Bruno Rossi and the Cosmic Radiation

Bruno Rossi and the Cosmic Radiation

On April 13, 1905, Italian experimental physicist Bruno Benedetto Rossi was born. Rossi made major contributions to particle physics and the study of cosmic rays. He was one of the first to use rockets to study cosmic rays above the Earth‘s atmosphere. Finding X-rays from space he became the grandfather of high energy astrophysics, being largely responsible for starting X-ray astronomy, as well as the study of interplanetary plasma. “In any case,…

The Broughton Suspension Bridge and the Resonance Disaster

The Broughton Suspension Bridge and the Resonance Disaster

On April 12, 1831, the Broughton Suspension bridge collapsed, reportedly due to mechanical resonance induced by troops marching in step. But, also wind can be the cause for mechanical resonance which leads to disaster, such as for the Tacoma Narrows Bridge in 1940. But, also buildings can be affected, such as the 39-story shopping mall called the “Techno-Mart” in Seoul, Korea, that had to be evacuated because of people synchronously exercising Tae Bo. The…

Joseph Fourier and the Greenhouse Effect

Joseph Fourier and the Greenhouse Effect

On March 21, 1768, French mathematician and physicist Jean Baptiste Joseph du Fourier was born. He is probably best known for his work in thermodynamics, where he introduced the concept of the Fourier Analysis, named in honor after him. There, he claimed that every mathematical function of a variable can be expanded to a sum of sines of multiples of that variable. What people most likely don’t know is that Fourier also was the…

Frederick Reines’ Chase for the Ghost Particle

Frederick Reines’ Chase for the Ghost Particle

On March 16, 1918, American physicist and Nobel Laureate Frederick Reines was born. He is best known for his co-detection of the neutrino with Clyde Cowan in the neutrino experiment. The neutrino is a subatomic particle, a tiny lepton with little or no mass and a neutral charge which had been postulated by Wolfgang Pauli in the early 1930s but had previously remained undiscovered. Reines shared the Nobel Prize with physicist Martin…

George Gamow and his fundamental Views on the Foundations of Science

George Gamow and his fundamental Views on the Foundations of Science

On March 4, 1904, theoretical physicist and cosmologist George Gamow was born. He was an early advocate and developer of George Lemaître’s Big Bang theory. Besides his contributions to physics, in his middle and late career, Gamow focused more on teaching, and became well known as an author of popular books on science, which are still in print more than 50 years after their publication. “There was a young fellow from Trinity,…

Fritz Zwicky and the Existence of Dark Matter

Fritz Zwicky and the Existence of Dark Matter

On February 14, 1898, Swiss astronomer Fritz Zwicky was born. He is best known for his proposal of he existence of dark matter and counts as one of the most important astronomers of the 20th century. “To eliminate the discrepancy between men’s plans and the results achieved, a new approach is necessary. Morphological thinking suggests that this new approach cannot be realized through increased teaching of specialized knowledge. This morphological analysis suggests that the…

Leo Szilard and the Atomic Bomb

Leo Szilard and the Atomic Bomb

On February 11, 1898, Hungarian-American physicist and inventor Leo Szilard was born. He conceived the nuclear chain reaction in 1933, patented the idea of a nuclear reactor with Enrico Fermi, and in late 1939 together with Albert Einstein wrote the letter that resulted in the Manhattan Project that built the atomic bomb. He also conceived the electron microscope, the linear accelerator, and also the cyclotron. “A scientist’s aim in a discussion with his colleagues is not…

Dimitri Mendeleev and the Periodic Table of Elements

Dimitri Mendeleev and the Periodic Table of Elements

On February 2, 1907, Russian chemist and inventor Dimitri Ivanovich Mendeleev passed away. He is probably best known for his version of the periodic table of chemical elements. Furthermore, he used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered. “I wish to establish some sort of system not guided by chance but by some sort of definite…

Statistical Mechanics with Paul Ehrenfest

Statistical Mechanics with Paul Ehrenfest

On January 18, 1881, Austrian and Dutch theoretical physicist Paul Ehrenfest was born. Ehrenfest made major contributions to the field of statistical mechanics and its relations with quantum mechanics, including the theory of phase transition and the Ehrenfest theorem. “Einstein, my upset stomach hates your theory — it almost hates you yourself ! How am I to provide for my students ? What am I to answer to the philosophers ?” –…

Igor Kurchatov – Father of the Soviet Atomic Bomb

Igor Kurchatov – Father of the Soviet Atomic Bomb

On January 12, 1903, Soviet nuclear physicist and Nobel Laureate Igor Vasilyevich Kurchatov was born. Kurchatov is widely known as the director of the Soviet atomic bomb project and therefore often referred to as ‘Father of the Soviet Atomic Bomb‘. Igor Kurchatov – Youth and Education Igor Kurchatov was born in Simsky Zavod, Ufa Governorate (now the town of Sim, Chelyabinsk Oblast) in the family of a chartered surveyor and his mother a teacher.…
