In class yesterday, I was mentioning the concept that in order to learn new things, you have to first understand how your current knowledge falls short, and how it might be misleading you. In this case, I think a picture is worth a thousand words.
Leo Lionni wrote a book called "Fish is Fish" (it makes a great present for nieces and nephews!) In the book, two fish were friends, only one wasn't a fish--he was a tadpole. In time, the tadpole grew legs and became a frog. He told his fish friend that he was going to go up on land to explore, but he would report back.
When the frog came back he told the fish about the interesting things he had seen, and he described them to the fish. Frog saw things with black and white spots and horns that ate grass, and this thing is called a cow. Here is what the fish saw in his mind's eye, based on that description:

and then he described people, walking around and wearing clothes:

We always build new knowledge on top of old knowledge. I think the most significant moment of learning is when we realize we were partly WRONG before, as well as partly right. SO you could say that the most important part of learning new things is the "Epic Fail." Before you can say "Ah HA!" you have to first say "Uh-oh..."
Can you think of a time when this happened for you?
