  Core-polarization (CP) and Brown-Rho (BR) scaling were among Gerry's most
favorite topics. In this contribution, we will discuss some of the early
history as well as more recent work associated with these two fascinating
phenomena. I (TTSK) will begin with some recollections of Princeton, where I
met Gerry for the first time in 1964 and worked as his postdoc. Core
polarization was in fact the first topic he assigned to me. JWH started working
with Gerry at Stony Brook from 2003 and was Gerry's last student in nuclear
physics. We three had teamed up well, working closely on both CP and BR
scaling, particularly on the latter's connection to the anomalously-long
beta-decay lifetime of carbon-14. We shall here briefly review these topics,
including a recently developed new Brown-Rho scaling based on a Skyrmion
half-Skyrmion two-phase model.
