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...

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...

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...

Lesson Learned from the First Term

January 11, 2012

Today has been the my first exam at university, I’m not going to lie, I’m not very confident about how it went. It seemed like the writer of the paper in question had in-fact decided to almost avoid everything I’d revised. This crippling blow has forced me to look back over my techniques over the...

New Years Day Star Trek Marathon – 2012

January 1, 2012

Hey all, as has been a tradition for me for many years, I must have a Star Trek marathon. It just has to happen. I generally do this on Christmas Eve Eve, but owing to being confined to a hospital bed after an operation that day, it was not an option. So, I decided to...

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...

Random Star Trek Trivia

November 13, 2011

Okay, I think it’s time for a geek out. Here goes. Since I am a massive geek of general sci-fi, and in particular the Star Trek form of sci-fi, time for a little trek related trivia post. The phrase ‘Beam me up Scotty’ was never, ever actually said in the original series, quite ironic seeing...

Happy Birthday @Voyager2!

August 17, 2010

If there’s one thing in modern society which I think is very much overlooked it’s the big black thing above us… no, not the clouds of doubt over the houses of parliament! I means space. Back in the heyday of space exploration everybody was excited about being the first into space, the first to the...
