Welcome on our interactive page dedicated to basic problems in experimental atomic physics. This document is meant for high-school students, who are interested in physics, university students of science departments, physics teachers and all who would like to increase their knowledge of this subject.
On this page one can find full descriptions of experiments in world's microstructure physics, which supplied the knowledge of atomic structure on the beginning of the 20th century, i.e. discovery of electron, atomic nucleus and calculation of an elementary charge. One can also come across some other experiments which led to detection of isotopes. These experiments are presented from theoretical point of view (there are mathematics formulas and transformations presented in clear way) as well as practical point of view (exact descriptions of sets of instruments and of the way of carrying out the experiments). Description of discoveries and attainments in world's microstructure physic accomplished throughout two thousand-year-old history of this science development also takes place here. It starts with ideas of Democritus, the Greek philosopher, going on to the thoughts of other atomic scientists of the 16th, 17th and 18th centuries, up to the first half of the 19th century.
An acquaintance with our Internet page is an easy and enjoyable way of introducing our readers to the world of atom.
