	ATCS Article - Pioneers of Sound - Ernst Chladni
		Hooke observed that the motion of the glass was to vibrate perpendicular to the surface of the glass, thus producing circular patterns in the flour.
		Chladni was one of the first in the scientific community to state publicly that meteorites feel from the sky.
		Chladni wrote a number of treatises on the theory of sound and acoustics.

	Ernst Chladni
		Ernst Florenz Friedrich Chladni (1756-1827) was a German physicist born in Wittenburg.
		With his work on vibrating plates and the calculation of the speed of sound for different gases, Chladni was the founder of acoustics.
		The patterns formed by a thin layer of sand on a vibrating plate are called "Chladni patterns".

	Chladni plate interference surfaces
		Chladni plate interference surfaces are defined as positions where N harmonics cancel.
		The basic experiment that is given the name "Chladni" consists of a plate or drum of some shape, possibly constrained at the edges or at a point in the center, and forced to vibrate historically with a violin bow or more recently with a speaker.
		Ernst Chladni first demonstrated this at the French Academy of Science in 1808, it caused such interest that the Emperor offered a kilogram of gold to the first person who could explain the patterns.

		He developed an experimental technique whereby sand is vibrated on a metal plate and settles into regular and symmetric patterns (Chladni's figures), indicating the nodes of the vibration's wave pattern.
		Chladni was born in Wittenberg, Saxony, and studied law at Leipzig.
		He also measured the velocity of sound in various gases by measuring the change in pitch of an organ pipe filled with a gas other than air (the pitch, or sound frequency, varies depending on the molecular composition of the gas).

		One of Chladni's most well known achievements was inventing a technique to show the various modes of vibration in a mechanical surface.
		Chladni's technique, first published in 1787 his book, Entdeckungen ueber die Theorie des Klanges, consists of drawing a bow over a piece of metal whose surface is lightly covered with sand.
		He invented a musical instrument called Chladni's euphonium, consisting of glass rods of different pitches, which should not be confused with a brass euphonium.

	ERNST CHLADNI
		Chladni observed that when a metal plate covered with sand or other similar substance was made to vibrate by running a violin bow across it perpendicularly, a pattern emerged in the sand.
		He produced diagrams of his experiments which came to be called, "Chladni figures." He went on the lecture circuit in Europe and demonstrated his finding to live audiences, which included a command performance for Napoleon.
		Chladni invented a musical instrument called the 'Euphonium' made of glass rods and steel bars that were sounded by being rubbed with the moistened finger, and traveled about Europe performing on this instrument and giving scientific lectures.

		The diagrams of Ernst Chladni (1756-1827) are the scientific, artistic, and even the sociological birthplace of the modern field of wave physics and quantum chaos.
		(Chladni was also the first to maintain that meteorites were extraterrestrial; before that, the popular theory was that they were of volcanic origin.) One of his diagrams is the basis for image, which is a playfully colored version of Chaldni's original line drawing.
		Chladni's original work on waves confined to a region was followed by equally remarkable progress a few years later.

	Ernst Chladni and Rocks from the Sky
		Ernst Florens Friedrich Chladni (1756–1827) was fascinated by science and music from a young age, but was trained as a lawyer at the insistence of his father, a professor of law in Wittenberg, Germany.
		Chladni’s interest in meteorites was stimulated in 1793 by a conversation with Georg Lichtenberg, professor of physics at the University of Göttingen.
		Chladni found numerous cases in which fireballs were followed by the fall of rock or iron masses to the ground.

		It was Napoleon who said of the German physicist, Ernst E.F. Chladni (1756-1827) that "Chladni has made sound visible." Using clamped plates of various materials with fine sand on their top surfaces, Chladni demonstrated vibration patterns ("Chladni figures") formed in the sand by drawing a bow down the plate"s edge.
		Chladni, professor of physics in Breslau, was the first to reduce the general association between vibration and pitch to a tabular basis and thus to lay the foundation of the modern science of acoustics.
		Chladni schließt: "Si j"ai ete le premier qui a concu et execute l"idee de produire des vibrations transversales par le frottement longitudinal d"une verge de verre, M. Savart est le premier qui l"a bien appliquee a des recherches tres interessantes sur la nature des vibrations [...]";.

		In the confined context of the acoustic figures described initially by Robert Hooke in 1665 and in more detail by Ernst Chladni in 1787 (often referred to as Chladni figures), a novel visual phenomenon was observed.
		Chladni investigated the vibrations of flat plates, and the patterns produced by certain sounds.
		He scattered fine sand evenly over a horizontal glass or metal plate, clamped at one end, and set it in vibration with a violin bow; symmetrical patterns were formed where the sand gathered.

	Nanowerk Spotlight
		In 1787, the German physicist Ernst Chladni showed how sand particles could be made to self-organize into symmetrical patterns.
		Chladni also reported how fine particles (fine shavings from the hairs of his violin bow) would move in the opposite direction, to the antinodes.
		The demonstration of Chladni figures in microfluidics opens the door to highly parallel, directed assembly and to size-based sorting or size-dependent manipulation of particles, organelles, or cells.

	Cymatics History
		Musician and physicist Ernst Chladni laid the foundation for the discipline in physics that came to be called "acoustics" — the science of sound.
		Using an organ pipe filled with gas, he was able to show that the pitch of sound is dependent upon the molecular structure of the gas through which it propagates.
		In 1850, his doctoral thesis was based on vibrating bars using Chladni's sand patterns and nodal theories.

	Summary of Background Information
		Chladni is called ‘the father of acoustics’ for his study into how sound affects physical matter.
		The application of this research to the present paper is found mainly in the Chladni patterns and their ability to recreate themselves on the front and back plates of a stringed instrument.
		At first, it was tempting to compare the Chladni pattern photos I found on the internet to the data from the experiment, but then I realized that the internet photos were taken of violins, a totally different animal in terms of resonance frequencies than the cello.

	The Structure and Dynamics of Waves and Vibrations by Hans Jenny
		Among Chladni´s successes was finding a way to make visible what sound waves generate.
		Chladni demonstrated once and for all that sound actually does affect physical matter and that it has the quality of creating geometric patterns.
		In this book Jenny, like Chladni two hundred years earlier, showed what happens when one takes various materials like sand, spores, iron filings, water, and viscous substances, and places them on vibrating metal plates and membranes.

	The Power of Vibration
		One of the first people in our time to render vibration into visible forms was the eighteenth-century German physicist Ernst Chladni, who began by scattering sand on steel disks and observing the changing patterns produced by playing various notes on a violin.
		These “Chladni figures” which have so inspired artists and symbolists, result from the fact that the disk resonates to the violin only in certain places, shifting the sand to those areas which are inert.
		Chladni’s work inspired the late Hans Jenny of Zurich to spend ten years duplicating and expanding his experiments with sophisticated equipment, and he named the pursuit cymatics, the study of the interrelationship of waveforms with matter.

		The symmetry of the Chladni figures is partially determined by the symmetry of the plates chosen.
		What we see on the Chladni type plates is none other than the same phenomena described by wavenumber earlier.
		In addition, the Chladni plates are nothing but another manifestation of Plateau's surfaces of revolution.
