Everything in the Universe is connected in some way. That may seem obvious, because of course, all observable matter is composed from atoms, which, in turn, are composed of protons, neutrons and electrons, and so on down to even smaller particles. So yes, everything is connected by virtue of shared raw materials. But things get far more interesting as we move up the scale of complexity. A few simple parts and rules, like a language, express a limitless variety of objects and phenomena that we experience as the cosmos. We’ll explore simple systems with which we can unlock some of the most complex and obscure scientific discoveries and inventions.
