Query: Packed with errors

We chose this book as textbook in an introductory course in Microsystems (bachelor level course). What a terrible mistake! The content of the book seemed to be exactly what we needed, but the book is full of errors, especially when trying to deal with basic science as physics and chemistry. We had to create a long list of correction of errors, in order not to fool our students. As it stands, the book is useless.
