About the author
Ernie Dainow was fascinated with mathematics at an early age. In university he became more interested in how people think and he began graduate work in psychology. The possibilities of using computers to try to understand the brain by simulating learning and thinking became an exciting idea and he completed a Master's degree in Artificial Intelligence in Computer Science.
Ernie's interest in doing research shifted to an interest in building systems. He started working for Univac, the company that had built one of the first general purpose commercial computers. This began a long career in the computer field, working on large mainframe computers and then personal computers, doing software development for academic/scientific research, business and financial applications, data communications, computer hardware products and the Internet.
Ernie never lost his fascination with computers. After he retired he began writing to explain many of the interesting things he discovered over the years that are not well known outside of the computer field.
