August Krogh and the Capillaries

On November 15, 1874, Danish zoophysiologist August Krogh was born. Krogh contributed a number of fundamental discoveries within several fields of physiology, and is famous for developing the Krogh Principle, which states that “for such a large number of problems there will be some animal of choice, or a few such animals, on which it can be most conveniently studied.” In 1920 August Krogh was awarded the Nobel Prize in Physiology or…
Heinrich Hertz and the Transmission of Electromagnetic Waves

Heinrich Hertz and the Transmission of Electromagnetic Waves

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. The unit of frequency – cycle per second – was named the “hertz” in his honor. Heinrich Hertz studied science and engineering in Dresden, Munich, and Berlin under Gustav R. Kirchhoff and…

Joseph G. Hamilton and the health effects of radioactive isotopes

On November 11, 1907, American professor of Medical Physics, Experimental Medicine, General Medicine, and Experimental Radiology Joseph Gilbert Hamilton was born. Hamilton studied the medical effects of exposure to radioactive isotopes, which also included the use of unsuspecting human subjects. Joseph Hamilton joined the University of California and earned his Bachelors degree in Chemistry in 1929. He continued his education and studied medicine in Berkeley and also worked at the University…

J. B. S. Haldane and population Genetics

On November 5, 1892, English geneticist and biometrician John Burdon Sanderson Haldane was born. Haldane is known for his work in the study of physiology, genetics, evolutionary biology, and in mathematics, where he made innovative contributions to the fields of statistics and biostatistics. John Burdon Sanderson Haldane began working with hos father in the home laboratory. There, he performed first experiments, mostly on himself. At New College at the University…
Eugen Warming and Ecology

Eugen Warming and Ecology

On November 3, 1841, Danish botanist Eugen Warming was born. Warming ia considered a main founding figure of the scientific discipline of ecology. He wrote the first textbook on plant ecology in 1895, taught the first university course in ecology and gave the concept its meaning and content. Eugen Warming attended the University of Copenhagen. However, he left the university in order to work with the Danish palaeontologist Peter Wilhelm Lund,…
Sir Hermann Bondi and the Steady State Theory

Sir Hermann Bondi and the Steady State Theory

On November 1, 1919, Anglo-Austrian mathematician and cosmologist Sir Herman Bondi was born. Bondi is best known for developing the Steady State theory of the universe with Fred Hoyle and Thomas Gold as an alternative to the Big Bang theory. Their model was rendered obsolete, when in 1965, Arno Penzias and Robert Wilson detected a background microwave radiation from all directions in space, as predicted by the “Big Bang” theory…
