The discovery of neutrons is credited to British physicist James Chadwick in 1932. Chadwick conducted a series of experiments in which he bombarded beryllium with alpha particles, leading to the emission of a neutral radiation. Through careful analysis, he concluded ...

The physicist associated with the concept of wave-particle duality is Louis de Broglie. In 1924, de Broglie proposed that particles, such as electrons, exhibit wave-like properties, just as light exhibits both wave and particle characteristics. He introduced the idea that ...

The physicist who first measured the charge on an electron experimentally was Robert A. Millikan. In 1909, Millikan conducted his famous oil drop experiment, in which he observed tiny oil droplets suspended in an electric field. By balancing the gravitational ...

The physicist who first confirmed the existence of positrons experimentally was Carl Anderson in 1932. Anderson was studying cosmic rays using a cloud chamber, a device that allowed him to observe the paths of charged particles. While investigating the particles ...

The concept of the antiparticle was first proposed by the British physicist Paul Dirac in 1928. Dirac developed an equation, known as the Dirac equation, to describe the behavior of relativistic electrons. In solving this equation, he discovered that it ...
