To summarize, quantum mechanics is the discovery of three features of the world: — Granularity (figure 4.7). The information in the state of a system is finite, and limited by Plank’s constant. Figure 4.7 Light is a wave on a field, but it has also a granular structure. — Indeterminacy. The future is not determined unequivocally by the past. Even the more rigid regularities we see are ultimately statistical. — Relationality. The events of nature are always interactions. All events of a system occur in relation to another system.
