Humans have always looked to nature for inspiration to solve problems. The present development is exalted with, two important events we have to remember one is apparent diversity of nature and the second one is questioning nature of man about the diversity of nature, which had reviled so many fundamental and microscopic unifying facts of nature. For example when we consider varying lengths of fingers of our hand its length variations is apparent and at microscopic level all fingers are constituted with same type of molecules. This elucidation provides an idea that apparent diversity provokes the questioning and promotes man to search the microscopic truth for diversity.
With these microscopic facts unifying principles of nature are evolved.
One of the early examples was the study of birds flying, which had inspired man to enable human to flight. Although never successful in creating a "flying machine", Leonardo da Vinci (1452–1519) was a keen observer of the anatomy and flight of birds, and made numerous notes and sketches on his observations as well as sketches of various "flying machines. The Wright brothers, who finally did succeed in creating and flying the first airplane in 1903, also derived inspiration for their airplane from observations of pigeons in flight. Otto Schmitt, an American academic and inventor, coined the term biomimetics to describe the transfer of ideas from biology to technology. The term biomimetics only entered the Webster’s Dictionary in 1974 and is defined as "the study of the formation, structure, or function of biologically produced substances and materials (as enzymes or silk) and biological mechanisms and processes (as protein synthesis or photosynthesis) especially for the purpose of synthesizing similar products by artificial mechanisms which mimic natural ones." In early history of scientific philosophy, there was a professed
