Frank H. Shu (University Professor Emeritus, University of California (UC), Berkeley, USA) is one of the world’s leading authorities in theoretical astrophysics and star formation. He has made contributions that have brought about paradigm shift in the understanding of how stars and spiral galaxies form. His pioneering work on the origins of stars over a span of 30 years has generated a comprehensive and widely accepted theory that explains the main events in the birth and evolution of a star. His textbook, The Physical Universe: An Introduction to Astronomy, has been widely used by both undergraduate and graduate students for 30 years.
