In my first year of undergrad, I was given a great gift.

So…, “so” used as here needs to die.

I don’t know what the future of cybersecurity consulting will be, but I have some thoughts.

AI is not just a buzzword.

An air conditioning device is working on a reverse Carnot cycle between the inside of a room at temperature \(T_2\) and the outside at temperature \(T_1\) > \(T_2\) with a monatomic ideal gas as the working medium.

The Diesel cycle is the thermodynamic cycle which approximates the pressure and volume of the combustion chamber in a Diesel engine.

This is a microcanonical ensemble approach to a simple model of a two dimensional polymer bundle.

This is a microcanonical approach to the problem of the mixture of two ideal gases.

The reason this general problem is so useful in a wide range of areas of physics is in physics we love to deal with harmonic approximations of systems.

The one-dimensional random walk is a key foundational concept in statistical physics which crops up in a variety of situations, albeit normally with far more dimensions.

Question A point particle of mass \(m\) moves in the region \(0 \le x \le l\) and is reflected elastically at the walls at \(x=0\) and \(x=l\).

## A little background to Stirling’s Formula ## Stirling’s approximation is vital to a manageable formulation of statistical physics and thermodynamics.

For the elastic scattering of identical particles, \(A + A → A + A\), what are the Mandelstam variables?

A proton beam with a momentum of \(p=100\text{GeV}\) hits a fixed Hydrogen target (discussion beneath). a) What is the centre of mass energy \(\sqrt{s}\) for this interaction?

Physics Notes, Solutions, and Related Stuff I’ve written up a couple of foundational and a few somewhat challenging physics problems and notes which I think the web could benefit from.

I’ve typed up solutions to a few physics problems often set in BSc. courses, some because they aren’t easily found on the web and I’d like to make the lives of fellow labourers that little bit easier, others are here because by writing them up I was drill…

Recently I returned from a particle physics experiment at the Paul Scherrer Institut, a nuclear research lab in Switzerland.

The Schrödinger equation describes the energy and time-evolution of a particle or system of particles, and is one of the fundamental building blocks of modern physics.

The general Runge-Kutta algorithm is one of a few algorithms for solving first order ordinary differential equations.

I’m getting ready for starting a course in computational physics, and so, ignoring the fact I’m meant to be revising for an exam this Monday, I thought I’d prepare for the more exciting of the two.

Just a quick one here.
