A recent study conducted at Tel Aviv University has devised a large mechanical system that operates under dynamical rules akin to those found in quantum systems. The dynamics of quantum systems, ...

The Earth rotates, and where you are changes how you see the universe. We are introduced to Foucault’s pendulum. Moving under the influence of gravity, over the course of a day the pendulum’s ...
