Course Introduction:
Mechanics and thermodynamics is the fundamental course of the Department of optical information science and technology. In the general technical fields, classical mechanics maintains full activity and takes a fundamental role in theories. So it is very practical. This course introduces the basic concepts, principles and research methods of the mechanics systematically. The students mainly study the basic concepts and principles of particle mechanics, rigid body mechanics, fluid mechanics and Einstein’s special relativity. In addition, this course also talks about mechanical vibration and mechanical wave, lays solid foundation for the follow-up courses.
This course is offered in the second semester.
