Hideki Yukawa
was a Japanese theoretical physicist and the first Japanese Nobel laureate for his prediction of the pi meson, or pion. Biography He was born as Hideki Ogawa in Tokyo and grew up in Kyoto with two older brothers, two older sisters, and two younger brothers. He read the Confucian ''Doctrine of the Mean'', and later Lao-Tzu and Chuang-Tzu. His father, for a time, considered sending him to technical college rather than university since he was "not as outstanding a student as his older brothers". However, when his father broached the idea with his middle school principal, the principal praised his "high potential" in mathematics and offered to adopt Ogawa himself in order to keep him on a scholarly career. At that, his father relented. Ogawa decided against becoming a mathematician when in high school; his teacher marked his exam answer as incorrect when Ogawa proved a theorem but in a different manner than the teacher expected. He decided against a career in experimental physics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Nobel Laureate
Since 1949, there have been 29 Japanese laureates of the Nobel Prize. The Nobel Prize is a Sweden-based international monetary prize. The award was established by the 1895 will and estate of Swedish chemist and inventor Alfred Nobel. It was first awarded in Physics, Chemistry, Physiology or Medicine, Literature, and Peace in 1901. An associated prize, thus far, the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, also sometimes known as the Nobel Prize in Economics, has yet to be awarded to a Japanese national. The Nobel Prizes in the above specific sciences disciplines and the Prize in Economics, which is commonly identified with them, are widely regarded as the most prestigious award one can receive in those fields. Of Japanese winners, twelve have been physicists, eight chemists, three for literature, five for physiology or medicine, and one for efforts towards peace. In the 21st century, in the field of natural science, the number of Japanese winners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morio Yukawa
was a Japanese economist and diplomat. Yukawa served in the Japanese Ministry of Foreign Affairs during World War II and took part in the Japanese official delegation that met US General Douglas MacArthur in Manila on August 19, 1945, in order to make arrangements for the Japanese surrender. During the 1950s, he served as head of Economic Affairs Bureau in the Japanese Ministry of Foreign Affairs, and in that capacity tried to negotiate his country's accession to GATT. He represented Japan at the UNESCO General Session in 1953. Later, he served as Ambassador to the Philippines, and in that capacity concluded the Treaty of Amity of December 9, 1960. Afterwards he served as Head of Mission to the EEC in 1964–1968 and Ambassador to the United Kingdom in 1968-1972. In 1972–1979, Yukawa served as Grand Master of Ceremonies of the Imperial Household Agency The (IHA) is an agency of the government of Japan in charge of state matters concerning the Imperial Family, and also th ...

Tsutomu Yukawa
Tsutomu Yukawa (; 1911–1942) was a Japanese aikidoka. Born in Gobo in Wakayama prefecture, Yukawa began his martial arts training in judo, studying under Tesshin Hoshi. In 1931 he travelled to Tokyo to study at the Kodokan, but whilst in the city he encountered aikido's founder, Morihei Ueshiba, and was soundly defeated. He then took up the study of aikido. While a student at the Kobukan The Aikikai is the original school of Aikido. It is centered on the Aikikai Foundation in Japan, and its figurehead is the Doshu (the family heir of the founder of Aikido). It is represented globally through the International Aikido Federation. ..., Yukawa was known for his physical strength, earning the nickname the "Kobukan Samson". He was strong enough to clap two sacks of rice together and bend iron nails with his hands. Yukawa was one of only a handful of students to study with Ueshiba for more than five years. A favourite student of Ueshiba, he once carried Ueshiba's son Kisshomaru to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukawa Institute For Theoretical Physics
The is a research institute in the field of theoretical physics, attached to Kyoto University in Japan. It was inaugurated in 1952. While the center is often referred to as "YITP", this can be confusing as YITP also stands for the C. N. Yang Institute for Theoretical Physics at Stony Brook University in the United States. Early history In 1949, Japanese theoretical physicist Hideki Yukawa was awarded the Nobel Prize in Physics. He became the first Japanese citizen to receive the Nobel Prize. To commemorate this historic event, the president of Kyoto University immediately proposed to create a memorial hall on campus for Yukawa. In 1950, the Science Council of Japan unanimously resolved a request to the central government to allocate a special funding for the promotion of research in theoretical physics. Enthusiastic discussions among Japanese physicists followed in support for the idea of creating a new institution, similar to the Niels Bohr Institute in Copenhagen or the Institut ...

Yukawa Interaction
In particle physics, Yukawa's interaction or Yukawa coupling, named after Hideki Yukawa, is an interaction between particles according to the Yukawa potential. Specifically, it is a scalar field (or pseudoscalar field) and a Dirac field of the type :~ V \approx g \, \bar\psi \, \phi \, \psi \quad (scalar) \qquad or \qquad g \, \bar\psi \, i \,\gamma^5 \, \phi \, \psi \quad (pseudoscalar). The Yukawa interaction was developed to model the strong force between hadrons. A Yukawa interaction is thus used to describe the nuclear force between nucleons mediated by pions (which are pseudoscalar mesons). A Yukawa interaction is also used in the Standard Model to describe the coupling between the Higgs field and massless quark and lepton fields (i.e., the fundamental fermion particles). Through spontaneous symmetry breaking, these fermions acquire a mass proportional to the vacuum expectation value of the Higgs field. This Higgs-fermion coupling was first described by Steven Weinberg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukawa Potential
In particle, atomic and condensed matter physics, a Yukawa potential (also called a screened Coulomb potential) is a potential named after the Japanese physicist Hideki Yukawa. The potential is of the form: :V_\text(r)= -g^2\frac, where is a magnitude scaling constant, i.e. is the amplitude of potential, is the mass of the particle, is the radial distance to the particle, and is another scaling constant, so that r \approx \tfrac is the approximate range. The potential is monotonically increasing in and it is negative, implying the force is attractive. In the SI system, the unit of the Yukawa potential is (1/meters). The Coulomb potential of electromagnetism is an example of a Yukawa potential with the e^ factor equal to 1, everywhere. This can be interpreted as saying that the photon mass is equal to 0. The photon is the force-carrier between interacting, charged particles. In interactions between a meson field and a fermion field, the constant is equal to the gauge c ...

Yukawa–Tsuno Equation
The Yukawa–Tsuno equation, first developed in 1959,Yukawa Y, Tsuno Y. "Resonance Effect in Hammett Relationship. II. Sigma Constants in Electrophilic Reactions and their Intercorrelation." ''Bull. Chem. Soc. Jpn.'' 32 965-71 (1959) is a linear free-energy relationship in physical organic chemistry. It is a modified version of the Hammett equation that accounts for enhanced resonance effects in electrophilic reactions of para- and meta-substituted organic compounds. This equation does so by introducing a new term to the original Hammett relation that provides a measure of the extent of resonance stabilization for a reactive structure that builds up charge (positive or negative) in its transition state. The Yukawa–Tsuno equation can take the following forms: ::::::::\log \frac = \rho(\sigma + r(\sigma^+ - \sigma)) ::::::::\log \frac = \rho(\sigma + r(\sigma^- - \sigma)) where and represent the rate constants for an X-substituted and unsubstituted compound, respectively; repres ...
