Vasily Dokuchaev
Vasily Vasilyevich Dokuchaev (; 1 March 1846 – 8 November 1903) was a Russian geologist and geographer who is credited with laying the foundations of soil science. The Ukrainian city of Dokuchaievsk is named after him. Overview Vasily Vasilevich Dokuchaev is commonly regarded as the father of soil science, the study of soils in their natural setting. He developed soil science in Russia and was perhaps the first to conduct broad geographical investigations of different soil types. His contribution to science figuratively "put soils on the map". He introduced the idea that other variables could explain the geographical variations in soil type besides geological factors (parent material), such as climatic and topographic factors, and by the duration of pedogenesis (soil formation). He developed the very first soil classification, using these ideas as a starting point. His ideas were taken up by many soil scientists, including Hans Jenny. Dokuchaev's work on soil ...

Philosophical Transactions Of The Royal Society
''Philosophical Transactions of the Royal Society'' is a scientific journal published by the Royal Society. In its earliest days, it was a private venture of the Royal Society's secretary. It was established in 1665, making it the second journal in the world exclusively devoted to science, after the '' Journal des sçavans'', and therefore also the world's longest-running scientific journal. It became an official society publication in 1752. The use of the word ''philosophical'' in the title refers to natural philosophy, which was the equivalent of what would now be generally called ''science''. Current publication In 1887 the journal expanded and divided into two separate publications, one serving the physical sciences ('' Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences'') and the other focusing on the life sciences ('' Philosophical Transactions of the Royal Society B: Biological Sciences''). Both journals now publish theme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluid Mechanics
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasma (physics), plasmas) and the forces on them. Originally applied to water (hydromechanics), it found applications in a wide range of disciplines, including mechanical engineering, mechanical, aerospace engineering, aerospace, civil engineering, civil, chemical engineering, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology. It can be divided into ''fluid statics'', the study of various fluids at rest; and ''fluid dynamics'', the study of the effect of forces on fluid motion. It is a branch of ''continuum mechanics'', a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic. Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems a ...

Reynolds Number
In fluid dynamics, the Reynolds number () is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between Inertia, inertial and viscous forces. At low Reynolds numbers, flows tend to be dominated by laminar flow, laminar (sheet-like) flow, while at high Reynolds numbers, flows tend to be turbulence, turbulent. The turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to the overall direction of the flow (Eddy (fluid dynamics), eddy currents). These eddy currents begin to churn the flow, using up energy in the process, which for liquids increases the chances of cavitation. The Reynolds number has wide applications, ranging from liquid flow in a pipe to the passage of air over an aircraft wing. It is used to predict the transition from laminar–turbulent transition, laminar to turbulent flow and is used in the scaling of similar but different-sized fl ...

Osborne Reynolds
Osborne Reynolds (23 August 1842 – 21 February 1912) was an Irish-born British innovator in the understanding of fluid dynamics. Separately, his studies of heat transfer between solids and fluids brought improvements in boiler and condenser design. He spent his entire career at what is now the University of Manchester. Life Osborne Reynolds was born in Belfast and moved with his parents soon afterward to Dedham, Essex. His father, Reverend Osborne Reynolds, was a Fellow of Queens' College, Cambridge who worked as a school headmaster and clergyman, but was also a very able mathematician with a keen interest in mechanics. The father took out a number of patents for improvements to agricultural equipment, and the son credits him with being his chief teacher as a boy. Reynolds showed an early aptitude and liking for the study of mechanics. In his late teens, for the year before entering university, he went to work as an apprentice at the workshop of Edward Hayes, a well known s ...

Emil Kraepelin
Emil Wilhelm Georg Magnus Kraepelin (; ; 15 February 1856 – 7 October 1926) was a German psychiatrist. H. J. Eysenck's Encyclopedia of Psychology identifies him as the founder of modern scientific psychiatry, psychopharmacology and psychiatric genetics. Kraepelin believed the chief origin of psychiatric disease to be biological and genetic malfunction. His theories dominated psychiatry at the start of the 20th century and, despite the later psychodynamic influence of Sigmund Freud and his disciples, enjoyed a revival at century's end. While he proclaimed his own high clinical standards of gathering information "by means of expert analysis of individual cases", he also drew on reported observations of officials not trained in psychiatry. His textbooks do not contain detailed case histories of individuals but mosaic-like compilations of typical statements and behaviors from patients with a specific diagnosis. He has been described as "a scientific manager" and "a political ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Clouston (psychiatrist)
Sir Thomas Smith Clouston (22 April 1840 – 19 April 1915) was a Scottish psychiatrist. Life Clouston was the youngest of four sons of Robert Clouston (1786–1857) 3rd of Nisthouse, in the Birsay parish of Orkney, and his wife Janet (née Smith). The Cloustons descend from Havard Gunnason (fl. 1090), Chief Counsellor to Haakon, Earl of Orkney, and later became landed gentry taking their name from their estate, Clouston. Clouston was educated at Aberdeen Grammar School and the University of Edinburgh. Clouston qualified M.D.(Edinburgh) with a thesis on the nervous system of the lobster, supervised by John Goodsir. His early interest in insanity resulted in an apprenticeship with David Skae, the eminent Superintendent of the Royal Edinburgh Asylum. In 1863, Clouston was appointed superintendent of the Cumberland and Westmoreland Asylum (Garlands Hospital) in Carlisle; and in 1873, in succession to Skae, Superintendent of the new Royal Edinburgh Asylum, which had been set ...
