This is misleading. There is no associative property to speak of, because series are not actually infinite sums, even though they are often presented with historically obsolete notation that visually makes it look like they are infinite sums. They are not an arithmetic function applied to infinitely many terms. Rather, what you have is a sequence, to which you apply a linear transformation, and then you evaluate the limit of that transformation. The transformation involves adding the first n terms of the sequence consecutively, to make another sequence, so in this regard, it is *related* to the topic of sums, but the actual composite operation being carried out is not summation, and so this is why it makes no sense to bring up associativity into the discussion. This is why it is harmful for schools to continue teaching the subject of series as being infinite sums.

Another way to think of it is in terms of countable and uncountable sets and, more precisely, their cardinals. Basically, all countable sets have cardinal omega, while uncountable sets (like (0,1) or R) have cardinal c (continuum). Now, the way I like to phrase it is that "c swallows omega" as in, adding a countable set to an uncountable set would still give an uncountable set. So, since [0,1) is just (0,1) with one element added, {0}, the cardinal of [0,1) is still c. Note: I did say that uncountable sets have cardinal c, but that's only true for sets like R. You could get sets of higher cardinal by taking the set of subsets of an uncountable set. Sorry for using the word "set" so much

John Gabriel New Calculus

Compressibility is a function of information entropy. One can show by the pigeon hole principle, that for any compression algorithm, if there exists a collection of symbols(a file, including pictures) that can be represented with fewer symbols(its size is reduced), there has to exist a collection of symbols(another file), that can only represented using more symbols using that same compression algorithm. So it is mathematically impossible to represent every file possible, each with fewer symbols. You can see this phenomena in action by trying to compress a zip file twice.

I can only store 9 pixels per picture, and only one picture :,(

Assuming the images are stored as a binary string of pixels with no extra data such as dimensions or camera data, any compression algorithm (that isn’t just the program used to make the images) will only add size.

@@nullnull805 That assumes a lossless compression I guess.

@@dhay3982 Lossy compression would result in many images having duplicates stored. Thus, you violated the condition of storing every possible (digital) image. However, I suspect that the plans for how to build a free-energy machine, would still be readable, so does it really matter?

Yes, this is sound and a nice argument. I also present a different version where you take the function f: x-> x/2 +1/4. This function is one-to-one for both [0,1) to (0,1) and (0,1) to [0,1) which implies (0,1) >= [0,1) >= (0,1). Then you already h ave(0,1) = [0,1).

I think the beauty of the proof in the video is that it can be used to show something more general: the union of a finite set and an uncountably infinite set is still uncountably infinite. Outline of proof: 1) Realize the interval (0,1) is uncountably infinite and so we really just need a bijective mapping from (0,1) to (0,1) U {finite set with n elements} 2) In this video Zach mapped 1/2 to 1/4, 1/4 to 1/8, 1/8 to 1/16, etc. These are the reciprocals of powers of two. Notice that 2 is a prime number. You could do the same with powers of 3,5,7,etc. 3) Repeat step 2 n times. You will need n primes. 4) fill in the holes at 1/2,1/3,1/5,...1/p_n with the finite set that has n elements 5) you can verify yourself that this is indeed a bijection. The reason you must have reciprocals of prime powers is to keep it 1 to 1.

It's not trivial that it works. You need to prove that if A is smaller or equally large as B, and B is smaller or equally large as A, then A and B are the same size. If you think that's obvious, then I challenge you to prove it yourself. Just to clarify, when I say A and B are the same size, I mean that there's a function from A to B that is one-to-one and onto. When I say that A is smaller or equally large as B, I mean that there's a function from A to B that is one-to-one (but not necessarily onto). This is always the case when A is a subset of B, just map A to itself.

ElzearYoung It is a contradiction for one to be smaller than the other. If the system is consistent, then a contradiction cannot occur in it. The system is consistent. A = B Do you want another proof that uses a different line of reasoning?

@@funkyflames7430 That isn't actually a proof. You are implicitly assuming that our notion of "being at most as large as" being defined by there being a one-to-one map and "being as large as" being defined by there being a map that is one-to-one and onto behaves like a "normal" ordering, but that is actually the non-trivial part of what you have to prove. Given our definition of size, A not being the same size as B does not necessarily imply that either A is smaller than B, or B is smaller that A (in fact, this being the case is, actually, equivalent to the axiom of choice - if we assume that the axiom of choice is false, there are two sets A and B, such that they are not of the same size, and neither or the two is smaller than the other. Unlike our example, though, neither of those sets is going to be at most as large as the other, either). To prove that A being at most as large as B and B being at most as large A implies them being equally large, what you have to do is show that, given some map A to B that is one-to-one, and another map B to A that is one-to-one, you can construct a map A to B that is both one-to-one and onto (this is known as the Schröder-Bernstein theorem).

*Size Matters* _gets a Facebook Messenger ad_

Good observation

and by the original logic of the question, something would have to be infinite. the pixels, the pictures, the PC, or the storage.

You don't even need pictures with infinite number of pixels. Finite but unlimited size still requires infinite storage. Also, you can't actually, even in principle, store all 12 megapixel images, since that is more images than the observable universe has atoms.

Well, a thought process on this shows that there can be infinite pictures and that the video is wrong, in the same way that some infinities are uncountable. Say you have a picture of a forest. Sure. You can then have a picture of me, looking at the computer screen of said forest. To expand further you can have another picture, of another picture of me, looking at another picture of me, looking at a forest. But matter how many times you add on a single picture of me, you can always have another picture of me looking at the previous picture. You can even have more split infinities in top of this by simply adding another picture into the mix. A picture of me, and then a picture of me looking at a monkey, and on a monitor beside a picture of me looking at a forest. You could even nest the previous infinite sequence of me looking at a forest, within the new looking at a picture of a monkey sequence, which is infinite itself. Even with limitations on megapixel size, you can have even more pictures added now, of zooming in to the me looking at pictures of me sequence, like a fractal, spanning down towards infinity and never ending. On top of this, you could have a sequence that includes "every possible image" but then feasibly conceptualize a new image on top of that, of you, looking at a monitor that shows every possible image on it. No matter what, there will always be some other sequence of infinite images that you can create.

How did you conclude the universe is not infinite?

Feelit Believeit If the universe is infinite you could theoretically have an finite amount of matter in the universe. You could measure the acceleration of the universe and calculate the matter. But tbf there are few assumptions to this calculation that could be false. But my point is that theoretically you could have a infinite universe with finite matter.

@@Flammewar yet you could only have an infinite amount of matter with an infinite universe, and you could have a computer of arbitrarily large size with infinite matter

Fun fact: It's trivial to make a computer that could look up any image of size N pixels. You just make a program that coverts an input integer into a different image of that size. 😅 All the data is stored in the lookup addresses that way, but you'd need that many bits in the lookup address anyway, even if you did have a drive containing every possible image.

Feelit Believeit Ok but this isn’t the question. He didn’t ask for arbitrarily big computer instead he wanted a computer which could store every existing picture. For this problem you need a fixed amount of matter, which could be to big to exist in an universe.

But also a lot of not quite correct proofs. See this one: en.m.wikipedia.org/wiki/The_Library_of_Babel Yes, it does contain every truth, but finding it isn’t made any easier.

@@rushunnhfernandes The Cantor set and Sierpiński gasket (aka triangle, aka sieve) are fractals, mathematical objects which (in a very well-defined way) have a non-integral dimension. Specifically, the Cantor set has dimension ln 2/ln 3 and the Sierpiński gasket has dimension ln 3/ln 2. As for why, here's the reasoning. If we double the scale of a one-dimensional object, its content doubles; for a two-dimensional object, it quadruples, and so forth. The exponent is the object's dimensionality. If we triple the scale of the Cantor set, its content doubles; conversely, if we double the scale of the Sierpiński gasket, its content triples. (This is where images would be soooooo useful.) As for what they look like, well, you'll just need to fire up a search engine. The very concept of non-integral dimensionality is highly counterintuitive, even nonsensical at first, so give yourself time to digest it if this is your first encounter with it.

@@tomkerruish2982 Another analogous way to visualize this is by estimating the distance of a territories coastal line. Depending on how close or far away you are (zoomed in or zoomed out) AND the unit of measure you are using (inches, feet, yards, meters, miles, kilometers, etc...) You will end up with completely different and varying values. Yet the actual size of the coastal line is practically finite (not exactly because it does change over time due to erosion, wind, etc.) but is finite in a given exact moment or frame of time. Yet the dimensionality of these coastal borders has a fractal-like pattern that is not an integer polynomial, they are fractional polynomials. For example, they are not x^2, x^3, ... x^n. They are closer to x^1/2, x^1/3, ..., x^m/n (n != 0).

@@rushunnhfernandes Those shapes are self repeating fractals, there is a way in which fractals can be considered to have a different dimension number than your standard whole numbers. Those two numbers for those two fractals are reciprocals with each other.

interesting thought, but i thought i'd point out two very important distinctions that can be made. firstly, time has only ever been observed to flow in one dimension, whereas this grid exists in two dimensions. secondly, time is assumed by most well-established theories to exist on a continuum, and the numbers talked about in the video are on a discrete grid. still, interesting idea, and in my opinion you can never be too philosophical about maths!

Natural numbers are of the size "aleph-zero" which is the smallest. This is called countable infinity. Real numbers are "aleph-1" which is even higher. You can not biject real numbers to natural numbers. This is uncountable infinity. Let me introduce terminology: The power set of a set A is the set of all possible subsets of A. For example the power set of {1,2,3} would be:{ {1,2,3} , {1,2}, {1,3}, {2,3}, {1}, {2}, {3}, {} } which has 8 elements. The power set of natural numbers is also "aleph-1". The power set of real numbers is "aleph-2" The power set of a set that has the size of "aleph-2" has a size of "aleph-3". So infinities can be as big as we want. The real question is how to interpret anything higher than "aleph-1". We don't even know for sure if there is anything between "aleph-0" and "aleph-1"! That is, a type of infinity that is smaller than the reals but bigger than natural numbers. This is called the continuum hypothesis and is an unsolved problem.

The real numbers are strictly bigger than the integers. Every good broad-audience math channel on youtube has made a video about this: Numberphile: kzfaq.info/get/bejne/m9Kmgr2elcqYeGQ.html Vihart: kzfaq.info/get/bejne/aJl5aKqEmbDNdJs.html Infinite Series: kzfaq.info/get/bejne/n52TZdSrnNmzYH0.html

Unless you have had a surprising leap of intuition, or reasoning, or have encountered all of this before, it's not unreasonable that you would assume, or at least intuit, the infinite nature of the sets would allow creating a one-to-one onto mapping between any two infinite sets. Basically, infinity weirds everything it touches.

This literally has 0 applications stay in school kid

The applications of certain mathematics lessons can be varied, and some of them can't be made apparent to you because you don't have enough knowledge of mathematics to understand the application (take, for example, "imaginary" numbers, which I am constantly told make absolutely no sense by people, mostly because they get hung up on the word "imaginary" and won't let go). That doesn't mean you can't learn the rules and use the rules for simpler things even though you don't fully understand why the rules are that way or what their grander applications are. If the advancement of human knowledge REQUIRED that people always knew what the "applications" were beforehand or even at the same time, we would never learn new things and never have access to new applications. Nothing would develop. You are thinking about learning in a completely backwards way. It may make sense to you to do that, but it is ultimately going to get in your way.

Numbers

Not exactly true... in cartesian plotting yes this could be determined, however, if we expand this to the complex numbers and plot them in the complex plane using polar coordinates... you can in theory map every real. An example of this is taking the roots of a quadratic... when we map them in cartesian space where the parabola is either above the x-axis or has one point tangent to the x-axis we end up with either 1 or 2 imaginary or complex roots and we can not graph or plot them. However, if we expand the cartesian x-y plane to include the complex plane we can then map every root.

@@skilz8098 The complex plane is larger than the real plane. In fact |ℂ| = |ℝ²|. In other words, the cardinality of the complex plane equals the cardinality of the real line squared. We don't know any uncomputable number because we can't compute it. Therefore we don't have a representation for it nor can we know its value. You're proposing an algorithm, in other words, a way to compute the number. Therefore you're still operating within the set of computable numbers, not the real numbers.

@@RealLifeKyurem I wasn't exactly suggesting that... basically just because we don't know how to compute it, doesn't mean that it can't be!

skilz8098 There are uncomputable numbers, and it’s not a matter of knowing the algorithm. Let ψ be an uncomputable number. By DEFINITION, there is no formula, mapping, nor algorithm that can tell us what it’s value is. If there is an algorithm, even an unknown one, it’s not an uncomputable number anymore.

@@RealLifeKyurem Actually, there are as many complex numbers as there are real numbers in a set theoretic sense, though it requires first showing |ℝxℝ|=|ℝ|. A clever way of doing that is this. Since the cardinality of ℝ = |(0,1)| = |(0,1]|, we can freely play with decimals without whole numbers in front. For a decimal expansion of two numbers x and y ( (x,y) an element of (0,1] x (0,1]), there are nonzero numbers by which we can segment each decimal into blocks. Now, for each real in (0,1], there is a nonterminating decimal expansion (for instance, 0.1 can be represented as 0.0999...). Then, segment each decimal based on when the ending is nonzero. So, for say 0.3510031903..., we get the blocks 3 5 1 003 1 9 03. And for say 0.29031053006... we get 2 9 03 1 05 3 006. Then, doing this for x and y, we can form a new number in (0,1] as follows-start with the first block of x, then the first block of y, then continuing on to the second. We get the decimal .325910300311059303006... By this process, one can decompose by this alternating method each number in (0,1] as a block pair and form two block pairs that correspond to (x,y) in (0,1] x (0,1], so it is one to one and onto.

Actually you can. You see the ambiguity is in the "..." we use at the end of an infinite sum. It does not do justice to associativity which is the true problem of Riemann Rearrangement theorem. In sigma notation it is more clear what is happening and you can choose to construct anything. Remember that infinite sums are defined as limits of finite partial sums.

Hassan Akhtar That last sentence is often what clears up infinity for most. We have to define infinity and explain what we mean by it so that people can actually understand its implications.

Here is something unrelated to the rearrangement theorem but relevant to associativity and infinite sums: What is 1 - 1 + 1 - 1 + 1 - 1 + ... ? A common beginner answer is "it depends on where you put brackets". (1-1) + (1-1) +... = 0 (1) + (-1+1) + (-1+1) +... = 1 (1) + (-1) + (1) + (-1) +... = NOT EXISTS Of course we standardly assume the answer is does not exist because we think the partial sums are defined term by term. In reality, sigma notation removes ambiguity and all 3 of those results are valid as long as you define your sequence. That is how we deal with associativity. For example what if you want 1-1+1-1+.. to be equal to 1? Let a_1 = 1, let a_n = (-1+1) for n>=2. Then the infinite sum from n=1 to n=infinity of a_n is indeed 1 (again think of limits of partial sums). This is effectively like putting brackets like I did above!

Hassan Akhtar Keep on teaching and preaching the word of math! I love it

It is valid. For conditionally convergent series you have one sum for each ordering of the terms, and for absolutely convergent you have exactly one sum for any ordering.
