Nature of Light, polarization and how the universe isn't deterministic

Awesome explanation of light and some super cool experiments that lead to very interesting questions about the universe.

A team-up between minutephysics and 3 blue 1 brown. I highly suggest you further look into both youtube channels, such as 3 blue 1 brown's corresponding video. This video describes what light is, how that reconciles with polarizers (such as your very own sunglasses), how light is made of photons, some cool quantum mechanical consequences, and how the universe probably isn't deterministic and why.
