Today the concept of the nucleus of an atom as a cluster of protons and neutrons orbited by electrons is sufficiently familiar that is easy to forget that in at least one sense something one might not expect is going on. Within the tremendously dense nucleus, charged proton is pressed against charged protonin other words, positive charge hard against another positive. Extraordinarily powerful forces must be holding them against each other. In fact, this is called the Strong Forceit is the strongest of the 4 fundamental forces of nature which we understand to exist. (The other 3 are the Weak Force, Electromagnetic Force and Gravity.) By the early 1930s, Japanese physicist Hideki Yukawa concerned himself with the Strong Force, that force that holds together the nucleus. Not until 1947, with a marvelous new film from the Ilford Company exposed at a high altitude, was the meson's existence actually captured. The name "yukon" seems to have been seriously considered, but was thought to have been spoken for by the Canadian territory of the same name (though Yukons at many scales might have made a nice pattern for Powers of Ten Interactive). Yukawa won the Nobel Prize in 1949. His mesons are now known as pions (or pi-mesons) and there are many other kinds of meson as well.

The positive and negative pions have longer lifetimes of about 2.6 x 10 s. The negative pion decays into a muon and a muon antineutrino as illustrated below. This decay is puzzling upon first examination because the decay into an electron plus an electron antineutrino yields much more energy. Usually the pathway with the greatest energy yield is the preferred pathway. This suggests that some symmetry is acting to inhibit the electron decay pathway. The symmetry which suppresses the electron pathway is that of angular momentum, as described by Griffiths. Since the negative pion has spin zero, the electron and antineutrino must be emitted with opposite spins to preserve net zero spin. But the antineutrino is always

In a most innocent manner they simply adore it. It was only a day before that Masatoshi Koshiba won the Nobel Physics Prize. Then on Wednesday, the Nobel jury announced that Koichi Tanaka, another Japanese, was chosen to be awarded the Prize in Chemistry. This is the third straight year that the Prize was won by Japanese. Ryoji Noyori, a Nagoya University professor, won the Nobel chemistry prize last year, and Hideki Shirakawa, a professor emeritus at Tsukuba University, won the same Prize in 2000. This in fact makes for this year's Tanaka the third winner in a row for the Chemistry Prize. Koshiba and Tanaka would mark the 11th and 12th Japanese Nobel laureate to date. Koshiba is the fourth Japanese to win the Physics Prize, and Tanaka is also the fourth to win the chemistry prize.

Back to the main menu Origin The history of the Yukawa Institute for Theoretical Physics (former Research Institute for Fundamental Physics) goes back to 1949 when Hideki Yukawa of Kyoto University (then staying at Columbia University) was awarded the first Nobel Prize for a Japanese citizen. 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 physicists from all over the country followed in support for the idea of creating a new institution, similar to the Niels Bohr Institute in Copenhagen or the Institute for Advanced Study in Princeton. Yukawa Hall was inaugurated in 1952 and in the following year (1953) it became the Research Institute for Fundamental Physics (RIFP). Yukawa was appointed as the first director of the institute and led the institute until his retirement in 1970.

La preleganto estis S-ro Nigel Evans, konsulo de EU en Japanio (diplomito de universitato Birmingham, Britio), kiu priskribis ghiajn konkretajn pashojn. Kaj tuj post lia parolado, mi demandis pri du punktoj. Al mia unua demando pri "kopirajto" kiun pretendas pluraj landoj, li respondis, ke li antauvidas efektivighon de unuigho en la kadro de EU, char ghi celas politikan aliancon de dudek kelkaj landoj, inter ili ankau 6 orienteuropaj landoj, kaj progresigas reguligon de komplikitaj interesoj. Mia dua demando estis pri lingva problemo de EU. Mi demandis: "Nun, kiam realighis la komuna mono Euro, kiu estis konsiderata de multaj antaue kiel nura revo, la plej granda problemo estas, lau mia audo, lingva muro. 34 procentoj de la ghenerala kaso por mastrumado estas elspezata por tradukado kaj interpretado, kaj lau mia kompreno ghenerala tajdo estas unuigho per angla lingvo. Tamen ekzistas forta obstaklo, mi audas, char tio por chiam avantaghas nur angla-lingvanojn, kiuj kovras nur 18 procentojn de la tuta loghantaro. Aliflanke, oni elektis kiel himnon de EU t.n. *Ghojo*, au simfonio n-ro 9 de Beethoven, kaj rilate al tio S-ino Philia Thalgott, Konsiliano de EU, petas al la Parlamento, ke ghia teksto estu en Esperanto.
