I'm going to be writing a series of articles on specifically HVAC&R physics that might last 12 months, maybe 24 or maybe even beyond 36 months. I will write the first one, the intro, this Friday. The idea is that by the end of the series any level 3, 4 or 5 tech who says he/she does not understand all the physics and formula used in HVAC&R will no longer have any valid excuse. No lecturer should ever after say they have no easy to understand material to teach thermodynamics (including PH charts and Psychrometrics) or fluid dynamics etc with/from.

The articles will be published in the ACR Today magazine - I make no money out of writing these articles - I just get to enjoy a few more hours a month thinking

Does anybody have any ideas about what of physics they would like to read about?

Is physics easy but boring? Is it interesting but too difficult? Or are there other opinions/perceptions?
