Over the last 8 years I took most of the interesting 4th year undergraduate physics courses, and some graduate physics and engineering courses.
Well, my notes for much of that work are now available on amazon.com (or .ca), or for free as PDF. For the bargain price of $88, leveraging the time and money that I spent, you can get very comprehensive paperback notes for these subjects. These notes aren’t textbook quality, but generally contain detailed expositions of the subjects and many worked problems.
Here’s what’s available:
That’s 4814 pages of notes for 0-$USD 88, depending on whether you want a PDF or paper copy (if available). My cost per page is about $4.7 CAD, factoring in total tuition costs of ~$23000 CAD (most of which was for my M.Eng), but does not factor in the opportunity cost associated with the 20% paycut (w/ a switch to 80% hours) that I also took to find the time to fit in the study.
If you compare my cost of $4.7/page for these notes to FREE – $0.024/page, then I think you would agree that my offering is a pretty good deal! While I have built in a $1 (+/- $0.50) royalty for the book formats, the chances of me recovering my costs are infinitesimal.
A few of the courses and/or collections of notes are not worth the effort of making print ready copies, and those notes are available only in PDF form. An exception are my notes for Multiphyiscs Modelling, which was an excellent course, and I have excellent notes for, but I’ve been asked not to make those notes available for purchase in any form (even w/ $0 royalty.)
