How Islamic inventors changed the world

From coffee to cheques and the three-course meal, the Muslim world has given us many innovations that we take for granted in daily life. As a new exhibition opens, Paul Vallely nominates 20 of the most influential- and identifies the men of genius behind them

 
 

1 The story goes that an Arab named Khalid was tending his goats in the Kaffa region of southern Ethiopia, when he noticed his animals became livelier after eating a certain berry. He boiled the berries to make the first coffee. Certainly the first record of the drink is of beans exported from Ethiopia to Yemen where Sufis drank it to stay awake all night to pray on special occasions. By the late 15th century it had arrived in Mecca and Turkey from where it made its way to Venice in 1645. It was brought to England in 1650 by a Turk named Pasqua Rosee who opened the first coffee house in Lombard Street in the City of London. The Arabic qahwa became the Turkish kahve then the Italian caffé and then English coffee.
2 The ancient Greeks thought our eyes emitted rays, like a laser, which enabled us to see. The first person to realise that light enters the eye, rather than leaving it, was the 10th-century Muslim mathematician, astronomer and physicist Ibn al-Haitham. He invented the first pin-hole camera after noticing the way light came through a hole in window shutters. The smaller the hole, the better the picture, he worked out, and set up the first Camera Obscura (from the Arab word qamara for a dark or private room). He is also credited with being the first man to shift physics from a philosophical activity to an experimental one.
3 A form of chess was played in ancient India but the game was developed into the form we know it today in Persia. From there it spread westward to Europe - where it was introduced by the Moors in Spain in the 10th century - and eastward as far as Japan. The word rook comes from the Persian rukh, which means chariot.
4 A thousand years before the Wright brothers a Muslim poet, astronomer, musician and engineer named Abbas ibn Firnas made several attempts to construct a flying machine. In 852 he jumped from the minaret of the Grand Mosque in Cordoba using a loose cloak stiffened with wooden struts. He hoped to glide like a bird. He didn't. But the cloak slowed his fall, creating what is thought to be the first parachute, and leaving him with only minor injuries. In 875, aged 70, having perfected a machine of silk and eagles' feathers he tried again, jumping from a mountain. He flew to a significant height and stayed aloft for ten minutes but crashed on landing - concluding, correctly, that it was because he had not given his device a tail so it would stall on landing. Baghdad international airport and a crater on the Moon are named after him.
5 Washing and bathing are religious requirements for Muslims, which is perhaps why they perfected the recipe for soap which we still use today. The ancient Egyptians had soap of a kind, as did the Romans who used it more as a pomade. But it was the Arabs who combined vegetable oils with sodium hydroxide and aromatics such as thyme oil. One of the Crusaders' most striking characteristics, to Arab nostrils, was that they did not wash. Shampoo was introduced to England by a Muslim who opened Mahomed's Indian Vapour Baths on Brighton seafront in 1759 and was appointed Shampooing Surgeon to Kings George IV and William IV.
6 Distillation, the means of separating liquids through differences in their boiling points, was invented around the year 800 by Islam's foremost scientist, Jabir ibn Hayyan, who transformed alchemy into chemistry, inventing many of the basic processes and apparatus still in use today - liquefaction, crystallisation, distillation, purification, oxidisation, evaporation and filtration. As well as discovering sulphuric and nitric acid, he invented the alembic still, giving the world intense rosewater and other perfumes and alcoholic spirits (although drinking them is haram, or forbidden, in Islam). Ibn Hayyan emphasised systematic experimentation and was the founder of modern chemistry.
7 The crank-shaft is a device which translates rotary into linear motion and is central to much of the machinery in the modern world, not least the internal combustion engine. One of the most important mechanical inventions in the history of humankind, it was created by an ingenious Muslim engineer called al-Jazari to raise water for irrigation. His 1206 Book of Knowledge of Ingenious Mechanical Devices shows he also invented or refined the use of valves and pistons, devised some of the first mechanical clocks driven by water and weights, and was the father of robotics. Among his 50 other inventions was the combination lock.
8 Quilting is a method of sewing or tying two layers of cloth with a layer of insulating material in between. It is not clear whether it was invented in the Muslim world or whether it was imported there from India or China. But it certainly came to the West via the Crusaders. They saw it used by Saracen warriors, who wore straw-filled quilted canvas shirts instead of armour. As well as a form of protection, it proved an effective guard against the chafing of the Crusaders' metal armour and was an effective form of insulation - so much so that it became a cottage industry back home in colder climates such as Britain and Holland.
9 The pointed arch so characteristic of Europe's Gothic cathedrals was an invention borrowed from Islamic architecture. It was much stronger than the rounded arch used by the Romans and Normans, thus allowing the building of bigger, higher, more complex and grander buildings. Other borrowings from Muslim genius included ribbed vaulting, rose windows and dome-building techniques. Europe's castles were also adapted to copy the Islamic world's - with arrow slits, battlements, a barbican and parapets. Square towers and keeps gave way to more easily defended round ones. Henry V's castle architect was a Muslim.
10 Many modern surgical instruments are of exactly the same design as those devised in the 10th century by a Muslim surgeon called al-Zahrawi. His scalpels, bone saws, forceps, fine scissors for eye surgery and many of the 200 instruments he devised are recognisable to a modern surgeon. It was he who discovered that catgut used for internal stitches dissolves away naturally (a discovery he made when his monkey ate his lute strings) and that it can be also used to make medicine capsules. In the 13th century, another Muslim medic named Ibn Nafis described the circulation of the blood, 300 years before William Harvey discovered it. Muslims doctors also invented anaesthetics of opium and alcohol mixes and developed hollow needles to suck cataracts from eyes in a technique still used today.
11 The windmill was invented in 634 for a Persian caliph and was used to grind corn and draw up water for irrigation. In the vast deserts of Arabia, when the seasonal streams ran dry, the only source of power was the wind which blew steadily from one direction for months. Mills had six or 12 sails covered in fabric or palm leaves. It was 500 years before the first windmill was seen in Europe.
12 The technique of inoculation was not invented by Jenner and Pasteur but was devised in the Muslim world and brought to Europe from Turkey by the wife of the English ambassador to Istanbul in 1724. Children in Turkey were vaccinated with cowpox to fight the deadly smallpox at least 50 years before the West discovered it.
13 The fountain pen was invented for the Sultan of Egypt in 953 after he demanded a pen which would not stain his hands or clothes. It held ink in a reservoir and, as with modern pens, fed ink to the nib by a combination of gravity and capillary action.
14 The system of numbering in use all round the world is probably Indian in origin but the style of the numerals is Arabic and first appears in print in the work of the Muslim mathematicians al-Khwarizmi and al-Kindi around 825. Algebra was named after al-Khwarizmi's book, Al-Jabr wa-al-Muqabilah, much of whose contents are still in use. The work of Muslim maths scholars was imported into Europe 300 years later by the Italian mathematician Fibonacci. Algorithms and much of the theory of trigonometry came from the Muslim world. And Al-Kindi's discovery of frequency analysis rendered all the codes of the ancient world soluble and created the basis of modern cryptology.
15 Ali ibn Nafi, known by his nickname of Ziryab (Blackbird) came from Iraq to Cordoba in the 9th century and brought with him the concept of the three-course meal - soup, followed by fish or meat, then fruit and nuts. He also introduced crystal glasses (which had been invented after experiments with rock crystal by Abbas ibn Firnas - see No 4).
16 Carpets were regarded as part of Paradise by medieval Muslims, thanks to their advanced weaving techniques, new tinctures from Islamic chemistry and highly developed sense of pattern and arabesque which were the basis of Islam's non-representational art. In contrast, Europe's floors were distinctly earthly, not to say earthy, until Arabian and Persian carpets were introduced. In England, as Erasmus recorded, floors were "covered in rushes, occasionally renewed, but so imperfectly that the bottom layer is left undisturbed, sometimes for 20 years, harbouring expectoration, vomiting, the leakage of dogs and men, ale droppings, scraps of fish, and other abominations not fit to be mentioned". Carpets, unsurprisingly, caught on quickly.
17 The modern cheque comes from the Arabic saqq, a written vow to pay for goods when they were delivered, to avoid money having to be transported across dangerous terrain. In the 9th century, a Muslim businessman could cash a cheque in China drawn on his bank in Baghdad.
18 By the 9th century, many Muslim scholars took it for granted that the Earth was a sphere. The proof, said astronomer Ibn Hazm, "is that the Sun is always vertical to a particular spot on Earth". It was 500 years before that realisation dawned on Galileo. The calculations of Muslim astronomers were so accurate that in the 9th century they reckoned the Earth's circumference to be 40,253.4km - less than 200km out. The scholar al-Idrisi took a globe depicting the world to the court of King Roger of Sicily in 1139.
19 Though the Chinese invented saltpetre gunpowder, and used it in their fireworks, it was the Arabs who worked out that it could be purified using potassium nitrate for military use. Muslim incendiary devices terrified the Crusaders. By the 15th century they had invented both a rocket, which they called a "self-moving and combusting egg", and a torpedo - a self-propelled pear-shaped bomb with a spear at the front which impaled itself in enemy ships and then blew up.
20 Medieval Europe had kitchen and herb gardens, but it was the Arabs who developed the idea of the garden as a place of beauty and meditation. The first royal pleasure gardens in Europe were opened in 11th-century Muslim Spain. Flowers which originated in Muslim gardens include the carnation and the tulip.

Muslims and Maths

By Zin Elabidin Derfoufi, Undergraduate at Queen Mary University of London

The globe focussed on Arabia
We often hear of famous computer scientists who have helped changed the way we think of computers today. People such as Blaise Pascal, John Louis Von Neumann and most famously, Charles Babbage also known as "the Father of Computing". However, "Every father is the son of a Father" so although the works of people like Charles Babbage were modern in their time and no doubt did shape the future of modern technology, their work built on that of others. So the question arises, who was the grandfather of computing? One of the fundamental aspects of computing is maths. After all, the first ever computer was built to calculate simple maths.
It was under the Islamic Khoulafah (plural for Khalifah [Caliphates]) such as the Omayyads and Al-Ma'mun that the mathematical sciences really advanced and new discoveries were made. Even the Europeans would flock to the East to benefit from the immense contributions made by the Islamic scholars. It was during this time that the Muslims in the Arabian peninsular began to interpret the already existing mathematical sciences from sources like the Greeks and further advanced it beyond the comprehension of any other civilization of the time.
Europeans would flock to the East to benefit from the immense contributions made by the Islamic scholars
Algebra was one of the most focussed-on subjects. One of the greatest people to contribute to and advance Algebra was Al-Khwarizmi. On becoming a member of Dar Al-Hikmah (the House of Knowledge) in Baghdad in the 800s he made immense advancements to Mathematics, astronomy, astrology, and more. In fact the word Algebra came from the Arabic word Al-Jabr from his book 'Al-Kitab al-mukhtasar fi hisab al-jabr wa'l-muqabalah' ('The Compendious Book on Calculation by Completion and Balancing'). Most algebra we use today for computing is taken from the ideas left in his priceless books. Furthermore, it was he who explained the use of the number zero. It was introduced to the world by previous Muslim scholars and scientists and "was used by the Arabs at least 250 years before it became known in the west". Moreover, "Khwarizmi's algebra is regarded as the foundation and cornerstone of the sciences. In a sense, Khwarizmi is more entitled to be called 'the father of algebra' than Diophantus because Khwarizmi is the first to teach algebra in an elementary form and for its own sake.".
Other great contributers to the mathematics we use both in general and in computer science were Al-Nasavi who authored 'Abnugna Fil Hissab Al-Kindi'. It explained the division of fractions and the extraction of square and cubic roots. Then we have Abul Kamil who improved the ideas of Al-Khwarizmi including the algebraic treatment of pentagons and decagons. Thabit bin Qurra handled geometry in his dissertation on astronomy and mathematics.
It was only centuries later that maths was introduced into Europe after the works of such scholars were translated into Latin and other languages surviving after it had perished in Arabic. The translations survived although much of their original work was not translated and was lost forever.
So what was it that made these people, to whom we owe so much, do great works? Well the answer is clear and simple. Whilst many of today's scientists conduct their work under the name of research, these people did so in the name of Islam.
So next time you sit in front of the computer, look at a table, graph or map, or do a little maths, remember these people. Then again, with their discoveries named after them (Algebra and Algorithm) that shouldn't be hard.
**Note that the actual invention of the number 0 is credited to Indian scholars. The Arab contribution is essentially to popularise it throughout the world and specifically to the West.
