I am an electrical engineer and not a mechanical engineer. As such, I depend on electronic packaging professionals to provide me answers to my thermal questions at work.

This blog post documents my early self-education on how the thermal analysis of electronic components is performed. This post will provide the background necessary for more detailed posts in the future. Continue reading
I was listening to an astronomer on the radio answering questions on viewing stars and planets.

During the presentation, they discussed how ground water can be found that is very old and very hot. I thought I would look into this a bit. Continue reading
