The year 1834 in science and technology included many events, some of which are listed here.
1 Astronomy
2 Biology
- James Paget discovers in human muscle the parasitic worm that causes trichinosis
- Félix Dujardin proposes that single-cell animals should be classified in a group by themselves
3 Geology
- The Triassic is named by Friedrich August von Alberti for the three distinct layers of redbeds, capped by chalkChalk is a soft, white, porous form of limestone composed of the mineral calcium carbonate. It is relatively resistant to erosion and slumping compared to the clays that it is usually associated with, and so forms tall steep cliffs where chalk ridges meet, followed by black shaleShale is a fine-grained sedimentary rock whose original constituents were clays or muds. It is characterized by thin laminae breaking with an irregular curving fracture, often splintery, and parallel to the often indistinguishable bedding planes. Non-fisss that are found throughout GermanyThe Federal Republic of Germany ( German: Bundesrepublik Deutschland is one of the world's leading industrialized countries, located in the middle of the European Union. It is bordered to the north by the North Sea, Denmark and the Baltic Sea, to the east and Northwest EuropeFor the band of the same name, see Europe (band . Europe is a continent forming the westermost part of the Eurasian supercontinent. Europe is bounded to the north by the Arctic Ocean, to the west by the Atlantic Ocean, to the south by the Mediterranean Se, called the 'Trias'
4 Mechanics
- Carl Gustav Jakob JacobiKarl Gustav Jacob Jacobi ( Potsdam December 10, 1804 Berlin February 18, 1851), was not only a great German mathematician but also considered by many as the most inspiring teacher of his time (Bell, p. 330) He was born of Jewish parentage in 1804. He stud discovers his uniformly rotating self-gravitating ellipsoidDefinition In mathematics, an ellipsoid is a type of quadric that is a higher dimensional analogue of an ellipse. The equation of a standard ellipsoid in an x ''y ''z Cartesian coordinate system is : where a b and c are fixed positive real numbers determis
- John Scott RussellJohn Scott Russell ( May 9 1808- 8 June 1882) was a Naval Engineer who built The Great Eastern in collaboration with Isambard Kingdom Brunel, and made the discovery that gave birth to the modern study of Solitons. Early Life Russell was born in Glasgow, S observes a nondecaying solitary water wave ( solitonA soliton is a self-reinforcing solitary wave caused by nonlinear effects in the medium. Solitons are found in many nonlinear physical phenomena, as they are found as solutions of many different nonlinear differential equations. The soliton phenomenon was) in the Union Canal near Edinburgh and uses a water tank to study the dependence of solitary water wave velocities on wave amplitude and water depth
