Max Planck

Max Karl Ernst Ludwig Planck (April 23, 1858 – October 4, 1947) was a German theoretical physicist who is considered the founder of quantum mechanics, one of the most transformative scientific theories of the twentieth century. Born in Kiel, Germany, Planck studied physics and mathematics and eventually became a professor at the University of Berlin, where he conducted the research that would change physics forever. In 1900, while attempting to solve the problem of blackbody radiation (the energy distribution of electromagnetic radiation emitted by a perfect black body), Planck proposed a revolutionary idea: that energy is not continuous but comes in discrete packets called quanta (later termed photons). This proposal, embodied in his famous equation E=hν (where h is now called Planck's constant), contradicted classical Newtonian physics and opened the door to quantum mechanics. Though initially reluctant about his own theory's radical implications, Planck's work became the foundation upon which Einstein, Bohr, Heisenberg, and others built modern quantum theory. He won the Nobel Prize in Physics in 1918 for his discovery of energy quanta. Beyond his scientific contributions, Planck was a respected figure who witnessed and survived two World Wars, living through extraordinary historical upheaval while maintaining his commitment to physics. His legacy extends beyond his specific discoveries; Planck represents the power of theoretical thinking to revolutionize human understanding of the natural world.
