Daily Dawn, Sci-Tech, 25-03-2006 (http://www.dawn.com/weekly/science/science3.htm) The following article may give those detractors something
to eat humbly who think Muslims had done nothing in the world science. -----------------------------------
How Muslim inventors changed the world
By Paul Vallely
From coffee to cheques and the three-course meal,
the Muslim world has given us many innovations that we in the West take
for granted. Here are 20 of their most influential innovations:
(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 Makkah 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 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 Book of Knowledge of Ingenious Mechanical Devices (1206) 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.
However, 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. The
architect of Henry V’s castle 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.
Muslim 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).
(16) Carpets were regarded as part of paradise by mediaeval 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. 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) Mediaeval 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. (Courtesy: The Independent)
