A free undergraduate textbook on quantum theory, suitable for a first course.
Fundamentals of Quantum Theory is a book for a first undergraduate course in quantum theory guided by the following principles:
-
The latest edition of this book will always be accessible for free.
-
The printed version will be as affordable as possible. To ensure that, we won't charge any royalties.
-
We hope this book can become a community effort through your feedback as a student or a teacher. This will be crucial for improving the material for everyone. We thank very much all those who will take the time to write to us at fundamentalsofquantumtheory@protonmail.com
Concerning the book:
-
It does not shy away from the conceptual challenges from the get-go, without being overly technical.
-
It has a focus on theoretical aspects, without being overly mathematical.
-
It presents the general structure of quantum physics, without getting boggled-down in the details of applications that require years to master (you’ll specialize later).
-
It invites you to question, not to accept received authority.
-
We believe students should be encouraged to study quantum theory from a myriad of perspectives - no single resource is perfect for every student, including this one. We tried to write a book we would have liked to read as undergrads.
