What engineering course is the best?

  1. May 22, 2015 #1
    Electrical engineering,
    Communciations engineering,
    Civil engineering,
    Mechanical engineering.

    My question is how hard are these courses, what do they do in these courses and what jobs can they lead to. I dont really care about salary, i want a job where it is interesting, i have an interest in taking things apart seeing how they work how a process occurs both in mechanical objects and nature (i watch alot of documentaries). I have an interest in technology mainly mobile phones, tablets, computers. Dont know if this would help but im ok at science and math just poor at english literature.

    I'm an electrical engineer, so my bias is disclosed.

    Electrical engineering is highly mathematical and gets very abstract. If you really like math, then electrical engineering is great.

    Electrical engineering is also a broad field with a bunch of fields within it. You have analog circuit analysis and design; digital circuit analysis and design; digital signal processing, microprocessors; FPGAs; semiconductor physics; electromagnetics, RF and microwave circuits, and antennas; information theory; power; controls engineering; motors, and generators; radar; computer architecture; computer network devices; etc., etc.

    All electrical engineers have (or should have) some familiarity and command of the frequency domain, Fourier transforms, and Laplace transforms. Euler's identity is what makes electrical engineering possible: e^(j*omega*t) = cos(omega*t) + j*sin(omega*t), where j = sqrt(-1).

    Mechanical engineering is obviously much more mechanical. Statics, dynamics, thermodynamics, fluids, materials science, mechanics of materials. Newton's laws, analysis of trusses, analysis and design of machines with lots of moving parts, F = ma, finding the acceleration of moving objects that are onboard devices that are undergoing both linear and rotational motion and acceleration, work-energy theorem, heat transfer, conservation of energy, engine analysis and design, entropy, automotive engineering, biomechanics, finite element method, vibrations, selection and design of materials for various products or systems, etc.

    At my alma mater (Letourneau University), all engineering majors had to take certain core engineering courses. We all had to take CS 1 (C++ programming), electrical circuits I (circuit analysis, Ohm's law, Kirchoff's laws, transient analysis of RL and RC circuits, frequency response of circuits), statics, dynamics (F=ma), thermodynamics, materials science, machine tools lab, welding lab, etc. The advantage of this is that I got a broad education. The disadvantage is that I didn't take as many focused courses in electrical engineering. (I actually managed to get my bachelor's degree without taking DSP for example).

    I'd say take a broad range of match, physics, and engineering courses the first two years of college, and then start to focus on whatever you are interested in. If you want to specialize in something, you can do that in graduate school if you have the time, money, opportunity, and motivation.
