You are almost ready to close this volume and put it on a shelf
or return to the College Bookstore, or…..
Please do not hurry to make this decision.
I hope that this volume was your partner during the semester of challenging
Physics.
I hope it saved your time copying from the board.
It is very important that you made a lot of notes in this book.
You were implicated in the teaching learning process. In some sense
you are a co-author now.
You were helping me find misprints during the semester of our communication
and I will appreciate your final
feedback with a list of misprints so I could fix the next edition of
this book.
Aren’t you keeping this volume for your memory?
