When you throw a ball, it follows a perfect parabola. Newton said this is because forces push it moment-by-moment.
But there is another law of physics—a much stranger one. This law says the ball doesn't just "react" to forces. Instead, the ball "chooses" the one specific path that minimizes its Action over the entire journey.
But this creates a terrifying question: How does the ball know what the whole path looks like before it finishes the journey? Does the particle know the future?
In this video, we dive into Feynman Lectures Vol II, Chapter 19 to explore The Principle of Least Action. This is the concept that convinced Feynman that physics was beautiful. We explore the "Lifeguard Paradox," Fermat's Principle, and how this leads directly to the weirdness of Quantum Mechanics.
We cover:
The Mystery of the Parabola.
The "Lazy Universe" Hypothesis.
How Light "Sniffs Out" the Fastest Path.
Why Quantum Mechanics is the only answer.
