  • The numbers indicate volume flux in Sverdrups (106 m3/s) rounded to half-integer values and are based on observations, with the exception of the surface outflow, which is adjusted to balance [1].

  • You will sometimes hear physicists explain that elementary particles come in two types: bosons, which have a spin of 0, 1, 2, or some other integer, and fermions, which have a spin of 1/2, 3/2, 5/2, or some other half-integer.


  • This year they pick the spin-statistics theorem, which explains why elementary particles with half-integer […] 22.


  • The fact that these sets of features come hand-in-hand is the content of the spin-statistics theorem: particles that pile on have integer spins, particles that take up space have half-integer spins.


  • If the universe obeys a symmetry called “supersymmetry” which relates bosons (integer spin particles) to fermions (half-integer spin particles) then there must exist a supersymmetric partner for every particle we know about.

  • The spin-statistics theorem states that fermions have half-integer spin.

    Walter Kohn and Density-Functional Theory

  • Particles that have integer spin are called bosons, while those with half-integer spin are called fermions.

  • This principle was later found to be associated with the symmetry of wave functions for particles of half-integer spins in general, distinguishing what is now called fermions from the bosonic particles whose spins are integer multiples of.

  • Math tells us that all the fermions-particles with half-integer spin-must come from what is known as the

  • Spin has a direction and variable magnitude, but has to be a half-integer: 0, 1/2, 1, 3/2, and so on.
