Engineering 101, how hard/easy is it

Engineering is fun provided you know the knack of problem solving. There are different disciplines involved and each of them have their own approach to problems. While I mastered a few of them, I am yet to explore the rest. It definitely takes time to be a complete master of electrical, electronics, mechanical and programming science. Associate each of these areas with the relevant math fundamentals, you get the basics of it. I will describe each and every area in a separate blog provided time permits.
