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 better serve our audiences, we have compiled these lectures into the Knowledge Feast Series. The latest volume, Knowledge Feast Series XI has recently been published by Academia Sinica. This book consists of 11 articles and covers a variety of fields in popular science. It is available at the list price of NT$330 from the Sifen Bookstore. TEL: (02) 2652-1876
