The footprints of five ancestors of humans who walked the Earth more than 3.6m years ago have been found preserved in volcanic ash that was dampened by ancient African rains.

Plato and Aristotle, as depicted by Raphael.
Are you the sort of person who always works for the greater good, or always sticks to moral rules? Perhaps you use a mixture of both? Or, maybe, are you neither of the above? Of course, do you know what you are if you are not one of those two?

Our current understanding of the Universe suggests that it is composed of an invisible component called “dark matter“.

We call this “ordinary” or “baryonic” matter.

Neodynmium magnets and a high speed camera? It turns out it is, as the kids say, oddly satisfying. I was practicing with some macro shots with the Chronos high speed camera, using LED lighting and filming at around 4000 frames per second. I dropped some hard drive magnets and noticed the magnets behaved very oddly and unpredictably.
