Re: [Phys-L] Thermal Physics solution manual

[Dan Beeker <debeeker@comcast.net>]

Being a self motivated learner who is generally slower at learning than most others definitely option #2. Put it in the public domain. If one is trying to learn without the benefit of an instructor or classroom setting the solutions will be invaluable. It is invaluable even if one has an instructor and peer support. Even with the solution set (not just answers) mastering the material is still not easy. It is just one more tool. There is much to be learned from looking at problems related to a particular topic. The author’s problem sets are often much superior to a Shaun’s outline (if it exists at all). That’s not to say everything is forthcoming and enlightenment comes with a solutions manual but having such does provide one more resource and gives a minimal check that one has mastered the material if the same or similar answer is obtained.

I can recall many years ago having to teach a course in thermodynamics to a group of first year engineering students. Though there was much I did not understand we got through it. I could not have done it without a solutions manual, nor would my students have survived it. Even with the solutions we would still be confused and would spend hours trying to figure out why the author did the solution in a particular way. There was a lot of learning, albeit not very efficient learning, going on. In this day and age the answers are generally available on what used to be Cramster (a pay site) and many other sites. Why not make them publicly available and as others have said, level the playing field?

The publisher, Pearson, is not interested in reprinting it, but they have offered to post it online as a pdf that instructors could download after logging on with a password.  However, there are other options.  As I see it, the choices are as follows:

Part of me wishes I had never written a solution manual, because its mere existence conveys the message that solutions are things that are handed down by authority (the textbook author) rather than things you should figure out for yourself and think about critically.  On the other hand, many instructors seem to depend on the solution manual, especially when they are pressed for time.

My impression is that Pearson's legal department can make illegal downloading less convenient, but cannot stop it entirely.  If we release a high-quality pdf of the manual, then its distribution in electronic form will become somewhat more convenient.
