 If we show you a random shape, your eyes will send the information to your brain, which will then decide what to do with it, perhaps not much. If we show you another shape, your senses will again send it to your brain, but now it might be able to find some related information that was stored in your memory. You may have forgotten, but when you were young, you knew nothing. The first time you saw a particular shape, it was meaningless. Over time and in search for order, you started to recognize patterns. One day, someone gave that particular thing meaning. Your mind labelled it as important and decided to store it for future use. Next time you see this or that shape, you might want to pause and pay tribute to the fact that there are more connections in your brain than stars in the universe, here to help you organize inputs, thoughts and memories to get you through life.
