  1. proton(noun)

    a stable particle with positive charge equal to the negative charge of an electron


  1. proton(Noun)

    A positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element; the nucleus of the most common isotope of hydrogen; composed of two up quarks and a down antiquark

  2. Origin: From πρῶτον, neuter of πρῶτος


  1. Proton

    The proton is a subatomic particle with the symbol p or p+ and a positive electric charge of 1 elementary charge. One or more protons are present in the nucleus of each atom. The number of protons in each atom is its atomic number. The name proton was given to the hydrogen nucleus by Ernest Rutherford in 1920, because in previous years he had discovered that the hydrogen nucleus could be extracted from the nuclei of nitrogen by collision, and was thus a candidate to be a fundamental particle and building block of nitrogen, and all other heavier atomic nuclei. In the modern Standard Model of particle physics, the proton is a hadron, composed of quarks. Prior to that model becoming a consensus in the physics community, the proton was considered a fundamental particle. In the modern view, a proton is composed of three valence quarks: two up quarks and one down quark. The rest masses of the quarks are thought to contribute only about 1% of the proton's mass. The remainder of the proton mass is due to the kinetic energy of the quarks and to the energy of the gluon fields that bind the quarks together. Because the proton is not a fundamental particle, it possesses a physical size—although this is not perfectly well-defined since the surface of a proton is somewhat fuzzy, due to being defined by the influence of forces that do not come to an abrupt end. The proton is about 1.6–1.7 fm in diameter.

    I've been thinking about that old Zen conundrum what's the sound of one hand clapping My personal opinion--nothing. You don't have two hands, you don't have any clapping. It's as simple as that. Stars, galaxies, clapping hands, what's the point The point is that we all need somebody, whether you're a supercluster or a little proton, a yin or a yang. Everybody is hooked into everybody else.

  2. Andrew Schneider:

    Marriage is the union of disparate elements. Male and female. Yin and yang. Proton and electron. What are we talking about here Nothing less than the very tension that binds the universe. You see, when we look at marriage, people, we're are looking at creation itself. I am the sky, says the Hindu bridegroom to the bride. You are the earth. We are sky and earth united.... You are my husband. You are my wife. My feet shall run because of you. My feet shall dance because of you. My heart shall beat because of you. My eyes see because of you.
