August Seebeck
August Ludwig Friedrich Wilhelm Seebeck (27 December 1805 in Jena – 19 March 1849 in Dresden) was a scientist at the Technische Universität Dresden. Seebeck is primarily remembered for his work on sound and hearing, in particular with experiments with an acoustic siren that demonstrated that the pitch of a tone did not depend on the tone having a fundamental frequency component of the pitch frequency. His observations and theories are now highly regarded, but historically suffered in the battle with Ohm and Helmholtz, who took a Fourier analysis view of the sound of tones. With respect to Ohm's acoustic law, historians have concluded that Seebeck "successfully discredited the hypothesis and forced Ohm to withdraw from the field." See also *Auditory science *Sound localization *Temporal theory (hearing) The temporal theory of hearing states that human perception of sound depends on temporal patterns with which neurons respond to sound in the cochlea.

Nicholas F
Nicholas is a male given name and a surname. The Eastern Orthodox Church, the Roman Catholic Church, and the Anglican Churches celebrate Saint Nicholas every year on December 6, which is the name day for "Nicholas". In Greece, the name and its derivatives are especially popular in maritime regions, as St. Nicholas is considered the protector saint of seafarers. Origins The name is derived from the Greek name Νικόλαος (''Nikolaos''), understood to mean 'victory of the people', being a compound of νίκη ''nikē'' 'victory' and λαός ''laos'' 'people'.. An ancient paretymology of the latter is that originates from λᾶς ''las'' ( contracted form of λᾶας ''laas'') meaning 'stone' or 'rock', as in Greek mythology, Deucalion and Pyrrha recreated the people after they had vanished in a catastrophic deluge, by throwing stones behind their shoulders while they kept marching on. The name became popular through Saint Nicholas, Bishop of Myra in Lycia, the inspirati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Johann Seebeck
Thomas Johann Seebeck (; 9 April 1770 – 10 December 1831) was a Baltic German physicist, who, in 1822, observed a relationship between heat and magnetism. Later, in 1823, Ørsted called this phenomenon thermoelectric effect. Seebeck was born in Reval (today Tallinn) to a wealthy Baltic German merchant family. He received a medical degree in 1802 from the University of Göttingen, but preferred to study physics. From 1821 to 1823, Seebeck performed a series of experiments trying to understand Ørsted's findings from 1820. During his experiments, he observed that a junction of dissimilar metals produces a deflexion on a magnetic needle (compass) when exposed to a temperature gradient. Because Ørsted had discovered that an electric current produces a deflexion on a compass transversal to the wire, Seebeck's results were interpreted as a thermoelectric effect. This is now called the Peltier–Seebeck effect and is the basis of thermocouples and thermopiles. Seebeck effect In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seebeck Effect
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side. This effect can be used to generate electricity, measure temperature or change the temperature of objects. Because the direction of heating and cooling is affected by the applied voltage, thermoelectric devices can be used as temperature controllers. The term "thermoelectric effect" encompasses three separately identified effects: the Seebeck effect, Peltier effect, and Thomson effect. The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
