Clomnya biography

The biography of Johann-Martin-Chladni Clomny came from the family of scientists. Ernest’s great -grandfather - George Homdney - was a Lutheran priest, who in the year, during the Reformation, moved from Sillar to Wittenberg. Grandfather, Martin Khladny was also a Lutheran theologian, and in the year he became a professor of theology at Vittenberg University. Uncle Eustus Khladni - was a professor of law at the same university.

Another uncle, Johann Khladni - was the theologian, historian and professor at the University of Erlangen.

Father Ernst Martin Khladni - was a professor of law and the rector of Wittenberg University and therefore reacted disapprovingly to his son’s interest in science and insisted that Comdnie become a lawyer. Khladni studied jurisprudence and philosophy at the universities of Wittenberg and Leipzig, where he received the degree of Doctor of Law. After the death of his father, Khladni seriously began to engage in research in physics.

Khladni died in the year in Wroclaw at that time this city was called Breslau and was part of the kingdom of Prussia. The plate of the cold one is one of the most famous achievements of the Clocoma is to study different methods of vibration on a mechanical surface. Homni repeated the experiment of the English scientist Robert Huka, who conducted a study at Oxford University in the process during which he noticed changes in the form of the subject when exposed to vibrations on it.

Hook, with a bow along the edge of a plate covered with flour, noticed how the flour was redistributed on the surface, forming clear lines of a complex shape. Khladni recorded his research and published in the year the book “Theory of Sound” “Opening in the theory of sound”. The plate was tilted until it renovated, and the sand formed a certain form. In the XX century, instead of a bow, they began to use a loudspeaker with an electronic signal generator under the plate to reach a more accurate frequency setting.

The methods of this technique are usually used in the design and manufacture of acoustic tools, such as violin, guitar and cello. The figures of the CHALADNI Plate Euphone Cloca - a direct ancestor of a modern musical instrument, known as glass harmonics. Compleni also improved Hook's musical cylinder and invented a clicilinder on its basis in the year. The Law of the Clomnie Law also revealed the scientific activity, the essence of which is that there is a relationship between the frequency of free fluctuations in the plates and other bodies.

Based on the works of Pierre Gassendi on measuring the speed of sound in the air, Khladni conducted an experiment during which he managed to measure the speed of sound in various gases. In the year, Khladni published in German his book “On the origin of the iron masses found by Pallas and other similar phenomena associated with this” [5], in which he investigated Pallaso iron and expressed the cosmic origin of meteorites.

This book became the beginning of the science of meteorics [6].
