The common point between modern chemistry and alchemy is to create new things at the molecular level. As for creating new elements, it is actually the task of nuclear physicists. They take some cyclotrons to bombard the new elements and then fill them into the periodic table as chemistry. The fruit of the victory of the family. Classical alchemy actually has elements such as atoms, but does not have rational thinking. For example, medieval Europeans believed that light, heavy, dry, and wet are basic physical properties. Dry and light It is fire, dry and heavy is soil, wet and light is air, and wet and heavy is water. Therefore, any substance is the result of the synthesis of four basic elements: water, fire, soil, and air in different proportions. This is obviously different from the current concept of knowing the world, and the understanding of the nature of matter in other civilizations in the same period is also between mystery and reason.
