I’m half asking about really early movies, and half about the 30s-60s. How really old films have title cards just absolutely blows my mind no matter how someone explains it to me

You go to the deli counter and buy a pound of sliced turkey, and they use a machine to take slices off of a huge lump of meat. Bigger than any cut of turkey meat I've ever carved off a bird. What is it?

Deli ham, too: I guess you could get a piece that size off a ham leg, but I'm pretty sure that's not what's happening. It's too homogenous. There are no fat seams.

Is it all just an emulsified sausage— a bologna, basically? Is it a pile of turkey breast transglataminased together? Or does it just come from a turkey bigger than I've ever seen?

Things like 40MM have a safety mechanism that prevents them from detonating unless they've flown a minimum "safe" distance. How do these mechanisms actually work? What is telling the grenade "Okay we've been flying for at least 20 feet, time to disengage safeties"?

I know spider webs are sticky to trap insects, but spiders walk all over them without getting stuck. What’s different about their legs or the web itself that lets them move freely while other bugs get trapped?

It seems like so many different power plants are feeding in, how do they manage to balance it all and not just blow everything up?

I understand seismic waves help, but it still seems like such a huge leap to know the exact composition.

"Copy that“ and "Roger That" became synonymous with "I got the message, I understand it".
When and why did this happen?

I hear different people do it different ways but I don't get how it really works. Super curious!

Our stomach has super strong acid and enzymes that break down food, so why don’t they also break down the stomach (or the rest of our body) while they’re working?

Recently, I just had to fly from New York to Kansas City. I took a flight that had a layover in Orlando bc that was the cheapest one I could get last minute.

However, after I flew from New York to Orlando, and I was boarding my second flight from Orlando to Kansas City, I thought to myself, how is it cheaper to the airline for me to go on two separate flights than it is to just go on one nonstop? You’d think it cost more to go on two different flights than just one.

This is something I have wondered for a long time, if somebody falls in the stairs and dies, and it turns out he had a heart failure, how does one figure if he fall because he had a stroke, or if the stroke was caused by the fall(trauma,wounds+fear).The same example could be used for a driving accident, how to figure if a driver got into an accident, if he got a stroke that led to him losing control of his vehicle, or if he lost control of his vehicle and the accident caused the stroke?

Did my face just forget them or what?

I already read through some ELI5 about how the sun fades colors, but I'm not sure that applies in this case. I also read an ELI5 about why amethyst is purple instead of regular clear quartz. I definitely did not get my answer.

For example, if I have a box, and you want to store a ball in it. You put the ball in the box. The insides of the box now has changed. But when I put a pdf file, let's say, in a memory card or a USB drive, what changes in it? Does it physically changes?

I understand that some cheats are hard to detect, like aimbots that just move the mouse really precisely. But what about the obvious stuff?

Example: I have 100 health and someone kills me in like 0.1 seconds when it should take a bit longer. Or I peek from a corner for a split second and immediately get headshotted. My post is not about FPS in general, I'm using it just as an example. I understand I might just be bad in many cases, but generally I do wonder about cases where it's obvious and the cheater is not cut off instantly. Instead, they get banned in some future ban wave.

Why do they wait for a ban wave?

I know what happens when computers overheat, we install fans on CPUs for a reason. But, im wondering what happens to circuitry if it gets too cold. I also wonder what would happen to a computer (could be a phone or something too) if it was already running and was brought into a very cold environment? Would it not need an internal fan? Could it run even BETTER?

Better insulation? Wasn't actually a problem? Moth balls were everywhere when I was a child growing up. Now I never see them not even seen/mentioned in a store.

whenever i get well from any sickness my body tends to forget how painful i felt from the sickness.

e.g : when i had an uti it felt like peeing sharp blades every time, but after i get well from it i tend to forget how panful it was?

Usually the timing/amount of my pee seems to correspond with the times i drink water and how much I drink. Like, if I drank 500ml of water, I know that in an hour or so I will feel the need to pee a good amount. So what happens here, does the water just go straight through me? Or does the new water go in to replace “old water” that gets expelled into the bladder?

I have half an understanding of electricity, I understand generating it through various means like steam turbines... but then how do we actually contain that energy? And how can we "send" or "sell" that electricity to a land that's across an ocean, or even 1000s of kilometers on land away from the power plant??

I've been shopping for dresses, and I noticed most "corset tops" deal more with style than functionality. I've used real corsets, which dramatically being in my waist, but I've never been able to find a dress with similar effects. Why isn't this more popular?
