Differentiability Memes

The eternal battle between mathematical rigor and physical practicality on full display! Mathematicians are having a complete meltdown over physicists casually using Taylor series expansions without checking if functions are even differentiable. Meanwhile, physicists are just vibing with their approximations, making the math work for them with zero remorse. That formula? It's the Taylor series expansion that lets physicists approximate nearly any function as a polynomial—the ultimate "close enough" tool that makes mathematicians cry themselves to sleep. The rigorous proof-lovers demand formal verification while the practical physics crowd goes "haha differential equations go brrrr." Pure math vs. applied science warfare at its finest!

First, our cheerful math student understands the well-behaved parabola. Next, she comprehends functions with occasional differentiability hiccups. But then... Weierstrass function has entered the chat . That last panel shows the mathematical equivalent of Lovecraftian horror—a continuous function that's differentiable precisely nowhere . It's like nature decided "Let's create something that follows exactly one rule while breaking every intuition humans have about smoothness." Every calculus professor has witnessed this exact facial expression when introducing pathological functions. The math gods created these monstrosities specifically to crush undergraduate spirits and keep mathematicians humble.
