Lecture 7: More on Energy Eigenstates

He is explaining not just so others can understand, but so others cannot misunderstand. Such an approach seems important, given the subject matter. I truly appreciate these lectures.

Quantum Mechanics

It takes something special to re-engage someone long out of the classroom back into a rather abstract study such as Quantum Mechanics, fortunately that is exactly what we are given here. The excitement and wonder is easily felt in the presentation of Prof. A. Adams. As one who is  more than 40 years from university I can only express my thanks for such an opportunity!

Quantum Physics
