Quantum physics first: Researchers observe single photons in two-slit interferometer experiment
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...
