A brief biography of Hideki Yukawa
A brief biography of Hideki Yukawa - Hideki Yukawa was born on January 23, 1907, in Tokyo, Japan. He was the third child of Takuji Ogawa, a Professor of geology at the University of Kyoto. He obtained his m. S from the University of Kyoto in 1929 and D.Sc. (equivalent to S3 in Indonesia) from Osaka University in 1938.
Yukawa became a lecturer at the University of Kyoto since 1932 to 1938. In 19 * 39, he was appointed Professor of theoretical physics at the University. He also served as an Assistant Professor at Osaka University.
Hideki Yukawa likes world of physics deals with the elementary particles since young. His interest in the world of theoretical physics much influenced by his professors, k. Tamaki in Kyoto and n. Nishina in Tokyo.
At the time of Hideki Yukawa, a 27 year old Yukawa produced works entitled "On the Interaction of elemtary Particles I". It lays out a new theory of the nuclear force and predicted the existence of particles called Mesons.
According to Yukawa, the electromagnetic force is carried by photons is equal to nuclear power brought by meson. When the right one type of meson discovered American physicist Yukawa in 1937, the more passionate to concentrate his research on the development of the theory of the meson.
Originally, the Yukawa particle imparts a plan that is found with the name "Yukon," as a form of respect for him. However, the scientists first called it "meson," because the particles are among the masses of the electron and the proton mass, ranging from 200-300 times the mass of the electron.
The discovery of the particle pi-meson in 1947 made a name Yukawa is increasingly popular. Among the scientists are increasingly convinced that the Yukawa theory of nuclear force is on the right track. The discovery of the meson made Yukawa was confirmed as a Nobel Laureate in physics. The money received is then donated to set up the new Institute of Theoretical Physics in Kyoto, Japan.
The discovery of the meson theory does not make Yukawa complacency. He continued to develop his theories by examining the research world elementary particles. The method called not local field theory has helped many developments of the theory of nuclear physics.
Methods that are derived from these many ideas are published in scientific journals and his book "Introduction to Quantum Mechanics" and "Introduction to the Theory of Elementary Particles."
Aside from doing research in the theory of elementary particle, Yukawa still took the editor of the journal of the Progress of Theoretical Physics.
American physicist, Oppenheimer invite Yukawa to Princeton to join the nuclear physics group. He became a professor at Columbia University, the United States in 1949. In his inaugural address as Professor in the Columbia University Oppenheimer said the prediction Dr. top Yukawa meson is one of a very brilliant idea in the last decade.
Hideki Yukawa in daily is very loved by all his colleagues, both as a physician and as a person.
In busy researchers, Yukawa still takes themselves to be active in social activities. In July 1981, he along with a group of scientists made a statement prohibiting the use of nuclear weapons.
Yukawa is a figure nuclear scientists against nuclear use for purposes not good. Hideki Yukawa died in November 1981
Hideki Yukawan inventor of the Meson Theory
Hideki Yukawa gets Nobel Prize thanks to his invention of the nuclear force and the electromagnetic force. He applied quantum field theory, in which the electrons and protons are bound to each other through the photon. Attachment of nucleons is also caused by the phenomenon of quantum field exchange core style of the high interaction.
The idea of this style was first coined by Yukawa in 1935 to describe the force binding protons and neutrons in the deuteron. He proposed a strong force, mediated by particles that do not comply with the prohibition of exclusion eventually known as a pawn.
Today's modern theory explains that the high force is working on the most elementary particles, i.e. quark. Quark-quark was tied with powerful particle by mediators called gluons (from the word glue).
However, experiments show that quarks are never free from the prison that is called particle physicists as confinement.
Quark can only exist both (form Mesons) or trees forming the nucleons (protons and neutrons). The last discovery showed the possibility of a quark could also exist five exotic particles form a pentaquark.
Helplessness quark to live alone outside the proton has produced the most severe problem in particle physics at the time. Experiments showed, if two quarks inside the protons try to style the second belt, dropped Quark is getting bigger.
Even if it is forced using adding kinetic energy on both the quark, the law of conservation of energy finally hands down. Quark also arranges two new particles was formed.
