If you find an error, please let me know. There seems to be an unending supply of them. As one author described it brilliantly, “the hand is still writing though the brain has long since disengaged.”
Also let me know if you find points that are unclear to the intended readership, mechanical engineering graduate students with a typical exposure to mathematics, or equivalent.
The same for sections that cannot be understood without delving back into earlier material. All within reason of course. If you pick a random starting word somewhere in the book and start reading from there, you most likely will be completely lost. But sections are intended to be fairly self-contained, and you should be able read one without backing up through all of the text.
General editorial comments are also welcome.
