John Dollond – Improving the Telescope with Achromatic Lenses

John Dollond – Improving the Telescope with Achromatic Lenses

On June 10, 1706 (10 June O.S. / 21 June N.S.), English optician John Dollond was born. He is known for his successful optics business and his patenting and commercialization of achromatic lenses. John Dolland Background John Dollond came from a Huguenot emigrant family and initially worked as a silk weaver like everyone else in his family, but was also involved in astronomy and optics. He studied Latin, Greek, mathematics, physics, and anatomy…

The Holographic World of Dennis Gabor

The Holographic World of Dennis Gabor

On June 5, 1900, Hungarian-British electrical engineer and physicist Dennis Gabor was born. He is probably best known for inventing holography, for which he later received the 1971 Nobel Prize in Physics. Holography is a system of lensless, three-dimensional photography that has many applications today. Gabor also did research on high-speed oscilloscopes, communication theory, physical optics, and television. Overall, he held more than 100 patents. “Incomplete knowledge of the future, and also of…

James Pollard Espy – the Storm King

James Pollard Espy – the Storm King

On May 9, 1785, U.S. Meteorologist James Pollard Espy was born. Espy developed a convection theory of storms and developed the use of the telegraph in assembling weather observation data by which he studied the progress of storms and laid the basis for scientific weather forecasting. James Pollard Espy – Early Years The youngest of ten children, James Espy was born in Westmoreland County, Pennsylvania, USA. He had an ardent desire for…

Heinrich Gustav Magnus and the Magnus Effect

Heinrich Gustav Magnus and the Magnus Effect

On May 2, 1802, German physicist Heinrich Gustav Magnus was born. He is best known for the Magnus effect (the lift force produced by a rotating cylinder, which for example, gives the curve to a curve ball). In chemical research, he discovered the first of the platino-ammonium compounds compounds. Heinrich Gustav Magnus – Early Years Heinrich Gustav Magnus’ father, the wealthy cloth and silk merchant Immanuel Meyer Magnus was baptized in 1807 with…

Jan Hendrik Oort and the Secrets of the Oort Cloud

On April 28, 1900, Dutch physicist and astronomer Jan Hendrik Oort was born. One of the greatest astronomers of the 20th century, Oort made significant contributions to the understanding of the Milky Way and who was a pioneer in the field of radio astronomy. Oort determined that the Milky Way rotates and overturned the idea that the sun is at its center; he discovered mysterious invisible ‘dark matter‘ in 1932, as well…

Sin-Itiro Tomonaga and Quantum Electrodynamics

Sin-Itiro Tomonaga and Quantum Electrodynamics

On March 31, 1906, Japanese physicist and Nobel laureate Sin-Itiro Tomonaga was born. He was influential in the development of quantum electrodynamics, work for which he was jointly awarded the Nobel Prize in Physics in 1965 along with Richard Feynman and Julian Schwinger. Tomonaga was one of the first to apply quantum theory to subatomic particles with very high energies. “Nature was not satisfied by a simple point charge but required a…

Sir George Stokes and Fluid Dynamics

Sir George Stokes and Fluid Dynamics

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…

John Michell and the Effect of Gravity on Light

John Michell and the Effect of Gravity on Light

On December 25, 1724, English natural philosopher and geologist John Michell was (probably) born. He is best known as both a theorist and an experimenter, who was the first to propose the effects of gravity on light, later resulting in the physics of general relativity and black holes. John Michell was born in Nottinghamshire, however, his exact birth place and date remain unknown. He earned his Master’s degree drom Queen’s College of…

Maria Telkes and the Power of the Sun

On December 12, 1900, Hungarian–American scientist and inventor Mária Telkes was born. She is best known for her work in solar energy technology. Mária Telkes finished her dissertation in the field of physical chemistry in 1924 at the University o Budapest and moved to the united States shortly after. About one year later, Telkes accepted a position as a biophysicist for the Cleveland Clinic Foundation, where she researched on creating a photoelectric…

Anders Celsius and the Celsius Scale of Temperature

Anders Celsius and the Celsius Scale of Temperature

On November 27, 1701, Swedish astronomer, physicist and mathematician Anders Celsius was born. He is famous for the temperature scale he developed and which is named after him. Besides the U.S. that measures temperature according to the scale developed by Fahrenheit, Celsius’ original scale was adopted as the international standard and is still used in almost all scientific work. Anders Celsius was the son of an astronomy professor and completed his education near Stockholm.…
