Earth's Shifting Magnetic Field Earth's north pole has been known to be moving ever since the first expeditions located it. In the 20th century, it moved an average of 10km per year, but lately, it's been accelerating to about 40km per year. At this rate, it's predicted to leave Canada and enter Siberia in the coming decades. Not only that, but in the last 100 years, the magnetic field strength has weakened about 10%. Time to sound the alarm? Probably not. Earth is pretty dynamic, and the magnetic field has been known to do lots of crazy things -- it won't stop the doomsayers though!

South Park: Bigger, Longer & Uncut -- This is one hilarious movie -- but boy is it rude. It's rude beyond the point of being offensive. The movie takes the good taste filter off and amuses with humour that simulate the juvenile in us. Every now and again though, that little kid in us needs to be amused -- and this movie will certainly do that. If you're offended by the movie, it's because the adult in you is watching. The Brothers Grimm -- This was an OK fantasy movie, moving at a good pace, with the appropriate level of action and humour. The special effects were well done -- and so was the cinematography.
