Quantum Reality

At the heart of modern physics lies a world so strange it challenges everything we think we know about reality. QUANTUM MECHANICS is the branch of physics that describes how the universe behaves at the smallest possible scales — the level of atoms and the particles inside them. Unlike the everyday world we experience, the quantum world does not follow the familiar rules of classical physics, where objects have definite positions and predictable trajectories. Instead, particles at this scale exist in states that seem genuinely AMBIGUOUS until the moment they are measured or observed. This was not a comfortable idea for physicists, and it launched more than a century of passionate debate among the greatest scientific minds in history. The Copenhagen INTERPRETATION, proposed in the 1920s by Niels Bohr and Werner Heisenberg, was the first major attempt to make sense of these bewildering experimental results.
