I'm trying to find an a topic for a physics exploration, and since I like working with computer hardware, I figure I'll try to look at physics related to computer hardware, or electrical/computer engineering in general. However I can't seem to find out what kind of physics goes into this stuff. Perhaps it's just my wording, but Google returns nothing. So, what kind of physics goes into the production of computer hardware, or more generally computer or electrical engineering? Not sure if I can ask this here, but any ideas on how I can create a physics exploration based on these ideas? Thanks for any help/clarification!
