Israeli
astronomers have come a long way on limited resources, but at least
they don't have to spend much effort battling pseudoscience: public
education is strong, and religion and science coexist peacefully.
Astronomy
gained its foothold in modern Israel with the popularization efforts
of Asher Ehrlich in British-controlled Palestine, but did not emerge
as an academic discipline until the early 1970s. Today, five of
the seven Israeli universities have astronomy programs. The Israeli
astronomical community sees itself as a modern scientific establishment
in the European or American model, but with some special problems
shared with the less developed world.
Israeli
astrophysicists concentrate on cosmology, gravitation, and compact
objects; Tel Aviv University has observational programs into active
and starburst galaxies, novae and cataclysmic variables, faint stellar
companions, and solar-system research. In all, there are about 40
senior faculty and a similar number of graduate students. The annual
budget for astronomy is about $2 million, mostly for faculty salaries.
Support for students and expensive research comes from research
agencies and private foundations, including the German-Israel Foundation
and Israel-U.S. Binational Science Foundation.
The
only professional observatory in Israel is the Wise Observatory
in Mitzpe Ramon. Located in the northern Negev desert at an altitude
of 900 meters (3000 feet), Mitzpe Ramon has about 240 usable and
170 excellent nights a year, with average seeing of 2 arcseconds.
Although the 1-meter telescope is small by today's standards, for
many programs -- monitoring variable stars and galaxies, wide-field
searches, and collaborations such as the Whole Earth Telescope --
it has advantages: a large field of view, excellent instrumentation,
large blocks of time, and a location 12 hours from Hawaii in a region
with few large telescopes. For larger telescopes and non-optical
wavelengths, Israeli astronomers apply for time at telescopes in
Europe and the Americas. Still, the astronomical community agrees
that it needs a larger telescope, perhaps through a joint-venture
with Egypt in the Sinai.
One
of the reasons for building a new telescope would be to attract
back the Israeli astronomers who work overseas. Like other small
countries of limited means, Israel loses good young scientists to
wealthier countries: the ``brain drain.'' Faculty encourage recent
Ph.D.s to go abroad so that the research community will not get
ingrown, but many never return. In 1990-1991, Israel was on the
receiving end of a brain drain: Thousands of technically educated
people immigrated from the former Soviet Union. They experienced
culture shock in adapting to Israeli science -- they had never heard
of grant applications, for example -- but most, after some adjustment,
found scientific or engineering jobs.

In
other aspects, Israeli science outperforms that of many richer countries.
Elementary and high schools teach mathematics and physics thoroughly;
a high-school graduate has typically done as much as an American
college freshman. Astronomy is usually taught outside of the formal
physics curriculum, in special projects directed by dedicated astronomers.
Young students enjoy the Skylab traveling planetarium and programs
at the Perchai Meda ("Science Seedlings") center. High-school
students can team up with university faculty on research projects,
which are graded by the Ministry of Science and count towards extra
credit in the baccalaureate exams. Keen public interest benefits
astronomy greatly. The largest newspaper, Maa'riv, runs a
full-page article on astronomical research every week (although
they also carry an astrology column). Large audiences attend public
lectures at the Tel Aviv Planetarium, and astronomers often appear
at social clubs, veteran's organizations, and synagogues. Israel
has an active Astronomical Society of mixed amateur and professional
membership.
The
interaction of science, religion, pseudoscience, and anti-science
in Israel or any other society is complex, but there are clear differences
from the United States. Religion plays a more dominant role in public
and private life than it does in America, but usually coexists smoothly
with modern science. Many rabbis, for instance, refuse to bless
sick people until they agree to conventional treatment. Orthodox
Jews are well represented in science, medicine, and engineering.
Astrology is taken less seriously than in the United States, probably
because traditional Judaism frowns on it. There are, however, certain
days and months thought to be lucky or unlucky. When the collision
of Comet Shoemaker-Levy with Jupiter started on the 9th of Av, the
most unfortunate day in the Jewish calendar, people called the observatory
wondering whether this "meant something." The struggle
between biologists and creationists is largely avoided, because
those who object strongly to the scientific picture are likely to
live in isolated communities and run their own schools.
Israeli
astronomers have always been active in international collaborations,
partly because most have worked in other countries and have close
ties with them, partly because astronomical projects are so demanding
that no one country can support them. Israeli and Russian scientists
are working together on the largest collaboration yet: the Tel Aviv
University Ultra-Violet Explorer (TAUVEX), an ultraviolet imager
on the Spectrum Roentgen Gamma satellite, due for launch
from Kazahkstan in early 1996. Israelis and Russians visit freely
back and forth, a sign that some things do change for the better
in this world.

a lecturer in the Department of Astronomy at Tel Aviv University
in Ramat Aviv, Israel. She discovered the joys of infrared spectroscopy
while a graduate student in Berkeley, Calif., and though she has
worked at wavelengths from the ultraviolet to the radio, she still
believes the most interesting astrophysics lives in the infrared.
