Fyi, there’s a lot of woo woo (edit: apparently racist term) crap out there that tries to make you believe that somehow the photons can feel that a human is watching them and they choose to behave differently as a result. This is not true. It just means that when you use a detector or some sort of probe that physically interacts with the photons they change their behavior. It’s not magic.

NO FAIR! You changed the outcome by measuring it!

Fucking brilliant! And all of the upvotes assure me that I’m hanging out with the right bunch of nerds on the internet!
