Interesting things happen when you allow negative numbers. There is exactly one cycle of Length 1: 0 Length 2: -2 -1 Length 3: 4 2 1 Length* 4: -2 -1 -2 -1 Length 5: -20 -10 -5 -14 -7 There is no reason why this uniqueness should continue, as the number of cases to consider keeps increasing. But are there lengths which have no cycle at all? *) That's actually a double cover of the Length 2 cycle, there is no other way to make a length 4 cycle. Might be better to say there is no length 4 cycle at all.

The story referenced features a boy born with a great golden screw in his belly. His parents don't understand it, so one day he goes out into the world, asking at the big towns, the famous hospitals, the great halls of learning, the many monasteries. Still, not a single person can tell him what it is or why he has it. Finally, he comes before the king, and, prostrating himself before his infinite wisdom he asks: can you explain this golden screw? The old king is thoughtful, until, with reverence, he reaches into a nearby gilt cabinet, and reveals a great golden screwdriver. He places it against the boy, and it fits the screw perfectly. The boy is overcome by excitement. The king turns the screw once. Nothing happens. He turns it twice. Still nothing. He turns the screw one last time. And his ass falls off. The riddle mentioned at the start of the video came when the dad asked what the story meant, and, being nonsense, it didn't, that's the whole bit. Of course, in the novel as a whole this capacity to seriously apply ones mind to things that are impossible to understand is a very important theme

When I was a sophomore in high school a handful of years ago, I thought I had solved the Collatz conjecture at three in the morning, called all my friends, and woke up the next morning to realize I was completely wrong.

You indeed made a mistake. You will notice it when you try to apply this technique to some infinite sequences. For example, the arithmetic sequence a(n) = 2n+5, or a(n) = 2*(-1)^n+3. You wrongly assume that there is some "last" number a(inf) and then show that it is impossible to construct an analogous Diophantine equation for it. It does not follow from this that this sequence is not infinite.

@@HighlyEntropicMind In short, because what you're thinking of isn't a sequence equation. Your equations determine two variables that mark the beginning and end of the sequence/constellation. When a constellation is finite, the beginning and the end determine the whole of it. That's why you can call such an equation the "constellation equation". But the non-existence of the equation unfortunately does not prove the non-existence of the constellation. Problems with constructing the "infinite constellation equation" may suggest that there is no such equation (another thing is that you cannot immediately rule out that there exist some other secret technique that allows you to create such an equation). In this case, you are right - there is no such equation, because there is no number that could be called the end of such a constellation.

@@HighlyEntropicMind Suppose that the sequence looked like a_n = a_0 + n. (I know this doesn't work but if I could find you one that worked I'd have proved the conjecture false so bear with me.) In that case, you wouldn't be able to calculate a value for a_inf, because you'd just get infinity. And that makes sense, a_inf is not a real thing, and it's not part of the sequence. Like here's a question: with the infinite sequence I provided, what is a_inf mod 2? Well, the parity of a_n alternates between 0 and 1 so the limit of a_n mod 2 is undefined. You should also consider that the existence of an expressible equation at all is unlikely to exist if the conjecture is false because of an infinite constellation. If the infinite constellation repeated, then you could convert it into a cyclic constellation, which could result in a cycle of numbers as well. But if the infinite constellation doesn't repeat, then trying to find a closed form for the nth term seems like trying to find a closed form for the nth digit of pi.

So instead of trying to answer if you are a crackpot or not it would be better to find somebody else and ask them what they think about it. This is also the essence of supervision and peer review. One really can't approach their own writing in the way you read what other people wrote this is why you really need somebody else to go over it.

I'm only 13 minutes into the video but I already like it heartily beacuse it seizes what most other math KZread videos, however comprehensible and well-made, fail to portray: the feeling of *actually* doing math. It's really all about the exploration, testing and trying out various ideas that may or may not eventually work out at all, about giving things silly and/or beautiful names in the process just for aesthetics and simply to have fun, about looking at the examples of certain behaviours first and only then trying to formalize them, as to find out whether the patterns you think are true do indeed hold and if they tell you something about the problem you're working on... or a completely different one. This is what I'm doing math for, this is why I love it. Huge props to you for being able to share this feeling with the general audience instead of trying to make yourself look perfect and your reasoning polished to avoid criticism. As the community of mathematicians, we should generally accept that making mistakes is a natural part of what we do, and we shall not hesitate to share our attempts, to correct and to be corrected. And you also helped me to look at the great unsolved problems of mathematics form a different angle. I never really considered actually trying to work on them because I'd never put in words this philosophy of "being able to learn from them forever". I had that feeling inside of me, but it was contradicted by the steel logic of "if you most probably won't be able to solve them, why even bother?" Now I can see clearly that this is not about finding the actual solution, but about what you can learn while looking for one, so now I fell completely free to give it a try. Thank you for that!

Thank you so much for this comment

I like the emphasis on having intellectual humility, while still encouraging the process because it's what leads to learning. That's really the only reason I've ever fiddled with the conjecture. Here's what I came up with: If we suppose a strong induction proof might work on the Collatz conjecture, then we only need to look for starting numbers such that their sequence that follows will eventually dip below the starting number. Thus, it doesn't matter how fast we proceed through the sequence, so let's define an accelerated collatz function. If n is even, then n=(2^k)*m for odd m and some k. If n is odd, then n=(2^k)*m-1 for odd m and some k. Then the accelerated collatz function is given as follows: f(2^k*m)=m and f(2^k*m-1)=3^k*m-1. This function has some nice properties, like how k is the number of iterations of the standard collatz function (which often immediately divides 3n+1 by 2, since it is guaranteed to be even), and how f(even)=odd and f(odd)=even. This gets the same result that you got (namely, a method of generating our choice of sequence) but I think it's a bit simpler in my opinion.

@JM-us3fr

10 ай бұрын

Addendum: I should mention an additional nice property. The values of f(even) will contain the limit inferior, so if it does dip below the initial seed, then it will appear as f(even) for some even term in the sequence.

@JM-us3fr

10 ай бұрын

Oh another thing: if you view k sort of like a random variable (not really because N is countable, so has no uniform probability), then k would have expected value 2 given the density of even numbers. Thus, on average we can expect even numbers to scale down by a factor of 4, and odd numbers to scale up by a factor of about 9/4. So on two iterations, we can expect a net scaling of 9/16, which will decrease on average. So it’s pretty clear that the collatz conjecture should be true for almost all n.

@@HighlyEntropicMind Interesting I actually tried to get somewhere with this and just got as far as figuring out that an equation for any starting point n to the next point f(n) would be "f(n)=(5n/2+1)(n mod 2) + n/2" which I found by adding together the equations "(3n+1)(n mod 2)" and "(n/2)(n mod 2 + 1) - n(n mod 2)". The reason I bring this up at all is that the 5n+1 looks very similar to my 5n/2+1. Example to show it works: f(1) = (5/2 + 1)(1 mod 2) + 1/2 = 8/2 = 4, f(4) = (4/2 + 1)(4 mod 2) + 4/2 = 4/2 = 2 etc. The reason it works is just because I used the modulus function to get the value of 3n+1 to be 0 when the number is even and used it to make the n/2 term 0 when n is odd.

@@falnica but if the algo can produce sequences that are partially collatz, but then deviate (like example given above), we have to ask what constraint on b produces valid collatz sequences, not just integers, as we see that anything can happen. (i.e. some rational input b might produce a sequence of integers that are not collatz nodes, but you would not know unless you check.) So this algo may or may not yield all constellations, and may yield infinite collatz-disguised whatever. The behavior hinges on how we might further parameterize b to obtain desired output of algo. (Is that even possible?) It does seem true from video that integer b yields a valid collatz sequence which is also a constellation of specified sequence. This is probably useful to identify this family of constellations and work from there.

So glad I found your channel, first video of many for me to dive into, thanks for the hard work!

I love your videos ❤ Thanks for making these amazing masterpieces

Well you have proven that some specific sequences of tiles must start further and further away from 0 the longer they get, so those for sure cannot be present in a cycle because a0 cannot stay bounded, but the rest doesn't seem to ask the actual question (like sure you can find a number that's limit of an infinite constellation, but that's not necessarily the only possible new cycle)

when I tackled it I ended up going a different direction: I saw that nodes are either 4 mod 18 , 10 mod 18 , or 16 mod 18 , and they go in a cycle in the /2 path: 10->16->4->10 , 10 nodes are the solutions to 3x brahces, aka "dead" branches, 4 nodes are the solutions to when a node needs to be divided by 4 before needing to be multiplied by 3, and 16 nodes are the solutions to when a node needs to be divided by just 2 before needing to be multiplied by 3... but I had no idea what I was doing and ended up just going in circles as a layman

Really excellent video! I just discovered your channel and am loving your energy and ideas. Your introduction motivated me to pursue solutions and/or non math pursuits which may, at first, appear impossible

This video is amazing! You really showed the joy and exicetment math brings to the ones who study it. Also, you inspired me to give Number theory a shot (i'm writing this as i try to read further into Vinogradov's book) so thank you for that too!

Interesting video. Fer's conjecture and the super awesome tiles seem like great ideas! Fer's conjecture could be even stronger: if the distance between nodes is 2, it's only when the last number is odd (the Lannister tile), although then it's a bit wordy haha. About infinite constellations: on 30:38 you assume that the sequences alpha(m) and beta(m) have to converge to some alpha and beta. I fail to see why that has to be the case.. Also, on 32:02, you say the potential a_inf is "clearly" not a part of the Collatz tree, but why not? Could it not connect to 1 through a different path? Finally, at 32:50, there is a problem with the exponent trick, because it essentially says that an infinite product of (3/2)s, (3/4)s and (1/4)s cannot converge. This is clearly false, as a product of just (1/4)s and (3/4)s tends to zero. (This obviously doesn't produce a valid infinite constellation, this is just a counterpoint to the exponent trick). I think the problem here is as follows: once you rewrite it as an exponent, the product becomes a sum, and then you rearrange the terms in the sum, grouping all the 3s (ln3s) together and all the 1/2s (-ln2s) together. Rearranging an infinite sum only produces the same result if it converges absolutely, which this one clearly doesn't. One more thing: on 42:39, isn't GCD(2^w, -3^r) = 1? Oh, and on the problem you've encountered in the end: it seems like your algorithm doesn't find all solutions to the diophantine equation, just one family of it. Otherwise you would get all the integer solutions by substituting integer values for b. I am not well-versed in diophantine equations myself, but that seems to be the problem? Thanks for the video!

I love the way these ideas are presented

IMO it's fine to call the nodes that have multiple connections anything you choose, but if you want to differentiate then you could refer to them as something such as Converging Node, as they are the integers where sequences converge.

Really enjoyed video. Incredibly brave to toss your ideas out for scrutiny. Value for non-mathematians (like me) are your thought processes and strategies. ...These types of problems can be addictive even when every idea hits a dead-end. :).

What freaks me out is that I made a disturbingly similar mistake at solving the same problem about a few days before this video aired. My "proof" never pretended to prove the full conjecture, but only that there wouldn't be any cycle other than those already known... and of course it was wrong. I had a result quite similar to what you get at 42:38 and for some reason believed it meant solutions would correspond to 2^a-3^b = 1 or -1. Still, I was able to prove a similar result than your "constellation", which has the consequence of proving that there can't be a periodic constellation that doesn't cycle. (so constellation that doesn't cycle must be aperiodic if they exist). Then I found out some guy already had proven this for their thesis (but I am still proud my proof can fit on two pages, is relatively easy to understand, and works for non-collatz sequences as long as they share some of its properties) I am currently trying to write a paper about it (I probably will leave it as a pre-print, but I can send you the link to it once it starts looking like something and I have an English translation)

Man I have been working on and off with an unsolved problem for years. Took a break but this has really inspired me. Love the king killer reference

Instead of the collatz conjecture, let's look at f(n) = n + 1 instead. This obviously has infinite sequences. I'll try to follow along and apply your reasoning to this. If the conclusion is reached that no infinite sequences exist then that's a problem. 12:06 If n = a, we'll call it a Unit. (So just every number) 12:55 The Unit Tile is pretty straightforward. It can just connect to another Unit Tile 13:37 We can place Unit Tiles together, for example UUU or UUUU 15:08 For the Unit it would be n + 1 = s, which has solutions n = a and s = a + 1. So that's how you could find any Unit. 20:43 For the Unit it would be a_m = a_0 + m, which has solutions a_0 = b and a_m = b + m. So that's how you could find any constellation. 24:29 We can skip this, because we only have one type of tile. We can already find any constellation. No need to do threading. 31:07 You're saying that these constants should both converge to something, in order for an infinite sequence to exists. But in our case, by looking at the equation a_m = a_0 + m we can see that Alpha does converge to 1, which is good, but Beta does not converge because it is equal to m and so will diverge as m increases. That seems like a contradiction. But maybe I'm misunderstanding. I'll admit I'm not THAT good at mathematics.

@jebbush3130

TLDR: I think the statement at 31:05 is incorrect and that this is why the proof is wrong. The claim is made that Alpha and Beta should converge, in order for an infinite sequence to exist. A counter-example to this is the function f(n) = n + 1. Here the formula for any constellation would be a_m = a_0 + m. So here Beta (equal to m) does not converge as m increases, and yet infinite sequences do exist, which contradicts the original claim.

Maybe I don't understand the ending, but I think that It makes sense that you can extend to the rational numbers, because for every rational number q, the numbers q/2 and 3q+1 are also rational, which means that you can kind of make what I imagine as a 'web' of rational numbers, where every number q has arrows that points to q/2 and 3q+1, and has arrows that point to it from 2q and (q-1)/3. The tree that you describe is sparser because it restricts it to only certain kinds of constellations, but I think the idea still applies. Checking the parity of rational numbers isn't really possible though.

Obviously, there are fractions that if you multiple them by 3 and add 1, enough times, you'll get an integer, but the Collatz Conjecture requires the number to be even or odd. A fraction is neither. I guess if you just checked to see if a number was even or not even, fractions would work.

Problems probably start happening around 3^34 because that's around 2^53. There are 53 bits of precision in a 64-bit float

Thoroughly entertaining.....it's been a while since I've contributed to my own channel, and I would love to learn Manim and give my own pet problem an "honest attempt" youtube video for the next SoME...this comment is to put that out into the universe so I actually have to do it! Thanks for the knowledge and entertainment

Perfect intro and theme, great video!

Don't doubt yourself my man. This is really interesting and the jokes well timed lol

I didn't think I could, watch a 1 hr video after not sleeping the night, at 5 in the morning. But I am invested. I surely didn't understand some stuff, but I got hooked on a lot of stuff you showcased. The thing at the end is also so great!!!

You won me in the first few seconds. Love the reference to A Wise Man's Fear.

love your energy -- great video

The math is way over my head but I give the video an A+ for the methodology. Mistake or not, it's a great teaching tool on working through problems.

A new perspective is always welcome.

I love this, really enjoyed going on the journey with you

In the beginning of the conclusion part i imagine some enlightened monk sitting on a stone under some old tree, infront of his class of diciples, lecturing and getting sidetracked to some weird stuff and ending with "...i could be right, and i could be wrong"

Randomly, at 11:25 your graph with k = 3 and (2k-1)/3 has a typo where it says 5/5 instead of 5/3 :)

It seems like when you compose diophantine equations you are only considering solutions that make both original equations integers. You also need the solutions where the first outputs a fraction but the second gets back to being an integer.

your videos are so good and I love ur character, you seem like a really nice guy

Top 10 things I wish someone said to me in real life

The number -2 is a Stark node that's followed by infinitely many Stark nodes, all equal to -2.

Great video. By the way, Diophantus actually used lots of rational numbers, too, but for some reason whoever called the equations Diophantus equations required the solutions to be integers.

Still, it's very interesting

The problem is that if there is no counter-example, then proving that there is none is extremely hard and requires that advanced math that only the most learned know. You cannot just "come up with a solution" if the solution is a mathematical proof that no counter-example exists. You need a huge amount of knowledge in math in order to come up with and correctly express such a proof. Plus, of course, finding the proof is extraordinarily difficult.

I dont have enough knowledge to explain why but what you notice with the super awesome tree really strongly makes me think about 10-adic numbers, if I have the energy I should at least look for the 10-adic numbers corresponding to your rational values for b and look for patterns

Great video. Congratulations!

Since you mentioned Scott Aaronson, would you be willing give give a "for amateurs" explanation of his Collatz conjecture work? It sounds super interesting. Somehow it reformulates it in terms of rewriting rules on a string of characters (like your sequence letters?), and culminates in the claim that if matrices with certain properties exist, it proves the conjecture? I currently don't understand it, and its a shame there isn't a good overview of this more current research on youtube.

There are MANY other videos explaining the Collatz Conjecture in a way that everyone can understand, I mentioned the one from Veritasium in the video, but there's also this one from Numberphile: kzread.info/dash/bejne/Z6F60rh9oK6-Z5M.html&ab_channel=Numberphile

I gave it a go and tried to approach it by finding a loop. Because even numbers just half down to some odd number, I decided to try to find some way to get to each odd and ignore the even numbers which might make such a process very lengthy as the numbers grow. To do this I invented a new operation which I called factor manipulation. When you manipulate the factor of some number (represented by fm_n) it returns the list of prime factors in descending order, with each factor labeled as f_a with a being the order that the factor is in. You can refer to these factors using the operation, and that means you can manipulate each individual factor in an equation however you want. Basically, fm_n(f_a+3) would return the a’th factor of n and add three to it. You can mention more than one factor, multiply factors, and more. The goal was to try to define what happens to the prime factors in a number when the number goes through an addition (the +1 in the conjecture) but unfortunately I don’t have any coding skills, so I’m not able to create a calculator to perform math with my operation. I had fun though! It’s really interesting to see how different people go about solving the same problem.

Very thought provoking video, and thank you for uploading a very nice writeup. Regarding the notion that this generalizes the Collatz in a similar way to how the gamma function generalizes the factorial - I think they are quite different, and that the differences are illuminating. This generalization is not one function, but instead a family of SuperAwesome functions indexed by a streak and a position therein, e.g. These can be viewed as rational (and indeed linear) functions, e.g. S0(a) = 2a+1, S^m0(a)=2^ma+2^m-1, while S1(a) = 3a+2 and S^m[m](a) = 3^ma + 3^m - 1. As all the tiles correspond ti rational linear functions, any (finite**) iteration of then will be linear with rational coefficients and so can be written SuperAwesome0(b) = (u/v) + (x/y) b. Integer are whenever b=(y/x)(k - v/u). Similarly there is SuperAwesome[n](b) = (t/w)+(c/d)b integer when b=(d/c)(k - t/w). So a streak that starts and ends at an integer for a specific streak are given by the intersection of the integer spectra of the first and last SuperAwesome functions for that streak. A full Collatz solution would require the intersection if the spectra of all m+1 (assuming m tiles) SuperAwesome functions. If the rational coefficients can be related to the the streak sequence, then it should be possible to bound what fraction of integral solutions are actually lost when adding one additional step to the streak. Establishing that this proportion is bounded above 0 (or even log(n)/n) could [convincingly?] show that Collatz solutions must vanish. A similar approach could be taken for cycles as well.

Just a tiny comment, but huge respect for citing the AI art and prompts in the videos. It's in keeping with my university's guidelines on using AI works, and I think it's a good precedent.

There were no images of Diophantus I could use, and I always cite everything

Finally, a near-miss that won't be named after Parker.

Great food for thought

This raises the question 10 gives the sequence 10->5->16->8->4->2->1 in the Collatz Tree since the Collatz Tree is a subset of the Super Awesome tree, 10 should also give the same sequence in the Super Awesome Tree. However, 10 gives another sequence, namely 10->16->13->20.5->31.75->48.625->... That means in the Super Awesome Tree, a number can split into two paths, which makes the Super Awesome Tree not a tree anymore.

So I guess my next question would be is there a nice formula for all b that result in integer sequences? I don't think the super awesome tree is quite right unless you generalise the decision rule from divisible by 2 to something else, but without some thought I can't think of a generalisation that guarantees that exactly one of the rules applies for any given rational number.

If we extend the conjecture to just all rationals rather than something like all reals, we could differentiate the numbers by the properties of the numerator or denominator in the number's reduced form. Eg. apply the rule based on if the reduced-form numerator of the given number is even or odd.

When you were playing with b as a fraction, I noticed you only got integers when the denominator is 2^m 3^n -- only has prime factors 2 and 3. Since powers of 2,3 already came up, this may be a hint.

The nodes are integers, but are the intermediate numbers in the branches integers?

the way i cheered when you mentioned set theory

I think it's fun simply making the tree of the sequences myself and finding patterns that makes growing it slightly easier Such as the pretty trivial fact that any power of 2 will rush down to 1 as quickly as possible

a solution for a loop of super awesome tiles would be a solution for a infinite string of super awesome tiles but first we must define some thing that call a cfl of the loop of super awesome tiles it would be the loop but cut off when it repeat; the infinite string of super awesome tiles would be the clf repeat infinitely.

This is the first true extension of the Collatz conjecture I've seen (47:24) when looking on Wikipedia or other Collatz videos (including yours) they usually show fractals that are made through the continuation of the Collatz conjecture. but they have always been "artificially" extended, I don't have enough characters to explain, but the extensions aren't derived from the consequences of the Collatz conjecture. I feel like someone needs to re-do those fractals with these new values you have found... assuming it can be proven that it truly is an extension, by (probably) showing that you can't just get any number through this method. of course I'm just an amateur, so I don't know that much. I'm really excited the new are that hopefully will be created by this new discovery.

I know what you mean. This extension of the Collatz Conjecture seems natural in the sense that it includes all the sequences we already had, but also many other sequences "in between", like when the Gamma Function generalized the factorials

Im curious how you define the relationship between what you call nodes, and a given fraction. Because in the Collatz, this definition is predetermined by the integer itself. 5 will always divide 4 times to 1. 71 will always divide only once to give 107. And then you know what kind of key it is in your system. But with a fraction, there is nothing stopping you from just dividing forever, so how do you define what key belongs to what fraction? Stepping from rationals to irrationals just makes it even worse. You should do a second video just going into more detail of your algorithm and how it is handling fractional inputs. Clearly I missed something. ;)

@@ianallen738 It's really simple Let's say you give me a constellation like STTLS, then I can calculate the equation of that constellation and I can find all the integer values of a0 that will give me valid Collazt Sequences But the same formulas could also result in non integer values of a0. Then I could use the formula for a Sartk node with that value of a0, take that result and use it in the formul for two Targaryen nodes, and keep going until I finish the constellation What I end up with are a bunch of non integer values that nonetheless satisfy the equation for the constellation and they satisfy the equation of each kind of node In summary, we took the Collatz Rules, we found the behavior they create, and we realized that behavior is not limited to integer numbers. We found the formulas using integer numbers, but they work with any number

the "X" in "TeX" is pronunced "K" since is a greek letter. Just like the statistical test "X squared"

There was a rather famous problem of finding an Einstein tile, a single tile that tiles the plane without repetition. Such a tile was found by David Smith in November 2022. Smith was passionate about tilings, but by no means a working mathematician. The paper _An aperiodic monotile_ was published in March 2023.

Naming the different types of nodes after GoT families is like naming a hockey stat you invented after like, your gamertag or something (that actually happened btw)

Well, there were three families, and these were the first three families that came to mind

I belive the "Super Awsome Tree" is not an extension of the Collatz tree. You just generate squences with specific tiles applied, regardless if the numbers are odd or even.

at 54:00 when you tried 1/8 as the input for your code, you said "integers", even though the last number was a fraction. I don't know if it changes anything, but I'm just letting you know.

The distance between nodes: Let 2n + 1 be any odd number. It must be followed by the node 6n + 4 (you can also get there from 12n + 8). As the node is even the next number is 3n + 2, which can't be a node, but it can be even or odd. Case A) If it is odd, it must be followed by another node (9n + 7). So assume instead 3n + 2 is even, and thus n is even, say n = 2m. Then 3n + 2 is followed by 3m + 1. Case B) If m is odd, you could've arrived there from m as well, so 3m + 1 again is a node. Case C) The last case is when m is even. Then 3m + 1 is odd and thus must be followed by the node 9m + 4 (which can also be reached from 18m + 8). So in any sequence, between two nodes at most 2 other numbers can occur (and at least one other number must occur). An example with all cases: 17 52* 26 13 40*(C) 20 10*(B) 5 16*(A) 8 4*(B) 2 1. The nodes are marked with an asterisk. Note that 4 is a node because it follows 8 but also follows 1.

There are techniques which enable you to extract the beahviour of expansion of generating functions. Perhaphs, by reformulating the Collatz Conjecture into combinatorial problem (your structures) could give us better insights and perhaps, by approximating its generating function at infinity could give you some hints whether there is or is not infinite tiling of yours.

34:15 i think u have it right there why it could converge, infinity minus infinity being an indeterminate form could maybe converge for certain values of mk and mh, basically write it as a ratio of 3^( Σmk) /2^(Σmh), taking logarithm we get a summation of what could possibly be fractions for certain sets of mh and mk

Hot diggity dog, dude that ending!! I didn't understand but suddenly it made sense. I never thought that anything but integers could be in the Collatz conjecture, but of course we should have instances where fractions would appear as we are talking about all real numbers up to infinity.

The definition of the collatz conjecture depends on the input number being even or odd. How can you tell if a fraction is even or odd? What Fer seems to have found is some other collatz-like relationship between numbers which is chaotic like collatz (it literally is using the patterns of multiplication and addition taken straight out of collatz, because those are the GOT House nodes), but it's using them on the wrong numbers. One string of a collatz sequence may say "multiply divide multiply divide divide" because the numbers are odd even odd even even, and Fer's program reads that as SL, but at the end, it seems to be using the SL pattern on a starting number that doesn't follow that pattern in the collatz tree. That's why it goes off the rails into non-integers. I think just about everyone gets a bit lost and rambley from trying to think about the collatz conjecture though. I'm probably wrong even though I think I'm right talking to you. At least its exercise for the brain.

Can you check if all integer solutions that come when you plug in follow the collatz rule, that is to say if you try the sequence that starts with 82, but change b so that it starts with 164, does it follow the collatz rule?, and also can you have different sequences starting from the same value by putting in fractional values?

25:00 - Interesting insights so far, and maybe it does point the way towards a formal solution, but maybe we need to stretch the definition of “solution.” The Conjecture basically says that you’ll always run into a power of two and that there are no closed loops. Both have to be proved to satisfy the conjecture. Assuming that loops could be disproved, the existence of a starting number that never resolved to a power of two would imply an infinite number of starting points that never resolve to a power of two, and therefore an infinite number of independent galaxies or regimes of integers that never coincide. You’d perhaps discover a new class of number. Approaching Collatz as “purporting to seed an infinity of disparate and non-intersecting infinities” might “prove” that doubting the conjecture is absurd. On the other hand, if “any sequence” of connections is possible, one which never intersects another might be out there. It sounds like your technique to find any pattern would be unable to pick such a number, therefore that number lies outside of the entire space of the integers.

Love the Phyrexian shirt!

I notice you came to some conclusions I came to as well, but in a completely different way !

is the collatz conjecture only in the real number system or can we take it to the p-adic infinity number, because there are many more loops in the p-adic system, especially when considering 1 as a large number, although I think the p-adics can fit in the real number system possibly proving the collatz conjecture wrong for infinite terms?

Super awesome! Near the beginning, when you decided to look only at "nodes", I thought it might be interesting to look at the tree you get if you give each number two parents which can be generic rational numbers not just integers, making all numbers into "nodes". I think the results you get at the end with sequences with fractional numbers are sequences in this "completed" tree. I'm not sure what's going wrong with the equation for infinite sequences, but I think there's a couple things to note. Firstly, we could pretty easily create an equation for an arbitrarily large increasing sequence of nodes, but like you noticed, if we made it infinite the starting point would also become infinite so that's not that interesting. Secondly, the divergent form you give with two divergent infinite sums in the exponent ... just doesn't really seem to be telling us much. Conceivably we could string together tiles in some ways which cause the coefficients to converge to irrational numbers (which might mean that such "threadings" are impossible), or other ways where the coefficients diverge (also meaning such a threading is impossible), but we can't prove that all infinite arrangements of tiles map to irrational/infinite coefficients. When you recast the equation to have two infinite sums in the exponent, it becomes an indeterminate form so we can't even tell if the coefficients are finite/infinite or rational/irrational. I expect that it's really hard to find exact values for these coefficients in most cases, and the worst part is that most infinite sequences of tiles are just random and so hard to think about as the limit of finite sequences (sure every infinite sequence is the limit of its finite subsequences, but even after a sequence of arbitrary finite length it is exactly 0% of an infinite sequence). But I didn't completely follow that part or especially how the equation for all cycles was derived, I would probably have to read the paper

I did some very brief playing around with this after being inspired by your video, one thing I found is that for each odd number that increases (4n-1), the next odd number they arrive at increases by one each time, (for example, 3 -> 10 -> 5, which is 1 odd number away, 7 -> 22 -> 11, which is 2 odd numbers and so on). Since those numbers are 2, 4, 6, 8... apart, only half of those numbers will go to another odd number that increases again (only multiples of 4 apart). Multiples of 8 will hit 2 increasing odd numbers, and so on.

4n-1 numbers increase in a way where they only hit an even number once before returning to an odd, rather than running through multiple even numbers before coming back to an odd. I tested some options for n up to 20, and found that the more powers of 2 in n's factors, the more times it would result in another 4n-1 number when run through the collatz machine. My conclusion is that the number (2^n)-1 where n is very large, would be a great candidate for a 4n-1 increased odd number The math works like this: (2^n) - 1 -> 3(2^n) - 2 -> 3(2^n-1) - 1 We've basically traded one of our powers of 2 for a power of 3, and our resultant number is still of the form 4n-1, so it will undergo the same process, turning powers of 2 into powers of 3. With many powers of 2, you can get a very high number of the form 3^n - 1.

This is absolutely an amazing video and really inspiring. I hope the first 5 minuted of your speech about why we should try doing thr impossible on our own goed viral. Think more mathematicisns and physicist needs to think like that.
