Quantum Physics I MIT

 Science
This course covers the experimental basis of quantum physics. It introduces wave mechanics, Schrödinger's equation in a single dimension, and Schrödinger's equation in three dimensions.

Lecture 1: Introduction to Superposition
In this lecture, Prof. Adams discusses a series of thought experiments involving "box apparatus" to illustrate the concepts of uncertainty and superposition, which are central to quantum mechanics. The first ten minutes are devoted to course information.

Lecture 2: Experimental Facts of Life
In this lecture, Prof. Adams gives a panoramic view on various experimental evidence that indicates the inadequacy of prequantum physics. He concludes the lecture with a short discussion on Bell's inequality.

Lecture 3: The Wave Function
In this lecture, Prof. Adams introduces wavefunctions as the fundamental quantity in describing quantum systems. Basic properties of wavefunctions are covered. Uncertainty and superposition are reiterated in the language of wavefunctions.

Lecture 4: Expectations, Momentum, and Uncertainty
In this lecture, Prof. Adams begins with a round of multiple choice questions. He then moves on to introduce the concept of expectation values and motivates the fact that momentum is given by a differential operator with Noether's theorem.

Lecture 5: Operators and the Schrӧdinger Equation
In this lecture, Prof. Zweibach gives a mathematical preliminary on operators. He then introduces postulates of quantum mechanics concerning observables and measurement. The last part of the lecture is devoted to the origins of the Schrödinger equation.
