Is statistical thermodyanmics worth taking if your an ME?

[Topher925]

I'm an ME grad student in the thermal fluids area and a lot of my work involves electrochemistry, a little bit of inorganic chemistry, and optics, along with fluid and energy transport (fuel cells and stuff). I'm considering taking a statical thermodynamics class this fall to help me better understand things like energy of reactions and the production of entropy on the micro level. My other option is to take a combustion course mostly covering the thermal science of internal combustion engines which doesn't really relate my research a whole lot.

I haven't taken a physics course since my gen ed intro to EM class I took when I was an undergrad. Would taking ST be a good idea for me since I don't have much of a physics background or would I just find myself overwhelmed by the material?

I was an ME grad student who worked for several years in industry and later went on to a PhD program in materials science. I dare say that for most industry positions, a familiarity with entropy, the Second Law, and ensembles is near-worthless. For continued research in physics or materials science, however, it's vital. Stat mech will teach you the real difference between heat and work, will promote a real understanding of entropy, and (along with kinetics) teach you why any process would occur spontaneously: to minimize energy / maximize entropy. You'll never look at material properties, dynamics, force equilibrium, or the virtual work theorem the same way again.

As an ME grad student in the thermal fluids area, I can understand your dilemma about whether or not to take a statistical thermodynamics class. I believe that statistical thermodynamics is a valuable subject for any engineer, particularly those working in the thermal sciences.

Firstly, statistical thermodynamics is a fundamental concept in understanding the behavior of matter and energy at a microscopic level. This is important for engineers, as many processes and systems involve the transfer and conversion of energy, and understanding the underlying principles can greatly benefit your research and work.

Moreover, statistical thermodynamics has applications in a wide range of fields, including chemistry, materials science, and even biology. By taking this course, you will gain a deeper understanding of the underlying principles that govern these fields, which can enhance your ability to apply your knowledge to real-world problems.

Additionally, taking a statistical thermodynamics course can also help you in your research on electrochemistry and inorganic chemistry, as it deals with the energy of reactions and the production of entropy at a microscopic level. This can provide you with a more comprehensive understanding of these concepts and how they relate to your research.

As for your concern about not having a strong physics background, I believe that with your ME background and your current research focus, you have the necessary foundation to understand and excel in a statistical thermodynamics course. Of course, there may be some challenging concepts, but with dedication and effort, you can overcome them and gain a valuable understanding of this subject.

In conclusion, I believe that taking a statistical thermodynamics course would be a beneficial choice for you as an ME grad student in the thermal fluids area. It will not only enhance your understanding of energy and entropy on a micro level, but also provide you with a strong foundation for your future research and work in the thermal sciences.
