Tiger
–
The tiger is the largest cat species, most recognisable for their pattern of dark vertical stripes on reddish-orange fur with a lighter underside. The species is classified in the genus Panthera with the lion, leopard, jaguar, Tigers are apex predators, primarily preying on ungulates such as deer and bovids. They are territorial and generally solitary but social animals, often requiring large contiguous areas of habitat that support their prey requirements and this, coupled with the fact that they are indigenous to some of the more densely populated places on Earth, has caused significant conflicts with humans. Tigers once ranged widely across eastern Eurasia, from the Black Sea in the west, to the Indian Ocean in the south, today, they range from the Siberian taiga to open grasslands and tropical mangrove swamps. The remaining six tiger subspecies have been classified as endangered by the International Union for Conservation of Nature, a 2016 global census estimated the population of wild tigers at approximately 3,890 individuals. Major reasons for decline include habitat destruction, habitat fragmentation. The extent of area occupied by tigers is estimated at less than 1,184,911 km2, in 2016, wildlife conservation group at WWF declared that worlds count of wild tigers has risen for the first time in a century. Tigers are among the most recognisable and popular of the charismatic megafauna. They have featured prominently in ancient mythology and folklore, and continue to be depicted in modern films and they appear on many flags, coats of arms, and as mascots for sporting teams. The tiger is the animal of Bangladesh, India, Malaysia. In 1758, Linnaeus described the tiger in his work Systema Naturae, in 1929, the British taxonomist Reginald Innes Pocock subordinated the species under the genus Panthera using the scientific name Panthera tigris. The derivation from Greek pan- and ther may be folk etymology, the specific epithet, tigris, as well as the common name, tiger, come from the Middle English tigre and the Old English tigras, both used for the animal. These derive from the Old French tigre, itself a derivative of the Latin word tigris and the Greek word tigris. The original source may have been the Persian tigra meaning pointed or sharp, the tigers closest living relatives were previously thought to be the lion, leopard and jaguar, all of which are classified under the genus Panthera. The oldest remains of an extinct relative, called Panthera zdanskyi or the Longdan tiger, have been found in the Gansu province of northwestern China. This species is considered to be a taxon to the extant tiger and lived about 2 million years ago. It was smaller than the tiger, being the size of a jaguar. Despite being considered more primitive, the Longdan tiger was functionally and possibly ecologically similar to its modern cousin, as Panthera zdanskyi lived in northwestern China, that may have been where the tiger lineage originated

Animal
–
Animals are multicellular, eukaryotic organisms of the kingdom Animalia. The animal kingdom emerged as a clade within Apoikozoa as the group to the choanoflagellates. Animals are motile, meaning they can move spontaneously and independently at some point in their lives and their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs, they must ingest other organisms or their products for sustenance, most known animal phyla appeared in the fossil record as marine species during the Cambrian explosion, about 542 million years ago. Animals can be divided broadly into vertebrates and invertebrates, vertebrates have a backbone or spine, and amount to less than five percent of all described animal species. They include fish, amphibians, reptiles, birds and mammals, the remaining animals are the invertebrates, which lack a backbone. These include molluscs, arthropods, annelids, nematodes, flatworms, cnidarians, ctenophores, the study of animals is called zoology. The word animal comes from the Latin animalis, meaning having breath, the biological definition of the word refers to all members of the kingdom Animalia, encompassing creatures as diverse as sponges, jellyfish, insects, and humans. Aristotle divided the world between animals and plants, and this was followed by Carl Linnaeus, in the first hierarchical classification. In Linnaeuss original scheme, the animals were one of three kingdoms, divided into the classes of Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia. Since then the last four have all been subsumed into a single phylum, in 1874, Ernst Haeckel divided the animal kingdom into two subkingdoms, Metazoa and Protozoa. The protozoa were later moved to the kingdom Protista, leaving only the metazoa, thus Metazoa is now considered a synonym of Animalia. Animals have several characteristics that set apart from other living things. Animals are eukaryotic and multicellular, which separates them from bacteria and they are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls. All animals are motile, if only at life stages. In most animals, embryos pass through a stage, which is a characteristic exclusive to animals. With a few exceptions, most notably the sponges and Placozoa and these include muscles, which are able to contract and control locomotion, and nerve tissues, which send and process signals

Chinese zodiac
–
The Chinese zodiac is a classification scheme that assigns an animal and its reputed attributes to each year in a repeating 12-year cycle. The 12-year cycle is an approximation to the 11. 86-year orbital period of Jupiter, nevertheless, there are major differences, the Chinese 12-part cycle corresponds to years, rather than months. The Chinese zodiac is represented by 12 animals, whereas some of the signs in the Western zodiac are not animals, the animals of the Chinese zodiac are not associated with constellations spanned by the ecliptic plane. The zodiac traditionally begins with the sign of the Rat, the following are the twelve zodiac signs in order and their characteristics. It is a misconception that the animals assigned by year are the only signs. In fact, there are also animal signs assigned by month, by day, while a person might appear to be a Dragon because they were born in the year of the Dragon, they might also be a Snake internally, an Ox truly, and a Goat secretively. A conflict between a persons zodiac sign and how they live is known as tai sui or kai sui, within the Four Pillars, the year is the pillar representing information about the persons family background and society or relationship with their grandparents. The persons age can also be deduced from the sign of the person, the current sign of the year. For example, a person who is a Tiger is either 12,24,36 or 48 years old in 2010, in 2011, the year of the Rabbit, that person is one year older. The following table shows the 60-year cycle matched up to the Western calendar for the years 1924–2043, the sexagenary cycle begins at lichun about February 4 according to some astrological sources. Within the Four Pillars, the month is the pillar representing information about the parents or childhood. Many Chinese astrologers consider the month pillar to be the most important one in determining the circumstances of ones adult life, the 12 animals are also linked to traditional Chinese agricultural calendar, which runs alongside the better known lunar calendar. Instead of months, this calendar is divided into 24 two week segments known as Solar Terms, each animal is linked to two of these solar terms for a period similar to the Western month. Again unlike the cycle of the years, which begins with the Rat. Around summer days are longer than days, because it occurs differences of perihelion and aphelion. As each sign is linked to a month of the solar year, each of the elements is also linked to a season, and the element that shares a season with a sign is known as that signs fixed element. In other words, that element is believed to some of its characteristics to the sign concerned. The fixed element of each sign applies also to the year and hour signs and it is important to note that the fixed element is separate from the cycle of elements which interact with the signs in the 60-year cycle

Snake (zodiac)
–
The Snake is one of the 12-year cycle of animals which appear in the Chinese zodiac and related to the Chinese calendar, as well as in related East Asian zodiacal or calendrical systems. The Year of the Snake is associated with the Earthly Branch symbol 巳, according to one mythical legend, there is a reason for the order of the 12 animals in the 12-year cycle. The story goes that a race was held to cross a river. The same 12 animals are used to symbolize the cycle of hours in the day. The hour of the Snake is 9,00 to 11,00 a. m. the time when the sun warms up the earth, the month of the Snake is May 5 to June 5. In Chinese symbology, Snakes are regarded as intelligent, but with a tendency to be somewhat unscrupulous, the Snake is the 6th of the 12 signs and belongs to the Second Trine, together with the Ox and the Rooster, with which it is most compatible. Depictions of zodiacal Snakes either solo or in context with the other eleven zodiacal creatures shows how they have been imagined in the calendrical context.

Mathematics
–
Mathematics is the study of topics such as quantity, structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope, Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof, when mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry, rigorous arguments first appeared in Greek mathematics, most notably in Euclids Elements. Galileo Galilei said, The universe cannot be read until we have learned the language and it is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth, carl Friedrich Gauss referred to mathematics as the Queen of the Sciences. Benjamin Peirce called mathematics the science that draws necessary conclusions, David Hilbert said of mathematics, We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules, rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. Albert Einstein stated that as far as the laws of mathematics refer to reality, they are not certain, Mathematics is essential in many fields, including natural science, engineering, medicine, finance and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics, Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, the history of mathematics can be seen as an ever-increasing series of abstractions. The earliest uses of mathematics were in trading, land measurement, painting and weaving patterns, in Babylonian mathematics elementary arithmetic first appears in the archaeological record. Numeracy pre-dated writing and numeral systems have many and diverse. Between 600 and 300 BC the Ancient Greeks began a study of mathematics in its own right with Greek mathematics. Mathematics has since been extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today, the overwhelming majority of works in this ocean contain new mathematical theorems and their proofs. The word máthēma is derived from μανθάνω, while the modern Greek equivalent is μαθαίνω, in Greece, the word for mathematics came to have the narrower and more technical meaning mathematical study even in Classical times

Wu Xing
–
The Five Phases are Wood, Fire, Earth, Metal, and Water. This order of presentation is known as the generation sequence. In the order of mutual overcoming, they are Wood, Earth, Water, Fire, the system of five phases was used for describing interactions and relationships between phenomena. The system is used as a reference in some forms of complementary and alternative medicine. Xing of Wu Xing means moving, a planet is called a star in Chinese. Wu Xing originally refers to the five planets that create five dimensions of earth life. Wu Xing is also translated as Five Elements and this is used extensively by many including practitioners of Five Element acupuncture. This translation arose by analogy with the Western system of the four elements. By the same token, Mù is thought of as Tree rather than Wood, the word element is thus used within the context of Chinese medicine with a different meaning to its usual meaning. It should be recognized that the phase, although commonly preferred, is not perfect. Phase is a translation for the five seasons mentioned below. Manfred Porkert attempts to resolve this by using Evolutive Phase for 五行 Wǔ Xíng and Circuit Phase for 五運 Wǔ Yùn, some of the Mawangdui Silk Texts also present the Wu Xing as five virtues or types of activities. Within Chinese medicine texts the Wu Xing are also referred to as Wu Yun or a combination of the two characters these emphasise the correspondence of five elements to five seasons, another tradition refers to the Wǔ Xíng as Wǔ Dé, the Five Virtues. Wood parts Earth Earth dams Water Water extinguishes Fire Fire melts Metal Metal chops Wood This cycle might also be called controls, according to Wu Xing theory, the structure of the cosmos mirrors the five phases. Each phase has a series of associations with different aspects of nature. In the ancient Chinese form of known as Feng Shui practitioners all based their art. All of these phases are represented within the trigrams, associated with these phases are colors, seasons and shapes, all of which are interacting with each other. Based on a directional energy flow from one phase to the next
