The theory of relativity and quantum mechanics are complementary descriptions of reality from "summary" of Reality Is Not What It Seems by Carlo Rovelli
In the search for a unified description of reality, two major theories have emerged: the theory of relativity and quantum mechanics. These two theories, developed in the 20th century, have revolutionized our understanding of the universe. However, they seem to describe reality in fundamentally different ways. The theory of relativity, proposed by Albert Einstein, deals with the large-scale structure of the universe. It describes the nature of space and time, showing how they are intertwined in what we now call spacetime. On the other hand, quantum mechanics, developed by scientists like Niels Bohr and Werner Heisenberg, focuses on the behavior of matter and energy at the smallest scales, dealing with particles like electrons and photons. Despite their apparent differences, both theories have been incredibly successful in explaining a wide range of phenomena. The theory of relativity has allowed us to understand the behavi...
