2. DoD Higher Education Tell them what you’re going to tell them. Tell them what you told them you were going to tell them. Tell them what you told them. Theoretical Minimum: Overview 2

3. The Original Theoretical Minimum Theoretical Minimum: Overview 3 Lev Davidovich Landau, 1908 - 1968 One of the great Russian physicists of the 20 th century Tested prospective students in theoretical physics. 43 students passed, the 2 nd of whom was his famous collaborator, Ilya Lifshitz.

4. Our Theoretical Minimum Theoretical Minimum: Overview 4 Leonard Susskind, 1940- Prominent American physicist at Stanford University: “brilliant imagination and originality” Received many awards and honors (but not yet The Big One) Devotes substantial efforts to a series of lectures aimed at the physics-oriented public
