Thought-leaders contributing to this volume include Piyush Gupta, Laurence Liew, Lee Tzu Yang, Geh Min, and more!This volume comprises essays by Singapore thought-leaders republished from various issues of the annual journal of the National University of Singapore Society called Commentary.The chapters have been curated to provide historical review of Singapore's journey in economic, ecological and social development. Centred around the theme of sustainability, together, they provide a rich account of how the issues of environmental management and human resource development were pursued in tandem with strategic industrial policy from the early days of independence.They also convey how the current plans to take the country into the age of the Industrial Revolution 4.0 of digitisation and artificial intelligence, to continue to be the hub of hubs in the new economy, cannot and must not be at the expense of ecological health and a strong sense of stakeholdership among Singaporeans. The issues about immigration in the face of demographic decline, the choices in the sources of energy to power the economy in a carbon-constrained world, and the competition that a small state must continue to respond to as new growth sectors reshape the global economy are tackled by the eminent thought-leaders who contributed the chapters.While this is not new material, the reader will be surprised by how the debates about the policy choices and the expressions regarding what is important for Singapore and Singaporeans to achieve true and enduring national wealth remain fresh in this highly accessible edited book.

In May 1986 a two-day workshop on Physical Processes in Comets, Stars and Active Galaxies was held at the Ringberg Castle near Lake Tegernsee, and this rather unusml. l collection of topics needs a few words of explanation. When we first thought of organizing a workshop on such a large variety of astrophysical objects our main motivation was to honor Rudolf Kippenhahn and Hermann Ulrich Schmidt on the occasion of their 60th birthdays, and we planned to cover at least a fraction of their fields of active research. We then realized immediately that despite the fact that the objects are so different, the physical processes involved are very much the same, and that it is this aspect of astrophysics which governed the scientific lives of both of our distinguished colleagues and friends and allowed them to make major contributions to all those fields. Apparently this viewpoint was shared by many colleagues and it was therefore not surprising that in response to our invitation everybody who had been invited agreed to come and to present a talk. The workshop then turned out to be a real success. In contrast to highly specialized conferences, fundamental problems as well as very recent devel opments were discussed and the participants appreciated the opportunity to exchange ideas.
