Basically, physics was divided into two branches, mechanics and optics. This article only touches innovations in mechanics as it was during the Bani Saljuq rule that many innovations took place in the area of mechanics in various aspects, including weight measurement and specific gravity of a substance. The most prominent figure of that time was al- Khazini. Key words: Banu Saljuq Era, Abbasid era, mechanics and optics Cite this Article: Roziah Sidik @ Mat Sidek and Wan Hamdi Wan Sulaiman.

INTRODUCTION WHAT IS INNOVATION? The word innovation originates from the Latin word which means to renew or innovare which means to renew or amend. It is a topic discussed in various disciplines including economics, commerce, engineering as well as sociology. Thus its definition varies and may probably differ according to the relevant discipline. Ioan Lala Popa, Gheorghe Preda and Monica Boldea (n.d.) listed various definitions of innovation put forward by many scholars. Joseph Schumpeter, for example, in giving his definition of innovation, made a long list including introducing a new product or modifications brought to an existing product; a new process of innovation in an industry; the discovery of a new market; developing new sources of supply with raw materials; other changes in the organization. Peter Druker referred to innovation as one of the two basic functions of an organization. And Howard and Sheth explained innovation as any new element brought to the buyer, whether or not new to the organization. Other than that, Mohr (1976) defined innovation as the degree to which specific new changes are implemented in an organization. Damanpour and Evan explained it as a broad utility concept defined in various ways to reflect a specific requirement and characteristic of a particular study. http://iaeme.com/Home/journal/IJCIET 843 [email protected] Roziah Sidik @ Mat Sidek and Wan Hamdi Wan Sulaiman According to Kenneth Simmonds, innovations are new ideas that consist of: new products and services, new use of existing products, new markets for existing products or new marketing methods. Damanpour (1991) views innovation as development and adoption of new ideas by a firm, while Davenport defined it as completing a task development in a radically new way. For Evans, innovation is the ability to discover new relationships, of seeing things from new perspectives and to form new combinations from existing concepts. According to Covin şi Slevin, Lumpkin and Dess and Knox, innovation can be defined as a process that provides added value and a degree of novelty to the organization, suppliers and customers, developing new procedures, solutions, products and services and new ways of marketing. And the Australian Business Council defines innovation as adoption of new or significantly improved elements to create added value to the organization directly or indirectly for its customers. In Henderson’s view (1990), innovation refers to implementation of innovative ideas. Nohria and Gulati explained it as any policy, structure, method, process, product or market opportunity that the manager of a working business unit should perceive as new. For Rogers, innovation involves both knowledge creation and diffusion of existing knowledge. In The New Oxford Dictionary of English, innovation is defined as making changes to something established by introducing something new. The European Commission Green defines it as successful production, assimilation and exploitation of novelty in the economic or social environment. In addition, Boer and During defined it as creating a new association (combination) product-market-technology-organization. According to Kamus Dewan (2007), innovation refers to something new introduced such as a method, system, custom and so on. Ahmad Shukri and Amran (2005) associated innovation with design considered as a new idea or concept generated through the process of research and development. However, this design becomes an innovation only when it is a product or process which can be commercialized. Although various definitions have been submitted by scholars, in the context of this research, focus is on new refinements and inventions in the field of science and technology through scholarly efforts during Banu Saljuq rule. This article focuses specifically on innovations in the field of physics under Banu Saljuq. 2. ‘ABBASID BANU SALJUK ERA Throughout a period of 508 years, the Abbasid administration changed rulers three times, that is, Banu Abbas, Banu Buwayh and Banu Saljuq. Banu Abbas rule began in the year 750CE and lasted until 847CE. During this time, the caliph had absolute authority in administering affairs of the empire.. The Banu Buwayh era began in the year 945CE lasting until 1055CE. During this time, the Banu Abbas caliphate was still present but its power was limited to only religious affairs, while Banu Buwayh held political powers. The Banu Saljuq era lasted from the year 1038CE to 1258CE (see map below). Even in this era, the Banu Abbas caliphate still existed but its powers was also limited to religious affairs, while Banu Saljuq held political powers and controlled the military. http://iaeme.com/Home/journal/IJCIET 844 [email protected] Innovations in Physics of Banu Saljuq Era Source: http://www.mideastweb.org/middle-East- Encylopedia/seljuk_map [23 July 2013] The emergence of the Banu Saljuq in mid-11th century CE carved a new Islamic history in the political and social arena because it succeeded in forming a third Islamic nation after the Arabs and Persians (Saunders 1965: 287). Among the special characteristics of the Banu Saljuq was their holding fast to Islamic teachings and their strong inclination to Sunni denomination (ahl Sunnah wa al-Jama’ah). During that time, the Muslim community achieved high progress in science and technology. In addition, various arts emerged thoughout Banu Saljuq rule (Ensiklopedia Dunia. 2005 19: 71). 3. INNOVATIONS IN FIELD OF PHYSICS The word physics originates from the Greek word Physis which means natural. In the Islamic civilization, there was no physics discipline as we understand it today. Physics then was understood as a natural philosophy which covers life sciences, earth sciences, and physics itself. Physics concepts such as sound, light, vacuum, energy, motion, atom, force, gravity, momentum, law of light refraction, image formation by the lens, laws of mechanics, earthquake, mechanics, hydrostatistics and parabolic motion were studied by scientists in the Islamic civilization since long ago. Among the scientists or physicists in the Islamic civilization were al-Farabi, Ibn Sina, Abu al-Barakah al-Baghdadi, Nasir al-Din al-Tusi, Ibn Bajah, Ibn Rushd, Ibn ‘Arabi, Banu Musa Ibn Shakir, Hassan al-Biruni, al-Jaldaki, al- Khazini, al-Biruni, al-Kindi, Ibn al-Haytham, Ibn Yunus and Ibn Razzaz. Basically, physics was divided into two branches, mechanic and optics. However discussion in this study touches only on innovations in mechanics as during Banu Saljuq rule, innovations were mainly in the area of mechanics. http://iaeme.com/Home/journal/IJCIET 845 [email protected] Roziah Sidik @ Mat Sidek and Wan Hamdi Wan Sulaiman 4. INNOVATIONS IN MECHANICS During Banu Saljuq rule, various innovations in mechanics were introduced. This includes weight measurement and specific gravity of substance. In discussing innovations in physics, specifically weight measurement, we cannot leave out the name of a great figure such as al- Khazini. He was known for introducing systematic weight measurement. In determining weights, he referred much to the work of Archimedes entitled The Weight of the Crown (Rosenthal 1994), besides drawing from the works of past Muslim figures such as al-Nayrizi and al-Biruni in developing the balance as an instrument of measuring weight with accuracy. He realized the role of heat as affecting the density of an object. The word eureka ( I found it!), a historically reputed exclamation of Archimedes when he discovered or solved something, was frequently mentioned by al-Khazini to himself when he applied the Archimedes principle in developing a formula to determine weight. Initially, scholars of the Islamic civilization studied mechanics and hydrostatics. Studies on mechanics were done by Banu Musa, while al-Biruni and ‘Umar al-Khayyam studied hydrostatics. According to Nasr (1984), during the ‘Abbasid Banu Saljuq rule, al-Khazini introduced innovations by combining studies on menchanics and hydrostatics.. He gave full attention to the centre of gravity concept used in balancing. Al-Khazini formulated a theory to apply to gold and silver in alloy, mixture of two metals. If X= weight of silver in alloy ; A= absolute weight of alloy ; S= gravity of alloy; d1= gravity of gold ; and d2= gravity of silver (Nasr 1976: 143), then the formula is as follows: I/d1– I/s X=A I/d1– I/d2 The above formula shows that al-Khazini had devised a new element to determine weight. Such a formula in the 12th Century CE was an innovation by al-Khazini, specifically in weight measurement. By this one theory, he succeeded in producing a weighing instrument as follows: Source: http:// www.republika.co.id [23 July 2013] http://iaeme.com/Home/journal/IJCIET 846 [email protected] Innovations in Physics of Banu Saljuq Era Source: Hill, Donald R.

  • The Correct Qibla
    The Correct Qibla S. Kamal Abdali P.O. Box 65207 Washington, D.C. 20035 [email protected] (Last Revised 1997/9/17)y 1 Introduction A book[21] published recently by Nachef and Kadi argues that for North America the qibla (i.e., the direction of Mecca) is to the southeast. As proof of this claim, they quote from a number of classical Islamic jurispru- dents. In further support of their view, they append testimonials from several living Muslim religious scholars as well as from several Canadian and US scientists. The consulted scientists—mainly geographers—suggest that the qibla should be identified with the rhumb line to Mecca, which is in the southeastern quadrant for most of North America. The qibla adopted by Nachef and Kadi (referred to as N&K in the sequel) is one of the eight directions N, NE, E, SE, S, SW, W, and NW, depending on whether the place whose qibla is desired is situated relatively east or west and north or south of Mecca; this direction is not the same as the rhumb line from the place to Mecca, but the two directions lie in the same quadrant. In their preliminary remarks, N&K state that North American Muslim communities used the southeast direction for the qibla without exception until the publication of a book[1] about 20 years ago. N&K imply that the use of the great circle for computing the qibla, which generally results in a direction in the north- eastern quadrant for North America, is a new idea, somehow original with that book.

  • The History of Arabic Sciences: a Selected Bibliography
    THE HISTORY OF ARABIC SCIENCES: A SELECTED BIBLIOGRAPHY Mohamed ABATTOUY Fez University Max Planck Institut für Wissenschaftsgeschichte, Berlin A first version of this bibliography was presented to the Group Frühe Neuzeit (Max Planck Institute for History of Science, Berlin) in April 1996. I revised and expanded it during a stay of research in MPIWG during the summer 1996 and in Fez (november 1996). During the Workshop Experience and Knowledge Structures in Arabic and Latin Sciences, held in the Max Planck Institute for the History of Science in Berlin on December 16-17, 1996, a limited number of copies of the present Bibliography was already distributed. Finally, I express my gratitude to Paul Weinig (Berlin) for valuable advice and for proofreading. PREFACE The principal sources for the history of Arabic and Islamic sciences are of course original works written mainly in Arabic between the VIIIth and the XVIth centuries, for the most part. A great part of this scientific material is still in original manuscripts, but many texts had been edited since the XIXth century, and in many cases translated to European languages. In the case of sciences as astronomy and mechanics, instruments and mechanical devices still extant and preserved in museums throughout the world bring important informations. A total of several thousands of mathematical, astronomical, physical, alchemical, biologico-medical manuscripts survived. They are written mainly in Arabic, but some are in Persian and Turkish. The main libraries in which they are preserved are those in the Arabic World: Cairo, Damascus, Tunis, Algiers, Rabat ... as well as in private collections. Beside this material in the Arabic countries, the Deutsche Staatsbibliothek in Berlin, the Biblioteca del Escorial near Madrid, the British Museum and the Bodleian Library in England, the Bibliothèque Nationale in Paris, the Süleymaniye and Topkapi Libraries in Istanbul, the National Libraries in Iran, India, Pakistan..

    History of Islamic Science George Sarton‟s Tribute to Muslim Scientists in the “Introduction to the History of Science,” ”It will suffice here to evoke a few glorious names without contemporary equivalents in the West: Jabir ibn Haiyan, al-Kindi, al-Khwarizmi, al-Fargani, Al-Razi, Thabit ibn Qurra, al-Battani, Hunain ibn Ishaq, al-Farabi, Ibrahim ibn Sinan, al-Masudi, al-Tabari, Abul Wafa, ‘Ali ibn Abbas, Abul Qasim, Ibn al-Jazzar, al-Biruni, Ibn Sina, Ibn Yunus, al-Kashi, Ibn al-Haitham, ‘Ali Ibn ‘Isa al- Ghazali, al-zarqab,Omar Khayyam. A magnificent array of names which it would not be difficult to extend. If anyone tells you that the Middle Ages were scientifically sterile, just quote these men to him, all of whom flourished within a short period, 750 to 1100 A.D.” Preface On 8 June, A.D. 632, the Prophet Mohammed (Peace and Prayers be upon Him) died, having accomplished the marvelous task of uniting the tribes of Arabia into a homogeneous and powerful nation. In the interval, Persia, Asia Minor, Syria, Palestine, Egypt, the whole North Africa, Gibraltar and Spain had been submitted to the Islamic State, and a new civilization had been established. The Arabs quickly assimilated the culture and knowledge of the peoples they ruled, while the latter in turn - Persians, Syrians, Copts, Berbers, and others - adopted the Arabic language. The nationality of the Muslim thus became submerged, and the term Arab acquired a linguistic sense rather than a strictly ethnological one. As soon as Islamic state had been established, the Arabs began to encourage learning of all kinds.

Al-Battani (d 929) known to the Latins as Albategni or Albatenius was the author of the Sabian tables (al-Zij al-Sabi), a work which had great impact on his successors, Muslim and Christian, in equal measure.1 His improved tables of the sun and the moon comprise his discovery that the direction of the sun's eccentric as recorded by Ptolemy was changing. This, in modern astronomy, means the earth moving in varying ellipse.2 He also worked on the timing of the new moons, the length of the solar and sideral year, the prediction of eclipses, and the phenomenon of parallax, carrying us `to the verge of relativity and the space age,' Wickens asserts.3 Al-Battani also popularised, if not discovered, the first notions of trigonometrical ratios as we use them today.4 During the same period, Yahya Ibn Abi Mansour had completely revised the Zij of Almagest after meticulous observations and tests producing the famous Al-Zij al Mumtahan (the validated Zij).

    6. Mathematics of Asian and Arabic civilizations — I I (Burton , 5.3, 5.5, 6.1 ) Due to the length of this unit , it has been split into two parts . Arabic /Islamic mathematics We have already mentioned that the term “Greek mathematics ” refers to a fairly wide geographic area and contributions of mathematicians of many nationalities . The same can be said about the mathematics associated to Arabic and Islamic cultures which flourished during the period from about 800 to 1500 , but the geographic area , the diversity of nationalities , and even the diversity of religions was much greater than in Greek mathematics . The geographic range included the entire Islamic world at the time, from Spain on the west to Uzbekistan on the east , many of the major figures had non – Arabic ethnic roots (for example , as elsewhere in Islamic culture , Persian contributions were very extensive) , and the role of Jewish scholars , largely in Spain , is particularly apparent (similar levels of participation and acceptance did not occur in mainstream European mathematics until the 19 th century) . When using phrases like “Arabic mathematics ” or “Islamic mathematics ” it is important to remember the geographic , ethnic and religious diversity of those who worked within this framework . In analogy with Greek mathematics , an important unifying factor is that Arabic was the language for most of the written output . Some Iranian bloggers have objected to terms like “Arabic mathematics ” or “Arabic science ” because they do not indicate the extremely important role of Persian scholars , and such complaints are perfectly understandable . Unfortunately , there is no simple way to describe this body of scientists that recognizes both its ethnic and religious diversity but fits easily into less than half of a single line , and in these notes we have chosen a frequently employed “abuse of language ” (with the preceding stipulation !) for the sake of conciseness .
