The concept of infinity possessed by snakes is also related to the concept of infinity in mathematics. In fact, the real source of the shape of the mathematical infinite symbol "∞" has not been clarified. The most common saying is that the shape of the symbol comes from lemniscate in geometry, and its English word "lemon" means "ribbon knot" in Latin, so we imagined a simple circular route with a ribbon knot boundary, and then expanded it into a symbol representing infinity.

Another famous explanation is that the symbol of infinity comes from the shape of Mobius belt. It is also based on the surface structure of Mobius belt, which can create infinite circulation routes. But this argument is hard to hold water, because the infinite symbol "∞" appeared earlier than the Mobius belt.

Compared with the above examples, the pattern of ourobosaurus appeared earlier in history, so the relationship between ourobosaurus and infinite symbols is controversial. It is said that "∞" was originally a symbol with religion or alchemy in ancient times. In addition to snakes, the pattern named "endless knot" in Tibetan stone carvings also represents the concept of reincarnation like snakes.

There are still different opinions about the source of infinite symbols because of its vague conceptual boundary and long history. As mentioned above, some people think that "∞" is an ancient symbol, while others think that "∞" is constructed by imagination on a specific object. As for the relationship between "∞" and "∞", it is still inconclusive whether the long-standing "∞" constitutes the image of "" or the "∞" inspired by "Ourath" is used by the mathematical community to express infinity. Besides symbolizing "infinity", Ouroborosaurus also confirmed the concept of the cycle of the universe, which is also reflected in modern physics. The figure of snake reflects a cosmic significance in physics and symbolizes the connection between particle physics (minimum) and the concept of universe (maximum).

According to the concept of physics, matter can be infinitely decomposed into molecules, atoms, particles and other fine units; The more we can understand the movement of the micro-world, the more we can explain the operation law of the whole universe. Because the principle of the integration of yin and yang of life and death of octopus is quite close to the belief principles of "the maximum contains the minimum" and "the minimum can prove the maximum" in physics, it has always been used as a representative symbol of related concepts. In alchemy, the symbol of the serpent is a spell with purifying power. Swiss psychologist Carl? Jung believed that snake was the prototype of everything in alchemy and the "mandala" in alchemy (the energy center of tantric religion). He pointed out:

Those alchemists who have explored nature to a greater extent than this world in their own way, and thus have a deep understanding of everything, use the symbol of a snake biting its tail (referring to the strange phenomenon that snakes hurt themselves) to explain this contradictory paradox. Our hadrosaurs have been accused of symbolizing infinity or everything. In the ancient people's impression, Ouroborosaurus means "self-destruction" and "transformation into a circular pattern", which is a clear message for many keen alchemists, who understand that the basis of alchemy is "original materials". They believe that the snake is a dramatic symbol, which can integrate and assimilate opposites; The feedback obtained through this process of self-unity and contract is eternal life. Because on the one hand, snakes are destroying themselves, and at the same time, they are giving themselves life. It reproduces itself and thus gives itself life. Therefore, Ouroborosaurus symbolizes a principle that exists through conflict with opposites, which is the best interpretation of the first element ... (alchemist) gets a clear answer from other people's vague concepts (meaning that ordinary people's understanding of Ouroborosaurus is often vague and random).

In the early alchemical literature "Cleopatra's Ceratophyllum", there is a famous eye dragon image with the Greek word "hen to pan". Its half-black and half-white image reflects Gnostic dualism. The serpent is a symbol of eternal integration of all things, bringing out the principle of reincarnation of life and death, which is also the field that alchemists have been trying to interpret and liberate. The famous alchemist and physicist Thomas? Thomas brown once wrote a medical paper on human beings, which was full of cases and interesting reasoning. In his letter to his friends, one of them wrote:

The first day should decide the last day, just as a snake's tail should return to its mouth. It is an unusual coincidence that they all ended at the same time of birth.

Brown also hinted at similar information in his article "The Garden of Cyrus" (1658):

Everything has a beginning and an end, so as long as the creator and its mysterious formula are based on the rules of the kingdom of heaven, it will inevitably be reborn.
