Your link and claim about THC is totally wrong. The problem was with people adding vitamin E acetate to the liquids. This is a problem of manufacturing of liquids that doesn't seem to appear much anymore and has nothing to do with THC itself.

Avoid home made liquids like plague. And avoid vaping if you can, continuous irritation of anything in your body is always linked to bad outcome and we don't have enough data on long term use of vaping yet to rule it out in that case.

Flavors can also be extremely bad and these are even less studied and change all the time. Look at popcorn lung for example https://www.lung.org/blog/popcorn-lung-risk-ecigs

That's one compound that makes damages pretty fast for example (and was well known, so people that flavored ecig liquids with that are criminals)

There are no known negative effects from inhaling glycerin vapours. There are concerns around some flavour compounds used in e-liquids.

In grapes, mandarins and watermelons there's not much you can eat from the fruit where you're sure to not get any seeds. So getting rid of the seeds is a big improvement.

With apples, most of the fruit is never going to have a seed and you can just munch carefree until you get to the core. Same with other types of melons that have their seeds all in the middle. It's so easy to scoop them out that developing seedless varieties isn't worth it.

Developing new apple varieties is also a slow process. It takes up to 8 years for an apple tree to bear first fruit so you can find out if whatever you've created tastes any good.

There are also a variety of ways that seedless fruits are created. With grapes they manipulate the plant into making a fruit without seeds but those tend to lack the hormone needed to make the fruit grow to its normal size. Applied to apples you might get seedless apples but only of the size of apricots or so. And again, you have to wait up to 8 years to find out.

With melons they have two fields of different "parent" melons that when you put the pollen of one type on the flowers of the other the resulting fruit can't make seeds. Which is a tricky but doable for large fruits like watermelons. Doing that for a whole apple tree is much more effort (if that's the road that would need to be taken).

TLDR: It's a LOT of work for an uncertain amount of benefit.

As a French speaker the order just "made sense" to me, as it does in French.

CPU cores each run a different program.

GPU cores all run the same program at the same time, but each core operates on different data. They are much slower and more basic than a CPU core, but also much smaller (because they don't need all of the same parts) so you can have thousands of them. Because of that, you can use them to crunch a large amount of repeated calculations very quickly. This is used for mostly for the per-pixel calculations for your display, but they can be also used for other things too like AI training (or Bitcoin mining if you hate the environment.)

Historically it's because months were based on the lunar cycle (even the word "month" comes from "moon"). In lunar calendars each month is one lunar cycle, which is 29.5 days long. This results in 12 months a year + approximately 10 days (so in lunisolar calendars, sometimes a 13th month is added).

Anyway, now we use 12 months because it's convenient. 12 easily divide by 2, 3, 4 and 6, unlike 13 which is prime.

I think the technical term is countable vs uncountable.

Same way we say "I drank so much (uncountable) water" but "I drank so many (countable) cups/bottles of water".

Or "I lift less (uncountable) weight. I lift fewer (countable) weights"

The short answer is that copyright holders want to make money off of the books they own the rights to, and because of that they sell the license to their digital books to libraries under strict terms.

The longer answer involves explanation that not only are libraries limited in the amount of simultaneous copies that can be checked out, but they are also limited in the number of times those copies can be checked out before the library has to renew the license.

The whole issue is very complicated, trying to balance the rights of authors and publishers, with the public interest, and many misconceptions about copyright and economics on all sides.

yes

A fish might eat another fish, then get caught by a fishing boat. But negligible. More nutrients are constantly being created at the surface (eg plankton) than any number of whalefalls.

Because refreshing the screen means the device has to calculate what shall be rendered and where on the screen, and then actually render it.

So imagine repeating this job 100+ times every second, it will require a lot of energy compared to if it only refreshed say 30 times a second

Or you can just imagine atoms in a valley with iron at the bottom and the fusable nuclei on one side and fissable nuclei on the other side. Supernovae are like skateboards where you can get from the fusable side the the fissable side with a bit of momentum, but once you're at the bottom of the valley (iron) and have no energy source or "momentum", there's no getting back up either side.

Lets explain a few things

First whats an Hz, a Hz is a clock movement, its the rythem to which a process advances. its a clock tick which fixes the rate in which it works.

Hz is mesured at X/second usually, X being the number, so 60Hz is something that happens 60 times a second, your 5ghz processor has a work rate of 5,000,000,000 clock "ticks" per second.

to display video, a display usually works by using still frames at a very fast rate, 24fps for europe and 30fps in the US, mainly becuase the electricity which carries a AC current which provides a 50 or 60hz clock signal, this is a legacy component (a left over component) from when TV signals used the electricity frequency as a clock signal.

the thing is that with digital video and every device having its own clock signal (usually a quartz occilator on the board) theres no need for this now, and especially with gaming class video cards, they exceed the normal output of 24 or 30fps or even 60fps.

So you can use a higher refresh for a more immersive expiriance,

The problem is that the more work done by the GPU, the more power it consumes, and the display has to redraw the whle screan, meaning reseting all the pixels and recoloring them for each frame, and if th display consumes 1watt per redraw, at 30fps it will consume half of what it consumes at 60fps. (lighting not included, thats a constant power cost)

Theres also Interleved (thats why you see P or i next to resolutions) P is progressive scan that draws the whole image, and interleved draws only half the screen in every other line, but since its so fast you dont notice.

and as a final note, theres Vsync.
V-sync, aka vertical sync is a technology which fixes the video cards frames per second to a fixed refresh on the monitor, so if the monitor has a 60hz refresh, it will not allow the video card to exceed 60hz. now more advance technologies like g-sync and freesync adapt the videocard output to the maximum refresh of the monitor, but this is more to avoid screen tearing, which is when the Frames per second the video card is outputting is not divisiable by the refresh of the monitor and you start getting half rendered screens.

Not really 13*28 = 364. We'd be 1 short of a year plus an additional day every 4 years.

13 is also prime - so things like half year, quarter year etc falls in the middle of months. If we agreed, it would just take a bit of getting used to.

There isn't going to be a very nice division - no matter how.

They were still around in some older planes in the 00s.

Some other good answers already, but this is ELI5, so let me anthropomorphise everything for you. Lets swap the concept of energy with the concept of money.

Hydrogen is a very rich atom. So, it has the abillity to do as it pleases. It can afford to fuse with another hydrogen (actually more than one hydrogen atom involved here...) to make helium. The money the hydrogen atoms pay is released into the surroundings, and so the helium atom now cannot afford to become hydrogen again. Helium can still afford to fuse into carbon and oxygen, which can afford to fuse into neon, then silicon, and then iron.

Iron is now the poorest element. It cannot afford the cost to return to silicom, and it cannot afford to fuse to heavier elements. On its own, it's stuck. If iron wanted to change, it is completely reliant on the its environment to provide money for it. Not even the core of a star can afford the cost, but a collapsing star absolutely can, which is how we believe heavier elements are made.

Finally, you may ask "just because helium can afford to fuse, why does it?". The answer is because helium never wants anything, it has no will. If it's possible, then helium has a non-zero probabillity of doing it. Helium cannot spontaneously become hydrogen, but it can fuse to heavier elements. Given enough time, it'll happen.

Hope that helps!

Because it doesn't have to calculate what's on the screen as often lowering the power consumption of the cpu/apu

I think it depends. I received a ton of e-mail sounds find to me, but I'm going to write 3 e-mail is definitely wrong. Something about whether you're using it as a discrete or bulk noun I guess.

Pineapple has a chemical in it that breaks down protein. Your mouth is made of meat and protein, so it tries to break down your mouth, causing the tingle.

Authors and publishers are trying to make money and have the head start on schools and public libraries.

Education systems are typically geographically fragmented including schools, libraries, museums etc. This reduces the scope for scale discounts, but publishers do have deals including physical book discounts and ebook license discounts for bulk usage. After all a library system is just another customer and they are still trying to make money.

Some countries do have a National Library system where certain libraries can demand a few copies of any published books for free. This is the exception, not the rule, though.
