Computers Are Not Magic is a broad but shallow survey of the entire computer phenomenon, from the lowest levels (wires that carry data) to the highest levels (artificial intelligence, animated movies, crypto currency, etc). The goal is to show how everything builds, one layer at a time, to create these incredible machines.
The course has 13 lessons, each 30 to 45 minutes long. The first 5 sessions will offer two lessons each, and the last 3 sessions, which involve more involved topics, will stand alone and offer students extended time for questions.
If you click on the “hamburger” in the upper-right of this web page, you will see notes for a different class that I teach to homeschoolers. The homeschool class has two parts: (1) coding lessons in the Java programming language and (2) “curiosity” lessons about computers. This OLLI class is the “curiosity” lessons without the tedious Java programming instruction.
The lessons move quickly because there's a lot of material to cover. Students are welcome to take notes in class, but it is not necessary—all of the slides are available here for you to view and download. Watch this list, and you will see the link for slides activate a few days before a lesson is given.
