Dedicated to promoting academic exchange and education in the humanities and sciences, Academia Sinica regularly holds popular science lectures, such as the monthly “Knowledge Feast Lecture” and the “Lectures in Honor of Former Presidents”. To enlarge our audiences, we have compiled the articles from these lectures into the Knowledge Feast Series. The newest volume, Knowledge Feast Series IX has recently been published by Academia Sinica. This book consists of 12 articles and covers a variety of fields in popular science. It is available at the list price of NT$360 (at the Sifen Bookstore). TEL: (02) 2652-1876
