In Russia, Ivan Akimovich (1726 - 91)
Place of the Saxon noble family. He studied and graduated from the course at the University of GцІttingen. In mid-1757 came in the number of teachers at Moscow University in the rank of associate. Invitation to take this position received from academicians and well-known Russian historian Miller, . which then was in constant correspondence, . contains some interesting information on the status and activities of the Moscow University in the early decades of its existence,
. Subject of teaching P. in the first year of operations at the Moscow University was the English language. Proceed to teaching mathematics, as his special subject, he was able only from next year, when the ruling took place on a university conference on the instruction of teaching him and Master Barsov. R. taught in Latin, not all of his listeners to understand this language, and he had to choose one of the students his translator, who, during the lecture was translated into Russian and explain everything the professor said. When caused by the new contract with the University Teaching recess R. during 1761, he became a full professor and the division of teaching with the new professor Anichkov assumed applied mathematics and experimental physics. This division is, however, was not strictly. There were years when the subjects of their normal teaching P. are added and some of the divisions of pure mathematics. Applied mathematics P. read on composing Veydlera: "Institutiones Matheseos selectis observationibus illustratae in usum academicarum", made up of separate parts, covering both pure and applied mathematics. The latter was represented by the following departments: Optica proprie dicta, . Ars perspectiva, . Catoptrica, . Dioptrica, . Astronomia sphaerica, . Astronomia theorica, . Geographia generalis, . Chronologia, . Gnomonica, . Mechanica, . Hydrostatica, . Aerometria, . Hydraulica, . Architectura civilis, . Architectura militaris,
. All of these sciences in the teaching of R., with the exception of astronomy, took more than one year, but several, with no definite order in their pursuit of each other was not observed. They were often prisoedinyaemy professor is not contained in the book Veydlera surveying, underground geometry, artillery, the theory of friction and hydro. For the teaching of mathematics, distinguished general at elementariness, P. usually appointed 4 two-hour lectures a week, and for the teaching of experimental physics - such as two lectures. Experimental physics R. expounded in the first years of teaching on composing Winkler: "Anfangsgrunde d. Physik "(Leipzig, 1753), and then on the books" Philisiphia naturalis, experimentisconfirmata "(3 books, Halle, 1753) by Johann Gottlieb Krueger and" Course of Experimental Philosophy "by J. F. Desaguliers (London, 1717 and 1745). For the production of physical experiments during lectures P. had laboratory: first Frenchman Peter Dyumulenya, and then the Italian Joseph Maggi. Lectures of Experimental Physics P. had a very big success, they met students from all faculties. In addition to lectures for students, P. read more, with the help of student translators, public lectures on physics, cosmology, sometimes with the accession to outsiders, and gave many private lessons. R. possessed remarkable linguistic information, was considerably higher than his knowledge of mathematics and physics. He knew theoretically and practically languages: Latin, Greek, French, German, English, Dutch, Italian and Spanish. Not leaving the University, P. held since 1763 for several years, chief warden at the newly founded then the educational building. Despite its vastness, teaching was for P. only secondary importance. The main subject of his studies were commercial enterprises, . consisted in the purchase of various parts of Russia and in sending abroad the ships from the Dutch-Russia company, . agent and the commission of which he was, . various raw materials: corn, . hemp, . fat, . hair, . down and pr,
. If you can not leave Moscow, he led all of these big commercial affairs with the help of a few hundred stewards, which he kept on the payroll in various parts of Russia. Trading activity P. made him a very wealthy man. He was in Moscow own house and left after the death of his two sons more than 1000 souls of the peasants and the capital of several hundred thousand rubles. The same is strictly practical nature and trained for different literary works of R., which consisted entirely of speeches he delivered in solemn assemblies of the University and then published in Latin and Russian languages. The development and solution of issues taught them science P. not involved. Therefore, the subject of his speeches were not the achievements of these sciences, and various practical issues, for some reason is particularly important or interesting to contemporaries. Thus, the need for improvement of Russian cities, closing at their limits cemeteries served as a theme in his first speech: "De effluviorum in corporibus, inprimis animalium, penetranti efficacia", delivered on April 22, 1765. Another of his speeches were: "De faciliori melioris fontium salis praeparatione" (1769), . "De aere nocuo in triclintis praesertim plebeiorum et quomodo ille facili negotio salubrior reddi potest" (1772), . "De commodis in Russia contra incendiorum furorem adminiculis" (1774), . "De perenni gloria Imperantium, . quam ex felicitate populi promota acquirunt "(1776), . "De eo, . quod conducit et observari oportet ratione valetudinis in eligendo exstruendarum urbium novarum loco "(1781) and" Oratio solemnis, . qua Dominae Catharinae II de itinere feliciter peracto per Rossiam meridionalem ea, . qua decet, . gratulatur Joannes Joachimus Julius Rost D,
. XXX Junii "(1787). Biography R., compiled by Professor Cereal, published in the biographical dictionary of professors and teachers of the Imperial Moscow University "(Part II, page. 362 - 369). VV. Bobynin.
