Searching for the principles of all things

Newtonian mechanics: In 1687, Newton published "Mathematical Principles of Natural Philosophy", proposing Newton's three laws and the law of universal gravitation, which was the first major unification in the history of physics. Maxwell's equations: In 1865, Maxwell published the Maxwell's equations, which unified electrical, magnetic, and optical phenomena into electromagnetic phenomena, and successfully explained the propagation of light, that is, light is also an electromagnetic wave, which is the unity of electromagnetic light. Special Relativity: In 1905, Einstein published the theory of special relativity, which solved the problem of inconsistency between Maxwell's equations and Newtonian mechanics, and proposed that time and space are relative rather than absolute, which is the unity of spacetime. General Relativity: In 1915, Einstein proposed the theory of general relativity, which explains gravity as the curvature of spacetime, achieving the unity of spacetime, matter, and energy. Quantum mechanics: In the early 20th century, the development of quantum mechanics revealed the micro.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Each "door" symbolizes the unity of physical theories in different historical periods, understanding the several unifications and turning points of physical theories, guiding visitors to realize that our current physical interpretation of the world is not yet unified, and at the same time imagining the possibility of a "theory of everything".
