  Recent empirical work in the field of 'weak measurements' has yielded novel
ways of more directly accessing and exploring the quantum wavefunction.
Measuring either position or momentum for a photon in a 'weak' manner yields a
wide range of possible values for the measurement, and can be done in such a
way as to only minimally effect the wavefunction rather than to collapse it to
a specific precise value. Measuring the other complementary variable (position
or momentum) precisely at a later time ('post-selection') and averaging the
weak measurements can yield information about the wavefunction that is not
directly experimentally obtainable using other methods. This paper discusses
two recent papers on weak measurement in the context of the uncertainty
principle more broadly, and considers some possibilities for further research.
