Reply to comment by DragoonXNucleon in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
>Government could fix this, but won't because captured capitalism.
This was a sarcastic post, right?
Have you seen the size of these batteries? Have you heard the precautions or watched how they're disassembled?
They're 480V. That's a terrifying voltage, nearly insta-death.
They're massive modules with loads of balance wires.
The 'gubberment' doesn't need to do anything- anyone can build a battery to fit there if there is an advantage for it.
This isn't a gas tank pressed between two plates, or a 'chopper' show where they beat some aluminum and weld it to hold gasoline.
This is a massive piece of critical engineering with extremely fatal consequences.
Frack, Boeing stuffed something in their planes and they caught fire because they didn't do it right.

Reply to comment by CFDietCoke in Eli5: Why are matress and laundromat stores often used for laundering money by Jojojoost010
True, but if your laundromat is showing much higher profitability than other laundromats in your area, the IRS is going to notice that and that could flag you for an audit. If you get audited, they will look at your utility consumption and compare it to industry standards.

Atoms on the periodic table are defined by the number of protons in the nucleus of the atom. It is possible to discover/create new atoms by adding new protons to a nucleus, but those large atoms tend to be very unstable (which is why we don't add them to the periodic table anymore). There is a theoretical "island of stability" when atoms get large enough, but we are nowhere near being able to create atoms that large to test.
It is possible to create new compounds or molecules from existing atoms that we have already discovered, and those new molecules could have interesting new properties.

Yes, but they're incredibly unstable due to being highly radioactive. We make them by firing certain atoms at a target using particle accelerators

I know it is possible, but IRS agents are not going door to door looking up utility bill records for small time laundromats.

In that case it actually would be simple - the machines use X amount of water per load, so if your water bill shows you not using enough gallons of water to explain that extra $3500 in revenue, the IRS is going to want to know why.

Which is why the mattress story is probably fake.
But the sales could be reasonable, you just need to find enough people to buy a mattress.

Reply to comment by Averrences in ELi5: How are blizzards and winter storms like the one that happened in Buffalo formed? by ArinMun
Yeah definitely polar vortices can span multiple continents, this 2022 one hit NA and EU.
As for the storms yeah I don’t think there’s anything limiting it to the US, the US is just a highly unique for meteorology. You have stuff like tornado alley which occurs due to cold, dry air heading southeast from the coast, down over and along the rocky mtns that meets warm, moist air from the Gulf of Mexico, leading to the most active tornado zone in the entire world.
So like a buffalo storm is unlikely unless you live somewhere near a ton of water that hasn’t yet frozen over.
But as for the severity of the average storm; they’ll get worse around the world. EU as well.
Those EU heat waves in the summer? Theyrw kind of the reciprocal of what NA got. Could easily be the other way around or a shitty summer AND winter in one year etc.

It seems like you know what you're talking about but I don't understand. I have no idea what thermal energy or thermals are, so I'm totally lost with what role that plays. Are you able to explain this like you're talking to a 5 year old?

It can be swapped cell by cell, car knows which ones are done and which still have capacity. But it's not easy.
-anti theft -they want to see the car again to tell what could be done better, harder it is, more cars will come back because more people will be unable to do it in garage. -its new thing with new hazards

Algorithms, I saw other methods in the commets, but I like this one:
The square root of a number like 9 is 3, 9 is called the radicand. Now if you have x^½ = y then x/y = y. So the radicand decided by the results is the result. 9/3 = 3.
So let's try the following for say 16.
Guess: for example 6.
16/6 = 2.6667
Lets take the average of your guess and this number:
(2.6667+6)/2 = 4.3334
And try this number:
16/4.3334 = 3.692
Take the average:
(3.692+4.3334)/2 = 4.01
16/4.01 = 3.99
(4.01+3.99)/2 = 4
16/4 = 4
So 4²=16, the square root of 16 is 4. And you find a number that is pretty close really quickly.

It doesn't have to be a smoking gun - it just has to be odd enough to get noticed, which will prompt a deeper dive into the finances, which is the last thing you want.
The average laundromat has margins in the 25% range - if your margins are higher, that is going to draw some curiosity. If you run your machines more and your water usage is much higher than comparables, that is going to draw curiosity too.

>I think you are conflating "diplomat" and "Ambassador" a bit
Ambassadors are diplomats, but not necessarily vice versa, right? Ambassador is just a more permanent (not permanent, just longer lasting) appointment than a lot of other diplomats.

I certainly agree that there are much better ways. I just didn't think water consumption would be the smoking gun.

Loads of jobs at the U.S. Department of State do not require a college degree at all, though they get enough applicants with degrees that you need lots of experience to compete. Specifically, no degree is required to take the FSOT.
Oddly enough, the jobs which do require a college degree (things like IT) often do not require foreign language fluency for overseas postings. But then there's the question if those are technically "diplomats", as they are likely defined as "administrative and technical staff" rather than "diplomatic staff" under the Vienna convention.

Reply to comment by mfb- in ELI5 How do calculators get the square root of random numbers? by Mikinak77
I state here two mathematical facts used in the answer:
- for any positive numbers m and n, where m < n and m, n > 0, the following is true:
- m < (m + n) / 2 < n,
- where (m + n) / 2 is the average of numbers m and n
- m < (m + n) / 2 < n,
- for any numbers x > 1, it is true that:
- x < x * x = x^2,
- where x^2 is the square of x
- x < x * x = x^2,

There are multiple reasons why you can only buy things as assemblies.
Including having few parts to keep in stock. And some of these parts are not designed to be taken apart. Plus the labour to change the failed part of the assembly can be cost more then then new assembly. Assemblies are designed to reduce the overall cost. Especially with parts the rarely fail.
And as for you oxidation example. If you would take apart the column, clean the switch contacts. Charge the customer.
Now a week or year goes by, and the switch doesn’t work again. Either the contacts are still corroded or a spring broke inside. The customer would expect this to be covered. But since you didn’t replace any parts, there is no warranty. So either the tech or the shop does it for free. Or you loose a customer because they pay for the “same repair” again.
But if you replaced the switch, the odds of it failing again within the warranty period are much lower, because every component is new. And if something does go wrong, both the parts and labour are covered.
Now if you DIY, and don’t value your time. Then go ahead go for it.
Or if it’s an older vehicle and parts are discontinued, it may make sense to try and repair the part.

You could, sure, but laundromats are pretty low-margin businesses, so running with no load is going to eat away most of the profits and limit your laundering.
You also run into the issue with comparables. If your laundromat is doing much better than nearby laundromats, that is a red flag that could get you audited. If the foot traffic to your business doesn't match the number of loads you claim you ran (the average number of loads per person will be pretty static across laundromats) then you are going to have to explain why your business is so unique.
All in all, its going to get your business scrutinized, which is the last thing you want for a money laundering front.
That is why casinos and strip clubs are the best businesses for money laundering:
- Most people use cash (no paper trail)
- There is no "average" spend per customer (one guy could come in and drop 10k) and foot traffic doesn't correlate well with revenue
- The marginal cost is next to nothing
- Comparables are hard - your casino/club may just be higher end than the neighboring ones, explaining your higher revenue.

This is a great explanation, thank you !
I’m also curious, with climate change and changing of currents etc - is it more likely that the referenced storms and winter storms will be focused on North America? Or is there a chance this could similarly impact Northern Europe as well? (e.g - could the UK ever have to deal in the future with a polar vortex/ winter storm of this magnitude?)

Reply to ELI5 : Physical and Digital video games piracy protection. And how hackers are still able to find their way around it. by SolarSpud
PC owners technically have full admin rights to their operating systems, therefore with the correct knowledge and tools, they are able to inspect and modify any aspects of any programs running on it, including any game DRM checks.
Therefore all modern PC anti-piracy schemes are built on the principle of obfuscation, just scramble the piece of code and make it a huge headache for a human to descramble and reverse engineer to skip all the checks.
Therefore it is only a matter of time before all the checks are found. PC game publishers now only uses this time difference to cover themselves to sell most of the expected sales, and update the game once one major version has been cracked to protect their online gaming services as much as possible from cheating.
Console disc-based copy protection however still relies on hardware. Discs are produced to contain errors that are genuinely impossible to replicate as long as you don't have the original stamps, and the disc drives contain special firmware to look for those errors. Consoles check these areas to determine if a disc is genuine or a burned/pirated pressed copy.
Console digital copy protection works on the assumption that console owners DO NOT have full admin rights to the OS, and therefore the hardware encrypts EVERYTHING to prevent inspection and modification of the code as much as possible, guarding the code even from users.

Reply to ELI5 What is the purpose of continuously spinning a lasso before throwing it? by Asian_1nvasion
I know absolutely nothing about lassoing, but my common sense guess is that you are typically aiming at a moving target, so you want to keep the lasso as ready as possible so you can throw it the second you’re ready.

No they won't. You are trying to sound clever by thinking you "figured out a loophole" that disproves my statement.
Source: Owned 2 laundromats in my life. Was audited once. Never had to provide a utility report.
