Thanks to everybody in PHYS420 for their honest criticism and suggestion

Thanks to Mr. Vincent Tang from University Hill Secondary School for letting me present to his class.

Thanks to Jason, Don, Mits, Sam and Matt for hanging around in the lab, so I feel less miserable.

Big thanks to the guys down in Machine Shops: Ernest for the course, Matthew, Keith and Dieter for helping me getting the material. Lastly and mostly thanks to Nick for always teaching me new tricks to work more efficiently with the machines.

I got some ideas from some websites, but I'm too lazy to list them now..
