Book Description
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.

Book Description
Written by a leading expert on comets, this textbook is divided into seven main elements with a view to allowing advanced students to appreciate the interconnections between the different elements. The author opens with a brief introductory segment on the motivation for studying comets and the overall scope of the book. The first chapter describes fundamental aspects most usually addressed by ground-based observation. The author then looks at the basic physical phenomena in four separate chapters addressing the nucleus, the emitted gas, the emitted dust, and the solar wind interaction. Each chapter introduces the basic physics and chemistry but then new specific measurements by Rosetta instruments at comet Churyumov-Gerasimenko are brought in. A concerted effort has been made to distinguish between established fact and conjecture. Deviations and inconsistencies are brought out and their significance explained. Links to previous observations of comets Tempel 1, Wild 2, Hartley 2, Halley and others are made. The author then closes with three smaller chapters on related objects, the loss of comets, and prospects for future exploration. This textbook includes over 275 graphics and figures – most of which are original. Thorough explanations and derivations are included throughout the chapters. The text is therefore designed to support MSc. students and new PhD students in the field wanting to gain a solid overview of the state-of-the-art.

Book Description
Analyzing the phase transition from diffusive to localized behavior in a model of directed polymers in a random environment, this volume places particular emphasis on the localization phenomenon. The main questionis: What does the path of a random walk look like if rewards and penalties are spatially randomly distributed?This model, which provides a simplified version of stretched elastic chains pinned by random impurities, has attracted much research activity, but it (and its relatives) still holds many secrets, especially in high dimensions. It has non-gaussian scaling limits and it belongs to the so-called KPZ universality class when the space is one-dimensional. Adopting a Gibbsian approach, using general and powerful tools from probability theory, the discrete model is studied in full generality. Presenting the state-of-the art from different perspectives, and written in the form of a first course on the subject, this monograph is aimed at researchers in probability or statistical physics, but is also accessible to masters and Ph.D. students.
