Not infinite but [math]2^{63}[/math] is a very large number.

@claude is this true? it's unbelievable
https://www.youtube.com/watch?v=sfCLt0kTd5E

You can proof it by induction:

show ∑ₖ=1n 2ᵏ-1 = 2n–1 for all n≥1

Base: n=1
∑ₖ=11 2ᵏ-1 = 20 = 1
21–1 = 1

IH: assume ∑ₖ=1n 2ᵏ-1 = 2n–1
Show for n+1:
∑ₖ=1n+1 2ᵏ-1 = (∑ₖ=1n 2ᵏ-1) + 2n
= (2n–1) + 2n by IH
= 2·2n – 1
= 2n+1 – 1
Therefore, by induction, ∑ₖ=1n 2ᵏ-1 = 2n–1 for all n≥1.
Plug in n=64 to get 264–1 = 18,446,744,073,709,551,615

>rice on a chessboard is infinite
no such thing to explain.

After the 33:th square the rice on the board is already heavier than the world's heaviest tank, Panzer VIII Maus. That's what exponential growth does. It almost looks like it's getting infinite but it's not.

>>16704898

>>16704875
That makes about 535 billion tons of rice. 3590 times how much rice are produced in China in a year.

to process incomprehensibly large numbers we almost necessarily need to construct them in a useful manner. 2^64 is enough information to do some pretty cool things, but unlike "six take away three" we can never fathom 9 quintillion items.

Get this. By the last square of the checkerboard,
you can fit all 18.4 quintillion grains of milled rice
in about 40,386,961 silos each containing about
500,000 bushels of rice.

If the famous story holds true in this regard,
the king would have to fight the entire world
full of granaries a number of times over
to fulfill the reward of one man, and yet be
61 magnitudes short of all particles of the
universe--completely eclipsed by the mass
of ya moms ;)

>>16705077
The King could have handled this in a variety of clever ways.
All the King had to do was just laugh and say "Oh my you are such a clever fellow! I will certainly honor my promise! But it may take a long time to fully collect your reward. I will pay you ONE GRAIN OF RICE PER YEAR!"
or
"Here is my IOU for all that rice, once you have brought me all the sacks needed to haul it away you shall be paid."
or
"Fine then, on the first day you will receive one grain of rice, on the second day we will split one grain in half, making two grains of rice, then the next day one grain split into quarters to make four grains, and so on until you have been paid in full."

>>16705372
Rather astutely, the kind said that it would be better if instead of 2^64 of rice he would give a board 2^∞.
Of course, 2^∞ = ∞ = (1 + 2 + . . . ) = -1/12
And this is how fractional banking was born.

This is how you spend your limited time existing? Shitposting for attention and trying to spread disharmony amongst people you don't even know?

>>16704859 (OP)
I will try. But I am just an ordinary guy.
Basically its just analogous to demonstrating that every infinity contains an infinite number of infinities. WIth each of those infinties doing the same.
Or "Infinities all the way down" sort of thing. And infinities all the way up. Infinities in all directions, in all dimensions, The ultimate hall of mirrors.
Its open to interpenetration of course, depending on one's own philosophy of math, but some people use it as a way to mock the very concept of infinity. Those who subscribe to the notion just remark its just an interesting observation about the nature of their own particular of mathematics.
I have no particular opinion on the subject. But I do observe that the pure mathematicians tend to favor the former, or at least tolerate it, while the engineer types favor the practical applications and get irate when mocked for their pedantry.

>>16705003
In 2022, the total world rice production was approximately 776 million metric tonnes. The largest producers include China, India, and Indonesia.

>>16705388
The chessboard is clearly non-finite.
One can argue uncountably so.

Dude, thank you.
You just made Banach-Tarski seem completely normal. Over the Naturals, Integers, and Reals it is. It's only on the sphere where things start to get weird and you need AoC.

Let us be perfectly clear. Infinity is an affront to GOD and all that is good and decent. The Universe is finite and granular. There are no infinities, just like there are no unicorns or flying pigs ( unless you count police helicopters ).
Its time for Mankind to come to its senses and purge this Earth of all mention of infinity.
Brothers and Sisters of the ONE TRUE FINITE FAITH, it is time to rise and seize the Holy Land of Mathematics back from those GOD CURSED INFINITY LOVING SODOMITES!

Here's a comparison of the moon (left) and the rice if all the 18446744073709551615 grains of rice were put into a huge ball. It would have a diameter of 10.849 kilometers assuming rice density is 800 kg/m3 and one grain weighs 0.029 grams.

I BUILT THE TONK! (Frantic)
https://m.youtube.com/watch?v=vl1a8ws-aJo

The Tonk is a basic but still works tank. It has a 76 millimeter Auto Cannon. The Tonk is designed around the comet.

The Tonk has a single track, a double track with a hole in the middle, and no track at all. The Tonk has a hole in the exhaust.

The Tonk has a Commander's cupola. The Commander's cupola is slotted directly on the top in the middle and is thinned down.

The Tonk has a driver's view. The driver's view is directly on the top of the Tonk.

The Tonk has a fuel capacity of 50. The Tonk has a transmission. The Tonk has an engine.

Unironically, The TONK might be a great choice for modern drone vs. tank warfare. As it is lightweight, but armored it can move very fast (limited fuel capacity / limited ammo capacity), is cheaper to manufacture is a one-man vehicle. So field unit loses are about the same, but at a higher cost. Essentially, it's a armored fast grenade, bazooka launcher with limited distance but very fast travel over bad terrain. Ideally you'd have a separate refueler and a separate weapons storage platform which would require a Bluetooth or encrypted chat system to initiate reloads as a imposter would have easy access to blow up the Tonk Army.

Lots of crazy dudes with fast low yield weapons emissions overwhelming genuine slow tanks on a battlefield (attrition by cheapness) meaning a field of 10 genuine tanks vs. 30 Tonks should be like trying to swat skittish flies. Meanwhile you have 30 TONK bazooka yield guns taking potshots and fleeing faster than they can be target locked. A 6 to 8 man crew inside the genuine tanks means an 80 man death toll plus multiple millions of dollars spent. 30 Tonks means maybe 2 million lost for 30 Tonks, and 30 dead Tonk operators.

Tonks wouldn't last against this.

Infinite is way more than "a lot". If you used every atom in the universe to encode an additional power to raise the total number of atoms in the universe to, you would still be closer to 1 than infinity. In fact you could repeat it for an endless number of universes and you still wouldn't be any closer to infinity because infinity is defined to be above any number that can be conceptualized.
You can never reach infinity because it's qualitatively above not quantitatively.
Throughout history infinity is virtually never invoked in the way we understand it nowadays, they always simply mean something to be endless which is closer to the definition of a limit. The actual infinity is a concept that came much later despite what people think.

>>16708557
Yes, infinity isn't a number or object, it's an unending process with the basic metaphor being counting the natural numbers (1...2...3...) This also goes for infinitescimals.

The Fundamental Theorem of Calculus isn't just a mathematical theorem, it describes the fundamental nature of all processes, including time itself. We experience time in two interdependent and mutually necessary perspectives: instantaneous change in the ever-changing flux of a singular experiential moment (Differentiation, the mode of present sense-experience) and cumulative change over time (Integration, the mode of narrative.)

Someone is asking real human beings for input on a question. As opposed to you know, asking a mindless chatbot.

Maybe smug gatekeeping nerds on the internet attacking anyone who dares to ask a curious question is part of the reason why people are driven to chatbots?

lel, semi-related story:
the one time I asked a (carefully written) question on StackOverflow, the product owner of the API I was asking about responded directly to my question and I check-marked his correct and straightforward answer. Good experience, 5/5

For sure though, the comments on Questions with a lot of visibility/points were insufferable sometimes
Their real downfall in my opinion, is still not allowing Questions to ever be asked again just cause someone already asked a similar thing 12 years ago
