There are many different types of science in today's society. Some of these sciences include biology, chemistry, and physics. There are also topics within these topics. One of these topics is known as quantum physics. “Quantum physics is the theory that underlies almost all of our current understanding of the physical universe” (Rae xi). Without quantum physics, which we will call quantum mechanics, and some important quantum physicists, such as Max Planck, Niels Bohr, Erwin Schrödinger, Werner Heisenberg and Albert Einstein, especially many, if not all, things in quantum physics The universe would not be understood . Max Planck was one of the founders of quantum mechanics. He was born on April 23, 1858 in Kiel, Germany. He developed his interests in mathematics and physics when he was nine years old. Planck enrolled at the University of Munich in 1874, but three years later transferred to the University of Berlin to study physics. He obtained his doctorate in 1879. He started as a lecturer, then in 1885 he was assigned the position of associate professor at the University of Kiel. He was then a professor at the University of Berlin in 1889 and subsequently appointed full professor in 1892. He was recognized as a theoretical physicist before theoretical physics was fully recognized as a discipline in its own right (Barron par. 2-4). If it were not for Max Planck, quantum mechanics would not have been created, potentially. In 1900 he presented the law that led to quantum mechanics (Charap 3). There was a grave error in what physicists believed about the structure of an atom. This was demonstrated by Planck when he showed that as the electron moves around the nucleus, it accelerates. Because of this acceleration...... half of the document ......and Great Debate Over the Nature of Reality. New York: W. W. Norton & Company, Inc., 2008.
