Pierre Léna
Pierre Léna, born on 22 November 1937 in Paris, is a French astrophysicist. He is a member of the French Academy of Sciences. In 1973, Léna was one of the scientists aboard the Concorde 001 during its flight in the shadow of a solar eclipse. Aboard, he conducted an experiment studying the F-corona (dust particles left over from comets in the sun's corona). Léna later published a book, ''Concorde 001 et l’ombre de la Lune'' (2015), about his experience with the flight.

1973 Eclipse Flight Of Concorde 001
On 30 June 1973, the supersonic jet Concorde 001 intercepted the path of a total solar eclipse and followed the path of totality as it crossed Africa. This feat allowed the passengers to experience a total solar eclipse for 74 minutes, the longest-ever total eclipse observation. Five experiments were carried out during the flight, but they have had limited scientific impact. Sequence of events Preparation and lead up In May 1972, Pierre Léna, an astronomer with the Paris Observatory, met with French Concorde test pilot André Turcat over lunch at a restaurant at Toulouse Airport to propose his idea to view the 1973 eclipse from an aircraft. Léna describes this meeting in his book about the project, ''Concorde 001 et l’ombre de la Lune'' (2015), while Turcat describes it in ''Un mythe éclipsé'' in ''Bulletin de l’Académie des sciences, agriculture, arts et belles lettres d’Aix-en-Provence'' (2013). British astrophysicist John Beckman had previously tried to ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Corona
A corona ( coronas or coronae) is the outermost layer of a star's atmosphere. It consists of plasma. The Sun's corona lies above the chromosphere and extends millions of kilometres into outer space. It is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. Spectroscopic measurements indicate strong ionization in the corona and a plasma temperature in excess of , much hotter than the surface of the Sun, known as the photosphere. The word ''corona'' is , in turn derived . History In 1724, French-Italian astronomer Giacomo F. Maraldi recognized that the aura visible during a solar eclipse belongs to the Sun, not to the Moon. In 1809, Spanish astronomer José Joaquín de Ferrer coined the term 'corona'. Based in his own observations of the 1806 solar eclipse at Kinderhook (New York), de Ferrer also proposed that the corona was part of the Sun and not of the Moon. English astronomer Norman Lockyer identified the first element unknown o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fernand Holweck Medal And Prize
The Fernand Holweck Medal and Prize is a major European prize for Physics awarded jointly every year by the British Institute of Physics (IOP) and the Société Française de Physique (SFP). It is one of the four Grand Prix of the SFP and one of the four International Bilateral Awards of the IOP, consisting of a gold medal and a 3000€ cash prize. History The prize was established in 1945 as a memorial to Fernand Holweck and other French physicists who were persecuted or killed by the Nazis during the German occupation of France during World War II, from 1940 to 1945. It was originally a £150 prize. It is awarded for distinguished work in experimental physics (which reflects Holweck's scientific interest) or in theoretical physics which is closely related to experimentation. The Holweck Prize is awarded every year, alternately to a French physicist and a British or Irish physicist. In 1974 two awards were made to mark the centenaries of the two societies.

Scientists From Paris
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''
