Mysteries of the Heart
The paper is dedicated to the discovery of mechanisms of circulation and the circulatory system, which was one of the greatest achievements in medicine and physiology. Without this discovery, many medical methods and technologies would have never entered our lives. In 1628, a book Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus by William Harvey was published in Frankfurt. It was a breakthrough in scientific understanding of the functioning of heart in those days. Its author went down the history of science.
