Google has tech talks, which can be pretty cool. Today I went to a talk about quantum mechanics, which seemed a little overwrought and too complex for one hour. Still, the core message was fairly clear and very enlightening: observation and entanglement are the same thing! That actually makes a lot of sense–if a particle is observed, then its state and the observer’s state become related. As I recall, the definition of quantum mechanical “observation” was never clear to me, but this makes sense at last.
