120-533: The Huancavelica area features a rough geography with highly varied elevation, from 1,950 metres in the valleys to more than 5,000 metres on its snow-covered summits. These mountains contain metallic deposits . They consist of the western chain of the Andes , which includes the Chunta mountain range , formed by a series of hills, the most prominent of which are: Sitaq (5,328m), Wamanrasu (5,298m) and Altar (5,268m). Among

240-423: A time capsule . Although neither Voyager spacecraft is heading toward any particular star, Voyager 1 will pass within 1.6 light-years ' distance of the star Gliese 445 , currently in the constellation Camelopardalis , in about 40,000 years . Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space , but

360-468: A "bitter river" ( Oceanus ), with seven islands arranged around it so as to form a seven-pointed star. The accompanying text mentions seven outer regions beyond the encircling ocean. The descriptions of five of them have survived. In contrast to the Imago Mundi , an earlier Babylonian world map dating back to the 9th century BC depicted Babylon as being further north from the center of the world, though it

480-407: A civilization that encounters the record will be able to use the ratio of remaining uranium to the other elements to determine the age of the record. The records also had the inscription "To the makers of music – all worlds, all times" hand-etched on its surface. The inscription was located in the "takeout grooves", an area of the record between the label and playable surface. Since this was not in

600-402: A consequence of accessibility ." Geography is a branch of inquiry that focuses on spatial information on Earth. It is an extremely broad topic and can be broken down multiple ways. There have been several approaches to doing this spanning at least several centuries, including "four traditions of geography" and into distinct branches. The Four traditions of geography are often used to divide

720-418: A geographic information system). Remote sensing aids in land use, land cover (LULC) mapping, by helping to determine both what is naturally occurring on a piece of land and what human activities are taking place on it. Geostatistics deal with quantitative data analysis, specifically the application of a statistical methodology to the exploration of geographic phenomena. Geostatistics is used extensively in

840-551: A greeting by Sagan's six-year-old son, Nick ; other human sounds, like footsteps and laughter (Sagan's); the inspirational message Per aspera ad astra in Morse code ; and musical selections from different cultures and eras. The record also includes a printed message from U.S. president Jimmy Carter . The collection of images includes many photographs and diagrams both in black and white, and color. The first images are of scientific interest, showing mathematical and physical quantities,

960-606: A high level of information for Ptolemy to construct detailed atlases . He extended the work of Hipparchus , using a grid system on his maps and adopting a length of 56.5 miles for a degree. From the 3rd century onwards, Chinese methods of geographical study and writing of geographical literature became much more comprehensive than what was found in Europe at the time (until the 13th century). Chinese geographers such as Liu An , Pei Xiu , Jia Dan , Shen Kuo , Fan Chengda , Zhou Daguan , and Xu Xiake wrote important treatises, yet by

1080-493: A history, they also exist in space and have a geography. For something to exist in the realm of geography, it must be able to be described spatially. Thus, space is the most fundamental concept at the foundation of geography. The concept is so basic, that geographers often have difficulty defining exactly what it is. Absolute space is the exact site, or spatial coordinates, of objects, persons, places, or phenomena under investigation. We exist in space. Absolute space leads to

1200-480: A message aboard—a kind of time capsule , intended to communicate to extraterrestrials a story of the world of humans on Earth. This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University . The selection of content for

1320-565: A product with greater information than a two-dimensional image of places, names, and topography. This approach offers more inclusive strategies than more traditional cartographic approaches for connecting the complex layers that makeup places. Ethnographical research techniques are used by human geographers. In cultural geography , there is a tradition of employing qualitative research techniques, also used in anthropology and sociology. Participant observation and in-depth interviews provide human geographers with qualitative data. Geopoetics

1440-470: A single person from a single location. The European Age of Discovery during the 16th and the 17th centuries, where many new lands were discovered and accounts by European explorers such as Christopher Columbus , Marco Polo , and James Cook revived a desire for both accurate geographic detail and more solid theoretical foundations in Europe. In 1650, the first edition of the Geographia Generalis

1560-434: A structured or semi-structured approach during interviews involving specific questions or discussion points when utilized for research purposes. These questions are designed to extract focused information about the research topic while being flexible enough to allow participants to express their experiences and viewpoints, such as through open-ended questions. The concept of geography is present in all cultures, and therefore

1680-439: A system. The amount of time an individual, or group of people, spends in a place will often shape their attachment and perspective to that place. Time constrains the possible paths that can be taken through space, given a starting point, possible routes, and rate of travel. Visualizing time over space is challenging in terms of cartography, and includes Space-Prism, advanced 3D geovisualizations, and animated maps . Scale in

1800-417: A variety of fields, including hydrology , geology, petroleum exploration, weather analysis, urban planning , logistics, and epidemiology . The mathematical basis for geostatistics derives from cluster analysis , linear discriminant analysis and non-parametric statistical tests , and a variety of other subjects. Applications of geostatistics rely heavily on geographic information systems , particularly for

1920-671: A wedding song sung by a young girl from this region was included on the Golden Record carried on board the Voyager 1 and Voyager 2 probes. Buses run from Huancavelica to Huancayo and Lima by a paved road. There is another road that connects it with the city of Pisco in the coast. Buses depart from the bus station on the west side of the city. Huancavelica is serviced by a train which runs between it and Huancayo known as " el Tren Macho ". According to popular saying, this train "leaves when it wants and arrives when it can...". In 2009,

2040-713: Is also home to the University for Andean Development (Universidad para el Desarrollo Andino) located in Lircay, which is a city one hour from Huancavelica. There are other technical institutes like the Technological High Institute (Instituto Superior Tecnologico) and the Instituto Superior Pedagogico . The city has one hospital; the Hospital General , that serves the city and the nearby towns. Close to

2160-750: Is an interdisciplinary approach that combines geography and poetry to explore the interconnectedness between humans, space, place, and the environment. Geopoetics is employed as a mixed methods tool to explain the implications of geographic research. It is often employed to address and communicate the implications of complex topics, such as the anthropocene . Geographers employ interviews to gather data and acquire valuable understandings from individuals or groups regarding their encounters, outlooks, and opinions concerning spatial phenomena. Interviews can be carried out through various mediums, including face-to-face interactions, phone conversations, online platforms, or written exchanges. Geographers typically adopt

2280-436: Is an ongoing source of debate in geography and is unlikely to be resolved anytime soon. Several laws have been proposed, and Tobler's first law of geography is the most generally accepted in geography. Some have argued that geographic laws do not need to be numbered. The existence of a first invites a second, and many have proposed themselves as that. It has also been proposed that Tobler's first law of geography should be moved to

2400-414: Is concerned with the study of processes and patterns in the natural environment like the atmosphere , hydrosphere , biosphere , and geosphere . Technical geography is interested in studying and applying techniques and methods to store, process, analyze, visualize, and use spatial data. It is the newest of the branches, the most controversial, and often other terms are used in the literature to describe

2520-475: Is credited to Hipparchus . He employed a sexagesimal system that was derived from Babylonian mathematics . The meridians were subdivided into 360°, with each degree further subdivided into 60 ( minutes ). To measure the longitude at different locations on Earth, he suggested using eclipses to determine the relative difference in time. The extensive mapping by the Romans as they explored new lands would later provide

2640-469: Is impacted by all other locations on Earth. In one of Yi-Fu Tuan 's papers, he explains that in his view, geography is the study of Earth as a home for humanity, and thus place and the complex meaning behind the term is central to the discipline of geography. Time is usually thought to be within the domain of history , however, it is of significant concern in the discipline of geography. In physics, space and time are not separated, and are combined into

2760-417: Is not certain what that center was supposed to represent. The ideas of Anaximander (c. 610–545 BC): considered by later Greek writers to be the true founder of geography, come to us through fragments quoted by his successors. Anaximander is credited with the invention of the gnomon , the simple, yet efficient Greek instrument that allowed the early measurement of latitude . Thales is also credited with

2880-486: Is not their main preoccupation. Geographers study the Earth's spatial and temporal distribution of phenomena, processes, and features as well as the interaction of humans and their environment . Because space and place affect a variety of topics, such as economics, health, climate , plants, and animals, geography is highly interdisciplinary. The interdisciplinary nature of the geographical approach depends on an attentiveness to

3000-526: Is one of the broadest, is consistent with the naming convention of the other two branches, has been in use since the 1700s, and has been used by the UNESCO Encyclopedia of Life Support Systems to divide geography into themes. As academic fields increasingly specialize in their nature, technical geography has emerged as a branch of geography specializing in geographic methods and thought. The emergence of technical geography has brought new relevance to

[REDACTED] Media related to Huancavelica at Wikimedia Commons Geography Geography (from Ancient Greek γεωγραφία geōgraphía ; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth . Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities —not merely where objects are, but also how they have changed and come to be. While geography

3240-454: Is related to everything else, but near things are more related than distant things." As spatial interrelationships are key to this synoptic science, maps are a key tool. Classical cartography has been joined by a more modern approach to geographical analysis, computer-based geographic information systems (GIS). In their study, geographers use four interrelated approaches: Quantitative methods in geography became particularly influential in

3360-448: Is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science . Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" ( c.  276 BC  – c.  195/194 BC ). The first recorded use of

3480-430: Is spherical in shape, with the credit going either to Parmenides or Pythagoras . Anaxagoras was able to demonstrate that the profile of the Earth was circular by explaining eclipses . However, he still believed that the Earth was a flat disk, as did many of his contemporaries. One of the first estimates of the radius of the Earth was made by Eratosthenes . The first rigorous system of latitude and longitude lines

3600-484: Is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0.70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom . The drawing indicates that the record should be played from the outside in. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record—about an hour (more precisely, between 53 and 54 minutes). The information in

3720-536: Is the study of earth's seasons, climate , atmosphere , soil , streams, landforms, and oceans. Physical geographers will often work in identifying and monitoring the use of natural resources. Human geography (or anthropogeography) is a branch of geography that focuses on studying patterns and processes that shape human society. It encompasses the human, political, cultural , social, and economic aspects. In industry, human geographers often work in city planning, public health, or business analysis. Various approaches to

3840-562: The Earth radius was only 16.8 km less than the modern value of 6,356.7 km. In contrast to his predecessors, who measured the Earth's circumference by sighting the Sun simultaneously from two different locations, al-Biruni developed a new method of using trigonometric calculations based on the angle between a plain and mountain top, which yielded more accurate measurements of the Earth's circumference, and made it possible for it to be measured by

The influence of Immanuel Kant , Alexander von Humboldt , Carl Ritter , and Paul Vidal de la Blache can be seen as a major turning point in geography from philosophy to an academic subject. Geographers such as Richard Hartshorne and Joseph Kerski have regarded both Humboldt and Ritter as the founders of modern geography, as Humboldt and Ritter were

4320-584: The Solar System and its planets, DNA , and human anatomy and reproduction . Care was taken to include not only pictures of humanity, but also some of animals, insects, plants and landscapes. Images of humanity depict a broad range of cultures. These images show food, architecture, and humans in portraits as well as going about their day-to-day lives. Many pictures are annotated with one or more indications of scales of time, size, or mass. Some images contain indications of chemical composition . All measures used on

4440-638: The Spatial or Locational Tradition, the Man-Land or Human-Environment Interaction Tradition (sometimes referred to as Integrated geography ), the Area Studies or Regional Tradition, and the Earth Science Tradition. These concepts are broad sets of geography philosophies bound together within the discipline. They are one of many ways geographers organize the major sets of thoughts and philosophies within

4560-472: The built environment and how humans create, view, manage, and influence space. Physical geography examines the natural environment and how organisms , climate, soil , water, and landforms produce and interact. The difference between these approaches led to the development of integrated geography , which combines physical and human geography and concerns the interactions between the environment and humans. Technical geography involves studying and developing

4680-470: The first law of geography , "everything is related to everything else, but near things are more related than distant things." This law summarizes the first assumption geographers make about the world. The discipline of geography, especially physical geography, and geology have significant overlap. In the past, the two have often shared academic departments at universities, a point that has led to conflict over resources. Both disciplines do seek to understand

4800-607: The interpolation (estimate) of unmeasured points. Geographers are making notable contributions to the method of quantitative techniques. Qualitative methods in geography are descriptive rather than numerical or statistical in nature. They add context to concepts, and explore human concepts like beliefs and perspective that are difficult or impossible to quantify. Human geography is much more likely to employ qualitative methods than physical geography. Increasingly, technical geographers are attempting to employ GIS methods to qualitative datasets. Qualitative cartography employs many of

4920-452: The lithosphere , atmosphere , hydrosphere , and biosphere . Places do not exist in a vacuum and instead have complex spatial relationships with each other, and place is concerned how a location is situated in relation to all other locations. As a discipline then, the term place in geography includes all spatial phenomena occurring at a location, the diverse uses and meanings humans ascribe to that location, and how that location impacts and

5040-506: The quantitative revolution , and critical geography . The strong interdisciplinary links between geography and the sciences of geology and botany , as well as economics, sociology, and demographics , have also grown greatly, especially as a result of earth system science that seeks to understand the world in a holistic view. New concepts and philosophies have emerged from the rapid advancement of computers, quantitative methods, and interdisciplinary approaches. In 1970, Waldo Tobler proposed

5160-506: The quicksilver in the socavones (tunnels) was extremely difficult. Every day before the miners came down, a mass for the dead was celebrated. Due to the need of numerous hand-workers and the high rate of mortality, the Viceroy of Peru Francisco de Toledo resumed and improved the pre-Columbian mandatory service of the mita . The allotted concession were rectangular, about 67x33m. Miners were divided in carreteros and barreteros . Due to

Geology employs many of the tools and techniques of technical geographers, such as GIS and remote sensing to aid in geological mapping . However, geology includes research that goes beyond the spatial component, such as the chemical analysis of rocks and biogeochemistry . The discipline of History has significant overlap with geography, especially human geography. Like geology, history and geography have shared university departments. Geography provides

Suhrāb, a late tenth century Muslim geographer accompanied a book of geographical coordinates, with instructions for making a rectangular world map with equirectangular projection or cylindrical equidistant projection. Abu Rayhan Biruni (976–1048) first described a polar equi- azimuthal equidistant projection of the celestial sphere . He

5520-532: The "greatest jewel in the crown", they eliminated the need to ship mercury from Almadén . A miners guild , Gremio de Mineros, administered the mines from 1577 until 1782. Production stopped from 1813 through 1835. In 1915 E.E. Fernandini took over ownership. The area was the most prolific source of mercury in Spanish America , and as such was vital to the mining operations of the Spanish colonial era. Mercury

5640-695: The 17th century advanced ideas and methods of Western-style geography were adopted in China. During the Middle Ages , the fall of the Roman empire led to a shift in the evolution of geography from Europe to the Islamic world . Muslim geographers such as Muhammad al-Idrisi produced detailed world maps (such as Tabula Rogeriana ), while other geographers such as Yaqut al-Hamawi , Abu Rayhan Biruni , Ibn Battuta , and Ibn Khaldun provided detailed accounts of their journeys and

5760-473: The 9th century BCE in ancient Babylon . The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale. Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize

5880-470: The Earth for automatic retrieval by a computer in an accurate manner appropriate to the information's purpose. In addition to all of the other subdisciplines of geography, GIS specialists must understand computer science and database systems. GIS has revolutionized the field of cartography: nearly all mapmaking is now done with the assistance of some form of GIS software . The science of using GIS software and GIS techniques to represent, analyse, and predict

6000-493: The Earth most effectively and behavioural psychology to induce the readers of their maps to act on the information. They must learn geodesy and fairly advanced mathematics to understand how the shape of the Earth affects the distortion of map symbols projected onto a flat surface for viewing. It can be said, without much controversy, that cartography is the seed from which the larger field of geography grew. Geographic information systems (GIS) deal with storing information about

6120-529: The Earth's land surface , ocean, and atmosphere, because it: (a) supplies objective information at a variety of spatial scales (local to global), (b) provides a synoptic view of the area of interest, (c) allows access to distant and inaccessible sites, (d) provides spectral information outside the visible portion of the electromagnetic spectrum , and (e) facilitates studies of how features/areas change over time. Remotely sensed data may be analyzed independently or in conjunction with other digital data layers (e.g., in

6240-424: The Earth's surface, the activity and use that occurs, has occurred, and will occur at the coordinates, and the meaning ascribed to the space by human individuals and groups. This can be extraordinarily complex, as different spaces may have different uses at different times and mean different things to different people. In physical geography, a place includes all of the physical phenomena that occur in space, including

To celebrate the 40th anniversary of the record, Ozma Records launched a Kickstarter project to release the record contents in LP format as part of a box set also containing a hardcover book, turntable slipmat, and art print. The Kickstarter was successfully funded with over $ 1.4 million raised. Ozma Records then produced another edition of

6600-507: The art, science, and technology of making maps. Cartographers study the Earth's surface representation with abstract symbols (map making). Although other subdisciplines of geography rely on maps for presenting their analyses, the actual making of maps is abstract enough to be regarded separately. Cartography has grown from a collection of drafting techniques into an actual science. Cartographers must learn cognitive psychology and ergonomics to understand which symbols convey information about

6720-454: The book expanded on these key concepts by adding "Environmental systems," "Social Systems," "Nature," " Globalization ," "Development," and "Risk," demonstrating how challenging narrowing the field can be. Another approach used extensively in teaching geography are the Five themes of geography established by "Guidelines for Geographic Education: Elementary and Secondary Schools," published jointly by

6840-406: The broad discipline of geography by serving as a set of unique methods for managing the interdisciplinary nature of the phenomena under investigation. While human and physical geographers use the techniques employed by technical geographers, technical geography is more concerned with the fundamental spatial concepts and technologies than the nature of the data. It is therefore closely associated with

6960-408: The case of Mars), its features, and phenomena that take place on it. For something to fall into the domain of geography, it generally needs some sort of spatial component that can be placed on a map , such as coordinates , place names, or addresses . This has led to geography being associated with cartography and place names. Although many geographers are trained in toponymy and cartology, this

Another important site is the former Santa Barbara mine , located about three km. from the city on an ancient road that was famous during colonial times for the extraction of mercury. The main sporting stadium is the IPD Stadium of Huancavelica. At 3,676 meters above sea level, it

7200-438: The concept of spacetime . Geography is subject to the laws of physics, and in studying things that occur in space, time must be considered. Time in geography is more than just the historical record of events that occurred at various discrete coordinates; but also includes modeling the dynamic movement of people, organisms, and things through space. Time facilitates movement through space, ultimately allowing things to flow through

7440-405: The context of a map is the ratio between a distance measured on the map and the corresponding distance as measured on the ground. This concept is fundamental to the discipline of geography, not just cartography, in that phenomena being investigated appear different depending on the scale used. Scale is the frame that geographers use to measure space, and ultimately to understand a place. During

Geography is an extremely broad field. Because of this, many view the various definitions of geography proposed over the decades as inadequate. To address this, William D. Pattison proposed the concept of the "Four traditions of Geography" in 1964. These traditions are

There are several other terms, often used interchangeably with technical geography to subdivide the discipline, including "techniques of geographic analysis," "Geographic Information Technology," "Geography method's and techniques," " Geographic Information Science ," " geoinformatics ," " geomatics ," and "information geography". There are subtle differences to each concept and term; however, technical geography

8040-458: The discipline of geography is normally concerned with the Earth, the term can also be informally used to describe the study of other worlds, such as the planets of the Solar System and even beyond. The study of systems larger than the Earth itself usually forms part of Astronomy or Cosmology . The study of other planets is usually called planetary science . Alternative terms such as areography (geography of Mars) have been employed to describe

8160-489: The discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography , remote sensing , interviews , and surveying . Geography is a systematic study of the Earth (other celestial bodies are specified, such as "geography of Mars", or given another name, such as areography in

8280-552: The discipline. In another approach to the abovementioned four traditions, geography is organized into applied branches. The UNESCO Encyclopedia of Life Support Systems organizes geography into the three categories of human geography , physical geography , and technical geography . Some publications limit the number of branches to physical and human, describing them as the principal branches. Geographers rarely focus on just one of these topics, often using one as their primary focus and then incorporating data and methods from

8640-407: The emerging category. These branches use similar geographic philosophies, concepts, and tools and often overlap significantly. Physical geography (or physiography) focuses on geography as an Earth science . It aims to understand the physical problems and the issues of lithosphere , hydrosphere , atmosphere , pedosphere , and global flora and fauna patterns ( biosphere ). Physical geography

8760-514: The first to establish geography as an independent scientific discipline. Over the past two centuries, the advancements in technology with computers have led to the development of geomatics and new practices such as participant observation and geostatistics being incorporated into geography's portfolio of tools. In the West during the 20th century, the discipline of geography went through four major phases: environmental determinism , regional geography ,

8880-496: The geography of the regions they visited. Turkish geographer Mahmud al-Kashgari drew a world map on a linguistic basis, and later so did Piri Reis ( Piri Reis map ). Further, Islamic scholars translated and interpreted the earlier works of the Romans and the Greeks and established the House of Wisdom in Baghdad for this purpose. Abū Zayd al-Balkhī , originally from Balkh , founded

9000-449: The heights of mountains, depths of the valleys , and expanse of the horizon . He also discussed human geography and the planetary habitability of the Earth. He also calculated the latitude of Kath, Khwarezm , using the maximum altitude of the Sun, and solved a complex geodesic equation to accurately compute the Earth's circumference , which was close to modern values of the Earth's circumference. His estimate of 6,339.9 km for

Of the eleven instruments carried on Voyager 1 , four are still operational and continue to send back data. It is expected that at least one science instrument will remain operational through 2025 and that engineering data could be transmitted for several more years afterward. Most of

9240-589: The history of the discipline is a series of competing narratives, with concepts emerging at various points across space and time. The oldest known world maps date back to ancient Babylon from the 9th century BC. The best known Babylonian world map, however, is the Imago Mundi of 600 BC. The map as reconstructed by Eckhard Unger shows Babylon on the Euphrates , surrounded by a circular landmass showing Assyria , Urartu , and several cities, in turn surrounded by

Mercury, lead, and arsenic contamination owing to centuries of quicksilver mining in the city's surrounding expose approximately 19,000 of Huancavelica's residents to severe health threats. Exposure to these toxics has been linked to neuropsychological damage, kidney damage, fertility problems, and cancer, amongst others. Pregnant mothers, foetuses, and children are most at risk of health implications from mercury exposure. The city has monuments from

9480-415: The images used on the record (reproduced in black and white), together with information about its compilation, can be found in the 1978 book Murmurs of Earth: The Voyager Interstellar Record by Carl Sagan , F. D. Drake , Ann Druyan , Timothy Ferris , Jon Lomberg , and Linda Salzman . A CD-ROM version was issued by Warner New Media in 1992. Author Ann Druyan, who later married Carl Sagan, wrote about

9600-480: The launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet." The Voyager 1 probe is currently the farthest human-made object from Earth . Both Voyager 1 and Voyager 2 have reached interstellar space, the region between stars where the galactic plasma is present. Like their predecessors Pioneer 10 and 11 , which featured a simple plaque , both Voyager 1 and Voyager 2 were launched by NASA with

9720-402: The laws of nature and to mark their influences upon man. This is 'a description of the world'—that is Geography. In a word, Geography is a Science—a thing not of mere names but of argument and reason, of cause and effect. Geography as a discipline can be split broadly into three main branches: human geography , physical geography , and technical geography . Human geography largely focuses on

9840-472: The line between the break-of-gauge at Huancayo to Huancavelica was being converted from 914 mm ( 3 ft ) gauge to 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) gauge. By October 2010 it was finished and it is now in service. Huancavelica is home of the local university, the National University of Huancavelica , which has branches in other cities in the region. The region

9960-459: The lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the Solar System with respect to 14 pulsars , whose precise periods are given. The drawing containing two circles in the lower right-hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that

10080-452: The nudity on the Pioneer plaque (line drawings of a naked man and woman), the agency chose not to allow Sagan and his colleagues to include a photograph of a nude man and woman on the record. Instead, only a silhouette of the couple was included. However, the record does contain "Diagram of vertebrate evolution", by Jon Lomberg , with drawings of an anatomically correct naked male and naked female, showing external organs. The person waving on

10200-653: The original specifications, the record was initially rejected, to be replaced with a blank disc. Sagan later convinced the administrator to include the record as is. Voyager 1 was launched in 1977, passed the orbit of Pluto in 1990, and left the Solar System (in the sense of passing the termination shock ) in November 2004. It is now in the Kuiper belt . In about 40,000 years, it and Voyager 2 will each come to within about 1.8 light-years of two separate stars: Voyager 1 will have approached star Gliese 445 , located in

10320-414: The other branches. Often, geographers are asked to describe what they do by individuals outside the discipline and are likely to identify closely with a specific branch, or sub-branch when describing themselves to lay people. Human geography studies people and their communities, cultures, economies, and environmental interactions by studying their relations with and across space and place. Physical geography

10440-699: The pictures are defined in the first few images using physical references that are likely to be consistent anywhere in the universe . The musical selection is also varied, featuring works by composers such as J.S. Bach (interpreted by Glenn Gould ), Mozart , Beethoven (played by the Budapest String Quartet ), and Stravinsky . The disc also includes music by Guan Pinghu , Blind Willie Johnson , Chuck Berry , Kesarbai Kerkar , Valya Balkanska , and electronic composer Laurie Spiegel , as well as Azerbaijani folk music ( Mugham ) by oboe player Kamil Jalilov . The inclusion of Berry's " Johnny B. Goode "

10560-402: The prediction of eclipses. The foundations of geography can be traced to ancient cultures, such as the ancient, medieval, and early modern Chinese . The Greeks , who were the first to explore geography as both art and science, achieved this through Cartography , Philosophy , and Literature , or through Mathematics . There is some debate about who was the first person to assert that the Earth

10680-457: The quantitative revolution, geography shifted to an empirical law-making ( nomothetic ) approach. Several laws of geography have been proposed since then, most notably by Waldo Tobler and can be viewed as a product of the quantitative revolution. In general, some dispute the entire concept of laws in geography and the social sciences. These criticisms have been addressed by Tobler and others, such as Michael Frank Goodchild . However, this

10800-453: The record to permit the recipients to verify that they are decoding the signals correctly. A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction. Color images were represented by three images in sequence, one each for red, green, and blue components of the image. A color image of the spectrum of the sun was included for calibration purposes. The drawing in

10920-485: The record took almost a year. Sagan and his associates assembled 116 images (one used for calibration) and a variety of natural sounds, such as those made by surf, wind, thunder and animals (including the songs of birds and whales ). To this they added audio content to represent humanity: spoken greetings in 55 ancient and modern languages, including a spoken greeting in English by U.N. Secretary-General Kurt Waldheim and

11040-415: The records were plated they were mounted in aluminum containers and delivered to JPL. The record is a copper disk 12 inches (30 cm) in diameter plated first with nickel and then gold. The record's cover is aluminum and electroplated upon it is an ultra-pure sample of the isotope uranium-238 . Uranium-238 has a half-life of 4.468 billion years. It is possible (e.g., via mass spectrometry ) that

11160-473: The relationship between physical and human phenomena and their spatial patterns. Names of places...are not geography...To know by heart a whole gazetteer full of them would not, in itself, constitute anyone a geographer. Geography has higher aims than this: it seeks to classify phenomena (alike of the natural and of the political world, in so far as it treats of the latter), to compare, to generalize, to ascend from effects to causes, and, in doing so, to trace out

11280-774: The rivers of the region there are the Mantaro , the Pampas, the Huarpa and the Churcampa. The Mantaro River penetrates Huancavelica, forming Tayacaja's Peninsula. Another river that shapes the relief is the Pampas River which is born in the lakes of the high mountains of Huancavelica, Chuqlluqucha and Urququcha . The principal ore mineral is cinnabar , which occurs within the Cretaceous Gran Farallón sandstones , and fractures found in

11400-438: The same software and techniques as quantitative cartography. It may be employed to inform on map practices, or to visualize perspectives and ideas that are not strictly quantitative in nature. An example of a form of qualitative cartography is a Chorochromatic map of nominal data, such as land cover or dominant language group in an area. Another example is a deep map , or maps that combine geography and storytelling to produce

11520-533: The second and replaced with another. A few of the proposed laws of geography are below: Additionally, several variations or amendments to these laws exist within the literature, although not as well supported. For example, one paper proposed an amended version of Tobler's first law of geography, referred to in the text as the Tobler–von Thünen law , which states: "Everything is related to everything else, but near things are more related than distant things, as

11640-529: The song is cited as one of the legal challenges faced by the team compiling the Voyager Golden Record. In the book, Sagan said that the Beatles favoured the idea, but "[they] did not own the copyright, and the legal status of the piece seemed too murky to risk." When asked about the obstacle presented by EMI with regard to "Here Comes the Sun", despite the artists' wishes, Ann Druyan said in 2015: "Yeah, that

11760-471: The sounds of humpbacked whales from the 1970 album by Roger Payne , Songs of the Humpback Whale . The Golden Record also carries an hour-long recording of the brainwaves of Ann Druyan. During the recording of the brainwaves, Druyan thought of many topics, including Earth's history, civilizations and the problems they face, and what it was like to fall in love. After NASA had received criticism over

11880-445: The spatial context within which historical events unfold. The physical geographic features of a region, such as its landforms, climate, and resources, shape human settlements, trade routes, and economic activities, which in turn influence the course of historical events. Thus, a historian must have a strong foundation in geography. Historians employ the techniques of technical geographers to create historical atlases and maps. While

12000-675: The spatial relationships is called geographic information science (GISc). Remote sensing is the art, science, and technology of obtaining information about Earth's features from measurements made at a distance. Remotely sensed data can be either passive, such as traditional photography , or active, such as LiDAR . A variety of platforms can be used for remote sensing, including satellite imagery , aerial photography (including consumer drones), and data obtained from hand-held sensors. Products from remote sensing include Digital elevation model and cartographic base maps. Geographers increasingly use remotely sensed data to obtain information about

12120-534: The spatial tradition of geography while being applied to the other two major branches. A technical geographer might work as a GIS analyst, a GIS developer working to make new software tools, or create general reference maps incorporating human and natural features. All geographic research and analysis start with asking the question "where," followed by "why there." Geographers start with the fundamental assumption set forth in Tobler's first law of geography , that "everything

12240-538: The stars. At the termination shock, the solar wind slows abruptly from its average speed of 300–700 km/s (670,000–1,570,000 mph) and becomes denser and hotter. In March 2012, Voyager 1 was over 17.9 billion km from the Sun and traveling at a speed of 3.6 AU per year (approximately 61,000 km/h (38,000 mph)), while Voyager 2 was over 14.7 billion km away and moving at about 3.3 AU per year (approximately 56,000 km/h (35,000 mph)). On September 12, 2013, NASA announced that Voyager 1 had left

12360-403: The study of human geography have also arisen through time and include: Technical geography concerns studying and developing tools, techniques, and statistical methods employed to collect, analyze, use, and understand spatial data. Technical geography is the most recently recognized, and controversial, of the branches. Its use dates back to 1749, when a book published by Edward Cave organized

12480-502: The study of other celestial objects. Ultimately, geography may be considered a subdiscipline within planetary science. Voyager Golden Record The Voyager Golden Records are two identical phonograph records which were included aboard the two Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them. The records are

12600-534: The three-disc LP vinyl record box set that also includes the audio content of the Golden Record, softcover book containing the images encoded on the record, images sent back by Voyager , commentary from Ferris, art print, turntable slipmat, and a collector's box. This edition was released in February 2018 along with a 2xCD-Book edition. In January 2018, Ozma Records' "Voyager Golden Record; 40th Anniversary Edition" won

12720-756: The time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for the time given on the cover and in the decoded pictures. Blank records were provided by the Pyral S.A. of Créteil , France. CBS Records contracted the JVC Cutting Center in Boulder, Colorado to cut the lacquer masters which were then sent to the James G. Lee record-processing center in Gardena, California to cut and gold-plate eight Voyager records. After

12840-557: The times when geography became recognized as a discrete academic discipline , and became part of a typical university curriculum in Europe (especially Paris and Berlin ). The development of many geographic societies also occurred during the 19th century, with the foundations of the Société de Géographie in 1821, the Royal Geographical Society in 1830, Russian Geographical Society in 1845, American Geographical Society in 1851,

12960-489: The tools and techniques used by geographers, such as remote sensing, cartography, and geographic information system. Narrowing down geography to a few key concepts is extremely challenging, and subject to tremendous debate within the discipline. In one attempt, the 1st edition of the book "Key Concepts in Geography" broke down this into chapters focusing on "Space," "Place," "Time," "Scale," and "Landscape." The 2nd edition of

13080-442: The upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of a picture. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to analog television (in which the picture is a series of horizontal lines). Picture lines 1, 2 and 3 are noted in binary numbers, and

13200-439: The viceroy thought that Spain could, if necessary, dispense with the silver from Potosí, but it could not dispense with the mercury from Huancavelica. In the modern times, due to different political and economical events, the city went through a period of decades of lack of progress from the rest of the country. Now, this situation appears to change due to the attention of the recent government administrations. A 1977 recording of

13320-401: The view of the world as a photograph, with everything frozen in place when the coordinates were recorded. Today, geographers are trained to recognize the world as a dynamic space where all processes interact and take place, rather than a static image on a map. Place is one of the most complex and important terms in geography. In human geography, place is the synthesis of the coordinates on

13440-408: The word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography ) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to

13560-483: Was controversial, with some claiming that rock music was "adolescent", to which Sagan replied, "There are a lot of adolescents on the planet." The selection of music for the record was completed by a team composed of Carl Sagan as project director, Linda Salzman Sagan , Frank Drake , Alan Lomax , Ann Druyan as creative director, artist Jon Lomberg , ethnomusicologist Robert E. Brown , Timothy Ferris as producer, and Jimmy Iovine as sound engineer. It also included

13680-597: Was finding the latitude and longitude of a geographic location. While the problem of latitude was solved long ago, but that of longitude remained; agreeing on what zero meridians should be was only part of the problem. It was left to John Harrison to solve it by inventing the chronometer H-4 in 1760, and later in 1884 for the International Meridian Conference to adopt by convention the Greenwich meridian as zero meridians. The 18th and 19th centuries were

13800-464: Was necessary to extract silver from the ores produced in the silver mines of Peru, as well as those of Potosí in Upper Peru (now Bolivia ), using amalgamation processes such as the patio process or pan amalgamation . Mercury was so essential that mercury consumption was the basis upon which the tax on precious metals , known as the quinto real ("royal fifth"), was levied. The extraction of

13920-461: Was one of those cases of having to see the tragedy of our planet. Here's a chance to send a piece of music into the distant future and distant time, and to give it this kind of immortality, and they're worried about money ... we got this telegram [from EMI] saying that it will be $ 50,000 per record for two records, and the entire Voyager record cost $ 18,000 to produce." However, this was denied in 2017 by Timothy Ferris ; in his recollection, "Here Comes

14040-671: Was produced from 1571 until 1790, amounting to more than 1,400,000 flasks. At the time of Spanish conquest, Huancavelica was known as the Wankawillka region or "sacred stone". The city itself was established on August 5, 1572 by viceroy Francisco de Toledo . The community has expanded throughout the region. The deposits of Huancavelica were disclosed in 1564, or 1566, by the Indian Nahuincopa to his master Jerónimo Luis de Cabrera. The Spanish Crown appropriated them in 1570 and operated them until Peruvian independence in 1821. Considered

14160-551: Was published by Bernhardus Varenius , which was later edited and republished by others including Isaac Newton . This textbook sought to integrate new scientific discoveries and principles into classical geography and approach the discipline like the other sciences emerging, and is seen by some as the division between ancient and modern geography in the West. The Geographia Generalis contained both theoretical background and practical applications related to ship navigation. The remaining problem facing both explorers and geographers

14280-513: Was regarded as the most skilled when it came to mapping cities and measuring the distances between them, which he did for many cities in the Middle East and the Indian subcontinent . He often combined astronomical readings and mathematical equations to develop methods of pin-pointing locations by recording degrees of latitude and longitude . He also developed similar techniques when it came to measuring

14400-480: Was still early in his career as a music producer, served as sound engineer for the project at the recommendation of John Lennon , who was contacted to contribute but was unable to take part. Sagan's team wanted to include the Beatles 1969 song " Here Comes the Sun " on the record, but the record company EMI , which held the copyrights, declined. In the 1978 book Murmurs of Earth , the failure to secure permission for
