Félix Savart ( /səˈvɑːr/ ; [1] French:  [savaʁ] ; 30 June 1791, Mézières 16 March 1841, Paris) was a physicist, mathematician who is primarily known for the Biot–Savart law of electromagnetism, which he discovered together with his colleague Jean-Baptiste Biot. His main interest was in acoustics and the study of vibrating bodies. [2] A particular interest in the violin led him to create an experimental trapezoidal model. He gave his name to the savart, a unit of measurement for musical intervals, and to Savart's wheel—a device he used while investigating the range of human hearing.

Physicist scientist who does research in physics

A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of physical phenomena and the analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies.

Mathematician person with an extensive knowledge of mathematics

A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems.

Biography

He was the son of Gérard Savart, an engineer at the military school of Metz. His brother, Nicolas, who was a student at the École Polytechnique and an officer in the engineering corps, did work on vibration. At the military hospital at Metz, Savart studied medicine and later he went on to continue his studies at the University of Strasbourg, where he received his medical degree in 1816. [3] Savart became a professor at Collège de France in 1836 and was the co-originator of the Biot–Savart law, along with Jean-Baptiste Biot. Together, they worked on the theory of magnetism and electrical currents. Their law was developed and published in 1820. [4] The Biot–Savart law relates magnetic fields to the currents which are their sources.

École Polytechnique French institution of higher education and research in Palaiseau

École polytechnique is a French public institution of higher education and research in Palaiseau, a suburb southwest of Paris. It is one of the most prestigious and selective French scientific and engineering schools, called grandes écoles in French. It is known for its ingénieur polytechnicien scientific degree program which is equivalent to both a bachelor and master of science. Its entrance exam, the X-ENS exam, is renowned for its selectivity with a little over 500 admitted students out of the 53 848 students enrolled in the preparatory programs for the French scientific and engineering schools entrance exams.

University of Strasbourg university in France (from 2009)

The University of Strasbourg in Strasbourg, Alsace, France, is a university in France with nearly 51,000 students and over 3,200 researchers.

Collège de France Higher education and research establishment

The Collège de France, founded in 1530, is a higher education and research establishment in France. It is located in Paris, in the 5th arrondissement, or Latin Quarter, across the street from the historical campus of La Sorbonne.

Savart also studied acoustics. He developed the Savart wheel which produces sound at specific graduated frequencies using rotating disks.

Acoustics science that deals with the study of all mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound and infrasound

Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.

Savart wheel

The Savart wheel is an acoustical device named after the French physicist Félix Savart (1791–1841), which was originally conceived and developed by the English scientist Robert Hooke (1635–1703).

Félix Savart is the namesake of a unit of measurement for musical intervals, the savart, though it was actually invented by Joseph Sauveur (Stigler's law of eponymy).

Joseph Sauveur was a French mathematician and physicist. He was a professor of mathematics and in 1696 became a member of the French Academy of Sciences.

Stigler's law of eponymy, proposed by University of Chicago statistics professor Stephen Stigler in his 1980 publication "Stigler’s law of eponymy", states that no scientific discovery is named after its original discoverer. Examples include Hubble's law which was derived by Georges Lemaître two years before Edwin Hubble, the Pythagorean theorem although it was known to Babylonian mathematicians before the Pythagoreans, and Halley's comet which was observed by astronomers since at least 240 BC. Stigler himself named the sociologist Robert K. Merton as the discoverer of "Stigler's law" to show that it follows its own decree, though the phenomenon had previously been noted by others.

Jean-Baptiste Biot was a French physicist, astronomer, and mathematician who established the reality of meteorites, made an early balloon flight, and studied the polarization of light. The mineral biotite was named in his honor.

Biot–Savart law Important law of classical magnetism

In physics, specifically electromagnetism, the Biot–Savart law is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The Biot–Savart law is fundamental to magnetostatics, playing a role similar to that of Coulomb's law in electrostatics. When magnetostatics does not apply, the Biot–Savart law should be replaced by Jefimenko's equations. The law is valid in the magnetostatic approximation, and is consistent with both Ampère's circuital law and Gauss's law for magnetism. It is named after Jean-Baptiste Biot and Félix Savart, who discovered this relationship in 1820.

Ernst Chladni German physicist, mathematician and musician

Ernst Florens Friedrich Chladni was a German physicist and musician. His most important work, for which he is sometimes labeled the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases. He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics.

The cent is a logarithmic unit of measure used for musical intervals. Twelve-tone equal temperament divides the octave into 12 semitones of 100 cents each. Typically, cents are used to express small intervals, or to compare the sizes of comparable intervals in different tuning systems, and in fact the interval of one cent is too small to be heard between successive notes.

The millioctave (mO) is a unit of measurement for musical intervals. As is expected from the prefix milli-, a millioctave is defined as 1/1000 of an octave. From this it follows that one millioctave is equal to the ratio 21/1000, the 1000th root of 2, or approximately 1.0006934.

Celsius Scale and unit of measurement for temperature

The Celsius scale, also known as the centigrade scale, is a temperature scale used by the International System of Units (SI). As an SI derived unit, it is used by all countries except the United States, the Bahamas, Belize, the Cayman Islands and Liberia. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale. The degree Celsius (°C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference between two temperatures or an uncertainty. Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps.
