Cult such as National Socialism, Communism, or Islam don't create. Faiths do. Faiths use reason to assess, promote and investigate science creating a platform for metaphysics. Science will never explain the 'whys' of the physical world. Why is there gravity ? Why does the earth rotate at 1000 miles hour ? Why not at 100.000 miles per hour ?

Islam created very little. This is obvious from any objective, sentient reading of history. Only in astronomy is there any evidence of originality from Moslems or Islamic philosophers. Within the Moslem world from the irruption of the Meccan cult's Jihad in 632 AD until today; precious little that was created by Moslems. Persians, Christians, Jews, Berbers and others within the Moslem empires and occupied areas certainly did create some tangible additions to human knowledge, but that is in spite of, not because of, Islam.

Why didn't the Moslems for example invent the Wind Mill ? Hiero's 1rst century AD wind power engine was known to the ancients. Instead of destroying the extant minor libraries available; and allowing goats and pigs to lay waste to the soil; why didn't the Moslems improve on the science which was founded in Alexandria, after they conquered the area in 640 AD ? Why didn't some Moslem 'scientist' use Hiero's wind-mill model as a basis for further innovation ?

Why indeed didn't the Moslems invent anything that was innovative, scientifically, or mathematically premised ? Outside of some minor astronomical improvements the Moslems were simply squatters on richer civilizations, transmitting ancient knowledge to Europe, some of it novel, some of it known, some of it already rejected. It is a catastrophe that for 1000 years Moslems denuded, degraded, slaved, warred and destroyed much of the North African-Eastern and North-Eastern Mediterranean world; and extended that devastation into Eastern Europe, Russia and Central-Western Africa.

Islam's world-view, parametrized by the Koran, is negative, Jihadic, irrational and denies free-will. It is the exact opposite of Christianity.

Freed from Rome circa 500 AD many European regions began a long process of rebuilding. The Church was at the center of this re-civilization. In England in 500 AD there were no water mills, by 1000 AD there were more than 8.000. The same is true of windmills. Windmills were developed in areas bereft of fast flowing water. By 1200 they were common across Europe, since extant texts lament the loss of timber to build these towering structures. European wind-mill design was unique, specialized and particularly intelligent to harness both wind, and later water-power.  In fact, some 30.000 windmills were built in Medieval Europe - a rather staggering testimony to its wealth and creativity.  

Terry Reynolds in 'Stronger than a Hundred Men' gives an impressive overview of both water and wind mill technology [here]. It is hard to imagine the brains, the energy and the perseverance to establish thousands of such devices across a variegated topography.

On the plains and the coasts varieties of mills were deployed, employing different blades, angles, gears, levers, and varying in intent and objective. Most were used to grind and crush grains and corn. Many of huge stature were utilized in the 'Low Countries' to drain sea water and reclaim land. Only in Christian-medieval Europe were windmills of many varieties developed and deployed for the benefit of the average person. A marked increase in food production and arable land suitable for human settlements proceeded apace.

The Dutch were particularly skilled in wind-mill development. A wind mill to pump out water was invented in Holland circa 1282 AD. By 1550 the Dutch had reclaimed hundreds of miles of land from the sea, building dykes as the windmills helped drain and reclaim the land. Dykes themselves are a formidable medieval invention [see here]. In fact almost half of the present-day Netherlands is from land reclaimed during the medieval period. If you ever have a chance to visit a working model of a Dutch windmill you should take the opportunity and wonder at the internal technology of ropes, gears, balances, weights and measured mathematics – not to mention building skill – that makes up such an impressive piece of technology.

Nothing like the above can be found in the Moslem world.
