#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...

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...

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....

Mini Javascript Hackathon – Tix Clock

July 31, 2013

I’ve spent a lot of time recently writing C++, Python and Shell Script. These languages are great, but I fancied taking a break from them to go back to my old stomping ground. Earlier today I remembered about the existence of a cool little, almost completely useless, piece of geek tech known as the Tix...

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...

Barenaked Ladies – My Alternative ‘Best of’

May 13, 2012

There’s something that has always really bugged me out the music industry; greatest hits compilations. These albums supposedly consist of the best music that an artist has done. However, for the most part I’ve found this to be radically untrue. The way that most of these albums are compiled is by looking at the chart...
