevent the "gerbiling" problem the arti

If this is a thing people can actually build, government would have a hard time stopping them, or even knowing that people were working it if they decided to keep a low profile. It might not even require specialized hardware, or a particul

The point of that video seems to be to dox the person who filmed the other video, probably with the intention of making his life a lot harder and less safe. That's really creepy.

Is it just that infrared light doesn't focus as easily as visible light unless you scale up the size of the telescope accordingly? (For instance, at some point light stops behaving like light and starts behaving like radio waves.)

According to that video, almost all of them have expired but there's one more that might be important that expires on April 27, 2022.

I don't think so, but I don't have specifics. There's some sources that a typical Tesla battery pack might have about 10-12 or so kg of lithium. LFP is a different chemistry, so it might have a different proportion of lithi

by elihu 5y ago
If it's an LFP battery, I think those are pretty easy to recycle but the materials weren't worth much to begin with. It's mostly just lithium, plastic, aluminum, fertilizer, iron, probably graphite, and copper.

I think patent licensing is a bit of a concern. As I understand it, a lot of the big battery manufacturers in China have an agreement that the don't need to pay licensing fees for batteries used domestically, but if a major car manufa

We don't need to replicate Hubble exactly; I'm just suggesting we should put up some cheaper space telescopes with smaller mirrors than James Webb, if such a thing makes sense. Maybe give them a variety of different focal ratios
979.
by elihu 5y ago
I agree with that, but still it's sometimes worthwhile to have a few dull knives around as well as backup. I mean, Hubble isn't huge; it's a 2.4 meter aperture. Building and launching something equivalent shouldn't be

Would that even be beneficial? If the problem is that there are fewer insects and therefore the birds have less food, then cats suppressing the bird population might have a positive impact on insects, which the birds eat. That might be go

Possibly. I think you can get a pretty good idea if you'd like the original series just from watching the first few episodes.

I think the movies are a lot more focused on just on the main characters, which is a bit of a shame because one of the great things about the original show was that in the later episodes it becomes increasingly more apparent that most of th

That sounds plausible. Cats can be very effective predators.

Maybe this is related to declines in insect populations? I mean, if birds eat insects and there aren't as many insects, you'd expect there to be less birds as well.

It's a different experience. POV-Ray is basically a programming language. If you want to generate geometry programmatically there's nothing quite like it. The "programming" features are primitive ("if" state
