First observation of a cell nucleus

The Scottish botanist Robert Brown made an observation of a cell nucleus in 1831, he noted the central body in the cells of the orchids of genuses Orchidaceae and Asclepiadaceae. He even called this structure the “nucleus” of the cell. Continue reading

Prediction of the existence of Mesons

Japanese physicist Yukawa Hideki was awarded the Nobel Prize in Physics in 1949. For his prediction of the existence of mesons that was made in 1935, during his lecturer at Osaka Imperial University in Osaka, Japan. He postulated a particle that mediated the strong interaction between nucleons (the particles of the atomic nucleus).

This particle, the “pi meson” or “pion”, was finally discovered in 1947.

Several other types of mesons of varying mass have been found; the first being observed in cosmic ray interactions in 1937 by American scientists.

Date:
      1935
Name(s):
      Yukawa Hideki
Occupation:

  • Meson – Wikipedia
    In particle physics, mesons (/ˈmiːzɒnz/ or /ˈmɛzɒnz/) are hadronic subatomic particles composed of one quark and one antiquark, bound together by the strong interaction.
  • List of mesons – Wikipedia
    Mesons are unstable subatomic particles composed of one quark and one antiquark. They are part of the hadron particle family – particles made of quarks.
  • What’s the reason behind the existence of mesons? | Physics Forums …
    I’ve read that mesons consist of a quark and an antiquark. So, here’s my question. Why don’t the quark and the anti-quark annihilate with each other (like they ususally do)?
  • meson | subatomic particle | Britannica.com
    Meson, any member of a family of subatomic particles composed of a quark and an antiquark. Mesons are sensitive to the strong force, the fundamental interaction that binds the components of the nucleus by governing the behaviour of their constituent quarks.
  • Hadrons, baryons, mesons – HyperPhysics Concepts
    Mesons are intermediate mass particles which are made up of a quark-antiquark pair.
