Title: Irresponsible Author
Review: As a physicist, I've read several physics books published by professors from different countries. It's the first time and it will be the last time I ever buy books published by these Chinese authors; they appear to be quite irresponsible. I found a few "Typo Errors ??" and requested clarification from the authors and publisher. So far they never reply.It also appears that the authors do not quite understand the subjects well enough to come up with a sound solutions to the problems posed in the book. They seem to memorize formulas in physics rather than having a deep understanding like Dr. Richard Feyman or Dr. David Griffith .etc.DON'T BUY THIS BOOK UNLESS YOU HAVE SOME MONEY TO WASTE.
