A Simple Experiment Could Change Our Understanding of Quantum Reality

The rules of the quantum world — where everything is probabilistic, until observation fixes it — may be a lot less indefinite than we thought. A new experiment shows that liquids have properties that physicists once thought were confined to the quantum level. And this could be a big breakthrough. » 6/30/14 11:05am 6/30/14 11:05am

This Mathematical Model Shows You Exactly Where to Park Your Starship

You may have heard of Lagrangian points — they are five gravitationally stable locations around our planet, created by the forces exerted by the Earth and Moon on each other. They're a perfect place to put a satellite (and indeed we have). In this incredible model, you can see exactly where they are, and why. » 6/19/14 3:40pm 6/19/14 3:40pm
