What Is *Not* A Vector?

The glasses come OFF when math gets simplified! First panel shows the intimidating square root of factorial expressions (√4! × 3!) which equals √24 × 6 = √144 = 12. Second panel? Just plain ol' 4 × 3 = 12. Same result, way less showing off. Mathematicians love making things needlessly complex to seem smart, then privately calculating it the easy way. It's like wearing a monocle to read the back of a cereal box.

Calculus students everywhere just felt a disturbance in the force! Imagine showing up to your limit problem armed with L'Hôpital's rule—your trusty mathematical weapon for those pesky 0/0 indeterminate forms—only to find it's been "banned." The mathematical equivalent of finding out they've outlawed calculators during finals week! For the uninitiated, L'Hôpital's rule is that magical calculus technique that saves you when both numerator and denominator approach zero. Without it, you're stuck doing Taylor series expansions like some kind of animal. The horror! Next thing you know, they'll ban the quadratic formula and we'll all have to complete the square by hand. Dark times for mathematics indeed.

Pirates of the Caribbean? Nope, we've got Pi-rats sailing the mathematical seas! These rodent sailors are navigating by the most irrational of numbers. When asked how far the treasure is, the captain responds with "3.14" - because that's just how these Pi-rats roll. They don't measure in miles or kilometers, but in the fundamental constant that makes mathematicians drool. Next time you're lost at sea, forget your GPS - just bring a calculator and a cheese-loving first mate!

The mathematical equivalent of an identity crisis! The Jacobian matrix is sitting there like "I'm being called Yakubian? That's derivative!" 😂 For the uninitiated, this matrix (which contains all first-order partial derivatives of a vector-valued function) is actually named after Carl Gustav Jacob Jacobi, not some mysterious "Yakub." It's the mathematical equivalent of someone confidently mispronouncing your name at a conference and then putting it on your name tag. Next up: the Hessian matrix introducing itself as "that guy from Breaking Bad."

The student who thought calculus was useless just got schooled by real life! The headline perfectly captures the concept of derivatives vs. absolute values. When inflation falls , it doesn't mean prices go down—it means they're still going up, just more slowly! This is exactly what calculus teaches us: the rate of change (derivative) can be negative while the actual value remains positive. That student is probably kicking themselves now for not paying attention during those derivative lectures. Next time someone says "when will I use this in real life?" just point to your grocery bill!

Engineers have never met a problem they couldn't solve with a good approximation! When no one's asking for solutions, there's always that one engineer ready to whip out their calculator, scribble some equations, and proudly announce "So anyway, I started approximating." The beauty of engineering isn't finding the perfect answer—it's finding one that's close enough to work while everyone else is still defining the problem! That paper full of calculations? That's just Tuesday morning coffee thoughts.
