TOP FIVE GREATEST INVENTION OF ALL TIME

here's my 5/6 entry for my Top five portion
TOP FIVE GREATEST INVENTION OF ALL TIME

TOP 5 GREATEST INVENTION OF ALL TIME'

"PRINTING PRESS"




This may seem unimportant, but it truly is. Gutenberg's press, with its movable type, started the idea of publishing oral knowledge or multiplying exissting, hand-written books. This may actually be the reason why so many people turned their backs on Christianity, putting a Bible in the hands of anybody who wanted one. The Church no longer possessed the absolute truth, and thus the independently thinking individual emerged as the key unit of society. In the longer term, publishing universalized literacy.

"COMPUTERS"





Many people have the deepest, richest, most diverse, and rewarding relationship with their computer. It plays games with them, tells them jokes, plays music to them, it does the taxes, and sometimes it' even used to work. AND OFCOURSE I CANT POST THIS ENTRY WITHOUT THE USE OF MY COMPUTER HEHE

"TRANSPORTATION(AUTOMOBILE,AEROPLANE , SHIPS)"

The first earth tracks were created by humans carrying goods and often followed game trails. Tracks would be naturally created at points of high traffic density. As animals were domesticated, horses, oxen and donkeys became an element in track-creation. With the growth of trade, tracks were often flattened or widened to accommodate animal traffic. Later, the travois, a frame used to drag loads, was developed. Animal-drawn wheeled vehicles probably developed in Sumer in the Ancient Near East in the 4th or 5th millennium BC and spread to Europe and India in the 4th millennium BC and China in about 1200 BC. The Romans had a significant need for good roads to extend and maintain their empire and developed Roman roads.
The modern history of road transport also involves the development of new vehicles such as new models of horse-drawn vehicles, bicycles, motor cars, motor trucks and electric vehicles.

In the stone ages primitive boats developed to permit navigation of rivers and for fishing in rivers and off the coast. It has been argued that boats suitable for a significant sea crossing was necessary for people to reach Australia an estimated 40,000-45,000 years ago. With the development of civilization, bigger vessels were developed both for trade and war. In the Mediterranean, galleys were developed about 3,000 BC. Galleys were eventually rendered obsolete by ocean-going sailing ships, such as the Arabic caravel in the 13th century, the Chinese treasure ship in the early 15th century, and the Mediterranean man-of-war in the late 15th century. In the industrial revolution, the first steam ships and later diesel-powered ships were developed. Eventually submarines were developed mainly for military purposes.

Humanity's desire to fly likely dates to the first time man observed birds, an observation illustrated in the legendary stories of Daedalus and Icarus in Greek mythology, and the Vimanas in Indian mythology. Much of the focus of early research was on imitating birds, but through trial and error, balloons, airships, gliders and eventually powered aircraft and other types of flying machines were invented.

"DRUGS (ANESTHETICS, ANTIBIOTICS)
"

In common usage, an antibiotic is a substance or compound (also called chemotherapeutic agent) that kills or inhibits the growth of bacteria. Antibiotics belong to the group of antimicrobial compounds used to treat infections caused by microorganisms, including fungi and protozoa.
With advances in medicinal chemistry, most antibiotics are now modified chemically from original compounds found in nature, as is the case with beta-lactams (which include the penicillins, produced by fungi in the genus Penicillium, the cephalosporins, and the carbapenems). Some antibiotics are still produced and isolated from living organisms, such as the aminoglycosides; in addition, many more have been created through purely synthetic means, such as the quinolones.
Although potent antibiotic compounds for treatment of human diseases caused by bacteria (such as tuberculosis, bubonic plague, or leprosy) were not isolated and identified until the twentieth century, cures for infection were described in ancient Chinese medicine using plants with antibiotic-like properties over 2,500 years ago. Many other ancient cultures, including the ancient Egyptians, ancient Greeks and medieval Arabs already used molds and plants to treat infections.

Anesthesia, or anaesthesia has traditionally meant the condition of having sensation (including the feeling of pain) blocked or temporarily taken away. This allows patients to undergo surgery and other procedures without the distress and pain they would otherwise experience. The word was coined by Oliver Wendell Holmes, Sr. in 1846. Another definition is a "reversible lack of awareness", whether this is a total lack of awareness (e.g. a general anaesthestic) or a lack of awareness of a part of the body such as a spinal anaesthetic or another nerve block would cause. Anesthesia differs from analgesia in blocking all sensation, not only pain. Anesthesia is pharmacologically induced reversible state of Amnesia,Analgesia,Loss of consciousness, Loss of skeletal muscle reflexes and decreased stress response.
THE GREATEST INVENTION OF ALL TIME

"THE USE OF ELECTRICITY"

Long before any knowledge of electricity existed people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BC referred to these fish as the "Thunderer of the Nile", and described them as the "protectors" of all other fish. They were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians
Further work was conducted by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay. In the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. He observed a succession of sparks jumping from the key to the back of his hand, showing that lightning was indeed electrical in nature.

In 1791 Luigi Galvani published his discovery of bioelectricity, demonstrating that electricity was the medium by which nerve cells passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819-1820; Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827

Electricity is an extremely flexible form of energy, and has been adapted to a huge, and growing, number of uses. The invention of a practical incandescent light bulb in the 1870s led to lighting becoming one of the first publicly available applications of electrical power. Although electrification brought with it its own dangers, replacing the naked flames of gas lighting greatly reduced fire hazards within homes and factories. Public utilities were set up in many cities targeting the burgeoning market for electrical lighting.

Electricity is used within telecommunications, and indeed the electrical telegraph, demonstrated commercially in 1837 by Cooke and Wheatstone, was one of its earliest applications. With the construction of first intercontinental, and then transatlantic, telegraph systems in the 1860s, electricity had enabled communications in minutes across the globe. Optical fibre and satellite communication technology have taken a share of the market for communications systems, but electricity can be expected to remain an essential part of the process.
