Companies lay out their rules in a document that says "these are the rules". Its generally pretty standard corporate stuff, of course, these rules can also be changed, especially by the person with the most votes... There isn't some independent authority, the company is in control of its owners, outside of any govt regulatory body rules to be followed.

By legal process, I mean, if you're doing illegal stuff you may be able to be kicked out, its all a case by case basis.

In the crypto world, everything is massively manipulated and people on the outside can only guess at how things really work.

Theoretically, everyone buys and sells Tethers, but they just trust Tether so much that any time the price starts to drop below $1, clever people rush in to buy it, knowing they will later be able to sell it for $1.

Actually? Tether itself is probably buying those many of those Tethers to keep them at $1, and buying large numbers of them, and if they ever stopped the price would collapse.

But it's impossible to know. The crypto world is a crooked casino, and you know everything is fixed but you're never sure exactly how. Is the blackjack dealer stacking the deck against you? Are the slot machine payoff tables completely different from what they say? Are the big winners secretly working for the casino? You never really know.

No, but it IS still equivalent to repeated addition. It just gets more complicated in how that's represented symbolically. The fundamental operation doesn't change just because we use less clean symbology of rational and irrational numbers. The concept is still the same. Multiplication is an operation upon addition.

You would be able to win any vote. So it would have to be something other than that, like doing illegal things that may force you out or perhaps other shareholders doing nefarious things purposefully causing harm or crazy shit.

Pretty much when you get into these situations, some weird or illegal stuff needs to happen to push you out involuntarily.

>We can’t change the area of contact between the ice and the metal tube containing the cream

We absolutely can, we can add salt. I have studied advanced physics, but more importantly I have been a professional chef and I understand how ice cream is made.

You can absolutely do this. You add salt.

That's literally why we add salt.

>Because the salty ice is colder

Ice does not get salty. Ice is a solid, and it is a unique solid which expands when it cools. Because of this property when you add any weight to it, it will compact, and melt.

If you don't agree with this, or can disprove this in some capacity then feel free to do so.

A cube of iron that is chilled to absolute zero, if stepped on, isn't going to compact any further. A cube of ice will.

>So yes, the freezing point is relevant.

How? Salt's affect on ice diminishes as the temperature drops. By the point we're talking about absolute zero the affect of salt on ice would be almost zero.

edit: I suppose the iron would compact slightly, but not to the magnitude of ice, and the energy transfer relative to the melting point would be negligible for these purposes, but if you were to step on ice with boots covered in salt, and push the salt down into the ice... it will melt faster, and increase the surface area of the inner shell, which has nothing to do with the freezing point. The ice is already melting, you're just helping it melt faster by introducing water which has a lower freezing point than the solid you're trying to melt.

It's simply a fraction of pi. You don't need to think of the parenthesis as multiplication per se, just that it's a modifier that represents the leftover.

You can say "half of 4 is 2", "a quarter of 12 is 3". In a similar vein, .1415...th of pi is 0.44...

No, the rules apply through the real numbers. It's just easier to visualize in integers.

Let's take 1.4 × 2.5. Both are non-integers.

You can still interpret this as taking 1.4 and adding it to itself 2.5 times: 1.4 + 1.4 + 0.7 = 3.5

Another example, take pi, an irrational number. pi × pi = pi + pi + pi + (.1415...)pi = 9.8696...

Probably no, although some exceptions apply

First, doing illegal things may allow them to vote you out regardless, but thats more a case-by-case basis.

So for pure voting, generally you have 1 share 1 vote. So if you own 75%, of course you can win any vote.

However, in some cases, its not 1 share 1 vote. Some shares may be worth more than 1 vote. This is by design. Stocks can be dividend into different "classes". So a Class A share may be 10 votes, and a class B share may be 1 vote.

So what happens if I own 75% of a company, but they are all Class B shares with 1 vote vs maybe someone who only owns 25% of the company, but those are Class A shares with 10 votes! Things get weird

In reality, its common for founders in the early stages of companies who sell off stock for money, to create these classes and get shares with more votes, so that while they may only own 25% of the company, they still have the majority votes.

So… I’ve never seen someone use so much space to talk about something they don’t seem to understand very well. I’m not an expert, but I do have a degree in physics and have taken several college level thermodynamics classes.

Your last point in particular is contradictory. And really hits the nail on the head.

Heat transfer (in conduction at least) depends on several things - the area of contact between objects, the coefficient of heat transfer, and the difference of temperature between the objects. (Q/t=kA(T1-T2)/d)

We can’t change the area of contact between the ice and the metal tube containing the cream. We can’t change the coefficient either (not meaningfully). What we CAN change is the difference in temperature-by lowering the freezing point of the ice, we lower the temperature the ice can raise to before it begins melting. A mixture that is partially ice and partially water (such as a mass of melting ice in an ice cream maker) will ALWAYS be at the freezing temperature (0 C for normal ice, or -5ish C for salty ice).

Because the salty ice is colder, heat is transferred more rapidly due to the difference in temperature being greater.

So yes, the freezing point is relevant. Ice cannot have a higher temperature than its freezing point. Therefore salty ice having a lower freezing point means greater temperature difference and therefore greater heat transfer and therefore faster freezing ice cream. Does that make sense?
