Supertheories and Consilience from Alchemy to Electromagnetism Many of us—though not all—believe that good scientific theories are ones that simultaneously explain disparate phenomena. The theory of evolution in Biology, general equilibrium in Economics, and electroweak theory in Physics have all been favored for this property, and the Santa Fe Institute is sometimes rumored to be looking for a unified theory of complex systems. There is no obvious reason why the world should work this way, of course: the best science could well be domain local, a view sometimes found among linguists and anthropologists. We must thus regard unification as an epistemic norm, not a given. When examined from the outside, it is of mysterious origin. It is not to be found in the origin texts of the scientific revolution: Francis Bacon’s introduction of the scientific method in the New Organon is positively hostile to the idea, and it only becomes explicit in 1843 when William named it “consilience”. An analysis of the five thousands articles published in the Philosophical Transactions of the Royal Society, Europe’s first scientific journal, between 1666 and 1867, shows that norms of consilience rose gradually, and inexorably, over the course of two centuries of investigation. Explicit selection for consilience begins in the 1700s, around the time of Ben Franklin’s kite experiments, and by the mid-1800s, we see the emergence of supertheories: ideas like electromagnetism and the wave theory of light that break prior pairwise consilience to accrue links and co-explain a much wider range of phenomena than ever seen before.

The videos in this course are broadly divided into three parts:

🔸 Part 1. Time Independent Perturbation Theory and WKB Approximation.

In this section, we discuss in detail non-degenerate and degenerate time-independent perturbation theory. As an application and illustration of the methods, we study the fine structure of the hydrogen atom as well as the Zeeman effect, both in its weak and strong forms. We develop the Wentzel-Kramers-Brillouin (WKB) approximation, useful for time-independent problems that involve potentials with slow-varying spatial dependence.

🔸 Part 2. Time Dependent Perturbation Theory and Adiabatic Approximation.

In this section, we begin by developing perturbation theory for time-dependent Hamiltonians. We then turn to Fermi’s Golden Rule, and then to the interaction of light with atoms, focusing on the processes of absorption, stimulated emission, and spontaneous emission. We discuss charged particles in electromagnetic fields and derive the Landau levels of a particle in a uniform magnetic field. We study in detail the Adiabatic approximation, discussing Landau-Zener transitions, Berry’s phase, and the Born-Oppenheimer approximation for molecules.

🔸 Part 3. Scattering and Identical Particles.

The final part of the course begins with a study of scattering. We discuss cross sections and develop the theory of partial waves and phase shifts. An integral reformulation of the scattering problem leads to the Born approximation. We then turn to the subject of identical particles. We explain the exchange degeneracy problem and develop the machinery of permutation operators, symmetrizers and anti-symmetrizers. We discuss the symmetrization postulate and discuss the construction and properties of multi particle bosonic and fermonic states.

After developing basic tools to handle parametric models, we will explore how to answer more advanced questions, such as the following:

🔵 How suitable is a given model for a particular dataset?
🔵 How to select variables in linear regression?
🔵 How to model nonlinear phenomena?
🔵 How to visualize high-dimensional data?
