Uncle Petros and Goldbach's Conjecture

@tompurcell1499 7 лет назад

Likewise. I was once given the book as a present because of my (and I stress, layman's) interest in the problem.

@fatsquirrel75 7 лет назад

woohoo, a new math book recommendation. Maybe ask them all for suggestions. I'd love to grow my math library a little.

@HeavenlyTennyo 7 лет назад

Brady, I love hearing the questions you ask that catch the mathematicians! You're much smarter than you let on ;)

"Number theory has exploded in recent years." says Eisenbud. "I know!" says Brady, giggling and rubbing his hands together.

@emmaturrubiartesavila2379 3 года назад

Does anybody know if there's a link between Goldbach's conjecture and the Riemann hypothesis? I mean, imagine there's a connection that asserts that Goldbach's conjecture implies Riemann hypothesis :)))

@martinepstein9826 7 лет назад

Relating to Brady's question: Do the primes appear to be a minimal set for generating all even numbers > 4 by adding two elements? If not, what primes can we skip and still get sums for the even numbers calculated so far?

@martinepstein9826 7 лет назад

The numbers 3, 5, and 7 are necessary because 6 = 3 + 3 and 12 = 5 + 7 are the only possible sums for 6 and 12. A commenter on the 210 video claims that 12 is the largest known even number with only one sum. This implies that as far as we know the Goldbach conjecture is still true for the set of prime numbers \ {11}, since if every even number > 12 has at least two sums then they have at least one sum that doesn't use 11. So I'd like to know the next prime we can eliminate after eliminating 11.

My grandfather solved the Goldbach problem. We are from Kazakhstan. We just dont know how to publish it.

@jorenheit 7 лет назад

Could there exist mathematical truths that cannot be proven? If so, could that statement itself be proven to be true? If not, could it be proven to be false? (Don't say "axioms".)

@hexameron8603 7 лет назад

Lookup the continuum hypothesis. It was proven that starting from the ZFC axioms, you can neither prove it or disprove it.

@jasondoe2596 7 лет назад

Joren Heit, *yes*, and *yes*.

@linazso 7 лет назад

I think Gödel's incompleteness theorems are also about this topic

@jorenheit 7 лет назад

Lilla Kiss Ah! I thought that had to do with any set of axioms being unable to prove its own consistency, but that's actually just the second part of it. Thanks :-)

@jorenheit 7 лет назад

Hexameron So that would be a great example! Thanks, I didn't know about this :-)

@helloitsme7553 6 лет назад

From which even number on can even numbers be expressed as two distinct primes? Let's see. 2 NO 4 = 2+2 but those are not distinct so NO 6=3+3 so NO 8=3+5 YES. Will this keep going let's see. 10=3+7 YES 12=5+7 YES 14=3+11 YES 16=5+11 YES 18=7+11 YES 20=3+17 YES 22=5+17 YES 24=5+19 YES It seems to go on forever can somebody prove to me that an even number above 6 can always be expressed as two distinct primes? TY

@helloitsme7553 6 лет назад

Lol probably no one will be able to proof this or otherwise goldbach conjecture should be proven

@helloitsme7553 6 лет назад

If this can be proven, goldbach's conjecture is also proven

@helloitsme7553 6 лет назад

26=7+19 28=5+23 30=11+19 32=13+19 34=11+23 36=13+23 38=9+29 40=11+29

@htmlguy88 6 лет назад

You can equate goldbach's conjecture to every number greater than some value, is equidistant from two primes. Furthermore, the twin prime conjecturecan be restated as 6m-1,6m+1 is a goldbach partition of 12m infinitely often. The statement about two primes being a certain even number apart can be turned to general statements about goldbach partitions.

@reynaldovelasco5129 5 лет назад

@@htmlguy88 what does 12m mean?

@htmlguy88 7 лет назад

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.)

@hanishsutaria8105 7 лет назад

Why did he correct himself with 'arbitrarily many primes' instead of just saying 'infinitely many primes' at 3:09? Is there a difference?

@LeoMRogers 7 лет назад

I think the difference is that no individual arithmetic progression necessarily has an infinite number of primes, but there is no limit on how many there can be in one.

@hexameron8603 7 лет назад

Yes, I think so. Infinitely many primes in an arithmetic progression would mean that every arithmetic progression has infinitely many primes, which is false (2,4,6,8,10,...). Arbitrarily many primes in an arithmetic progression means that for any number k you can find an arithmetic progression with more than k primes. (Edit: too late :/)

@ben1996123 7 лет назад

infinite and arbitrarily large are not the same thing. there are arbitrarily large natural numbers, but there are no infinite natural numbers

@hanishsutaria8105 7 лет назад

There are infinitely many natural numbers just as there are arbitrarily many natural numbers

@hanishsutaria8105 7 лет назад

Oh right, that makes a lot more sense. I guess it's just a consequence of communicating through language instead of maths. Thanks!

@jm76464 4 года назад

The equations and proof that defines the prime number sequence were proven five years ago and subsequently the proofs to the Strong and Weak Goldbach conjectures as well as the Twin Primes at the same time. I enjoy your channel.
