Enrico Fermi was an Italian-American physicist who created the world’s first nuclear reactor. He is widely known as the “architect of the nuclear age” and the “architect of the atomic bomb.” He won a Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment. He also made significant contributions in the field… Continue reading Enrico Fermi

As discussed before, Rutherford described an atom as consisting of a positive centre mass surrounded by orbiting electrons. Neils Bohr suspected that electrons revolved in quantized orbits. Having suspected this, Bohr worked on Rutherford’s model and proved that particles couldn’t occupy just any energy level.

Wilhelm Conrad Röntgen, a German physicist, produced and detected electromagnetic radiation in a wavelength range known as the X-rays. This discovery earned him a Nobel Prize in Physics.

During his work on electromagnetism, Heinrich reported another important phenomenon known as the Photoelectric effect. He noticed that UV rays made the metal lose charges faster than otherwise, which led him to publish his findings in the journal Annalen der Physik. He did not investigate this effect further on. Later, in 1905, Albert Einstein proposed that… Continue reading Heinrich Rudolf Hertz

Max Planck, a German Physicist, is best known for his proposition of the quantum theory of energy for which he was awarded the Nobel Prize. His work contributed significantly to the atomic and subatomic processes.

Marie Sklodowska-Curie was a chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize. She is most famous for the discovery of elements Polonium and Radium.

Henri Becquerel was a French physicist best known for his work on radioactivity for which he won a Nobel Prize. As a result, the SI unit of radioactivity Becquerel is named after him.

Thomas Edison made a lot of key inventions and discoveries. Here, we have listed a few noteworthy ones: Invented the carbon rheostat Discovered incandescent light Invented the motion picture camera Invented the fluorescent electric lamp Discovered Thermionic Emission Edison has been described as “America’s greatest inventor.” He developed many devices in fields like mass communication… Continue reading Thomas Edison

Faraday was a man devoted to discovery through experimentation. He was famous for never giving up on ideas that came from scientific intuition. When he thought of an idea, he would keep experimenting through multiple failures until he got what was expected. Below is the list of his few noteworthy discoveries: Discovery of Electromagnetic Induction Discovery… Continue reading Michael Faraday
