So, out of all the erudite Vorts, no one can answer the
following simple questions:
Why are the UP-spin quarks on OPPOSITE sides of the proton
from the DOWN-spin quarks???
Short answer: erudition eroded... alternatively: not simple.
Long answer. A proton is composed of two up quarks and one down quark, so
they logically cannot be arranged as opposites. A handy visualization is
"Borromean rings" and a more technical version is the Efimov state.
Why, in some nuclear interactions, do two gammas go shooting
off in OPPOSITE directions???
That one appears to be conservation of momentum, but the connection to quark
spin, if there is one, is not clear.
Wiki sez: In classical mechanics, linear momentum or translational momentum
is the product of the mass and velocity of an object.... Linear momentum is
a conserved quantity and the gamma has equivalent mass, even if the rest
mass is zero.
Why is the magnetic field PERPENDICULAR to the E-field???
This is also related to momentum in a way (if one is trying to find a
connection) - since the EM wave moves forward by transferring energy back
and forth between the two fields, and that momentum is conserved. As one
field collapses the other field builds, so the waves must be at right angles
to each other, since at any other angle there would be inequality in the
transfer.
