There's a kind of ambiguity here. Predicting the orbits of the planets was something that could be imagined very early; the ancient Babylonians and the Maya were doing it at TL1. But they used horribly clunky approximative methods that couldn't be translated into physical models in any way that made sense. Then Kepler came up with the theory of elliptical orbits with the sun at one focus. At that point it was possible to envision finding exact solutions to astronomical problems—but that insight was, in essence, the answer to the problem. It wasn't a matter of "being able to envision the result" but "being able to envision the method." (Though ironically, Kepler's method relied on conic sections, which had been worked out at TL2. No one visualized them as solving the problem of planetary orbits, though.)

Re: [Basic] Skill of the week: Mathematics
My Hermetic Cabalist character, who's from an early 18th century timeline, has managed to end up with Mathematics/TL4 (Surveying) because of his old day job, /TL2 (Pure) because he's a Verdadera Destreza stylist, and /TL6 (Applied) because he's been studying the physical sciences in some more advanced timelines.
He doesn't roll against any of them much, and anyway to him they're all means to an end; he's a philosopher (and a would-be eikone, but that's a long-term project).

It does not appear that computer proof was involved in Andrew Wiles' proof of Fermat's Last Theorem. He didn't mention the idea in the lecture I saw about it in 1995, and according to the Wikipedia page about his proof, a challenge was set in 2005 to formalise a proof that can be verified by computer, which kind of suggests it didn't exist at the time. |

Re: [Basic] Skill of the week: Mathematics
Something I'd be curious about is where the lines between TL 5, 6, 7, and 8 mathematics get drawn. While it may be difficult to predict what happens at future TLs, we can finish doing for math what LTC1 started.

I think that's a very demeaning view of human science and history. Since Charles Babbage proposed what we would understand as a (modern) computer in 1871, it took only to 1931 for both infrastructure and human science for Alan Turing to start the mechanical calculator to defeat the German Enigma. Or the limited tools and information available for astronomy still allowing viewers centuries before Galileo to propose the idea - mathematically - that some of the 'irregularly moving stars in the sky' were planets all moving with earth when satellites and precise telescopes weren't available. |

The big thing between 6 and 7 is the discovery that formal logic has limits in mathematics, by way of the Gödel-Church theorems. The Turing proof about the halting problem is parallel, and in the course of working it out Turing comes up with the concept of automata theory, which gives birth to Mathematics (Computer Science). You also see the full efflorescence of fields such as abstract algebra, which will feed back into elementary particle physics with the identification of symmetry groups—an example of Mathematics (Pure) turning into Mathematics (Applied). I think the big things in going to TL8 mathematics mostly emerge from the presence of computers. Of course there are efforts to prove theorems by computer. But more important, I think, is the recognition that some systems are not predictable, even if we have exact equations for them, because they have sensitive dependence on initial conditions, and an error below the limits of precision of your computations can blow up to change the outcome in a big way (the famous "butterfly effect"). You also have the emergence of computability theory and the measurement of computational complexity. And Mathematics (Cryptography) takes off with the recognition of number theory as having practical significance. I'm sure a professional mathematician could point out other important developments that I've missed. But I think most of these are fairly big ones.

Re: [Basic] Skill of the week: Mathematics
That's a possible direction to look in, yes. See for example the fams in Kingsbury's Psychohistorical Crisis.
