Electronics is a science, and a very
accessible science at that. With other areas of scientific
study, expensive equipment is generally required to perform
any non-trivial experiments. Not so with electronics. Many
advanced concepts may be explored using parts and equipment
totaling under a few hundred US dollars. This is good,
because hands-on experimentation is vital to gaining
scientific knowledge about any subject.
When I starting writing Lessons In
Electric Circuits, my intent was to create a textbook
suitable for introductory college use. However, being mostly
self-taught in electronics myself, I knew the value of a
good textbook to hobbyists and experimenters not enrolled in
any formal electronics course. Many people selflessly
volunteered their time and expertise in helping me learn
electronics when I was younger, and my intent is to honor
their service and love by giving back to the world what they
gave to me.
