Do Electrical Engineers hand-write those giant schematics?
When I look at the huge device schematics, there are all types of wires and components everywhere. It looks like a big maze. Are people actually hand-writing those things? I'm thinking about majoring in electrical engineering and the circuit schematics look really intimidating. In my high school Physics class, we draw out simple circuits, but nothing like those.
They are only intimidating because you don't understand them yet.
Once you know enough to see the groups of components that work together to do something, they start to make sense. At present, it's the equivalent of you looking at a book written in say Arabic, compared with one written in English, and probably not even realizing that "page 1" is at the back of the book, not at the front :-)
They are drawn using computer software, but humans still have to design them and check them. They don't just appear by magic.
Actually, the really scary bit in the real world is the first time that somebody is going to actually make whatever it is you just drew. That's when you find out that making a mistake has more consequences than just losing you a few marks in an exam.... ;-)
But don't worry about it. it's just part of the process of learning to be a "real" engineer :-)
