Scholar
Welcome to Scholar. This is an experiment in putting lecture notes online.
It's a work in progress and material is being added and improved all the time.

-
A course on quantum measurement theory aimed at MRes and PhD level.
-
The classical theory for oscillations and waves, and an introduction to quantum wave mechanics. Pitched at a second year university level.
-
Exploration of the role of probability in various areas of physics
-
A course on quantum theory, concentrating on the structure of quantum mechanics as a basis of physical theory rather than the quantum physics of particular systems. We take a Hilbert space approach.
-
Exploration of the role of symmetry in physics. Covering topics from the principle of stationary action, Lagrangians, Hamiltonians and Noether’s theorem.
-
The physics and mathematics of rotating systems.

A closer look at prior distributions
-
How do you assign actual values to probabilities?
-
Another of the key tasks of inference is to determine the value of a parameter in a model on the basis of observed data
-
Model comparison is one of the principal tasks on inference. Given some data, how does the plausibility of different models change? Does the data select out a particular model as being better?

In this workshop, we’ll introduce and examine the consequences of probability theory in various areas of physics. From the meaning of probabilities, to how to reason with incomplete information, model comparison, and parameter estimation. The approach will view probabilities as an extension of logic (i.e. following Laplace, Bernoulli, Cox, Jaynes, etc)

Given that we are interpreting probability as a measure of plausibility, just what is the relationship of probabilities to frequencies?
-
Find the probability distribution that maximises the entropy subject to requiring some averages to be fixed.
-
Some consequences of the product rule are explored including the famous Bayes’ rule.
