Louis de Broglie’s Career and Contribution to ScienceJune 27, 2021
After a long period of experimenting together in his brother Maurice’s homemade atomic physics laboratory, it was Louis de Broglie’s doctoral dissertation published in 1924 that essentially shook the world of physics.
In this thesis titled Recherches sur la théoriedesquanta (Research on Quantum Theory), Broglie claimed the wave nature of electrons and proposed the part-wave duality. So much so that, according to Broglie, a particle always followed a wave.
Until these discoveries of Broglie, electrons were viewed only as moving particles. With this research, it has been observed that particles sometimes behave as particles and sometimes as waves in terms of their physical properties. Therefore, it is also called “duality” or “duality” or “dualism”.
Louis de Broglie’s theory postulates that every moving particle or object will also be associated with a wave. Although Broglie did not develop his theory based on experimentation, Albert Einstein, who was aware of the theory, also supported Broglie’s theory. So much so that the experimental proof of this radical theory took place in 1927. The scientists who helped to prove the theory in question experimentally are Lester Germer and Clinton Davisson. Due to all these developments, the research known as the Broglie Hypothesis has also led to the birth of wave mechanics studies, which is one of the fundamental fields of physics today.
For this discovery, Louis de Broglie won the Nobel Prize in Physics in 1929. After earning his doctorate in physics at Sorbonne University, he continued his academic life as a professor in the field of theoretical physics at the same university. Louis de Broglie continued his academic life in this position until his retirement in 1962.
