Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. Any of a class of particles, such as the photon, pion, or alpha particle, that have zero or integral spin and obey statistical rules permitting any number of identical particles to occupy the same quantum state.

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. A particle with totally symmetric composite quantum states, which exempts them from the Pauli exclusion principle, and that obey Bose-Einstein statistics. They have integer spin. Among them are many elementary particles, and some (gauge bosons) are known to carry the fundamental forces. Compare fermion.
  • n. A boatswain.

from the GNU version of the Collaborative International Dictionary of English

  • n. A fundamental particle that obeys Bose-Einstein statistical rules, but not the Pauli exclusion principle; the spin value of a boson is always an integer. Examples of bosons are alpha particles, photons, and those nuclei which have an even mass number.
  • n. See boatswain.

from The Century Dictionary and Cyclopedia

  • n. A corruption of boatswain, representing its common pronunciation.
  • n. A bolt for the crossbow, having a round knob at the end, with a small point projecting from it.

  • Seems very Vonnegutian.

  • As do I. It seems right somehow.

  • Strangely, I find it comforting that the beginning of the universe can be undone by a bird with a chunk of bread.

  • "The $6.5 billion machine designed to recreate the conditions present at the beginning of time had to be switched off after a bird dropped a 'bit of baguette' into it, causing it to overheat. As a result, scientists at the Large Hadron Collider in Switzerland had to postpone their plans last week to emulate the universe's Big Bang.
    The European particle physics laboratory near Geneva launched the LHC in September last year. Physicists hoped to prove the existence of the Higgs boson, or God particle, which gives matter in the universe its mass."
