level 0 Tao: elements and interactions

The model which describes all the elementary particles of the matter is known as Standard Model

Including into the Standard Model also the non-elementary particles as molecules, atoms, hadrons and mesons, a complete list of all the elements concerning the physical level of the Universe so far discovered or hypothesized is available.
The interactions between elements are formed by the four fundamental interactions: gravitation, electromagnetism, strong and weak interaction.
