Numbers

… Muslims devised modern numerals, numbers 1 to 9 we use today in English, based on the use of the zero. Number 1 for example, had one angle, 2 has two angles, 3 has three and so on. The invention of these numerals resolved the problems faced by the Latin numerals...

Elephant Clock

(1001 Inventions Book, Page 14-17)
Muslim Scholars brought many new inventions and also they improved or re-introduced old inventions like the Elephant clock which embraced many cultures as a scientific dedication of respect and understanding... The seven meters high clock uses Greek water raising technology, an Indian elephant, an Egyptian phoenix, Arabian figures, Persian carpet, and Chinese dragons, to celebrate the diversity of the world

Al-Qahwa - Coffee

Coffee was discovered by the Muslims sometimes around the 10th century. It was first used and cultivated in Yemen. Instead of eating the beans, the Yemenis boiled them creating the famous drink of “Al-Qahwa”. There is also consensus that the first users of coffee were the Sufis who used it as a stimulus to stay awake during late night Thikr (remembrance of God). Coffee spread to the rest of Muslims of Yemen and eventually to all the Muslim world through travellers, pilgrims and traders... (1001 Inventions Book, Page 12-13)

· 1.6 billions cups of coffee are drunk worldwide everyday… (http://www.muslimheritage.com/ )

· It was a Turk named Pasqua Rosee, a merchant in 1650 CE who first brought the coffee into UK (in Europe 1945) (http://www.muslimheritage.com/ )

· Coffee houses was an place of wisdom which scholars gathered to discuss and study ‘ilim’ (theology as well as science)

· Also today’s popular Coffee house trend like (from Lloyds Coffee House to) Starbucks, Caffe Nero etc. comes from the assimilation of this enlightenment

· The English word "coffee" first came into use in the early to mid 1600s, but early forms date back to the last decade of the 1500s. It comes from the Italian caffè and the French, Portuguese and Spanish café. These, in turn, were borrowed from the Ottoman Turkish kahveh, borrowed from the Arabic qahhwa. (http://en.wikipedia.org/)

· The origin of the Arabic qahwa (قهوة), is uncertain. It is either derived from the name of the Kaffa region in southern Ethiopia, where coffee was cultivated, or by a truncation of qahwat al-būnn, meaning "wine of the bean" in Arabic. (http://en.wikipedia.org/)

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" Published: 11 March 2006

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.

Traditional Islamic geometrical designs













Title: " Islamitische Geometrische Patronen Zelf Ontwerpen en Maken" author: Eric BrougISBN: 9054601345, published bij Bulaaq Publishers in Amsterdam, The Netherlands This book shows in a clear step-by-step approach how to make traditional Islamic geometrical designs. Traditional Islamic craftsmen weren't mathematicians, they had practical knowledge of geometry, their tools for making geometrical designs were a compass and a ruler. This book uses the same design principle. It demonstrates how Islamic craftsmen would draw a hexagon and a pentagon with only their tools of a compass and a ruler. The method used in this book is new and innovative; it makes it easy for enthusiasts of any age to learn how to make their own designs. The book contains twenty different geometrical designs, ranging from simple to complex. All designs are related to a location in the Islamic world where they can be found. For example, there are designs from:- the Great Mosque of Cordoba, Spain- the Mustansiriya Mosque in Baghdad, Iraq- the Esrefoglu Mosque in Beysehir, Turkey- the Sheikh Abd al-Samad Complex in Natanz, Iran- the tomb of Bibi Jawindi in Uch, Pakistan- the Umayyad Mosque in Damascus, Syria- the Tomb of Jalal al-Din Hussein in Uzgen, Kirgizstanthe book is accompanied with an interactive CD-Rom that contains all twenty designs presented as animations, printable gridpaper PDF's, printable colouring designs, interactive photographs and an extensive photogallery showing highlights of Islamic geometrical compositions.

COMMENT:There is ample evidence that Mathematicians actually instructed Artisans to develop complex patterns. Using Compass and ruler is limited to simple geometries (Prof. Salim Al-Hassani)

* Scientists uncover geometric genius
*Western thinkers 500 years behind

Medieval Islamic artists produced intricate decorations patterns using geometrical techniques that were not understood by western mathematicians until the 20th century, scientists have discovered.

The combinations of ornate stars and polygons that have adorned mosques and palaces since the 15th century were created using a set of just 5 template tiles, which could generate patterns with a kind of symmetry that eluded former mathematical description for another 500 hundred years.

The discovery, by Peter Lu, of Harvard University, published in the journal Science, suggests that the Islamic artisans who created these typical girih designs had an intuitive understanding of highly complex mathematical concepts, even if they had not worked out the underlying theory. “We cant’
say for sure what it means,” said Mr Lu, who is studying for a PHD in physics. “It could be proof of a major role of mathematics in medieval Islamic art or it could have been just a way for artisans to construct their art more easily.

“It would be incredible if it were all coincidence. At the very least, it shows us a culture that we often don’t credit enough was far more advanced than we fought”.

Girih designs feature arrays of tessellating polygons of multiple shapes, and are often overlaid with a zig-zag network of lines. It had been assumed that, straight-edge rulers and compasses were used to create them – an exceptionally difficult process as each shape must be precisely drawn.

From the 15th century, how ever, some of these designs are symmetrical in a way known today as “quasicrystalline”. Such forms have either five-fold or ten-fold rotational symmetry _meaning they can be rotated to either five or ten positions that look the same _ and their patterns can be infinitely extended without repetition. The principles behind quasicrystalline symmetry were calculated by the mathematician Roger Penrose in the 1970s, but it is now clear that Islamic artists were creating them more than 500 years earlier.

Mr Lu, who designs physics, experiments for the International Space Station, began wondering whether there were quasicrystalline forms in Islamic art after seeing decagonal artworks in Uzbekistan, which he visited after a trip to a space Facility in Turkmenistan.

On returning to Harvard, he started searching the university’s vast library of Islamic art for quasicrystalline designs. He found several, as well as architectural scrolls that contained the outlines of 5 polygon templates _ ten-sided decagon, a hexagon, a pentagon, a rhombus and a bow-tie shape _ that can be combined and overlaid to create such patterns.

There is no evidence that the template tiles were themselves attached to surfaces to create mosaics. Artists probably used holes in the templates to trace a design onto a surface, which would be made into a mosaic.
