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.

I didn’t check the calculation, but I guess it assumes perfect conversion of motion to heat. But it’s good to know that if you can get a perfectly static chicken, you can hypersonic-slap it cooked.

Do they actually work? I don’t have actual experience, but I heard that they are only used by people who might benefit from them and thus the authors are automatically suspicious to the reviewer, plus you almost always cite your previous papers in a pretty obvious way, so it’s hardly blind anyway.

Cool, thanks for the info!

How does Plantnet fare in tropics?

That didn’t sound right, my experience that depending on luck and season, somewhere between 50 and 90 % of big mushrooms I come across in a forest are poisonous or at least disgusting. I admit it’s a very wild estimate and I’m very far from knowing all the mushroom I come across, but still, that seems like a big contradiction. So I followed your link to the primary article.

I suspected that they might only count potentially lethal mushrooms, but no, it indeed seems they count even those that only make you nauseous. The problem is in the other number. The 100 000 means all funghi, it includes for example all yeasts. Most funghi don’t create mushrooms that anyone would consider picking. So the ratio you calculated below is WAY off.

I would also like to note that the number 100 seems to come from a very simple PubMed search. Basically, if nobody wrote a paper about someone being sick after eating a mushroom, they wouldn’t find it. I don’t think that would mean that many foraged mushrooms would be missed, but it is a limitation worth knowing about.

Rubroboletus satanas is definitely poisonous. On the other hand, Imleria badia is very good. Bruising blue doesn’t really say anything about edibility.

I’m not an expert, though.

Not so much Amanita phalloides as Amanita pantherina, that one looks much more similar. But I agree, if you know what you’re doing and don’t pick mushrooms with which you don’t have experience with and aren’t sure about, you’re good.

I used to pick up even Amanita rubescens, an acual (although edible and tasty) Amanita, so even more similar to poisonous ones. But I didn’t have an opportunity for quite a few years and now I wouldn’t dare, until I got an opportunity to verify with someone experienced and trustworthy.

Well, if you want to head that way, there’s Etruscan shrew. Less than 2 grams of weight and 4 cm of length.

There are also wimps. They might be dark matter.

I really like RING - really interesting new gene.

And his wife’s was Smith. They combined their names when they married.

It should be said that this is from Science Abridged Beyond the Point of Usefulness by Zach Wienersmith.

If you want to be able to write practically anything on mobile, including ≠, ≈, ‰, ℝ etc., have a look at Unexpected keyboard. No spellcheck or autocomplete, though.

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

Cosmology and astrophysics are considered classical? I would expect both quantum physics and relativity to play a major role nowadays.

For plants, PlantNet works very well for me.

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.
