Motor car, road vehicle which first appeared in the 19th Century. The first cars were propelled by the steam, but such vehicles were not a success and the age of the motor car really dates from the introduction of the petrol-driven horseless carriages of Gottfrield Daimler and Karl Benz (1885-86). The internal combustion engine for these cars had been developed earlier by several engineers, most notably by the German, Nickolaus Otto, in 1876. The main components of a motor car, from then till now, are a body or chassis to which are attached all other parts - including the engine or power plant, the transmission system for transferring the drive to the wheels, and the steering, braking and suspension mechanisms for guiding, stopping and supporting the car. A few experts assembled the first cars, but Henry Ford and R. E. Olds in the USA began modern mass-production in the early 1900s.

The exact origin of carbon paper is somewhat uncertain. The first documented use of the term "carbonated paper" was in 1806, when an Englishman, named Ralph Wedgwood, issued a patent for his "Stylographic Writer." However, Pellegrino Turri had invented a typewriting machine in Italy by at least 1808, and since "black paper" was essential for the operation of his machine, he must have perfected his form of carbon paper at virtually the same time as Wedgwood, if not before (Adler, 1973). Interestingly, both men invented their "carbon paper" as a means to an end; they were both trying to help blind people write through the use of a machine, and the "black paper" was really just a substitute for ink.

History of Concrete
Timeline
Ancient Egypt
Egyptians used calcinated gypsum to give brick or stone structures a smooth coating.
Ancient Greece
A similar application of calcinated limestone was used by the ancient Greeks.
Ancient Rome
The Romans frequently used broken brick aggregate embedded in a mixture of lime putty with brick dust or volcanic ash. They built a wide variety of structures that incorporated stone and concrete, including roads, aquaducts, temples and palaces.

The dictionary defines an adhesive as "a substance capable of holding materials together by surface attachment." This is a simple definition for a material that is the basis for a multi-billion dollar industry with more that 750 companies competing for a share of the market. It is estimated that 50 of those companies are responsible for 50% of the sales dollars in the adhesive industry

Copper was the first metal used by man in any quantity. The earliest workers in copper soon found that it could be easily hammered into sheets and the sheets in turn worked into shapes which became more complex as their skill increased. After the introduction of bronze, a wide range of castings also became possible. Many of the illustrations on this site serve to show man's progress as a metal-worker, culminating in the priceless inheritance of the Renaissance craftsmen. But copper and its principal alloys, bronze and brass, have always been more than a means of decorative embellishment. Although iron became the basic metal of every Western civilization from Rome onwards it was the copper metals which were used when a combination of strength and durability was required. The ability to resist corrosion ensured that copper, bronze and brass remained as functional as well as decorative materials during the Middle Ages and the successive centuries through the Industrial Revolution and on to the present day.

They were the master farmers of America's Southwest, and engineers of great networks of irrigation canals in the Salt River Valley. They first appeared about 350 B.C., building canals of open ditches, gouged out with stone tools and wooden hoes. The canals spanned almost 250 miles, stimulating trade and commerce between communities of hundreds and thousands of people. No one knows why, whether by climatic upheaval, drought or floods, the Hohokams suddenly vanished in 1450 A.D., well before Columbus discovered America or the Pilgrims landed at Plymouth Rock.

Process Metallurgy is one of the oldest sciences. Its history can be traced back to 6000 BC. Admittedly, its form at that time was rudimentary, but, to gain a perspective in Process Metallurgy, it is worthwhile to spend a little time studying the initiation of mankind's association with metals. Currently there are 86 known metals. Before the 19th century only 24 of these metals had been discovered and, of these 24 metals, 12 were discovered in the 18th century. Therefore, from the discovery of the first metals - gold and copper until the end of the 17th century, some 7700 years, only 12 metals were known. Four of these metals, arsenic, antimony , zinc and bismuth , were discovered in the thirteenth and fourteenth centuries, while platinum was discovered in the 16th century. The other seven metals, known as the Metals of Antiquity, were the metals upon which civilisation was based

Eating in space for John Glenn turned out to be an easy though not too tasty experience. Before the flight, some experts were worried that, in weightlessness food would be hard to swallow and as a result, collect in the throat. Glenn found that eating in space was relatively easy and once the food reached the mouth, there was no problem in swallowing. Other Mercury astronauts following John Glenn were forced to endure bite-sized cubes, freeze dried foods, and semi-liquids in aluminum toothpaste-type tubes. They found the food unappetizing, had trouble rehydrating the freeze-dried foods, and disliked squeezing the tubes. Futhermore, crumbs from the bite-sized cubes had to be captured to prevent them from fouling instruments.

The National Plastics Center and Museum is a non-profit institution dedicated to preserving the past, addressing the present and promoting the future of plastics through public education and awareness. The educational staff has supported this mission throughout the years by conducting hands-on science programming for schools, organizations and the plastics community.
