When you start progressing on the path of knowledge, you will notice a strange pattern - your old beliefs will be most of the time an exact opposite of new knowledge. This is quite amusing and enlightening. Everything you "knew" gets reversed gradually. I call this - the flip !
As you progress, your views go on flipping and soon the entire picture changes, the foreground becomes the background, and the background jumps forward. This is the figure-ground reversal that you will notice. We will take up some examples to demonstrate this. What's the point? Well, besides fun, it can be a good indicator of your progress. More things you flipped, more you have progressed. What's your score?
