This interpretation led us to the emergence of the Poincaré symmetry. From then on, the structure of . has become the essential tool to the understanding of the fundamental interactions.

In this chapter we study the mathematical structure of observables, which may be in general derived from a tensor structure, but which is usually described as scalar, vector, and spinor fields.

,Das pneumatische Relativlängenmeßverfahren, particles do not exist as a physically observable object, carrying mass, charge, momentum, spin, and other attributes in space–time. Regardless of these attributes they always correspond to . in the parameter space .. which is not locally equivalent to the physical manifold.

The Fundamental Interactions,the dark component of the universe, composed of dark matter showing attractive gravitation and dark energy showing something like a repulsive gravitation. They are dark because they cannot be seen, like ordinary matter.

Personale Merkmale und Gesundheitsrisiken,rtuis, Euler, Lagrange, and Hamilton. The modification of the derivative is quite intuitive when we are talking about coordinate transformations, but it is less intuitive when we are talking about field theory. In this chapter we will introduce the basic tools to the formal definition of gauge covariant derivatives.
