Rainbow in a Box

June 23, 2015

Yesterday, I helped out at the physics department with a visit for a local sixth form. The basic idea was that in the morning the groups of students got a tour around the building and then in the afternoon they would get involved in a load of experiments. I was assigned the job of looking after...

About Me OLD

May 26, 2015

I'm a postgraduate astrophysicist working in the astrophysics group at the University of Exeter. My PhD project, under the supervision of Professor Tim Naylor, involves studies of planet forming stars. In this project we hope to be able to observationally study the mechanisms of planet formation around young stars in an attempt to validate current theory. I also...

The Fluid Mechanics of Planetary Atmospheres

February 16, 2015

In my last post I went over a really powerful bit of physics called fluid mechanics, which describes the flow of fluid through a system. The main equation in this framework is the momentum equation; the Navier-Stokes equation.This equation is nye on impossible to solve analytically in it’s full grotesque glory, so in the last post I discussed some of...

Radiative Transfer in Planetary Atmospheres: An Overview

January 1, 2015

A little while ago I got carried away on a little post which discussed a really cool little bit of physics called radiative transfer. As I said then, radiative transfer is a technique that you can use to study how energy, in the form of electromagnetic radiation, moves through material. In that post, which you can...

6EQUJ5 – Decoding the Wow! Signal

December 11, 2014

Nothing quite spikes human interest like a good old fashioned mystery, and the the events at a radio telescope in Delaware, Ohio in 1977 could qualify as just that. The voluntary radio astronomer on duty, Dr. Jerry Ehman, noticed a signal that has gone down in history as one of the great puzzlers of the...

Dust in the Ointment

October 18, 2014

It’s nice every now and then to have a slight reminder why your work is valuable. At the moment I’m part of a research team, working in the astrophysics department at the University of Exeter,  that are studying dust. I know exactly what you’re thinking, how interesting can dust be? The truth is that interstellar...

Gambling with Statistics – Monte Carlo Methods

July 20, 2013

Hey all! In my recent work I’ve been using numerical simulations involving radiative transfer, which basically  means transferring energy via radiation such as light; in the form of photon packets. The way these simulations are run is via a method known quite widely in the physics world called ‘Monte Carlo Methods’. It took me a...

New Years Day Star Trek Marathon – 2012

January 1, 2012

Hey all, as has been a tradition for me for many years, I must have a Star Trek marathon. It just has to happen. I generally do this on Christmas Eve Eve, but owing to being confined to a hospital bed after an operation that day, it was not an option. So, I decided to...
