Who the F cares--Why in the hell are they putting out a NINTH edition? The publishers just put out the the eighth edition, and I've had several faculty people tell me that there was not enough difference between the seventh and eighth to make it worthwhile to use the eighth....and now a ninth?
The name of the book is "Fundamentals of Physics"--not "Cutting Edge of High Particle Physics, So We Have to Keep Putting Out New Editions to Include New Information."
The ONLY possible reason for putting out numerous editions of good textbooks for basic science is to screw undergrads, who then can't either buy used books nor sell their books back to incoming students.
If there REALLY is some NEW and EXCITING and CAN'T BE MISSED info, then Wiley could at least publish a supplement, instead of a whole new edition.
Wiley and it's parent company should be ashamed of themselves.
