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…

Nicolas Sadi Carnot and the Science of Thermodynamics

Nicolas Sadi Carnot and the Science of Thermodynamics

Harald Sack
On June 1, 1796, French military engineer and physicist Nicolas Léonard Sadi Carnot was born. He is often described as the “father of thermodynamics“. In particular, Carnot gave the first successful theory of the maximum efficiency of heat engines. Carnot’s work attracted little attention during his lifetime, but it was later used by Rudolf Clausius and Lord Kelvin to formalize the second law of thermodynamics and define the concept of entropy. Carnot Background Sadi…

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…

Amedeo Avogadro – Relating Volumes to Quantities and Avogadro’s Law

Harald Sack
On August 9, 1776, Italian scientist Lorenzo Romano Amedeo Carlo Avogadro, Conte di Quaregna e Cerreto was born. He is most noted for his contribution to molecular theory now known as Avogadro’s law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules. In tribute to him, the number of elementary entities (atoms, molecules, ions or other particles) in 1 mole…
