Summary

"Students of quantum mechanics are saved trouble if they are not led through all the historical pitfalls, and instead acquainted from the very beginning with concepts, such as spin, that cannot be grasped except by quantum mechanical means ... In this sense the present work is an attempt to present advanced quantum mechanics from an elementary point of view."--Preface
