Claim of supersolid helium disproved by original researcher

first_img Citation: Claim of supersolid helium disproved by original researcher (2012, October 15) retrieved 18 August 2019 from Solid objects hold their shape due to a lattice structure made of atoms. Quantum theory suggests that under very cold conditions, quantum effects can cause some of the atoms in a structure to begin to move freely, thereby acting as a frictionless liquid, resulting in a supersolid. Chan and his earlier partner Eunseong Kim believed they had proven the existence of supersolid helium after conducting an experiment that involved cooling helium that had been collected inside of a type of glass known as Vycor. The helium-glass mixture was hung from a chamber that was spun in first one direction, then the other, oscillating back and forth. As the temperature was brought down, the researchers noted that the oscillation rate increased. This, they claimed, was the result of some of the helium atoms inside slipping between the others in the lattice—a clear sign of a supersolid. Three years later, a team led by John Beamish suggested that bulk helium, rather than becoming a supersolid as it was cooled, instead became stiffer, accounting for the increased oscillation rate found by Chan and Kim. Subsequent experiments by other researchers have found actual examples of this phenomenon and have since named it quantum plasticity. Seeking to settle the matter once and for all, Chan and new partner Duk Kim redesigned the original experiment in a way that eliminated the possibility of bulk helium forming in a gap between the chamber and the helium-glass mixture. Doing so resulted in no increase in the rate of oscillation as the chamber was cooled. This result suggests that the increased oscillation rate of the earlier experiment was due to quantum plasticity, not the development of a helium supersolid. This new research doesn’t disprove theories regarding supersolids of course. Rather, it demonstrates that faulty research can sometimes lead to new discoveries such as, in this case, quantum plasticity.

Lett. 109, 155301 (2012) DOI: 10.1103/PhysRevLett.109.155301AbstractIn 2004, Kim and Chan carried out torsional oscillator measurements of solid helium confined in porous Vycor glass and found an abrupt drop in the resonant period below 200 mK. The period drop was interpreted as probable experimental evidence of nonclassical rotational inertia. This experiment sparked considerable activities in the studies of superfluidity in solid helium. More recent ultrasound and torsional oscillator studies, however, found evidence that shear modulus stiffening is responsible for at least a fraction of the period drop found in bulk solid helium samples. The experimental configuration of Kim and Chan makes it unavoidable to have a small amount of bulk solid inside the torsion cell containing the Vycor disk. We report here the results of a new helium in Vycor experiment with a design that is completely free from any bulk solid shear modulus stiffening effect. We found no measurable period drop that can be attributed to nonclassical rotational inertia.via Physics Focus (—Moses Chan, co-author of a paper published in 2004 describing work that resulted in claims of the discovery of supersolid helium, has now co-authored another paper, published in Physical Review Letters, describing flaws in his original research.

Alexander III, known more commonly as Alexander the Great was King of Macedon, a state that existed in northern ancient Greece. By the age of thirty he had built one of the largest empires of the ancient world, running from Egypt in the west, to the Indus River in the east. At the time of his birth, the city of Alexandria had not yet been built; he founded the city in 331 BC realizing its future importance as a shipping hub. Since that time, the city has become famous as the site of one of the seven wonders of the ancient world; it’s 400 foot lighthouse at the mouth of its harbor and as the home of Cleopatra and the Royal Library of Alexandria.The researchers write that aligning the city with Alexander’s birth date would have been a way to highlight the king’s power. They next plan to study other cities that were part of the ancient king’s empire to see if they can find other solar patterns.

Doing so revealed that it rose less than half of a degree off the route of the city’s main course. They also found that the “King’s Star” Regulus, located in the head of the constellation Leo, rose in a similar alignment.The researchers note that it was a common practice in ancient times to base architectural designs on astronomical events, pointing out that the Great Pyramid at Giza has been found to be aligned along compass points.

Anthropologist offers possible explanation for collapse of ancient city of Teotihuacan

first_img Citation: Anthropologist offers possible explanation for collapse of ancient city of Teotihuacan (2015, March 17) retrieved 18 August 2019 from ( —Linda Manzanilla, an anthropologist with Universidad Nacional Autónoma de México has published a paper in Proceedings of the National Academy of Sciences, offering a possible explanation for the collapse of the early central Mexican city of Teotihuacan—she believes it was due to clashes between groups with differing economic interests. The ruins of Teotihuacan can be seen today at a location approximately 30 miles northeast of modern Mexico City, and offer testament to the flourishing metropolis that once was home to approximately 125,000 people, making it the most populous city in the pre-Columbia Americas. The city got its start around 100 BCE, but was completely decimated by the eighth century. Why it collapsed has been a subject of debate among historians and anthropologists for several years. In this new effort, Manzanilla suggests it was not drought or invaders that brought down the great city, but internal strife among its inhabitants.Manzanilla is basing her claims on her examination of parts of the ruins, along with an analysis of human remains and other artifacts that have been found in the area. She suggests that because of volcanic eruptions in the first and fourth centuries, people were forced to move from the southern basin, and wound up in Teotihuacan, which resulted in a mix of ethnicities. Activity markers, nutritional patterns, isotopes and ancient DNA analysis showed that the immigrants (some of whom brought specialized skills along with them) tended to live on the outskirts of the city in different neighborhoods and were given specific jobs by businessmen that helped to bolster the economy. But it also led to rivalries between the neighborhoods. As time passed, she believes that tensions arose between wealthy businessmen, neighborhood leaders and those that were part of the government. The tension was increased, she claims, by the government insisting on retaining control of all natural resources. Eventually, that tension boiled over and the result was an angry mob of people burning down major parts (administration and ritual buildings) of the city and trashing sculptures and other iconic structures, and eventually to total collapse of the city.She reports that thus far, no evidence of a foreign invasion of any type has been found.

Manzanilla, PNAS, DOI: 10.1073/pnas.1419881112AbstractIn this paper, I address the case of a corporate society in Central Mexico. After volcanic eruptions triggered population displacements in the southern Basin of Mexico during the first and fourth centuries A.D., Teotihuacan became a multiethnic settlement. Groups from different backgrounds settled primarily on the periphery of the metropolis; nevertheless, around the core, intermediate elites actively fostered the movement of sumptuary goods and the arrival of workers from diverse homelands for a range of specialized tasks. Some of these skilled craftsmen acquired status and perhaps economic power as a result of the dynamic competition among neighborhoods to display the most lavish sumptuary goods, as well as to manufacture specific symbols of identity that distinguished one neighborhood from another, such as elaborate garments and headdresses. Cotton attire worn by the Teotihuacan elite may have been one of the goods that granted economic importance to neighborhood centers such as Teopancazco, a compound that displayed strong ties to the Gulf Coast where cotton cloth was made. The ruling elite controlled raw materials that came from afar whereas the intermediate elite may have been more active in providing other sumptuary goods: pigments, cosmetics, slate, greenstone, travertine, and foreign pottery. The contrast between the corporate organization at the base and top of Teotihuacan society and the exclusionary organization of the neighborhoods headed by the highly competitive intermediate elite introduced tensions that set the stage for Teotihuacan’s collapse.last_img read more

New stars discovered in the Rho Ophiuchi Dark Cloud

first_img Citation: New stars discovered in the Rho Ophiuchi Dark Cloud (2016, May 26) retrieved 18 August 2019 from More information: Rho Ophiuchi Dark Cloud is a dark nebula of gas and dust located some 460 light years away in the constellation of Ophiuchus, making it one of the closest stellar nurseries to our planet. This dense nest of stellar objects is a perfect target for astronomers to search for newborn baby stars.Recently, Pillitteri and his colleagues decided to conduct a detailed X-ray study of this cloud to track down possible newly born stars. They have analyzed the data provided by ESA’s XMM-Newton space observatory, which observed the multiple star system Rho Ophiuchi and its surroundings in August 2013. The spacecraft is able to conduct narrow- and broad-range spectroscopy and to perform simultaneous imaging of objects in both X-ray and optical wavelengths, enabling detailed studies of star-forming regions.Three European photon imaging cameras (EPIC) mounted on XMM-Newton allowed the scientists to detect dozens of X-ray sources, 22 of which turned out to be diskless class III young stars.”We detected 89 X-ray sources (…) Based on infrared and X-ray properties, we can distinguish between young stellar objects belonging to the cloud and background objects. Among the cloud members, we detect three debris disk objects and 22 diskless class III young stars,” the researchers wrote in the paper.According to the study, these stars belong to a small cluster born about five to 10 million years ago during a previous event of star formation just north of a dense core of the cloud, designated L1688. This core itself is believed to contain a stellar population of about 300 young stellar objects. The age of the cluster could be confirmed by the near absence of stars with disks. The scientists try to explain this absence: “We speculate that the densest part cloud was larger in the past and that a fraction of the stars have since migrated away from the cloud. What we observe now is the patchy ‘left-over’ cloud of a process of star formation that did not occur uniformly across the cloud,” the paper reads.The astronomers noted that a proper indication of the age of the stellar objects in Rho Ophiuchi Dark Cloud along with assessment of the ratio of stars without disks to stars still bearing a disk could be crucial to our understanding of star-forming processes in stellar nurseries. They endorse future X-ray observations of multi-core clouds, emphasizing that current motion studies and infrared observations are unsatisfactory for regions distant than 3,000 light years.”Proper motion studies have insufficient sensitivity, photometric selection is strongly contaminated by field stars, and spectroscopic selection requires an enormous effort to study hundreds or thousands of stars – even when using new multi-fiber facilities. Infrared studies are helpful (when crowding is not extreme), but they are sensitive only to stars with circumstellar material, bright in infrared, but insensitive to objects without disks, i.e., class III pre-main-sequence stars,” the scientists wrote. © 2016 Star-forming ring spotted around distant supergiant star Kappa Ori Main panel: composite RGB image of WISE images and X-rays.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Prior observation of the wildebeest in the wild has shown that the large animals migrate across parts of Africa looking for food and water. It is one of the few characteristics of the animals that draws attention. Normally they only make it into nature documentaries when they are eaten by other more photogenic animals. Some wildebeest herds have been found to travel as far as 1,900 kilometers—sometimes attracting tourists as they go. Perhaps just as remarkable, the animals do it during the heat of day, which can soar to over 38 degrees C. And until now, it was believed that the creatures, also known as gnu, needed to stop during such migrations each day to drink water. But the researchers with this new effort found that wildebeests can travel for up to five days without drinking any water at all. Curious as to how they could accomplish this feat, the researchers darted several specimens and took muscle tissue samples for study back in their lab.The researchers found that the muscle tissues were extremely efficient. Administering electric shocks while measuring the amount of heat released showed that approximately 62.6 percent of the energy used by the muscles went into muscle movement—just a third was lost as heat. The researchers point out that such high efficiency has only ever been surpassed by turtles. Most animals have muscles that are far less efficient, with an average of just 25 percent efficiency. A wildebeest wearing a RVC tracking collar. The black globe thermometer and humidity sensor can be seen on the left side. Credit: Professor Alan Wilson The researchers also point out that such high muscle efficiency is why the animals are able to walk so long without drinking—with less heat loss, less water is required for cooling. That means less is given off as evaporation, resulting in less need for drinking.The wildebeest is thus the largest animal to have its muscle efficiency measured directly, and offers a framework for studying other animals in the field as well.

Water nanodroplets zip across graphene faster than a cheetah

first_img Explore further The researchers, Ermioni Papadopoulou and Petros Koumoutsakos at ETH Zürich, Constantine M. Megaridis at the University of Illinois at Chicago, and Jens H. Walther at ETH Zürich and the Technical University of Denmark, have published a paper on the fast-moving water droplets in a recent issue of ACS Nano.”We can get very high-speed directed transport of water droplets on the nanoscale, without expending any energy but simply through the patterning of graphene,” Koumoutsakos told “This may have important applications in nano-fabrication and precise drug delivery. It also provides for the first time a simple quantitative explanation for the ultrafast transport of water at the nanoscale.”This nano-/microscale mode of transport is very different than anything observed on the macroscale. The graphene surface was structurally patterned to create wettability gradients, ranging from hydrophobic to hydrophilic. The water nanodroplets, each consisting of approximately 1500 water molecules, were then placed on the surface. The different surface patterns created large contact angles on the hydrophobic domains and smaller contact angles on the hydrophilic domains. The differences in the contact angles at the advancing and receding ends of the water droplets set the droplets in motion and accelerated them forward.Similar mechanisms are found in nature, such as on the surface of the Namib desert beetle and the vein network of banana leaves. These surfaces have patterns that result in the improved collection and transport of water. In experiments with the graphene, the researchers observed water droplet velocities on the order of 100 meters per second, which is two orders of magnitude faster than the highest velocities reported for water droplets propelled by certain other methods, such as surface energy gradients. As expected, smaller droplets move faster than larger ones due to the larger droplets’ increased inertia and greater friction with the surface.After analyzing the underlying mechanisms for the water transport, the researchers derived a scaling law and developed a model that can be used to predict droplet trajectories. This information can be used to design future devices for potential applications, such as high-efficiency drug delivery, electricity generation, and ultrafast heat dissipation for nano- and microscale systems. The researchers plan to further investigate high-speed water transport mechanisms in places other than graphene.”We are examining ultrafast transport of water in other nanostructures, such as carbon nanotubes,” Koumoutsakos said.

The water droplets’ ultrafast velocities don’t require any pump, but instead occur simply due to the geometric patterns on the graphene surface, which create different contact angles at the front and back of the moving droplets to propel them forward.

How to Make Your Teaching More Engaging

first_img Read the whole story: The Chronicle of Higher Education The psychologist Todd Kashdan writes, “If you want people to be interested, committed, and willing to devote effort to learning, mastering, and using these skills for the long haul, then you can’t avoid the initial step of stimulating excitement.” In short, if you really want a student like Alex to learn and succeed, something needs to happen first: You need to engage him. Alex can do all of that — but he could use your help. As his instructor, you can stimulate his curiosity with an inspiring and energizing presentation style, with activities and assignments that maximize his sense of control over the material, and with expertise that helps him reach just a bit beyond his current abilities. To have any hope of learning the material, Alex needs to actually involve himself in the course. He needs to direct his attention to the lecture and the problem sets. He must be willing to use his working memory to attempt solutions rather than daydream about his life outside the small windowless room full of equations. He needs to decide the information is important enough to commit to memory and then be motivated to grapple with it later, on his own time, to prepare for the exams. Consider a student in an introductory math class — let’s call him Alex. Alex had some unpleasant experiences with math in high school. When he got to college, he tested into a math course below the level that would count toward his general-education requirements. He is thus feeling wary about the semester, and resents having to “waste” expensive college credit on a course that he is unlikely to enjoy and that won’t get him any closer to his degree.last_img read more

It’s important to mention that setting up of fast track courts was in the election manifesto of all the political parties including BJP, Aam Aadmi Party and the Congress but nothing could materialise due to short lived AAP government followed by the President’s rule. “Besides, ensuring speedy justice in rape cases, the police patrolling must be increased and police reforms be introduced to handle the rape cases properly,” he added, expressing his concern on poor collection of evidences by the police.

KMC pulls down centuryold building in city

first_imgtKolkata: In a major move the Kolkata Municipal Corporation (KMC) on Wednesday pulled down a century-old “dangerous and dilapidated” building in Central Kolkata.The civic authorities had earlier identified the building as dilapidated and requested the residents to vacate the premises. But despite the KMC notice, the residents continued to stay in the house. It had also put up a notice in front of the house.KMC usually does not pull down old structures that are occupied on humanitarian grounds and requests the residents to repair them. But the requests only evoke lukewarm responses. Also Read – Heavy rain hits traffic, flightsThe residents continue to stay in the old houses and KMC is blamed when portions of these houses collapse. In 2017, as many as 22 people who used to live in old dilapidated and dangerous houses, had died.As monsoon poses a serious threat to these structures, the Building department of KMC had decided to demolish these houses. A KMC team led by the senior officials of the Building department and demolition workers began pulling down the old tenanted house on Rani Rashmoni Road. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe building, not repaired for the past 50 years or more, was occupied by tenants who pay monthly rent that vary between Rs 25 to Rs 50 per month. The owner said that it is not possible for him to repair the building with this amount.Senior civic officials said around 2,000 buildings have been identified, which are dangerous and dilapidated. The civic authorities have failed to identify the owners of some of these houses. “The problem lies with the houses where the ownership is not known. The tenants had trespassed the houses and are not paying any rent,” they said. On March 10, 2017, the Bengal Legislative Assembly had unanimously passed The Kolkata Municipal Corporation (Amendment) Bill, which gives KMC the power to auction a building, pull it down and construct a new one with proper rehabilitation of the tenants, where the owners have failed to repair the structures.KMC had put up billboards all over the city, requesting the owners of buildings that are more than 50 years old, to examine the health of the structures by an empanelled structural engineer. Senior civic officials said some owners of old buildings have shown interest in pulling down the houses with proper rehabilitation of the tenants.”We cannot allow inmates of old dilapidated buildings to die every year. We will continue to pull down these structures for the safety and security of the occupants of the adjacent buildings,” a senior civic official said.last_img read more

To combat these unexpected surprises, always carry a matte lipstick and a kohl pencil in your bag.* Matte lipstick: It’s a secret weapon that’s doing huge this season. There’s a shade in matte for everyone irrespective of your skin tone. So, lay your hands on a berry shade and make heads turn this party season. You can also play safe by keeping a red lippie in matte as it not just helps update an outfit, but also brightens up a tired face in an instant.  Also Read – Add new books to your shelf* Kohl pencil: Kohl highlighted eyes are classic and can never go wrong. Also, you can apply it as an eyeliner to refresh your look. Add a cool wing for that dramatic look.* Foundation: A foundation based moisturiser is your go-to when all you need to do is minimise the look of pores and add some amount of SPF protection to your skin. It’s a must for a pre-party complexion enhancement. * Blush or tint: If a blusher is too much to carry, then remember that your lip tint can also be used as a blush. Dab a little bit along the cheek bone and spread with your finger for those perfectly glowing cheeks.* Perfume: If you smell good, you automatically add to your killer looks. And if you don’t, then no amount of make-up can help. So, slip in a cool bottle of perfume in your bag and spread fragrance wherever you set foot.last_img read more

Enjoy Holi with care

first_imgHoli is marked with much fun and fervour throughout the country and other parts of the world. And while the festival brings much colour and joy into your life, skin and hair bear the brunt of it. That, however, does not mean that one should not celebrate the festival. And expert suggests that with some basics in place, one can look flawless even during the festival of colour. Below are some tips on how one can take care of hair, skin and nails during the assault of colours. Also Read – Add new books to your shelfDoes oiling your skin and hair really help?Definitely. The chemicals in the colour and the exposure to sun strip your skin and hair of their natural oils and moisture. Oil forms a protective barrier, keeps your skin nourished and makes it easy to get colour out. Especially tough to reach for cleaning are spots like ear lobes, belly button etc. So, apply two layers of oil to your body, and head out and enjoy some Holi fun without fear. How many times can I bathe in a day to get the colour out? Also Read – Over 2 hours screen time daily will make your kids impulsiveAfter Holi, your skin is already sensitive and has probably even reacted to the colours. In such a state you would not want to further strip your skin of its natural moisture, and alter its PH balance by bathing multiple times a day. Ideally, try not to bathe more than two times a day, unless absolutely necessary. Most importantly, ensure that you moisturise adequately each time. Is there any way to keep the colour out of my nails?Nails are porous in nature hence they tend to absorb a lot of color, which makes the Holi colour stain more prominent. Apply a layer of clear nail polish or any colour of your choice to prevent them from absorbing artificial colour. Does exfoliation help get rid of the colour quickly? Exfoliation is an abrasive activity, and when your skin is already dry, the process would do more harm than good. Any cleanser that has Sodium Laureth Sulfate in it, which is known to be a de-greaser and strips away colour, is a much better way to go about it, follow this up with a good moisturizer. So, the colour is out, but my skin and hair is still dull and dry, what do I do? Your skin regenerates and repairs itself at night, so it is the best time to restore essential nutrients, moisture and a natural glow to your skin. Invest in a good serum that can be applied before going to bed, and an overnight hair serum to restore the bounce to your tresses. You would be able to see results within two to four weeks depending on the products used. And it’s not just colours that harm you but also food so, don’t make Holi an excuse to binge on unhealthy calories and accumulate health risks. Go for detox and ditch too much of sweets.Eat right and combat overeating. Gujiya and papri among a dozen other dishes are a must, but you must maintain the calorie consumption. For instance, take a spoonful instead of a full serving.You can increase water intake and salads to curb your appetite. Drink at least eight glasses of water for keeping your body hydrated. Try to stay away from drinks such as thandai and other alcoholic beverages.Plan your meal in such a way that one special meal of the day should most likely be lunch, so that day activities and movements can burn the extra amount of calories. Try keeping your breakfast light and healthy while dinner should be as light as possible to manage the intake of calories.Don’t neglect your exercise routine, keep your body active and compensate for the extra calories that are consumed.Try some healthy snacks like roasted hare kabab, grilled paneer tikka, rawa idli, broccoli and lentil chaat.Make a smoothie of strawberries, raspberries, apple, grapes and fresh ripened tomatoes. Add a little water and serve chilled.last_img read more

Delving deep into human mind and soul

first_imgTaking inspiration from his spiritual lineage of Aghora and Tantra, Guru Bharat Thakur has organised his solo show ‘Prayag – The Inner Journey’ at Visual art gallery, India Habitat Centre. The exhibition which is open for public display from January 7-10, is showcasing three major bodies of work; his self-portraits, portraits of babas and sculptures.In his revelatory self-portrait series ‘Aham’, one can see the artist displaying an intense and piercing gaze inward, inspired by the paradigms of Aghora as well as Tantra. These portraits are realistic and draw the viewer in with their hyper-real likeness and the sheer force of the grotesque, which makes the viewer take a step back and introspect. Also Read – Add new books to your shelfIn this series, Bharat is delving deep into the human mind and soul to cull into the dark recesses to reveal what is yet unknown. In the paintings on the Aghori babas, Bharat’s intimacy with the subject and his unbridled passion and energy can be seen in his unique approach of form, colours, and textures. The collection reflects most of his turbulent and roller-coaster life which is about exploring different dimensions and how to bring about something that only a sculpture or an installation can achieve. In the ongoing exhibition, he is presenting a totally different kind of sculpture- kinetic structure. Being a multidimensional artist, Bharat experiments with sculpture, installations and a wide variety of painting mediums. Adding to his capabilities as an artist, no medium is too challenging and no subject is beyond contemplation for him.last_img read more

Defectors greedy and corrupt BJP collecting TMCs garbage Mamata

first_imgKolkata: Coming down heavily on TMC leaders who joined the BJP post the Lok Sabha elections, West Bengal Chief Minister Mamata Banerjee Tuesday called them “greedy and corrupt” and said the saffron party was “collecting garbage”. The Trinamool Congress (TMC) supremo also said she would be replacing the “traitors” with “dedicated members” and asked those “undecided about joining the BJP” to leave her party at the earliest. Banerjee’s remarks came in the backdrop of three MLAs and a majority of councillors from five municipalities in the state defecting to the BJP from the TMC since the declaration of general election results last month. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata “We are not bothered about a few corrupt and greedy leaders who are switching to some other party. They joined the BJP as they were afraid they might face consequences for their activities,” the chief minister said. She said her administration is contemplating action against those involved in corruption. “We are throwing out our garbage and the BJP is collecting it. But joining some other party won’t save anyone from corruption probe,” Banerjee said at an internal meeting of party councillors from across the state. Also Read – Lightning kills 8, injures 16 in state The TMC boss said she would want to restructure her party ahead of the 2021 West Bengal Assembly elections, while insisting that those who were in two minds about switching to the BJP should leave immediately. “I would like to urge those traitors who are still undecided on whether to join the BJP or stay in the TMC to leave the party. We don’t want such leaders and workers,” Banerjee said. “One person will leave and 500 more will be inducted in his or her place. We want to restructure our party and replace corrupt and greedy workers with dedicated cadres,” she added. Admitting that her party’s leadership made a few mistakes while dealing with old-timers and loyalists, the chief minister assured that the lapses would be taken care of. Referring to legislator Sunil Singh, who joined the BJP on Monday, Banerjee said it was a misjudgement on the part of the TMC to have given him a ticket for Noapara Assembly bypoll last year, overlooking the candidature of Manju Basu, wife of slain TMC leader Bikash Basu. She also instructed her party leaders and workers to increase their outreach activities. Banerjee warned party members against infighting as it “affects the implementation of government schemes”. “Work hard and work honestly to reach out to the masses. Don’t fall into the BJP’s trap. People are looking at us. Do remember that councillors play a very important role, they are the face of the party in their respective wards,” she said.last_img read more

Iron Age Chariot Burial Site Found – Complete with Horse and Rider

first_imgIn the second time in two years, an Iron Age chariot has been found buried in a Yorkshire community. The discovery was made in the town of Pocklington, England, at a construction site where more than 200 homes are being built. As of early October 2018, archaeologists are working to fully excavate the find. Media reports say that not only a chariot but also horse and human remains were discovered.Simon Usher, managing director at Persimmon Homes Yorkshire, said: “We can confirm that a significant archaeological discovery, featuring an Iron Age horse-drawn chariot, has been made at our development, The Mile in Pocklington. Careful excavation is ongoing by our archaeologists and a thorough investigation is in the process to date and detail the find.”View from Pocklington to Burnby Lane. Photo by Andy Beecroft CC BY-SA 2.0In a bizarre twist, 18 months ago, another Iron Age chariot was found, along with two horses, at a different construction site in Pocklington. Archaeology Arts reported in 2017: “The chariot was buried as part of a funerary practice that was not uncommon in the Iron Age. However, the horses were a rather surprising addition for archaeologists.”The Telegraph said that “the find of the remains dating back to 500 BC is the first of its kind in the last 200 years and one of only 26 chariots ever excavated in the UK.”Chariot burial, illustration.Archaeologists say it is highly unusual for a horse and chariot to be buried together and with a human. In 2017, Paula Ware, managing director at MAP Archaeological Practice Ltd, told a reporter, “The chariot was located in the final square barrow to be excavated and on the periphery of the cemetery.”She continued, “The discoveries are set to widen our understanding of the Arras (Middle Iron Age) culture and the dating of artifacts to secure contexts is exceptional.”Bronze snaffle bit from the King’s Barrow burial in Yorkshire, now in the British Museum.

Photo by Ealdgyth CC BY-SA 3.0A chariot was the possession of a high-status individual. The rite of including horses as part of the burial is being puzzled over by researchers. Before finding the chariot, the dig at the Burnby Lane site revealed artifacts including a sword, shield, spears, brooches, and pots. The excavations give insight into life over 2,500 years ago. These are thought to be people of the Arras culture.Related Video: Artist Brings Animal Skulls To Life With Celtic EngravingsYorkshire continues to be the place where astoundingly well-preserved remains of the Arras culture are found. In 2016, some 150 skeletons and their personal possessions were discovered in a small market town at the foot of the Yorkshire Wolds.Illustration of a chariot burial.Some of the 75 square barrows, or burial chambers, contained personal possessions such as jewelry and weapons, according to The Guardian. Archaeologists also discovered a skeleton with a shield.Media reports say those remains were of a man in his late teens or twenties, who died with his sword at his side. Before his death he reportedly had six spears pressed into him “like a hedgehog.”It is believed these sites all date to the Iron Age, which in Britain lasted from 800 BC until the time of the Roman conquest, beginning in 43 AD.An in-depth study will focus on whether the population is indigenous or were recent arrivals from the Continent. Archaeologists also hope to reveal how those buried at the site died and whether or not they are related in anyway, as well as potential DNA analysis.Read another story from us: Identity Finally Revealed of the Mysterious ‘Woman in the Iron Coffin’The custom of burying the deceased with their chariots within squares is unknown in the rest of the British Iron Age.

Dont Look Down Harrowing Photos of Early HighRise Workers Way Up in

first_imgIn the early 20th century, a construction boom took hold in large cities of the U.S. such as New York and Chicago. Gigantic skyscrapers were erected from the ground up, demonstrating the lavish economic power of American industrialists who were literally competing with each other in terms of who could build the highest building in the city. Racing to the sky, these magnates often overlooked the safety of their workers, who would die by the dozen during construction. It was once estimated that for every $1 million spent on a construction site, a worker would lose his life due to an accident.A photograph of a cable worker, taken by Lewis Hine as part of his project.A worker at the edge of a platform, looking north.Atop the Empire State – in construction – Chrysler Bldg & [Daily] News in middle foreground.A construction worker on the Empire State Building.There were no helmets involved and rarely any safety ropes, thus the construction workers were left on their own to overcome severe issues of vertigo and other problems that came when working sometimes up to 1,250 feet (380 m) off the ground. As one work foreman famously stated:“Building skyscrapers is the nearest peace-time equivalent of war.”Empire State Building construction, photographed by Lewis Hine.Empire State Building construction, photographed by Lewis Hine.Painters working on the bridge, October 1914, photograph taken by Eugene de Salignac.However, while the workers faced death on a daily basis, over time many of them became comfortable with the idea of working in such a dangerous environment. Their lifestyle soon came into the spotlight, with reports being written and photos often snapped, capturing the horror and glory of the skyscraper construction worker.Nicknamed “Cowboys of the skies” by the press, these daredevils were glad to risk their lives for a photograph or two in the newspapers. This was how a number of unnerving pictures were created, in which these “cowboys” seem to defy gravity itself, while certainly defying their fears and testing their balance.‘Raising the Mast, Empire State Building,’ photograph, silver print, by the American photographer Lewis W.

We can still marvel at these daredevils through photographs that captured them casually strolling the skeletal structures of future skyscrapers, or even ordering a meal on the tenth floor of the unfinished Waldorf Astoria, delivered by two equally brave bow tie and jacket-clad waiters.last_img read more
