If we are still finding ways and means of improving an invention made
over 4,000 years ago, we must realize the tremendous field that lies
ahead in improving more recent inventions. And what is still more
important, think of the opportunities in the field of principles
yet undiscovered. Although man may be very dependent upon this
invention, the fact remains that Nature found other means of travel,
because the animals, the fish and the birds have been moving on
the land, and in the water and air for millions of years. Yet, in all
of her myriad of living creatures, Nature has never used our very
necessary principle of the wheel. ●  |
