Internet find Electronics Training from the Navy

United States Navy Electricity & Electronics Training Series - NEETS* In the introduction, the texts are defined as a "self-study course". Seems to be a really good way to teach yourself about electronics if you were so inclined. Another example of how, if you can just filter out the noise, it's possible to get a base education in just about anything if you have access to a web browser. From the intro:

The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical- and electronic-related Navy ratings. Written by, and with the advice of, senior technicians in these ratings, this series provides beginners with fundamental electrical and electronic concepts through self-study. The presentation of this series is not oriented to any specific rating structure, but is divided into modules containing related information organized into traditional paths of instruction. The series is designed to give small amounts of information that can be easily digested before advancing further into the more complex material. For a student just becoming acquainted with electricity or electronics, it is highly recommended that the modules be studied in their suggested sequence. While there is a listing of NEETS by module title, the following brief descriptions give a quick overview of how the individual modules flow together.

The first module - Introduction to Matter, Energy, and Direct Current is 283 pages. Guessing it's pretty impressive learning material.
