Parity violation This might be why Camera violation Commentary

Tsung-Dao Lee, Chen-Ning Yang physics

Parity violation

• Everyone thought
• antimatter was to matter
• as matter is to a mirror.
• If matter spins right
• then antimatter spins left.
• But experiments
• violated expectations.
• It turned out
• the weak force violated
• mirror symmetry.
• Only the left-handed
• components of matter
• and right-handed
• components of antimatter
• participate in
• weak interactions.

This might be why

• We live in a universe of matter
• instead of a universe of antimatter.
• Masses must warp space
• or they would not congregate.
• Light must travel at a constant rate,
• not to be exceeded by anything.
• Energy must equal mass times
• the square of the speed of light.
• If it were not true, then we wouldn’t
• be here to suppose it otherwise.

Camera violation

• When I turn to my right
• looking in a mirror, I’m
• turning the same direction,
• which if you were facing me,
• would be to your left.
• Turn your head to the right
• to take a selfie
• with the camera on your phone.
• On the screen of your phone
• you’re looking in the same direction.
• In the photo, you will be looking
• in the other direction.
