Just a minute: how do polarized sunglasses work?
We briefly discuss how polarized sunglasses work, quantum fields, pilots, and 3D cinema.
quantum field theory
Is microwave oven radiation unhealthy?
We discuss what electromagnetic radiation is and why ionising radiation is dangerous. We discuss how a microwave oven heats up food, and vitamins too.
Why, exactly, do glass and liquids refract light?
We provide a semi-in-depth look into why glass and liquids bend light. We discuss quantum fields, Maxwell’s equations, and vectors. No calculations.
