Exploring Two Old Mining Cabins and Mining Prospects
Awesome. Beautiful. Tremendous. A rare find. Those are some of the words and phrases I'd use to describe the remote, historic miner's cabin I spent a couple days at out in the desert. While exploring the hills and mountains around the cabin, I found another historic miner's cabin as well as several small prospects and mines. Gold and silver seemed to be the commodities that were mined in the area back in the early 1900s. The cabins are definitely historic relics leftover from an almost-forgotten time in our mining history.

Ancient uranium mining
Support the channel https://www.paypal.me/philippdruzhinin What you call a 100% percent of worlds uranium is really less than 1 % of what's left of ancient mining of 16-17 century. This video continues the topic of Ancient uranium mining and connection to the pillars of wethering and buttes. There are whole bunch of those mining sites of Atlanteans. If the giants were really large, they did large scale mining and left behind the small stuff -- for us, the small people who think they have really found something "big." So many questions about the new real science, these new things keep bumping into one another, but I think they may be all about "layers" of history. Giants, mining, flood disasters, wars (nuclear) dead giants, more mud floods, smaller giants, more layers of war and mud -- this is hard to figure out who came first, and now the petrified remains of the giants called mud fossils are sticking out everywhere. We are building with, walking on, playing around, collecting, wearing as jewelry or use as ornaments -- dead things, or rather dead humans even if they're very large. We live on an exposed petrified open graveyard of earth's human history. These people are amusements for climbing and playing on, used as weapons, doorstops, and every imaginable thing that we have harvested their remains to make use of. Kind of weird when you really think about it. Need to do lots of research on each of the studies presented in my videos. Maybe everyone together can help put the fragments of our true history together one day.

Duke of Bridgewater 's canal, 1950's - Film 18885
Duke of Bridgewater 's canal, the first canal, by Brindley perhaps its Duke of Bridgwater inspected by a team of miners as it was owned by British Coal but flooded and abandoned. A pit head with the lift winding gear and a square brick building. This is Ellesmere pit coal mine near Manchester. The pit is now a pumping station. A close-up of a street sign which reads 'Bridgewater Road' on a brick wall. A map of the Midlands near Ellesmere while the commentary describes the 18th century Duke of Bridgewater who worked out the underwater canal system for working his coal. The road on which and then the headquarter building of the National Coal Board in Walken, it is a 19th century grand house. Three miners with helmets and Davy lamps enter a lift which a fourth operates. We see the three begin to descend in the lift cage. They are going to inspect the old canal network. Miners with lamps lit on the head descend a flight of metal stairs into a brick lined man made cavern. They step into a low flat bottomed boat, which was used by the 18th century miners. The boat enters the very low tunnel entrance. They have to lie flat, while someone else pushes the boat in - there is no engine. The edge of the boat seen going through the water. The raggy and uneven ceiling and walls of the tunnel pass over head. The miner move the boat by walking their feet on the ceiling. We see brick work arches and bare rock walls. Feet of miners in the air walking the ceiling. The inspection team of miners are Jimmy Stave and two Yugoslavian miners. They proceed through the passage. There is a marker post to show if the water level is too high or low for the boat to travel. Close-up of feet in boats and iron rings embedded in the ceiling. The canal is now used to drain off water from other colliery. A man in a helmet turns a round wheel on a series of pipes and water gushes out. A pressure gauge arrow goes up quickly. The inspection team emerges from a low tunnel in their boat at Worsley. A coal tug on the Worsley canal with NCB painted on the other side. A narrow boat in a covered dry dock. A NCB tug pulls a number of lighters near the half-timbered house in the background. The three miners climb out of their low boat and walk up the hill.

An annual event for Denim Enthusiast . Presented by www.darahkubiru.com & Indonesian Denim Group WALL OF FADES 2015 The Largest Denim Exhibition In Southeast Asia Denim Exhibition - Denim Education - Curated Preium Tenant Jeans are trousers that typically made from denim accompanied with the famous 5 pockets and rivets. It is used by the sailors in the Genoese Wars. They were called genes because they came from genoa, which now are simplfied and known as jeans. While the fabric itself, denim was from France or known as serge de nimes. It has been distributed and known through out sailing from time to time. In the 18th Century, cotton is getting more popular whereas back in the days, jeans were made from various mixture between fabrics. Through the durability of cotton, the use of this fabric is getting more demanded and being dyed with indigo color which being used as the most jeans nowadays. In the 1930, jeans became more popular due to the exposure in various films in hollywood, which jeans became identical with cowboys. Furthermore, the use of jeans is being used by many historical events such as wars and sub-culture movements, from mining to the way of people express them selves. Which the impact is huge and the distribution of jeans is known globally. Wall Of Fades 2015 will show various brands around the world including the details and differences of fades. The newest exhibition strikes with the Denim Enthusiast Dictionary in order for them to know denim and jeans more. And we want to show how sub-culture and countries represent their jeans in their own ways and point of views, so people would appreciate more.

Manganese - Video Learning - WizScience.com
"Manganese" is a chemical element with symbol "Mn" and atomic number 25. It is not found as a free element in nature; it is often found in combination with iron, and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Historically, manganese is named for various black minerals from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheele had used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite contained a new element, but they were unable to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon. Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ions have various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode material in zinc-carbon and alkaline batteries. In biology, manganese ions function as cofactors for a large variety of enzymes with many functions. Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms but is a neurotoxin. In larger amounts, and apparently with far greater effectiveness through inhalation, it can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.

Abandoned Mine Explore #3: Brownley Hill ( Enormous Stopes !) Nenthead, England, UK
Our exploration of the abandoned Brownley Hill lead mine. The following information is from mineexplorer.org : Brownley Hill mine was first worked for lead with silver being extracted as well, the earliest workings being via surface shafts on the Brownley Hill Vein. Records dated 1735 from the Greenwich Hospital indicate that the mine was of no real economic value at this time. In the middle of the 1700's the London Lead Company took out a lease for just under 20 years. They worked the Brownley Hill Vein in the Little Limestone and in the hazles above it, obtaining a considerable amount of ore, but they were prevented from mining deeper by water. To overcome the problem they drove the Brownley Hill High Level in the sills above the Great Limestone in an attempt to reach the Little Limestone gaining access to the bottom of old workings, however only a fraction of the expected ore was found. The company also tried the Brownley Hill Moss Cross Vein and Jug Vein, but due to poor ventilation they abandoned their undertakings in this area. In all, they gave up their lease before it was expired as the total current outlay on development brought forth very little in results. At the end of 1765 a new lease was taken out by two man team who obtained a very large amount of ore from the cross Veins as well as the Brownley Hill Vein. The ore raised was sold to the London Lead Company. In 1795 the lease passed to the newly formed Brownley Hill Lead Company. This was a particular lucrative time as the price of lead increased dramatically due to the wars with France. When the price declined again the lease was sold on to another group in 1816, which continued to work the mine under the same name of the Brownley Hill Lead Company. The mine now was being worked for zinc as well lead. It is during this period that the mine started to really develop. The Bloomsberry Horse Level was driven and the previously worked veins were now being worked from below. The horse level extended out on Guddamgill Cross Vein, Wellgill Cross Vein, Brownley Hill North Vein, Brownley Hill Vein eventually reaching the Brownley Hill Moss Cross and Brownley Hill High Cross Veins as well as Jug Vein. The lead ore in the lower levels were much poorer than that obtained in the higher horizons, however the grade of zinc ore was very good and this contributed to the operations profitability. Production was maintained until the middle of the 1850's. In 1869 the mine was operating under a different concern again, the Brownley Hill Lead Mining Company during this period the mine was closed for a while and then reopened again with the same workforce. In 1890 the company sold up the complete mining operation to the Nenthead and Tynedale Lead and Zinc Company who held the lease until 1894. At this time high grade lead ore was depleted and the Vieille Montagne Zinc Company took over the lease in 1914 shifting operations to the extraction of zinc ore. The mine operated until 1936. The last working of the mine was between 1964 and 1966; when the trial Slate Sill level was driven in the Slate Sills southeast of the Brownley Hill Moss Cross Vein.

CATACOMBS PARIS HISTORY Paris' Cemeteries. pearliest burial grounds were to the southern outskirts of the Roman-era Left Bank city. In ruins after the Roman empire's 5th-century end and the ensuing Frankish invasions, Parisians eventually abandoned this settlement for the marshy Right Bank: from the 4th century, the first known settlement there was on higher ground around a Saint-Etienne church and burial ground (behind the present Hôtel de Ville), and urban expansion on the Right Bank began in earnest after other ecclesiastical landowners filled in the marshlands from the late 10th century. Thus, instead of burying its dead away from inhabited areas as usual, the Paris Right Bank settlement began with cemeteries near its centre. The most central of these cemeteries, a burial ground around the 5th-century Notre-Dame-des-Bois church, became the property of the Saint-Opportune parish after the original church was demolished by the 9th-century Norman invasions. When it became its own parish associated with the church of the "Saints Innocents" from 1130, this burial ground, filling the land between the present rue Saint-Denis, rue de la Ferronnerie, rue de la Lingerie and the rue Berger, had become the City's principal cemetery. By the end of the same century "Saints Innocents" was neighbour to the principal Parisian marketplace Les Halles, and already filled to overflowing. To make room for more burials, the long-dead were exhumed and their bones packed into the roofs and walls of "charnier" galleries built inside the cemetery walls. By the end of the 18th century, the central burial ground was a two metre high mound of earth filled with centuries of Parisian dead, plus the remains from the Hôtel-Dieu hospital and the Morgue; other Parisian parishes had their own burial grounds, but the conditions in Les Innocents cemetery were the worst. A series of ineffective decrees limiting the use of the cemetery did little to remedy the situation, and it was not until the late 18th century that it was decided to create three new large-scale suburban burial grounds on the outskirts of the city, and to condemn all existing parish cemeteries within city limits. The future ossuary: Paris' former mines Edit Map of former underground mine exploitations in Paris (1908). Further information: Mines of Paris Much of the Left Bank area rests upon rich Lutetian limestone deposits. This stone built much of the city, but it was extracted in suburban locations away from any habitation. Because of the post 12th-century haphazard mining technique of digging wells down to the deposit and extracting it horizontally along the vein until depletion, many of these (often illicit) mines were uncharted, and when depleted, often abandoned and forgotten. Paris had annexed its suburbs many times over the centuries, and by the 18th century many of its arrondissements (administrative districts) were or included previously mined territories. The undermined state of the Left Bank was known to architects as early as the early 17th-century construction of the Val-de-Grâce hospital (most of its building expenses were due to its foundations), but a series of mine cave-ins beginning 1774 with the collapse of a house along the "rue d'Enfer" (near today's crossing of the Avenue Denfert-Rochereau and the boulevard Saint-Michel) caused King Louis XVI to name a commission to investigate the state of the Parisian underground. This resulted in the creation of the inspection Générale des Carrières (Inspection of Mines) service. Ossuary creation Edit The need to eliminate Les Innocents gained urgency from May 31, 1780, when a basement wall in a property adjoining the cemetery collapsed under the weight of the mass grave behind it. The cemetery was closed to the public and all intra muros (Latin: "within the [city] walls"[2]) burials were forbidden after 1780. The problem of what to do with the remains crowding intra muros cemeteries was still unresolved. Mine consolidations were still occurring and the undergroun

Places to see in ( Roussillon - France )
Places to see in ( Roussillon - France ) Roussillon is a commune in the Vaucluse department in the Provence-Alpes-Côte d'Azur region in southeastern France. Roussillon lies within the borders of the Parc Naturel Régional du Luberon. In the French natural regional parks, new economic activities may be developed only if they are sustainable. Roussillon is noted for its large ochre deposits found in the clay surrounding the village. Ochres are pigments ranging from yellow and orange to red. One of the former ochre quarries can be visited via the "Sentier des Ocres" (Ochre Path), a walk of either 30 or 60 minutes through the old workings. Roussillon stands on an ochre ridge, situated in a broad valley with the "Monts du Vaucluse" to the north and the "Petit" Luberon to the south. The nearest railway station is in Cavaillon; the nearest TGV station is in Avignon. The river Calavon forms part of the commune's southern border. Roussillon is famous for the rich deposits of ochre pigments found in the clay near the village. The large quarries of Roussillon were mined from the end of the 18th century until 1930. Thousands of people found work in the quarries and factories. Nowadays the mining of ochre is prohibited here, in order to protect the sites from degradation or even complete destruction. Because during the 18th century the demand rose for pigments to be used in the textile industry, the mining of ochres in Roussillon intensified. Numerous quarries and ochre factories, some of which can still be seen today, were situated near the village. One example of an ochre factory, the "Usine Mathieu", is named for the family that owned it from 1870 to 1901. It has been formed into a "Conservatoire": a workshop serving as a museum. The quarries and factories were established in the villages of Roussillon, Villars, Gargas, Rustrel (with its Colorado provençal) and Gignac. During the 20th century, mining techniques were modernized, which meant that more profitable ochre mines became exploitable. This resulted in a gradual closing-down of ochre mines in and around Roussillon. From the 1980s, tourism has replaced ochre industry as a source of income. ( Roussillon - France ) is well know as a tourist destination because of the variety of places you can enjoy while you are visiting the city of Roussillon .

The Renaissance: Was it a Thing? - Crash Course World History #22
In which John Green teaches you about the European Renaissance. European learning changed the world in the 15th and 16th century, but was it a cultural revolution, or an evolution? We'd argue that any cultural shift that occurs over a couple of hundred years isn't too overwhelming to the people who live through it. In retrospect though, the cultural bloom in Europe during this time was pretty impressive. In addition to investigating what caused the Renaissance and who benefitted from the changes that occurred, John will tell you just how the Ninja Turtles got mixed up in all this.

This list of places are not typical vacation destinations by any stretch and are sure to haunt anyone who visits them. These are the 5 Most Scary & Creepy Places on Earth. 5. Paris Catacombs Hailed as the "City of Lights," Paris is known the world over for its romantic allure and beautiful sights. But there’s something underneath all charm, something unlike anything else in the world that will send chills down your spine. And that’s The existence of the Paris catacombs. Even before the city came to be, Parisian underground mines and quarries were widespread. These mines were built haphazardly and were once used to quarry limestone for constructing buildings, as well as gypsum, used in "plaster of Paris." Ever since its discovery, the mines have been found to have three large networks that run underground in several districts of the city. 4. Snake Island If you're deathly afraid of snakes, there's one island you should stay away from – Ilha Queimada Grande, otherwise known as Snake Island. Located off the coast of Brazil, Snake Island was cut off from the mainland by rising sea levels during the last Ice Age. Featuring 4.6 million square feet of land, this place is mostly covered in a thick rainforest and open grasslands. The island was once inhabited. Those who occupied it attempted to create a banana plantation and used the slash and burn technique to clear out a portion of land for planting. 3. Island of the Dolls Considered a haunted island, the Island of the Dolls can be reached in a 2-hour canal drive from Mexico City. An actual floating garden, the island amps up the creepy factor with the hundreds of dolls and doll parts decorating the trees and various areas of the island. According to legend, La Isla de las Muñecas came to be because of one man, a local named Don Julian Barrera. A hermit, he lived on one of the small islands inside the Xochimilco canal system and One day, he came across a little girl that drowned under mysterious circumstances. 2. Capuchin Catacombs of Palermo Mummies aren't just found in Egypt they're also found on the beautiful island of Sicily. The city of Capuchin is located on the outskirts of Palermo; in it, is found the famously creepy Capuchin Monastery. During the 16th century, the monastery ran out of space for their cemetery and decided to excavate beneath the church. It’s there they created various crypts, which were originally designed to host the mummified bodies of dead monks. The first monk mummified and placed underneath here was Silvestro of Gubbio in 1599 while the last monk interred was Brother Ricardo in 1871. 1. Beelitz-Heilstätten Hospital, Beelitz, Germany Built in the later part of the 18th century, the Beelitz-Heilstätten Hospital otherwise known as the Beelitz Sanatorium was initially created to help rehabilitate tuberculosis patients. It was built from 1898 to 1930 under the direction of the German National Insurance Institute. They thought that the proximity of the area to the capital as well as the fresh countryside air would make the perfect location to help patients. It was built with 60 buildings consisting mostly of treatment facilities, but there was also a small village in the area along with a bakery, restaurant, butcher's post, a post office and even a power station.

What is CALAMINE BRASS? What does CALAMINE BRASS mean? CALAMINE BRASS meaning & explanation
What is CALAMINE BRASS? What does CALAMINE BRASS mean? CALAMINE BRASS meaning - CALAMINE BRASS definition - CALAMINE BRASS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Calamine brass is brass produced by a particular alloying technique using the zinc ore calamine directly, rather than first refining it to metallic zinc. Zinc smelting is difficult and the pure metal was largely unknown historically, even though the alloyed calamine brass was in use for centuries. Brass is an alloy of copper and zinc and, when it was first developed, methods for producing metallic zinc were unknown. Metallurgists wishing to produce brass thus used calamine (actually a mixture of the virtually indistinguishable zinc ores smithsonite and hemimorphite) as the zinc component of brass. The resulting brasses, produced by heating a mixture of copper and calamine to a high temperature for several hours (allowing zinc vapor to distill from the ores and permeate the metallic copper), contained a significant amount of slag material resulting from the non-zinc components of calamine. The use of ore rather than metallic zinc also made it difficult to accurately produce the desired final proportion of copper to zinc. This process is known as cementation. Calamine brass was produced using proportions of two-sevenths fine copper, four-sevenths calamine, and one-seventh shruff (old plate brass). Calamine brass was the first type of brass produced, probably starting during the 1st millennium BC, and was not replaced in Europe by other brass manufactures until the 18th century (it is likely that Indian brass manufacturers had developed more advanced techniques some centuries earlier). The area around La Calamine, now Kelmis, in Belgium, was the source of much of the medieval brass of northern Europe. Brass production was introduced to England in 1587 when several members of the Company of Mineral and Battery Works obtained a licence from the company (within whose monopoly it was) to build a brass works at Isleworth. However a decade later the company obstructed the owners from mining calamine. A plaque at Tintern Abbey claims that the well-known brassworks at this site began in 1568. New brass works were built by Jacob Momma, a German immigrant in 1649 at Esher, probably using Swedish copper. After the passing of the Mines Royal Act in 1689, further works were built near Bristol, where brass production became a major industry in the 18th century. Later brass production sites in England included Cheadle and Birmingham. Calamine brass was slowly phased out as zinc smelting techniques were developed in Europe, which produced metallic zinc more suitable for brass production than calamine. However, the conversion away from calamine brass manufacture was slow; a British patent was awarded to William Champion in 1738, but the alloying of metallic zinc and copper to produce brass was not patented until 1781 (by James Emerson), and calamine brass mills persisted in South Wales until as late as 1858. The slow diffusion of this technology was probably the result of economic factors.

Forehead lines reader: 18th century dating matchmaker
This German forehead reader from 1785 was aimed at those looking for love and marriage. The readers interpreted the lines on the forehead in the same way that palmistry does for the hand. Based on physiognomy, it was believed to help judge aspects of someone's character, revealing a jealous person behind an attractive façade. Was this therefore an analogue dating device?

Top 10 Largest Cities or Towns of Papua New Guinea
Thanks for watching..... 1. Port Moresby 2. Lae 3. Arawa 4. Mount Hagen 5. Madang 6. Wewak 7. Goroka 8. Kokopo 9. Popondetta 10. Aitape Music : Yessum,Jingle Punks; YouTube Audio Library Papua New Guinea, officially the Independent State of Papua New Guinea, is an Oceanian country that occupies the eastern half of the island of New Guinea and its offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. Its capital, located along its southeastern coast, is Port Moresby. The western half of New Guinea forms the Indonesian provinces of Papua and West Papua. Papua New Guinea is one of the most culturally diverse countries in the world. 848 languages are listed for the country, of which 12 have no known living speakers. Most of the population of over 7 million people live in customary communities, which are as diverse as the languages. It is also one of the most rural, as only 18 per cent of its people live in urban centres. The country is one of the world's least explored, culturally and geographically, and many undiscovered species of plants and animals are thought to exist in the interior. Strong growth in Papua New Guinea's mining and resource sector has led to the country's becoming the sixth fastest-growing economy in the world as of 2011. Many people in the country live in extreme poverty when measured in terms of money, with about one-third of the population living on less than US$1.25 per day. At the local level, the majority of the population still live in strong customary societies and - while social life is overlaid with traditional religious cosmologies and modern practices, including conventional primary education - customary subsistence-based agriculture remains fundamental. These societies and clans are explicitly acknowledged within the nation's constitutional framework. The Papua New Guinea Constitution expresses the wish for "traditional villages and communities to remain as viable units of Papua New Guinean society" and for active steps to be taken in their continuing importance to local and national community life. At the national level, after being ruled by three external powers since 1884, Papua New Guinea established its sovereignty in 1975 following 70 years of Australian administration. It became a separate Commonwealth realm with Queen Elizabeth II as its head of state and became a member of the Commonwealth of Nations in its own right. Agriculture was independently developed in the New Guinea highlands around 7000 BC, making it one of the few areas in the world where people independently domesticated plants. A major migration of Austronesian speaking peoples to coastal regions of New Guinea took place around 500 BC. This has been correlated with the introduction of pottery, pigs, and certain fishing techniques. More recently, in the 18th century, the sweet potato was brought to New Guinea, having been introduced to the Moluccas by Portuguese traders, who obtained it from South America. The far higher crop yields from sweet potato gardens radically transformed traditional agriculture; sweet potato largely supplanted the previous staple, taro, and gave rise to a significant increase in population in the highlands. Although headhunting and cannibalism have been practically eradicated, in the past they were practised in many parts of the country as part of rituals related to warfare and taking in enemy spirits or powers. For example, in 1901, on Goaribari Island in the Gulf of Papua, a missionary, Harry Dauncey, found 10,000 skulls in the island's Long Houses. According to the writer Marianna Torgovnick, "The most fully documented instances of cannibalism as a social institution come from New Guinea, where head-hunting and ritual cannibalism survived, in certain isolated areas, into the Fifties, Sixties, and Seventies, and still leave traces within certain social groups." Little was known in Europe about the island until the 19th century, although Portuguese and Spanish explorers, such as Dom Jorge de Meneses and Yñigo Ortiz de Retez, had encountered it as early as the 16th century. Traders from Southeast Asia had visited New Guinea beginning 5,000 years ago to collect bird of paradise plumes. The country's dual name results from its complex administrative history before independence. The word papua is derived from an old local term of uncertain origin. "New Guinea" (Nueva Guinea) was the name coined by the Spanish explorer Yñigo Ortiz de Retez. In 1545 he noted the resemblance of the people to those he had earlier seen along the Guinea coast of Africa. Source: http://en.wikipedia.org/wiki/Papua_New_Guinea

Historic Techniques - History through Tin-Types
This event took place on Thursday, September 3, 2015 at the California Historical Society. Photographer Ed Drew's first body of work involved photographing his military unit in Afghanistan in the photographic technique of wet plate tintype. Created in between the combat missions he flew on as a combat search and rescue gunner on helicopters, this collection of photographs were the first made of American soldiers in war since the Civil War. For his most recent work he was commissioned by the Klamath tribes of Oregon in conjunction with Klamath Tribal Health services, which included Modoc tribal members whom were relocated from their homelands in Tule Lake California after the Modoc War. The work speaks of a reflection of the past to show the progression of the contemporary, while redefining the tribal peoples definition of self as strong proud individuals. Ed Drew was born and raised in Brooklyn, NY and joined the military in 1999 2 days after his 18th birthday. He has served for 6 years in the active duty Air Force and transferred to the California Air National Guard where he currently serves as a Staff Sergeant and helicopter gunner on Combat Search and Rescue helicopters stationed in Moffett Field, near Mountain View, California. He is also a recent graduate of San Francisco Art Institute where he received a BFA majoring in Sculptor and minoring in Photography. He currently lives in East Bay.

Boutique Big Data: Reintegrating Close and Distant Reading of 19th-Century Newspapers
27-10-2015 Institute of Historical Research http://www.sas.ac.uk/ http://www.history.ac.uk/events/browse/18566 Institute: http://www.history.ac.uk Boutique Big Data: Reintegrating Close and Distant Reading of 19th-Century Newspapers Dr Melodee Beals (Loughborough University) From their earliest incarnations in the seventeenth-century, through their Georgian expansion into provincial and colonial markets and culminating in their late-Victorian transformation into New Journalism, British newspapers have relied upon scissors-and-paste journalism to meet consumer demands for the latest political intelligence and diverting content. Although this practice, wherein one newspaper extracted or wholly duplicated content from another, is well known to scholars of the periodical press, in-depth analysis of the process is hindered by the lack of formal records relating to the reprinting process. Although anecdotes abound, attributions were rarely and inconsistently given and, with no legal requirement to recompense the original author, formal records of where material was obtained were unnecessary. Even if they had existed, the number of titles that relied upon reprinted material makes systematic analysis impossible; for many periodicals, only a few issues, let alone business records, survive. However, mass digitisation of these periodicals, in both photographic and machine-readable form, offers historians a new opportunity to rediscover the mechanics of nineteenth-century reprinting. By undertaking multi-modal and multi-scale analyses of digitised periodicals, we can begin to reconstruct the precise journeys these texts took from their first appearance to their multiple ends. Moreover, by repurposing individual ‘boutique’ research outputs within large-scale textual analyses, we can greatly enhance the resolution of our computer-aided conclusions and bridge the gaps between commercial, state and private databases. This paper will explore the possibilities of large-scale reprint identification, using out-of-the-box and project-specific software, within and across digitised collections. Second, it will demonstrate the means by which reprint directionality and branching can be achieved and the relative precision of manual and computer-aided techniques. Finally, it will explore the nature of multi-scale analysis and how we might best reintegrate ‘boutique’ periodical research into large-scale text-mining projects. Digital History seminar series

Creative Commons License for Kevin MacLeod, Link... http://creativecommons.org/licenses/by/3.0/legalcode Information from... From Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Root_beer Root beer is a carbonated, sweetened beverage, originally made using the root of the sassafras plant (or the bark of a sassafras tree) as the primary flavor. Root beer, popularized in North America, comes in two forms: alcoholic and soft drink. The historical root beer was analogous to small beer in that the process provided a drink with a very low alcohol content. Although roots are used as the source of many soft drinks throughout the world, often different names are used. Ingredients There are hundreds of root beer brands in the United States, produced in every U.S. state. It is a flavor almost exclusive to North America, yet there are a few brands from other nations around the world, such as the UK, the Philippines, and Thailand where the flavor often varies considerably from the typical North American drink. There is no standardized recipe. The primary ingredient, artificial sassafras flavoring, is complemented with other flavors. Common flavorings are vanilla, wintergreen, cherry tree bark, licorice root, sarsaparilla root, nutmeg, acacia, anise, molasses, cinnamon, clove, and honey. Although most mainstream brands are caffeine-free, there are some brands and varieties that contain caffeine. Homemade root beer is usually made from concentrate, though it can also be made from actual herbs and roots. Both alcoholic and non-alcoholic root beers have a thick and foamy head when poured, often enhanced by the addition of yucca extract. The flavor varies widely between brands and methods--from insipid and insignificant to a bold, rambunctious brew which lingers in the back of the throat and pleasantly makes itself manifest even in the nasal passageways, a hallmark of only the rootiest root beers. The discontinuation of the use of sassafrass root is thought by some to make the difference here. History The custom of brewing root beer goes back to the 18th century.[citation needed] Farm owners used to brew their own (then) light-alcoholic beverage for family get-togethers and other social events. During the 19th century, some pharmacists tried to sell their version of root beer as a miracle drug. In 1876, pharmacist Charles Hires first introduced a commercial version at the Philadelphia Centennial Exhibition. Hires was a teetotaler who wanted to call the beverage "root tea." However, his desire to market the product to Pennsylvania coal miners caused him to call his product "root beer" instead. By 1893, root beer was sold as a bottled soft drink to the public. Especially during Prohibition, non-alcoholic versions proved to be commercially successful. In 1960, a key ingredient (the sassafras root) came to be known as a carcinogen and its use was banned by the U.S. Food and Drug Administration.[citation needed] Following this ban, companies began experimentation with artificial flavors and preparation techniques to remove the unhealthy effects of root beer while preserving its flavor.

They were made of brass, but we're used to measure gold dust which was the universal currency in West Africa at the time. Weights often featured animals, fish, weapons and tools – or human figures as demonstrated here. Their significance as an art form transcends their function and reflects wider Asante spiritual beliefs and cultural practises.

Gaia 1
In the latter years of the 18th century, astronomers William and Caroline Herschel began to count stars. William called the technique 'star gauging' and his aim was to determine the shape of our Galaxy. Ever since 1609, when Galileo lifted his telescope to the misty patch of light known as the Milky Way and saw that it was composed of myriad faint stars whose light all blurred together, we have known that there are different numbers of stars in different directions throughout space. This means that our local collection of stars, the Galaxy, must have a shape to it. Herschel set out to find out what that shape was. He used a large telescope, twenty feet (610 cm) in length, mounted between tall wooden frames to sweep out a large circle in the sky that passed through the Milky Way at right angles. He then split this circle into more than 600 regions and counted or estimated the number of stars in each. With this simple technique the Herschels produced the first shape estimate for the Galaxy. Fast-forward to the 21st century and now researchers use star counts to search for hidden star clusters and satellite galaxies. They look for regions where the density of stars rises higher than expected. These patches are called stellar over-densities. Back in 1785, Herschel's circular track passed close to the brightest star in the night sky Sirius. Now, scientists mining the first data released from the ESA spacecraft Gaia have revisited that particular area of the sky and made a remarkable discovery. They have revealed a large star cluster that could have been discovered more than a century and a half ago had it not been so close to Sirius. Astronomers have been looking for star clusters and satellite galaxies in various surveys for the past decade. It was natural for them to do this with the Gaia mission's first data release. Gaia is the European Space Agency's astrometric mission. Collecting positions, brightnesses and additional information for more than a billion sources of light, its data allows nothing less than the most precise 'star gauging' ever. These days the laborious task of counting the stars is done by computers but the results still have to be scrutinised by humans. Astonomers were combing the list of over-densities when they saw the massive cluster. At first it seemed too good to be true. Bright stars can create false signals, termed artefacts, that astronomers must be careful not to mistake for stars. An early paper from the Gaia team had even discussed artefacts around Sirius using a nearby patch of sky to the one Koposov was looking at. These two objects were named: Gaia 1 for the object located near Sirius, and Gaia 2, which is close to the plane of our Galaxy, and both were duly published. Gaia 1 in particular contains enough mass to make a few thousand stars like the Sun, is located 15 thousand light years away, and spread across 30 light years. This means it is a massive star cluster. Collections of stars like Gaia 1 are called open clusters. They are families of stars that all form together and then gradually disperse around the Galaxy. Our own Sun very likely formed in an open cluster. Such assemblies can tell us about the star formation history of our Galaxy. Finding a new one that can be easily studied is already paying dividends. Identifying 41 members of the cluster, astonomerss found that Gaia 1 is unusual in at least two ways. Firstly, it is about 3 billion years old. This is odd because there are not many clusters with this age in the Milky Way. Typically clusters are either younger than a few hundred million years – these are the open clusters – or older than 10 billion years – these are a distinct class called globular clusters, which are found beyond the main bulk of stars in our Galaxy. Being of intermediate age, Gaia 1 might represent an important bridge in our understanding between the two populations. Secondly, its orbit through the galaxy is unusual. Most open clusters lie close to the plane of the Galaxy but Simpson found that Gaia 1 flies high above it before ducking down and passing underneath. About 90% of clusters never go more than a third of this distance. Simulations of clusters with orbits like Gaia 1 find that they are stripped of stars and dispersed by these high velocity 'plane passages'. That puts it at odds with the age estimate.

Metal Detecting Tips: Research
Taking time to research a site will pay off. Search the area on Google to see what comes up. Parish records, battle sites, mines, old maps - they can all be found on the internet. Google Earth will show up sites of old houses, footpaths, ancient water courses etc. which may be invisible from ground level. Talk to old people - they've been around a long time and will have knowledge of local history. That's helped me alot with the sites I have. Above all, use common sense. If there are modern features like a cross roads, the fields around there (assuming the roads have been used for hundreds of years) could have many finds waiting to be discovered. The shape of the land can indicate ancient farming methods also with 'rig and furrow' (undulating land caused by years of linear ploughing) showing that people have worked the land in the past, even if now, the field is just pasture. Thanks to the lads in the Blayon Search and Recovery Association for teaching me so much in the short time I have been a member.

Authenticity in Museum Education
Accessing authentically produced objects for education programs represents an ongoing challenge for Sydney Living Museums. So, when the education team realised that the wooden buckets at Elizabeth Farm needed replacing the hunt was on to get some new ones – but where do you go? And how do you make a bucket? Thankfully, a bit of research put us onto George Smithwick – a sixth generation cooper who makes buckets and is continuing a family tradition that began in the 18th century in Ireland. Edward Washington and James Murray from the Programs team flew down to catch up with George to see if he could help with our dilemma and he was happy to show us how he worked; using tools, techniques and practises that have remained the same for hundreds of years. George also let us into what was once a very tight-knit and sometimes secretive coopering industry – and we captured it all on camera.
Columbus, de Gama, and Zheng He! 15th Century Mariners. Crash Course: World History #21
In which John Green teaches you about the beginning of the so-called Age of Discovery. You've probably heard of Christopher Columbus, who "discovered" America in 1492, but what about Vasco da Gama? How about Zheng He? Columbus gets a bad rap from many modern historians, but it turns out he was pretty important as far as the history of the world goes. That said, he wasn't the only pioneer plying the seas in the 1400s. In Portugal, Vasco da Gama was busy integrating Europe into the Indian Ocean Trade by sailing around Africa. Chinese admiral Zheng He was also traveling far and wide in the largest wooden ships ever built. Columbus, whether portrayed as hero or villain, is usually credited as the great sailor of the 15th century, but he definitely wasn't the only contender. What better way to settle this question than with a knock-down, drag-out, no holds barred, old-fashioned battle royal? We were going to make it a cage match, but welding is EXPENSIVE.

Combat diver history - In ancient Roman and Greek times, etc., there were instances of men swimming or diving for combat, sometimes using a hollow plant stem or a long bone as a snorkel. Diving with snorkel is mentioned by Aristotle (4th century BC). The earliest descriptions of frogmen in war are found in Thukydides' History of the Peloponnesian War. The first instance was in 425 BC, when the Athenian fleet besieged the Spartans on the small island of Sphacteria. The Spartans managed to get supplies from the mainland by underwater swimmers towing submerged sacks with supplies. In another incident of the same war, in 415 BC, the Athenians used combat divers in the port of Syracuse, Sicily. The Syracuseans had planted vertical wooden poles in the bottom around their port, to prevent the Athenian triremes from entering. The poles were submerged, not visible above the sea level. The Athenians used various means to cut these obstacles, including divers with saws. It is believed that the underwater sawing required snorkels for breathing and diving weights to keep the divers stable. The Hungarian Chronicon Pictum claims that Henry III's 1052 invasion of Hungary was defeated by a skillful diver who sabotaged Henry's supply fleet. The unexpected sinking of the ships is confirmed by German chronicles. Italy started World War II with a commando frogman force already trained. Britain, Germany, the United States, and the Soviet Union started commando frogman forces during World War II. First frogmen The word frogman appeared first in the stage name The Fearless Frogman of Paul Boyton, who since the 1870s broke records in long distance swimming to demonstrate a new invented rubber immersion suit, with an inflated hood shaped like a frog. As a stunt show hero in that suit he played a military diver (attaching mines to ships etc.) long before such divers existed. The first modern frogmen were the World War II Italian commando frogmen, of Decima Flottiglia MAS (now "ComSubIn": Comando Raggruppamento Subacquei e Incursori Teseo Tesei) which formed in 1938 and was first in action in 1940. Originally these divers were called "Uomini Gamma" because they were members of the top secret special unit called "Gruppo Gamma", which originated from the kind of Pirelli rubber skin-suit nicknamed muta gamma used by these divers. Later they were nicknamed "Uomini Rana", Italian for "frog men", because of an underwater swimming frog kick style, similar to that of frogs, or because their fins looked like frog's feet. This special corps used an early oxygen rebreather scuba set, the Auto Respiratore ad Ossigeno (A.R.O), a development of the Dräger oxygen self-contained breathing apparatus designed for the mining industry and of the Davis Submerged Escape Apparatus made by Siebe, Gorman & Co and by Bergomi, designed for escaping from sunken submarines. This was used from about 1920 for spearfishing by Italian sport divers, modified and adapted by the Italian navy engineers for safe underwater use and built by Pirelli and SALVAS from about 1933, and so became a precursor of the modern diving rebreather. For this new way of underwater diving, the Italian frogmen trained in La Spezia, Liguria, using the newly available Genoese free diving spearfishing equipment; diving mask, snorkel, swimfins, and rubber dry suit, the first specially made diving watch (the luminescent Panerai), and the new A.R.O. scuba unit. This was a revolutionary alternative way to dive, and the start of the transition from the usual heavy underwater diving equipment of the hard hat divers which had been in general use since the 18th century, to self-contained divers, free of being tethered by an air line and rope connection.

Egypt’s Most Influential Pharaoh Last year, in 2017, National Geographic reported that archaeologists from Egypt and Germany had discovered a huge eight-metre statue submerged in ground water in Cairo. The statue at first was believed to depict Pharaoh Ramses II, who ruled Egypt over 3,000 years ago and was one of the country’s most powerful leaders. 8. Elite Tombs in Luxor The discovery of two ancient tombs in the southern city of Luxor surprised the world and brought new buzz to Egypt in 2017. Located in the the Draa Abul Naga necropolis, this area is famous for its temples and burial grounds. It is close to the Valley of the Kings where many of ancient Egypt's pharaohs were buried. 7. A Nubian King In 2008, the remains of a mysterious 2,600-year-old statue were discovered in a temple at Dangeil, along the Nile River in Sudan. However, archeologists found only parts of the statue, which meant they could not identify who it was until years later. The temple where the remains were found are believed to have once been dedicated to the Egyptian Amun. 6. The Ankhesenpepi Pyramid Archaeologists have discovered the first evidence of a long-lost satellite pyramid for the ancient Egyptian Queen Ankhesenpepi II. She was considered the most important Egyptian queen of the 6th Dynasty around 2,350 BC. She and her sister Ankhesenpepi I were both married to Pharaoh Pepi I. While the names might seem like a huge coincidence, it is most likely that they both took on the same name when they married. 5. Remains of a Musician In Timna, Israel, archaeologists discovered the mysterious remains of a pregnant woman from 3,200 years ago. This biblical-era site supposedly never had any female visitors and during the time of her the place was controlled by Egypt. This discovery last year challenged the historical understanding of experts. 4. The Statue of Ptah In 2014, archaeologists discovered a pit full of ancient goodies! Among them, a statue of the Egyptian Ptah, alongside a beautiful carved cat, a sphinx, and a Baboon. Ptah was the of craftsmen and sculptors and was worshipped in a temple at Karnak. 3. Tutankhamen’s Camping Bed When famous archaeologist Howard Carter discovered King Tut’s tomb in 1922, he also discovered some furniture in his treasury. While this might not sound that exciting compared to everything that was found, it definitely deserves its own mention. 2. A Hidden Chamber After years of analysis and exploration, researchers believed they had uncovered every secret hidden inside the pyramid of Giza, however in 2017 a new chamber was revealed! This 4500-year-old monument and wonder of the world has much more to share. Researchers used muon detectors, the by-product of cosmic rays to reveal the unidentified chamber. 1. The Two Brothers In 1907, the findings of two mystery mummies left researchers perplexed for decades, but now, thanks to DNA sequencing, scientist have finally solved the mystery!! The pair’s burial site was discovered in, a village 250 miles south of Cairo. They were found by Egyptian workmen directed Origins Explained is the place to be to find all the answers to your questions, from mysterious events and unsolved mysteries to everything there is to know about the world and its amazing animals!

[Techno Blog] 10 Historic Photos You’ve Probably Never Seen!
10 Historic Photos You’ve Probably Never Seen! 10. The Punt Gun Used in late 19th and early 20th Century, this mechanized shot gun with devastating rounds was probably sufficient to scare an enemy into a quick submission. Equipped with an intimidating looks and high explosive power, these weapons of gore however saw no significant grim battle. 9. The Elephant-Mounted Machine Gun Animals played a vital role in the World Wars and they are one of man’s most venerated friend. To tame these monsters, we had to venture past our fear of gore to transform an elephant into a death merchant. In this publicity snap taken in 1914, an American corporal is seen aiming his M1895Colt-Browning machine gun atop an elephant. 8. A Soldier On A Mountain Of Shells World War I is one the most vicious battle ever fought in history of humanity. What started as a normal outing for Archduke Franz Ferdinand and his wife, an erroneous turn by the driver and sheer coincidence of stumbling upon Gavrilo Princip on a street corner led to the fatal assassination that ultimately sparked a series of events that subsequently led to the outbreak of the war. 7. The Football Helmet Test Prior to the age of computer simulators, men had to test things they way they saw fit. In this hilariously-brutal yet justified photo snapped in 1912. An unnamed man is seen ramming head first into a wooden structure to test the strength of the primitive helmets. Prior to the helmets, the late 18th and early 19th Century players protected their ears and head using leather straps lased with cotton. 6. Atabrine Promotional Post When fear of death and insecurity combine on hysterical masses, few unscrupulous business-minded men are bound to whistle all the way to the bank. In this historical photo of killing two birds with a single stone, two human skulls are used as both fear and marketing technique. From this grim photo that violates the dead, an anti malarial (Atabrine) is advertised in a draconian and carefree fashion. What haunts most is the poster in question was strategically placed in 363rd Station Hospital. 5. The Rat Catchers You’ve all heard of rat-catchers. A group of penniless and despised citizens employed to chase and kill rats in a bid to tame their sporadic sprouting across the cities. Still reeling in shock and frenzy of the black and bubonic plague, authorities went to extreme lengths to keep them ‘’death merchants’’ under wraps. These rodent-timers spent hours toiling in the belly of the earth; sewers and cellars as mice shun open areas. 4. The Unpleased German Crewman In this photo that sums the rascal natures of combat, a German U-boat crewman is seen totally unpleased with the state of affairs. As a crew of the dreaded U-boat, the patrol took weeks or months. During those ‘’red-set-tape’’ period in the belly of the mechanized death machines, they had to be on guard against enemy submarines as well as spy radars, all while avoiding catastrophic collision with mines in addition to watching the skies for bombers. 3. George Blind While most of us would freeze at the sight of a gun, George Blind was a different one altogether. Equipped with nerves of steel, George took the bull by the horn by literally smiling on the face of his supposed executioners. After being arrested on suspicion of being a French partisan; accusations that didn’t seat well with the third Reich, he was promptly whisked to interrogation chambers but amazingly failed to crack. 2. NASA Board Of Calculations NASA is one of worlds most advanced space program where photos from space voyagers are analyzed by bored scientists before released to the uneducated eyes who marvel at the complexity and immensity of our universe. However, the pre-computer NASA was a different one. Complex spacecraft trajectories, navigation and orbits of spacecrafts were often calculated on the board and this notable photo snapped in their offices attest to that. 1. Titanic Funeral Mass We all know Titanic was one of the most luxurious ship made in the early 1900’s. Needless to say, the operators swiftly criss-crossed the ship and right away branded her ‘’unsinkable’’. To the masses, she was a dream come true. However, we know nothing goes according to plan when you poke your proverbial middle finger in the face of doom and nature taught us the hard way.

Sourdough Bread Starter A Simple homemade sourdough starter for baking sourdough bread.
Sourdough bread is one of those things anyone can bake, but almost nobody ever tries, because they mistakenly think baking bread is hard. It isnt! For thousands of years, by some accounts, more than 5,000, the leavening of bread and fermentation of alcoholic beverages, like beer has been accomplished through time and patience with a little help from some voracious little microbes. Fast forward several millennia to the 1800’s and we have the California gold rush and the mining boom. It is during this time that we have acquired the image of “Sourdough Sam” the gold prospector, carrying a little leather pouch of old dough from the last batch of bread, next to his skin in a little leather pouch, to have a ready sample of gooey yeast for raising his bread or other baked goods. Doesn’t that sound appetizing? Through the ages, the entire process was thought of to varying degrees as divinely inspired, or magical. Nobody knew how it happened to make the bread rise, just that it did, and bread was better because of it. Mention sourdough bread to people, and most of us will immediately respond with images of a San Franciscan “Sourdough Sam” type of bread. Equally adored and reviled depending on whom you speak with, this overly “tart and tangy” version of wild yeast leavening has become ubiquitous with the word sourdough. This is unfortunate in my opinion. The word “sourdough” is itself the cause of the problem. The very word makes you think “sour”. Which is a misnomer. The word was accurate “back in the day” when the San Francisco version of bread leavening derived from miners carrying around a small portion of dough in a leather sack, next to their skin, which they would use to leaven their baked goods when they got back to camp. When modern yeast became prevalent and profitable, bakers and bakeries slowly adopted the “newly” discovered magical bread bug, and eventually gave up the time-honored tradition of slow leavened bread and baked goods. At first it was hailed as a miracle of modern ingenuity and innovation, but, overtime people began to look at their square, plastic wrapped bread and realized… something was missing. Like, taste, perhaps? People started to wonder what happened to the bread that grandma made when they were young, and they swear tasted so amazing, it still made their mouth water just thinking about it, decades later. Some enterprising people began investigating what happened, and it really wasn’t long to discover what had almost been forgotten, almost lost to history was how to make bread with patience, and natural leavening. Naturally leavened bread, or what has become to be called sourdough baking and bread baking specifically has gone through a dramatic reawakening in recent years, the word artisan has become almost commonplace. But, for all that, the driving technique that is making this all possible, is natural yeast leavening. Wild Yeast… or sourdough starter.
