World's Wildest Invention Edited(1)

World's Wildest Invention

World's Wildest Inventions By Olayinka Gabriel The world started on a note which could be termed as the stone age where the major constituents of her would include water, stone, sand as well as trees. Man at that time (and even till date) had to live and transform his environment to be more comfortable and condusive for living. This brought about the word and action—invention which is defined as the design or creation of a process or mechanism. This article is bent on discussing the major invention that have proved to be world changers in terms of transformation. The first invention to be discussed is the automobile. The automobile could be seen as the greatest invention from the perspective of a mechanical engineer. The early history of the automobile can be divided into a number of eras, based on the prevalent means of propulsion. Later periods were defined by trends in exterior styling, size, and utility preferences. In 1808 François Isaac de Rivaz designed the first car powered by an internal combustion engine fueled by hydrogen. In 1870 Siegfried Marcus built the first gasoline powered combustion engine, which he placed on a pushcart, building four progressively sophisticated combustion-engine cars over a 10-to-15-year span that influenced later cars. Marcus created the two-cycle combustion engine. The car's second incarnation in 1880 introduced a four-cycle, gasoline-powered engine, an ingenious carburetor design and magneto ignition. He created an additional two models further refining his design with steering, a clutch and brakes. The four-stroke petrol (gasoline) internal combustion engine that still constitutes the most prevalent form of modern automotive propulsion was patented by Nikolaus Otto. The similar four-stroke diesel engine was invented by Rudolf Diesel. The usefulness of automobile in the 21st Century cannot be overemphasized. Would you imagine coming all the way from Lagos to Abeokuta on foot? Another invention that would make the computer engineers, scientists and the entire globe proud is the computer system. This has proved to be really useful to man in diverse ways. Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the "father of the computer", he conceptualized and invented the first mechanical computer in the early 19th century. After working on his revolutionary difference engine, designed to aid in navigational calculations, in 1833 he realized that a much more general design, an Analytical Engine, was possible. The input of programs and data was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter and a bell.
