Structure of Matter From Biophysical Point of View

Author: Katarína Kozlíková

The lecture „Structure of Matter From Biophysical Point of View“ is aimed to give a brief introduction to some applications of physics at microscopic level in medicine. It explains the fundamental problem of science, gives an overview of important stages in structure analysis, explains different structure and forms of matter, physical interactions, general properties and characteristics of matter, Heisenberg uncertainty principle, basic properties of elementary particles, the principle and usefulness of Schrödinger equation.

Radioactivity

Author: Katarína Kozlíková

The lecture „Radioactivity“ is aimed to explain basic terms as radioactive isotopes, natural and artificial radioactivity, law of radioactive decay, half-life of decay (physical, biological, effective), mean life-time, activity and connected formulas and physical units.
