��The Brief About Maths�� I like to think about the first humans, the people who came up with the idea to count things. They must have noticed right away that figuring on your fingertips works great.

Perhaps Og (a typical ancient cave guy) or one of his pals or associates said, “There are one, two, three, four, five of us here, so we need five pieces of fruit.” Later, “Hey, look,” someone must have said (or grunted), “you can count the number of people at the campfire, the number of birds on a tree, stones in a row, logs for a fire, or grapes in a bunch, just with your fingers.”

It was a great start. It’s probably also how you came to first know numbers. You’ve probably heard that math is the language of science, or the language of Nature is mathematics.

Well, it’s true. The more we understand the universe, the more we discover its mathematical connections. Flowers have spirals that line up with a special sequence of numbers (called Fibonacci numbers) that you can understand and generate yourself.
