I never trusted polar coordinates.
It is circular logic.

You would need to have been aged about 17, and listening to Pink Floyd in 1973. That makes you about 70 now.

Or been about 10 at the time with a teenaged stereophile brother. Some of us youngests are head of our time.

Really? How disappointing I had already started to fold my own black hole...

Mythbusters managed 11. But started with a piece of paper that fit in an airplane hangar.

The assumption I think is standard A4 or letter.
… although those would also fit in an airplane hangar …

 

[Bandersnatch]

Even if you were somehow able to fold it as many times as you'd like, it still wouldn't work. You'd be turning the sheet into a thin, long thread. So you're not compacting the mass beyond the sixth fold, when an A4 most resembles a cube.
(that's the joke, I know, but being the ackchyually guy is the PF way)

All doorways should have a warning sign: Walking through this doorway too slowly may cause you to diffract.

All doorways should have a warning sign: Walking through this doorway too slowly may cause you to diffract.

But if you're too fast you might use the doorway next to it!

 

[phinds]

But if you're too fast you might use the doorway next to it!

I think that's only if you have a split personality.

 

[DrGreg]

But if you're too fast you might use the doorway next to it!

You could use both doorways, but only if nobody's looking.

 

[fresh_42]

I think that's only if you have a split personality.

Nope. I minimum of uncertainty is enough.

Why is it that everyone is perfectly fine with imaginary numbers, but throw in some imaginary physics and everyone gets an attitude?

But then I guess any physics that uses imaginary numbers is imaginary physics. This is getting complex.

What is the difference between Newtonian mechanics and Quantum mechanics?

Spoiler

Quantum mechanics have to use very tiny tools.

Hubble constant says hello.

 

[Orodruin]

Hubble constant says hello.

You mean $2.2\cdot 10^{-18}$ s^-1?

 

[Bandersnatch]

You mean $2.2\cdot 10^{-18}$ s^-1?

First of all, that should be in Hertz. But you know as well as I do, that in all literature it is given as 7.2 furlongs per fortnight per gigafathom.

Yeah, but you have to remember that the times they are a changin'. Trans people aren't what they used to be.

Cis people are all the same (side), but the para people are opposed.

Any Executive Orders regarding this?

I’m waiting for one that will settle the conflict between the Big-Endians and the Little-Endians (the real one about boiled eggs, not the byte-ordering tempest in a teapot).

And with tongue out of cheek again…. We do not have the bandwidth to effectively moderate a discussion that goes from humor to political so we’ll delete anything that looks like it might.

I can count to 1023 on my fingers …

59,048 if you can control the joints independently.

 

[Orodruin]

I cannot, unfortunately. Partly a result of being a football goalkeeper in my youth. (Balls hitting fingers at unfortunate angles is nothing I recommend.)

 

[Tom.G]

59,048 if you can control the joints independently.

OK, I'll bite. How did you get that number?

 

[Orodruin]

OK, I'll bite. How did you get that number?

I get $10^9$ if controlling each joint completely independently. 3 joints per finger except thumb, which has 2, but is opposable so that’s another degree of freedom. That means 15 joints per hand so $2^{30}-1$.

 

[Ibix]

OK, I'll bite. How did you get that number?

If you can control the joints independently you can have your finger straight or with one or two joints folded, so three states. The number is $3^{10}-1$.

I can do it - it's some sort of trick of lining up one joint so only the other one bends. But it's faintly uncomfortable in a way that suggests to me I'm overstressing something, so I usually stick to counting to 1023.

 

[Orodruin]

or with one or two joints folded

Ah, but there are three different states in each of those categories depending on which one or two joints you fold!

Even if you only count two joints per finger it is 4 states depending on the joint you fold.

 

[Ibix]

I get $10^9$ if controlling each joint completely independently. 3 joints per finger except thumb, which has 2, but is opposable so that’s another degree of freedom. That means 15 joints per hand so $2^{30}-1$.

I think I can only fold the lower joint or both, not the fully-independent flexibility required for this!
