### Albert Einstein

Albert Einstein revolutionized physics with his theory of relativity, including his special theory presented in 1905 and general theory in 1915. The special theory of relativity introduced the famous equation 2*E*=*mc*², showing the equivalence of mass and energy. His general theory of relativity redefined gravity as the curvature of spacetime caused by mass and energy, vastly different from Newton’s gravitational laws. These concepts not only expanded the understanding of the universe but also paved the way for modern physics.

### J.J. Thomson

In 1897, J.J. Thomson discovered the electron through his experiments with cathode rays. This was a pivotal moment in science, as it marked the first identification of a subatomic particle. Thomson’s work opened the door to the modern era of atomic physics by proving that atoms could be divided into smaller parts, fundamentally changing the classical view that atoms were indivisible.

### Ernest Rutherford

Ernest Rutherford is best known for his development of the nuclear model of the atom in 1911. He demonstrated that an atom’s mass is concentrated in a small central nucleus, surrounded by orbiting electrons, through his gold foil experiment. This model corrected earlier atomic models and introduced the concept of a nuclear atom, which has had profound implications for both theoretical and applied physics.

### John Dalton

In the early 19th century, John Dalton proposed the atomic theory, which stated that all matter is composed of atoms, indivisible and indestructible particles. This theory also suggested that all atoms of a specific element are identical in weight and properties. Dalton’s atomic theory laid the groundwork for modern chemistry by explaining the composition and reactions of elements based on the behavior of atoms.

### James Chadwick

James Chadwick discovered the neutron in 1932, a neutral particle within the atomic nucleus that, along with protons, makes up the mass of the atom. The discovery of the neutron was crucial for the advancement of nuclear physics and technology, including nuclear power and weapons, as it explained the previously unclear extra mass and stability of the nucleus.

### Isaac Newton

Isaac Newton formulated the laws of motion and universal gravitation around 1687, which described the motion of objects at both everyday and cosmic scales. His mathematical principles of natural philosophy (“Principia Mathematica”) established the framework for classical mechanics, guiding the scientific revolution and dominating scientists’ view of the physical universe for the next three centuries.

### Charles-Augustin de Coulomb

Charles-Augustin de Coulomb formulated Coulomb’s Law in 1785, which describes the force between two charges. It states that the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. Coulomb’s law was a fundamental discovery that contributed to the development of the theory of electromagnetism.

### Georg Simon Ohm

In 1827, Georg Simon Ohm discovered Ohm’s Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. This fundamental principle in electrical circuits underpins much of contemporary electrical engineering and technology.

### Michael Faraday

Michael Faraday’s discovery of electromagnetic induction in 1831 laid the groundwork for the electric transformer and generator. His discovery that a changing magnetic field produces an electric field has had vast implications and led to the development of electrical technology.

### Thomas Edison

Thomas Edison’s significant contribution was the development of a practical electric light bulb in 1879. His improvements, including a durable incandescent material and a higher vacuum inside the bulb, made the widespread use of electric light feasible.

### Henri Becquerel

Henri Becquerel stumbled upon radioactivity in 1896 while researching the properties of X-rays. His discovery that uranium salts emitted radiation without any external source of energy introduced the concept of radioactivity, profoundly affecting scientific directions in physics and chemistry.

### Marie Sklodowska-Curie

Marie Curie, alongside her husband Pierre, discovered the radioactive elements polonium and radium in 1898. Her research into radioactivity, a term she coined, led to significant developments in the understanding of atomic science and had broad implications in medicine and industry.

### Max Planck

Max Planck, the father of quantum theory, introduced the concept in 1900, proposing that energy is emitted in discrete units or quanta. His theory reshaped the foundations of physics, influencing the development of various modern scientific fields.

### Heinrich Rudolf Hertz

In 1888, Heinrich Rudolf Hertz demonstrated the existence of electromagnetic waves, confirming James Clerk Maxwell’s theories and paving the way for the development of modern communication technology, including radio and television.

### Wilhelm Conrad Röntgen

Wilhelm Conrad Röntgen discovered X-rays in 1895, a type of electromagnetic radiation that has become indispensable in medical imaging. This discovery, which earned him the first Nobel Prize in Physics, has had a lasting impact on medical diagnostics.

### Niels Bohr & Ernest Rutherford

Expanding on Rutherford’s findings, Niels Bohr developed the Bohr model of the atom in 1913, introducing the concept of electrons in discrete orbital levels. This model was fundamental in the early development of quantum mechanics and atomic physics.

### Enrico Fermi

Enrico Fermi’s creation of the first nuclear reactor in 1942 marked a pivotal moment in scientific history. This achievement demonstrated a controlled nuclear chain reaction, leading to the development of nuclear power and atomic weaponry, impacting global energy strategies and international relations.
