Definition of physics

Physics deals with the processes of inanimate nature (with a few exceptions) and their mathematical description.

Physics developed out of people' desire to understand natural phenomena (essentially of inanimate nature), to trace them back to general laws and to make use of nature through this knowledge. In experimental physics, laws of nature are obtained through observation and experience, in theoretical physics through mathematics and logic. Experimental and theoretical physics complement each other in the sense that experimental physics confirms the hypotheses of theoretical physics and theoretical physics uses the results of experimental physics.

Physics is the comprehensive natural science. In the past, it dealt with all aspects of animate and inanimate nature, i.e. with the entire material world. Only later did chemistry and biology emerge as separate subjects. Today, physics creates the link between biology and chemistry, explains the phenomena of energy and matter.

The knowledge of physics about the processes and structure of nature broadens our horizons and makes us aware of our position in the world we can grasp (from the macrocosm of the universe to the microcosm of the elementary particles).
