Hi, my name is John and I am working on a textbook called Physics Syllabus Stage Six (PSSSix). I have done a draft of chapter 2, Thermal Physics. Although I have requested if this consultation is suitable for this forum, but yet been replied. This textbook is free (online definitely) or not-for-profit (if printed) has 9 chapters and this is the first finished does not have to comply the Australian Curriculum (for high/ secondary school) syllabus, because I am intended to draw the picture of Thermal Physics. However, my concern remains if the content is suitable for such students, and the accuracy of the contents. It would be helpful from your any feedback. In addition, I rather not be used for teaching purposes at this moment since it, although not that possible, has risk to teach with uncorrected textbooks. Since there is no attachment can be provided (it is 11 MB large), I provide the link through http://www.shyjohn.net/ACEPHYSbook2review.pdf [Broken].
