This book answers the question: 'how do we do all that amazing stuff with computers?' by going beyond explaining how computers work, to talking about how we use the things that computers do to invent new things and to make all kinds of wonderful things happen. Along the way, the reader will get a glimpse into the inside story of how we got to where we are with computers, get an understanding of how some of the 'tricks' are done, clear up a misconception or two, and get insight into where things are going and what is possible.
