If you are not really into learning (about) thermodynamics, this book is probably not for you. But if you want to dig into the subject, this is a good book. It’s not for the light-hearted reader. There’s a LOT of information and it’s a really long recording.. I’d really like to listen again someday. I bought the e-book version later, also, so that I can review the equations and concepts. again. Although I have never taken a course on Thermodynamics, I know from comments by Einstein, C.P. Snow and others that it is a core concept needed to have a firm foundation in science and it seems like it is linked to just about all the sciences. Like most audio books that treat mathematical subjects, it leaves something to be desired. If you can, get both the audio book and the print version. If I could have only one, I’d go with the print version.
