School of Physics and Technology of University of Kharkiv now being carried by the department. The department is considered to be the most difficult department at the school. Students of the department study special courses on elementary particles, quantum electrodynamics, general relativity, astrophysics, theoretical nuclear physics, solid-state theory, and plasma physics. In addition, the professors of the department teach most of the bachelors-level mathematics and theoretical physics courses at the school. The department was created in 1937 by Anton Valter. The name of the department changed several times: "Department of Physics of the Atomic Nucleus", "Department of Physics of the Atomic Nucleus and Electronics", "Department of Electronic Processes", "Department
Atomic physics be reached by excitation by light — however there are no such rules for excitation by collision processes. One of the earliest steps towards atomic physics was the recognition that matter was composed of "atoms". It forms a part of the texts written in 6th century BC to 2nd century BC such as those of Democritus or Vaisheshika Sutra written by Kanad. This theory was later developed in the modern sense of the basic unit of a chemical element by the British chemist and physicist John Dalton in the 18th century. At this stage, it wasn't clear what atoms were
