The characteristics of the process of pursuing universality appeared in the paper on the special theory of relativity.

The beginning of the pursuit of universality (Why) The content of universality (What) The method of pursuing of universality (How)
An asymmetrical problem that occurs when Maxwell’s electrodynamics is applied to moving bodies 1. Frame-independent laws of physics
- Principle of relativity
: In all reference systems for which the laws of dynamics hold, the laws of electrodynamics and the laws of optics also hold.
1. Pointing out specific defects in existing knowledge of physics - An asymmetrical problem that occurs when Maxwell’s electrodynamics is applied to moving bodies
The reciprocal electrodynamic action of a magnet and a conductor
- The observable phenomenon
: depends only on the relative motion of the conductor and the magnet
- Customary view
: the clear difference occurs depending on which object is moving
2. Frame-independent physical quantities
(invariants)
- Principle of the constancy of speed of light
: light is always propagated in empty space with a definite velocity which is independent of the state of motion of the emitting body.
2. Accepting existing physics knowledge that should be universally respected.
2-1. Principle of relativity
2-2. Maxwell’s equation→ speed of light is constant
3. Object-independent laws of physics
- The transformative formula from kinematics also applies to electrodynamics.
3. Making the new argument a universal one that everyone will naturally accept.
- The principle of relativity applies equally to the law of electrodynamics and the law of optics.
