Sir George Stokes and Fluid Dynamics

Sir George Stokes and Fluid Dynamics

Harald Sack
On February 1, 1903, Irish mathematician, physicist, politician and theologian Sir George Gabriel Stokes, 1st Baronet, passed away. Stokes made seminal contributions to fluid dynamics, optics, and mathematical physics including the first version of what is now known as Stokes’ theorem. “It is very difficult for us, placed as we have been from earliest childhood in a condition of training, to say what would have been our feelings had such training never…

Lord Kelvin and the Analysis of Thermodynamics

Lord Kelvin and the Analysis of Thermodynamics

Harald Sack
On December 17, 1907, Irish physicist William Thomson, 1st Baron Kelvin of Largs, passed away. Thomson did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics. Absolute temperatures are stated in units of kelvin in his honour. He was ennobled in 1892 in recognition of his achievements in thermodynamics. Go, wondrous creature! mount where Science guides; Go measure earth, weigh air, and state…

James Clerk Maxwell and the Electromagnetic Fields

James Clerk Maxwell and the Electromagnetic Fields

Tabea Tietz
On June 13, 1831, Scottish physicist James Clerk Maxwell was born. His most prominent achievement was formulating a set of equations that united previously unrelated observations, experiments, and equations of electricity, magnetism, and optics into a consistent theory. According to his theory he has demonstrated that electricity, magnetism and light are all manifestations of the same phenomenon, namely the electromagnetic field. This has been called the “second great unification in physics”, after the…

A Life of Discoveries – the great Michael Faraday

A Life of Discoveries – the great Michael Faraday

Tabea Tietz
On September 22, 1791, the famous chemist and physicist Michael Faraday  was born. He is responsible for the discovery of the electromagnetic induction, the laws of electrolysis and best known for his inventions, which laid the foundations to the electrical industry. But, to understand the person and the scientist Michael Faraday, we have to look a little bit into his background and his development. “I was at first almost frightened when I…

Robert Alexander Watson-Watt and the Radar Technology

Robert Alexander Watson-Watt and the Radar Technology

Harald Sack
On February 26, 1935, British engineer and Fellow of the Royal Society Robert Alexander Watson-Watt started with first experiments on detecting and locating aircrafts with radio technique, later called ‘RADAR‘. Radar was initially nameless and researched elsewhere but it was greatly expanded on 1 September 1936 when Watson-Watt became Superintendent of Bawdsey Research Station located in Bawdsey Manor, near Felixstowe, Suffolk. Work there resulted in the design and installation of aircraft detection and tracking stations…

André-Marie Ampère and Electromagnetism

André-Marie Ampère and Electromagnetism

Tabea Tietz
On January 20, 1775, French physicist and mathematician André-Marie Ampère was born, after whom the unit of measurement of electric current, the ampere, is named. He is generally considered as one of the main founders of the science of classical electromagnetism, which he referred to as “electrodynamics“. A Child Prodigy André-Maria Ampère was born into a well educated family and influenced by the theories of Jean-Jacques Rousseau early. He was home schooled by his…

Heinrich Hertz and the Successful Transmission of Electromagnetic Waves

Heinrich Hertz and the Successful Transmission of Electromagnetic Waves

Tabea Tietz
On November 13, 1886, German physicist Heinrich Hertz succeeded to transmit electromagnetic waves from a sender to a receiver in Karlsruhe. Hertz conclusively proved the existence of the electromagnetic waves theorized by James Clerk Maxwell’s electromagnetic theory of light.[4] The unit of frequency – cycle per second – was named the “hertz” in his honor. “The rigour of science requires that we distinguish well the undraped figure of Nature itself from the gay-coloured…

John William Strutt and the Rayleigh Scattering

John William Strutt and the Rayleigh Scattering

Harald Sack
On November 12, 1842, English physicist John William Strutt, 3rd Baron Rayleigh was born. Rayleigh with William Ramsay, discovered argon, an achievement for which he earned the Nobel Prize for Physics in 1904. He also discovered the phenomenon now called Rayleigh scattering, which can be used to explain why the sky is blue, and predicted the existence of the surface waves now known as Rayleigh waves. Education and the Theory of Sound…

James Edward Keeler and the Rings of Saturn

Harald Sack
On September 10, 1857, American astronomer James Edward Keeler was born. Keeler is best known for being the astronomer who confirmed James Clerk Maxwell‘s theory that the rings of Saturn were not solid (requiring uniform rotation), but composed of meteoric particles.[3] James Edward Keeler – Early Years James Edward Keeler was born in La Salle, Illinois, to William F. Keeler, who served as a paymaster in the U.S. Navy at the time…

Oliver Heaviside changed the Face of Telecommunications

Tabea Tietz
On May 18, 1850, English self-taught electrical engineer, mathematician, and physicist Oliver Heaviside was born. Heaviside adapted complex numbers to the study of electrical circuits, invented mathematical techniques for the solution of differential equations, reformulated Maxwell’s field equations in terms of electric and magnetic forces and energy flux, and independently co-formulated vector analysis. “However absurd it may seem, I do in all seriousness hereby declare that I am animated mainly by philanthropic motives.…
