Reply to ELI5 What's "the hole" like in prison? by Runin28
The Hole conditions vary as to location, security level of institution; minimum, medium, or maximum security, Federal versus State prisons.
In some places, it’s simply an isolation cell. Typically no phone, no commissary, no extra food/drinks, no mail or visitors during an inmate’s stay in solitary. Infrequent showers, rare opportunities for recreation.
In some prisons, the inmate is only allowed to wear boxers and a tee shirt, or a suicide prevention apron.
In the worst cases the cell could be dark and is often filthy.
Most prisons are smoke free, so definitely no smoking in the hole.
Customarily, the mattress is confiscated during the daytime, so there’s no place to lie down or sit.
On prison documentaries, I have watched many, they call it "the jail within a jail".
As an investigator, I’ve been inside numerous jails and prisons and believe me, everyone is miserable. Understandably.

Once a blood-borne infection is sufficiently common, it doesn't matter which little biting parasite is carrying it. It may have jumped from rat-flea-human to human-louse-human transmission.

Apple has billions and billions in net profit running a ~24% margin on their flagship products. Dollar General nets about $29k per store per year. Apple makes that selling 100 phones.

My first job was across the street from a hospital (early 1990s). The cafeteria coffee was 29 cents if you brought your own mug (any size)
I brought a quart mug and stayed buzzed on high test health care worker coffee all day.
Many good reasons why the hospital offered that deal.

Reply to ELI5: How can CEOs/Officers/Execs/etc of a company buy their own stock it not be insider trading? by ksquires1988
Another restriction in addition to other comments, a lot of companies have rules saying senior executives have to maintain a certain amount of stock to hold their position. This means they often can't sell substantial proportions of their holding or else they lose their position and have to wait until they leave the company.
Let's say they need to hold a million shares and get 100 thousand a year as part of their compensation, yes they can convert those 100k into cash, but the remainder is tied up.

Great point. McDs doesn't sell the most burgers by having the best burger, they do it by having a convenient known item that is reliably standard across the country.

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
Input lag will be decreased by up to 1 frame of what the monitor can display.
Say you have a 60hz monitor and try to render at 120fps, the completed images are sent 0.5 frames earlier(counting with 60fps as a base). You try to render at 300fps, the images arrive at 1/5th of the original 60's 1, so you win the remaining 0.8 frames.
As you can guess, this is most of the time not worth it though, as in that last example the GPU still does 5 times the work just for a marginal increase.
If you have a monitor that has Freesync/Gsync, the ready frames get sent immediately, so no need to render above the monitor's refresh rate.

I highly recommend watching PBS space time on YouTube. Great host with amazing graphics to give you a way to follow along.
I wish I watched it while getting my degree.

>generally there's less money to be made in cheaper products. Compare a Dollar General to an Apple Store, it's pretty obvious which company is more successful.
Ummm...Dollar Gen will open more stores this year than Apple has in total. You used a Really bad example. See Walmart. There's lots of money to be made in high volume low markup sales.

Reply to eli5: when the sun swallows mercury in 4 billion years, how is that going to affect earth? by grass-whore
When the sun turns into a red giant it will swell to a size large enough to possibly swallow the Earth, if not be very close to it. So either our planet will also be destroyed or it will be so close that it would look like what Mercury does right now.

Reply to ELI5: How can CEOs/Officers/Execs/etc of a company buy their own stock it not be insider trading? by ksquires1988
Short version? They can't.
Long version? Can you give a more explicit example of what you are asking? Beascue your question doesn't make sense completely.
Nearly all CEO/C-Suite members of major companies have no active involvement in the trading of their stock, to avoid this exact issue.
Meaning, when they buy and when they sell are pre-determined by the trading windows the company establishes. C-suite members don't "buy" stock in the traditional sense, they get stock grants as part of their compensation package, or some employee stock purchase program, again the timing of which they have no control over.
How MUCH they sell may have some leeway although I'm sure there are guidelines. But C-Suite execs likely hold stock as long as they can while it's going up, and they may be able to sell more (or less) in the defined periods based on some insider knowledge, although again they can't control the timing so as to avoid any insider trading rules.
The only other way a C-suite exec can buy their own stock is part of say in index or other fund (which I'm sure doesn't count when they sell) or if they buy common stock on the market.
It's only in this last case where there might be some "insider" trading but I'm not aware of any situation where a CEO or other exec has purchased common stock of their own company, to sell later based on inside knowledge. I'm sure it's happened, but it's going to be very uncommon as this action would cause ALL KINDS of red flags to be raised.

They do. You can buy the same ingredients and equipment at home and make it yourself.
When you buy coffee from Starbucks or whoever you are also paying for
- Someone to make it for you.
- Somewhere for them to work and possibly somewhere warm for you to sit whilst you drink it.
- Someone to have purchased the equipment that you would otherwise have to buy up front.
Coffee shops also have to be located in high footfall locations where rent is going to be higher than your kitchen. Almost all of the cost to the retailer in providing you with the cup of coffee is the cost of providing the convenience rather than the product. But convenience still costs them money.

What we feel as temperature is actually the difference in temperature between ourselves and the environment. Our bodies are constantly giving off heat, so when we're in warmer environments we can't give off as much heat, making us feel warmer. It's like filling a sink with an overflow drain. If that hole is clogged (too much clothes) or more water enters the sink than can be drained (too hot of an environment), the sink overflows (we feel warm)

...but it still won't have a magnetic field, so it won't be able to hold on to a thick atmosphere regardless.
Mars already isn't that cold. On a warm day near Mars' equator, you could walk around in a sweater quite comfortably provided you had pressurized oxygen to breathe.

So you’re smarter about running a coffee biz than Starbucks? Any advice you want to give to astrophysicists about figuring out that whole big bang thingy?

Rats were likely not the culprits, rather it was lice spreading from human to human.

Reply to Eli5 if a phone number is 7 digits then how aren't there more people with the same number? by FrozenKyrie
There are something like 335 area codes in USA (first 3 digits).
After that, you have 9000000 possible combinations for a 7-digit number. N=1st×2nd×3rd×4th×5th×6th×7th=9×10×10×10×10×10×10=9×106N=9000000
9000000 x 335 = 3,015,000,000, which is roughly 9x the population of USA. And, we have not yet exhausted all the possible the area code (first 3 digits).

Suppose we have a 1% chance that something happens.
The chance it doesn't happen the first time is 99%.
The chance it doesn't happen the second time is 99%, independently of the first (we do need some degree of independence here, or your statement isn't true). So the chance it didn't happen either of the first two times is 99% times 99%, or 0.99 times 0.99, or 0.9801.
The chance it doesn't happen the third time, still 99%. So the chance it didn't happen any of the first three times is now 0.99 times 0.99 times 0.99.
You can hopefully see a pattern. The chance for the event to fail every one of the first n times is 0.99 times 0.99 times ... times 0.99, n times. In other words, that chance is 0.99^(n). And the limit of 0.99^n as n goes to infinity is 0, meaning that the probability that you manage to dodge your low probability outcome gets closer and closer to zero the larger the number of attempts you have.
Nothing about this depended on the exact 1% / 99% probabilities. All we needed was for that 99% to be less than 100%, i.e., for the 1% to be greater than 0%. As long as that's true, given some non-zero probability of success p, (1-p)^n always goes to 0 as n -> infinity (and therefore the chance you fail every time goes to zero as well).
