A Brief History of Looking

In 1687 Sir Isaac Newton published his Law of Universal Gravitation. Was it a result of the famous (even if not really recorded) event of an apple falling down from a tree he was sitting under, or was it a result of a long process of observing how objects, whether they are in space or on earth, behave? No one can really tell for sure. One thing is clear, though: no person on the face of the earth (at least no one we know of) could imagine a force such as gravity exists, although apples were freely falling from trees since the dawn of time.
