Cooling magnets is important when those magnets are superconducting electromagnets. An electromagnet produces a magnetic field by passing electricity through coils of wire. If you want a powerful field you need a lot of electricity, and to do this efficiently you want the coils of wire to have low electrical resistance.

The magnets on the ITER use huge amounts of electricity, enough to just melt normal wires into a puddle. Instead they are made out of superconducting materials which have basically zero electric resistance. They need this in order to work, but the only materials we know of that can be superconducting are only that way when very cold. Keeping the magnets cold then is crucial to them working at all.

Anyone who works closely enough with computers to have an opinion on this understands that a one GB hard drive actually provides less storage space than one (proper) GB. I'm with ZylonBane. They should have made 1000 bytes a kibibyte (therefore releasing most of us from having to use it) and left kilobyte alone as the proper term. If anything I will use kB or KB but not KiB. That's just silly.

Omg yes, i forgor 💀

They take dairy calves away from the mothers and bottle-feed them (or sell them for veal). The milking makes her body think the calf is nursing, a lot, and so she keeps producing milk steadily, usually for about a year. Then she has to have another calf to keep the milk supply going.

If you have a small homestead and don't need a lot of milk from your cow, you can let her keep her calf and still milk her, and that will be enough milk for most homesteaders. But it's not profitable for large dairies.

If you saw the calves with their mothers, those are likely beef calves. They used to remove the calves at a certain age to force weaning, so the mother could back get in shape for her next pregnancy, but trial and error showed that caused more losses than it prevented so most beef calves stay in the pasture with their mother until they're old enough to go to a feedlot.

The infections could cause all sorts of problems.

Your body's response will be fairly similar in many cases: "intruder alert, expel everything!" is a common one and covers sneezing, coughing, vomiting, and diarrhea, depending where the infection is. Likewise, your body sends a squad of white blood cells in full riot gear to the site of any infection - which then causes swelling as they flood the area.

No they don't. Milk cows have to regularly calve to continue giving milk.

And the thing is, those calves, if they aren't female and can be used for milk cows, will eventually be slaughtered for meat. Which is why many vegans consider cow milk to be as bad as eating cow meat itself.

Strictly speaking, it's not the virus causing the fever or the sniffles and sneezing. Your body does these in response to the viral or bacterial threat. Raise body temperature in an effort to literally cook the invader to death. Sneeze to expel the invader, etc.

We only have so many symptoms to go around because our bodies can only respond in so many ways.

Veterinary technician here. Short answer: No they do not. Long answer. When a cow gets a calf she produces milk. The more they milk her the longer she sill produce milk as her body thinks its feeding a calf. The production of milk slowly reduces over time and farms need to calculate this in order to be profitable. Once it is not profitable anymore they stop and wait until she recovers and is ready for another calf.

To me your analogy sounds like changes to the world (=story) are saved by changing the seed (=title) to a seed which generates the changed world. But there is no seed that will generate a world with my oak plank house in it. Maybe I just got your analogy wrong, I believe we both mean a similar thing.

All of the above are the body using various methods to expel or combat the virus. They're similar for many viruses because those are the tools our body has to fight viral infections (though obviously it's not all the tools)

>because most mammals are colourblind

this one has always been weird to me, apes aren't the only mammal that spent a lot of its time finding red berries in a green background, why were we the only ones lucky enough to get trichromatic vision?

Plus the extra efficiency loss of mechanical-electric-mechanical conversion.

that's close to correct, but it's not multiples of 8. it's powers of 2.

MVP!

Prepare for disappointment when getting a harddrive.

Yup, more or less.

I have multiple pairs of active hearing protection for shooting and for work. These are really common and my personal favorite. The only downside I have found is you lose the ability to tell direction of noise very well. It turns "Front left and above me" into just "my left" or "my right" Ironically, even with this downside, I can still hear better with them on vs without them.

They are a must have item for new shooters as they can still hear when giving directions.

Noise cancelling headphones work by playing the exact opposite sound wave, to cancel it out to nothing. This means that they can only cancel sounds that are as loud as the loudest sound they can play, anything louder they won't be able to cancel out fully. And because they don't want to get sued / fined for playing noise at ear-damaging levels, they cannot cancel out noises that are ear-damagingly loud. They can help a bit, because they do cover your ears and hence dull the sound a little, but they cannot substitute proper ear protection.

On the contrast that’s exactly what ANC does. It produced sound waves that destructively interfere with the existing sound waves so that they are effectively destroyed or reduced in power by the time they reach your eardrum. Additionally ANC headphones encourage the user to listen to their music at lower volumes as they don’t need to drown out exterior noise, also helping reduce ear damage

If I got your analogy than that is not true, not every possible world has an associated seed, there are far more possible worlds than there are possible seeds.

Thank you so much, this is extremely helpful.
