  The American Physical Society (APS) March Meeting of condensed matter physics
has grown to nearly 10,000 participants, comprises 23 individual APS groups,
and even warrants its own hashtag (#apsmarch). Here we analyze the text and
data from March Meeting abstracts of the past nine years and discuss trends in
condensed matter physics over this time period. We find that in comparison to
atomic, molecular, and optical physics, condensed matter changes rapidly, and
that condensed matter appears to be moving increasingly toward subject matter
that is traditionally in materials science and engineering.
