Picture of Max Planck
Max Planck was a German physicist who lived between 1858-1947. His theories revolutionized our understanding of atomic processes and originated the field of quantum physics, which studies energy inside atoms.
Planck's study of radiant energy, such as light, showed that energy is quantized, meaning it can't be infinitely small. This result was later used by Einstein when he developed his theory of relativity.
Planck believed that the physical universe exists independently of humans and that we have no control over the laws of nature. He claimed that we can observe and try to understand such laws, but we can't change them.
