If
Nigerian astronomers can still do research under the conditions
they face, imagine what they could achieve if they had world-class
facilities.
Why
should a country such as Nigeria want to support astronomy? The
government and public are unconvinced that it should. Arguments
based on educational benefits -- using astronomy to attract young
people into science and engineering, understanding our position
in space and time, and so on -- carry little weight. People appreciate
the practical applications of space science, such as remote sensing,
satellite meteorology, and satellite communications, but they believe
that pure science is only of esoteric interest.
The
same public skepticism also frustrates astronomers in developed
countries, but it is not so severe there, since people accept the
need to understand the environment and encourage inquiry. But in
Nigeria most people have no respect at all for science and scientists.
In a country with no welfare system, it is the ability to provide
well for one's family (including the extended family and possibly
one's whole hometown) that is admired. Because an education in pure
science leads to a career as a teacher, which is poorly paid, families
insist that their bright students take up medicine or law. Nigerian
scientists have made efforts to popularize their profession -- for
instance, through a recent radio series -- but the meager job prospects
ensure that those efforts fall on deaf ears.
Despite
this, astronomers at the University of Nigeria in Nsukka, in the
southeast, have managed to undertake research and teaching. The
Department of Physics and Astronomy awards master's degrees and
doctorates in astrophysics, and at present there are four master's
and three doctoral students. Theoretical researchers have concentrated
in high-energy astrophysics, radio astronomy, and cosmology. They
have tried to develop observational projects, but funding has been
a problem.
International
collaboration that makes use of existing instruments seems to be
the best way forward, as this cuts costs and avoids problems with
the security and maintenance of equipment in Nigeria. Nigerian astronomers
have established contacts with South African colleagues at the Hartebeesthoek
and South African Astronomical observatories; they have jointly
observed cataclysmic variables. Now they plan to enable at least
one doctoral student to spend time in South Africa, while providing
materials for other students to continue their work in Nigeria.
At
the undergraduate level, all third-year physics students at the
University of Nigeria have to take introductory astronomy. In the
fourth and final year, they have the option of taking four more
astrophysics courses and completing a project. Elsewhere, astronomy
is slowly spreading. University of Nigeria astronomy graduates are
now lecturers or professors at two universities in the east of the
country, and a university in the west also has introduced astronomy
courses in response to the third United Nations†European Space Agency
workshop on basic space science in Lagos in 1993.
Another
of the problems faced by researchers in Nigeria is poor communications.
Out of 40 universities, two in the west have email facilities, and
even these are unreliable, being dependent on telephone connections
that are themselves intermittent. Recently I tried to send email
to one of those universities. I tried several times over a space
of some weeks, but every time the message bounced back, "host unknown."
At
the University of Nigeria, far from any major city, communications
are especially troublesome. The only certain method is to use courier
services, which are prohibitively expensive. The cost of sending
a manuscript abroad even by ordinary airmail, with a fairly low
probability of actually getting there, is a significant fraction
of researchers' salaries. When anyone travels abroad, he or she
becomes a postman, carrying a hundred or more letters from colleagues
to post. Because of the capricious communications, scientists tend
to publish only in local journals. Not only does this isolate them
from the international community, it means there is little meaningful
feedback on research, since few people read, let alone understand,
the papers.
The
underfunding of universities forces staff to bear all the costs
of communications and publication personally, unless they have managed
to obtain a research grant. For the same reason, computers are scarce.
A few staff members have PCs, either owned privately or in a few
cases obtained through external grants. Most people, however, have
to buy time on PCs if they want to do any computing. Tight security
is needed for any equipment, which further restricts its availability.
Ironically,
the rapid expansion of electronic publishing, which has improved
access for researchers in developed countries, have worsened the
situation for astronomers in other parts of the world. They now
have no hope of keeping up with the latest research and no hope
for the foreseeable future of enjoying the facilities that are taken
for granted elsewhere. Nigerian universities continue to depend
on printed material. Yet the availability of current journals is
very limited; most publications are donations.
This
places a great responsibility on the lecturers as the only source
of information. They need to attend international conferences and
summer schools to stay current, but this, too, depends on international
sponsorship. The Nigerian government supported the 1993 space workshop,
but probably only because the United Nations was involved. And the
Nigerian government is not the only one to wonder why Nigerians
are doing astronomy. One international collaboration was unable
to get off the ground because of visa problems -- the project was
deemed unsuitable for Nigerians.
At
times, I have been told that African scientists are not making enough
effort to convince their governments of the importance of science
education and research. I have also heard African scientists criticized
for getting too involved in university administration and politics
-- to the detriment of their research -- and for being too dependent
on aid programs.
This
is sometimes unfair. It may be necessary to involve oneself in administration
in order to exert pressure for change. Without encouragement from
colleagues elsewhere, the situation can become very depressing.
