Carl David Anderson

Carl David Anderson was an American physicist who made significant contributions to high-energy physics, particularly known for his discovery of the positron, the antiparticle of the electron, in 1932. Using a cloud chamber, he observed tracks from particles that contradicted existing theories, leading to the realization of antimatter. This groundbreaking discovery not only advanced our understanding of particle physics but also paved the way for further research into particle-antiparticle interactions, influencing both theoretical frameworks and practical applications in modern physics, including medical technologies like PET scans. Anderson's work earned him the Nobel Prize in Physics in 1936.
