In Ghana, the number of women involved in physics has been rather small compared with that of men. We report a gratifying increase in the number of women studying physics in Ghana during the past 5 years. This is the positive result of various intervention strategies that have been put in place in Ghana during the past 15 years. It is estimated that the developing countries of Africa need at least 2000 scientists per 1 million in population for effective industrial development. If this critical mass of scientific personnel is to be assembled, with the relevant supporting technical personnel, no country can afford to leave 50% of the population-the half that consists of women-out of scientific, technological, and mathematics education. It is imperative that many more women study physics if the country is to move forward and have the critical mass of scientists needed for economic growth.
