It altered the face of continental Europe and the condition of the inhabitants. The forests began to disappear as assarting cut deeper into the woods. Because the plough is the instrument of surplus it means that the farmer - for the first time - could produce more than he needed so he was able to sell his surplus. That freed other people - doctors, carpenters, etc - from growing existence crops. They could now buy their produce with the money they made pursuing their trade. Because people no longer had to move around to gather food, they settled in villages that eventually became cities. The plough has been around much longer than any of the scientific objects mentioned above - the earliest illustrations comes from a book of psalms written in England in the fourteenth century - but whether or not you would call it a scientific object may be debatable. Certainly it was a breakthrough in the fourteenth century - an object still very much in use today. |

| 781646 | 2009-06-15 10:35:00 | The plough . The plough is the instrument of surplus . . . . Certainly it was a breakthrough in the fourteenth century - an object still very much in use today . Sorry, not an invention, just a horse accessory - without the horse the plough was too hard for the farmer's wife to push . ;) |

Quite true. There was once a TV series called 'Connections' by James Burke which followed the links between small discoveries and inventions and how they led onto larger inventions. Many of the inventions listed are the result of many other key discoveries or inventions fitting together to make a larger impact. |

| 781649 | 2009-06-15 23:14:00 | With reference to Roscoe's nomination of the plough as a great invention, it was the development of the horse collar, as replacement for the girth surcingle used in earlier times which made efficient farming practices possible. It enabled draught horses to replace oxen as they were much faster. The collar meant that the animal could in effect, push the load, rather than drag it. Weight pulling studies The French cavalry officer Lefebvre des Noëttes experimented with the ancient throat-and-girth harness in comparison the later trace breast-harness and the finally the matured form of the medieval collar harness. In his experiment of 1910, he found that two horses (aided by effective traction) using the throat-and-girth harness were limited to pulling about 1100 lbs. (½ ton).[7] However, a single horse with a more efficient collar harness could draw a weight of about 1½ tons.[7] (Wikipedia) |

The device which enabled mechanical power to replace animal power was the change that made many of the other inventions possible . Some, such as the Ford changed modes of transport, and eventually made populations more mobile, but contributed nothing to sea transport or even to air transport . Think of the advances in manufacturing using steam power that made so many more developments possible . Wow, it's huge . It wasn't called the Industrial Revolution for nothing! The steam engine was truly the invention that changed the world . . . permanently, for ever!!! C'mon SJ, give me some support here . I too have often thought that this huge brain of mine was not designed to view the back end of a mule . Unfortunately, I only see all the inventions - so they are called - as extensions of things that already existed in a simpler and even a gentler form . Steam engine? Feet Telegraph? Voice see? And REFRIGERATION was not even mentioned . |
