I don’t know, but it’s effect is definitely not niche. It’s how you get GPS.

Would you agree that atomic clock for super precise timekeeping falls int the same cathegory?

Well, that sounds completely reasonable. I’m aware of this difference, but maybe I misunderstood what I read. Or misremembered, it’s been a while.

My quick search shows numbers much closer to yours than mine. I remember mine because I was surprised it was so small. I thought I read it somewhere reasonably believable (but don’t remember where), but maybe it was some estimate not generally accepted. Thanks for correcting me.

I think the current very rough estimate is around ¼ of the universe being observable.

Fun fact: smaller and smaller part of the universe is observable. As the space is expanding, it drives the furtest reaches of observable universe away faster than the light can fly. So the area, from which the light could reach us if it flew for the time since the big bang, is smaller today than it was yesterday. It really drove home for me just how big universe is.

This is actually a third one. The second was called 2I/Borisov, I think.

Seems so. In the few media I’m slightly more familiar with, the headlines are written by someone else with the aim of drawing in more readers and the authors of the articles themselves have no control over it.

The headline is horrible (haven’t read the actual article). As I undrstamd the topic, Uranus radiates more heat than previously measured, but still less than our models suggest it should.

Yes. But if you have many complaints from MANY MANY users, it may not mean anything serious, it could still mean a very small fraction have problems. Absolute number means very little without context. That’s the purpose of the previous comment. Please note how it doesn’t say anything about qualities of Windows.

I’m afraid that you don’t quite see all the complexity involved. I’m not saying I see all of it, but I can see there is more to it than you think.

What about bacteria? Not only don’t they don’t often use sexual reproduction, so they don’t need a pair of parents to produce offsprings, but they exchange plasmids and therefore DNA with little regard for species.

Plants are a complete mess of genome duplication, aneuploidy and whatnot. In these aspects, they are sort of scary to me.

Also, what about formation of a new species? Do you think there is a clean-cut time when they stop producing offspring? Also, what exactly do you mean by fertile? Where do you get a partner to test if the offspring is fertile?

These are just a few problems that came to my mind right away. I’m sure there’s loads more. I’m afraid that the notion of well organised, easy to categorise world just doesn’t match the real world. Species are more or less a continuum. Incidentally, so is life. We have no good definition fornlife either. Just use whatever definition is useful at the moment and don’t forget to specify it when necessary.

Hasn’t Beal’s list been taken down quite a while ago? I remember making a copy of it before they removed it. It was a great source, but sometimes it needed some context. I think all of Frontiers in ended up on the list for reasons, but their review process was mostly alright, for example. It was this kind of lack of clearly definedrules and explanations that let them to taking the list down. Is it back up?

Surprisingly, I just read it actually does, and quite a few. None revolutionary and eye-catching like everybody hoped, but apparently, most of us has graphene in our smartphones, for example. I don’t remember specifics, I can try to look for the article where I read it, if you want very much.

I think a quasi-particle is more like a phenomenon that can mathematically be described in a way a particle would be, rather than just a group of particles. After all, holes in semiconductors are quasiparticles caused by a lack of real particles.

Admittedly, I know very little about quasi-particles.

I use Pocketbook. It opens just about anything - epub, mobi, pdf, pdb, and many more formats. Just get a book anywhere and copy it via USB. Or send it as an email attachment to your special address and it will download automatically. You can even replace the reading app with another relatively easily, if you want.

Frankly? Yes, a bit. I wouldn’t have expected Tesla to make it that high and I would expect Google somewhere near the top. And I guess it focused only on american companies, or I would be much more surprised.

This seems like a great source, thanks a lot for posting it.

I didn’t read the original paper yet, perhaps it’s there, but it isn’t in the linked article nor its source Ars Technica article. Can authors themselves upload their papers to these archives, and if so, how to do it correctly to make it findable both by DOI and other means? Does anyone know?

I see. You can open just about anything, something like 18 formats, it’s on their website. I prefer epub, but it can open Kindle’s mobi etc. That’s why I bought it, I got a large library of pdbs.

I have Touch HD 3, I had some Touch Lux before. I had it for a while, don’t know their newest models. But yes, not only would I buy it again, I already did, just bought a newer version. Unless I was looking for something for hand note taking, I wouldn’t change. What I dislike is that when you break the screen, it’s expensive to replace, so I just bought a new one instead. Nothing you wouldn’t be used to from phones. And I’d very much like to have an option to disable the touch layer of the screen by long press of one of the physical buttons, but it’s a minor issue. What I like is the tunable intensity and colour temperature of the light and I’m quite happy with everything else. You can upload books by sending them as an attachment to a special email. If you don’t like the interface for reading the books, you can even quite easily replace it with Cool reader. I tried it before, but I didn’t do it in the newest one. You can use dictionaries, some are preinstalled, or use notes and highlights, but I don’t have experience with that.

I agree with the other reply that pdfs are terrible for e-readers. That being said, Pocketbooks can open them (which is not that common) and it is possible to read them, although it isn’t so comfortable, especially for A4 pdfs. It can also open wide range of other formats and I’m quite happy with it in general. You can connect it to a computer and simply copy your books there, among other means of getting books there. But I have to say I have no first hand experience with competition.
