The solitary wave is no longer lonely

Keen to end the solitude of solitons, I've been simulating what happens when two or more are collided. Its pretty awesome and have even managed to make a few animations- although Charlie and I are still debating about exactly what happens when you collide these guys.
The image shows the collision of two solitons, notice how they interact non-linearly. The small oscillation waves on the surface are instabilities in the program which I've since fixed by using a sweet RK4 method for time discretisation.
The last two weeks have been a complete geek-out working on this project, but frankly I'm enjoying it. Deadline Friday.
So why have I updated my blog mid-project when I'm spending most of my time in the computing suite or drinking coffee on Level 8? Gav has promised to update his blog twice daily which is highly exciting, but also means I really should raise my game. Although he hasn't today, so maybe I don't need that much more game.

Surfing the Soliton Wave

Another day, another day attempting to model solitons for my computational physics project. This course really is becoming a way of life.
Incidentally, in a humiliating u-turn I've changed the comment settings to allow anonymous posting so that the well known Simon Simpson can share his views. Even with anonymous posting I'm sure it won't be difficult to pick out Simon's characteristic comments.
