Max Planck: Revolutionary Physicist (Mission: Science Biographies)

In the late 1800s, Max Planck’s teachers told him that science wasn’t worth studying because all the big questions had already been answered. Max Planck didn’t listen and went on to do groundbreaking research in physics, the science that studies matter and energy. His research into heat and how it moves led to his Nobel Prize-winning discovery of the quantum theory, which explains the movement inside atoms. It changed the way scientists understood the world. For more information on matter and energy, read Matter, another book in the Mission: Science series.
