Human
–
Modern humans are the only extant members of Hominina tribe, a branch of the tribe Hominini belonging to the family of great apes. Several of these hominins used fire, occupied much of Eurasia and they began to exhibit evidence of behavioral modernity around 50,000 years ago. In several waves of migration, anatomically modern humans ventured out of Africa, the spread of humans and their large and increasing population has had a profound impact on large areas of the environment and millions of native species worldwide. Humans are uniquely adept at utilizing systems of communication for self-expression and the exchange of ideas. Humans create complex structures composed of many cooperating and competing groups, from families. Social interactions between humans have established a wide variety of values, social norms, and rituals. These human societies subsequently expanded in size, establishing various forms of government, religion, today the global human population is estimated by the United Nations to be near 7.5 billion. In common usage, the word generally refers to the only extant species of the genus Homo—anatomically and behaviorally modern Homo sapiens. In scientific terms, the meanings of hominid and hominin have changed during the recent decades with advances in the discovery, there is also a distinction between anatomically modern humans and Archaic Homo sapiens, the earliest fossil members of the species. The English adjective human is a Middle English loanword from Old French humain, ultimately from Latin hūmānus, the words use as a noun dates to the 16th century. The native English term man can refer to the species generally, the species binomial Homo sapiens was coined by Carl Linnaeus in his 18th century work Systema Naturae. The generic name Homo is a learned 18th century derivation from Latin homō man, the species-name sapiens means wise or sapient. Note that the Latin word homo refers to humans of either gender, the genus Homo evolved and diverged from other hominins in Africa, after the human clade split from the chimpanzee lineage of the hominids branch of the primates. The closest living relatives of humans are chimpanzees and gorillas, with the sequencing of both the human and chimpanzee genome, current estimates of similarity between human and chimpanzee DNA sequences range between 95% and 99%. The gibbons and orangutans were the first groups to split from the leading to the humans. The splitting date between human and chimpanzee lineages is placed around 4–8 million years ago during the late Miocene epoch, during this split, chromosome 2 was formed from two other chromosomes, leaving humans with only 23 pairs of chromosomes, compared to 24 for the other apes. There is little evidence for the divergence of the gorilla, chimpanzee. Each of these species has been argued to be an ancestor of later hominins

Artery
–
Arteries are blood vessels that carry blood away from the heart. While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries, the effective arterial blood volume is that extracellular fluid which fills the arterial system. The anatomy of arteries can be separated into gross anatomy, at the level, and microscopic anatomy. The outermost layer is known as the tunica externa, also known as tunica adventitia, inside this layer is the tunica media, or media, which is made up of smooth muscle cells and elastic tissue. The innermost layer, which is in contact with the flow of blood, is the tunica intima. This layer is made up of endothelial cells. The hollow internal cavity in which the flows is called the lumen. Arterial formation begins when endothelial cells begin to express specific genes. Arteries form part of the circulatory system and they carry blood that is oxygenated after it has been pumped from the heart. Arteries also aid the heart in pumping blood, arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation. Veins and pulmonary veins carry deoxygenated blood. )The pulmonary artery carries blood from the heart to the lungs and it is unique because the blood in it is not oxygenated, as it has not yet passed through the lungs. The other unique artery is the artery, which carries deoxygenated blood from a fetus to its mother. Arteries have a blood pressure than other parts of the circulatory system. The pressure in arteries varies during the cardiac cycle and it is highest when the heart contracts and lowest when heart relaxes. The variation in pressure produces a pulse, which can be felt in different areas of the body, arterioles have the greatest collective influence on both local blood flow and on overall blood pressure. They are the primary adjustable nozzles in the system, across which the greatest pressure drop occurs. The larger arteries are generally elastic and the smaller ones tend to be muscular, systemic arteries deliver blood to the arterioles, and then to the capillaries, where nutrients and gases are exchanged. After travelling from the aorta, blood travels through peripheral arteries into smaller arteries called arterioles, arterioles help in regulating blood pressure by the variable contraction of the smooth muscle of their walls, and deliver blood to the capillaries
3.
Vein
–
Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the back to the heart, exceptions are the pulmonary and umbilical veins. In contrast to veins, arteries carry blood away from the heart, veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow, veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, superficial veins are those closer to the surface of the body, and have no corresponding arteries. Deep veins are deeper in the body and have corresponding arteries, perforator veins drain from the superficial to the deep veins. These are usually referred to in the limbs and feet. Communicating veins are veins that directly connect superficial veins to deep veins, pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart. Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart, most veins are equipped with valves to prevent blood flowing in the reverse direction. Veins appear blue because the subcutaneous fat absorbs low-frequency light, permitting only the highly energetic blue wavelengths to penetrate through to the dark vein and reflect back to the viewer. The colour of a vein can be affected by the characteristics of a skin, how much oxygen is being carried in the blood. When a vein is drained of blood and removed from an organism, the largest veins in the human body are the venae cavae. These are two large veins which enter the right atrium of the heart from above and below. The superior vena cava carries blood from the arms and head to the atrium of the heart, while the inferior vena cava carries blood from the legs. The inferior vena cava is retroperitoneal and runs to the right, large veins feed into these two veins, and smaller veins into these. Together this forms the venous system, whilst the main veins hold a relatively constant position, the position of veins person to person can display quite a lot of variation. The pulmonary veins carry relatively oxygenated blood from the lungs to the heart, the superior and inferior venae cavae carry relatively deoxygenated blood from the upper and lower systemic circulations, respectively. The portal venous system is a series of veins or venules that directly connect two capillary beds, examples of such systems include the hepatic portal vein and hypophyseal portal system

Nerve
–
A nerve is an enclosed, cable-like bundle of axons in the peripheral nervous system. A nerve provides a pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs. In the central system, the analogous structures are known as tracts. Each nerve is a structure containing bundles of axons. Within a nerve, each axon is surrounded by a layer of tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of tissue called the perineurium. Finally, the nerve is wrapped in a layer of connective tissue called the epineurium. Efferent nerves conduct signals from the nervous system along motor neurons to their target muscles. Mixed nerves contain both afferent and efferent axons, and thus conduct both incoming sensory information and outgoing muscle commands in the same bundle and they are given letter-number designations according to the vertebra through which they connect to the spinal column. Cranial nerves innervate parts of the head, and connect directly to the brain and they are typically assigned Roman numerals from 1 to 12, although cranial nerve zero is sometimes included. In addition, cranial nerves have descriptive names, each nerve is covered externally by a dense sheath of connective tissue, the epineurium. Underlying this is a layer of cells, the perineurium. Perineurial septae extend into the nerve and subdivide it into several bundles of fibres, surrounding each such fibre is the endoneurium. This forms a tube from the surface of the spinal cord to the level where the axon synapses with its muscle fibres. The endoneurium consists of a sleeve of material called the glycocalyx. Nerves are bundled along with vessels, since the neurons of a nerve have fairly high energy requirements. Within the endoneurium, the nerve fibres are surrounded by a low protein liquid called endoneurial fluid. This acts in a way to the cerebrospinal fluid in the central nervous system

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Anatomical terminology
–
Anatomical terminology is a form of scientific terminology used by anatomists, zoologists, and health professionals such as doctors. Anatomical terminology uses many terms, suffixes, and prefixes deriving from Ancient Greek. These terms can be confusing to those unfamiliar with them, but can be more precise reducing ambiguity, also, since these anatomical terms are not used in everyday conversation, their meanings are less likely to change, and less likely to be misinterpreted. By using precise anatomical terminology such ambiguity is eliminated, an international standard for anatomical terminology, Terminologia Anatomica has been created. Anatomical terminology has quite regular morphology, the prefixes and suffixes are used to add meanings to different roots. The root of a term refers to an organ, tissue. For example, in the disorder hypertension, the prefix hyper- means high or over, the roots, prefixes and suffixes are often derived from Greek or Latin, and often quite dissimilar from their English-language variants. Latin names of such as musculus biceps brachii can be split up and refer to, musculus for muscle, biceps for two-headed. The first word tells us what we are speaking about, the second describes it, when describing the position of anatomical structures, structures may be described according to the anatomical landmark they are near. These landmarks may include structures, such as the umbilicus or sternum, or anatomical lines, the cephalon or cephalic region refers to the head. This area is differentiated into the cranium, facies, frons, oculus, auris, bucca, nausus, oris. The neck area is called the cervicis or cervical region, examples of structures named according to this include the frontalis muscle, submental lymph nodes, buccal membrane and orbicularis oculi muscle. Sometimes, unique terminology is used to reduce confusion in different parts of the body, for example, different terms are used when it comes to the skull in compliance with its embryonic origin and its tilted position compared to in other animals. Here, Rostral refers to proximity to the front of the nose, similarly, in the arms, different terminology is often used in the arms, in part to reduce ambiguity as what is the front, back, inner and outer surfaces. For this reason, the terms below are used, Radial referring to the radius bone, ulnar referring to the ulna bone, medially positioned when in the standard anatomical position. Other terms are used to describe the movement and actions of the hands and feet. International morphological terminology is used by the colleges of medicine and dentistry and it facilitates communication and exchanges between scientists from different countries of the world and it is used daily in the fields of research, teaching and medical care. The international morphological terminology refers to morphological sciences as a biological sciences branch, in this field, the form and structure are examined as well as the changes or developments in the organism

Digit (anatomy)
–
A digit is one of several most distal parts of a limb, such as fingers or toes, present in many vertebrates. Some languages have different names for hand and foot digits, in other languages, e. g. Humans normally have five digits on each extremity. Each digit is formed by bones called phalanges, surrounded by soft tissue. Human fingers normally have a nail at the distal phalanx, the phenomenon of polydactyly occurs when extra digits are present, the utility of such a mutation is case-dependent. The somatosensory cortex representation of the hand is a reflection of the fingers on the external hand. However, not only are the fingers of their hands fused, the fingers can be surgically divided to make a more useful hand. Surgeons did this at the Institute of Reconstructive Plastic Surgery in New York to a 32-year-old man with the initials O. G and they touched O. G. ’s fingers before and after surgery while using MRI brain scans. Before the surgery, the fingers mapped onto his brain were fused together, afterward. Two ideas about the homology of arms, hands and digits exist, first that digits are unique to tetrapods and second that antecedents were present in the fins of early sarcopterygian fish. Until recently it was concluded that Both genetic and fossil data support the hypothesis that digits are evolutionary novelties. p, for example, they had fin radials, bones similar to rudimentary fingers but positioned in the arm-like base of their fins. Thus there was in the evolution of tetrapods a shift such that the outermost part of the fins were lost, at any rate, it demonstrates that the fish–tetrapod transition was accompanied by significant character incongruence in functionally important structures. p. Birds and theropod dinosaurs have three digits on their hands, paradoxically the two digits that are missing are different, the bird hand is thought to derive from the second, third and fourth digits of the ancestral five-digit hand. In contrast, the dinosaurs seem to have the first, second. This suggests the evolution of digits in birds resulted from a shift in digit identity characterized early stages of theropod evolution Polydactyly in early tetrapods Polydactyly

Middle finger
–
The middle finger, long finger, or tall finger is the third digit of the human hand, located between the index finger and the ring finger. It is usually the longest finger, in anatomy, it is also called the third finger, digitus medius, digitus tertius, or digitus III. In Western countries, extending the finger is an offensive and obscene gesture. The middle finger is used for finger snapping together with the thumb
9.
Ring finger
–
The ring finger is the fourth proximal digit of the human hand, and the second most ulnar finger, located between the middle finger and the little finger. It is also called digitus medicinalis, the finger, digitus annularis, digitus quartus. It may also be referred to as the finger, excluding the thumb. According to László A. Magyar, the names of the finger in many languages reflect an ancient belief that it is a magical finger. It is named after magic or rings, or called nameless, in Sanskrit and other languages like Finnish or Russian, the ring finger is called respectively - Anamika, Nimetön and Безымянный. In Arabic and Hebrew, the finger is called respectively - bansur -. Before medical science discovered how the system functioned, people believed that a vein ran directly from the fourth finger on the left hand to the heart. Because of the connection, they chose the descriptive name vena amoris, Latin for the vein of love. Based upon this name, their contemporaries, purported experts in the field of matrimonial etiquette, wrote that it would only be fitting that the ring be worn on this finger. By wearing the ring on the finger of the left hand. In Western cultures, a ring is traditionally worn on the ring finger. This developed from the Roman anulus pronubis when the man gave a ring to the woman at the betrothal ceremony, blessing the wedding ring and putting it on the brides finger dates from the 11th century. In medieval Europe, the Christian wedding ceremony placed the ring in sequence on the thumb, index, middle, the ring was then left on the ring finger. In a few European countries, the ring is worn on the hand prior to marriage. For example, a Greek Orthodox bride wears the ring on the hand prior to the ceremony. In England, the 1549 Prayer Book declared the ring shall be placed on the left hand, by the 17th and 18th centuries the ring could be found on any finger after the ceremony — even on the thumb. The wedding ring is worn on the ring finger of the left hand in the former British Empire, certain parts of Western Europe, certain parts of Catholic Central and Eastern Europe. In Eastern Europe, these include, Bulgaria, Georgia, Latvia, Lithuania, Poland, Russia, Serbia, in Central or Western Europe, these include, Austria, Denmark, Greece, Germany, Hungary, Netherlands, Norway, and Spain

Digit ratio
–
The digit ratio is the ratio of the lengths of different digits or fingers typically measured from the midpoint of bottom crease to the tip of the finger. The 2D, 4D ratio is calculated by dividing the length of the finger of a given hand by the length of the ring finger of the same hand. A longer index finger will result in a higher than 1. A number of studies have shown a correlation between the 2D, 4D digit ratio and various physical and behavioral traits, in 1983 Dr Glenn Wilson of Kings College, London published a study examining the correlation between assertiveness in women and their digit ratio. This was the first study to examine the correlation between digit ratio and a trait within members of the same sex. Wilson proposed that skeletal structure and personality were simultaneously affected by sex hormone levels in utero, Manning and colleagues reported the sex difference in digit ratios was present in two-year-old children and further developed the idea that the index was a marker of prenatal sex hormones. Since then research on the topic has burgeoned around the world, a 2011 paper by Zhengui Zheng and Martin J. Cohn reports the 2D, 4D ratio in mice is controlled by the balance of androgen to estrogen signaling during a narrow window of digit development. The formation of the digits in humans, in utero, is thought to occur by 13 weeks, and the bone-to-bone ratio is consistent from this point into an individual’s adulthood. Importantly, there has no correlation between the sex hormone levels of an adult and the individual’s 2D, 4D, which implies that it is strictly the exposure in utero that causes this phenomenon. So there should be a correlation with one or the other, from a study of 136 males and 137 females at the University of Alberta, Males, mean 0.947, standard deviation 0.029. Females, mean 0.965, standard deviation 0.026, assuming a normal distribution, the above lead to 95% prediction intervals for 2D, 4D ratio of 0. 889-1.005 for males and 0. 913-1.017 for females. Women with congenital adrenal hyperplasia, which results in elevated androgen levels before birth, have lower, more masculinized 2D, other possible physiological effects include an enlarged clitoris and shallow vagina. These measures indicate that males with CAH are exposed to greater prenatal concentrations of total androgens than are control males, digit ratio in men with Klinefelters syndrome, who have reduced testosterone secretion throughout life compared to control males, are greater than in their fathers or control males. In a non-clinical sample of women, digit ratio correlated with distance in the expected direction. Women with a greater distance, indicating greater prenatal androgen exposure, had a smaller digit ratio. Digit ratio in men correlates with variation in the androgen receptor gene. Men with genes that produce androgen receptors that are sensitive to testosterone have greater, more feminine. There are reports of a failure to replicate this finding, thus, it is not clear that 2D, 4D would be expected to correlate with CAG repeats, even if it accurately reflects prenatal androgen

Phalanx bone
–
The phalanges /fəˈlæŋdʒiːz/ are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges, the phalanges are classed as long bones. The phalanges are the bones that make up the fingers of the hand, there are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, the middle and far phalanges of the fourth and fifth toes are often fused together. The phalanges of the hand are known as the finger bones. The phalanges of the foot differ from the hand in that they are shorter and more compressed, especially in the proximal phalanges. The phalanges are named according to whether they are proximal, intermediate or distal, the proximal phalanges are those that are closest to the hand or foot. In the hand, the prominent, knobby ends of the phalanx is often called the knuckle. The proximal phalanges join with the metacarpals of the hand or metatarsals of the foot at the joint or metatarsophalangeal joint. The intermediate phalanx is not only intermediate in location, but usually also in size, the thumb and large toe do not possess a middle phalanx. The distal phalanges are the bones at the tips of the fingers or toes, the proximal, intermediate, and distal phalanges articulate with one another through interphalangeal articulations. Each phalanx consists of a part, called the body. The body is flat on either side, concave on the palmar surface and its sides are marked with rough areas giving attachment to fibrous sheaths of flexor tendons. The proximal extremities of the bones of the first row present oval, concave articular surfaces, the proximal extremity of each of the bones of the second and third rows presents a double concavity separated by a median ridge. In the foot, the proximal phalanges have a body that is compressed from side to side, convex above, the base is concave, and the head presents a trochlear surface for articulation with the second phalanx. The middle are remarkably small and short, but rather broader than the proximal, in the hand, the distal phalanges are flat on their palmar surface, small, and with a roughened, elevated surface of horseshoe form on the palmar surface, supporting the finger pulp. The flat, wide expansions found at the tips of the phalanges are called apical tufts. They support the fingertip pads and nails, the phalanx of the thumb has a pronounced insertion for the flexor pollicis longus, an ungual fossa, and a pair of unequal ungual spines

Number
–
Numbers that answer the question How many. Are 0,1,2,3 and so on, when used to indicate position in a sequence they are ordinal numbers. To the Pythagoreans and Greek mathematician Euclid, the numbers were 2,3,4,5, Euclid did not consider 1 to be a number. Numbers like 3 +17 =227, expressible as fractions in which the numerator and denominator are whole numbers, are rational numbers and these make it possible to measure such quantities as two and a quarter gallons and six and a half miles. What we today would consider a proof that a number is irrational Euclid called a proof that two lengths arising in geometry have no common measure, or are incommensurable, Euclid included proofs of incommensurability of lengths arising in geometry in his Elements. In the Rhind Mathematical Papyrus, a pair of walking forward marked addition. They were the first known civilization to use negative numbers, negative numbers came into widespread use as a result of their utility in accounting. They were used by late medieval Italian bankers, by 1740 BC, the Egyptians had a symbol for zero in accounting texts. In Maya civilization zero was a numeral with a shape as a symbol. The ancient Egyptians represented all fractions in terms of sums of fractions with numerator 1, for example, 2/5 = 1/3 + 1/15. Such representations are known as Egyptian Fractions or Unit Fractions. The earliest written approximations of π are found in Egypt and Babylon, in Babylon, a clay tablet dated 1900–1600 BC has a geometrical statement that, by implication, treats π as 25/8 =3.1250. In Egypt, the Rhind Papyrus, dated around 1650 BC, astronomical calculations in the Shatapatha Brahmana use a fractional approximation of 339/108 ≈3.139. Other Indian sources by about 150 BC treat π as √10 ≈3.1622 The first references to the constant e were published in 1618 in the table of an appendix of a work on logarithms by John Napier. However, this did not contain the constant itself, but simply a list of logarithms calculated from the constant and it is assumed that the table was written by William Oughtred. The discovery of the constant itself is credited to Jacob Bernoulli, the first known use of the constant, represented by the letter b, was in correspondence from Gottfried Leibniz to Christiaan Huygens in 1690 and 1691. Leonhard Euler introduced the letter e as the base for natural logarithms, Euler started to use the letter e for the constant in 1727 or 1728, in an unpublished paper on explosive forces in cannons, and the first appearance of e in a publication was Eulers Mechanica. While in the subsequent years some researchers used the letter c, e was more common, the first numeral system known is Babylonian numeric system, that has a 60 base, it was introduced in 3100 B. C. and is the first Positional numeral system known

1 (number)
–
1, is a number, a numeral, and the name of the glyph representing that number. It represents a single entity, the unit of counting or measurement, for example, a line segment of unit length is a line segment of length 1. It is also the first of the series of natural numbers. The word one can be used as a noun, an adjective and it comes from the English word an, which comes from the Proto-Germanic root *ainaz. The Proto-Germanic root *ainaz comes from the Proto-Indo-European root *oi-no-, compare the Proto-Germanic root *ainaz to Old Frisian an, Gothic ains, Danish een, Dutch een, German eins and Old Norse einn. Compare the Proto-Indo-European root *oi-no- to Greek oinos, Latin unus, Old Persian aivam, Old Church Slavonic -inu and ino-, Lithuanian vienas, Old Irish oin, One, sometimes referred to as unity, is the first non-zero natural number. It is thus the integer before two and after zero, and the first positive odd number, any number multiplied by one is that number, as one is the identity for multiplication. As a result,1 is its own factorial, its own square, its own cube, One is also the result of the empty product, as any number multiplied by one is itself. It is also the natural number that is neither composite nor prime with respect to division. The Gupta wrote it as a line, and the Nagari sometimes added a small circle on the left. The Nepali also rotated it to the right but kept the circle small and this eventually became the top serif in the modern numeral, but the occasional short horizontal line at the bottom probably originates from similarity with the Roman numeral I. Where the 1 is written with an upstroke, the number 7 has a horizontal stroke through the vertical line. While the shape of the 1 character has an ascender in most modern typefaces, in typefaces with text figures, many older typewriters do not have a separate symbol for 1 and use the lowercase letter l instead. It is possible to find cases when the uppercase J is used,1 cannot be used as the base of a positional numeral system, as the only digit that would be permitted in such a system would be 0. Since the base 1 exponential function always equals 1, its inverse does not exist, there are two ways to write the real number 1 as a recurring decimal, as 1.000. and as 0.999. There is only one way to represent the real number 1 as a Dedekind cut, in a multiplicative group or monoid, the identity element is sometimes denoted 1, but e is also traditional. However,1 is especially common for the identity of a ring. When such a ring has characteristic n not equal to 0,1 is the first figurate number of every kind, such as triangular number, pentagonal number and centered hexagonal number, to name just a few

American manual alphabet
–
The American Manual Alphabet is a manual alphabet that augments the vocabulary of American Sign Language. The letters and digits are signed as follows, in informal contexts, the handshapes are not made as distinctly as they are in formal contexts. The manual alphabet can be used on hand, normally the signers dominant hand – that is, the right hand for right-handers. Both of these tracings are made as seen by the signer if right-handed, when signed with the left hand, the motions are in mirror image, therefore unreversed for the viewer. However, fluent signers do not need to read the shapes of these movements, in most drawings or illustrations of the American Manual Alphabet, some of the letters are depicted from the side to better illustrate the desired hand shape. For example, the letters G and H are frequently shown from the side to illustrate the position of the fingers, however, they are signed with the hand in an ergonomically neutral position, palm facing to the side and fingers pointing forward. Several letters have the hand shape, and are distinguished by orientation. These are h and u, k and p, g and q and, in contexts, d. In rapid signing, n is distinguished from h/u by orientation, the letters a and s have the same orientation, and are very similar in form. The thumb is on the side of the fist in the letter a, when fingerspelling, the hand is at shoulder height. It does not bounce with each letter unless a letter appears twice in a row, letters are signed at a constant speed, a pause functions as a word divider. The first letter may be held for the length of an extra as a cue that the signer is about to start fingerspelling.

Malays (ethnic group)
–
These locations today are part of the modern nations of Malaysia, Indonesia, Singapore, Brunei, and southern Thailand. In literature, architecture, culinary traditions, traditional dress, performing arts, martial arts, throughout their history, the Malays have been known as a coastal-trading community with fluid cultural characteristics. The epic literature, the Malay Annals, associates the etymological origin of Melayu to Sungai Melayu in Sumatra, the English term Malay was adopted via the Dutch word Malayo, itself derived from Portuguese, Malaio, which originates from the original Malay word, Melayu. Prior to the 15th century, the term Melayu and its variants appear to apply as an old toponym to the Strait of Malacca region in general. Malaya Dwipa, Malaya Dvipa, is described in chapter 48, Vayu Purana as one of the provinces in the sea that was full of gold. Some scholars equate the term with Sumatra, but several Indian scholars believe the term should refer to the mountainous Malay peninsula, maleu-kolon - appeared in Ptolemys work, Geographia. Mo-lo-yu - mentioned by Yijing, a Tang dynasty Chinese Buddhist monk who visited the Southeast Asia in 688–695, according to Yijing, the Mo-Lo-Yu kingdom was located in a distance of 15 day sail from Bogha, the capital of Sribhoga. It took a 15-day sail as well to reach Ka-Cha from Mo-lo-yu, therefore, a popular theory relates Mo-Lo-Yu with the Jambi in Sumatra, however the geographical location of Jambi contradicts with Yi Jings description of a half way sail between Ka-Cha and Bogha.

The southernmost point of continental Eurasia, Tanjung Piai, is in Malaysia, located in the tropics, Malaysia is one of 17 megadiverse countries on earth, with large numbers of endemic species. Malaysia has its origins in the Malay kingdoms present in the area which, from the 18th century, the first British territories were known as the Straits Settlements, whose establishment was followed by the Malay kingdoms becoming British protectorates. The territories on Peninsular Malaysia were first unified as the Malayan Union in 1946, Malaya was restructured as the Federation of Malaya in 1948, and achieved independence on 31 August 1957. Malaya united with North Borneo, Sarawak, and Singapore on 16 September 1963 to become Malaysia, less than two years later in 1965, Singapore was expelled from the federation.

Tawhid
–
Tawhid is the indivisible oneness concept of monotheism in Islam. Tawhid is the religions most fundamental concept and holds that God is One, because of the principle of Tawhid the Islamic belief in God is considered Unitarian. Tawhid constitutes the foremost article of the Muslim profession of faith, the first part of the Shahada is the declaration of belief in the oneness of God. To attribute divinity to an entity, known as shirk, is an unpardonable sin according to the Quran. Muslims believe that the entirety of the Islamic teaching rests on the principle of Tawhid, There is an uncompromising monotheism at the heart of the Islamic beliefs which is seen, from an Islamic standpoint, as distinguishing Islam from other major religions. The Quran asserts the existence of a single and absolute truth that transcends the world, a unique, independent and indivisible being, who is independent of the entire creation. God, according to Islam, is a universal God, rather than a local, tribal, or parochial one—God is an absolute, who integrates all affirmative values and brooks no evil. Islamic intellectual history can be understood as an unfolding of the manner in which successive generations of believers have understood the meaning. Islamic scholars have different approaches toward understanding it, Islamic theology, jurisprudence, philosophy, Sufism, even to some degree the Islamic understanding of natural sciences, all seek to explain at some level the principle of tawhid. The classical definition of tawhid was limited to declaring or preferring belief in one God, in modern Arabic, the verbs wahhada or yuwahhidu mean to unite or bring together something that which wasnt one, which reflects the struggle of monotheism against polytheism. Attribution of divinity to an entity, shirk, is considered a denial of the truth of God. Associating others with God is known as shirk and is the antithesis of Tawhid and it is usually but not always in the form of idolatry and supplicating to others than Allah, or believing that they hold the same attributes as him in an equal or lesser degree. Shirk is divided into two categories, Greater shirk, open and apparent, Lesser shirk, concealed or hidden, Greater Shirk consists of the above-mentioned deeds. A person commits lesser shirk or hidden polytheism when he claims to believe in God but his thoughts and actions do not reflect his belief. There are also forms of Shirk, they must be avoided as well. Within Islam, shirk is a crime, God may forgive any sin if one dies in that state except for committing shirk. Ali states that God is One means that God is away from likeness and numeration, the first step of religion is to accept, understand and realize him as the Lord. The correct form of belief in his unity is to realize that he is so absolutely pure and that is, one should realize that there is no difference between his person and his attributes, and his attributes should not be differentiated or distinguished from his person

Islamic State of Iraq and the Levant
–
ISIL gained global prominence in early 2014 when it drove Iraqi government forces out of key cities in its Western Iraq offensive, followed by its capture of Mosul and the Sinjar massacre. This group has been designated a terrorist organisation by the United Nations, ISIL is widely known for its videos of beheadings of both soldiers and civilians, including journalists and aid workers, and its destruction of cultural heritage sites. The United Nations holds ISIL responsible for human rights abuses and war crimes, ISIL originated as Jamaat al-Tawhid wal-Jihad in 1999, which pledged allegiance to al-Qaeda and participated in the Iraqi insurgency following the 2003 invasion of Iraq by Western forces. The group proclaimed itself a caliphate and began referring to itself as Islamic State or IS in June 2014. As a caliphate, it claims religious, political, and military authority over all Muslims worldwide and its adoption of the name Islamic State and its idea of a caliphate have been widely criticised, with the United Nations, various governments, and mainstream Muslim groups rejecting its statehood. As of 2015, ISIL is estimated to have a budget of more than USD$1 billion. In April 2013, having expanded into Syria, the group adopted the name ad-Dawlah al-Islāmiyah fī l-ʿIrāq wa-sh-Shām, while the use of either one or the other acronym has been the subject of debate, the distinction between the two and its relevance has been considered not so great. Of greater relevance is the name Daesh, which is an acronym of ISILs Arabic name al-Dawlah al-Islamīyah fī al-ʻIrāq wa-al-Shām. This name has been used by ISILs Arabic-speaking detractors, although – and to a certain extent because – it is considered derogatory, as it resembles the Arabic words Daes. Within areas under its control, ISIL considers use of the name Daesh punishable by flogging or cutting out the tongue, in late June 2014, the group renamed itself ad-Dawlah al-Islāmiyah, declaring itself a worldwide caliphate. The name Islamic State and the claim to be a caliphate have been widely rejected, with the UN, various governments. Frances Foreign Minister Laurent Fabius said This is a terrorist group, I do not recommend using the term Islamic State because it blurs the lines between Islam, Muslims, and Islamists. The Arabs call it Daesh and I will be calling them the Daesh cutthroats, the group is very sensitive about its name. They will cut your tongue out even if you call them ISIS – you have to say Islamic State, the Islamic State is mocked on social media websites such as Twitter and YouTube, with the use of hashtags, mock recruiting ads, fake news articles and YouTube videos. ISIL is a theocracy, proto-state and a Salafi or Wahhabi group and it follows an extremist interpretation of Islam, promotes religious violence, and regards Muslims who do not agree with its interpretations as infidels or apostates. According to some observers, ISIL emerged from the ideology of the Muslim Brotherhood and it adheres to global jihadist principles and follows the hard-line ideology of al-Qaeda and many other modern-day jihadist groups. However, other sources trace the roots to Wahhabism. For their guiding principles, the leaders of the Islamic State, are open and clear about their almost exclusive commitment to the Wahhabi movement of Sunni Islam

Subhan Allah
–
Subḥān Allāh is an Arabic phrase, meaning God is perfect. It is also known as Tasbih, the phrase can be roughly translated as Praised be God or Glory to God. The root of the word سبحان is derived from the word سبح, thus, it serves as testimony to Gods transcendence. For example, the Quran says SubhanAllahi ammaa yasifoon and SubhanAllah ammaa yushrikoon, the phrase is mentioned in the hadith Sahih Bukhari, VBN5,57,50. There is no counterpart for this phrase in the English language. It is also often cited during the Islamic prayer, or during the sermon in the mosque, qul hāḏihi sabīl-ī ʾadʿū ʾilā l-lāhi ʿalā baṣīratin ʾanā wa-mani ttabaʿa-nī wa-subḥāna llāhi wa-mā ʾanā mina l-mušrikīna This is my path and way. Those who follow Islam and I preach about Islam and invite everyone to Islam and to worship Allah as the Only God with wisdom, intuition and insight. And Subhan Allah, and I am not of those who associate others with Him. )Muslims are also encouraged to say SubhanAllah 33 times after prayer, the prophet taught that it is one of the four praises that Allah likes Muslims to say continuously. The phrase is used by Arabic speaking followers of the Eastern Syriac Churches, Assyrian, Antiochian Orthodox and Chaldean churches.

Ancient Rome
–
In its many centuries of existence, the Roman state evolved from a monarchy to a classical republic and then to an increasingly autocratic empire. Through conquest and assimilation, it came to dominate the Mediterranean region and then Western Europe, Asia Minor, North Africa and it is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern government, law, politics, engineering, art, literature, architecture, technology, warfare, religion, language and society. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. By the end of the Republic, Rome had conquered the lands around the Mediterranean and beyond, its domain extended from the Atlantic to Arabia, the Roman Empire emerged with the end of the Republic and the dictatorship of Augustus Caesar. 721 years of Roman-Persian Wars started in 92 BC with their first war against Parthia and it would become the longest conflict in human history, and have major lasting effects and consequences for both empires. Under Trajan, the Empire reached its territorial peak, Republican mores and traditions started to decline during the imperial period, with civil wars becoming a prelude common to the rise of a new emperor. Splinter states, such as the Palmyrene Empire, would divide the Empire during the crisis of the 3rd century. Plagued by internal instability and attacked by various migrating peoples, the part of the empire broke up into independent kingdoms in the 5th century. This splintering is a landmark historians use to divide the ancient period of history from the pre-medieval Dark Ages of Europe. King Numitor was deposed from his throne by his brother, Amulius, while Numitors daughter, Rhea Silvia, because Rhea Silvia was raped and impregnated by Mars, the Roman god of war, the twins were considered half-divine. The new king, Amulius, feared Romulus and Remus would take back the throne, a she-wolf saved and raised them, and when they were old enough, they returned the throne of Alba Longa to Numitor. Romulus became the source of the citys name, in order to attract people to the city, Rome became a sanctuary for the indigent, exiled, and unwanted. This caused a problem for Rome, which had a large workforce but was bereft of women, Romulus traveled to the neighboring towns and tribes and attempted to secure marriage rights, but as Rome was so full of undesirables they all refused. Legend says that the Latins invited the Sabines to a festival and stole their unmarried maidens, leading to the integration of the Latins, after a long time in rough seas, they landed at the banks of the Tiber River. Not long after they landed, the men wanted to take to the sea again, one woman, named Roma, suggested that the women burn the ships out at sea to prevent them from leaving. At first, the men were angry with Roma, but they realized that they were in the ideal place to settle. They named the settlement after the woman who torched their ships, the Roman poet Virgil recounted this legend in his classical epic poem the Aeneid

Military recruitment
–
Military recruitment is recruitment for military positions, that is, the act of requesting people, usually male adults, to join a military voluntarily. Involuntary military recruitment is known as conscription, to facilitate this process, armed forces have established recruiting commands. Military recruitment can be considered part of science if analysed as part of military history. Acquiring large amounts of forces in a short period of time, especially voluntarily. Recent cross-cultural studies suggest that, throughout the world, the broad categories may be used to define recruitment appeals. They include war, economic motivation, education, family and friends, politics, prior to the outbreak of World War I, military recruitment in the US was conducted primarily by individual states. Upon entering the war, however, the government took an increased role. The increased emphasis on an effort was reflected in World War I recruitment methods. Peter A. Padilla and Mary Riege Laner define six basic appeals to these recruitment campaigns, patriotism, job/career/education, adventure/challenge, social status, travel, between 1915 and 1918, 42% of all army recruitment posters were themed primarily by patriotism. In the aftermath of World War II military recruitment shifted significantly, with no war calling men and women to duty, the United States refocused its recruitment efforts to present the military as a career option, and as a means of achieving a higher education. A majority - 55% - of all recruitment posters would serve this end, and though peacetime would not last, factors such as the move to an all-volunteer military would ultimately keep career-oriented recruitment efforts in place. The Defense Department turned to syndication as a recruiting aid from 1957-1960 with a filmed show, Country Style. On February 20,1970, the President’s Commission on an All-Volunteer Armed Force unanimously agreed that the United States would be best served by an all-volunteer military. In supporting this recommendation, the noted that recruitment efforts would have to be intensified. Much like the post-World War II era, these new campaigns put an emphasis on job opportunity. ”These new directives were to be combined with “an intensive recruiting effort. ”Finalized in mid-1973. In 1975 and 1976, military enlistments exceeded expectations, with over 365,000 men and women entering the military, indeed, recommendations made by the Presidents Commission continue to work in present-day recruitment efforts. Understanding the need for greater individual incentive, the US military has re-packaged the benefits of the GI Bill, though originally intended as compensation for service, the bill is now seen as a recruiting tool. Today, the GI Bill is no longer a reward for service rendered, while telephone prospecting is the most efficient, face to face prospecting is the most effective

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Plato
–
Plato was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, unlike nearly all of his philosophical contemporaries, Platos entire work is believed to have survived intact for over 2,400 years. Along with his teacher, Socrates, and his most famous student, Aristotle, Plato laid the foundations of Western philosophy. Alfred North Whitehead once noted, the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. In addition to being a figure for Western science, philosophy. Friedrich Nietzsche, amongst other scholars, called Christianity, Platonism for the people, Plato was the innovator of the written dialogue and dialectic forms in philosophy, which originate with him. He was not the first thinker or writer to whom the word “philosopher” should be applied, few other authors in the history of Western philosophy approximate him in depth and range, perhaps only Aristotle, Aquinas and Kant would be generally agreed to be of the same rank. Due to a lack of surviving accounts, little is known about Platos early life, the philosopher came from one of the wealthiest and most politically active families in Athens. Ancient sources describe him as a bright though modest boy who excelled in his studies, the exact time and place of Platos birth are unknown, but it is certain that he belonged to an aristocratic and influential family. Based on ancient sources, most modern scholars believe that he was born in Athens or Aegina between 429 and 423 BCE. According to a tradition, reported by Diogenes Laertius, Ariston traced his descent from the king of Athens, Codrus. Platos mother was Perictione, whose family boasted of a relationship with the famous Athenian lawmaker, besides Plato himself, Ariston and Perictione had three other children, these were two sons, Adeimantus and Glaucon, and a daughter Potone, the mother of Speusippus. The brothers Adeimantus and Glaucon are mentioned in the Republic as sons of Ariston, and presumably brothers of Plato, but in a scenario in the Memorabilia, Xenophon confused the issue by presenting a Glaucon much younger than Plato. Then, at twenty-eight, Hermodorus says, went to Euclides in Megara, as Debra Nails argues, The text itself gives no reason to infer that Plato left immediately for Megara and implies the very opposite. Thus, Nails dates Platos birth to 424/423, another legend related that, when Plato was an infant, bees settled on his lips while he was sleeping, an augury of the sweetness of style in which he would discourse about philosophy. Ariston appears to have died in Platos childhood, although the dating of his death is difficult. Perictione then married Pyrilampes, her mothers brother, who had served many times as an ambassador to the Persian court and was a friend of Pericles, Pyrilampes had a son from a previous marriage, Demus, who was famous for his beauty. Perictione gave birth to Pyrilampes second son, Antiphon, the half-brother of Plato and these and other references suggest a considerable amount of family pride and enable us to reconstruct Platos family tree

The School of Athens
–
The School of Athens is one of the most famous frescoes by the Italian Renaissance artist Raphael. It was painted between 1509 and 1511 as a part of Raphaels commission to decorate the rooms now known as the Stanze di Raffaello, the picture has long been seen as Raphaels masterpiece and the perfect embodiment of the classical spirit of the Renaissance. The School of Athens is one of a group of four main frescoes on the walls of the Stanza that depict distinct branches of knowledge, accordingly, the figures on the walls below exemplify Philosophy, Poetry, Theology, and Law. The traditional title is not Raphaels, indeed, Plato and Aristotle appear to be the central figures in the scene. However, all the philosophers depicted sought knowledge of first causes, many lived before Plato and Aristotle, and hardly a third were Athenians. The architecture contains Roman elements, but the general semi-circular setting having Plato, compounding the problem, Raphael had to invent a system of iconography to allude to various figures for whom there were no traditional visual types. For example, while the Socrates figure is immediately recognizable from Classical busts, aside from the identities of the figures depicted, many aspects of the fresco have been variously interpreted, but few such interpretations are unanimously accepted among scholars. The popular idea that the gestures of Plato and Aristotle are kinds of pointing is very likely. Aristotle, with his four-elements theory, held that all change on Earth was owing to motions of the heavens, in the painting Aristotle carries his Ethics, which he denied could be reduced to a mathematical science. Finally, according to Vasari, the scene includes Raphael himself, however, as Heinrich Wölfflin observed, it is quite wrong to attempt interpretations of the School of Athens as an esoteric treatise. The all-important thing was the motive which expressed a physical or spiritual state. An interpretation of the fresco relating to hidden symmetries of the figures, the identities of some of the philosophers in the picture, such as Plato or Aristotle, are certain. Beyond that, identifications of Raphaels figures have always been hypothetical, to complicate matters, beginning from Vasaris efforts, some have received multiple identifications, not only as ancients but also as figures contemporary with Raphael. Vasari mentions portraits of the young Federico II Gonzaga, Duke of Mantua, leaning over Bramante with his hands raised near the bottom right and he was writing over 40 years after the painting, and never knew Raphael, but no doubt reflects what was believed in his time. Many other popular identifications of portraits are very dubious, luitpold Dussler counts among those who can be identified with some certainty, Plato, Aristotle, Socrates, Pythagoras, Euclid, Ptolemy, Zoroaster, Raphael, Sodoma and Diogenes. Other identifications he holds to be more or less speculative, both figures hold modern, bound copies of their books in their left hands, while gesturing with their right. Plato holds Timaeus, Aristotle his Nicomachean Ethics, Plato is depicted as old, grey, wise-looking, and bare-foot. By contrast Aristotle, slightly ahead of him, is in manhood, handsome, well-shod and dressed with gold

Raphael
–
Raffaello Sanzio da Urbino, known as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form, ease of composition, together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period. Raphael was enormously productive, running a large workshop and, despite his death at 37. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, the best known work is The School of Athens in the Vatican Stanza della Segnatura. After his early years in Rome much of his work was executed by his workshop from his drawings and he was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking. Raphael was born in the small but artistically significant central Italian city of Urbino in the Marche region and his poem to Federico shows him as keen to show awareness of the most advanced North Italian painters, and Early Netherlandish artists as well. In the very court of Urbino he was probably more integrated into the central circle of the ruling family than most court painters. Under them, the court continued as a centre for literary culture, growing up in the circle of this small court gave Raphael the excellent manners and social skills stressed by Vasari. Castiglione moved to Urbino in 1504, when Raphael was no longer based there but frequently visited, Raphael mixed easily in the highest circles throughout his life, one of the factors that tended to give a misleading impression of effortlessness to his career. He did not receive a humanistic education however, it is unclear how easily he read Latin. His mother Màgia died in 1491 when Raphael was eight, followed on August 1,1494 by his father, Raphael was thus orphaned at eleven, his formal guardian became his only paternal uncle Bartolomeo, a priest, who subsequently engaged in litigation with his stepmother. He probably continued to live with his stepmother when not staying as an apprentice with a master and he had already shown talent, according to Vasari, who says that Raphael had been a great help to his father. A self-portrait drawing from his teenage years shows his precocity and his fathers workshop continued and, probably together with his stepmother, Raphael evidently played a part in managing it from a very early age. In Urbino, he came into contact with the works of Paolo Uccello, previously the court painter, and Luca Signorelli, according to Vasari, his father placed him in the workshop of the Umbrian master Pietro Perugino as an apprentice despite the tears of his mother. The evidence of an apprenticeship comes only from Vasari and another source, an alternative theory is that he received at least some training from Timoteo Viti, who acted as court painter in Urbino from 1495. An excess of resin in the varnish often causes cracking of areas of paint in the works of both masters, the Perugino workshop was active in both Perugia and Florence, perhaps maintaining two permanent branches. Raphael is described as a master, that is to say fully trained and his first documented work was the Baronci altarpiece for the church of Saint Nicholas of Tolentino in Città di Castello, a town halfway between Perugia and Urbino. Evangelista da Pian di Meleto, who had worked for his father, was named in the commission

The Creation of Adam
–
The Creation of Adam is a fresco painting by Michelangelo, which forms part of the Sistine Chapels ceiling, painted c. It illustrates the Biblical creation narrative from the Book of Genesis in which God breathes life into Adam, the fresco is part of a complex iconographic scheme and is chronologically the fourth in the series of panels depicting episodes from Genesis. The image of the hands of God and Adam has become iconic of humanity. The painting has been reproduced in countless imitations and parodies, leonardo da Vincis The Last Supper and Michelangelos Creation of Adam are the most replicated religious paintings of all time. In 1505, Michelangelo was invited back to Rome by the newly elected Pope Julius II and he was commissioned to build the Popes tomb, which was to include forty statues and be finished in five years. Under the patronage of the Pope, Michelangelo experienced constant interruptions to his work on the tomb in order to accomplish other tasks. Although Michelangelo worked on the tomb for 40 years, it was never finished to his satisfaction and it is located in the Church of S. Pietro in Vincoli in Rome and is most famous for the central figure of Moses, completed in 1516. Of the other statues intended for the tomb, two known as the Heroic Captive and the Dying Captive, are now in the Louvre, during the same period, Michelangelo painted the ceiling of the Sistine Chapel, which took approximately four years to complete. Michelangelo was originally commissioned to paint the Twelve Apostles on the pendentives that supported the ceiling. The work is part of a scheme of decoration within the chapel which represents much of the doctrine of the Catholic Church. The composition stretches over 500 square metres of ceiling, and contains over 300 figures, on the pendentives supporting the ceiling are painted twelve men and women who prophesied the coming of Jesus, seven prophets of Israel and five Sibyls, prophetic women of the Classical world. Among the most famous paintings on the ceiling are The Creation of Adam, Adam and Eve in the Garden of Eden, the Deluge, the Prophet Jeremiah and the Cumaean Sibyl. God is depicted as an elderly white-bearded man wrapped in a swirling cloak while Adam, another point is that Adams finger and Gods finger are not touching. It gives the impression that God, the giver of life, is reaching out to Adam who has yet to receive it, many hypotheses have been formulated regarding the identity and meaning of the figures around God. The Creation of Adam is generally thought to depict the excerpt God created man in His own image, in the image of God He created him. The inspiration for Michelangelos treatment of the subject may come from a hymn, Veni Creator Spiritus. Michelangelos main source of inspiration for his Adam in his Creation of Adam may have been a showing a nude Augustus Caesar riding sidesaddle on a Capricorn. This cameo is now at Alnwick Castle, Northumberland, the cameo used to belong to cardinal Domenico Grimani who lived in Rome while Michelangelo painted the ceiling

Extensor indicis muscle
–
In human anatomy, the extensor indicis is a narrow, elongated skeletal muscle in the deep layer of the dorsal forearm, placed medial to, and parallel with, the extensor pollicis longus. Its tendon goes to the finger, which it extends. It arises from the third of the dorsal part of the body of ulna. It runs through the fourth tendon compartment together with the extensor digitorum, opposite the head of the second metacarpal bone, it joins the ulnar side of the tendon of the extensor digitorum which belongs to the index finger. Like the extensor digiti minimi, the tendon of the extensor indicis runs, the extensor indicis lacks the juncturae tendinum interlinking the tendons of the extensor digitorum on the dorsal side of the hand. The extensor indicis proprius does not show much variation and it exists as a single tendon most of the time. The absence of the muscle was rarely reported with an incidence ranging from 0% to 4%, double tendons of the extensor indicis proprius was also reported. It is known that the extensor indicis proprius inserts to the finger on the ulnar side of the extensor digitorum. However, the insertion on the side of the common extensor digitorum infrequently seen. Split tendons of the muscle inserting on both ulnar and the side of the common extensor digitorum was also reported. The extensor indicis extends the index finger, and by its continued action assists in extending the wrist, because the index finger and little finger have separate extensors, these fingers can be moved more independently than the other fingers.

Index (typography)
–
The symbol ☞ is a punctuation mark, called an index, manicule or fist. Other names for the symbol include printers fist, bishops fist, digit, mutton-fist, hand, hand director, pointer, the symbol originates in scribal tradition of the medieval and Renaissance period, appearing in the margin of manuscripts to mark corrections or notes. Some were playful and elaborate, but others were as simple as two squiggly strokes suggesting the barest sketch of a hand and thus quick to draw. After the popularization of the printing press starting in the 1450s, early printers using a type representing the manicule included Mathias Huss and Johannes Schabeler in Lyons in their 1484 edition of Paulus Florentinus Breviarum totius juris canonici. In the modern period, the hand became more popular in publications, advertising. In modern printing, it was used as a typographical symbol marking notes. The American Dictionary of Printing and Bookmaking treats it as the seventh in the sequence of footnote markers. Sherman argues that as the symbols became standardized, they were no longer reflective of individuality in comparison to other writing, and this explains their diminished popularity. The typical use of the hand is as a bullet-like symbol to direct the reader’s attention to important text. It is used this way both by annotators and printers, even in the first few centuries of use, it can be seen used to draw attention to specific text, such as a title, inserted text, noteworthy passage, or sententiae. In some cases, flower marks and asterisks were used for similar purposes, less commonly, in earlier centuries the pointing hand acted as a section divider with a pilcrow as paragraph divider, or more rarely as the paragraph divider itself. Some encyclopedias use it in articles to cross-reference, as in ☞ other articles and it occasionally sees use in magazines and comic books to indicate to the reader that a story on the right-hand page continues onto the next. In linguistics, the symbol is used in optimality theory tableaux to identify the winner in a candidate set, American science fiction writer Kurt Vonnegut used the symbol as a form of margin on the first line of every paragraph in his novel Breakfast of Champions. The literary effect of this was to create separation between each paragraph, reinforcing the stream of consciousness style of the text. Thomas Pynchon parodies this punctuation mark in his novel Gravitys Rainbow by depicting a middle finger, rather than an index finger, an upward pointing hand is often used in the mouse cursor in graphical user interfaces to indicate an object that can be manipulated. The first is believed to be the Xerox Star, many web browsers use an upward pointing hand cursor to indicate a clickable hyperlink. CSS2.0 allows the property to be set to hand or pointer to intentionally change the mouse cursor to this symbol when hovering over an object. Many video games made in the 1980s and 90s, primarily text-based adventure games, V sign Charles Hasler, A Show of Hands, Typographica O. S.8, 4-11
