Mikhail Lomonosov
Mikhail Vasilyevich Lomonosov was a Russian polymath, scientist and writer, who made important contributions to literature, education, and science. Among his discoveries were the atmosphere of Venus and the law of conservation of mass in chemical reactions. His spheres of science were natural science, chemistry, physics, mineralogy, history, art, philology, optical devices and others. The founder of modern geology, Lomonosov was also a poet and influenced the formation of the modern Russian literary language.
Early life and family
Lomonosov was born in the village of Mishaninskaya, later renamed Lomonosovo in his honor, in Archangelgorod Governorate, on an island in Northern Dvina not far from Kholmogory, in the far north of Russia. His father, Vasily Dorofeyevich Lomonosov, was a prosperous peasant fisherman turned ship owner, who amassed a small fortune transporting goods from Arkhangelsk to Pustozyorsk, Solovki, Kola, and Lapland. Lomonosov's mother was Vasily's first wife, a deacon's daughter, Elena Ivanovna Sivkova.He remained at Denisovka until he was ten, when his father decided that he was old enough to participate in his business ventures, and Lomonosov began accompanying Vasily on trading missions.
Lomonosov had been taught to read as a boy by his neighbor Ivan Shubny, and he spent every spare moment with his books. He continued his studies with the village deacon, S.N. Sabelnikov, but for many years the only books he had access to were religious texts. When he was fourteen, Lomonosov was given copies of Meletius Smotrytsky's Modern Church Slavonic and Leonty Magnitsky's Arithmetic. Lomonosov was a Russian Orthodox Christian all his life, but had close encounters with Old Believers schism in early youth and later in life he became a deist.
In 1724, his father married for the third and final time. Lomonosov and his stepmother Irina had an acrimonious relationship. Unhappy at home and intent on obtaining a higher education, which Lomonosov could not receive in Mishaninskaya, he was determined to leave the village.
Education
In 1730, determined to "study sciences," the 19-year-old Lomonosov walked all the way to Moscow. Shortly after arrival, he was admitted into the Slavic Greek Latin Academy by falsely claiming to be a son of a Kholmogory nobleman. In 1734 that initial falsehood, as well as another lie that he was the son of a priest, nearly got him expelled from the academy, but the investigation ended without severe consequences.Lomonosov lived on three kopecks a day, eating only black bread and kvass, but he made rapid progress scholastically. It is believed that in 1735, after three years in Moscow he was sent to Kiev to study for short period at the Kiev Academy. He quickly became dissatisfied with the education he was receiving there, and returned to Moscow. In five years Lomonosov completed a twelve-year study course and in 1736, among 12 best graduates, was awarded a scholarship at the St. Petersburg Academy. He plunged into his studies and was rewarded with a four-year grant to study abroad, in Germany, first at the University of Marburg and then in Freiberg.
Education abroad
The University of Marburg was among Europe's most important universities in the mid-18th century due to the presence of the philosopher Christian Wolff, a prominent figure of the German Enlightenment. Lomonosov became one of Wolff's students while at Marburg from November 1736 to July 1739. Both philosophically and as a science administrator, this connection would be the most influential of Lomonosov's life. In 1739–1740 he studied mineralogy, mining, and metallurgy with Bergrat Henckel in his Freiberg laboratory; there, too, he intensified his studies of German literature.Lomonosov quickly mastered the German language, and in addition to philosophy, seriously studied chemistry, discovered the works of 17th century Irish theologian and natural philosopher Robert Boyle, and even began writing poetry. He also developed an interest in German literature. He is said to have especially admired Günther. His "Ode on the Taking of Khotin from the Turks," composed in 1739 - modelled after Günther's poem "Eugen ist fort. Ihr Musen, nach!", 1718, celebrating the taking of Belgrade from the Turks -, attracted a great deal of attention in Saint Petersburg.
Contrary to his adoration for Wolff, Lomonosov had fierce disputes with Henckel over the training and education courses he and his two compatriot students were getting in Freiberg, as well as over very limited financial support which Henckel was instructed to provide to the Russians after numerous debts they had accumulated in Marburg. As the result, Lomonosov left Freiberg without permission and wandered for quite a while over Germany and Holland, unsuccessfully trying to obtain permission from Russian envoys to return to the St. Petersburg Academy.
During his residence in Marburg, Lomonosov boarded with Catharina Zilch, a brewer's widow. He fell in love with Catharina's daughter Elisabeth Christine Zilch. They were married in June 1740. Lomonosov found it extremely difficult to maintain his growing family on the scanty and irregular allowance granted him by the Russian Academy of Sciences. As his circumstances became desperate, he got permission to return to Saint Petersburg.
Return to Russia
Lomonosov returned to Russia in June 1741, after being abroad 4 years and 8 months. A year later he was named an Adjunct of the Russian Academy of Science in the physics department. In May 1743, Lomonosov was accused, arrested, and held under house arrest for eight months, after he supposedly insulted various people associated with the academy. He was released and pardoned in January 1744 after apologising to all involved.Lomonosov was made a full member of the academy and named professor of chemistry in 1745. He established the academy's first chemistry laboratory. Eager to improve Russia's educational system, in 1755, Lomonosov joined his patron Count Ivan Shuvalov in founding Moscow University.
In 1760, he was elected a Foreign Member of the Royal Swedish Academy of Sciences. In 1764, he was elected Foreign Member of the Academy of Sciences of the Institute of Bologna. In 1764, Lomonosov was appointed to the position of the State Councillor which was of Rank V in the Russian Empire's Table of Ranks. He died on 1765 in Saint Petersburg. He is widely and deservingly regarded as the "Father of Russian Science," though many of his scientific accomplishments were relatively unknown outside Russia until long after his death and gained proper appreciation only in late 19th and, especially, 20th centuries.
Science and inventions
Physics
In 1756, Lomonosov tried to replicate Robert Boyle's experiment of 1673. He concluded that the commonly accepted phlogiston theory was false. Anticipating the discoveries of Antoine Lavoisier, he wrote in his diary: "Today I made an experiment in hermetic glass vessels in order to determine whether the mass of metals increases from the action of pure heat. The experiments – of which I append the record in 13 pages – demonstrated that the famous Robert Boyle was deluded, for without access of air from outside the mass of the burnt metal remains the same."That is the Law of Mass Conservation in chemical reaction, which is well-known today as "in a chemical reaction, the mass of reactants is equal to the mass of the products." Lomonosov, together with Lavoisier, is regarded as the one who discovered the law of mass conservation.
He stated that all matter is composed of corpuscles – molecules that are "collections" of elements – atoms. In his dissertation "Elements of Mathematical Chemistry", the scientist gives the following definition: "An element is a part of a body that does not consist of any other smaller and different bodies... corpuscle is a collection of elements forming one small mass." In a later study, he uses the term "atom" instead of "element", and "particula" or "molecule" instead of "corpuscle."
He regarded heat as a form of motion, suggested the wave theory of light, contributed to the formulation of the kinetic theory of gases, and stated the idea of conservation of matter in the following words: "All changes in nature are such that inasmuch is taken from one object insomuch is added to another. So, if the amount of matter decreases in one place, it increases elsewhere. This universal law of nature embraces laws of motion as well, for an object moving others by its own force in fact imparts to another object the force it loses".
Astronomy
Lomonosov was the first to discover and appreciate the atmosphere of Venus during his observation of the transit of Venus of 1761 in a small observatory near his house in St Petersburg. At least in the English-speaking world, this attribution seems to have been owing to comments from the multi-lingual popular astronomy writer Willy Ley, who consulted sources in both Russian and German, and wrote that Lomonosov observed a luminous ring and inferred from it the existence of an atmosphere "maybe greater than that of the Earth". Because many modern transit observers have also seen a threadlike arc produced by refraction of sunlight in the atmosphere of Venus when the planet has progressed off the limb of the Sun, it has generally, if rather uncritically, been assumed that this was the same thing that Lomonosov saw. Indeed, the term "Lomonosov’s arc" has frequently been used in the literature.In 2012, Pasachoff and Sheehan consulted original sources, and questioned the basis for the claim that Lomonosov observed the thin arc produced by the atmosphere of Venus. A reference to the paper was even picked up by the Russian state-controlled media group RIA Novosti on 31 January 2013, under the headline "Astronomical Battle in US Over Lomonosov’s discovery." An attempt was made by a group of researchers to experimentally reconstruct Lomonosov's observation using antique telescopes during the transit of Venus on 5–6 June 2012. One of them, Y. Petrunin, suggested that the telescope Lomonosov actually used was probably a 50 mm Dollond with a magnifying power of 40x.
It was preserved at Pulkovo Observatory but destroyed when the Germans bombed the observatory during World War II. Thus, Lomonosov's actual telescope was not available, but other presumably similar instruments were employed on this occasion, and led the researchers to affirm their belief that Lomonosov's telescope would have been adequate to the task of detecting the arc. Thus A. Koukarine, using a 67 mm Dollond on Mt. Hamilton, where seeing was likely much better than Lomonosov enjoyed at St. Petersburg, clearly observed the spiderweb-thin arc known to be due to refraction in the atmosphere of Venus. However, Koukarine's sketches do not really resemble the diagram published by Lomonosov.
Koukarine's colleague V. Shiltsev, who more nearly observed under the same conditions as Lomonosov, using a 40 mm Dollond at Batavia, Illinois, produced a close duplicate of Lomonosov's diagram. However, the rather large wing of light shown next to the black disk of Venus in his drawing is too coarse to have been the arc. Instead it appears to be a complicated manifestation of the celebrated optical effect known as the "black drop". It should be kept in mind that, as stated in Sheehan and Westfall, "optical distortions at the interface between Venus and the Sun during transits are impressively large, and any inferences from them are fraught with peril".
Again, the actual words used by Lomonosov do not refer to an "arc" at all. In the Russian version, he described a brief brightening lasting a second or so, just before third contact, which appeared to Pasachoff and Sheehan to most probably indicate a last fleeting glimpse of the photosphere. As a check against this, Lomonosov's German version was also consulted; he describes seeing "ein ganz helles Licht, wie ein Haar breit"=”a very bright light, as wide as a hair". Here, the adverb "ganz" in connection with "helles", i.e., as bright as the surface brightness of the solar disk, which is even stronger evidence that this can't be Venus's atmosphere, which always appears much fainter.
Lomonosov's original sketches, if they existed, do not appear to have survived, Modern observations made during the nineteenth century transits and especially those of 2004 and 2012 suggest that what Lomonosov saw was not the arc associated with the atmosphere of Venus at all but the bright flash of the solar photosphere before third contact. The first observers to record the actual arc associated with the atmosphere of Venus, in a form comporting with modern observations, appear to have been Chappe, Rittenhouse, Wayles and Dymond, and several others at the transit in June 1769.
In 1762, Lomonosov presented an improved design of a reflecting telescope to the Russian Academy of Sciences forum. His telescope had its primary mirror adjusted at an angle of four degrees to the telescope's axis. This made the image focus at the side of the telescope tube, where the observer could view the image with an eyepiece without blocking the image. This invention was not published until 1827, so this type of telescope has become associated with a similar design by William Herschel, the Herschelian telescope.
