Maybe I’d add “and that others could see/touch/smell/hear/taste” - clarifying around vivid imagination, synesthesia, and that reality should be shared. It’s the things all reasonable folks can agree about (given sufficient time and access).

Eh - surely this is because one party (rightly) had a platform of cutting police funding. Selfish explains most of this, surely?

Ah, so it’s the probability you win by playing randomly. Gotcha. That makes sense, it becomes a choice between 2 doors

Why do you have a P(x1) = 1/2 at the start? I’m not sure what x1 means if we don’t specify a strategy.

Agree that this is a circuit you should never use. But theoretically it could be a circuit that does… something? Maybe?

Would the tears and their paths make interesting circuits? Salt water is probably a reasonable conductor, but I’m not sure how to model the eyes.

Does the ama help? If so, how?

I imagine it as distracting, which might be enough to cope? But I’m not sure.

Oh that’s cool - I had heard one or two examples only. Is there some popular writeup of the story from Savant’s view?

An arithmetic miracle:

Let’s define a sequence. We will start with 1 and 1.

To get the next number, square the last, add 1, and divide by the second to last. a(n+1) = ( a(n)^2 +1 )/ a(n-1) So the fourth number is (2*2+1)/1 =5, while the next is (25+1)/2 = 13. The sequence is thus:

1, 1, 2, 5, 13, 34, …

If you keep computing (the numbers get large) you’ll see that every time we get an integer. But every step involves a division! Usually dividing things gives fractions.

This last is called the somos sequence, and it shows up in fairly deep algebra.

I now recall there was a numberphile with exactly that visualisation! It’s a clever visual

For the uninitiated, the monty Hall problem is a good one.

Start with 3 closed doors, and an announcer who knows what’s behind each. The announcer says that behind 2 of the doors is a goat, and behind the third door is a car student debt relief, but doesn’t tell you which door leads to which. They then let you pick a door, and you will get what’s behind the door. Before you open it, they open a different door than your choice and reveal a goat. Then the announcer says you are allowed to change your choice.

So should you switch?

The answer turns out to be yes. 2/3rds of the time you are better off switching. But even famous mathematicians didn’t believe it at first.

Note you’ll need the regions to be connected (or allow yourself to color things differently if they are the same ‘country’ but disconnected). I forget if this causes problems for any world map.

I want this to be true… is it?
