The eternal battle between mathematical precision and physics practicality on full display!
On one side, we have mathematicians having an existential crisis over calculus. The chill mathematician says "Just multiply by dx..." while the purist is literally crying because "derivatives aren't fractions!" (Spoiler: they technically aren't, but don't tell engineers that.)
Meanwhile, physicists are over here casually agreeing that cows are perfect spheres. Because why complicate your equations with pesky reality when you can just assume everything is a perfect sphere in a vacuum? Problem solved! Nobel Prize, please!
Next week: biologists debate whether mice and elephants have identical metabolic rates if you squint hard enough.
