What major courses do you like in your major? Why?

Ha, I have studied both hydraulic engineering and marine science. Let me answer my favorite professional course. Before we begin, let me introduce my hobbies. I prefer theoretical or experimental courses, but have little interest in engineering or planning management courses (such as channelization engineering and project management).

① fluid mechanics

Fluid mechanics is the cornerstone course of all majors involving fluids (such as HVAC, water conservancy, ocean and aviation), and its importance to these majors can be compared with high numbers and big things. Fluid mechanics is one of the important branches of classical mechanics. Its birth can be traced back to Archimedes' time, and it is a basic subject to study the macroscopic movement of fluid. It can be further subdivided into theory of turbulence, hydraulics, aerodynamics and other disciplines. If we want to use fluid mechanics to describe the motion of fluid, the most important thing is to master several key points, such as continuum hypothesis, continuity equation, motion equation, energy equation and boundary conditions, but in the end they can all be reduced to solving various simplified ns equations. Fluid mechanics is a subject that pays equal attention to both theory and experiment, and it also contains many empirical formulas summarized through a large number of experiments. It is interesting to learn fluid mechanics.

② River dynamics and coastal dynamics

These two topics can be introduced together because they are both qualitative description and quantitative analysis. River dynamics and coastal dynamics can be summarized as a subject to study the evolution law and mechanical properties of rivers or coasts after interacting with water flow under the influence of natural conditions and artificial buildings. After studying these two courses, I can say that "looking at water is not water, and looking at mountains is not mountains". I will naturally try to analyze its flow pattern, topographic causes and possible evolution laws in the future, which can greatly improve my cognitive level of the world.

③ Structural mechanics

Different from the above courses, the reason why I like structural mechanics is that it has a strong "playfulness", and writing questions is like playing a game. Structural mechanics is a branch of solid mechanics, which mainly studies the law of stress and force transfer of engineering structures and how to optimize structures. The research object of structural mechanics can be simplified as the deformation and mechanical properties of various components with different connection modes under different stress States. The main solutions are force method, displacement method and energy method. The process of solving problems is interlocking. When drawing the bending moment diagram of the structure and solving the internal force of each member or node, a sense of accomplishment arises spontaneously!

These are my favorite courses. I hope you can also find your favorite course!
