Who developed the theory of quantum mechanics?

Werner Heisenberg

Werner Heisenberg, a German physicist, played a crucial role in the development of quantum mechanics with his formulation of the uncertainty principle in 1927. This principle revolutionized physics by demonstrating that, at the atomic scale, it is impossible to precisely determine both the position and the velocity of a particle simultaneously. His work not only paved the way for new theories in quantum physics but also had significant implications for the philosophy of science. Heisenberg was awarded the Nobel Prize in Physics in 1932 for his contributions to quantum theory, marking a major milestone in our understanding of the universe at its most fundamental level.
