Timeline Of Hadrosaur Research
A timeline is a display of a list of events in chronological order. It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. This timescale is dependent on the events in the timeline. A timeline of evolution can be over millions of years, whereas a timeline for the day of the September 11 attacks can take place over minutes, and that of an explosion over milliseconds. While many timelines use a linear timescale—especially where very large or small timespans are relevant -- logarithmic timelines entail a logarithmic scale of time; some "hurry up and wait" chronologies are depicted with zoom lens metaphors. History Time and space, particularly the line, are intertwined concepts in human thought. The line is ubiquitous in clocks in t ...

A New Chart Of History Color
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish i ...

Regnal List
A regnal list or king list is, at its simplest, a list of successive monarchs. Some regnal lists may give the relationship between successive monarchs (e.g., son, brother), the length of reign of each monarch or annotations on important reigns. The list may be divided into dynasties marked off by headings. As a distinct genre, the regnal list originates in the ancient Near East. Its purpose was not originally chronological. It originally served to demonstrate the antiquity and legitimacy of the monarchy, but it became an important device for structuring historical narratives (as in Herodotus) and thus a chronological aid. In antiquity, regnal lists were kept in Sumer, Egypt, Israel, Assyria and Babylonia. King lists have made it into sacred religious texts, such as the ''Puranas'' and the Hebrew Bible, which contains an Edomite king list. Regnal lists were kept in early medieval Ireland, Pictland and Anglo-Saxon England. The historian David Dumville regarded them as more rel ...

Thematic Map
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population. In this, they contrast with general reference maps, which focus on the location (more than the properties) of a diverse set of physical features, such as rivers, roads, and buildings. Alternative names have been suggested for this class, such as ''special-subject'' or ''special-purpose maps'', ''statistical maps'', or ''distribution maps'', but these have generally fallen out of common usage. Thematic mapping is closely allied with the field of Geovisualization. Several types of thematic maps have been invented, starting in the 18th and 19th centuries, as large amounts of statistical data began to be collected and published, such as national censuses. These types, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Joseph Minard
Charles Joseph Minard (; ; 27 March 1781 – 24 October 1870) was a French civil engineer recognized for his significant contribution in the field of information graphics in civil engineering and statistics. Minard was, among other things, noted for his representation of numerical data on geographic maps, especially his flow maps. Early life Minard was born in Dijon in the Saint Michel parish. He was the son of Pierre Etienne Minard and Bénigne Boiteux. His father was a clerk of the court and an officer of the secondary school. Minard was baptized at Saint Michel on the day of his birth. From Posted by Edward Tufte. He was very bright and his father encouraged him to study at an early age. At age four he learned to read and write, and when he was six his father enrolled him in an elementary course in anatomy. He completed his fourth year of study at the secondary school at Dijon early, and then applied himself to studying Latin, literature, and physical and math sciences. At ...

Jacques Barbeu-Dubourg
Jacques Barbeu-Dubourg (12 February 1709 – 14 December 1779) was a French physician, botanist, writer, translator and publisher known for translating Benjamin Franklin's work into French and for inventing a gentlemen's umbrella fitted with a lightning conductor. He designed a method of histographic visualizations which he called the ''Carte chronographique''. Life He first embarked on theological studies, but abandoned this to devote his life to science. He studied medicine in Paris and obtained a doctorate in 1748. He was a keen follower of the work of Benjamin Franklin, and they maintained a regular friendly correspondence. He translated some of Franklin's early experimental work into French in 1762 and published it in ''Gazette d'Epidaure'', his medical journal. He went on to publish his French translation of Franklin's ''Observations and Experiments'' in 1773. Barbeu-Dubourg's "umbrella-lightning rod", an umbrella fitted with a tall spike and trailing chain, was designed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrochronology
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronophotography
Chronophotography is a photographic technique from the Victorian era which captures a number of phases of movements. The best known chronophotography works were mostly intended for the scientific study of locomotion, to discover practical information for animal handlers and/or as reference material for artists. Although many results were not intended to be exhibited as moving pictures, there is much overlap with the more or less simultaneous quest to register and exhibit photographic motion pictures. Definition Chronophotography is defined as "a set of photographs of a moving object, taken for the purpose of recording and exhibiting successive phases of motion". The term ''chronophotography'' was coined by French physiologist Étienne-Jules Marey to describe photographs of movement from which measurements could be taken and motion could be studied. It is derived from the Greek word χρόνος '' chrónos'' ("time") combined with '' photography''.The J. Paul Getty Museum (1 ...

Positivism
Positivism is an empiricist philosophical theory that holds that all genuine knowledge is either true by definition or positive—meaning ''a posteriori'' facts derived by reason and logic from sensory experience.John J. Macionis, Linda M. Gerber, ''Sociology'', Seventh Canadian Edition, Pearson Canada Other ways of knowing, such as theology, metaphysics, intuition, or introspection, are rejected or considered meaningless. Although the positivist approach has been a recurrent theme in the history of western thought, modern positivism was first articulated in the early 19th century by Auguste Comte.. His school of sociological positivism holds that society, like the physical world, operates according to general laws. After Comte, positivist schools arose in logic, psychology, economics, historiography, and other fields of thought. Generally, positivists attempted to introduce scientific methods to their respective fields. Since the turn of the 20th century, positivism ...

A Chart Of Biography
In 1765, 18th-century British polymath Joseph Priestley published ''A Chart of Biography'' and its accompanying prose description as a supplement to his '' Lectures on History and General Policy''. Priestley believed that the chart and '' A New Chart of History'' (1769) would allow students to "trace out distinctly the dependence of events to distribute them into such periods and divisions as shall lay the whole claim of past transactions in a just and orderly manner." The ''Chart of Biography'' covers a vast timespan, from 1200 BC to 1800 AD, and includes two thousand names. Priestley organized his list into six categories: Statesman and Warriors; Divines and Metaphysicians; Mathematicians and Physicians (natural philosophers were placed here); Poets and Artists; Orators and Critics (prose fiction authors were placed here); and Historians and Antiquarians (lawyers were placed here). Priestley's "principle of selection" was fame, not merit; therefore, as he mentions, the chart i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Priestley
Joseph Priestley (; 24 March 1733 – 6 February 1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, and liberal political theorist. He published over 150 works, and conducted experiments in electricity and other areas of science. He was a close friend of, and worked in close association with Benjamin Franklin involving electricity experiments. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. ...

Gerardus Mercator
Gerardus Mercator (; 5 March 1512 – 2 December 1594) was a 16th-century geographer, cosmographer and cartographer from the County of Flanders. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts. Mercator was a highly influential pioneer in the history of cartography. Monmonier, Mark: ''Rhumb Lines and Map Wars: A Social History of the Mercator Projection''.

Renaissance
The Renaissance ( , ) , from , with the same meanings. is a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries, characterized by an effort to revive and surpass ideas and achievements of classical antiquity. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages. However, the beginnings of the period – the early Renaissance of the 15th century and the Italian Proto-Renaissance from around 1250 or 1300 – overlap considerably with the Late Middle Ages, conventi ...
