Dealing with Blank Lines Comments in Fortran READs

September 4, 2017

Just a quick little programming snippet today. When preparing data files, it’s often useful to include headers and comments in them, especially in the more complicated ones. Most data applications that you might be loading data into, such as maybe Python or MATLAB, have plenty of ability to filter out those comments, but what if...

Beginning with BibTeX – Making Referencing in LaTex as Easy as Pi

August 14, 2016

[mathjax] It’s no secret that physicists love using LaTeX to write papers. This has many practical advantages, such as the ability to completely unlink your content from the formatting, very flexible layout tools and a veritable smorgasbord of packages to do everything from change the colour of your text to allow you to programmatically create plots...

Once Again, With More Soul

March 22, 2016

In my free time of late, I’ve been busy beavering away on my latest website. This one has taken a few weeks to perfect and hone but this is the brand new website for my band Soul Traders. This has been coming for a little while, and when you see the old site you’ll understand why. It’s...

Using Wintersmith to Make Awesome Static Websites

December 3, 2015

For the last month or so, I’ve been deeply investing my spare time into writing a website for a conference, the UK Exoplanet Community Meeting 2016, or UKEXOM 2016 for short. Early on we decided that the best way to host it would probably be to use Amazon’s pretty nifty S3 service. This comes with...

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...

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...

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...

A Little Digital Audio Rant

November 17, 2011

Hi All, it’s that time of the year again. Time for a good ol’ rant from yours truly. This time I’m ranting about digital audio. In particular, music downloads and CDs. Personally I just can’t get my head around why someone would rather buy MP3s / AACs off of iTunes or any other miscellaneous MP3...

We Discovered an FUor

December 20, 2018

We discovered a very rare kind of star – in fact there are only 25 stars of its type known to exist. The fact that we found it is amazing, but the way we found it was even more interesting. We caught it red handed during an FUor outburst – a period of intense flaring...

About Me

August 12, 2018

I am a postgraduate observational astrophysicist, currently working in the astrophysics group at the University of Exeter. Under the supervision of Professor Tim Naylor, my PhD project involves understanding fundamental parameters of low-mass stars. Previously, I completed an MPhys, also at the University of Exeter, studying the way that interstellar dust interact with light, an...

Remember to look up at the stars and not down at your feet: A tribute to Stephen Hawking

March 14, 2018

There are a couple of books I can honestly say inspired me to be an astronomer. In college, junior / senior year in high school for those in the USA, I had absolutely no idea what I wanted to do after I’d finished my A-levels. However, years of watching Star Trek and vivid memories of...
