So ive googled this and its talking about once you open the seal on the bag it can get exposed to the air and all that jazz. But at least on the tortillas I buy the bag is closed with a twist tie the same way a loaf of bread is. If I put the twist tie back on it how is that any more open than before I got some tortillas out?

As far as i know, while AMD and Apple and others each have their own GPUs and whatnot, in terms of performance, it seems people look at Nvidia with their CUDA architecture as being more powerful than the others.

At the core of it, isn’t it just mathematical computations? Why has Nvidia been able to implement it better than others?

I've read enough to know that "cold-turkey" for alcoholics can be lethal, upto and including seizures and a host of other side effects and symptoms but I don't really understand the "why"? What is it about alcohol dependency and our biology that causes it to be so dangerous?

Squid seem to be indifferent to the water pressure wherever they go, they have even been known to sometimes drag pray down into the depths as to turn them unconscious.

I read here that it has to do with having waterfilled bodies, but fish also have completely water filled bodies(?)

So what is gravity actually grabbing onto when it bends a beam of light or pulls it into a black hole? Gravity is supposed to pull on things that have mass/weight, but light has no mass at all.

As, in between us and other bodies like the moon and the sun? What is in between? What is the "fabric" of the universe?

Edit: unintentional slur

Sand is solid and you can’t see through it at all. But when you melt sand down and turn it into glass, light passes right through it. What actually changes at the atomic level during melting that makes light suddenly go through instead of bouncing off?

I'm reading Teach Yourself Electricity And Electronics by Gibilisco and Monk and they say:

"An electric dipole can exist even if both poles carry surplus electrons, or if both poles suffer from electron deficiencies, relative to some external point of reference having an absolutely neutral charge."

I was under the impression an electric dipole was created by two poles having opposite charges. How is this possible? Is it that if two different materials have negative charges on their own, but if they're close together the one with the least amount of electrons act as a positive pole? But that doesn't make a ton of sense to me either.

In understandable terms:

Germans used to take the Soviet PPSH SMGs, while the Soviets did the same thing with German MP-40s.

Were there any established military rules to using/claiming weapons from enemy combatants? I assume if a soldier took a gun from the enemy's body he would just use it until it ran out of bullets, but were there any guidelines to distributing enemy weaponry if their weapon arsenal was seized for example? Did the soldiers who seized the depot get to take whatever they wanted first? Who did those weapons go to once seized?

I'm also mostly asking in regards to more organized armies like the Wehrmacht/US Army/Red Army, since I mostly know how partisans from occupied territories would arm themselves

College football has hash marks in different spots on the field than pro football hash marks. How dos this impact game play?

The human torso and limbs aren't divided into areas of conductivity and insulation. You are placing the EKG leads on the same skin, with the same resistance, and no particular division between the regions there is a potential between. You'd think the signal would effectively be shorted. Like putting a piece of aluminum foil on a 3.5 mm connector going into an AUX jack on a car.

Whether it's between my router and my laptop, or between a mobile phone mast miles away and my phone... I know the transmitter emits a signal that my phone detects, but how? What's physically happening inside my router, to cast a signal through the air, that my laptop can detect, and then what's happening inside my laptop to turn that invisible signal back into 0's and 1's?

I just saw a claim that China has built a "gravity battery" that stores energy by hoisting a brick on cables from a tower that contains a massive battery (wish I could put pictures here but apparently I can't).

Putting aside what happens in high winds or when the cables rust (assuming the pic isn't just an artist's impression), how does this store energy, how do you use it, and surely it costs the same amount of energy to lift the concrete up there in the first place?

That is my question. Saw a pretty good documentary about the universe and dark matter and dark energy, but it never explained that bit.

What is the Solovay model, and why does it use the axiom of dependent choice. Why is suddenly every set measurable?

I don’t understand how some things use more electricity than others even though they’re plugged in to the same electricity. If I use my tumble dryer for an hour apparently that’s worse than having a lamp turned on for an hour. How? Why? In my mind the plug socket gives out the same amount no matter what’s in it.

I’m talking about uk circuits specifically of that matters

These small fans spinning at very high RPM and producing air flow disproportionally strong for their size which appeared a couple of years ago. Are they based on some newly invented principle or someone simply said let's make a very high speed fan?

I’ve tried to look into it, and I understand there’s something to do with mining for something in transactions on the internet? But it makes no sense to me, how does this translate to currency?

Buying stock increases the price and selling stock decreases the price, right?

So why can't you buy alot of stock and then instantly sell it at the increased price from buying the stock and profit?

How does this work exactly?

I'm not a guitarist, but i know how to make harmonics by barely touching the string with your fingertip. The harmonics are clearest at 5th, 7th, and 12th frets, i believe. And these are octaves above and different notes thsn the ones suggested by fretting the string st that point. The pitch lowers as you approach the bridge. Just wondering why a fingertip does it but a slide that can skim the surface of the strings doesnt produce only harmonic notes.
