This book provides a general introduction to fluid mechanics in the form of biographies and popular science. Based on the authors extensive teaching experience it combines natural science and human history knowledge inheritance and cognition law to replace abstract concepts of fluid mechanics with intuitive and understandable physical concepts. In seven chapters it describes the development of fluid mechanics aerodynamics hydrodynamics computational fluid dynamics experimental fluid dynamics wind tunnel and water tunnel equipment the mystery of flight and aerodynamic principles and leading figures in fluid mechanics in order to spark beginners interest and allow them to gain a comprehensive understanding of the fields development.
