Georges Lemaître and the Origins of the Big Bang Theory

Georges Lemaître and the Origins of the Big Bang Theory

On June 20, 1966, Belgian priest, astronomer and professor of physics Georges Lemaître passed away. He was the first person to propose the theory of the expansion of the Universe, widely misattributed to Edwin Hubble, and is best known for his proposal of what became known as the Big Bang theory of the origin of the Universe. “We want a fireworks theory of evolution. The last two thousand million years are slow…

Sir Fred Hoyle – How Big Bang Theory’s Most Eager Opponent was Responsible for its Popularity

Sir Fred Hoyle – How Big Bang Theory’s Most Eager Opponent was Responsible for its Popularity

On August 20, 2001, famous astronomer, mathematician, and author Sir Fred Hoyle passed away. The scientist was the first to coin the term “Big Bang” for the now prevailing theory of the early development of the universe in 1949, even though he happened to be a strong opponent of this theory. “We now come to the question of applying the observational tests to earlier theories. These theories were based on the hypothesis that all…

James Jeans and the Theory of Continuous Creation

James Jeans and the Theory of Continuous Creation

On September 11, 1877, English physicist, astronomer and mathematician James Hopwood Jeans was born. Jeans was the first to propose that matter is continuously created throughout the universe. He made other innovations in astronomical theory but is perhaps best known as a writer of popular books about astronomy. “The stream of knowledge is heading towards a non-mechanical reality; the Universe begins to look more like a great thought than like a great machine.…

Hannes Alfvén – the Father of Plasma Physics

Hannes Alfvén – the Father of Plasma Physics

On May 30, 1908. Swedish electrical engineer, plasma physicist, and Nobel laureate Hannes Alfvén was born. Alfvén won the 1970 Nobel Prize in Physics for his work on magnetohydrodynamics (MHD). He described the class of MHD waves now known as Alfvén waves. Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth’s magnetic field, the terrestrial magnetosphere, and the dynamics…

Robert Hofstadter and controlled Nuclear Fission

Robert Hofstadter and controlled Nuclear Fission

On February 5, 1915, American physicist Robert Hofstadter was born. He was the joint winner of the 1961 Nobel Prize in Physics (together with Rudolf Mössbauer) “for his pioneering studies of electron scattering in atomic nuclei and for his consequent discoveries concerning the structure of nucleons“. He revealed the hitherto unknown structure of these particles and helped create an identifying order for subatomic particles. He also correctly predicted the existence of the…

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. Gamow was born in Odessa, Russian Empire…
