Physics energy are no longer valid. The two chief theories of modern physics present a different picture of the concepts of space, time, and matter from that presented by classical physics. Classical mechanics approximates nature as continuous, while quantum theory is concerned with the discrete nature of many phenomena at the atomic and subatomic level and with the complementary aspects of particles and waves in the description of such phenomena. The theory of relativity is concerned with the description of phenomena that take place in a frame of reference that is in motion with respect to an observer; the special theory
National Laboratory of Atomic, Molecular and Optical Physics spectroscopic databases such as HITRAN. The research of the ion group is focused on trapped molecular ions in the ion traps – relatively new branch of physics. Recent works in this field focus on the production, detection and cooling of the molecular ions. The trapped molecules are subject to spectroscopic investigations and as products/substrates for cold chemistry of single molecules. National Laboratory of Atomic, Molecular and Optical Physics National Laboratory of Atomic, Molecular and Optical Physics (KL FAMO) is the national inter-university research center with the headquarters at Institute of Physics of Nicolaus Copernicus University in Toruń, Poland.
