greatest humanity inventions?

The invention of the Electricity by T. Edison contributed a lot in wellbeing and prosperity of human kind.

The wheel is regarded as one of the oldest and most important inventions, which is, according to most authorities, originated in ancient Mesopotamia in the 5th millennium BC, originally in the function of potter's wheels. Records show that wheels appeared almost simultaneously in Mesopotamia and Europe. The wheel reached India with the Indus Valley Civilization in the 3rd millennium. In China, the wheel is certainly present with the adoption of the chariot in ca. 1200 BC, and Barbieri-Low (2000) argues for earlier Chinese wheeled vehicles in, from maybe 2000 BC.

Although they did not develop the wheel proper, the Olmec and certain other western hemisphere cultures seem to have approached the concept, as wheel-like worked stones have been found on objects identified as children's toys dating to about 1500 BC. The wheel was apparently unknown in sub-Saharan Africa, Australia, and the Americas until relatively recent contacts with Eurasians.

A spoked wheel on display at The National Museum of Iran, in Tehran. The wheel is dated late second millennium BCE and was excavated at Choqa Zanbil.The invention of the wheel thus falls in the late Neolithic and may be seen in conjunction with the other technological advances that gave rise to the early Bronze Age. Note that this implies the passage of several wheel-less millennia, even after the invention of agriculture.

Early wheels were simple wooden disks with a hole for the axle. The oldest such wheel was found by the Slovenian archeologist dr. Anton Velušček and his team in 2002 at the Ljubljana Marshes (Ljubljansko barje), some 20 kilometres southeast of Ljubljana, Slovenia.[1] According to the experts in Vienna, Austria, the specimen was manufactured somewhere between 3350 and 3100 BC and is even older than others of such kind found in Switzerland and Germany.

In the early Roman empire, most horse-carts used a design featuring two chords across the wheel.[2] The spoked wheel was invented much more recently, and allowed the construction of lighter and swifter vehicles. The earliest known examples are in the context of the Andronovo culture, dating to ca 2000 BC (see chariot). Celtic chariots introduced an iron rim around the wheel in the 1st millennium BC. The spoked wheel was in continued use without major modification until the early 20th century.

The invention of the wheel turned out to be of great importance not only as a transportation device, but for the development of technology in general, important applications including the water wheel, the cogwheel (see also antikythera mechanism), the spinning wheel, the astrolabe or torquetum. More modern descendents of the wheel include the propeller, the jet engine, the flywheel (gyroscope) and the turbine.

The central importance of the wheel also resulted in its becoming a strong cultural and spiritual metaphor for a cycle or regular repetition (see chakra, reincarnation).

In July 2001, the wheel was the object of an innovative, but non-inventive, patent as a "circular transportation facilitation device".[3] The patent was obtained by John Keogh, a lawyer from Melbourne, Australia, with the declared intention of demonstrating the unfairness and inaccuracy of the modern patent system.
