Bill Planck

Bill Planck, also known as William Planck, is not a widely recognized figure in general knowledge contexts. However, the term “Planck” often refers to Max Planck, the German physicist celebrated for founding quantum theory, which revolutionized our understanding of atomic and subatomic processes. Quantum theory introduced concepts such as quantization of energy levels and the uncertainty principle, fundamentally changing physics.
