Carl D. Anderson

Carl D. Anderson was an American physicist known for his pioneering work in particle physics. In 1936, he discovered the positron, the antimatter counterpart of the electron, using a cloud chamber, which made it the first direct observation of antimatter. His work laid the groundwork for understanding fundamental particles and interactions in collider physics, where particles are accelerated and smashed together to reveal their subatomic components. Anderson's contributions significantly advanced the field and earned him the Nobel Prize in Physics in 1936, helping to deepen our understanding of the universe at the most fundamental level.
