From the time of its awakening, a curious human mind was trying to understand all secrets of creation and realize obtained knowledge in practice. Nowadays, it may seem that first steps on this way took an inadequate period and that this elementary knowledge about physics and geometry were received with a great delay. This opinion is not completely correct. Of course, we cannot be sure that elementary measuring devices, such as pendulums and gnomons have been used in the Neolithic Period or during the building of ancient megaliths, such as Stonehenge or Ring of Brodgar. A modern archaeology papers format takes into account only verified archaeology findings, so we just cannot affirm with great confidence that these incredible structures were built with the help of these tools. Nevertheless, scientists proved that ancient Egyptians created and actively used first exemplars of pendulums in daily practice. Unfortunately for all humankind, their progressive technologies were not included in further industrial practice. The next stage of scientific development was realized only at the end of the saturnine Middle Ages. Famous Galileo Galilei discovered principles of classical mechanics using ordinary ticker as an object of study. Speaking about the history of a pendulum, we also cannot help but mention classical glorious experiments performed by Newton and Foucault that changed the image of contemporary science. Students must not be astonished to discover that some of commonly used models of pendulums are named in honor of these brilliant scientists and philosophers, such as Foucault’s pendulum and Newton’s cradle. They are still used in schools and specialized universities worldwide in order to demonstrate basic rules of classical mechanic and fundamental laws of nature, such as the law of conservation of energy and essential laws of non-relativistic physics. Moreover, a great amount of problem solution essay topics concentrates on principles of study based on these elementary scientific tools.
