Quantum mechanics and experiments with particles have taught us that the world is a continuous, restless swarming of things; a continuous coming to light and disappearance of ephemeral entities. A set of vibrations, as in the switched-on hippy world of the 1960s. A world of happenings, not of things.
If you are passionate about how the world works, don’t miss “Seven Brief Lessons on Physics” by Carlo Rovelli. It’s a great book!
