The beauty of uncertainty from "summary" of Seven Brief Lessons on Physics by Carlo Rovelli
In physics, we have come to appreciate the beauty that lies in the heart of uncertainty. Uncertainty is not a flaw or a weakness; it is a fundamental aspect of the universe that we inhabit. It is not a limitation of our knowledge, but rather a window into the true nature of reality. Quantum mechanics, the most successful theory we have for describing the behavior of particles at the smallest scales, is built upon this foundation of uncertainty. In the quantum world, particles do not have definite positions or velocities; instead, they exist in a state of superposition, where they can be in multiple places or states at once. This uncertainty may seem unsettling at first, but it is what gives rise to the rich tapestry of phenomena that we observe in the quantum realm. It allows particles to interact in complex ways, forming atoms, molecules, and ultimately the world around us. Without uncertainty, there would...
