Jean Baptiste Perrin

Jean Baptiste Perrin was a French physicist awarded the Nobel Prize in Physics in 1926 for his work on the atom's structure. He is best known for providing experimental evidence for the existence of atoms and molecules, helping to confirm the kinetic theory of matter. Perrin’s experiments demonstrated how light scattered by small particles could reveal their size, supporting the idea that matter is made up of tiny, discrete units. His research contributed significantly to atomic physics and paved the way for advancements in our understanding of matter and its properties.
