Anything for formal wear is all about looks and trying to show status. That is their purpose.

Or die of heat exposure in the sun.
Or die from infected scratches in forests.
Or insect bites.
Etc. Clothes are the first layer of protection from so many things.

Reply to comment by racecarthedestroyer in ELI5: What is the fastest way to stop a car with a manual gearbox ? by navenarf
I engine brake all the time with my automatic. My honda accord has slappy flaps (paddle shifters). Turns out my transmission is considered an "automated manual" meaning that it's basically a manual but with electro-hydraulically controlled clutches on each gear, controlled by a computer (unless put in sport mode).

Reply to comment by jlcooke in ELI5: In simple terms what are Maxwell’s equations and how do they work and what do they mean? by whocaresfuckthisshit
I would say it's really just one number (epsilon-naught). What we call a magnetic field is just the effects of special relativity once you start moving charges. The speed of light is a fundamental property of spacetime, so it shows up once you start making relativistic corrections to electric fields, but you knew that going in so I wouldn't call it a property of electricity & magnetism. Once you have e0 and you know about special relativity, then you know what u0 has to be.

I was sliding down an icy hill in Lake Tahoe once. Locked up the wheels in the Subaru, shifted into reverse, popped the clutch and floored the gas pedal. The car stopped so fast. Let’s just say, that your brain does not want you to do this. For some reason, it just came to me.

Don’t discount mechanical aeration, as a fast way to remediate.

So are pine needles, which survive freezing temperatures without thermo regulation.
They do it by, in part, having less water content. Less water means less ice which means less or no cell rupturing from ice shards

>Like ea for example generally has a hands off approach..they give the dev team a bag of money and then say make your game but I expect 2 bags of money back idc how your get it.
Sounds awfully a lot like a fetch quest, no wonder these guys produce videogames lol

Clothes are shelter, just like housing is shelter. The human body developed to survive in a very specific environment, but 99% of people don't live in that environment today.
Some of the native peoples in the Amazon and the Congo don't regularly wear much clothes. But they also never get cold weather, and have 24/7 shelter from the sun and rain because they live in dense forests.
Every other society on Earth developed customs of wearing clothes because the sun would burn their skin, the rain would give them hypothermia, and winter would freeze them to death.
You cab survive now without clothes because society has built an environment around you to let you do that. You live in a box that protects you from the weather and sun, and you travel to other boxes that protect you from the weather and sun. In between, you travel in various boxes that protect you from the weather and sun.

It is, formally speaking, a different unit. But for our purposes here on the Earth, where the vast majority of practical use of the units is conducted, the two are proportional and that proportionality is constant enough for the difference not to matter.

You don’t need a tie nobody needs to look like that. Wear one if you wanna be like everyone else. Don’t if you don’t. I’ve gone to weddings and charity galas wearing a polo under my jacket instead of a button up shirt and tie, way more comfortable and frankly if anyone had anything to say about it they sure as shit didn’t say it to me so I really can’t find any fucks to give. Fuck a tie.

And, for reasons to do with farming (planting crops/harvesting/etc) there was a very real need to learn this.
People were not stupid in olden times: they just had less knowledge.

Reply to comment by ace5762 in Eli5: why are some airplane jet engines under the wings and some on the vertical stabilizer? by Sad-Carrot-4397
ETOPS is (was) for planes with two engines. The thinking was that if one engine failed, you only have one engine in reserve. If it, too, fails, the passengers will be swimming for hours or days before help can arrive. Overland, the loss of both engines leaves the pilots with one final option before passengers are endangered: A dead-stick landing on the ground (See: "Gimli Glider"), or near enough to land for the passengers to be quickly rescued (See: "Miracle on the Hudson"). Flying out to sea, you can't expect a quick rescue after a forced landing. Regulatory authorities don't like it when you are operating with no redundancy left. They really hated the idea of twin engine aircraft flying over the ocean, just two failures away from catastrophe.
ETOPS initially said that If you wanted to fly a route that took you more than 60 minutes from land, you couldn't use a twin-engine plane. You had to find a plane with more than two engines.
You don't want to fly a three engines plane because it is less economical, but you are required by law to use at least three engines. You could use four, but that's even less economical. There was no practical need for three-engine aircraft (outside of extraordinarily rare double-emergency situations), but the law regulating twin-engine planes prohibited them from making these flights. Airlines needed three-engine planes to bypass this law.
ETOPS certification was incrementally expanded from 60 minutes to 370 minutes for some twin-engine aircraft and airlines. If you could prove your engines were reliable enough, and your maintenance program thorough enough, you could acquire additional certification to fly farther from land. With such certification available, more routes can be legally operated with twin-engine aircraft. Fewer routes legally require three engines. Presently, 99.7% of the Earth's surface is within 370 minutes single-engine flight time of a major airport. 99.7% of all possible flights can be undertaken with twin-engine aircraft. There was never much practical use for a three-engine aircraft in the first place; now there is only 0.3% of a legal requirement left. It's now cheaper to slightly alter one of the few remaining routes that twins can't legally perform than to maintain fleets of tri-jets to perform them. (Basically, they have to fly around the south pole, rather than directly over it, so they stay within 370 minutes of airports in South America, Africa, Australia, etc.)
Even 4-engine aircraft are being replaced with twins. Boeing ended production of the four-engined 747 in favor of the twin-engine 777 with nearly the same capabilities, because carriers prefer jets with two huge engines instead of jets with four smaller engines. Twins are simply more efficient to operate. The only thing that stopped them from using twins was the law, and the law has stepped out of the way.
You are correct that I don't understand your point, but I think the problem is that I failed to adequately explain the law. Your criticism doesn't seem to address a situation the law was trying to regulate.

Reply to comment by Judge_T in eli5: What exactly does a "videogame publisher" do? by Judge_T
There's no fixed standard. Publishers usually do things their own way and it will depend on the situation. For example, Microsoft approached acquiring Bungie for Halo to launch the XBox. Sometimes studios are running low on funds, so they seek a publisher to support them until the game launches. They can reach out to each other directly, there are usually entire teams whose job is to manage these relationships. Alternatively, they could have networking events in industry conventions like the GDC (Game Developers Conference).
For 3 specifically they don't do this randomly. They will negotiate terms for a contract that both parties will have to sign. It's a contract where the publisher is selling their services for a price. In the software world, outright IP theft of things like game engines is rare because it's really easy to get caught. The publisher really only has to look at the distributed game to spot clear markers of it being based on Frostbite. Having a past record of good projects will definitely give the developers an easier time negotiating a contract over someone that doesn't. A publisher could definitely opt to publish a game with only a pitch from a studio with no experience if they wanted to. It's just not likely and more often than not they're going to ask for at least some evidence that they're not wasting their time.

Reply to ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside
Rendering more information, than what can be seen. Allows the system more spaces to decide where edges fade and the different combinations of colours should work.
Then once you take this information and squish it down to your monitor again, it can take that info and merge it down into a smoother and more accurate representation. So that instead of each pixel getting a twig color or sky color. It could be a shade in-between.
