Extractions: Savart's Wheel Hampden-Sydney College Colby College Washington and Jefferson College Felix Savart (1791-1841) is probably best known for his 1820 investigation (with Biot) of the strength of a magnetic field as a function of the local geometry and the current through a wire. Most of his research dealt with acoustics, including Savart's wheel, which he used for research on the lower frequency limit of hearing. . Demonstrations with Savart's wheel ought to convince anyone of the source of sound. The wheel is set spinning, and a playing card or a file card is held against the serrations on the rim of the wheel. At very slow rotation rates, the eye can see the edge of the card moving, but at higher rates it blurs, and a tone is produced. The frequency is directly proportional to the rotation rate. If some sort of counter were provided, Savart's wheel can be used, along with a stopwatch, to find the frequency of the sound. Thus, like the siren , it can be used for the absolute determination of pitch.

Extractions: Savart's Cup and Resonator Felix Savart (1791-1841) is probably best known for his 1820 investigation (with Biot) of the strength of a magnetic field as a function of the geometry of a wire and the current through it. But, most of his research dealt with acoustics, including the first explanation of the operation of a violin. The edge of the cup or bell of Savart's apparatus is set into oscillation with a violin bow to produce a sound of definite pitch. The sliding piston of the resonator is then moved in and out to give the maximum amplitude of sound. Note that the relatively large diameter of the resonator gives large end corrections; the wavelength of the resonant wavelength is larger than four times the interior depth. The Union apparatus is by the Paris firm of Lerebours et Secretan, and is listed at 400 francs in the 1853 catalogue. Amherst College Colby College
The Sound The logarithmic unit is the savart (felix savart, French physicist). That isto say to find the interval in savart between 660 and 440 = f1 / f2 = 1,5. http://uk.geocities.com/piklemas/Soneng.html
Extractions: The sound The audible sounds are vibrations whose frequency lies between 20Hz and 20000Hz, these limits varying with the individuals. Among the audible sounds one distinguishes the musical sounds resulting from one or more vibrations of determined frequency and persisting long enough, and the noises due to nonperiodic vibrations, or of which the period and the amplitude evolve quickly. So that periodic vibrations correspond to a perceptible sound it is necessary that they have a sufficient amplitude and that their frequencies lie between certain limits. Under 20Hz, the vibrations form the field of infrasons; with the top of 20000Hz that of the ultrasounds. The study of the sounds can be objectively made way independence of the properties of the ear. The musical sounds are characterized by three physiological qualities: intensity, the height and the stamp. A musical instrument can play strong or gently: we will say that in the first case, the emitted sounds are more intense than in the second. It is easy to note that the sound is all the more intense since the source, for a given frequency, vibrates with a greater amplitude: the violin emits an intense sound when the bow strongly attacks the cord; the piano emits an intense note when the key is inserted energetically. The ear will be all the more strongly affected that the sound will bring a greater vibratory energy to him: this energy grows like the square of the amplitude.

Extractions: Feature: April 2000 Colin Gough received the 2001 Science Writing Award for Professionals in Acoustics from the Acoustical Society of America for this article. Stradivarius violins are among the most sought-after musical instruments in the world. But is there a secret that makes a Stradivarius sound so good, and can modern violins match the wonderful tonal quality of this great Italian instrument? Is there really a lost secret that sets Stradivarius violins apart from the best instruments made today? After more than a hundred years of vigorous debate, this question remains highly contentious, provoking strongly held but divergent views among players, violin makers and scientists alike. All of the greatest violinists of modern times certainly believe it to be true, and invariably perform on violins by Stradivari or Guarneri in preference to modern instruments. The violin is the most highly developed and most sophisticated of all stringed instruments. It emerged in Northern Italy in about 1550, in a form that has remained essentially unchanged ever since. The famous Cremonese violin-making families of Amati, Stradivari and Guarneri formed a continuous line of succession that flourished from about 1600 to 1750, with skills being handed down from father to son and from master to apprentice. The popular belief is that their unsurpassed skills, together with the magical Stradivarius secret, were lost by the start of the 19th century.
CMH - Work With Saunders reasons, but Saunders wrote back on February 14, 1950, saying that it seemed likea lot of work and reviewing the problems that felix savart (17911841)a http://www.catgutacoustical.org/people/cmh/laird3.html
Extractions: Work With Saunders In 1949, the same year that Hutchins began her study as a luthier, Helen Rice introduced her to Frederick A. Saunders (1875-1963), a retired Harvard physicist who had been conducting research on violin acoustics since the early 1930s. Best known for the Russell-Saunders coupling (a principle of atomic spectroscopy), Saunders had been chair of the physics department at Harvard, a fellow of the National Academy of Sciences, and one-time president of the Acoustical Society of America. An amateur violinist and violist, he tried her viola and said that he would look forward to seeing her next one. At that point, Hutchins insists, she had no intention of making another. After speaking with Saunders and reading some of his articles, Hutchins realized how she could help him: [FN 14] ...the only thing he'd ever been able to do was to work with musicians who came with the instruments as they were. He didn't dare change anything except to maybe take a little bit of wax and put a penny, or a little bit of weight on the bridge... What Hutchins offered was to build instruments on which Saunders could make actual changes, like the position and size of the f-holes or height of the ribs. Evidence of this joint work is found in the many surviving letters from Saunders to Hutchins.
The Biot-Savart Law Shortly after Oersted's discovery in 1819 that a compass needle is deflected by acurrentcarrying conductor, Jean Baptist Biot and felix savart reported that http://content.engineering.com/engineering/templates/article/0,1016,BC936B498834
Extractions: From their experimental results, Biot and Savart arrived in an expression that gives the magnetic field at some point in space in terms of the current that produces the field. The Biot-Savart law says that if a wire carries a steady current I, the magnetic field d B at a point P associated with an element of the wire ds has the following properties:
Physics 253 May 29, 1996 Not long after Oerstead's discovery that a current carrying wire sets up a magneticfield, Jean Baptiste Biot and felix savart made this business quantitative. http://zebu.uoregon.edu/~kevan/ph253/052996/052996.html
Extractions: In the last lecture, we deduced the magnetic force on a particle of charge q traveling at velocity v parallel to an electric current I: To be consistent with the Lorentz force equation (with E = 0) we need to define the magnitude of B to be Note that this result is specific to a linear current that extends infinitely in both directions. The general validity of the Lorentz force equation rests upon experimental verification - we can always find a B that makes it valid. All we have done is to figure out a relationship between B and current. While B decreases radially as 1/r, the field itself is not radial. The field must be perpendicular to both the force, which is directed radially inward for q and v greater than 0, and to the velocity. A little thought will convince you that the field is tangential to a circle of radius r: In the above figure, the field is properly labeled if we are looking in the direction that the particle is traveling, and this is also the direction of the current. That is, the field 'circulates' in a clockwise direction, when viewed along the direction of the (positive) current. If we changed the direction of the current, then the field would change the sense of its circulation.

Extractions: Science and the Stradivarius Is there really a lost secret that sets Stradivarius violins apart from the best instruments made today? After more than a hundred years of vigorous debate, this question remains highly contentious, provoking strongly held but divergent views among players, violin makers and scientists alike. All of the greatest violinists of modern times certainly believe it to be true, and invariably perform on violins by Stradivari or Guarneri in preference to modern instruments. Violins by the great Italian makers are, of course, beautiful works of art in their own right, and are coveted by collectors as well as players. Particularly outstanding violins have reputedly changed hands for over a million pounds. In contrast, fine modern instruments typically cost about £10 000, while factory-made violins for beginners can be bought for under £100. Do such prices really reflect such large differences in quality?
