40:00 on the generality of Category Theoretic proofs. My comment : There seems to me [that] the more abstract proofs don't refer to "accidents" of the particular representations in some field like topology or linear algebra and in that sense they're more fundamental: the reasons the theorems hold are closer to the underlying logic. This is also what Urs Schreiber was saying a week or so ago about Mathematical Physics. 1:09:08 She says she's beyond the stratosphere a lot of the time.

See We Do Not Choose Mathematics as Our Profession, It Chooses Us: Interview with Yuri Manin by Mikhail Gelfand . 1:59:44 on equivalences: I think this has metamathematical consequences. These two definitions of equivalence are logically equivalent, but the set-theoretic definitions admit higher non-trivial structure, such as that produced when you use Gödel numbered propositions?

Looking at this is as a solution to a computer security problem. We need a cost-effective way to make verifiable machine-readable data stores for loading small amounts (<2 KB) of binary data to make bootstrap loaders. That's a great little machine, but still quite difficult to make, I imagine. The card stacks are also difficult to maintain: Paper tape readers are easier to make, ... ... but I have not seen anyone demonstrate a paper tape punch (except one Japanese machine I saw a video of in 2023 which was just writing random bit strings to paper tape: see Paper Punching Machine Looks Like Cute Piece Of Computer History Past ) it was a whole thing in Japan, apparently. The mechanism is interesting: rather than punch each hole-position independently, most of these devices seem to apply the punch force to the whole row, and solenoids somehow set whether or not an individual position is punched. 切り替えリンク、完璧に動作している #紙テープパンチャー pic.twitter.com/tux7c5L8EA — Nii (@neet2121) September ...

Pierre Freyermuth, Anders Nielsen and Andy Geppert made a pixel display you can draw on with technology from the sixties and seventies. It uses a 6502 processor, ferrite core memory made by a German company and tiny 100 Volt neon tubes made by a Soviet company called Gazotron in Ukraine that are still in business somehow.
