Reply to comment by DiamondIceNS in ELI5 - When filling multiple choice bubbles at random why only go with 1 letter? by Stellar_Panda
Okay, why is selecting a straight line of 'C's better than filling in with no rhyme or reason (like the test probably would have looked like if you actually took it?) I think this is what my question boils down to.
If everything is 1/4 why would always choosing the same answer increase your chances? (Ignoring the whole 'C' is actually a better guess findings.) It doesn't right?-

It's amazing! They give pretty strong anaesthesia alongside but it's still not the most comfortable

Reply to ELI5: If drinking salt water further dehydrates the body, why is saline used to treated dehydration? by Dartualexmachina
Some important concepts
-
Salt sucks up water. Water draws out salts. This is known as osmosis.
-
Your body Is a bag of salty soup. We call these body salts "electrolytes". You need electrolytes to live, and the electrolytes need water to be useful..
-
Your body pees regularly to get rid of stuff it doesn't need. Your body will always need to pee, regardless of how many electrolytes that water holds
-
Sea water is MUCH saltier than Saline
In short, you need to keep a balancing act. You need a certain amount of electrolytes to function, and you need a certain amount of water to hold those electrolytes. Your body uses water for different things tho, so you need to keep that balanced.
When you drink sea water, the water is MUCH saltier than your body. Instead of your body absorbing the water, the salt sucks water out of you, and you pee it out. Your body has less water at the end of the day.
If you drink pure, unsalted water though, the opposite happens. You drink the water, your body is saltier than the water. The water sucks out salt from your body, and you pee it out. You loose electrolytes.
Now, you don't wanna lose water. Dehydration causes a tone of issues. You also don't wanna lose electrolytes. That can cause just as many issues
Saline is a happy balance. it's only a little less saltier than your body, which means your body can take in water, pee it out, and lose little to no electrolytes. This lets someone who's dehydrated gradually rehydrate, without a drastic change in anything else.
This gradual change is often really important, because your body isn't a machine. It slowly adapts to extreme changes like starvation and dehydration to help you stay alive in those states. Quickly changing their intake (like giving a severely dehydrated person a gallon of fresh water) can really mess their body up if they aren't gradually introduced to it.

Reply to comment by BobbyThrowaway6969 in ELI5: Why do computers need GPUs (integrated or external)? What information is the CPU sending to the GPU that it can't just send to a display? by WeirdGamerAidan
No, most GPUs haven't had vector instructions for maybe a decade. Modern GPUs use SIMD waves for parallelization with scalar instructions.

That's f-ing AWESOME!
But that sounds incredibly painful.

There are many people who contributed, but Nixon was the key to execution and propaganda following. All for the vietnam war effort and disenfranchising communities most likely to oppose it.

It's called double pane. Two pieces of glass with air trapped in between. More expensive ones use argon or other noble gasses that transmit heat even slower. They're not common in older homes but most newer ones I've seen have them. The issue with upgrading is just the expense. You get used to your monthly utility bill but spending thousands on new windows that aren't "broken" can be difficult, even if they will pay off eventually.
There are also triple pane windows that are even more efficient but for the price difference they typically aren't worth it in most climates.

Reply to comment by tyler1128 in ELI5: Why does the order of adjectives matter? by AbleReporter565
Teaching English as a foreign language relies on more than being able to speak English for this reason. Knowing the difference between "I've been painting the house" and "I've painted the house" is okay, but why isn't it, "I've been knowing my friend for five years"? English is a quirky language and it's quirks are fairly different from most other European languages.

Yeah, as the last Ice Age ended. At its lowest point, sea level was 400'+ below where it is today. That was about 20,000 years ago, then it raised steadily for 15,000 years.
About 5000 years ago sea level stabilized, and now it's rising faster than it has in thousands of years. The planet has seen huge swings in sea level -- human civilization has not.

Useful addition but not a rule or answer to the actual question. It's basically a systematic reiteration of the question. The rules that produce this pattern are AFAIK still to a large extend unknown.
Except for the latter two, that is: "Material" and "Purpose". These are actually quite easy to explain. What is called "purpose" here refers to simply compound heads that would form 1 word in other Germanic languages spelling, so obviously it comes closest to the noun. And "material" is a genitive that doesn't tolerate adjectives between it and its noun. "The wooden big table" is ungrammatical in a way pretty similar to "The table I saw of wood" is.

There's even a cream made of Bromelain which is used to treat burn victims in hospital. It eats up all the dead tissue so the burns can start to heal.

Insulated Glazing Units (IGU) are a thing where they make sense in terms of energy savings, and are often required by building code. They're less common in older buildings as we didn't used to be as energy conscious and their relative cost was higher.

Depends how you look at it. Their circuitry can handle vector math more efficiently

Reply to ELI5: what does ‘social media companies independently deplatforming individuals’ mean? by XinrongZou28
In short this would be preventing online social media platforms banning people from using their services for violations of their terms of service outside of their platform.
IE you said something on Facebook, which got you banned from twitter because it violated twitters rules.
Are you for or against? If you're for, then you might want to lean into how no violation of the agreement between the user and the service has occurred. If you're against, you'd lean into the rights of companies to choose who they do business with.

I kind of imagine this as a ping-pong ball going up and down. The ping-pong ball always travels at the speed of light.
Now ping-pong ball is put on a ship, and that ship starts travelling. The ping-pong ball is still moving at the speed of light, but as the ship travels faster and faster the ping-pong ball is moving sideways. From inside the ship the ping-pong ball is going up and down (and time stays normal, but only from the perspective of the observer that's travelling with the ping-pong ball). From an outsiders perspective the ping-pong ball is going to move in a zig-zag movement. As the ship goes faster the zig and zags will be longer and longer, and so (since the ball always travels at the speed of light) it's going to travel up and down slower.
Now. This is applied to all reactions between particles. Everything is going to move slower and slower since their movement is capped at the speed of light and more and more of their movement is taken up by keeping up with the movements in realspace. Until, when the ship travels at the speed of light, time becomes infinitely slow.

Double-glazing? It's very common here (the UK) - maybe you live somewhere hotter that doesn't need it.
