Ok so I've had no sleep last night. I am half bed ridden with the flu, yet I have some compulsory classes this week I must attend. On top of everything I have a maths assignment due Friday on solve partial differential equations using the finite difference time domain method and I have no idea how to do it. Sound bad? Well here's how I feel: I don't think any of my self portraits have ever captured that much emotion . Anyway time to get back. I want this gaussian pulse to move properly before bedtime.
