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 ...

Being Isaac Newton: Computer derives natural laws from raw data
If Isaac Newton had access to a supercomputer, he'd have had it watch apples fall - and let it figure out the physical matters. But the computer would have needed to run an algorithm, just developed by Cornell ...
