             In the modern world Islam is seen as many things, but rarely
     is it viewed as a source of inspiration and enlightenment.
     Though it is a force of enlightenment and it is not only verses of
     the Quran that testify to that fact, but also the great body of
     scholarship produced during the Middle Ages. While Europe was in the
     midst of darkness, it was the Muslims, spurred on by the light of
     their new Deen who picked up the torch of scholarship and
     science.  It was the Muslims who preserved the knowledge of
     antiquity, elaborated upon it, and finally, passed it on to Europe.

             Although every peoples earn what they do and pass on, it is
     important for us to learn about and appreciate the
     contributions of the Islamic civilization by the early Muslims.
     Colonialism, the institution of the Western educational model, along
     with Eurocentrism often portrays Islam as backwards, incompatible
     with science and technology and anti-educational.  Muslim school
     children never learn of their glorious past and often the only thing
     passed on to them is the inferiority complex of the generation before
     them.  From the past we can learn from our mistakes and use the
     analysis of  those great examples before us as role models to enrich
     us in the future.

             In the seventh century A.D., the prophet Muhammad (SAW) was
     sent to the people of Arabia.  Within a decade of his death
     the Muslims had conquered all of the Arabian peninsula. Within a
     century, Islam had spread from  Al-Andalus in Spain to the borders of
     China.  Islam unified science, theology, and philosophy.  Muslims were
     commanded to study, seek knowledge, and learn and benefit from
     others' experiences by Allah (SWT) in the holy Quran and by the
     prophet Muhammad (SAW) in the Sunnah. It was this that inspired the
     Muslims to great heights in sciences, medicine, mathematics,
     astronomy, chemistry, philosophy, art and architecture.

             Muslim scholars began obtaining Greek treatises and started
     their study and translation into Arabic a few centuries after
     the Hijrah (622 A.D.)  They critically analyzed, collated , corrected
     and supplemented substantially the Greek science and philosophy.
     After this period began what is known as the Golden Age
     of Islam, which lasted for over two centuries. It is here we find
     many of the great scientists of Islam who literally left behind
     hundreds and thousands of books on the various branches of science.

             Abu Ali al-Hussain Ibn Abdallah Ibn Sina, universally known
     as Avicinna (980-1037),  alone wrote 246 books, including
     Kitab-al Shifa (The Book of Healing) consisting of 20 volumes and Al-
     Qanun fit Tibb (The Canons of Medicine) . The Qanun was the chief
     guide for medical science in the West from the twelfth to the
     seventeenth century.  Dr. William Osler, who wrote The Evolution of
     Modern Science,  remarks "The Qanun has remained a medical Bible for
     a longer period than any other work".  Containing over
     a million words, it surveyed the entire medical knowledge available
     from ancient and Muslim sources, and including his own original
     contributions.

             Ibn Sina's  original contributions included such advances
     such as recognition of the contagious nature of phtisis and
     tuberculosis; distribution of diseases by water and soil and the
     interaction between psychology and health.  Also, the book described
     over 760 drugs and became the most authentic of its era.  Ibn Sina
     was also the first to describe meningitis and made rich contributions
     to anatomy, gynaecology and child health.

                     This interest in medicine went back to the time of
     the Prophet (SAW), who once said that there
     existed a cure for every disease.  With this spirit there were
     hospitals and clinics built all over the Muslim world, the earliest
     built in 707 by Caliph Walid ibn Abd a-Malik in Damascus.
     Muslims made many advances such as the idea of circulation of
     blood and quarantine and the foundation of the first apothecary shops
     and the earliest school of pharmacy.

             Hunayn ibn Ishaq, a philosopher and physician made advances
     in Medicine, Physics, Mathematics, Astronomy Veterinary
     Science, and Ophthalmology.  He was the head of the famous school of
     translators founded by Caliph Mamun at Baghdad and wrote the first
     systematic text book on opthamology.

             Abu Bakr Muhammad ibn Zakariya al-Razi (865-925 AD) , known
     as Rhazes, was one of the most prolific Muslim doctors and
     probably second only to Ibn Sina in his accomplishments.  He was born
     at Ray, Iran and became a student of Hunayn ibn Ishaq and later a
     student of Ali ibn Rabban. He wrote over 200 books, including Kitab
     al-Mansuri, ten volumes on Greek medicine, and  al-Hawi, an
     encyclopedia of medicine in 20 volumes.  In al-Hawi, he
     included each medical subject's information available from Greek and
     Arab sources and then added his own remarks based on his experience
     and views.  He classified substances as vegetable, animal or mineral
     while other alchemists divided them into "bodies", "souls" and
     "spirits".

             Al-Razi was first placed in charge of the first Royal
     Hospital at Ray, from where he soon moved to a similar
     position in Baghdad where he remained the head of its famous
     Muqtadari Hospital for a long time.  He found a treatment for kidney
     and bladder stones, and explained the nature of various infectious
     diseases. He also conducted research on smallpox and
     measles and was the first to introduce the use of alcohol for medical
     purposes.  A unique feature to his medical system was
     that he greatly favored cure through correct and regulated food
     intake.  This was combined with his emphasis on the influence of
     psychological factors on health.  He also tried proposed remedies
     first on animals in order to evaluate their effects and side
     effects.  He was also an expert surgeon and the first to use opium
     for anesthesia.

             Another great physician who soon followed was al-Razi was
     Abul Qasim al-Zahrawi (963-1013 AD) who is known as Albucasis
     to the West.  A famous surgeon in his time, at the court of Caliph
     al- Hakam II , students and patients flocked to him from the Muslim
     world and Europe.  He wrote the medical encyclopedia al-Tasrif li man
     ajaz an-il-talif, which contained 30 sections of surgical knowledge
     and illustrations of 200 surgical instruments, most of which he
     designed himself. The Encyclopedia was not only a standard for
     physicians, but even five centuries later it was being used as the
     standard textbook on surgery in universities in Europe.
     He also performed many delicate operations such as Cesareans and was
     also the first to use silk thread for stitching wounds.

             Al-Idrisi was born in Cordova, Spain in 1099.  His major
     contribution was in medicinal plants which he described in
     many books, such as Kitab al-Jami-li-Sifat Ashtat al-Nabatat.   He
     collected plans and data not reported earlier and added this to the
     subject of botany.  From him a large number of new drugs from plants
     with their evaluations became available to medical practitioners.
     Al-Idrisi also made original contributions to topography, as related
     to economics, physical factors and cultural aspects.  He wrote
     geographical encyclopedias, the largest called Rawd-Unnas wa Nuzhalat
     Nafs (Pleasure of Men and Delight of Souls).  Al-Idrisi
     also wrote on the subjects of fauna, zoology and threapeutical
     aspects.  His work was soon translated into Latin and his books on
     geography especially remained popular in the east and west for
     several centuries.

             Working in the field of botany as well was abu Muhammad Ibn
     al-Baitar, also from Spain.  He was one of the greatest
     scientists of Muslim Spain and one of the greatest botanists and
     pharmacists of the Middle Ages.  He went on many traveling
     expeditions to collect plants as far as Africa and Asia Minor. He
     wrote Kitab al-Jami al-Adiwaya al-Mufrada, one of the greatest
     botanical compilations dealing with medicinal plants in Arabic  The
     encyclopedia was made of over 1,400 items, many of which were not
     known before.  The book referred to the works of 150 authors, mostly
     Arabic and quoted about 20 early Greek scientists.  It was translated
     into Latin and published as late as 1758.

             Ibn al-Baitars works were characterized by observation,
     analysis and classification and exerted a profound influence
     on Eastern as well as Western botany and medicine.  Even though many
     of his works were translated and published late in the western
     languages, many earlier scientists had studied various parts of the
     book and made several references to it.

             At the same time as these advances in medicine were being
     made, the Muslims produced some of the most outstanding
     Mathematicians.  Muhammad ibn Musa al-Khwarizmi, born in 780 A.D.,
     was the founder of modern Algebra.  He developed sine, cosine and
     trigonometrical tables, which were later translated to the West.  His
     book on algebra Hisab al-Jabr waal-Muqabalah (The Calculation of
     Integration and Equation) was used until the 16th century as the
     principal textbook of European universities.  In it he
     writes that given an equation, collecting the unknowns in one side of
     the equation is called al-Jabr and collecting the knowns in the other
     side of the equation is called al- Mukabalah.  He also described six
     basic types of equations:  nx=m , x^2=nx , x^2=m , m+x^2 =nx,  m+nx
     +x^2 and x^2=m+nx.  He also solved the particular equation
     x^2+21=10x using geometrical arguments.

             Al-Khawarizmi also helped introduce Arabic numerals, the
     decimal position system, and the concept of zero.  Algebra
     and Algorithm are in fact corruption's of his work and name.
     Interestingly, this first every book on algebra included many
     examples from the Islamic inheritance laws and how they could be
     solved using algebra.  Under al-Mamun the caliph of the time, he with
     some others were the first to map the globe.

             In the field of Algebra the Muslims continued with Thabit Ibn
     Qurra's more general equations solved by geometrical
     arguments.  In 901, Abu Kamil, called "the Egyptian calculator", did
     some work on algebra in which he established rules for manipulating
     algebraic expressions.  He also proved various laws such as
     ax*bx-abx^2, a(bx)=(ab)x and (10-x)(10-x)=100+x^2-20x (Mirza, p124).
     Around 1000, Abu Bakr Al-Karaji, in his book  The Marvelous discussed
     higher order equations such as fourth and fifth order equations,
     combing geometry and arithmetic.  Al-Samawal
     established the power law x^nx^n=x^(m+n) in 1180 in his work The
     Shining which is just one of his 85 books.  He also worked on
     performing multiplication of algebraic expressions involving terms
     with different powers and division of polynomials. Abu
     Yunus proved the famous identity cos(a)cos(b)={cos(a+b)+cos(a-b)}/2
     and used spherical trigonometry to set formulas to computer prayer
     times.  Al-Biruni also used spherical trigonometry to find the
     direction of Mecca or any other city on the globe.

             Another outstanding mathematician was Ghiyath al-Din al
     Kashani of the late fourteenth century.  He worked on the
     theory of numbers and techniques of computations. In 1424, he
     computed a value of 2pi to sixteen decimal digits of accuracy using
     an approximation of the circle by 805306368 side polygon.  One of his
     most important works was Miftah elHussab or The Calculators' Key, in
     it he described an algorithm for finding the fifth root of any
     number.  The book was used in Persian schools until the seventeenth
     century.  Later in his life he moved to Samarkand at the request of
     the then ruler to help direct a new scientific school and observatory
     and conduct research with other scholars of the time.  Kashani also
     wrote on how to approximate sin(1) by solving a cubic equation
     accurately.

             Umar Khayyam known to the west as only a poet actually also
     was an excellent mathematician.  He criticized Euclid's
     theorems, evolved a methodology for the solution of third degree
     equations, and did research in the field of binomials and their
     coefficients.

             Abu Wafa Muhammad  al-Buzanji was born in Buzjan, Nishapur in
     940 A. D.  He became a great mathematician and astronomer at
     Baghdad and died in 997 A.D.  Al-Buzanji's main contribution lies in
     several branches of mathematics, in geometry and trigonometry
     especially.  In geometry he contributed to a solution of geometrical
     problems with opening of the compass, construction of a square
     equivalent to other squares, regular polyhedra, construction of
     regular hectagon taking for its side of the equilateral triangle
     inscribed in the same circle, constructions of parabola by points and
     geometrical solution of the equations x4=a and x4+ax3=b.

             Al-Buzanji's contribution to the development of trigonometry
     was also extensive.  He was the first to show the generality
     of the sine theorem relative to spherical triangles.  He developed a
     new method of constructing sine tables, the value of sin 30` being
     correct to the eight decimal place.  He also developed relations for
     sine(a+b) and the formula: 2 sin2 (a/2) = 1 -cos a  and sin a = 2 sin
     (a/2) cos (a/2).  In addition he studied tangent and
     calculated tables for them.  He introduced the secant and cosecant
     for the first time.  He wrote a large number of books on mathematics
     and other subjects, most of which have been lost or exist in modified
     forms.  He also wrote rich commentaries on Euclid, Diophanatos and
     al-Khwarizmi.  A sizable part of today's trigonometry can be traced
     back to him.

             Abu Abdullah al-Battani (862-929 A.D.) was a son of a
     scientist and also a famous astronomer, mathematician and
     astrologer.  He is often considered one of the greatest astronomists
     of Islam.  His career of 42 years included a number of important
     discoveries, including the accurate determination of the solar year
     as 365 days, 5 hours, 46 minutes, and 24 seconds, which is very close
     to modern estimates.  He also determined with accuracy
     the obliquity of the ecliptic, the length of the seasons and the true
     and mean orbit of the sun.  He proved that in contrast to Ptolemy,
     the variation of the apparent angular diameter of the sun and the
     possibility of annular eclipses.  His observations of lunar and solar
     eclipses were used by Dunthorne in 1749 to determine the secular
     acceleration of motion of the moon.

             In mathematics, al-Battani was the first to replace the use
     of Greekchords by sines and the first to develop the concept
     of cotangent and furnished their table in degrees.  He wrote a number
     of books on astronomy and trigonometry.  His most famous book was his
     astronomical treatise with tables which was translated into Latin in
     the 12th century, called De Sceinta Stellerum De numeris Stellerum et
     Motibus.  This was extremely influential in Europe until the
     Renaissance, with translations available in several languages.
     His original discoveries in both astronomy and
     trigonometry were of great consequence in the development of those
     sciences.

             In the related field of  Physics, Abu al-Fath Abd al-Rahman
     al-Khazini studied mechanics and hydrostats and wrote books
     on physics and astronomy.  Al-Biruni, a geographer, chronologist,
     mathematician, astronomer, was also a physicist.  His Elements of
     Astrology remained a textbook for centuries and he also wrote on
     specific gravity, and developed formulas to determine absolute and
     specific weights of all objects.

             Abu al-Hassan al Haitham (965-1039 AD)  was one of the most
     eminent physicists, whose contribution to optics and the
     scientific method were great.  Originally from Basra, he went to
     Egypt where he was asked to find ways of controlling the flood of the
     Nile.  Being unsuccessful in this, he feigned madness until the death
     of Caliph al-Hakim.  He also traveled to Spain and during this time
     also had time for his scientific pursuits.  He wrote treatises such
     as Kital al-Manzir on light, worked with mirrors and lenses,
     reflection, refraction, and magnifying and burning glasses.
     He discussed the propagation of light and colors, optic
     illusions and opposed the view of Euclid and Ptolemy that the eye
     sent out visual rays.  From studying motion, he discovered the
     principle of inertia.

             He contradicted Ptolemy's and Euclid's theory of vision that
             objects are seen by rays of light emanating from the eyes.
     According to Haitham,  the rays originated in the object of vision
     and not in the eye.  Through this kind of extensive research on
     optics, he has been considered the father of modern Optics.  Roger
     Bacon and all medieval Western writers on optics based their work
     largely on his Opticae Thesaurus and it even influenced Leonardo da
     Vinci, Johann Kepler and Newton..  Haitham also studied
     the phenomena of sunrise and sunset and explained rainbows through
     the principle of reflection.  He was known for the
     earliest use of the camera obscura as well.

             Al-Kindi (d. 873 AD) considered the first philosopher of the
     Arabs, also contributed to Physics , Optics,  reflection of
     light, specific weights, tides and metallurgy.

             Muslims also made discoveries in Chemistry by discovering
     many new substances such as potash, nitrate of silver,
     corrosive sublimate and nitrate and sulfuric acid as well as
     improving methods for evaporation, filtration, sublimation,
     calcination, melting, distillation, and crystallization.
     Jabir, otherwise known as the father of Arab alchemy
     contributed in the fields of Pharmacology and Toxicology.

             Al-Asma'i (740-882 AD) was a philologist who contributed to
     Zoology, Botany and Animal Husbandry. Other
     Muslim botanists described plants in detail, medicinal herbs,
     physiology of plants and wrote books on horses, camels, sheep, birds,
     the history of bees and locusts, the effect of climate on the
     behavior of animals and men. Also working on the subject
     of Botany, Suri al- Dimashqi researched plants around Damascus and
     Lebanon at different stages of growth.

             In the field of geography, Ibn Majid invented the compass.
     The Muslims traversed the Indian, Atlantic and
     Pacific Ocean as well as sailing around the African continent, in
     their trading with India, Iran and Greece. They wrote such books as
     Akhbar al-Hind (Reports on India), Akhbar al-Sin (Reports on China)
     and Ajib al-Hind (Curiosities of India).  Sulaiman
     Al-Makri wrote of his travels in Al-budat and other books.  Abu
     al-Hasan al-Masudi, a historian and scientist, traveled the world
     journeying from Persia, Central Asia, India, the Near East,
     Madagascar and the China Sea.  He wrote his encyclopedic volume on
     his travels which included history, cosmology and geography.

             Al-Biruni was the first known writer to identify certain
     geological facts, such as the formation of sedimentary rocks
     and the great geological changes that happened in the past.  He was
     also the founder of geodesy and wrote and improved upon the methods
     of measuring longitudes, latitudes, heights of mountains and the
     diameter of the earth. He also wrote on biological evolution.

             Of the many scientists in the field of astronomy, Al-Sufi
     helped build a famous observatory under the Buwayh sultan
     Sharaf-al-Dawlah.  He prepared charts of the heavens with magnitudes
     and was the first to mark the nebula of Andromeda in his atlas.
     Al-Zarqali from al-Andalus invented the astrolabe and
     measured the rate of motion. He also constructed
     astronomical instruments and built a water clock.

             Jabir ibn Aflah was a Spanish Arab who criticized Ptolemy's
     heliocentric theory of planetary motion. He designed the
     first portable celestial sphere to explain and measure the movements
     of celestial objects and led the way for spherical trigonometry.
     Al-Bitruji developed a new theory of stellar movements.
     Names of many constellations, words like zenith and
     nadir and even names of craters of the moon all go back to the works
     of Muslim scholars of this time.

             We can see that these Islamic sciences had a great impact
     upon both the Western world and also the two major
     civilizations east of the Islamic world, India and China.  Without
     the Islamic scientists and their work, the development of science in
     these civilizations would have been different.  Between
     the eleventh and thirteenth centuries the major works of Islamic
     scientists were translated into Latin in Spain, Sicily and Italy.
     Muslim scientists like Ibn Sina and al-Razi became household names in
     the West.  Islamic medicine led the way for European medicine.

             In the field of mathematics the works of al-Khwarazmi and
     others were taught in the Western universities for centuries.
     Astronomical tables written in the West were based
     upon the work of Muslims before them.  Treatises on algebra that were
     written were mostly based on the work of Khayyam.  Works in chemistry
     written in Latin used an extensive Arabic vocabulary because there
     was no Latin vocabulary in this field.

             Many of these scientists were also great philosophers, such
     as Ibn Sina and al-Razi. Ibn Sina initially began studying
     logic, from there he studied physics and metaphysics and was the
     first to develop a complete philosophical system in Arabic.
     Ibn Sina's philosophical encyclopedia Kitab al- Shifa was a
     monumental work, embodying a vast field of knowledge from philosophy
     to science.  He classified the entire field as follows: theoretical
     knowledge; physics, mathematics, and metaphysics; ethics, economics
     and politics.  His philosophy synthesized Aristotelian tradition,
     Neoplatonic influences and Muslim theology.  Besides al-Shifa his
     well-known treatises in philosophy are al-Najat and Isharat.

             Al-Razi's contribution as a philosopher was also well known.
     The basic elements in his philosophical system were the
     Creator, the spirit, matter, space and time.  He discussed their
     characteristics in detail and his concepts of space and time as
     constituting a continuum.  His philosophical views were, however,
     criticized by a number of other Muslim scholars of the era.

             During the time of Harun al-Rashid (786-809) the Muslims
     built a library which contained both originals and
     translations of almost any then known scientific work in Sanskrit,
     Persian and Greek. His son, Caliph al-Mamun  continued the tradition
     of philosophy and science and established in Baghdad  his Bayt
     al-Hikmah (House of Wisdom), a library and academy.
     Here the objective was to collect all scientific works, translate
     them into Arabic and copy and bind them into books to preserve them.
     No doubt much of the knowledge of the Greeks and others was preserved
     in this way.

             The greatest figure in Islamic philosophy is held to be Imam
     al-Ghazali, who was a jurist, theologian, philosopher and
     mystic.  Born in 1058 in Khorasan, he came to have a high standard of
     scholarship in religion and philosophy a
