since the beginning of the school year, i've been watching pure documentaries and shit. like history channel, animal planet, discovery channel, and national geographic. i've seen blue planet, planet earth, tons of those shows on the lost cities, human weapon; pretty much prime time television on those channels.
pbs hosts this other 3 part series, elegant universe. so far i've seen the first episode, Einstein's Dream. basically an hour presentation on how physicists are trying to find this one theory/equation that relates everything in the universe.
they've come across this theory called "string theory" which as far as i can understand, immensely tiny "strings" make up everything. its actually cooler than that last sentence just sounded, but if you can watch it, do it.
and if you're really high, the colors and everything described will probably blow you away.
