    in case you didn't see my twitter comment you can also restate it as every number after a certain point is equidistant from two primes ( technically if you count distance=0 that's from 2 on, for distance>0 that's 4 on.)

    Again. The Collatz Conjecture If a number is even, divide by 2. If a number is odd, multiply by 3 and add 1. The Collatz Conjecture states that all numbers converge to 1. Due to the fact that all even numbers are contained within the power of 2 numberline, we have: n/2 = 2^s, where s are all positive integers. n = (2^s)(2) n = 2^(s + 1) Due to the fact that in order to make a number even we need to multiply it by 3 and add 1, we equal 3n + 1 to 2^(s + 1); we have: 3n + 1 = 2^(s + 1) 3n = 2^(s + 1) - 1 We equal s to the first strictly positive integer, that is, 1; we have: 3n = 2^((1) + 1) - 1 3n = 2^(1 + 1) - 1 3n = 2^(2) - 1 3n = 4 - 1 3n = 3 n = 3/3 n = 1 All numbers converge to 1.

    Euler was certainly a brilliant mathematician, but Euler had a tiny sliver of the mathematical machinery we have today. There are, undoubtedly, many problems Euler couldn't solve that undergraduate math majors today could solve. The difference between those problems and Goldbach's conjecture is that those other problems have already been solved by newer mathematical machinery, whereas Goldbach's conjecture has not. So I don't think it's incredibly optimistic to think that someone today could solve a problem that Euler couldn't. Any time a new mathematical idea or tool is developed, it could be the spark of inspiration or the missing piece to approach a solution. Eh, on second thought, I think the general sentiment I described in the above paragraph is rather optimistic after all :P

    I've been working on the Goldbach Conjecture for a little while now, and before I even watched this video, I had discovered or realized a lot of properties of numbers that I didn't know before, just through my own exploration of numbers. And it's startling how similar that triangle graph looks to something I was using (that I came up with totally independently) for a little while. And earlier today I happened to formulate a hypothesis which is basically Hardy and Littlewood's conjecture (any odd number is the sum of a prime and twice a prime). Kinda scary to see it in a video just hours after wondering about the problem myself.... Even though I may or may not be any closer to coming up with something (it's actually pretty hard to tell; so many ostensibly false leads), I still have found many interesting properties about numbers through my own research and logical exploration. Very fun project for a Numberphile :)

    I would guess that 2 can't be written as the sum of 2 primes, since 1 isn't a prime, and I suspect 0 isn't a prime either. While some claim that -2 and -3 etc are also prime numbers, they are in general not considered primes. But if we exclude negative numbers as primes. Then 2 is an even number that can't be written as the sum of 2 primes.

    Since there is no certain way to find primes I'd say, Goldbach's conjecture is the closest to one. If you take a number significantly larger than the largest known prime, you should always find a prime bigger than the largest prime known.

    Goldbach’s conjecture isn’t of any use in finding large primes. If you take a googolplex it obviously can be written as (googolplex-97) + 97. It’s easy to show 97 is prime but there’s no easy way to show (googolplex-97) is prime.

    I've wondered that too for a while. Apparently you need to start off by reading (booking up) all the relevant stuff that has been discovered already and the various methods that have been used/papers that have been published. Then you probably start by working on a smaller problem within one of the already established ideas. I don't think one would just immediately have a groundbreaking idea out of nowhere.

    JiaMing Lim , In my experience, throw things at the wall, see what sticks, read what other people have tried, try those yourself, read what people have tried for vaguely related problems, try those too. Repeat the above until something seems to not be there when it should, or be there when it shouldn't. That's the first grapple point. Keep working from that foothold until another is found, and just maybe, the climb proper can begin.

    Bonjour, Pour ceux que ça intéresse, je propose une résolution de la conjecture de Goldbach publiée sur KZread en 5 épisodes sous le titre générique "Variations Goldbach". Comme elle s'adresse à tout public, pour ceux qui veulent entrer directement dans le vif du sujet, une formule donnant la proportion minimale de couples de premiers au sein de l'ensemble des couples d'impairs dont la somme vaut un nombre pair se trouve épisode 2 et l'essence de la démonstration épisode 5. Le commentaire de J ci-dessous est tout à fait exact, mais en fait, il y en a beaucoup plus. Entre plus ou moins 10.000 et 16.000 le nombre de minimum de couples de premiers monte à environ racine carrée du nombre pair, et ça continue d'augmenter comme je le démontrerai dans l'épisode 6, qui clôturera cette série.

    Goldbach's Conjecture is, in many ways, the arithmetic equivalent of Noether'sTheorem in Physics. It involves the conservation of bilateral symmetry as the numberline continuously translates permutatively into infinity. As the foundational level, the primes are the numbers whose distribution maintains this continuity. In an infinite space or line, every point is a potential midpoint. Midpoint is perpetually arbitrary, which is what makes the mathematics/geometrics universally applicable. (Mathematics as a Universal Language.) This means that the system is necessarily always in an evenly bisected state, i.e., a balanced state, no matter how continuously the system is bisected. There is a law that every integer has an additive inverse and distances are equivalent as measured from either equidistant endpoint to midpoint. In order for this to be universally true, the most foundational layers, i.e., the primes, must always maintain this same balance throughout and must therefore be positioned equidistant at each consecutive bisection as midpoint moves arbitrarily through the system. The system maintains balance through the primes as composites are stripped away. The distribution of the primes, and therefore basic Peano arithmetic, is thusly just like an infinitely successful Jenga Tower. Therefore, the strong Goldbach Conjecture is necessarily true simply as a matter of a design built upon the principle of maintaining perpetual system balance. When the mathematical purists finally admit to themselves that they only speak the common language of physics and engineering, perhaps they will see the simplicity of both the Goldbach and Riemann phenomena. Mathematics and Logic begin with the notion of a Standard Unit determined by the equivalence provided through actual or theoretical bisection of a space. The Goldbach Conjecture is Architectural Engineering 101 and is equivalent to the most primitive axioms of arithmetic.

  • @Halosty45
    @Halosty457 жыл бұрын

    An interesting thing is that this can sort of be extended: For every even number, there are two primes an equal magnitude from half of that even number, the sum of which is the original number. For example: 8/2=4, 3 and 5 are both 1 away from 4, and 3+5=8 76/2=38, 29 and 47 are 9 away, 29+47=76 88/2=44, 41 and 47 are 3 away, 41+47=88 1.I obviously can't prove this, or I would say it's more than "interesting" 2.I can't say I have put as much rigor into testing this as other people have with their theories... only up to around 100.

    Halosty Yes, this boils down to: Every number greater than 1 has two primes equidistant from it. Given that the Goldbach conjecture has been tested extensively, this is also true as far as that's been tested. it's an interesting insight/way of restating the problem.

    Might that be due to the symmetry of adding two numbers, such as when Gauss summed the numbers from 1 to 100? Each prime is odd and either one more or one less than an even number. When you sum two primes, the difference from an even number is either 0, +2 or -2. So one gets into the definition of primes and multiplication by 2 in terms of addition.The density of primes is related to the increased number of possible permutations of primes created by adding 1 to the highest composite number formed by all of the previous primes. (2x2), (2x3), (2x5), (2^2 x 3),(2^4), (2x3^2).

    If the divisor is even then it's just a special case of Goldbach's conjecture. Who knows - there might be some special case that's more readily provable than the general case, but I don't know of it. If the divisor is odd then it's false. Multiples of an odd number will include the cases where the multiplier is also odd, giving an odd result, so to be the sum of two primes one of the primes would have to be 2. Whatever your divisor, eventually the primes will get too far apart for all odd multiples of it to be two greater than a prime.

From that Bertrand postulate will follow..Not sure if any prime is average of two other primes is a valid theorem, but interesting that a valid theorem ( Bertrand Postulate) comes out of it.
