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...

Now is the Future

October 21, 2015

We all know the Back to the Future trilogy, right? I’m sure it’ll have come to your attention that today is the day which the Marty McFly and Doc Brown went forward to in Back to the Future Part 2. 4:29pm on 21st October 2015, to be exact. Although the vision of the films was...

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...
