Query: Selected Parity Violation Experiments   I start by reviewing existing $\vec{p}p$ measurements with particular
emphasis on the recent 221 MeV $\vec{p}p$ measurement at TRIUMF which permitted
the weak meson-nucleon coupling constants $h^{pp}_\rho$ and $h^{pp}_\omega$ to
be determined separately for the first time. I then review $\vec{n}p$
experiments, with specific details of the $\vec{n}p \to d\gamma$ experiment now
under preparation at Los Alamos National Laboratory. This experiment will
provide a clean measurement of the weak pion nucleon coupling, $f_\pi$.
Finally, I discuss $\vec{e}p$ parity violation experiments, particularly the
Gzero experiment under way at Jefferson Lab in Virginia. This experiment will
measure the weak form factors $G_E^z$ and $G_M^z$, allowing the distribution of
strange quarks in the quark sea to be determined.
