Do you mean convict or acquit? Or can a judge just say ‘you’re stuck here until you say guilty’

Reply to comment by Tash11e in ELI5: Alzheimer's is dementia, but not all dementia is Alzheimer's. So what is the difference? by degobrah
To make a diagnostic of alzheimer you must first exclude all other causes and all reversible causes of dementia (hypothyroidism, depression, hydrocephalus)

Reply to comment by SirDuke6 in ELI5: Why does putting one foot out from under the blankets bring so much relief of heat while laying in bed? by SirDuke6
The feet are ideally suited to helping us keep a stable body temperature, for a few reasons.
They - like the hands - have a large surface area as well as specialised blood vessels which can be opened up to pass high volumes of blood through them and therefore offload heat quickly when required.
When not required, the blood vessels are constricted.
This, coupled with the fact that the feet (and hands) are at the end of our limbs and don't have much muscle (which produces heat) means that they cool down much more than other regions of the body.

In fact, you can use the solstices/equinoxes to “calibrate” any given solar calendar system.

If I remember my biology right, on average it takes 45 seconds for blood to make a full round-trip. Very fast in the aorta, much slower elsewhere.

You open the door and try to push it out.
And then the normal snow plows with the big wedges on the front exist, but many cities that get heavy snowfall also have things like industrial sized snow blowers (like the thing you see people push in their driveway, but the size of a Big truck.
As well as plain old construction equipment, front end loafers, etc.

Sounds like 12 Angry Men was a lot closer to reality than one might think, except the one guy who thought he was innocent managed to convince the other 11 who voted guilty.

Reply to comment by Derikoopa in eli5: Why couldn't a country in debt mint a coin of immense value and use it to pay off the debt? by Derikoopa
Other countries and banks use their money too. If a bank suddenly has its hands of a billion Imaginationland dollars it might exchange those dollars in to another currency it wants more by trading with a corporation that intends to use those Imaginationland dollars to make payments on a contract they have with a company in Imaginationland that needs to be paid out in Imaginationland dollars.
Or the bank might use those dollars to buy shares in Imaginationland corporations listed on the Imaginationland Stock Exchange, which would result in those billion dollars going in to the accounts of the Imaginationland corporation that issues those stocks for sale and then they'll use it to pay salaries, pay out vendors, etc
It'll always find its way in to circulation somewhere.

The earth is closer to the sun during the northern hemisphere's winter than during its summer.

Reply to comment by calbhollo in ELI5: What does Prior mean when used as a noun? by calbhollo
The term is also used in medical imaging to refer to an older study you use as a reference. Like, say, women past a certain age are offered a mammography screening every year or two, and here, the "prior" is last year's screening images. Radiologists will have the current (the primary) and several old (the priors) images on screen side by side so they can compare and spot any changes.

There are other reasons why your budgie might not be great at flying (wings clipped when young, not enough time outside of the cage, etc) but in the wild they are fantastic at flying and can turn on a dime.

Snow removal is a constant challenge in major cities. Sometimes it gets dumped into a nearby river, or gets trucked to an unused or underutilized parking lot or similar space.
If you're so snowed in that your door won't open (which is unlikely, but possible), you can open a window and climb out that way. But inward-opening doors are a ready-made solution to this, as you can always open the door inward and then start shoveling from the landing.

I live in New York. Property owner is responsible to clear their own driveway and provide a path on the sidewalk. Dept. of Sanitation goes on alert if a heavy snow storm is predicted. Sanitation folks make big overtime when there are storms. Snowplows, salt spreaders , and other equipment is on hand. They work until the snow is cleared. Regular sanitation pickups sometimes suffer, but everything eventually gets cleared away.

Vehicle-mounted snow plows for roads.
For sidewalks, citizens. There are laws that require everybody to shovel snow in front of their house and make it walkable.

Reply to ELI5: How do loans and credit cards work by idkmybffdee
Banks lend out deposits that other people make. They also profit from this through the net interest margin - banks pay people for depositing into a savings account (usually <1%) and lend money at a higher rate through credit cards, loans, mortgages etc at a higher rate.
Generally there’s a low risk that everyone is going to withdraw their deposits at the same time, or that everyone will not pay their credit card bills. If that happened they’d be in trouble and would need support from central/federal bank. Because of this it’s relatively safe to lend deposit fund’s.

Although the above comment is not wrong about the high speed of blood this is only the case close to the heart.
In smaller blood vessels, and especially in veins, blood flows much slower, as low as a couple of centimeters per second in the index finger [https://pubmed.ncbi.nlm.nih.gov/11284002/]
Not that this helps answer the original question by much, but this adds some nuance to the answer

People talking about heat transfer at your foot, but I think the bigger affect is how when you stick your foot out, you've created an opening in the blanket that allows warm out to leave and for cooler air to enter.

> Though I guess there must be some sort of control since the station is depleting its stock of gas, so it's not like they can order more gas and say they didn't sell what they had... (or can it?)
Conveniently, I wrote a handy-dandy tutorial er..uh...answer to a question about money laundering earlier this year that addresses supply-chain management and other money laundering tactics.

Because the owners are morons who don't understand the costs of cash money because there isn't a single fee like there is with card payments.

The soles of your feet have plenty of blood circulating through them, this combined with our feet's double-water pores and increased amount of pores per cm^2 makes it easier to shed heat through perspiration. Water is incredibly good at temperature regulation because of the energy required to heat and cool it to different states
Our palms and soles have an increased amount of sweat glands to provide greater friction with surfaces, our soles with ~600-700 pores per cm^2.
Edit: can't find a source for the "double water sweat glands", but I recall seeing something about it in a PBS documentary comparing humans to other primates, more specifically how sweating more efficiently may have given us the evolutionary advantage

Banks receive money from savers and pay them an interest rate. They lend that money to borrowers at a higher rate, giving them their profit margin. Over time this difference in the rate helps them to build up reserves (some of which a bank will pay to its shareholders; a building society or credit union can decrease the difference in rates instead) which they can also lend to borrowers. The reserves will obviously need to be sufficient in case that everyone decided to get their money back at the same time, which is why they offer a better rate on fixed-term savings (1 year, 2 years) where you can't access your money at all during that term, ensuring that they don't need to worry about suddenly having to return it.
