What I’ve Been Listening To – December 2015

January 1, 2016

It’s that time of month again. It’s just ticked over to 2016 in the uphill scramble away from the winter solstice. I present to you my post Christmas romp through the tunes that have been stuck in my head this month. The Cast of Charlie and the Chocolate Factory – It Must Be Believed to...

What I’ve Been Listening To – November 2015

December 1, 2015

And so it’s that time of year again. The nights rapidly draw in after making the exasperated jaunt back from British Summer Time to good ol’ GMT. The fog lies thick over the city as the temperature make it’s downward meander to sub-zero degrees celsius. The feeling of autumn, and indeed shortly after the crisp...

What I’ve Been Listening To – October 2015

November 1, 2015

Yes, I know, I’ve been a little quiet on here lately. To remedy that let’s have a good old fashioned music post. What with now being an office dweller, and occasional observatory dweller too, I’ve had plenty of time to listen to music over the past month. Thanks to Spotify’s excellent discovery features that’s made...

An Undergrad Primer on Vectors

September 7, 2015

[Could not find the bibliography file(s) I wrote a post a while ago with my tips for people that are starting off a physics degree. Just after I published it a friend and fellow post graduate, Sam Cooper, pointed out to me that I made a fairly blaring omission in my summary of undergraduate physics. Vectors. I...

My Top Tips for Preparing for a Physics Degree

August 10, 2015

You’ve just finished your A-levels, you say? Well done, I think you’ve earned a break so go on and enjoy it. However, I wouldn’t mind guessing that at some point in the next couple of months you’re going to get a little bit bored and might even start looking for something to do. If you’re kicking...

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...

University is Over… for Now

June 12, 2015

It is a momentous day for me and rest of the remaining class of 2011 of the University of Exeter’s physics department. Today was our last ever results day. It was also the day where I found out, to my eternal delight, that the last 4 years have yielded a masters degree in physics; an...

My Research

May 26, 2015

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...

Modeling Atmospheres with the Unified Model

February 24, 2015

In my last couple of posts I’ve been going through some of the basic principles of fluid mechanics. From some of the basic approximations that make the equation possible to analytically solve in this post, to some more specialised theory in the context of planetary systems in this post. In these posts we’ve been slowly...

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...
