The beautiful irony of mathematics education in one comic! We start with kindergarteners flexing their numerical muscles writing "infinity plus one!" Then pre-algebra students solving for x (probably getting -2.67). Calculus introduces that delightful sine integral that most students will botch spectacularly.
But the punchline? After all that sophisticated progression, PhD cosmology students are just measuring the Hubble constant (still being debated to this day), game theory folks are trying to outsmart their classmates, and then—full circle—postgrads are back to "what's the biggest number?" just like kindergarteners.
Twenty years of mathematical education just to end up asking the same question you tackled at age 5. If that's not academia in a nutshell, I don't know what is.
