Robert Wilhelm Bunsen and the Bunsen Burner

Robert Wilhelm Bunsen and the Bunsen Burner

On March 30, 1811, German chemist Robert Wilhelm Bunsen was born. Bunsen investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.[6] He developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organoarsenic chemistry. With his laboratory assistant, Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use.…

Pierre Simon de Laplace and his true love for Astronomy and Mathematics

Pierre Simon de Laplace and his true love for Astronomy and Mathematics

On March 28, 1749, French mathematician and astronomer Pierre Simon marquis de Laplace was born, whose work was pivotal to the development of mathematical astronomy and statistics. One of his major achievements was the conclusion of the five-volume Mécanique Céleste (Celestial Mechanics) which translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. “One sees, from this Essay, that the theory of probabilities…

Wilhelm Conrad Röntgen – The Father of Diagnostic Radiology

Wilhelm Conrad Röntgen – The Father of Diagnostic Radiology

On March 27, 1845, Wilhelm Conrad Röntgen was born. The German physicist is best known for producing and detecting electromagnetic radiation in a wavelength range, better known as X-rays or Röntgen rays. Röntgen received the Nobel Prize in Physics for his achievement in 1901. “Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had…

Josef Stefan’s – Black Bodies and Thermodynamic Temperature

Josef Stefan’s – Black Bodies and Thermodynamic Temperature

On March 24, 1835, Carinthian Slovene physicist, mathematician, and poet Josef Stefan was born. Stefan is best known for originating Stefan’s law in 1879, a physical power law stating that the total radiation from a black body is proportional to the fourth power of its thermodynamic temperature T. As long as you are not a physicist specialized in black body radiation, you probably have never heard of Josef Stefan. For me as a computer…

Emmy Noether and the Love for Mathematics

Emmy Noether and the Love for Mathematics

On April 23, 1882, German mathematician and physicist Emmy Noether was born, who is best known for her groundbreaking contributions to abstract algebra and theoretical physics. Albert Einstein called her the most important woman in the history of mathematics, as she revolutionized the theories of rings, fields, and algebras. “My methods are really methods of working and thinking; this is why they have crept in everywhere anonymously.” Letter to Helmut Hasse (1931)…

Nathan Rosen – Wormholes and Time Travel

Nathan Rosen – Wormholes and Time Travel

On March 22, 1909, US-American physicist Nathan Rosen was born. He is best known for his cooperation together with Albert Einstein and Boris Podolsky on the quantum-mechanical description of physical reality leading the the so-called Einstein-Podolsky-Rosen paradoxon, as well as his postulation of worm holes connecting distant areas in space. Although purely theoretic, his work also had an important impact on science fiction literature. Early Years Nathan Rosen was born in New York City. He first…

Alessandro Volta and the Electricity

Alessandro Volta and the Electricity

On March 20, 1800, Italian physicist Alessandro Volta informed the British Royal Society in London about his newly invented electric power source, the Voltaic pile, the first energy source technology capable of producing a steady, continuous flow of electricity. “The language of experiment is more authoritative than any reasoning: facts can destroy our ratiocination—not vice versa. “ — Count Alessandro Giuseppe Antonio Anastasio Volta, Quoted in [12] First Experiments with Eletricity Alessandro…

How Albert Einstein Revolutionized Physics

How Albert Einstein Revolutionized Physics

On March 14, 1879, German theoretical physicist Albert Einstein was born, who has become an iconic figure for physics as well as science of the 20th century. He is best known for his theories on special and general relativity, as well as for the discovery of the photoelectric effect – for which he received the Nobel Prize – and he developed what has been named the most famous equation in history, the mass energy…

Augustin-Jean Fresnel and the Wave Theory of Light

Augustin-Jean Fresnel and the Wave Theory of Light

On March 10, 1788, French civil engineer and physicist Augustin-Jean Fresnel was born. Augustin-Jean Fresnel‘s research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Newton‘s corpuscular theory, from the late 1830s until the end of the 19th century. “It’s not observation but theory that led me to this result that experience has confirmed afterwards.” – Augustin-Jean Fresnel, explaining how he was led to…

Hans Christian Ørsted connecting Electricity and Magnetism

Hans Christian Ørsted connecting Electricity and Magnetism

On March 9, 1851, Danish physicist Hans Christian Ørsted passed away. Hans Christian Ørsted discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He is still known today for Oersted‘s Law and the oersted (Oe), the cgs unit of magnetic H-field strength, is named after him. “The agreement of this law with nature will be better seen by the repetition of experiments than by…
