Arthur Compton was born on September 10, 1892, and received the Nobel Prize in Physics in 1927 for demonstrating the particle-like nature of electromagnetic radiation. In his experiment, he directed X-rays onto a metallic surface and observed their behavior. He found that the X-rays lost some of their energy (or their wavelength increased) after colliding with the surface. This happened because part of the energy of the X-rays was transferred to the electrons in the material.

“What is the world made of?” Today, we answer: of atoms. The credit for this discovery is owed in part to John Dalton, who presented the first experimental evidence that elements and materials are composed of extremely small particles he called atoms.

The English chemist and physicist Frederick Soddy, born on September 2, 1877, was awarded the Nobel Prize in Chemistry in 1921 for his research on radioactive substances and the nature of isotopes.

The theoretical foundation of the blue glow observed in nuclear reactors known as the Cherenkov Effect was formulated by Igor Tamm, Nobel Prize in Physics, who was born on July 8, 1895.

Sir Isaac Newton published one of the most influential scientific works in history, Philosophiæ Naturalis Principia Mathematica ("The Principia").

Harriet Brooks was once compared to Marie Curie due to her scientific abilities and her pursuits in the field of nuclear physics. She was the first woman to work in nuclear physics in Canada and is well known for her contributions to the work of Ernest Rutherford, the Nobel Prize laureate widely regarded as the father of nuclear physics.

American physicist Martin Lewis Perl was born on June 24, 1927, and is considered one of the most prominent figures in the field of particle physics. He is best known for his discovery of a heavy lepton, later named the tau lepton (τ) — a breakthrough that played a pivotal role in understanding the third generation of subatomic particles within the Standard Model of particle physics.

Most people believe that the atomic nucleus is spherical in shape, but did you know that it’s actually not? The credit for uncovering this fact goes to the physicist Aage Bohr.

What does an atom look like? While this may seem like a theoretical question, Erwin Müller was the first to provide a real answer with actual images of individual atoms.

A portion of the credit for what scientists know today about electrons goes to the Thomson family. Sir George Thomson, who was born on this day, May 3, 1892, is renowned for discovering that electrons exhibit wave-like properties. His father, Joseph John Thomson, was the one who discovered the electrons themselves.
