       | This sounds big. Can some mathematicians please weigh in.

           | Thanks. This is a fascinating rabbit hole in itself
           | regardless of the merit of the claims, because I was unaware
           | of how rapidly advancing experimental mathematics is banging
           | heads with traditional work.
           | 
           | I see the problem, which goes deep into issues of ML/AI, that
           | interesting results without "proofs of understanding" are
           | "Idiotic" in the original Greek sense - that they stand alone
           | and separate from the wider corpus - leaving someone else the
           | work of "connecting them up", as it were.
           | 
           | Am I even half right?

         | There are a lot of continued fraction formulas for mathematical

         | 
         | c = a(0) + a(1) / (b(1) + a(2) / ( ....
         | 
         | Here a and b are polynomials (this looks a bit more sensible in
         | their paper, I don't really know how to denote continued
         | fractions in ASCII).
         | 
         | If you stop this fraction at a certain point you get a fraction
         | like p_n / q_n. In general the value of p_n and q_n grow
         | extremely rapidly. Their conjecture is that if you look at this
         | fraction in its lowest terms then p_n and q_n grow _way less_
         | rapidly (exponential vs. a power of a factorial), but only if
         | the limit is a mathematical constant.
         | 
         | Obviously this can't hold for all mathematical constants, but
         | as a rule of thumb it seems to work well enough to identify
         | when two polynomials a and b correspond to some mathematical
         | constant or a combination of mathematical constants.

           | inductive proofs ("there are no uninteresting natural

           | Regarding the joke: "there are no uninteresting natural
           | numbers because if there were any, there would also be a
           | smallest uninteresting number, making this number
           | interesting, which is a contradiction"

             | I'd say not, mathematical constants are usually irrational

             | consistently in different contexts, so they're culturally
             | (and so ill-) defined. Such concepts are not uncommon in
             | mathematics, "canonical" springs to mind.
