Today we are going to talk about something that still causes, not only confusion, but a fair amount of controversy. 

That in itself is amazing because it is a mystery that started about 300 years ago and hasn't really been solved yet. People have been arguing about this for over 300 years! 

Today's subject of interest is wave particle duality. This is also one of the few talks were I'm going to stick an equation in. I'm only doing this because I stumbled across it a while back and I don't know what it means, if anything. I'll throw it in later.
