ABSTRACT
Human civilization has evolved from cave dwelling to modern-day city living. During the course of evolution, humans learned trades, improved their skills, and refined their living standards. A key ingredient for this evolution is the understanding of science and applying the scientific findings to improve the living standards of humans. On their way to early evolution, humans learned how to farm, use wheels, make tools, and so on, which permanently changed the way early humans lived. Since, new discoveries in science continue to change the lives of humans.
