Enrollments
Our undergraduate enrollments are up from last
year, not just the introductory courses AST101
141 registered students AST105 262
registered (Mars closeness caught
attention??) AST248 230 registered (Life in
universe preferred to life on LI?) PHY113 NEW
Physics of Sport closed out at 50 PHY121 351
registered PHY122 133 registered PHY131
302 registered PHY132 91 registered
PHY125 87 registered But also our junior
level majors courses PHY301 44 registered
(these are unprecedented) PHY303 42 registered
Are Physics and Astronomy gaining in
popularity? Is there a demographic change in the
university? We should view these upturns as an
opportunity! We continue to need to improve in
finding opportunities for research projects for
undergraduates, and the increased number of
majors amplifies this need.

Budgets
The university
budget outlook continues to be poor for the
coming year. The New York State economic climate
remains bad. It will be a difficult year to
advance new initiatives.

News of the faculty
David Fossan died on July 27, 2003. Dave joined
the Stony Brook faculty in 1965 after a postdoc
at the Niels Bohr Institute and a research
position with Hewlett Packard. He was a founding
member of the Nuclear Structure Laboratory, and
his research into nuclei in extreme conditions of
deformation and angular momenta were
internationally recognized. Dave won the
Chancellors award for Excellence in Research in
2002.
8
Emeritus Professor Nandor Balazs died on Aug. 16,
2003. He joined the Stony Brook faculty in 1961,
and his breadth of knowledge and eclectic style
helped shape the department over four decades.
His personal associations with Einstein,
Schrödinger, Dirac, Chandrasekhar and Wigner gave
Stony Brook a link to these giants of 20th
century physics. Nandor officially retired in
1995 but remained an active participant in the
department and in physics internationally.
9
Luis Orozco has resigned from our faculty as of
August 2003 to take up a position at the
University of Maryland where he will help lead
the establishment of a new atomic physics group.
Luis continues as an adjunct professor at Stony
Brook and will continue some research activities
here.
Norbert Pietralla will join the faculty
officially in January 2004. Norbert is a leading
expert in nuclear structure studies who has made
ground-breaking studies of symmetries and
collective states in heavy nuclei. Pietralla
holds the prestigious Emmy Noether junior faculty
fellowship at Cologne University, and has held a
research appointment at Yale.

Simons Lecturers
The bequest by the Simons Foundation will be used
this year to sponsor two special lecturers who
will visit the department for a week or more and
give a combination of colloquium and seminar
level talks. The lecturers will also be
available for discussions and interactions with
students and faculty. Lecturers were chosen to
present recent advances of physics and astronomy,
and to represent theoretical fields not strongly
represented at Stony Brook. David Spergel of
Princeton University will bring news of the
recent WMAP satellite measurements (and other
experiments) of cosmological parameters. He will
visit for the week of March 15-19. (Host Michal
Simon) Henk Stoof of the University of Utrecht
will discuss theoretical aspects of Bose Einstein
condensation. His visit will span several weeks
starting in mid-April. (Host Hal Metcalf)

PHYSICS AND MATH BUILDING MASONRY REPAIR
STATUS Current Project Status Masonry probes
were performed in March 2003 to determine the
condition of the masonry facade, corner soldier
brick courses, masonry column enclosures, and
relieving angle structures by all the windows.
Scope of Work for the masonry repairs are
defined. Budgetary Cost estimates for masonry
repair and new roof were completed 1.86M A
project start date has not been scheduled because
the NYS Legislature has not allocated a Capital
Budget for any state universities or
colleges. The good news is that when the Capital
Budget is finally allocated by the State
Legislature, The Physics and Math Building is at
the top of the list. A Scope of Work and cost
estimate has been completed, and the project is
ready for engineering design.
22
The building
WATER LEAKS (Big problems over the
summer) Most of the perimeter of the roof
mechanical room has been sealed against water
penetrations due to rain. The Mechanical room
rain scuppers and downspouts have been repaired
to eliminate water leaks from the roof. However,
the cooling coil condensate trays for AC-1 and
AC-2 cannot be relined and waterproofed until the
cooling season is over, and the air handlers can
be shut down and condensate trays drained. In
addition, two mechanical room floor drain
plumbing lines will be repaired during the
shutdown.

50M KOPIO experiment to measure CP violation in
KL ? p0 n n at Brookhaven was approved by NSF and
Congress with Mike Marx as Project Manager. The
KOPIO summer interns made a game to recognize the
nifty events in real time. (http//www.phy.bnl.gov
/millerc/KOPhome.html)
  Within the last few milli-seconds, Earth has
been threatened by a group of evil Alien
physicists and only you (yes, I'm speaking to
you) can stop their evil plot of world
domination. As a sign of their fairness, they
offer us a "best of out of seven competition," to
decide our fate. If we win, the Aliens will halt
their assault on Earth and offer us the highly
coveted secret of making 20 minute brownies in 15
minutes. However, if we lose, they plan to do
something really, really, really evil and bad
like...so evil that it would make evil people
seem less eviler.
          The Aliens have already defeated us in
Chinese Checkers, arm wrestling (Props to the
ripped Zriged), and leap frog. However, we
earthlings have destroyed them in tic-tac-toe,
ultimate-frisbee, and badminton. Now, it comes
down to the tie-breaker and you have been chosen.
The category that you have selected is Quantum
Nonlinear Higher-Dimensional Theoretical
Mathematics.           After five grueling
hours, the final score is 10,832 to -3, and it's
not in your favor. In other words, you LOST!!!!
Good going, Einstein. The earth has been doomed
because of your failure. Then, a minute later,
you begin to cry (you big baby). The Aliens look
upon thee, and decide to give you a second
chance, while laughing at your pitiful self. They
decide on this game....if you feel bold,
press the "Enter" button to save the
world.

The SMARTs telescopes at Cerro Tololo Stony
Brook, Yale, American Museum of Natural History,
Ohio State, Johns Hopkins and Georgia State
formed a consortium to operate three 1 meter
class telescopes. Stony Brook has rights for
about 100 nights of observations. Stony Brook
effort led by Fred Walter and Mike Simon.

This data was analyzed by V. Lore (USB 2003) as
part of an AST487 senior research project and A.
Nencke, an REU visiting student in summer 2003.

Deane Peterson has used optical interferometry to
deduce the oblateness of hot, rapidly spinning
stars, near the breakup angular velocity. Data
are consistent with gravitationally induced
surface brightnesses and further measurements
will test the 1924 theory. These are the first
measurements of the orientation of rotation axes
of an individual star other than the sun.
35
Aaron Evans, Phil Solomon have studied ultra
luminous infrared galaxies ULIGs which are
high red shift objects with the IR luminosity
comparable to that of quasars.
Evans et al. data
False color IR images with molecular gas contours

ULIGs are massive galaxies in the making with
O(102) ordinary star formation rates. They are
probably Quasars in formation, with gas feeding
the supermassive black holes. The recently
launched Space Infrared Telescope Facility will
examine these objects in much more detail.
36
Visiting Professor Paul Hickson has recently
operated the LZT 6 m liquid mercury telescope
near Vancouver and obtained FWHM image resolution
of 3 arc sec. Improvements to the mirror can
bring this down to the target 1 1.5 arc sec.
LZT is a prototype for the LAMA array, led by Ken
Lanzetta of 18 such liquid mirrors of 8-10 m
diameter, whose equivalent light gathering is
that of a 40 m diameter single mirror! LAMA is
presently in its Phase 0, leading to a Conceptual
Design Report for external review at the
beginning of 2004.

MANIPULATING ATOMS WITH THE BICHROMATIC FORCE
Why the bichromatic force (2 lasers at different
n) ???
Its HUGE, and it spans a HUGE velocity range!!!
VELOCITY SPACE MAP
Hal Metcalf
The left shows the result of the ordinary optical
force used for laser cooling for the past 20
years. It moves atoms from one small region of
velocity space to another close by. The plot is a
line-out of intensity.
The right side shows that the bichromatic force
collects atoms from a MUCH larger region of
velocity space (dark area) and also moves them by
a MUCH larger amount (brightness), indicating a
MUCH larger force.
The arrow shows the force direction, and thus the
velocity change. The plots are on the same scale.
