115-485: A blackboard or a chalkboard is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate , known, when used for this purpose, as chalk . Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone. A blackboard can simply be a board painted with a dark matte paint (usually black, occasionally dark green). Matte black plastic sign material (known as closed-cell PVC foamboard )
230-488: A diary or journal). The global spread of digital communication systems such as e-mail and social media has made writing an increasingly important feature of daily life, where these systems mix with older technologies like paper, pencils, whiteboards, printers, and copiers. Substantial amounts of everyday writing characterize most workplaces in developed countries . In many occupations (e.g. law, accounting , software design , human resources ), written documentation
345-412: A hydrostatic balance to determine the density and purity of metals and precious stones. He classified gems by what he considered their primary physical properties, such as specific gravity and hardness , rather than the common practice of the time of classifying them by colour. Biruni's main essay on political history, Kitāb al-musāmara fī aḵbār Ḵᵛārazm (" Book of nightly conversation concerning
460-778: A complex interaction among available tools, intentions, cultural customs, cognitive routines, genres, tacit and explicit knowledge, and the constraints and limitations of the writing system(s) deployed. Inscriptions have been made with fingers , styluses , quills , ink brushes , pencils , pens , and many styles of lithography ; surfaces used for these inscriptions include stone tablets , clay tablets , bamboo slats, papyrus , wax tablets , vellum , parchment , paper , copperplate , slate , porcelain , and other enameled surfaces . The Incas used knotted cords known as quipu (or khipu) for keeping records. The typewriter and subsequently various digital word processors have recently become widespread writing tools, and studies have compared
575-467: A cubit is not clear; with an 18-inch cubit his estimate would be 3,600 miles, whereas with a 22-inch cubit his estimate would be 4,200 miles. One significant problem with this approach is that Al-Biruni was not aware of atmospheric refraction and made no allowance for it. He used a dip angle of 34 arc minutes in his calculations, but refraction can typically alter the measured dip angle by about 1/6, making his calculation only accurate to within about 20% of
690-597: A given group of people, learnt their language and studied their primary texts, presenting his findings with objectivity and neutrality using cross-cultural comparisons. Akhbar S. Ahmed concluded that Al-Biruni can be considered as the first anthropologist, others, however, have argued that he can hardly be considered an anthropologist in the conventional sense. Biruni's fame as an Indologist rests primarily on two texts. Biruni wrote an encyclopedic work on India called Taḥqīq mā li-l-Hind min maqūlah maqbūlah fī al-ʿaql aw mardhūlah (variously translated as Verifying All That
805-606: A means of encoding language such that it can be read by others across time and space. While not all languages use a writing system, those that do can complement and extend the capacities of spoken language by creating durable forms of language that can be transmitted across space (e.g. written correspondence ) and stored over time (e.g. libraries or other public records). Writing can also have knowledge-transforming effects, since it allows humans to externalize their thinking in forms that are easier to reflect on, elaborate on, reconsider, and revise. Any instance of writing involves
920-620: A more dependable method for creating permanent records of transactions. On the other hand, writing in both ancient Egypt and Mesoamerica may have evolved through the political necessity to manage the calendar for recording historical and environmental events. Further innovations included more uniform, predictable, and widely dispersed legal systems, the distribution of accessible versions of sacred texts , and furthering practices of scientific inquiry and knowledge management , all of which were largely reliant on portable and easily reproducible forms of inscribed language. The history of writing
1035-455: A mountainous Egyptian mining site known as Serabit el-Khadem. This site was also home to a temple of Hathor, the "Mistress of turquoise". A later, two line inscription has also been found at Wadi el-Hol in Central Egypt. Based on hieroglyphic prototypes, but also including entirely new symbols, each sign apparently stood for a consonant rather than a word: the basis of an alphabetic system. It
1150-467: A refutation of astrology, in contradistinction to the legitimate science of astronomy, for which he expresses wholehearted support. Some suggest that his reasons for refuting astrology relate to the methods used by astrologers being based upon pseudoscience rather than empiricism and also to a conflict between the views of the astrologers and those of the orthodox theologians of Sunni Islam . He wrote an extensive commentary on Indian astronomy in
1265-416: A rich cultural context. He expressed his objectives with simple eloquence: He also translated the yoga sutras of Indian sage Patanjali with the title Tarjamat ketāb Bātanjalī fi’l-ḵalāṣ men al-ertebāk : I shall not produce the arguments of our antagonists in order to refute such of them, as I believe to be in the wrong. My book is nothing but a simple historic record of facts. I shall place before

#17328548679461380-555: A scientific but also a religious dimension: in Islam worship and prayer require a knowledge of the precise directions of sacred locations, which can be determined accurately only through the use of astronomical data. In carrying out his research, al-Biruni used a variety of different techniques dependent upon the particular field of study involved. His major work on astrology is primarily an astronomical and mathematical text; he states: "I have begun with Geometry and proceeded to Arithmetic and
1495-536: A semantic (meaning) element called a radical with an existing character to indicate the pronunciation, called a phonetic . However, such phonetic elements complement the logographic elements, rather than vice versa. The main logographic system in use today is Chinese characters , used with some modification for the various languages or dialects of China , Japan , and sometimes in Korean , although in South and North Korea ,
1610-565: A sound that is well known for being extremely irritating to most people. According to a study run by Michael Oehler, a professor at the University of Cologne , Germany, humans are "predisposed to detest" the sound of nails on a blackboard. The findings of the study were presented at the Acoustical Society of America conference and support earlier findings from a 1986 study by Vanderbilt psychologist Randolph Blake and two colleagues found that
1725-806: A special blackboard eraser usually consisting of a block of wood covered by a felt pad. However, chalk marks made on some types of wet blackboard can be difficult to remove. Blackboard manufacturers often advise that a new or newly resurfaced blackboard be completely covered using the side of a stick of chalk and then that chalk brushed off as normal to prepare it for use. Chalk sticks are produced in white and in various colours, especially for use with blackboards. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk or limestone, while coloured chalk sticks are made from calcium sulphate in its dihydrate form, CaSO 4 ·2H 2 O, derived from gypsum . Chalk sticks containing calcium carbonate typically contain 40–60% of CaCO 3 ( calcite ). On
1840-735: A variant of the early Greek alphabet, gave rise to the Etruscan alphabet and its own descendants, such as the Latin alphabet and Runes . Other descendants from the Greek alphabet include Cyrillic , used to write Bulgarian , Russian and Serbian , among others. The Phoenician system was also adapted into the Aramaic script , from which the Hebrew and the Arabic scripts are descended. The Tifinagh script (Berber languages)
1955-409: A vast array of topics of Indian culture, including descriptions of their traditions and customs. Although he tried to stay away from political and military history, Biruni did indeed record important dates and noted actual sites of where significant battles occurred. Additionally, he chronicled stories of Indian rulers and told of how they ruled over their people with their beneficial actions and acted in
2070-602: A white material from the left to the right. The first classroom uses of large blackboards are difficult to date, but they were used for music education and composition in Europe as far back as the 16th century. The term "blackboard" is attested in English from the mid-18th century; the Oxford English Dictionary provides a citation from 1739, to write "with Chalk on a black-Board". The first attested use of chalk on blackboard in
2185-430: Is a cognitive and social activity involving neuropsychological and physical processes . The outcome of this activity, also called "writing", and sometimes a " text ", is a series of physically inscribed , mechanically transferred , or digitally represented symbols. The interpreter or activator of a text is called a "reader". In general, writing systems do not constitute languages in and of themselves, but rather
2300-488: Is a set of written symbols that represent consonants and vowels . In a perfectly phonological alphabet, the letters would correspond perfectly to the language's phonemes . Thus, a writer could predict the spelling of a word given its pronunciation, and a speaker could predict the pronunciation of a word given its spelling. However, as languages often evolve independently of their writing systems, and writing systems have been borrowed for languages they were not designed for,
2415-627: Is also used to create custom chalkboard art . Blackboards on an A-frame are used by restaurants and bars to advertise daily specials. Adhesive chalkboard surface is also available in stores as rolls of textured black plastic shelf covering, which is applied to the desired wall, door or other surface. A more modern variation consists of a coiled sheet of plastic drawn across two parallel rollers, which can be scrolled to create additional writing space while saving what has been written. The highest grade blackboards are made of porcelain-enameled steel (black, green, blue or sometimes other colours). Porcelain

#17328548679462530-403: Is as yet undeciphered. The term 'Indus script' is mainly applied to that used in the mature Harappan phase, which perhaps evolved from a few signs found in early Harappa after 3500 BC. The script is written from right to left, and sometimes follows a boustrophedonic style. In 2015, the epigrapher Bryan Wells estimated there were around 694 distinct signs. This is above 400, so scholars accept
2645-650: Is co-extensive with uses of writing and the elaboration of activity systems that give rise to and circulate writing. Individual motivations for writing include improvised additional capacity for the limitations of human memory (e.g. to-do lists , recipes , reminders, logbooks , maps , the proper sequence for a complicated task or important ritual ), dissemination of ideas and coordination (e.g. essays , monographs , broadsides , plans , petitions , or manifestos ), creativity and storytelling , maintaining kinship and other social networks, business correspondence regarding goods and services, and life writing (e.g.
2760-477: Is descended from the Libyco-Berber script , which is assumed to be of Phoenician origin. In the history of writing , religious texts or writing have played a special role. For example, some religious text compilations have been some of the earliest popular texts, or even the only written texts in some languages, and in some cases are still highly popular around the world. The first books printed widely using
2875-475: Is difficult to read in the dark. Chalk sticks shrink through use, and are notorious for breaking in half unless inserted in a writing utensil designed for chalk. Blackboards can suffer from ghosting. Ghosting occurs when old coloured chalk, pastels or chalkpen ink absorbs into the black finish of the board, making it impossible to remove. The scratching of fingernails on a blackboard , as well as other pointed, especially metal objects against blackboards, produces
2990-509: Is explicitly directed toward the learning of writing, but much is focused more on subject learning. Writing systems may be broadly classified according to what units of language are represented by its symbols: alphabets and syllabaries generally represent a language's sounds of speech ( phonemes and syllables respectively)—while logographies represent a language's units of meaning ( words or morphemes ), though these are still associated by readers with their given pronunciations in
3105-517: Is not an independent glyph for each syllable. While research into the development of writing during the Neolithic is ongoing, the current consensus is that it first evolved from economic necessity in the ancient Near East . Writing most likely began as a consequence of political expansion in ancient cultures, which needed reliable means for transmitting information, maintaining financial accounts, keeping historical records, and similar activities. Around
3220-508: Is not only the main deliverable but also the mode of work itself. Even in occupations not typically associated with writing, routine records management has most employees writing at least some of the time. Some professions are typically associated with writing, such as literary authors, journalists, and technical writers, but writing is pervasive in most modern forms of work, civic participation, household management, and leisure activities. Writing permeates everyday commerce. For example, in
3335-552: Is one, eternal, and omnipotent and eschewing all forms of idol worship. He recognizes that uneducated Hindus worshiped a multiplicity of idols yet points out that even some Muslims (such as the Jabriyah ) have adopted anthropomorphic concepts of God. Al-Biruni wrote about the peoples, customs and religions of the Indian subcontinent. According to Akbar S. Ahmed, like modern anthropologists, he engaged in extensive participant observation with
3450-450: Is part of the autonomous republic of Karakalpakstan in northwest Uzbekistan . His name was most commonly latinized as Alberonius . Al-Biruni spent the first twenty-five years of his life in Khwarezm where he studied Islamic jurisprudence , theology, grammar, mathematics, astronomy , medicine and philosophy and dabbled not only in the field of physics, but also in those of most of

Arguments, experiments, observational data, and other evidence collated in the course of research is represented in writing, and serves as the basis for later work. Data collection and drafting of manuscripts may be supported by grants, which usually require proposals establishing the value of such work and the need for funding. The data and procedures are also typically collected in lab notebooks or other preliminary files. Preprints of potential publications may also be presented at academic or disciplinary conferences or on publicly accessible web servers to gain peer feedback and build interest in

The lecturer then moves boards into reach for writing and then moves them out of reach, allowing a large amount of material to be shown simultaneously. The chalk marks can be easily wiped off with a damp cloth, a sponge or

In 998, he went to the court of the Ziyarid amir of Tabaristan , Qabus ( r. 977–981, 997–1012 ). There he wrote his first important work, al-Athar al-Baqqiya 'an al-Qorun al-Khaliyya ("The remaining traces of past centuries", translated as "Chronology of ancient nations" or "Vestiges of

Of the 146 books written by al-Bīrūnī, 95 are devoted to astronomy, mathematics, and related subjects like mathematical geography. He lived during the Islamic Golden Age, when the Abbasid Caliphs promoted astronomical research, because such research possessed not only

He has been portrayed by Cüneyt Uzunlar in
4485-481: The Sumerian language and Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of ancestral proto-writing systems between 3400 and 3300 BC, with earliest coherent texts from c. 2600 BC . It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or
4600-544: The development of writing were driven by pragmatic exigencies like keeping track of produce and other wealth, recording history , maintaining culture , codifying knowledge through curricula and lists of texts deemed to contain foundational knowledge (e.g. The Canon of Medicine ) or artistic value (e.g. the literary canon ), organizing and governing societies through texts including legal codes , census records, contracts , deeds of ownership, taxation , trade agreements , and treaties . As Charles Bazerman explains,

In the US green porcelain enamelled boards started to appear at schools in 1950s. Writing Writing is the act of creating a persistent representation of human language . A writing system uses a set of symbols and rules to encode aspects of spoken language, such as its lexicon and syntax . However, written language may take on characteristics distinct from those of any spoken language. Writing

Over the centuries, three distinct Elamite scripts developed. Proto-Elamite is the oldest known writing system from Iran. In use only briefly ( c. 3200 – c. 2900 BC ), clay tablets with Proto-Elamite writing have been found at different sites across Iran, with

Biruni also employed astronomy in the determination of his theories, which were complex mathematical equations and scientific calculation that allows one to convert dates and years between the different calendars. The book does not limit itself to tedious records of battle because Biruni found the social culture to be more important. The work includes research on

During his journey through India, military and political history were not Biruni's main focus: he decided rather to document the civilian and scholarly aspects of Hindu life, examining culture, science, and religion. He explored religion within

Accepting the definite demise of the Afrighids at the hands of the Ma'munids, he made peace with the latter who then ruled Khwarezm . Their court at Gorganj (also in Khwarezm) was gaining fame for its gathering of brilliant scientists. In 1017, Mahmud of Ghazni captured Rey. Most scholars, including al-Biruni, were taken to Ghazni,

The last cuneiform scripts in Akkadian discovered thus far date from the 1st century AD. The earliest known hieroglyphs are about 5,200 years old, such as the clay labels of a Predynastic ruler called "Scorpion I" (Naqada IIIA period, c. 32nd century BC ) recovered at Abydos (modern Umm el-Qa'ab) in 1998 or

He further argued that stating there is a change in the creator would mean there is a change in the effect (meaning the universe has change) and that the universe coming into being after not being is such a change (and so arguing there is no change – no beginning – means Aristotle believes the creator is negated). Al-Biruni was proud of

The earliest surviving examples of writing in China—inscriptions on oracle bones , usually tortoise plastrons and ox scapulae which were used for divination—date from around 1200 BC, during the Late Shang period. A small number of bronze inscriptions from the same period have also survived. In 2003, archaeologists reported discoveries of isolated tortoise-shell carvings dating back to

He was 44 when he went on the journeys with Mahmud of Ghazni. Biruni became acquainted with all things related to India. During this time he wrote his study of India, finishing it around 1030. Along with his writing, Al-Biruni also made sure to extend his study to science while on

To avoid making a picture for each instance of the same object (for example: 100 pictures of a hat to represent 100 hats), they counted the objects by using various small marks. In this way the Sumerians added "a system for enumerating objects to their incipient system of symbols". The original Mesopotamian writing system

In most of the alphabets of the Middle East, it is usually only the consonants of a word that are written, although vowels may be indicated by the addition of various diacritical marks. Writing systems based primarily on writing just consonants phonemes date back to

Al-Biruni contributed to the introduction of the scientific method to medieval mechanics . He developed experimental methods to determine density, using a particular type of hydrostatic balance . Al-Biruni's method of using the hydrostatic balance was precise, and he

During the course of a day or even a single episode of writing, for example, a writer might instinctively switch among a pencil, a touchscreen, a text-editor, a whiteboard, a legal pad, and adhesive notes as different purposes arise. As human societies emerged, collective motivations for

In most of the alphabets of India and Southeast Asia , vowels are indicated through diacritics or modification of the shape of the consonant. These are called abugidas . Some abugidas, such as Geʽez and the Canadian Aboriginal syllabics , are learned by children as syllabaries, and so are often called "syllabics". However, unlike true syllabaries, there

Many modern systems of government are organized and sanctified through written constitutions at the national and sometimes state or other organizational levels. Written rules and procedures typically guide the operations of the various branches, departments, and other bodies of government, which regularly produce reports and other documents as work products and to account for their actions. In addition to legislatures that draft and pass laws, these laws are administered by an executive branch , which can present further written regulations specifying
8280-929: The interests of the nation. His details are brief and mostly just list rulers without referring to their real names, and he did not go on about deeds that each one carried out during their reign, which keeps in line with Biruni's mission to try to stay away from political histories. Biruni also described the geography of India in his work. He documented different bodies of water and other natural phenomena. These descriptions are useful to today's modern historians because they are able to use Biruni's scholarship to locate certain destinations in modern-day India. Historians are able to make some matches while also concluding that certain areas seem to have disappeared and been replaced with different cities. Different forts and landmarks were able to be located, legitimizing Biruni's contributions with their usefulness to even modern history and archeology. The dispassionate account of Hinduism given by Biruni
8395-418: The laws and how they are carried out. Governments at different levels also typically maintain written records on citizens concerning identities, life events such as births, deaths, marriages, and divorces, the granting of licenses for controlled activities, criminal charges, traffic offenses, and other penalties small and large, and tax liability and payments. Research undertaken in academic disciplines
8510-441: The learning of writing, and students may carry these particular associations long after leaving school. Alongside the writing that students read (in the forms of textbooks, assigned books, and other instructional materials as well as self-selected books) students do much writing within schools at all levels, on subject exams, in essays, in taking notes, in doing homework, and in formative and summative assessments . Some of this
8625-423: The length of various historical eras. Biruni is widely considered to be one of the most important Muslim authorities on the history of religion. He is known as a pioneer in the field of comparative religion in his study of, among other creeds, Zoroastrianism , Judaism, Hinduism , Christianity, Buddhism and Islam . He assumed the superiority of Islam: "We have here given an account of these things in order that
8740-567: The majority having been excavated at Susa , an ancient city located east of the Tigris and between the Karkheh and Dez Rivers. The Proto-Elamite script is thought to have developed from early cuneiform (proto-cuneiform). The Proto-Elamite script consists of more than 1,000 signs and is thought to be partly logographic . Linear Elamite is a writing system attested in a few monumental inscriptions in Iran. It
8855-442: The midst of a world of clashing swords, burning towns, and plundered temples." Biruni's writing was very poetic, which may diminish some of the historical value of the work for modern times. The lack of description of battle and politics makes those parts of the picture completely lost. However, many have used Biruni's work to check facts of history in other works that may have been ambiguous or had their validity questioned. Most of
8970-570: The one that appears to have been best developed, and the only one to be deciphered, is the Maya script . The earliest inscription identified as Maya dates to the 3rd century BC. Maya writing used logograms complemented by a set of syllabic glyphs, somewhat similar in function to modern Japanese writing. In 2001, archaeologists discovered that there was a civilization in Central Asia that used writing c. 2000 BC . An excavation near Ashgabat ,
9085-496: The other hand, chalk produces dust, the amount depending on the quality of chalk used. Some people find this uncomfortable or may be allergic to it, and according to the American Academy of Allergy, Asthma and Immunology (AAAAI), there are links between chalk dust and allergy and asthma problems. The dust also precludes the use of chalk in areas shared with dust-sensitive equipment such as computers . The writing on blackboards
9200-461: The other sciences. The Iranian Khwarezmian language , which was Biruni's mother tongue, survived for several centuries after Islam until the Turkification of the region – at least some of the culture of ancient Khwarezm endured – for it is hard to imagine that the commanding figure of Biruni, a repository of so much knowledge, should have appeared in a cultural vacuum. He was sympathetic to
9315-412: The other. There are, however, other reasons which make it impossible. This question is most difficult to solve. The most prominent of both modern and ancient astronomers have deeply studied the question of the moving of the earth, and tried to refute it. We, too, have composed a book on the subject called Miftah-ilm-alhai'a (Key to Astronomy) , in which we think we have surpassed our predecessors, if not in
9430-423: The philosopher Ibn Sina in a multiple letter correspondence. Al-Biruni stated: "Other people, besides, hold this foolish persuasion, that time has no terminus quo at all." He further stated that Aristotle , whose arguments Avicenna uses, contradicted himself when he stated that the universe and matter has a start whilst holding on to the idea that matter is pre-eternal. In his letters to Avicenna, he stated
9545-447: The phonetic Hangul system is mainly used. Other logographic systems include cuneiform and Maya . A syllabary is a set of written symbols that represent syllables , typically a consonant followed by a vowel, or just a vowel alone. In some scripts more complex syllables (such as consonant-vowel-consonant, or consonant-consonant-vowel) may have dedicated glyphs. Phonetically similar syllables are not written similarly. For instance,
9660-474: The radius of the Earth using measurements of the height of a hill and measurement of the dip in the horizon from the top of that hill. His calculated radius for the Earth of 3928.77 miles was 2% higher than the actual mean radius of 3847.80 miles. His estimate was given as 12,803,337 cubits , so the accuracy of his estimate compared to the modern value depends on what conversion is used for cubits. The exact length of
9775-524: The reader may learn by the comparative treatment of the subject how much superior the institutions of Islam are, and how more plainly this contrast brings out all customs and usages, differing from those of Islam, in their essential foulness." However he was happy on occasion to express admiration for other cultures, and quoted directly from the sacred texts of other religions when reaching his conclusions. He strove to understand them on their own terms rather than trying to prove them wrong. His underlying concept
9890-948: The reader the theories of the Hindus exactly as they are, and I shall mention in connection with them similar theories of the Greeks in order to show the relationship existing between them. An example of Biruni's analysis is his summary of why many Hindus hate Muslims. Biruni notes in the beginning of his book how the Muslims had a hard time learning about Hindu knowledge and culture. He explains that Hinduism and Islam are totally different from each other. Moreover, Hindus in 11th century India had suffered waves of destructive attacks on many of its cities, and Islamic armies had taken numerous Hindu slaves to Persia, which – claimed Biruni – contributed to Hindus becoming suspicious of all foreigners, not just Muslims. Hindus considered Muslims violent and impure, and did not want to share anything with them. Over time, Biruni won
10005-445: The sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, Al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he
10120-473: The scientific language of his age, but al-Tafhim is one of the most important of the early works of science in Persian , and is a rich source for Persian prose and lexicography . The book covers the Quadrivium in a detailed and skilled fashion. Following Al-Biruni's death, his work was neither built upon or referenced by scholars. Centuries later, his writings about India, which had become of interest to
10235-446: The script to be logo-syllabic (typically syllabic scripts have about 50–100 signs whereas logographic scripts have a very large number of principal signs). Several scholars maintain that structural analysis indicates an agglutinative language underlies the script. The Proto-Sinaitic script, in which Proto-Canaanite is believed to have been first written, is attested as far back as the 19th century BC. The Phoenician writing system
10350-461: The service of temple, pharaonic, and military authorities. The hieroglyph system was always difficult to learn, but in later centuries was purposely made even more so, as this preserved the scribes' status. The world's oldest known alphabet appears to have been developed by Canaanite turquoise miners in the Sinai desert around the mid-19th century BC. Around 30 crude inscriptions have been found at
10465-473: The sound of nails on a chalkboard annoyed people even when the high-pitch frequencies were removed. The study earned Blake a 2006 Ig Nobel Prize . The writing slate was in use in Indian schools as mentioned in Alberuni 's Indica ( Tarikh Al-Hind ), written in the early 11th century: They use black tablets for the children in the schools, and write upon them along the long side, not the broadside, writing with
10580-557: The specific aspects of Hindu life that Biruni studied was the Hindu calendar . His scholarship on the topic exhibited great determination and focus, not to mention the excellence in his approach of the in-depth research he performed. He developed a method for converting the dates of the Hindu calendar to the dates of the three different calendars that were common in the Islamic countries of his time period,
10695-501: The syllable "ka" may look nothing like the syllable "ki", nor will syllables with the same vowels be similar. Syllabaries are best suited to languages with a relatively simple syllable structure, such as Japanese. Other languages that use syllabic writing include Mycenaean Greek ( Linear B ), Cherokee , the Ndjuka creole language of Suriname , and the Vai language of Liberia . An alphabet
10810-701: The term cuneiform ), at first only for logograms , but by the 29th century BC also for phonetic elements. Around 2700 BC, cuneiform began to represent syllables of spoken Sumerian. About that time, Mesopotamian cuneiform became a general purpose writing system for logograms, syllables, and numbers. This script was adapted to another Mesopotamian language, the East Semitic Akkadian ( Assyrian and Babylonian ) c. 2600 BC , and then to others such as Elamite , Hattian , Hurrian and Hittite . Scripts similar in appearance to this writing system include those for Ugaritic and Old Persian . With
10925-509: The topic of density, including the different types of densities and how they are measured. His work on the subject was very influential and was later used by scientists like Galileo and Newton in their own research. Bīrūnī devised a novel method of determining the Earth's radius by means of the observation of the height of a mountain. He carried it out at Nandana in Pind Dadan Khan (present-day Pakistan). He used trigonometry to calculate
11040-587: The true value. In his Codex Masudicus (1037), Al-Biruni theorized the existence of a landmass along the vast ocean between Asia and Europe, or what is today known as the Americas. He argued for its existence on the basis of his accurate estimations of the Earth's circumference and Afro-Eurasia 's size, which he found spanned only two-fifths of the Earth's circumference, reasoning that the geological processes that gave rise to Eurasia must surely have given rise to lands in
11155-590: The vast ocean between Asia and Europe. He also theorized that at least some of the unknown landmass would lie within the known latitudes which humans could inhabit, and therefore would be inhabited. Biruni wrote a pharmacopoeia , the Kitab al-saydala fi al-tibb (" Book on the Pharmacopoeia of Medicine "). It lists synonyms for drug names in Syriac, Persian, Greek, Baluchi, Afghan, Kurdi, and some Indian languages. He used
11270-524: The ways in which writers have framed the experience of writing with such tools as compared with the pen or pencil. Advancements in natural language processing and natural language generation have resulted in software capable of producing certain forms of formulaic writing (e.g., weather forecasts and brief sports reporting) without the direct involvement of humans after initial configuration or, more commonly, to be used to support writing processes such as generating initial drafts, producing feedback with
11385-473: The welcome of Hindu scholars. Al-Biruni collected books and studied with these Hindu scholars to become fluent in Sanskrit, discover and translate into Arabic the mathematics, science, medicine, astronomy and other fields of arts as practiced in 11th-century India. He was inspired by the arguments offered by Indian scholars who believed earth must be globular in shape, which they felt was the only way to fully explain
11500-576: The words, at all events in the matter. In his major astronomical work, the Mas'ud Canon , Biruni observed that, contrary to Ptolemy , the Sun's apogee (highest point in the heavens) was mobile, not fixed. He wrote a treatise on the astrolabe , describing how to use it to tell the time and as a quadrant for surveying. One particular diagram of an eight-geared device could be considered an ancestor of later Muslim astrolabes and clocks. More recently, Biruni's eclipse data
11615-479: The work. Prior to official publication, these documents are typically read and evaluated by peer review from appropriate experts, who determine whether the work is of sufficient value and quality to be published. Publication does not establish the claims or findings of work as being authoritatively true, only that they are worth the attention of other specialists. As the work appears in review articles, handbooks, textbooks, or other aggregations, and others cite it in
11730-581: The works of Al-Biruni are in Arabic although he seemingly wrote the Kitab al-Tafhim in both Persian and Arabic, showing his mastery over both languages. Bīrūnī's catalogue of his own literary production up to his 65th lunar/63rd solar year (the end of 427/1036) lists 103 titles divided into 12 categories: astronomy, mathematical geography, mathematics, astrological aspects and transits, astronomical instruments, chronology, comets, an untitled category, astrology, anecdotes, religion, and books he no longer possesses. Biruni wrote most of his works in Arabic ,
11845-489: Was a Khwarazmian Iranian scholar and polymath during the Islamic Golden Age . He has been called variously "Father of Comparative Religion ", "Father of modern geodesy ", Founder of Indology and the first anthropologist . Al-Biruni was well versed in physics , mathematics, astronomy , and natural sciences , and also distinguished himself as a historian, chronologist , and linguist . He studied almost all
11960-623: Was a case of cultural diffusion . Archaeologist Denise Schmandt-Besserat determined the link between previously uncategorized clay "tokens", the oldest of which have been found in the Zagros region of Iran, and cuneiform, the first known writing. Around 8000 BC, Mesopotamians began using clay tokens to count their agricultural and manufactured goods. Later they began placing these tokens inside large, hollow clay containers (bulla, or globular envelopes) which were then sealed. The quantity of tokens in each container came to be expressed by impressing, on
12075-430: Was able to measure the density of many different substances, including precious metals, gems, and even air. He also used this method to determine the radius of the earth, which he did by measuring the angle of elevation of the horizon from the top of a mountain and comparing it to the angle of elevation of the horizon from a nearby plain. In addition to developing the hydrostatic balance, Al-Biruni also wrote extensively on
12190-505: Was adapted from the Proto-Canaanite script sometime before the 14th century BC, which in turn borrowed principles of representing phonetic information from Egyptian hieroglyphs . This writing system was an odd sort of syllabary in which only consonants are represented. This script was adapted by the Greeks , who adapted certain consonantal signs to represent their vowels. The Cumae alphabet ,
12305-688: Was conversant in Khwarezmian , Persian , Arabic, and Sanskrit , and also knew Greek , Hebrew , and Syriac . He spent much of his life in Ghazni , then capital of the Ghaznavids , in modern-day central-eastern Afghanistan. In 1017, he travelled to the Indian subcontinent and wrote a treatise on Indian culture entitled Tārīkh al-Hind (" The History of India "), after exploring the Hindu faith practiced in India. He was, for his time, an admirably impartial writer on
12420-491: Was derived c. 3200 BC from this method of keeping accounts. By the end of the 4th millennium BC, the Mesopotamians were using a triangular-shaped stylus pressed into soft clay to record numbers. This system was gradually augmented with using a sharp stylus to indicate what was being counted by means of pictographs . Round and sharp styluses were gradually replaced for writing by wedge-shaped styluses (hence
12535-608: Was not until the 12th to 9th centuries, however, that the alphabet took hold and became widely used. The Cascajal Block , a stone slab with 3,000-year-old proto-writing, was discovered in the Mexican state of Veracruz and is an example of the oldest script in the Western Hemisphere, preceding the oldest Zapotec writing by approximately 500 years. It is thought to be Olmec . Of several pre-Columbian scripts in Mesoamerica ,
12650-496: Was remarkable for its time. He stated that he was fully objective in his writings, remaining unbiased like a proper historian should. Biruni documented everything about India just as it happened. But, he did note how some of the accounts of information that he was given by natives of the land may not have been reliable in terms of complete accuracy, however, he did try to be as honest as possible in his writing. Eduard Sachau compares it to "a magic island of quiet, impartial research in
12765-440: Was that all cultures are at least distant relatives of all other cultures because they are all human constructs. "Rather, what Al-Biruni seems to be arguing is that there is a common human element in every culture that makes all cultures distant relatives, however foreign they might seem to one another." Al-Biruni divides Hindus into an educated and an uneducated class. He describes the educated as monotheistic, believing that God
12880-522: Was used by Dunthorne in 1749 to help determine the acceleration of the Moon , and his data on equinox times and eclipses was used as part of a study of Earth's past rotation. Like later adherents of the Ash'ari school, such as al-Ghazali , al-Biruni is famous for vehemently defending the majority Sunni position that the universe had a beginning, being a strong supporter of creatio ex nihilo , specifically refuting
12995-417: Was used for a very brief period during the last quarter of the 3rd millennium BC. It is often claimed that Linear Elamite is a syllabic writing system derived from Proto-Elamite, although this cannot be proven since Linear-Elamite has not been deciphered. Several scholars have attempted to decipher the script, most notably Walther Hinz [ de ] and Piero Meriggi . The Elamite cuneiform script
13110-501: Was used from about 2500 to 331 BC, and was adapted from the Akkadian cuneiform. At any given point within this period, the Elamite cuneiform script consisted of about 130 symbols, and over this entire period only 206 total signs were used. This is far fewer than most other cuneiform scripts. Cretan hieroglyphs are found on artifacts of Crete (early-to-mid-2nd millennium BC, MM I to MM III, overlapping with Linear A from MM IIA at
13225-647: Was used in the Aegean Islands ( Kea , Kythera , Melos , Thera ), and the Greek mainland ( Laconia ) from c. 18th century to 1450 BC; and Linear B was used in Crete ( Knossos ), and mainland ( Pylos , Mycenae , Thebes , Tiryns ) from c. 1375 to 1200 BC. Indus script refers to short strings of symbols associated with the Indus Valley Civilization (which spanned modern-day Pakistan and North India ) used between 2600 and 1900 BC. Despite attempts at decipherments and claims, it
