We have counted only the primary physics or physics and astronomy department
in each university. Separate Astronomy departments or auxiliary physics
departments are not included.
Akron and Stevens Tech are
omitted from these tables since they did not present faculty listings in
the directories consulted.
Rms deviations from the mean are given as an estimate of distribution widths.
Counting errors are expected to be much less than the rms deviations.
Six ranked departments gave up their PhD program between 1992 and 1999.
Thirty four departments not ranked in the 1992 NRC survey are now listed
as having PhD programs. These more than compensate for the slight loss of
faculty indicated for the programs in the tables here.
The average ratio of subatomic physics to superatomic physics is dominated among
the top schools by Rockefeller University in the 1990 data although we have
arbitrarily decreased their subatomic faculty by one and increased their
superatomic faculty by one to regularize the average.
Perhaps a quick overview of the trends of the last decade can be had
by plotting the ratio of subatomic physicists to
superatomic physicists in the top N physics departments as a function of N.
The new PhD programs in the 1999 AIP directory that were not present in the
1995 NRC rankings were alphabetically assigned a rank below the currently
ranked departments. For the most part these are relatively small programs
which do not significantly affect the integrated faculty numbers.
Again one should be cautioned that the 1999 faculty ratios are compared with
the 1995 rankings. Changes in the rankings could be expected to
occur in response to changes in departmental research profiles.
It is also interesting to compare the
top ten states in public support of
physics with the subatomic ratio in their publicly supported PhD programs.
