General Information
Physics deals with basic principles that apply in the universe and the physical world and it looks for the answers to questions about the basic science. The physicist tries to explain physical events in the universe, such as logic and experiment uses two basic tools. The aim of physics is a quantitative science, based on correlations between the measurable characteristics of matter and energy, to explain all the phenomena in the physical world. These current physical laws in the universe are known as the basic relations. These laws and many events are produced by applying the general expressions Laws must be defined as the necessary features for developing quantitative measures. In this case, the purpose of the employment of basic physics, mathematical language to express the correlations. Nowadays the physics usually requires interdisciplinary studies and critical role in the progress and technology all have almost the entire history of science this trigger parts.

NQR/NMR Laboratory
NQR technique, with kuadrupol (i.e. non-global) is one of the core (especially valans elektronlarının) produces loads of neighboring Crystal electric field (CEF) is based on the gradyentinin electrostatic interaction. Crystal electric field of a nucleus is divided into levels of energy. Transitions between these levels of radiofrequency causes electromagnetic field. The value can vary in the range of a few kHz to hundreds of MHz radiofrequency and depends on the type of the item with the kuadrupol kernel. Transitions such as the person's fingerprint corresponds to the NQR spectrum, any chemical compound has its own characteristic feature. Therefore, quadrupole resonance, the crystal structure provides many of the solid matter to be established.
NQR, particularly illegal substances (drugs, explosives) is to enable the determination. 14N is the core of providing drugs and explosives detection. Almost all known explosives, drugs and even some drugs have nitrogen structure. These items, as well as a 400 kHz – 5.5 MHz NQR signals are in the frequency range.
