My electrical engineering Major basically boils down to Boolean Algebra, Learning how to construct computer networks (both macro IE Internet and micro IE Communications between components within a computer), & microcircuitry. There is a good bit of computer programing as well.
My Mechanical engineering major boils down to Optimization of design through math...
My Minor in Intelligent Robotic Systems deals with Artificial Intelligence, and my Design Project.
So basically a week of classes for me goes like this.
Go to upper-level math class, learn something.
Go to Physics class and apply what I learned in the previous semesters math course.
Go to Engineering class and either apply the math and physics to my field or learn field specific stuff. (like Boolean Algebra)
I plan on starting off working for companies in the Electrical engineering field, then later on starting my own company in the robotics field.
