It is equal to the duration of 9,192,631,770 periods of radiation of Cesium-133 in ground state.
Note: Technological and efficiency. The spread of high-speed Internet access, the development of multimedia technologies makes distance learning full and interesting. It can be considered more effective than traditional, because visual information is more vivid, dynamic and memorable. A large volume of educational material is easily assimilated thanks to multimedia. The most common objection to the distance learning system is that students should master most of the material themselves, by reading electronic lectures, while no reading can replace a live communication. But let’s ask ourselves: do distance lectures always lose their full time? In the university he was already answered: no. Teachers made significant work on the preparation of distance courses, and it turned out, It is much more difficult to write a meaningful lecture course with a system of test assignments or create a video lecture than to prepare for a traditional lecture. Preparation of training materials for remote use systematizes both the structure of lectures, and methodological support of the educational process.
