What is the greatest invention of all time, who was the inventor, when and where was it made.?

Answer 1

Eli Whitney's Cotton Gin.

Answer 2

Certainly not the wheel, which wasn't an invention, but a tool adapted for necessity. I think to qualify as the greatest--or even great--the invention should be something which produces the greatest possible good for the long term--that disqualifies the cotton gin, which effectively ensured the continuation of slavery by making it profitable. The printing press is a good choice, because it helped to increase the availability of the Bible to the general public, thereby breaking the monopoly the Catholic Church claimed on spiritual knowledge and easing the onset of the Protestant Reformation. I think, though, that since an educated public is the foundation of a civilized society, I'd have to say that the alphabet--without which a printing press would be just a meaningless contraption; without which we would not even know what to call a "wheel"--is the single greatest invention of man.

Answer 3

of all time? WOW, that's a lot of territory.....

I'll have to go few thousand years back before the printing press and go with the animal drawn plow ( the original wood version) ........it allowed a farmer to turn over soil, plant a lot more seeds a lot deeper than poking a hole on the ground with a stick, the current high technology.......

which substantially increased yields, so one farmer could produce enough food to support three or four or more people who didn't have to be nothing but farmers.......who could then be artisans, scholars , soldiers.....in fact,without the plow we would never have been able to support a population in a city, with all the implications to civilization that implies.....

Answer 4

Printing press, Johann Gutenberg, Germany

Answer 5

Printing press, Johann Gutenberg, 1450, Germany

Answer 6

I would say the wheel...no one knows who exactly invented it, but it's been very important to shaping modern society. Think how different everything would be without it.

Wikipedia: "Most authorities regard the wheel as one of the oldest and most important inventions, which originated in ancient Sumer in Mesopotamia (modern Iraq) in the 5th millennium BC"

Answer 7

Printing press, Gutenberg. I believe it was the 15 century and possibly Germany.

Answer 8

Edison did not invent the light bulb to just made it better. His filament made it last longer.
Best thing the wheel.

Answer 9

The lightbulb. Wasn't it made in like the 1800's by Edison... or something? I don't know.

Answer 10

The artificial heart or cardiovascular surgery. They have saved tens-of-millions of lives.
