This article proposes to explain the human cognition in a concise manner for those who are not pundits in the field. Our mind is a very complex mechanism, capable of processing acquired information rapidly and on multiple levels. A good understanding of the details of these processes has been the subject matter of many disciplines. Despite the fact that remarkable results have been obtained by inter-disciplinary studies, cognition is only partially understood. However, the cognitive mechanisms are essentially the same in any domain of knowledge be it mathematics, music, linguistics and so on.
