| | China: where the new and the historical materialism interact 423
Although scientists in China are being forced into a new role by rapid changes in Chinese life and closer contacts with the West, they are still guided by Marxist philosophy and the principle of social relevance. In the first of three articles on developments in Chinese science policy over the past year, Tong B. Tang, describes the organisation of research. In future articles, he will discuss higher education and the popularisation of science.

| | Energy: the need for technical fixes 425
Model-based predictions of energy demand and supply are unreliable, since the behaviour of individual producers and consumers cannot be guaranteed. Alvin M. Weinberg (right) of the Institute for Energy Analysis at the Oak Ridge Associated Universities, Tennessee, argues that technical fixes involving increased supply offer the most reliable way of averting an energy crisis
