SCIENTIFIC EDUCATIONAL CENTER science idea

Mikhail Vasilyevich Lomonosov (November 19, 1711 – April 15, 1765) 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. Founder of modern geology, Lomonosov was also a poet and influenced the formation of the modern Russian literary language.

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 was 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" (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." In a later study (1748), he uses 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).

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.

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. 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.

In 1763, he published On The Strata of the Earth – his most significant geological work. 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.

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).

In 1755 Lomonosov wrote a grammar that reformed the Russian literary language by combining Old Church Slavonic with the vernacular tongue. To further his literary theories, he wrote more than 20 solemn ceremonial odes, notably the Evening Meditation on God's Grandeur. 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.
