Definitely L'Hôpital's Rule

The mathematical apocalypse is upon us! A teacher's list of banned classroom words includes "Sigma, Beta, Alpha" - essentially outlawing the Greek alphabet that's fundamental to mathematics and physics. Might as well ban numbers next! Calculus students everywhere are frantically wondering if they'll have to refer to Σ as "that squiggly sum thingy" on their next exam. Meanwhile, physicists are silently weeping in the corner as they contemplate describing quantum states without Greek symbols. The classroom revolution we never saw coming: death by whiteboard!

Engineers approximating π as 3 is the mathematical equivalent of saying "eh, close enough." The calculator literally has a dedicated π button right there! But why press one button when you can be gloriously wrong instead? This is the same species that built the pyramids and landed on the moon, folks. The π button exists for a reason—and that reason is that π ≠ 3. Not even on Fridays. Not even when you're tired. Not even when your professor isn't looking.

Engineers are interviewing a tiny groundhog for the position of "small angle approximation" and the poor mathematician is having an aneurysm. For those who slept through calculus, when an angle is very small, its sine approximately equals the angle itself (in radians). Engineers run with this approximation like it's gospel truth, while mathematicians twitch uncontrollably at such blasphemy. The groundhog, blissfully unaware it's being used to represent θ, is just happy someone's pointing a microphone at it. This is the fundamental difference between theoretical and applied sciences - one needs absolute precision, the other just needs something that works well enough to build a bridge that probably won't collapse.

This textbook is basically saying "when your number is so massive it's stopped caring about small-time additions." Avogadro's number (10 23 ) is so ridiculously huge that adding 23 to it is like throwing a grain of sand into the Grand Canyon and expecting the tour guide to update the brochure. And then there's the "very large numbers" that are so astronomically gigantic they don't even notice when you multiply them by mere billions upon billions. It's the numerical equivalent of a celebrity too famous to acknowledge your existence. These numbers have transcended mathematical anxiety - they're just out there living their best life, completely unbothered by our operations. The footnote about "keeping track of leftover factors" is the textbook equivalent of a nervous laugh after making a dad joke at a faculty meeting.

Classic hypocrisy in STEM fields. We mock engineers for using π = 3 while simultaneously treating spherical cows as legitimate scientific models. Nothing says "I'm a serious physicist" like reducing complex biological organisms to perfect yellow spheres that say "mooooo." Next time you're simplifying a problem, remember you're just one "assume a spherical cow" away from being exactly what you ridicule.

Somewhere in Indiana, a math teacher just felt a disturbance in the force. Using π = 5 is like measuring your height with a banana and declaring yourself 7 feet tall. The real crime here isn't the wrong answer (5000 instead of ~3141.59), it's the mathematical sacrilege. Next thing you know, they'll be teaching that gravity is "just a suggestion" and electrons are "tiny marbles with feelings."
