Recuerdo de todos los organismos ~ Memoria de la energía fósil

You know how when some high school kid asks about whether non-real numbers 'exist' in some physical sense, one of the go-to answers is that voltages, currents etc. can be 'complex'. I've always found this very misleading, as it conceals the fact that what is being talked about is merely sinusoidal functions with different phases and not some sort of 'alternative voltage' or anything. If the kids aren't convinced by looking at a complex plane or vector rotations or something, they wouldn't be convinced by that if they understood it, the same way they wouldn't be convinced by, say, two dephased mass-spring systems.

Also, e and pi make no sense at all. Totally unreasonable. Why the hell are there numbers with non-repeating decimal patterns? It just

doesn't make sense!Our statics professor had some philosophical vendetta against negative numbers and how they were 'unphysical' and warned us that if we put a negative force somewhere in our exams, he'd grade it as 01 (the lowest grade), so we had to figure out the forces' sign/direction beforehand so we'd know how to make a free-body diagram. Thankfully in the problems we got they weren't hard to figure out.

(Haven't had a smaller one.)

the anti-NatSoc party was teaching a class on foundations of mathematics

and Kurt Godel, a known opponent of logicism.

"Before the class begins, you must get on your knees and worship Russell and accept that he was the most highly-advanced logical thinker the world has ever known, even greater than Frege!"

At this moment, a brave, formalist, intuinitionist, pursuer of true mathematics who had edited 1500 pages of Deutsche Mathematik in Nazi Germany and understood the necessity of restricted comprehension and fully supported all expulsion of all unintuitive mathematics stood up and held up a copy of the

transcripts of Hilbert's 1930 radio address

"How intuitive should mathematics be?"

The arrogant professor smirked quite Platonically and smugly replied "as

intuitive as the logical framework it is grounded on allows it to be.”

"Wrong. Unrestricted logical foundations of set theory has been shown to yield

pathological results and even paradoxes that one cannot resolve without

appealing to higher order logic. If mathematics were as intuitive, as

you say, as the axioms that ground it… then we should be able to

subdivide and arrange a set in such a way that it reassembles into two

identical copies of the original set in nature."

The professor was visibly shaken, and dropped his chalk and copy of Principia Mathematica. He stormed out of the room crying those logicist crocodile tears. The same tears logicists cry for "the destruction of Cantor's

paradise" (which has been shown to lead to many pathological counterexamples in analysis) when they try to corrupt the pure and aesthetic theorems from the intuinitionists. There is no doubt that at this point our professor, Schlomo Von Freudman, wished he had pulled

himself up by his own type-theoretic bootstraps and become more than a

Platonic logicist professor.

He wished so much that he could find the Devil's Staircase in nature in order to prostrate himself off of, but he himself had endorsed the proof of its zero measure!

The students applauded and all converted to intuinitionism that day and accepted Hilbert as their role model and beacon of intuition for mathematics. An eagle named “finitism" flew into the room and perched atop the finitely generated Sierpinski's pyramid and shed a tear on the chalk. The radio address was played several times, and Poincare himself showed up and forbidden the set theoretic construction of the natural numbers from publication.

The professor lost his tenure and lost his tenure the next day. He died of caffeine overdose and was forced to watch physicists summing divergent infinite series for all eternity.
