Ivan Mikhailovich Sechenov (Russian: Иван Михайлович Сеченов) was a Russian natural scientist, psychologist and physiologist, teacher and educator.
Ivan Mikhailovich was born into an impoverished noble family in the village of Teply Stan, Kurmysh uyezd, Simbirsk province (now the village of Sechenovo, Nizhny Novgorod region), graduated from the Main Military Engineering School, then from the Medical Faculty of Moscow University. For three and a half years Sechenov studied in Germany, engaged not only in biological disciplines, but also in physics and analytical chemistry. Abroad he became friends with S. P. Botkin, D. I. Mendeleev, A. P. Borodin, and the artist A. Ivanov.
In 1860 in St. Petersburg at the Imperial Academy of Medicine and Surgery Sechenov defended his dissertation on "Materials for the Physiology of Alcoholic Intoxication" and received the degree of Doctor of Medicine. Soon he received the post of extraordinary professor at this academy and organized one of the first physiological laboratories in Russia in his department. His record includes work in the laboratory of D. I. Mendeleev, head of the Department of Physiology at Odessa Novorossiysk University, teaching at St. Petersburg University, and professor in the Department of Physiology at Moscow University. Sechenov gave much effort to the development of women's education. He participated in the organization and work of the Higher Women's Courses in the capital, taught at women's courses at the Society of Educators and Teachers in Moscow.
Ivan Sechenov is the founder of the doctrine of mental regulation of behavior, the creator of the first physiological scientific school in Russia. For the first time in history he substantiated the reflex nature of conscious and unconscious activity. He showed that the basis of mental phenomena is physiological processes, substantiated the importance of metabolic processes in the realization of the body's reactions to stimuli. He laid the foundations of physiology of labor, age, comparative and evolutionary physiology. He studied the respiratory function of blood.
Sechenov's main works: "Reflexes of the brain" (1863), "Physiology of the nervous system" (1866), "Elements of thought" (1878), "Sketch of human working movements" (1901), etc. In addition, Sechenov edited "The physiology of the nervous system" (1866). In addition, Sechenov edited translations of books by foreign scientists. Thus, in 1871-1872 under his editorship in Russia was published a translation of Charles Darwin's work "The Origin of Man and Sexual Selection". Among his students were Ilya Mechnikov, Ivan Pavlov, Kliment Timiryazev, Nikolai Vvedensky, and Ivan Tarkhanov, who became famous scientists.
Robert Hill Jackson or Bob Jackson is a Pulitzer Prize-winning American photographer.
Robert attended Southern Methodist University while pursuing a passion for photography. While serving in the National Guard, Jackson became a photographer for an Army general. In 1960, he began working as a photo reporter for the Dallas Times Herald newspaper.
On November 22, 1963, Jackson was assigned to cover President John F. Kennedy's arrival at Love Field and his motorcade through the city. He witnessed Kennedy's assassination, but did not have time to film it. Two days later, however, he was able to photograph the shooting of Lee Harvey Oswald, the accused assassin of President Lee Harvey Oswald, by Jack Ruby in the garage of the Dallas police station. Robert Jackson was awarded the 1964 Pulitzer Prize in Photography for these photographs.
Galileo Galilei was an Italian naturalist, physicist, mechanic, astronomer, philosopher, and mathematician.
Using his own improved telescopes, Galileo Galilei observed the movements of the Moon, Earth's satellites, and the stars, making several breakthrough discoveries in astronomy. He was the first to see craters on the Moon, discovered sunspots and the rings of Saturn, and traced the phases of Venus. Galileo was a consistent and convinced supporter of the teachings of Copernicus and the heliocentric system of the world, for which he was subjected to the trial of the Inquisition.
Galileo is considered the founder of experimental and theoretical physics. He is also one of the founders of the principle of relativity in classical mechanics. Overall, the scientist had such a significant impact on the science of his time that he cannot be overemphasized.
Joan Miró, a celebrated Spanish artist, was a master in painting, sculpture, and ceramics, renowned for his unique style that blurred the lines between Surrealism, Fauvism, and Expressionism. Born in Barcelona to a family of a goldsmith and a watchmaker, Miró grew up immersed in the rich cultural heritage of the Barri Gòtic neighborhood. His artistic journey began with drawing classes at the age of seven and continued at the prestigious La Llotja art academy. Despite an initial venture into the business world, Miró's passion for art prevailed, leading him to abandon his clerical career after a nervous breakdown.
Miró's work is noted for its exploration of the subconscious, often depicting a childlike perspective. This approach was both a critique of traditional painting methods and a means of expressing Catalan pride. His art, challenging to categorize, often featured symbolic elements and nationalistic qualities. One of his notable early works, "The Farm," reflects a transition to a more individual style, blending elements of his Catalan roots with broader artistic influences. This piece, later purchased by Ernest Hemingway, encapsulated the essence of Spain in its imagery.
In Paris, Miró joined the Surrealist movement in 1924, where his work began to reflect the influence of automatism, emphasizing spontaneous, automatic, or subconscious creation. He experimented with various mediums, including painting-poetry and collage, and even ventured into set and costume design for Sergei Diaghilev's Ballets Russes.
During World War II, Miró remained in Spain, and his work from this period, including the 22 Constellations series, reflected an interest in the night, music, and stars. His forms became increasingly abstracted, and he experimented with various techniques, often incorporating primary colors and evocative titles.
Miró's career spanned several decades, during which he continually evolved his style and explored new mediums. His contributions to art were recognized with numerous awards and retrospectives, including a major career retrospective at MoMA in 1941 and the Spanish Gold Medal for Fine Arts in 1980. Among his last major works was a tapestry for the World Trade Center in New York City, created in 1974.
For art collectors and enthusiasts, Joan Miró remains a figure of immense interest, not only for his distinct style and contributions to Surrealism but also for his ability to blend poetic imagery with political commentary.

Isaac Newton was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus.
In the Principia, Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System's heliocentricity. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. Newton's inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Maupertuis, La Condamine, and others, convincing most European scientists of the superiority of Newtonian mechanics over earlier systems.
