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 ...

The development of quantum mechanics is attributed to several key scientists, each contributing foundational ideas that reshaped our understanding of the microscopic world. Max Planck is often regarded as the father of quantum theory. In 1900, Planck introduced the concept ...

The quantum model of the hydrogen atom was proposed by Niels Bohr in 1913. Bohr’s model was a significant advancement over previous atomic models, as it introduced the idea of quantized energy levels within an atom. Based on the work ...

The physicist who first proposed the nuclear model of the atom was Ernest Rutherford. In 1911, Rutherford conducted a series of experiments, known as the gold foil experiment, in which he directed alpha particles at a thin sheet of gold. ...

The famous scientist who discovered the law of gravitation was Sir Isaac Newton. In 1687, in his groundbreaking work Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), Newton formulated the law of universal gravitation. He proposed that every particle ...
