16 Oct 2021: 3.1.1 Universality Explained. Even before we do any calculations, there are general lessons to be extracted from the framework above. ... β. =. 1. /. 2. is fully compatible with scaling. There’s a more general lesson to take from this.

16 Oct 2021: There is a lesson here: it can be difficult to stare at a metric and get a sense for what you’re looking at.

18 Oct 2021: 3 The Formalism of Quantum Mechanics. 3 The Formalism of Quantum Mechanics. In the previous section we made good headway in building some intuition for simple quantum systems by solving the Schrödinger equation and trying to interpret the results.

18 Oct 2021: 3 Quantum Gases. 3 Quantum Gases. In this section we will discuss situations where quantum effects are important. We’ll still restrict attention to gases — meaning a bunch of particles moving around and barely interacting — but one of the

18 Oct 2021: 1 The Expanding Universe. 1 The Expanding Universe. Our goal in this section is an ambitious one: we wish to construct, and then solve, the equations that govern the evolution of the entire universe. When describing any system in physics, the trick

18 Oct 2021: for . p. odd. There is a general lesson here. Whenever the potential is an even function, meaning.

18 Oct 2021: Statistical Physics by David Tong. 1 The Fundamentals of Statistical Mechanics. 1 The Fundamentals of Statistical Mechanics. 1.1 Introduction. Statistical mechanics is the art of turning the microscopic laws of physics into a description of Nature

18 Oct 2021: It’s not, however, a lesson that we can take and use elsewhere.
