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...

My Research

My research interests span astrophysics and environmental intelligence. My astrophysics research currently focusses on better measuring the characteristics of stars from large, cutting-edge photometric and astrometric datasets. I also apply this knowledge to the analysis of datasets for a large variety of environmental sources, from satellite observations to measurements of animal beahviour, to better understand...

#InternationalWomensDay

March 8, 2015

You may have noticed that today, Sunday 8th March 2015, is International Womens Day. This sounded like an ideal time to write about some exceptional scientists whom I greatly admire; who just also so happen to be women. Rosalind Franklin The Woman Who Discovered the Structure of DNA The discovery of Deoxyribonucleic Acid (DNA) is the...

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...

Some Fluid Mechanics Basics

January 23, 2015

At the moment I’m intently studying fluid mechanics for an exam on planetary science. As you may have guessed, the fluid mechanics in question is for modelling planetary atmospheres, but the mathematics is universally applicable. I’ve wanted to learn fluid mechanics for many years so I thought I’d just go through some of the basics...

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...

The Basics of Radiative Transfer

April 28, 2014

It’s deep in exam season for me at the moment, which means that if you try talking to me, chances are that I’ll have my head in a book. I talked a while back about solving radiative transfer problems with Monte Carlo methods, but I never actually went very far into how radiative transfer works....

My New Project – Axe Engine

October 25, 2013

Despite being deep into the 3rd year of both a physics degree and deep into a masters project, I’ve decided to try something quite ambitious. For ages, I’ve wanted to try my hand at writing a 3D game engine, and until now I’ve had neither the confidence or the knowledge to carry off such a...
