It is believed that the Universe began some 1017 s ago with the creation of “something” from “nothing”. The initial rhythm is transformed into some particles, which are “fundamental”, as we know today and with time those fundamental particles gradually combine themselves to make nuclei, atoms, molecules, galaxies including our Milky Way Galaxy. The first part of the total happening is known as “micro-cosmos” and the last part is “macro-cosmos”. We, human beings of the earth do not have any access in reality to details of both micro and macro cosmos. However, with our intelligence, we have been able to know how the first rhythm manifests itself in different forms in different scales of the Universe as well as in living systems. It is also believed that the same rhythm exists from the total nature around us to every blood cell of the human being. We will focus on different aspects of rhythm in different scales in this eclectic presentation.
