Reply to eli5 how fast charging works for phones. by Phoenix_3222
Fast charging does damage battery health, this is why many switch to normal/slow charging once you hit 80%.
If you are the kind to have a new phone every 1-3 years, then it’s not gonna matter; but if you are planning to have it for like 6yrs, then only fast charge when needed.

It actually has to do with crystalline structures of iron/carbon elements that form within the steel, IIRC.
I think it's this video that explains it well, if it's not this one, it's #2 or #4 in the same series: https://youtu.be/r1z6-h7XACg

Very brief and perfect explanation. A true Eli5 should be like that.

Reply to comment by georgecoffey in eli5 What is the difference between Iron and Steel? by georgecoffey
The commonly used divide between pure iron and steel is around 0.02% carbon, between steel and cast iron is 2.14% of carbon. For more complex alloys, where there isn't just steel and carbon but a sizeable portion of other things, it can be complicated.

The algae bloom also limits the transfer of oxygen from the air to the body of water by creating a layer that blocks adsorption. The surface agitation is dampened dramatically by the floating mats, thus lowering the uptake of oxygen by a large percentage (that I can’t remember, so I don’t want to quote it, but it’s over 50%).
More simply, the floating mats of algae cut down the oxygen and create a blocking layer so very little oxygen gets through it.

This is why I am asking this, they are both alloys of iron and carbon, but is there an exact divide? Is it just some percentage everyone agrees on? Does each alloy get assigned to one group? And if they do, what defines what group they get assigned to?

The more photosites, the higher the resolution. The bigger the photosites, the more sensitive they are and therefore the less noisy they are. It's up to the designers to balance resolution and sensitivity for their designs.
It's possible to take a high resolution image and reduce the noise by averaging neighbouring pixels which also reduces resolution. So, to some extent, you can do the trade off in software. You still lose out with very small photosites because the borders between sites are a fixed width, meaning a bigger percentage of the sensor isn't detecting light. Also, reading out more pixels takes longer which can limit camera frame rates and use more power, causing issues with overheating for video applications.

So, basically, too many algae leads to not enough algae?

Reply to comment by BaLance_95 in ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside
Lets just make up some numbers
Imagine your screen refreshes at 100hz 10 ms per frame with a perfect sync your input will be delayed by that 10 ms.
But what if you ran 200 fps, 5 ms. Well now your input is only delayed by 5 ms because a frame is being drawn every 5 ms and your GPU will only be holding on to that newest frame created every 5 ms to submit to the monitor
This latency would be addative to any latency from mouse/keyboard to computer as well as your monitor's processing time known as input latency tagged as "Lag" in tftcentral reviews
This example Acer Nitro XV273 X review noted that particular monitor they could only estimate potentially 0.5 ms of input latency but marked it as 0 as the estimate was not an actual measurement and 2 ms of grey to grey response times giving it a total input latency of 2 ms. Whereas the average range one may see goes from 3 to 8 ms.
Also worth noting that processing time of 100 ms on a television isn't unusual and that's why TVs are generally not recommended for gaming use.

I appreciate your explanations, and I get it, but is there something you can point to for the point at which you "cross over" from the different types of alloys called "iron" to ones called "steel". If someone handed you a lump of ferrous metal and said "is this iron or steel" what would you look for to answer that question?

You are directionally thinking of a geoengineering method called ocean fertilization. Using iron in the middle of the ocean where plankton normally couldn’t grow to stimulate blooms.

So what you're saying is there is no clear difference and it's more of a spectrum? I hope that's how it is, but it seems people want them as different categories, but also never to be able to define the difference in clear terms

pack/tribe behaviour, for a couple main reasons:
-
showing that we enjoy something, or feel safe, and advertising that fact to the other pack members around us (as opposed to a warning or panic noise for example)
-
belonging to the group - showing that we fit in to the rest of our group and aren't an outsider (consider "that humourless bastard" who never quite fits in, or the "has no idea what just happened but is laughing anyway" people)

Cast iron has carbon + iron, so that can't be it

Reply to ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside
This is actually true only in specific cases. If you will use resolution that won't create equal square blocks that can be summarized equally (how this works was explained by other people), you will actually get less crisp image than native resolution.
So if you have 1920x1080 monitor, but you will use resolution lower than 3840x2160, you will get less edges, but image may be less crisp than 1920x1080 because of "approximation". Since we lack informations to properly descale image, it uses algorithm to figure out best possible result. Which varies and with low resolution difference image is more noisy, which means it's less sharp in result. It is more visible on displays with lower resolution. 900p image on 720p display will be visibly less sharp than 1440p image on 1080p display.
It's most visible with text if you set higher resolution on whole game instead of using internal scaler that renders only 3D objects at higher res while 2D HUD stays at native resolution.

Reply to comment by Chii in ELI5: What is imputed income? by RylieSensei
Imputed income that comes from employment is usually taxable. The company might automatically cover the taxes on the imputed income, though (which is then itself income that is taxable).
Imputed income from owning a house wouldn't be, as there is no taxable event. (Although there might well be property taxes that achieve a similar result.)

NA just means no turbo or super. Once you have one of those it's forced induction and no longer naturally aspirated.

No worries, I mentioned it as adding bubblers/fountains tends to be the go to solution for the well meaning but uniformed. I get why people do it, it seems logical. But it’s another example of why common sense is not always the right answer.
A much better solution (after reducing the nutrient input that is) is to increase the number of large aquatic plants (macrophytes). These take up the nutrients which suppresses the algae growth.

Actually crossing oceans meant you had to understand the time was different everywhere. Once Harrison came up with a clock that could keep accurate enough time so a mariner knew what time it was back at the prime meridian, mariners could determine their longitude.

Reply to eli5 how fast charging works for phones. by Phoenix_3222
"Fast charging" is not one specific protocol anymore - it depends on the brand and the specific model of phone, as well as which specific charger you're using. For Samsung for example there is now regular charging at 15W, 'fast charging' at 25W, and 'super fast' which garuntees 25W and can go up to 45W. But I believe a random charger that provides like, 18W, will still say "fast charging" so long as it is getting over 15W, but obviously an 18W charger is still going to charge slower than a 25W charger.
