There is a very famous story about Isaac Newton and law of gravity. Once upon a time, Newton sat under an apple tree; and suddenly an apple fall on his head. That’s when he started thinking about law of gravity. Many people believe that the story is not true; but he did think why apple falls to the earth and not to the sky.
Anyway, yesterday we visited Canadian National Exhibition in Toronto. I saw a very interesting show from Daryl Maddeaux. He’s stacking rock on rock without glue, gums, nails or anything. He’s just using the law of gravity. Just look at the picture below. It’s amazing, isn’t it?
This is another picture, which looks impossible.
