Introduction to Quantum Reality
While sitting on a beach after a long discussion about physics, Carlo Rovelli and his colleague Časlav Brukner reflected on the strange nature of the world. Despite the immense success of modern science, the underlying reality of the universe remains difficult to believe. For a long time, scientists assumed the world was made of simple particles moved by basic forces.
This classical view changed in 1925 when Werner Heisenberg traveled to the island of Helgoland. There, he developed a new mathematical framework called quantum theory to explain observations that older theories could not account for. This discovery started a massive scientific change that continues to shape our understanding of nature today.
Today, quantum theory explains the behavior of atoms, the light of stars, and the foundation for modern technology like computers. Even though it is used every day and has never been proven wrong, the theory remains deeply mysterious. It challenges the idea that objects move along set paths and instead describes the world using waves of probability.
The theory suggests that the universe is not made of separate, solid objects. Instead, reality is built entirely from the relationships between things. Understanding this requires a major shift in how people think about existence. While it can be unsettling to give up old certainties about a solid world, accepting this new view allows for a deeper understanding of how the universe actually functions.
