Hands down--no debate--the greatest invention, the invention that has altered the course of humanity more than any other--is the printing press.  How could ANY of the later advancements have been developed without the power to reproduce the printed word?

Mainly because he represented the European White male oppression of many of the "New World's" inhabitants.  Supposedly, he brought about rapid changes and started the "takeover" of cultures that last to this day.  Therefore, his "discovery" is interpreted by many people to be a repressive, evil point in human history.  Simply put, he represents the original Western World suppression of minority races by white Eurpoean people.

When you ask the question "Who invented electric power?", I presume you mean the electric power distribution that we know of today.\n\nOne of the primary contributors would be Nikola Tesla, a Serbian-American electrical engineer and scientist.  He along with the Westinghouse corporation developed the three-phase AC power distribution used around the world today.  Tesla and Westinghouse corp were also heavily involved in developing new generators and motors using three-phase power.  Edison was trying to promote a relatively inefficient DC distribution system at the same time, but failed to gain widespread support.  Though Edison did create inventions, such as the light bulb, that helped make use of the ever-growing power grid.\n\nI had not heard of Gennai Hiraga before, but sounds like a pretty interesting inventor as well.

man's ingenuity leads to man's destruction...look at where we are going these days...from stone age to the present time...we are happy for how as man we progress in knowledge but "qou vadis tu?" Discovering new things ...wow! Inventing new gadgets...terrific! But where are we heading now? Having instant food...microweave oven...instant drinks...almost everything is instant...are all these things healthwise? Nuclear bombs and modern weapons...what for?\nIs it man's ingenuity or stupidity?

Michael Farday invented electricity as we know it.\nAs a sidenote If Benny Franklin was  a creator of anything it was the lightning rod and the grounding priciple.\nFor centuries electricity has been a challenge to scientists. They have long known that it exists, and have discovered how to generate it on a large scale, but find it difficult to explain exactly what electricity is.\n\nWhere did it all begin?\n\nAround 600 BC Greeks found that by rubbing an 'electron' (a hard Fossilised resin that today is known as Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years, until, around AD 1600, Dr William Gilbert investigated the reactions of amber and magnets and first recorded the word 'Electric' in a report on the theory of magnetism.\n\nGilbert's experiments led to a number of investigations by many pioneers in the development of electricity technology over the next 350 years.\n\nBenjamin Franklin(in his own words)\n Franklin was an American writer, publisher, scientist and diplomat, who helped to draw up the famous Declaration of Independence and the US Constitution. In 1752 Franklin proved that lightning and the spark from amber were one and the same thing. The story of this famous milestone is a familiar one, in which Franklin fastened an iron spike to a silken kite, which he flew during a thunderstorm, while holding the end of the kite string by an iron key. When lightening flashed, a tiny spark jumped from the key to his wrist. The experiment proved Franklin's theory, but was extremely dangerous - He could easily have been killed.\n\nGalvani and Volta\n In 1786, Luigi Galvani, an Italian professor of medicine, found that when the leg of a dead frog was touched by a metal knife, the leg twitched violently. Galvani thought that the muscles of the frog must contain electricity. By 1792 another Italian scientist, Alessandro Volta, disagreed: he realised that the main factors in Galvani's discovery were the two different metals - the steel knife and the tin plate - apon which the frog was lying. Volta showed that when moisture comes between two different metals, electricity is created. This led him to invent the first electric battery, the voltaic pile, which he made from thin sheets of copper and zinc separated by moist pasteboard.\n\nIn this way, a new kind of electricity was discovered, electricity that flowed steadily like a current of water instead of discharging itself in a single spark or shock. Volta showed that electricity could be made to travel from one place to another by wire, thereby making an important contribution to the science of electricity. The unit of electrical potential, the Volt, is named after Volta.\n\nMichael Faraday\n The credit for generating electric current on a practical scale goes to the famous English scientist, Michael Faraday. Faraday was greatly interested in the invention of the electromagnet, but his brilliant mind took earlier experiments still further. If electricity could produce magnetism, why couldn't magnetism produce electricity.\n\nIn 1831, Faraday found the solution. Electricity could be produced through magnetism by motion. He discovered that when a magnet was moved inside a coil of copper wire, a tiny electric current flows through the wire. Of course, by today's standards, Faraday's electric dynamo or electric generator was crude, and provided only a small electric current be he discovered the first method of generating electricity by means of motion in a magnetic field.\nThomas Edison and Joseph Swan\n Nearly 40 years went by before a really practical DC (Direct Current) generator was built by Thomas Edison in America. Edison's many inventions included the phonograph and an improved printing telegraph. In 1878 Joseph Swan, a British scientist, invented the incandescent filament lamp and within twelve months Edison made a similar discovery in America.\n\nSwan and Edi

Galvanization or galvanisation refers to any of several electrochemical processes named after the Italian scientist Luigi Galvani.\n\nit typically means hot-dip galvanizing, a chemical process that is used to coat steel or iron with zinc. This is done to reduce corrosion (specifically rusting) of the ferrous item; while it is accomplished by non-electrochemical means, it serves an electrochemical purpose. \n\n\nContinuously galvanized Wire is produced by passing cleaned steel wire through a lead/zinc bath at high speed ( 180 m/min).\n\nCoating characteristics: Similar to those of continuously galvanized sheet. Coating thickness varies depending on the diameter and coating grade of the wire from 3 microns in the thinnest standard gauge to 43 microns in the thickest (8 mm) heavy galvanized grade.

Big steps forward in knowledge, understanding and the advance of humanity requires great risks to be taken.\n\nWould the pilgrim fathers have set out in a rickety little wooden ship if the same question was asked?\n\nWhat about the dangers of electricity, flying, medical testing? The list is endless and lots of people have died or been seriously injured making the discoveries that have improved all our lives so much.

If I understand what I've read of the term correctly, a technological singularity is what happens when several innovative or radical technologies come together in a way that basically *changes everything* about a civilization.\n\nFor example, James Watt was one of the people who invented the steam engine, so folks knew what pistons moving inside  cylinders were for decades.  Folks knew what assembly-line production was too, as it was first used on Colt firearms in the U.S. Civil War, and Leonardo DaVinci *had plans for a horseless carriage* centuries before anyone knew what a car was....\n\nAnd yet it nearly took until the dawn of the 20th century for all the pieces to gel together in the right way to make cars.  Once that happened, however....\n\nBOOM! that piece of tech changed *everything*, and now we can't imagine America without cars.\n\nThing is, this has been the trend for innovation with us half-wit humans since the dawn of civilization...we get the pieces, sit on them for a bit, and when the time is right, *then* some genius gets them together and changes everything.\n\nBut the trend is on a non-linear, accelerating curve....meaning at some point in the near future, things will accelerate to such a point, and the developed world at least will have *so many* pieces in place that *multiple* "this changes everything" moments just might happen all at once at a rate *unprecedented* in human history.\n\nIt's hitting that point on the curve that most folks are talking about when they say "singularity".  I think.  :S

There was more than one revolutionary social concept developed by the Greeks, and those concepts changed the world:\n\n1. A "public" religion that did not compete with, or replace, private religious beliefs or practices (this was the "glue" that bound together the fiercely independant Greek city-states into a cohesive whole)\n\n2. The concept of natural causes being the explanation for what happens in the natural world (as opposed to divine retribution or reward)\n\n3. The elevation of individuals (excepting, of course, women and slaves) to "citizens'  who participated in public affairs, including law-making\n\n4. Ethics - the idea that there was a way to tell right from wrong without divine authority, decided my rational humans\n\n5. Secular law
