A college physics professor was explaining a particularly complicated concept to his class when he was rudely interrupted by a pre-med student.

"Why do we have to learn this stuff?" one young man groaned, arms crossed. "We’re going to be doctors, not physicists! When will we ever use this in real life?"

The professor, an older man with a sharp wit, paused for a moment, then smiled. "Ah, excellent question! Let me give you a practical example."

He walked over to his desk, picked up a basketball, and held it at chest level. "Imagine this is a human head," he said, dropping it. The ball bounced back up.

Then, he grabbed a second, much smaller ball and placed it right on top of the basketball before dropping both together. The smaller ball shot up like a rocket, nearly hitting the ceiling.

The class gasped.

The professor turned back to the pre-med student with a grin. "Now, imagine this is a patient’s skull and their brain inside it after a car accident. If you don't understand physics, you might not understand why concussions happen… and that might be a problem for a doctor, don't you think?"

The student blinked, swallowed, and nodded quickly.

"Good," the professor said, tossing the basketball back onto his desk. "Now, let’s continue before you also need a physics-based explanation for how embarrassment works."
