What was invented in Central Asia?
Many of the world’s most useful inventions come from Central Asia: sewing, leather, cart wheels and spinning wheels, burning coal. And then also the compound and recurve bows, saddles and stirrups, and high quality steel.
A lot of important knowledge comes from Central Asia too: that some diseases are contagious, what causes fevers, and astronomical observations.
Central Asia was a clearinghouse for new ideas
When did they invent sewing?
The earliest invention that we know of from Central Asia was sewing. People in Central Asia probably started to sew clothes about 45,000 BC, and invented sewing needles about 40,000 BC. Probably around 5000 BC, they invented leather.
When did they invent the wheel?
They made these first wheels out of solid wood, which may have seemed more convenient in the north where there were more trees, and on the flat grasslands where a cart could move more easily. Soon people in West Asia and China started to use wheeled carts too.
Scythians – and maybe other Central Asians too – used marijuana as a medicine, and to relax. They built a ring of stones for a fireplace, and then set up a small tent of wooden poles and woolen mats over the fire, and threw weed on it and breathed in the smoke. (We know about this from Herodotus, and also from archaeological finds.)
New kinds of hunting bows
When people in Central Asia started riding horses, about 2500 BC, they also invented the compound bow, a kind of bow and arrow that was shorter, so you could shoot it while you were riding your horse. Around the same time, they also domesticated camels to ride.
The spoked wheel
By 2000 BC, the people of Central Asia could make better wheels: they invented the spoked wheel. Wheels with spokes were stronger and lighter and used less wood than solid wheels.
Burning coal to heat houses
The recurve bow, saddles, and stirrups
Sometime around 1000 BC, Central Asian archers invented the recurve bow. This bow was shaped like a W, and it was shorter, but it could shoot further. Recurve bows were easier to use while you were riding your horse.
Then around 200 BC, people in Central Asia invented saddles and stirrups for their horse equipment. Saddles and stirrups made it much easier to ride and fight from horses. Around 800 AD, Central Asian farmers may also have invented the horse collar, so that horses could plow fields.
Central Asian science and the Silk Road
Once the Silk Road connected Central Asian traders with China and West Asia (and Europe), Central Asians got much richer than before – rich enough to pay for great libraries and universities.
The scholars at these universities invented many new things. The most important was crucible steel, a better kind of steel, harder and more flexible.
Central Asians also started manufacturing glass at Kuva (Uzbekistan).
Doctors and medicine in Central Asia
These scholars also worked on improving medicine. As early as the 400s BC, a doctor did surgery on a man’s throat at Subashi in what is now western China and stitched the wound shut with horsehair.
The Armenian doctor Mkhitar Heratsi encouraged doctors to keep patients in quarantine to keep diseases from spreading, and discouraged bleeding patients. Like Maimonides at the same time, Mkhitar thought clean air, good food, and exercise were the foundations of health.
Russian ice-breaker boats
Although many Central Asian inventions have to do with horses, by the year 1000 AD Central Asian people were also using boats, and Russian boat-builders invented an early ice-breaker boat, the koch. The koch had a rounded body under the water so it wouldn’t be wrecked if it hit ice, and also had ice-resistant wood planking at the waterline.
Central Asian astronomy
In the later Middle Ages, under Mongol rule, Central Asian scientists started to do a lot of good astronomical observations.
In 1256 AD, Nasir al-Tusi convinced Hulegu Khan (a grandson of Genghis Khan) to build him a big observatory in Azerbaijan.
Ulug Beg’s observations
In 1420, the Mongol astronomer Ulugh Beg, a grandson of Timur, built a great astronomical observatory in Samarkand, in order to take more accurate measurements of the movements of the planets and stars. He got more accurate measurements by building a really huge sextant with a radius of about 36 meters.
With this sextant, Ulugh Beg made a list of 994 visible stars. That was more stars than anyone else had ever seen, and with more precise locations than ever before. Ulugh Beg was also able to figure out how long it took the earth to go around the sun, with an accuracy to within 58 seconds. He also measured the tilt of the Earth’s axis at 23.52 degrees, which was more accurate than anybody else had ever done. To make these calculations, Ulugh Beg also calculated trigonometric sine and tangent tables accurate to eight decimal places.
