One big application of Mersenne primes, that came from studying perfect numbers, is a good random number generator. RNGs had been historically very bad, until the introduction of Mersenne Twister in 1997, which uses a property of Mersenne primes to prove a good randomness. The most popular version uses a Mersenne prime 2^19937 - 1 for example, hence the name MT19937. There exist much more performant RNGs than Mersenne Twister now, but Mersenne Twister is still widely used thanks to its initial impact.

Video is well done. I'm a mathematician some of whose work has been on this topic (some of the results you put on at 23:51 are mine, and one is due to a joint paper of me with Sean Bibby and Pieter Vyncke). My apologies also for the length of this comment. I do have some quibbles about some of the history details but they are minor. (And it is possible that I'm getting some of the details wrong myself.) Descartes's construction of a spoof perfect number, shows he had a pretty good understanding of how sigma behaves. Descartes's spoof shows he had a pretty good understanding of sigma(n). Also, Descartes likely did prove that an odd perfect number must be of the form he suggested. What Euler did was a bit stronger. Euler showed that if n is an odd perfect number n= p^e m^2 where p is a prime , p does not divide m, and p and e are both 1 (mod 4). Notice that this implies Descartes's result. Regarding the Lenstra-Pomerance-Wagstaff conjecture, while it gives a specific estimate for how large the nth Mersenne prime is, there is some degree of doubt of if it is correct. We're much more confident that the conjecture is correct up to a multiplicative constant near 1. And we are much much confident that there are infinitely many Mersenne primes, even if LPW turns out to be wrong even on the order of growth of Mersenne primes. Regarding Pace's comment to high school students, I want to expand on that slightly. No one should be working on this problem with any hope of solving it any time soon. The problem is genuinely very difficult. The spoofs are in many respects a major obstruction to proving that no odd perfect numbers exist. In particular, many of the things we can prove about odd perfect numbers, also apply to spoofs. So if they were enough to prove that no odd perfect numbers existed, we would have proven that no spoofs exist, which is obvious nonsense. To use an analogy that my spouse suggested a while ago: If we are trying to convince ourselves that Bigfoot doesn't exist, but all we've done is list properties that all mammals have, we can't hope to show Bigfoot isn't real. There are few other big obstructions, one of which has a very similar flavor. But, Pace correctly notes that not that many people are working on the problem, so there may be more low hanging fruit than one would otherwise expect for aspects of the problem. For most really famous open math problems, like say the Riemann Hypothesis, or P ?= NP, lots of people have spent a lot of time thinking about aspects of it. So most mathematicians have a general attitude of not trying to bash their head against problems that a lot of other people have thought about. But in the odd perfect number situation, to some extent, the community may have overcorrected, and thus spent less time on it than they might otherwise. However, this may also be due in part to the odd perfect number problem being famous, but not by itself being very enlightening in terms of what it implies. Hundreds of papers prove theorems of the form "If the Riemann Hypothesis is true then " . And those papers are themselves very broad and varied in what follows after the then. In contrast, I'm aware of only a handful of papers with results of the form "If there are no odd perfect numbers then" and what follows after the then is always something involving divisors of a number in a somewhat straightforward fashion.

The end of your comment reminds me of my Mentor saying one time that part of him hopes someone disproves the Riemann Hypothesis just because of all the papers hes read on "if the Riemann Hypothesis is true then X" and how they'll all have to be withdrawn. He thinks its true fyi. I wouldnt call myself an odd prime "truther" but I see no reason infinitely many couldnt exist just the first one being say > 50th Fermat Number would put it out of search range for the forseeable future. Then one about every billion more digits.

I do not mean, seek intend or wish to be or appear to be impertinent, but it is interesting to me that the piece contains a misuse of the word "*perfect*"(which means finished completed or accomplished). why not just call them some short(quick-to-type) word like pig, ant, or god numbers, given that perfect is taken to mean neither more nor less than any-thing-you-please? "When I use a word, Humpty Dumpty said in rather a scornful tone, ‘it means just what I choose it to mean - neither more nor less.’ ’The question is,’ said Alice, ‘whether you can make words mean so many different things.’ ’The question is,’ said Humpty Dumpty, ‘which is to be master - that’s all.” Might it be relevant that Charles Lutwidge Dodgson(aka Lewis Carroll) was also a mathematician? In what respect or particular are the "perfect numbers" spoken of in the piece finished completed or accomplished or could be *said* to be finished completed or accomplished? Various people have said that mathematics is strictly a young man's game, might that be true? Please forgive me if I am being impertinent; as there can be the arrogance of youth, so also can there be the impertinence of senescence It may be that any potential to be interested in mathematics can be snuffed out by what is called " education.

Very nice video! Just a small thing, the reason why the largest known prime is almost always a Mersenne number is not because it grows so quickly (for example numbers of form 2*3^n-1 would grow quicker...), the real reason is because we have efficient test for numbers of that form so we can test them much faster (the Lucas-Lehmer primality test).

Ironically, the test is so efficient that someone skilled at arithmetic could perform it using pen and paper in some hours or days, for 15-20 digit numbers. Mersenne's "all time would not suffice" claim was likely based on trial division … the oldest and least efficient primality test. The test goes like this: Let n be an odd prime. (NOTE: a prime exponent is necessary anyway, so other than ruling out 3 = 2^2 - 1 this is w.l.o.g.) Construct a sequence S(i) with: S(1) := 4 S(k + 1) := S(k)² - 2 p := 2^n - 1 is prime if and only if S(n - 1) is divisible by p. E.g. n=3 is an odd prime, p=2^3 - 1 = 7, S(3 - 1) = S(2) = 14 = 2 * 7, therefore 7 is a Mersenne prime. Crucially, because only divisibility matters in the end, it suffices to calculate the remainders of the S(k) modulo p, which prevents the intermediate results from growing very large.

26:17 "Carl Pomerance predicts that between 10 to 2,200 and infinity, there are no more than 10 to the (power of) negative 540 perfect numbers." I'm not good at math. Can anyone tell me why that number is to the negative power instead of positive power? As far as I know, 10 ^-1 = 1/10^1 = 1/10 = 0.1 10^-2 = 1/10^2 = 1/100 = 0.01 Therefore, 10^-540 = 1/10^540) = 1/ (1 followed by 540 zeros) = 0. (539 zeros)1 10^-540 is less than 1. However, 51 perfect numbers have already been discovered, so how can the there be no more than 0. (539 zeros)1 perfect numbers in Carl Pomerance's prediction? Is there an error somewhere?

I just had a thought about primes. Has anyone figured 'primes' for fractions? What I mean is, instead of using whole numbers, try using a small fraction, such as 1/1298ths as your potential prime, and figure out if any two larger normal fractions multiplied together can make the smaller one. Or some other scheme using fractions to find fractional 'primes'. I'm thinking some cool new mathematical knowledge could be found, or a cool pattern.

Terrific video. However, the part about Edouard Lucas could have been much stronger. He did not merely show M_67 was not prime, he was able to show M_127 was prime. This is the largest prime ever found without the aid of a computer. He did so using novel methods that did not rely on trial factorization, but rather exploited properties of the Fibonacci numbers. Using his methods he could test M_n for primality for all n equivalent to 3 modulo 4. These methods were further refined by D. H. Lehmer (who also should have been mentioned) so that all M_n could be tested; giving us the Lucas-Lehmer test for Mersenne primes. It is this test that makes GIMPS possible. For more informations see "Edouard Lucas and Primality Testing" by Hugh. C. Williams.

In my intro to abstract math class in college, we had a final project to write a paper that had basically only two requirements: it was about an approved math-related topic and it had a proof that used concepts we were taught. I did mine on perfect numbers and Mersenne primes and gave a proof of the Euclid-Euler Theorem. It was super fun to learn and write about. It is awesome to see Veritasium cover this topic in the amazing quality he does and recognize the stuff that was talked about. I even concluded the paper like the video - it's nice to study stuff just because it's interesting, even if there's no obvious real world uses.

In the late 80’s/early 90’s I was involved in a research project into “probable primes”. These were numbers that aren’t mersenne, but rather the outliers that had no known factors. Some were remarkably small in comparison to known mersenne. I was an undergrad in applied math initially writing code, a theoretical math prof working a number theory hypothesis, and my comp sci phd for my masters refining code for distributed computing. At the time these “probable primes” being smallish had very practical applications if truly prime or not. If they were, crypto use could result in fewer compute cycles. If not prime, and yet used in another’s crypto, you had factors to simplify decryption. There were successes

It makes a fairly decent random number generator. Flip to a page and stab your finger at a number. Just skip the first and last numbers (the first is more likely to be 1 (I think, I might be thinking of something else), and the last is odd). It's also kinda like a code pad, but less secure since there's lots of copies of it out there. To be truly secure there should only be 2 copies of a code pad. It's unbreakable though since the data is completely masked by randomness. Assuming the pad is created in a truly random manner.

I loved math and science so I majored in engineering, but now I wonder if I truly loved math. Based on this vid, I now think I loved math up until about the college senior level. Past that, you start getting into math that, initially at least, doesn't appear to have any real practical usage, and engineers are all about the practical use of things. This show has shown me that I may like math some, but not near like that of these mathematicians. I still appreciate them because sometimes when they are pursuing some math problem of apparent inconsequence, they stumble upon a field of math that has some practical usage (negative numbers probably being the best example).

Finally I installed it in my laptop in 2019 when I came to the States for higher studies. Currently my dad is retired and the program only runs in my laptop. I have donated computing power to show that more than 50 numbers are not prime, still looking for one. My wife pokes fun at me when around every two to three months the LL test (or now the PRP test) on a potential number nears completion as everytime the number has turned out to be not a prime and I have been sad, and my wife finds this ritual mildly amusing.

The real benefit of solving those kinds of problems is usually not the solved problem itself, but the insight you gained while solving it and the kinds of techniques and methods developed beeing useful in other areas where you didn't expect them to be useful. Noone knows whether the tool you invented to solve this kind of problem will suddenly crack open other problems as well in (at first glance) unrelated fields of mathmatics. Edit: Thats also the reason why proving something simply by checking all possible cases with a computer isn't very well respected by mathematicians. Sure, you may have the proof that something does/doesn't exist, but it tells you absolutly nothing about *why* it does/doesn't exist. Your understanding of the topic is still the same as befor....

Decided to give it a go using pascals triangle. I found that the row with a perfect number generates it using consecutive sum of the row number - 1. So, [(n-1)n]/2 where n is a row in pascals number. Also, I found that each row number that generates a perfect number is a multiple of the previous row numbers. And since the first row with a perfect number is row 4 (the sum being [3(4)]\2 = 6, each following row must be an even numbered row. And since it's the consecutive sum of n-1, the perfect number would also be even because the consecutive sum of an odd number is even. My only problem is proving each row with a perfect number is an even numbered row. Or at least a multiple of the previous row numbers that generate a perfect number

Euler also worked on an interesting related problem involving "amicable numbers". Those are integers m and n where the sum of the proper divisors of m is n, and the sum of the proper divisors of n is m (so a perfect number would be where m=n). At the time, only a handful of examples were known, but Euler managed to come up with a recipe for generating many more. With one paper, the number of known pairs went from 3 to 61.

@@MathFromAlphaToOmega from my basic understanding, that open question would be quite analogous to the Odd Perfect Number question. Likely, the optimal known method for searching for such numbers would ALSO be running a vast network to reach insane levels of compute, for a few decades. Not likely something searchable in an individual’s free time. However, that is an assumption, unless there’s a proof that the problems have a certain equivalence. If there isn’t, then maybe there’s a different approach waiting to be found! And breakthroughs in number theory ARE things that individuals have accomplished, as illustrated by this video.

Not only did he immediately agree with a contradictory statement and not let his own beliefs that "Odd Perfect Numbers don't exist" overpower him, but simultaneously, he also reexamined and concluded that he had a bias. The same theory that heuristically shows Odd Perfect Numbers don't exist also shows that large, even perfect numbers don't exist. This is a true sign of intelligence, not to let your ego get in the way and search for the truth. We all can have biases, but only intelligent people will be able to look past them.

Similar to problems like the Riemann hypothesis and 3n+1, if it's unprovable then it must be true, since it being false means there exists a counterexample. It can't be unprovable and false because there exists a defeater. If ZFC isn't strong enough to prove a result then you can keep adding axioms until it is, but it is impossible to know if any system at ZF's strength or stronger is consistent (you can prove it from stronger systems but this just pushes around the problem). Which leads right into Veritasium's video about the hole at the bottom of mathematics.
