> Once again, we don’t have a satisfying explanation why. We know that these quantum numbers correspond to standing-wave solutions of a three-dimensional wave function that we pulled out of thin air. We also know that the model works better than any alternatives. But we don’t know what any of it really means — or if it means anything.
It is so refreshing to see this explicated thus; physics textbooks are generally coy about "know this for now, and there will be deeper insights available later" but they typically never level with readers and say "we don't know".

This was the book used by MIT in 2007 for the first course in the EE and CS programs. It is that year's course that is on their Open Courseware platform [1], and the readings list there links to a full PDF of the book.
(Edit: click the book title on the readings page, not the "View e-book version" link. See my response to groos' comment below for details).
This is not a link to a pirated copy BTW. Agarwal is a pioneer in the open-education movement and the authors intentionally arranged for an open access PDF.
The lecture videos on Open Courseware are very good too.

Always enjoy reading the blog posts, and this seems like a great way to support work that gives me joy. Who knows, might start picking up actual electronics as side projects. Hardware work seems like such a great way to get code into the physical world.

Oh yes, these kinds of shortcuts have always worked great.
