Nature is made up with Chinese Knots
However, we will tell you one that is even more astonishing. How about the hypothesis that Nature itself is made up with these knots? We are all taught that there are four fundamental forces in the universe: gravitational, electromagnetic, weak and strong forces. For the theoretical physicists, who care a lot about beauty and simplicity in physical theories, this is rather untidy: why four and why these four? Quite recently it was discovered that the four forces are deeply related to four kinds of knots. In other words, it may be that there are four forces simply because there are four ways of making up knots, in a certain mathematical sense. This discovery was published in 1989, and it is still one of the most active research areas in fundamental physics.
As William Blake famously put it: 'To see a world in a grain of sand', and it is certainly true that in the Chinese knot we see a lot of things: the beauty of the knot itself; the man, who made up the knots; and the universe, which may be made of knots! While we are admiring the Chinese knots, let us not forget that all these things: knots, man and the universe are but a small shade of that infinitely magnificent display that is Nature.
