Mikhail Lomonosov

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 and philosophy at the University of Göttingen; there he intensified his studies of German literature.^[15]

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, attracted a great deal of attention in Saint Petersburg.^[15]

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.^{[citation needed]}

During his residence in Marburg, Lomonosov boarded with Catharina Zilch, a brewer's widow.^[16] He fell in love with Catharina's daughter Elizabeth Christine Zilch. They were married in June 1740.^[17] 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.^[15]

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.^[15] 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.^[15]

Lomonosov was made a full member of the academy and named professor of chemistry in 1745.^[15] He established the academy's first chemistry laboratory.^[18] Eager to improve Russia's educational system, in 1755, Lomonosov joined his patron Count Ivan Shuvalov in founding Moscow University.^[18]

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.^[19] 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 4 April (o.s.), 1765 in Saint Petersburg. He is widely and deservingly regarded as the "Father of Russian Science,"^[20] 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.

Physics

In 1756, Lomonosov tried to replicate Robert Boyle's experiment of 1673.^[21] 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.^[22]

He stated that all matter is composed of corpuscles – molecules that are "collections" of elements – atoms. In his dissertation "Elements of Mathematical Chemistry" (1741, unfinished), 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."^[23] In a later study (1748), he uses the term "atom" instead of "element", and "particula" (particle) 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" (first articulated in a letter to Leonhard Euler dated 5 July 1748, rephrased and published in Lomonosov's dissertation "Reflexion on the solidity and fluidity of bodies," 1760).^[24]

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.^[15][25] 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 (1966), who consulted sources in both Russian and German, and wrote that Lomonosov observed a luminous ring (this was Ley's interpretation and was not indicated in quotes) and inferred from it the existence of an atmosphere "maybe greater than that of the Earth" (which was in quotes). 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.^[26]

In 2012, Pasachoff and Sheehan^[27] 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.^[28]

It was preserved at Pulkova 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.^[29] 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.^[30][31]

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 (and Lomonosov's) 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 (he had learned to speak and write German fluently as a student at Marburg) 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" (bright) could mean "as bright as possible" or "completely bright"), 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.^[32]

Chemistry and geology

In 1759, with his collaborator, academician Joseph Adam Braun, Lomonosov was the first person to record the freezing of mercury and to carry out initial experiments with it.^[33] Believing that nature is subject to regular and continuous evolution, he demonstrated the organic origin of soil, peat, coal, petroleum and amber. In 1745, he published a catalogue of over 3,000 minerals, and in 1760, he explained the formation of icebergs.^[15]

In 1763, he published On The Strata of the Earth – his most significant geological work.^[34] This work puts him before James Hutton, who has been traditionally regarded as the founder of modern geology. Lomonosov based his conceptions on the unity of the Earth's processes in time, and necessity to explain the planet's past from present.^[3][2]

Geography

Lomonosov's observation of iceberg formation led into his pioneering work in geography. Lomonosov got close to the theory of continental drift,^[35] theoretically predicted the existence of Antarctica (he argued that icebergs of the Southern Ocean could be formed only on a dry land covered with ice),^[36] and invented sea tools which made writing and calculating directions and distances easier. In 1764, he organized an expedition (led by Admiral Vasili Chichagov) to find the Northeast Passage between the Atlantic and Pacific oceans by sailing along the northern coast of Siberia.^[15]

Engineering

The idea of a coaxial rotor originated from Mikhail Lomonosov. In July 1754, he developed a model of a small helicopter with a coaxial rotor and demonstrated it to the Russian Academy of Sciences.

Mosaic

Lomonosov was proud to restore the ancient art of mosaics. In 1754, in his letter to Leonhard Euler, he wrote that his three years of experiments on the effects of chemistry of minerals on their colour led to his deep involvement in the mosaic art. In 1763, he set up a glass factory that produced the first stained glass mosaics outside of Italy. There were forty mosaics attributed to Lomonosov, with only twenty-four surviving to the present day. Among the best is the portrait of Peter the Great and the Battle of Poltava, measuring 4.8 by 6.4 metres (16 ft × 21 ft).^[37][38][39]

Grammarian, poet, historian

Besides his scientific activities, Lomonosov also paid considerable attention to literature.^[40] Together with his contemporaries Alexander Sumarokov and Vasily Trediakovsky, Lomonosov sought the creation of a system of Russian linguistic conventions, syntax and prosody which would allow the advancement of a native literary tradition on the basis of Western European genres.^[41] He laid out his literary theories in his work "Epistle on the Rules of Russian Versification" (1739). Lomonosov is considered the founder of accentual-syllabic (or syllabo-tonic) verse in Russian poetry,^[40] although statistical analysis suggests the adoption of this system was already in progress when Lomonosov publicized his theories.^[41] His "Ode on the Taking of Khotin" has been called the first "aesthetically indisputable example" of accentual-syllabic verse in the history of Russian literature. The iambic tetrameter and hexameter verse and the ten-line odic stanza which he developed had a lasting role in Russian poetry. His advocacy of the iamb won out over Trediakovsky's arguments for the trochee as the basic metrical foot.^[41]

Lomonosov wrote solemn occasional, spiritual, as natural-philosophical odes, as well as an Anacreontic ode.^[40] According to A. Kahn, "the turgidity of the Lomonosovian ode derives from a propensity to create semantic clusters, usually through etymologic play or tropes, such as zeugma." His "Evening Meditation on God's Grandeur" and "Morning Meditation on God's Grandeur" are the first Russian poems on the theme of sublime admiration of nature.^[41] He applied an idiosyncratic theory to his later poems – tender subjects needed words containing the front vowel sounds E, I, Y and U, whereas things that may cause fear (like "anger", "envy", "pain" and "sorrow") needed words with back vowel sounds O, U and Y. That was a version of what is now called sound symbolism.^{[citation needed]} He also wrote two verse tragedies, Tamira i Selim and Demofont.^[40]

Lomonosov wrote an important Russian grammar in 1755 (published in 1757), in which he distinguished Old Church Slavonic and colloquial Russian forms. His work on rhetoric "Kratkoye rukovodstvo k krasnorechiyu" (Brief guide to eloquence, 1748) is the first such work in Russian and expounds a theory of literature on the basis of Russian literary models. His treatise "Predisloviye o polze knig tserkovnykh v rossiyskom yazyke" (Introduction to the usefulness of church books in the Russian language, 1757) is the first Russian work on stylistics. Lomonosov adopted classical views on the existence of three distinct styles—high, middle, and low—and applied them to the Russian literary language. It also addresses the problems of the combination of Church Slavonic and Russian forms and the categorization of literary genres.^[40] In 1760, Lomonosov published a history of Russia.^[42][43] In addition, he attempted to write a grand Aeneid-inspired epic about Peter the Great, but he died before he could finish it.^[44]
