I'm at my second year of mechanical engineering, and I do like all the theoretical stuff I'm learning (calculus, linear algebra, physics). But the problem is: when it comes down to actually build something, I find much more interesting to assemble and solder circuits than building something really mechanical(electronics is a hobby of mine). I'm not much mechanically inclined, besides loving various aspects of mechanical engineering: thermo, fluids, aerodynamics. Also, I enjoy learning about control systems. I find their mathematical nature very interesting, and I'm taking some online courses on this subject. Which fields of mechanical engineering do you think would suit me?
