🎓 Oh joy, a course on Applied Category Theory—because who doesn't want to spend their free time unraveling the mysteries of preorders and adjoints? 🙄 It's like the Avengers of abstract math concepts, minus the fun and special effects. Dive right in, they said—don't worry, there won't be any lifeguards. 🏊♂️

From a Mathematical Curiosity to the Foundation of Internet Security 🧮🧐🔐✨
In 1636, Pierre de Fermat made a remarkable observation: if you take an integer a, raise it to a prime power p, and then subtract a, the result is always divisible by p. In other words, for a prime p,
aᵖ ≡ a (mod p).
For example, when p = 5:
2⁵ − 2 = 30, which is divisible by 5, and
3⁵ − 3 = 240, which is also divisible by 5.Fermat found this property elegant and tried to spark interest in this curious corner of mathematics. Not everyone was impressed. John Wallis reportedly dismissed such results, remarking, “Big deal; I could find other relationships just as interesting without much effort, and none of them are important.”
About a century later, Leonhard Euler was encouraged by Christian Goldbach to study Fermat’s ideas. Though initially unenthusiastic, Euler soon uncovered deeper structure within them. His work laid much of the foundation for what we now call modern number theory.

🖼️🎮 Ah yes, the groundbreaking #innovation of "Gaussian Splat" gaming—because who doesn't want to spend their weekend turning an abstract math concept into a playable disappointment? #PlayCanvas flaunts splats like they're the new sliced bread, but we all know it's just an over-hyped Excel spreadsheet with graphics. 🥴🔢

📚🤓 Oh, look! Another mind-numbing dive into the abstract abyss of Category Theory, where somehow "natural transformations" sound like something out of a biology textbook. But fear not, if you squint hard enough, you might just see a functor magically morph into something more... or not. 🙃🔄
