The measurement of time is a fascinating subject, Superficially simple and commonplace, it develops more and more complexity the more you look into it. In learning what I needed to know to design a sundial, I found myself delving into the subject and often frustrated that the information I needed […]

For some reason, there have always been some aspects of Quantum Mechanics which I’ve found it hard to get to grips with, not for the usual reasons ( weirdness, macroscopic superposition &c), but simply because some of the basic mathematical consequences of the framework are neither obvious nor typically explored […]
An awful lot of confusing stuff is written about quantum measurement, decoherence, bell’s theorem, etc. etc. I don’t have any answers, but I do at least want to capture the right questions. What are the issues and non-issues We all know that quantum systems behave differently from classical ones. We […]
A state function of a system in equilibrium is a macroscopic value which is a pure function of the state of the system. So, for example, we know that any two samples of the same quantity of a specific gas at given temperature and pressure will occupy the same volume. […]
