The ancient Egyptians are believed to have used a system of surveying the land that was developed through observation of the stars and the changing of the season. By watching the movements of stars and attempting to set a standard that would roughly comply to that which they had observed, the Egyptians were able to construct massive monuments of surprisingly accurate proportions. The Great Pyramids of Ghiza are but one example of this application of standards derived from astronomical observations. Unfortunately, many records of that time have disappeared over the ages, so it is difficult for us to know exactly how they made their measurements. It is, nevertheless, obvious that by relying on the standards that they observed in nature, the Egyptians were able to build long-lasting quality architectural monuments.
The same principle of developing standards through careful observation is essential for modern engineers. For example, to determine the standard load a steel beam can support, it is necessary to identify the composition of the metal in the beam. Such observations are only possible with the aid of microscopic measuring devices. Once a standard has been established for the composition of the beam, further experimentation is performed to find the maximum stress the beam can withstand. Again, such tests are only possible through the development of machinery that can deliver measurable quantities of force. Skyscrapers and large bridges, just like the pyramids of ancient Egypt, can only be built after elaborate sets of standards have been developed.
