    Electron was discovered in 1897. If you own a textbook on chemistry which is older than that, put it up on Ebay in the antiques category.

    Mathematics teacher: That textbook was written thousands of years ago, and it is still as useful and relevant as ever, but I want you to buy this one I co-authored instead for the mere sum of $120, otherwise you won’t pass.

    Computer programming books … Lol we don’t print them any more, they’d be obsolete before hitting the shelves.

      Do be fair, that’s less because the fundamentals behind programming are changing and more because the specific implementations are changed all the damn time.

        Yep, I got that “introduction to algorithms” (1100 pages tightly written, love it) and it still holds up ofc. I should have stayed in uni…

        Well Pythagoras lived during the Greek era. Buildings like the Temple of Artemis were the greatest projections of power and grandeur the world had to offer at the time. Those great structures would’ve dwarfed anything seen out in the country. The only way those buildings could ever be erected is with the help of mathematics.

        Furthermore mathematical truths are about as true as anything can be in the world. A triangle’s angles are always perfectly in harmony for instance. Way back when, when the world was much darker and more chaotic, those mathematical truths must’ve seemed like a great light in the darkness.

        Mathematics is applicable truth.

    Theres a lovely scene in Star Trek where Picard is captured, then finds an exposed wire on the cell panel. He takes it and begins tapping out prime numbers, to show to the aliens’ mathematicians that they’re sentient and capable of thought, independent of language.

        The other way around. Computer Science studies the implications of physical laws - the relation between space and time, what’s ultimately knowable given the make ups of our universe, etc.

    Math is a thought game with axioms as rules. It’s much more stable since the rules are “self-evident”.

    That $300 stack of the cheapest thin paper was last semester. The online code you need for class is void, and the questions won’t match the answer key.

      Calc 1 & 2 were fine for me. Calc 3 I either couldn’t get because I didn’t apply myself at all or my professor was terrible. 4 grades. 2 tests totaled 95% of our grade, 2 quizzes that equaled 5%. Got a 100 on the first quiz they said to use as a “progress report”. Got a 60 on the first test. Clearly the quiz wasnt a good way to tell my progress.

    The really funny part is the other two are also just math.

    The fabric of reality is woven from math, and that’s beautiful.
