Be it the importance of a wheel, or anatlatl, a telephone or an aircraft, every single invention that hs been included in this text has given new insights into the life humans have lived so far, and to a considerable extent, shaped up their lives as well. This is considering that there have been thousands of inventions in the past that have contributed to the history of civilisation in some form or the other. Indeed, the most prominent of inventions are still remembered as ‘life changing’ inventions today, and in fact, harness themselves into more modern forms as we keep up the process of evolution.
