Lord Kelvin. It is believed the "PNP" in his signature stands for "Professor of Natural Philosophy". Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin was an Irish mathematician, mathematical physicist and engineer. [7][8] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow ...
James Joule was born in 1818, the son of Benjamin Joule (1784–1858), a wealthy brewer, and his wife, Alice Prescott, on New Bailey Street in Salford. [3] Joule was tutored as a young man by the famous scientist John Dalton and was strongly influenced by chemist William Henry and Manchester engineers Peter Ewart and Eaton Hodgkinson.
Attempts to unify those models or to create a complete mechanical description of them did not succeed, [3] but after considerable work by many scientists, including Michael Faraday [4] [5] and Lord Kelvin, James Clerk Maxwell (1864) developed an accurate theory of electromagnetism by deriving a set of equations in electricity, magnetism and ...
Preceded by. J. J. Thomson. Succeeded by. Lawrence Bragg. Signature. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM , FRS , HonFRSE [ 7 ] (30 August 1871 – 19 October 1937), was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. He has been described as "the father of nuclear physics", [ 8 ] and ...
Notable critics included Simon Newcomb, Lord Kelvin, and the chief engineer of the US Navy, George W. Melville, the latter of whom described flying machines as "wholly unwarranted, if not absurd". [4] After five years of preparations, aviation pioneer Samuel Langley was ready to test out his Aerodrome on October 7, 1903.
Lord Rayleigh. Signature. James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist with broad interests [ 1 ][ 2 ] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
Olbers's paradox, also known as the dark night paradox or Olbers and Cheseaux's paradox, is an argument in astrophysics and physical cosmology that says that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. In the hypothetical case that the universe is static, homogeneous at a large scale ...
Born in Paris on 15 May 1859, Pierre Curie was the son of Eugène Curie (1827–1910), a doctor of French Huguenot Protestant origin from Alsace, and Sophie-Claire Curie (née Depouilly; 1832–1897). He was educated by his father and in his early teens showed a strong aptitude for mathematics and geometry. When he was 16, he earned his ...
