Physics students and their undying love for the "spherical cow" approximation! 🐄🔮
The top panel shows the excited physics student proudly presenting their simplified model: "Assume the cow is a perfect sphere with uniform density!" Meanwhile, the nutrition teacher below is completely done with hearing this ridiculous simplification for the nth time.
For the uninitiated, the "spherical cow" is physics' most infamous simplification trick. When a problem gets too complicated, just pretend everything is a perfect sphere in a vacuum! Problem solved! (And nutritionists everywhere collectively facepalm.)
