Book excerpt: This book is a tribute to Professor Yuan-Cheng Fung, the Father of Biomechanics and a pioneer in Bioengineering, in honor of his 90th Birthday. The book consists of articles contributed by his colleagues, students, friends and family. These articles illustrate Professor Fung's profound influence on outstanding leaders in bioengineering, especially biomechanics, and on the life and work of all people who have been in contact with him. The scientific topics covered range from fundamentals of science and engineering (e.g., residual stress, flow dynamics, and cellular signaling) to clinical disorders (e.g., atherosclerosis, diabetes, and hypertension). The articles cover the whole spectrum of biological hierarchy, from genes/molecules to cells/tissues, and organs/systems, with close correlations between engineering and biomedical sciences. This book provides an excellent view of the marvelous contributions of Professor Fung as a Renaissance Man.
