Arrange them j ust right, and you have a computer The computer does what you say millions of times a second Reconnecting to the real world Media Theory Practice BASIC ELECTRONICS ELECTRICITY IS LIKE WATER Media Theory Practice BASIC ELECTRONICS LEVELS OF UNDERSTANDING How much do you need to know? To own a car you do not need to understand the details of internal combustion engines, but the details leak out : gasoline, oil, batteries To do electronics you dont need a degree in materials science or solid state physics, but the details sometimes leak out : voltage, current, Ohms Law, etc. This session and the next are what we think youll need to know to begin to have an intuitive grasp over the field of electronics.
