When people talk about the physics of American football, they normally mention force, torque,

But there's another aspect of physics in football that isn't talked about as much – symmetry!

You might think symmetry is just for butterflies and rorschach tests, but it's all over the

move up or down the field, and rotational symmetry when they switch sides after a touchdown.

Even the ball has axial symmetry so it can spin smoothly through the air.
Sogar der Ball axial-Symmetrie hat, also kann es weich durch die Luft drehen.
But why is symmetry useful in the first place? Symmetry makes things easier, or at least more efficient; it gives you a guide: "same scenario, same action."
Aber, warum ist Symmetrie zuerst nützlich? Symmetrie macht Dinge einfacher, oder mehr effizient. Es gibt einen Plan- “gleich Situation, gleich Aktion”. Das meint, daß man muss

So when football players practice a play over and over, the patterns of football become

Psychologists call this "habit formation"; we call it "symmetry in time"!

Even physics itself is symmetric – ever heard of Newton's law: "a body in motion tends

Ultimately, symmetry is what allows both science AND football to function - if the laws of
