10–70 AD) created the first steam engine.[2] In China, Zhang Heng (78–139 AD) improved a water
clock and invented a seismometer, and Ma Jun (200–265 AD) invented a chariot with differential
gears. The medieval Chinese horologist and engineer Su Song (1020–1101 AD) incorporated an
escapement mechanism into his astronomical clock tower two centuries before any escapement can
be found in clocks of medieval Europe, as well as the world's first known endless
power–transmitting chain drive.[3]
During the years from 7th to 15th century, the era called the Islamic Golden Age, there were
remarkable contributions from Muslim inventors in the field of mechanical technology. Al–Jazari,
who was one of them, wrote his famous Book of Knowledge of Ingenious Mechanical Devices in
1206, and presented many mechanical designs. He is also considered to be the inventor of such
mechanical devices which now form the very basic of mechanisms, such as the crankshaft and
camshaft.[4]
Important breakthroughs in the foundations of mechanical engineering occurred in England during
the 17th century when Sir Isaac Newton both formulated the three Newton's Laws of Motion and
developed Calculus, the mathematical basis of physics. Newton was reluctant to publish his
methods and laws for years, but he was finally persuaded to do so by his colleagues, such as Sir
Edmund Halley, much to the benefit of all mankind.

Using the principles of flight the Wright brothers flew the first successful airplane
that they named the "Wright Flyer" in Kitty Hawk, North Carolina during the year of
1903. It flew a distance of approximately two football fields until landing
("Milestones of Flight"). Since the age of the Wright brothers, aerospace in itself has
grown substantially from ballistic missiles to satellites. The key principles of flight,
discovered by early engineers helped modern engineers nearly perfect design
and scrape the surface of fixed winged aircraft's full potential. Thus pushing
engineers to extend their reach into the vastness of space far beyond what Orville

In modern times the Internet is the most widely used method of
communication, its not common that people would want to know about how the
internet actually works, most would just rather click and receive instant access to
the world wide web. In terms of engineering one could consider the following
hypothesis to be logical; aerospace engineers design satellites making them durable
enough to withstand the debris in space surrounding the Earth's atmosphere as well
