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...

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...

XRT-C Dish Mounting Video is Finally Here!

February 8, 2018

This one has been a long time coming. The XRT-C project has likely seemed a little bit quiet of late, but never fear, as there’s always stuff going on in the background, even if it is only me. Ever since the build day in April 2016, I’ve been working on a video of the day...

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...

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...

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...

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...

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...
