It’s not that easy, but it’s how we do it.

In mainstream America, at least:
-Your first name is what people call you by.
-Pretty much everybody has middle names but most people don't use them outside of legal paperwork. Often people will give their kids middle names to honor older relatives' first names. You can also just pick something that sounds good with the kid's first name. Having more than one middle name happens sometimes, there's no law restricting you to just one.
-Your last name is your family name. Usually it comes from your father or husband, but there is no law for choosing last names, so there are a lot of alternatives. Some people, especially those of latin american descent, will give their kids two last names.

Once you've excluded all other causes, it must necessarily be that cause, no?

I could swear it was a nerve thing. That makes so much sense, thanks! Haven’t been drinking enough water lately.

Reply to comment by Hoppingmad99 in ELI5: Why is it that, at some gas stations, it’s cheaper to pay with cash instead a credit card? by tgjj530
>costs of cash money because there isn't a single fee like there is with card payments
There can be. Some banks will charge commercial deposit customers a fee for their cash deposits based on the amount of cash being deposited (usually once they cross some threshold, such as $.0075 per $100 for cash deposits exceeding $10,000 during the statement cycle). Then they will also be charged by the bank for change orders to replenish their cash drawer and keeping appropriate change on hand.

Names and naming conventions differ around the world. Documentation of names differs around the world, too. It's really, really culture specific. For example, the United States (default) is 3 names: given name #1, given name #2, and surname, in that order. But, sometimes there are 4 (looking at the Catholics): given, given, religious, and surname or given, religious, given, surname. In Korea, it's surname, given name (inherited), lucky name (Kim Jong Un's surname is Kim and his given name is Un) In Iceland, it's given name and (parents' given name)-son or given name and (parent's given name)-dottir. So Ezra Emmasdottir or Carl Gustavson (as examples).

Our last name IS our father’s name. What we have is first name, middle name (mother’s maiden name), and last name (father’s surname).
Note: We’re both Filipinos I assume.

Reply to ELI5: How do loans and credit cards work by idkmybffdee
Another thing to mention: home mortgages (as well as student loans) are bought out by government programs (eg Fannie Mae). So the government then owns the loan, and gets most of the interest paid on it. This also frees up the original bank's money, so that they can continue making more loans.

I feel the need to clarify that 'injected' here means 'squirted into the vagina' and not 'injected into the veins with a syringe'.

Reply to comment by DrFafnir in ELI5: How is vehicle suspension ‘tuned’ for local (i.e. country) conditions? by KDNA-AUST
Cheaper; seamless; more elastic and tougher; more easily resurfaced; not prone to potholes; suits the terrain. There’s no perfect road surface, but you can choose the one that is optimal. Chipseal is great for windy highways. Hot mix asphalt is mainly used in build-up residential areas and on motorways. We don’t really use concrete for roads at all.

Reply to comment by Zbignich in Eli5: How do cities dig out of massive amounts of snow? by OutrageousAd6177
Yeah, but the snow accumulates when it stays below freezing all winter. I remember when I lived in Alaska working on an Air Force base; plows and snow removal trucks would pile up the snow all along the side of the taxi ways. By the end of winter it would be over 15 feet tall and wouldn't melt until the middle of spring. They'd also dump literal tons of salt weekly until they found that it attracted moose. There was so much salt it killed off enormous patches of grass. Don't cities that have to constantly salt the roads have to deal with the ecological effects of dumping all that salt that eventually makes it up streams and waterways? I get they plow it off the streets but if it snows for 2 or 3 days straight, most people underestimate the enormous amount of snow that generates, especially if it stays frozen; where do they store it all?

To quote Moby-Dick:
"We felt very nice and snug, the more so since it was so chilly out of doors; indeed out of bed-clothes too, seeing that there was no fire in the room. The more so, I say, because truly to enjoy bodily warmth, some small part of you must be cold, for there is no quality in this world that is not what it is merely by contrast. Nothing exists in itself."

Not really. When you get out of a hot shower and move into another room you feel cold because there's a lot of water evaporating off your skin, taking latent heat with it. Also, if you have ever been very cold you will know that just sitting in front of a fire doesn't immediately make you feel warm; even though you are warming up straight away it takes time for you to feel warm.

Some cities plow and load the snow onto trucks that take it to some unused area where it melts.
IIRC Toronto melts its snow and the water goes into underground storm sewers.

100% this. Heat transfer from the foot itself is definitely a factor, but I don't think it's the biggest one. While by no means sealed, the air within the blanket becomes pretty stagnant and holds heat while you're underneath it. When you stick your foot out you are creating a significant opening as well as air currents and turbulence from the movement that allows a large exchange of warm air under the blanket with cold air from the room.
You can easily test this by very gently poking your foot out of the covers while keeping them tightly wrapped around your ankle. You don't get the same cooling effect (I just tried it while I was writing this).
P.s. if I'm hot in bed I just kick my leg up high, which lifts the covers and lets all the warm air out/cold air in. Don't need to leave my foot stuck out to be quickly cooled down.

Reply to comment by boytoy421 in ELI5 why would we not be able to venture into space using rockets If Earth was 50% larger in diameter? by ShoulderHuge420
Sure!
A ground based acceleration on it's own isn't really an option - the speed needed for escape velocity is well into hypersonic speeds so you'd burn up, but launching into a low earth orbit with only small rockets to provide corrections is physically possible. As you mention though, that wouldn't work for astronauts, just cargo.
But a part approach with a ground launch then rockets is absolutely possible to claw back some of the limits from the rocket equation.
I believe there's a company called Spinlaunch who are developing a system like this (not for humans sadly) where the rocket is accelerated by a spinning arm in a vacuum sealed chamber before being launched.
In general, getting objects going fast enough without an enormous launch tube is a bit of an engineering challenge. Also, I guess given we are not in the 50% larger scenario people are happy with rockets.
