41 and more Ulam's Spiral - Numberphile
video description
A nuclear or atomic explosion in space would only irradiate the bomb components, which would vaporize, and the blast shield of Orion. I could be wrong, but that is what I understood. In space, that radiation would likely be negligible against the cosmic radiation already there. (Depending on proximity and shielding.
Yes, I am pedantic at times, but I just thought that this is a possible peaceful use of an energy source, primitive as it is, that we have learned to harness. Kind of. Just my E=mc2 cents.

8: 45 WRONG, they understood all about the nuclear fallout, unlike the contemporary hysteria where the perfectly habitable by now Chernobyl area is still cordoned off while the Iranian plateaus have 8x (or is it 80x) larger natural background level with large populations living perfectly happily there (sans the politics. The modern mumbo-jumbo is all based on unsubstantiated extrapolations of mortality graphs to the very low radiation levels (after dispersal in the atmosphere at high altitudes) whereas the actual figures are more than likely to just drop to PERFECT ZERO at some point.

I have discovered the method to generate all primes to infinity, not in a linear fashion though. There is a self similar pattern within the distribution of primes. It's not evident, but it is there. The key to understanding it is to first study carefully the proof of Euclid. I am just wondering about how this would affect the current situation of Cryptography. Would it be catastrophic since a lot of security systems are based on primes?

This is actually the theorem of disproving -It's the thought that counts. - reply to unappreciated birthday gifts. It's probably also automatically accepted as evidence for irreconcilable differences in a divorce court. Furthermore, Ulam's Spiral looks - to me - like a manifestation of some math version of pareidolia. It's likely just a case of hero warship for a boredom-doodle; not some divine discovery.

It's because of the n-2 term, you're adding the same numbers no matter what. I. e. 0, 1, 3, 5, 7, 9, etc. These numbers make up the sum of the next two side lengths of that spiral at any given point.
As for the primes, in a subject with infinite possible functions, some of them are bound to have extraordinary properties. Not that that makes them any less fun.

We've proven that there is an infinite number of primes separated by a maximum of 246.
Then a saw prime numbers interestingly organized on the sides of an hexagonal pencil in another video.
My instinct then told me to divide 246 by 6 which equals to 41. Then i see this video and i'm wondering if this is somewhat related.

why is the 41 shows two times when we put in a value of 0, and 1. I know it makes sense when solving the equation, but is it also because 0 and 1 are not neither primes nor composites. Why the 1 is not prime while in fact it can not be broken down into any other prime factors? 1

I think it's more intersting that the solution to the equation seem to rest on a line centered on a diagonal centered on an Ulam square starting at 41 (is that -C-.
Is that true for all of them when the coeffitients (is that the right word? The 1 in 1x is what I mean?

In the United States, instead of contracting the word, we're making an abbreviation. Just mentally replace the word -math- with the abbreviation -math. - including the period. A similar example would be -comm- versus -comms- for -communications. -

the number 41 in the Rama series first appears in Rama II. The prime series is General Michael O'Toole's password and it is explained in different (less formulaic) terms when General O'Toole's thoughts are narrated in that book.
