Because the FAA is not sure if your particular phone emits the same RF signals that the plane's systems use. Your phone probably won't interfere with the plane's navigation system, but the only way to be sure is to have the FAA certify every single device which is probably not going to happen given how often new models come out. The rules have been changed for quite a while now to allow you to use them in flight, that's why onboard WiFi is available now.

Dude you admit that you’re an idiot for not taking other people’s advice, and then you continue to not take other people’s advice. What wake up call do you need?

Reply to ELI5 why does taking a multi-vitamin on an empty stomach cause nausea, but something like Tylenol doesn’t? by sftysw
I was not aware that multivitamins had a tendency to cause nausea (they don't for me, personally). That said, I've been told that taking them on an empty stomach means it won't be absorbed nearly as well compared to with a meal. Perhaps the absorption and nausea are related?

Reply to comment by WeDriftEternal in ELI5: Why does a single franchise change directors so much? Wouldn’t it be better to have the save director for every movie? by cute_brute
For the time consideration there's also the practical aspect of it. Movies like in the Marvel Cinematic Universe are being filmed at a really fast rate with overlapping filming and production timelines, and that requires additional staff - one person can't direct two or three movies simultaneously.

Wave-particle duality doesn't mean that light is sometimes a wave and sometimes a particle, it means it's a third thing that has some things in common with both waves and particles
When we're measuring light passing through diffraction grating, it's most useful to treat it like a wave. When we're discussing the photoelectric effect it's best to treat it like a particle.
A good analogy I read in a reddit comment that I can no longer find: wave-particle duality as a concept is like if you saw a train and described it as exhibiting "horse-house duality", because it's sometimes like a horse in that it moves around and takes you to places, and sometimes like a house in that you can sit inside and it protects you from the elements. But you know it isn't a horse or a house, it's a third thing. If you're solving a question about how long it takes to travel somewhere you might model the train as being like a horse. If you're solving a question about how much stuff can fit inside of it, you might model it like a house. But you know neither of those are actually the truth.
All particles have wave-like properties. But for particles of fairly high mass, those wave-like properties are so small that it's easier to ignore them.

No, I don't think it does...unless I'm bad at reading (likely). Thorne 2day

Reply to Eli5: Some ice cream recipes put ice + salt outside the recipient to make it cool faster. But in the winter, salt is put on snow on the street to melt faster. Why one make cool and other melt? by zimobz
They both do the same thing. They both create an endothermic reaction (which sucks up heat and makes the surroundings cooler) by melting ice.
For streets, we don't care if they're cold as long as they don't have solid ice/snow on them. So melting accomplishes this.
For ice cream, we want the ice cream to become cold, so adding ice+salt outside accomplishes this by melting the ice and making the ice cream container cooler.

I assume you're talking about movie franchises.
You might not want the same director for each movie. Maybe you want to switch up the tone or style. Maybe a sequel is really different than the original. Maybe the director wants too much money to come back, maybe the director wants to leave to other projects, maybe the director sucks and you want them gone
Is there benefit to consistency? Yes in some cases, sure, but there's also benefit in change.
Lastly, in fast movie franchises, there's realistic time considerations. These can take a really long time to make and many people simply don't want to devote 5-10 years of their life to a single project.

Well I don’t consider it a full bottle cuz there are half gallons that are bigger. But yeah a normal size bottle I refer to as a 5th. Tbh I’m curious now why it’s called that lol. It’s just what I’ve always heard and said

Does your mutli-vitamin have iron? Iron can be the reason. I had to switch my prenatal vitamin to before bed during first trimester

Oh. Idk bro. It’s a 750ml bottle. Where I’m from we call it a fifth. Not sure why, but that’s just what we call it lol

Reply to comment by Taco__Bandito in ELI5 why can't you just plug in electric cars / why do you need a wall charger when it could just be built in by definetlynotaalien
You'd be silly to charge your EV with 120v at home, but it's not going to damage the battery, it's just slow. Most EV's actually come with a 120v cord, called a Level 1 charger, so you can do this in a pinch (and so the manufacturer can be assured that every buyer will be able to go home with a charging solution right away).
Your implication that 120v charging could cause permanent damage is completely bullshit; batteries can be damaged by excessive charge rates but not by slow charges.
Nor is 240v a trickle charge. Trickle charging is typically considered just enough to offset self-discharge, which even 1.5 kW Level 1 chargers can exceed. Level 2 240v charging is a "normal" charge, and is generally around 0.1C (a 10-hour charge), which is very safe for most battery chemistries. Level 3 DC fast-charging is the fast option, and the only one that really causes extra wear and tear.

Reply to comment by gribson in ELI5 why fraudsters like Anna Sorokin managed to deposit bad checks and immediately withdraw cash elsewhere without banks stopping it? by 6horrigoth
Yes, I know how it's done! Every check has written on it the bank (routing number) and the bank's account number. The numbers are written in magnetic ink and read with a magnetic check reader.
However, not all banks use the fancy magnetic equipment. In the very old days, there would literally be bank courriers with bags of checks who would meet at a "clearing house" to swap all their checks around. Big banks with lots of volume really wanted to automate the process; small banks were happier with just a manual process.
To make a "perpetually routed" check, print a routing number (bank number) using magnetic ink that points to a small, manually-sorting bank. Then cover that over with a non-magnetic ink routing number of a big bank.
Deposit the check into the big bank, and they will read the magnetic routing number and send it to the small bank. At the small bank, they will see that the check isn't really for them, and they will send it back to the big bank. And then the big bank read the magnetic routing number, and sends it back to the small bank...
Nowadays it seems like most banks work with the check optically, so the magnetic routing number isn't really needed any more.

if the nextflix series about Sorokin is accurate, she was able to do alot of what she did b/c of greed on the part of the bankers & various businesses she promised business to.
she convinced them that she's extremely wealthy, her money is just tied up in (insert some foreign exchange excuse) & that once it all clears, they stand to make a lot of money from doing business with her, but if they're gonna be sticklers about it now, she'll just take her business elsewhere.
she was able to skate on that for a couple years stringing along hotels, caterers, nightclubs, bank executives, etc before it all fell apart.

I like to think that’s the duality of man. We’re well aware of the self destruction cycle we are on. But choose to turn a blind eye because it doesn’t benefit us to be aware
