Pyotr Leonidovich Kapitsa or Peter Kapitza ( Russian: Пётр Леонидович Капица, Romanian: Petre Capița (8 July [ O.S. [5][6] Besides Russian, the Kapitsa family also spoke Romanian.[7]. Kapitsa was born in Kronstadt, Russian Empire, to Bessarabian-Volhynian-born parents Leonid Petrovich Kapitsa (Romanian Leonid Petrovici Capiţa), a military engineer who constructed fortifications, and Olga Ieronimovna Kapitsa from a noble Polish Stebnicki family. His wife and two children died in the flu epidemic of 1918–19. In 1939 he developed a new method for liquefaction of air with a low-pressure cycle using a special high-efficiency expansion turbine. Since then, researchers have employed vibrations to make liquids levitate in midair and to get air bubbles to sink somewhat than increase. Because of the weight of the liquid, the air underneath the levitating layer is denser, and that denser air is pushing the boat up into the liquid, counteracting the downward force of gravity. But with the slightest disturbance, that equilibrium is lost, and the pendulum swings downward. Pyotr Kapitsa - WikiMili, The Free Encyclopedia - Wik 26 June] 1894 – 8 April 1984) was a leading Soviet physicist and Nobel laureate, best known for his work in low-temperature physics. [12], In 1978, Kapitsa won the Nobel Prize in Physics "for his basic inventions and discoveries in the area of low-temperature physics" and was also cited for his long term role as a leader in the development of this area. The Kapitsa–Dirac effect is a quantum mechanical effect consisting of the diffraction of electrons by a standing wave of light. And I’m still amazed by the results.”. That does not work with a layer of water, which easily ripples and becomes unstable. Dr. Fort’s levitating liquid research started when he heard a talk about Kapitza’s pendulum, named after Pyotr Kapitsa, a Russian physicist who in 1951 described how, if the pendulum were vibrated up and down at the correct frequency, it would remain in the upright configuration indefinitely. At the same time pyotr Kapitsa was also working on the viscosity of the superfluid below lambda point.This period was the period of second world war and Stalin was working on nuclear weapons.so he forced kapitza to stay in Moscow and do the research work there only. Petr Leonidovich Kapitsa - Soviet physicist, engineer and innovator. Kapitsa was married in 1927 to Anna Alekseevna Krylova (1903-1996), daughter of applied mathematician A.N. Pyotr Leonidovich Kapitsa The Soviet physicist Pyotr Leonidovich Kapitsa (1894-1984) made notable contributions to knowledge of atomic structures and to understanding the behavior of matter in strong magnetic fields and at extremely low temperatures. The higher viscosity suppresses ripples. “Indeed when you see these boats, it’s a bit like fantasy,” Dr. Fort said. Those all floated upside down on the bottom side of the levitating liquid. Even if you first pour a layer of oil into a container and then carefully add water on top, the heavier water will start dripping through the oil, forming tentacles that reach the bottom. The Russian physicist Pyotr Leonidovich Kapitsa (1894-1984) made notable contributions to knowledge of atomic structures and to understanding the behavior of matter in strong magnetic fields and at extremely low temperatures. 2, 2020 , 11:00 AM If you’re a water sports fan looking for a new thrill, what about upside-down sailing? That’s why oil floats on water. In principle, they could have done much more. From 1957, he was also a member of the presidium of the Soviet Academy of Sciences and at his death in 1984 was the only presidium member who was not also a member of the Communist Party. Kapitsa's studies were interrupted by the First World War, in which he served as an ambulance driver for two years on the Polish front. Pyotr Leonidovich Kapitsa or Peter Kapitza (Russian: Пётр Леонидович Капица, Romanian: Petre Capița (8 July [O.S. The scientists initially used small round beads for their research, but they then started using their 3-D printer for other shapes of plastic to float upside down. “That was also a very nice part outside of the narrow scope of science.”, Up Is Down in This Fun Physics Experiment. [11] While dining at his old college, Trinity, he found he did not have the required gown. “There’s no limit; you just have to shake more,” Dr. Fort said. [10], In 1966, Kapitsa was allowed to visit Cambridge to receive the Rutherford Medal and Prize. He reported the properties of this new state of matter in a series of papers, for which he was later awarded the Nobel Prize in Physics "for basic inventions and discoveries in the area of low-temperature physics". Pyotr Leonidovich Kapitsa or Peter Kapitza (Russian: Пётр Леони́дович Капи́ца, Romanian: Petre Capiţa (8 July [O.S. The vibrations, about 100 cycles a second, caused bubbles injected into the liquid to be pushed downward, forming an air cushion below the levitating liquid. The idea might not be so outlandish. People who came to the laboratory and saw the experiment generally had two reactions, Dr. Fort said. He was the first director (1930–34) of the Mond Laboratory in Cambridge. 26 June] 1894 – 8 April 1984) was a leading Soviet physicist and Nobel laureate, best known for his work in low-temperature physics. [8] He graduated from the Petrograd Polytechnical Institute in 1918. In a new study, physicists have managed to float tiny boats on the underside of a layer of liquid levitating […] He asked to borrow one, but a college servant asked him when he last dined at high table, "Thirty-two years" replied Kapitza. 26 June18941 – 8 April 1984) was a leading Soviet physicist and Nobel laureate,23 best known for his work in low-temperature physics.
