Electric vehicle travels recordbreaking 623 miles on a single charge

first_img © 2010 PhysOrg.com 300 mph: New Land Speed Record for a Hydrogen Powered Vehicle The Tokyo-based Japan Electric Vehicle Club, a group of electric vehicle enthusiasts, converted the Daihatsu Mira EV from gas to electric using Sanyo lithium-ion batteries. The record-breaking run took place at the track of a training school for auto racers in Shimotsuma, Ibaraki. Seventeen drivers took turns driving the electric vehicle during a time period of 27.5 hours, with the car traveling at an average speed of 25 mph (40 kph).The Mira EV was powered by an assembly of 8,320 cylindrical lithium-ion batteries (Sanyo No. 18650) that are normally used in laptops and other electronic devices. According to a press release, the battery configuration was similar to the one used to set the previous record.

Decoding cosmological data could shed light on neutrinos modified gravity

This Hubble Ultra-Deep Field image of the distant universe contains approximately 10,000 galaxies. Image credit: NASA and the ESA (PhysOrg.com) — Today’s most powerful telescopes collect huge amounts of data from the most distant locations of the universe – yet much of the information is simply discarded because it involves small length scales that are difficult to model. In an effort to waste less data from cosmological surveys, a team of scientists has developed a new technique that allows researchers to use otherwise unusable data by “clipping” some of the highest density peaks, which present the greatest challenge to models. This data could provide a way to address some unsolved problems in physics, including estimating the neutrino mass and investigating theories of modified gravity. The scientists, Fergus Simpson, Alan Heavens, and Catherine Heymans from the University of Edinburgh, and J. Berian James from the Dark Cosmology Centre in Copenhagen, Denmark, and the University of California, Berkeley, have published their study in a recent issue of Physical Review Letters.“The pattern formed by galaxies in our Universe is often referred to as the cosmic web, as it bears some resemblance to the structures seen in an intricate spider web,” Simpson told PhysOrg.com. “Within the detailed nature of this pattern is encoded various pieces of information regarding the composition of the Universe, the conditions in the early Universe, and the laws of gravity. However, when we try to study the fine detail on ‘small’ scales (around 100 million light years or less), it appears to be very unpredictable since the Universe is particularly lumpy on these scales, so the physics becomes very complex and nonlinear. In other words, we don’t know how to decode that information, and it’s particularly frustrating since most of the useful information is buried in these smaller scales.”In an attempt to decode this small-scale data, the researchers developed the density “clipping” technique, which makes the data accessible to modeling.“By applying a simple correction to the very densest regions of a simulated patch of the Universe, just 0.1% of the volume, we found that this removes most of this unpredictable behavior,” Simpson said. “We have now demonstrated that a great deal of information from these smaller scales can be successfully extracted.”He explained that this extra data could prove useful for scientists studying a wide range of areas, such as calculating a better estimate of the neutrino mass.“It is these ‘small’ cosmological scales that neutrinos are thought to have influenced in the early Universe, at a time when they were travelling very close to the speed of light,” he said. “The extent of their influence depends on how much time they spent at these very high speeds, which in turn is determined by their mass. So it’s possible that our technique will allow the neutrino masses to be determined from the distribution of galaxies.“Neutrinos can tell us about fundamental physics as well as cosmology. In the Standard Model of particle physics, neutrinos do not have mass, so neutrino masses tell us about extensions of the Standard Model. In principle, measurements from cosmology can be significantly more precise than laboratory experiments.”In addition, the small-scale data enables researchers to better understand the relationship between galaxies and dark matter, which could potential lead to methods for investigating theories of modified gravity with observations.“The discovery that the expansion of the Universe is accelerating has led many cosmologists to wonder if this is an indication that the laws of gravity need to be modified,” Simpson said. “If there is some new gravitational physics, it is expected to change the rate at which dark matter clusters together. A major difficulty in measuring the dark matter’s behavior is that we don’t know how the distribution of galaxies (which is what we can measure directly) relates to the distribution of dark matter. In our study we demonstrated that our technique allows the relationship between galaxies and dark matter (‘galaxy bias’) to be determined with much greater accuracy. Once the galaxy bias is known, we can determine how fast the dark matter has been clustering, and see whether that matches our expectation from Einstein’s laws of gravity.”center_img Andromeda dwarf galaxies help unravel the mysteries of dark matter Journal information: Physical Review Letters This document is subject to copyright.

Physicists find quantum coherence and quantum entanglement are two sides of the

first_img More information: Alexander Streltsov, et al. “Measuring Quantum Coherence with Entanglement.” Physical Review Letters. To be published.Also at arXiv:1502.05876 [quant-ph] Journal information: Physical Review Letters Close relatives with the same rootsAlthough physicists have known that coherence and entanglement are close relatives, the exact relationship between the two resources has not been clear. It’s well-known that quantum coherence and quantum entanglement are both rooted in the superposition principle—the phenomenon in which a single quantum state simultaneously consists of multiple states—but in different ways. Quantum coherence deals with the idea that all objects have wave-like properties. If an object’s wave-like nature is split in two, then the two waves may coherently interfere with each other in such a way as to form a single state that is a superposition of the two states. This concept of superposition is famously represented by Schrödinger’s cat, which is both dead and alive at the same time when in its coherent state inside a closed box. Coherence also lies at the heart of quantum computing, in which a qubit is in a superposition of the “0” and “1” states, resulting in a speed-up over various classical algorithms. When such a state experiences decoherence, however, all of its quantumness is typically lost and the advantage vanishes.The second phenomenon, quantum entanglement, also involves superposition. But in this case, the states in a superposition are the shared states of two entangled particles rather than those of the two split waves of a single particle. The intrigue of entanglement lies in the fact that the two entangled particles are so intimately correlated that a measurement on one particle instantly affects the other particle, even when separated by a large distance. Like coherence, quantum entanglement also plays an essential role in quantum technologies, such as quantum teleportation, quantum cryptography, and super dense coding. Converting one to the otherIn a paper to be published in Physical Review Letters, physicists led by Gerardo Adesso, Associate Professor at the University of Nottingham in the UK, with coauthors from Spain and India, have provided a simple yet powerful answer to the question of how these two resources are related: the scientists show that coherence and entanglement are quantitatively, or operationally, equivalent, based on their behavior arising from their respective resource theories. © 2015 Phys.org Explore further Physicists show ‘quantum freezing phenomenon’ is universal This document is subject to copyright. 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. The physicists arrived at this result by showing that, in general, any nonzero amount of coherence in a system can be converted into an equal amount of entanglement between that system and another initially incoherent one. This discovery of the conversion between coherence and entanglement has several important implications. For one, it means that quantum coherence can be measured through entanglement. Consequently, all of the comprehensive knowledge that researchers have obtained about entanglement can now be directly applied to coherence, which in general is not nearly as well-researched (outside of the area of quantum optics). For example, the new knowledge has already allowed the physicists to settle an important open question concerning the geometric measure of coherence: since the geometric measure of entanglement is a “full convex monotone,” the same can be said of the associated coherence measure. As the scientists explained, this is possible because the new results allowed them to define and quantify one resource in terms of the other.”The significance of our work lies in the fact that we prove the close relation between entanglement and coherence not only qualitatively, but on a quantitative level,” coauthor Alex Streltsov, of ICFO-The Institute of Photonic Sciences in Barcelona, told Phys.org. “More precisely, we show that any quantifier of entanglement gives rise to a quantifier of coherence. This concept allowed us to prove that the geometric measure of coherence is a valid coherence quantifier, thus answering a question left open in several previous works.”While the results show that coherence and entanglement are operationally equivalent, the physicists explain that this doesn’t mean that are the exact same thing, as they are still conceptually different ideas. “Despite having the same roots of origin, namely quantum superposition, coherence and entanglement are conceptually different,” said coauthors Uttam Singh, Himadri Dhar, and Manabendra Bera at the Harish-Chandra Research Institute in Allahabad, India. “For example, coherence can be present in single quantum systems, where entanglement is not well-defined. Also, coherence is defined with respect to a given basis, while entanglement is invariant under local basis changes. In all, we believe coherence and entanglement are operationally equivalent but conceptually different.” Future quantum connectionsThe operational equivalence of coherence and entanglement will likely have a far-reaching impact on areas ranging from quantum information theory to more nascent fields such as quantum biology and nanoscale thermodynamics. In the future, the physicists plan to investigate whether coherence and entanglement might also be interconverted into a third resource—that of quantum discord, which, like entanglement, is another type of quantum correlation between two systems.”Our future plans are diverse,” Adesso said. “On the theoretical side, we are working to construct a unified framework to interpret, classify and quantify all different forms of quantum resources, including and beyond entanglement and coherence, and highlight the interlinks among them from an operational perspective. This will allow us to navigate the hierarchy of quantumness indicators in composite systems with a common pilot, and to appreciate which particular ingredients are needed in various informational tasks. “On the practical side, we are investigating experimentally friendly schemes to detect, quantify, and preserve coherence, entanglement and other quantum correlations in noisy environments. More fundamentally, we hope these results will inspire us to devise scalable and efficient methods to convert between different quantum resources for technological applications, and bring us closer to understanding where the boundaries of the quantum world ultimately lie in realistic scenarios.” (a) Input states that are fully incoherent (S and A) cannot be converted to entanglement via incoherent operations. (b) On the other hand, when the input state of S has any nonzero coherence, the coherence can be converted to entanglement via incoherent operations. The new results show that, in such a scenario, the input coherence and the output entanglement are quantitatively equivalent. Credit: Streltsov, et al.

This finding allows physicists to apply decades of research on entanglement to the more fundamental but less-well-researched concept of coherence, offering the possibility of advancing a wide range of quantum technologies.last_img read more

Researchers use new approach to create triangulene molecule

first_img A triangulene molecule, as its name suggests, is a hydrocarbon molecule that is shaped like a triangle—it is also flat because it is just one atom thick—chemists have been trying in vain for years to synthesize such molecules because of their expected unique properties, but have failed due to the instability of unpaired electrons. In this new effort, the researchers took a new approach, using a scanning probe microscope tip to nudge pieces into place and then to tear away the parts that were not needed.To create the molecule, the researches began with a dihydrotriangulene molecule because it did not have the reactive unpaired electrons—they used it as a precursor, laying it on a base (they tried xenon, copper and salt) and then probing it with the electron microscope tip to get the molecules to align in the desired way. Next, they fired an electron beam at the molecule two times to remove the hydrogen, leaving behind a triangulene. The team then created an image of the molecule they had created using the same microscope, which showed its unique triangular shape. They also found they were able to keep the molecule stable as long as they kept it in a vacuum at low temperatures. In testing the molecule, they found that its two unpaired electrons had aligned spins, which was expected. That property was one of the reasons that chemists have been trying to synthesize the molecule—it is believed it could prove very useful in various electronic devices and might even have applications in a quantum computer.The research team plans to continue their work with creating triangulene molecules to learn more about their properties and possible uses. They also hope to find out why their technique worked when a copper bases was used—they thought the two materials would react. © 2017 Phys.org More information: Niko Pavliček et al. Synthesis and characterization of triangulene, Nature Nanotechnology (2017). DOI: 10.1038/nnano.2016.305AbstractTriangulene, the smallest triplet-ground-state polybenzenoid (also known as Clar’s hydrocarbon), has been an enigmatic molecule ever since its existence was first hypothesized. Despite containing an even number of carbons (22, in six fused benzene rings), it is not possible to draw Kekulé-style resonant structures for the whole molecule: any attempt results in two unpaired valence electrons. Synthesis and characterization of unsubstituted triangulene has not been achieved because of its extreme reactivity, although the addition of substituents has allowed the stabilization and synthesis of the triangulene core and verification of the triplet ground state via electron paramagnetic resonance measurements. Here we show the on-surface generation of unsubstituted triangulene that consists of six fused benzene rings. The tip of a combined scanning tunnelling and atomic force microscope (STM/AFM) was used to dehydrogenate precursor molecules. STM measurements in combination with density functional theory (DFT) calculations confirmed that triangulene keeps its free-molecule properties on the surface, whereas AFM measurements resolved its planar, threefold symmetric molecular structure. The unique topology of such non-Kekulé hydrocarbons results in open-shell π-conjugated graphene fragments6 that give rise to high-spin ground states, potentially useful in organic spintronic devices. Our generation method renders manifold experiments possible to investigate triangulene and related open-shell fragments at the single-molecule level.

Xray burst spotted in the galactic bulge

first_img Explore further (Phys.org)—Using the JEM-X telescope onboard the INTEGRAL space observatory, astronomers have discovered a new X-ray burst in the galactic bulge. The X-ray burst was detected from the faint unidentified transient source know as IGR J17445-2747. The discovery is reported in a paper published Sept. 8 on arXiv.org. First detected in 2003 by the IBIS/ISGRI gamma-ray telescope, IGR J17445-2747 was initially classified as a faint, unidentified persistent source. Subsequent observations of this source were conducted with the aim of detecting any outbursts that could be helpful in determining its nature. However, no such outbursts were discovered to date.This situation changed in April 2017 when a team of Russian astronomers from the Space Research Institute in Moscow spotted a type I X-ray burst from IGR J17445-2747. The group, led by Ilya Mereminskiy, discovered the burst by analyzing the data obtained during scanning observations of the galactic center region with the Joint European X-ray Monitor (JEM-X) telescope onboard ESA’s INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) space mission. “We reported the detection of a type I X-ray burst from the poorly studied transient X-ray source IGR J17445-2747 in the galactic bulge,” the researchers wrote in the paper.X-ray bursts are among the most energetic events observed in the universe. They are believed to be thermonuclear explosions occurring near the surface of accreting neutron stars. Such events occur in low-mass X-ray binary systems where a neutron star and low-mass main sequence star are in orbit around one another.Astronomers divide X-ray bursts into two categories: type I and type II. Type I bursts have a sharp rise followed by a slow and gradual decline of the luminosity profile, while type II bursts are characterized by a quick pulse shape, and may have many fast bursts separated by minutes. First X-ray burst was discovered in 1975 and so far, almost all of the detected X-ray bursts were found to be of type I.New observations from the JEM-X instrument show that IGR J17445-2747 is another source exhibiting type I X-ray bursts. The newly detected burst has a shape typical for type I bursts, including a fast rise shorter than five seconds and a much slower decay lasting about 15 seconds. The findings indicate that IGR J17445-2747 is an accreting neutron star with a weak magnetic field in a low-mass X-ray binary.”Such bursts are a sign of a thermonuclear explosion of accreted matter on the surface of a neutron star with a weak magnetic field in a low-mass X-ray binary. This is also confirmed by the almost blackbody spectrum detected during the burst,” the paper reads.Furthermore, few days after the discovery of the burst from IGR J17445-2747, the source was observed with the X-Ray Telescope (XRT) onboard NASA’s Swift Gamma-Ray Burst Mission in order to estimate its accurate position. These observations allowed the researchers to determine that IGR J17445-2747 is most likely located in the galactic bulge, between 16,300 and 40,000 light years away from the Earth.

New scanning technique allows researchers to read words on mummy waste wrap

first_imgCredit: CC0 Public Domain A team of researchers with University College London has found a noninvasive way to read writing on ancient papyrus used to construct boxes that held mummies inside their tombs. Team lead Adam Gibson spoke to the press about the new development and why he believes archaeologists and historians will find it useful. ‘Oldest’ papyrus is finally decoded Citation: New scanning technique allows researchers to read words on mummy waste wrap (2018, January 3) retrieved 18 August 2019 from https://phys.org/news/2018-01-scanning-technique-words-mummy.html Researchers have known for many years that workers in ancient Egypt recycled papyrus for different purposes—one particular use was creating decorated boxes into which mummies were placed. Papyrus scraps were glued together using paste and plaster, similar to modern paper-mâché projects. In ancient times, papyrus was used as a type of paper. Tax records were reported on papyrus, for example, as were lists of grocery items. Because papyrus was used for such mundane tasks, examples offer a glimpse of daily life in ancient civilizations such as that in early Egypt. Unfortunately, up till now, the only way to read such information on the recycled papyrus used to create mummy cases was to tear apart the fragments, destroying the box. In this new effort, the researchers have found a way to read the papyrus without causing it any harm.The technique involved using a digital imaging method that interpreted light bounced back from a subject. Prior research had shown that the pigment in ink used by the ancient Egyptians over 2000 years ago could fluoresce under the proper infrared filter. By using such filters with digital imaging technology, the team was able to see the ink and read what it said. The team used the technique on a coffin lid held at Chiddington Castle in Kent and report that they were able to make out a word that after translation spelled “Irethoreru,” which, the team explained, means “The eye of Horus is against them.” It was a common name in ancient Egypt. The team further suggests that because of the way the text was displayed on the papyrus, it was likely the mummy’s actual name.Gibson suggested that moving forward, researchers can use the technique to read other papyrus samples without destroying them in the process.center_img © 2018 Phys.org Explore further This document is subject to copyright.

Samuels opts out as WI players retain lawyers for battle ahead

first_imgWest Indies players who controversially abandoned the tour of India last week have retained legal counsel as they prepare to tackle the contentious Collective Bargaining Agreement signed by their union, West Indies Players’ Association (WIPA), but batsman Marlon Samuels has opted not to pursue this course of action along with his team-mates. This was confirmed in a release on Friday by ODI captain Dwayne Bravo, who is also acting as a spokesman for the aggrieved players, reports CMC. Samuels said earlier this week he was not supportive on the decision to abandon the tour and had hardly attended any of the players meetings on the troubled tour.  Also Read – Khel Ratna for Deepa and Bajrang, Arjuna for JadejaHowever, Bravo rebutted Samuels’ claims, contending the Jamaican right-hander was a vocal part of the meetings held. ‘I note the comments attributed to Mr. Marlon Samuels from media reports and wish to state that Mr. Samuels was invited to and did attend the majority of meetings with the players on tour,’ Bravo said. ‘We extended an invitation to Mr. Marlon Samuels with the full knowledge that he is not a member of WIPA but was an interested party. Mr. Samuels contributed vigorously to the discussions held and indicated clearly, at that time, that he would stand with any decision taken by the team. I am therefore shocked to see the statements, if true, that have been attributed to Mr. Samuels.’ Bravo stressed that while he had undertaken the role of spokesman for the players, all correspondence during that period had been issued with the full backing of the players. The senior all-rounder said the playing group had been boosted by the widespread support they had received, though they had also received criticism in some quarters.  Also Read – Endeavour is to facilitate smooth transition: Shastri‘We recognise that a few have attempted to put the blame squarely on the players without the full knowledge of the facts. This is regrettable since a few persons are making statements without knowing all the relevant facts. In time we believe all the facts will come to light. We do not wish to make any further statements on this matter since the players on tour (except Mr. Samuels) with some additional players who did not tour India have appointed Counsel to represent them in this matter,’ Bravo said.last_img read more

Walkers should have right of way

first_imgAman (in Hindi and Urdu) means peace. However, a 10-year-old Aman was recently crushed to death in south Delhi by a maverick DTC driver, when he was walking on a zebra crossing. Every day, scores of pedestrians, young and old, are hit like pin balls across the country by incompetent, arrogant, and rogue vehicle drivers.  It is the same chaotic scene on every street in every city. Pedestrians scurry to cross roads as vehicles relentlessly race ahead at maddening speeds with scant regard for the vulnerable humans in the way. Crossing main arteries, boulevards and streets in residential areas is always risky, particularly for children and senior citizens. Vehicles, especially two-wheelers, may zoom in from nowhere. Walkers account for nearly 50 per cent of all fatalities on Indian roads. Also Read – Gateway of criminal justice Each day is an obstacle race for pedestrians. During monsoon, the game turns into hop, step, and jump. In most urban settings, sidewalks do not exist, and where they do, they are in a poor state of repair with crevices and pits making it difficult to navigate on foot. They are poorly designed and challengingly high, making climbing and descending painful, particularly for children, women, the aged, and the physically challenged. At many places, pavements are covered-up drains with manholes, at times left. During rains, unless careful, walkers may vanish into these death traps. Therefore, pedestrians are forced to walk on road shoulders. Also Read – Turning a blind eye Pedestrians compulsorily share their right of way with utilities, trees, streetlights, transformers, markers for gas and electricity feeder boxes, signboards, roadside vendors, and bus shelters. Dogs and cattle dirty them. Footpaths are converted into makeshift markets. Not to be outdone, bikers climb up to exhibit acrobatics.  The latest to join these trappings are the 4G high mast towers on traffic islands, which serve as crossroads and where traffic signals are installed, in Nagpur. These towers have created blind spots that block the view of motorists. Planners and engineers are yet to properly design and construct walkable pavements. Amid all this chaos, hapless traffic cops have no role to play.  Crossing roads any given time is a nightmare for pedestrians. Zebra crossings are haphazard, traffic lights are installed at will—the poles have varying heights and designs, some are hidden behind adjacent trees planted on the meridian or are hidden by billboards hung on poles. In such a scenario jay walking is the order of the day. Pedestrians mostly ignore foot over bridges, skywalks, and subways as most are badly designed and ill maintained. Underground passages stink, are poorly-lit, appear unsafe and are difficult to access.   Every day, a competition ensues on Indian roads. For motorised vehicle drivers, the motto is “you don’t stop for anyone”. And more determinedly, these vehicles do not stop for walkers. Unrelentingly, resolute walkers also do not stop for cars. The end is predictable, and both the pedestrians and drivers are to be blamed. A major share in the blame certainly goes to the Government, civic authorities, city planners and law enforcement officers for the haphazard management of road safety. Passenger-vehicle conflict requires a judicious mix of road engineering and strict law enforcement measures. Pedestrians are also responsible, though less, for accidents. While population has exploded, necessary infrastructure has not kept pace. Many innovative devices could be installed, and maintained to control traffic and avoid conflict. Radar speed signs (an interactive sign generally comprising LEDs) that display vehicle speed as motorists approach, warn drivers to slow their vehicles when they are driving at unsafe speeds. Mounted on poles and powered by a solar panel, these devices must be used in school zones, busy residential roads, construction zones, and definitely on highways. Currently, interceptors are placed inside traffic police patrol vans, but they are too insignificant. Initially, the devices should be placed along with CCTVs where traffic violations are high.CCTVs must be installed at/near all intersections and record red light infractions, rolling through stop signs and halting on zebra crossings by vehicles must be recorded and sent to central computers. A major hindrance to pedestrians is vehicles parked haphazardly.  As followed in several countries, traffic wardens should issue tickets, using hand-held computerised devices, by pasting them on windshields of these vehicles. Walking is a basic and common mode of transport the world over. But, walkers are the most abused in India. Due to the dramatic growth of motor vehicles and general neglect of pedestrian needs in roadway design and land-use planning, pedestrians are increasingly vulnerable to road traffic injury. Pedestrian safety is a shared responsibility. All road users have a role to play in  protecting the pedestrians better and making cities safe for walking–-even for pedestrians. Perhaps, to help both in India, a car maker in the US has introduced a new driver-assist vehicle safety system that can reduce the severity of or even eliminate some frontal collisions involving vehicles and pedestrians. The Pre-Collision Assist with Pedestrian Detection, debuting this year in Europe, provides a collision warning to the driver. And, if the driver does not respond in time, the system can automatically apply the vehicle brake, to help reduce the severity of or even eliminate some frontal collisions. It uses radar and camera technology to scan the roadway ahead.(The author is an independent journalist)last_img read more

Life through her lenses

first_imgOne winter morning in 2013, when filmmaker Chitvan Gill, witnessed a grim patch of land turning overnight into a Kashmiri shantytown, she assumed the migration resulted from yet another turbulence in the valley.“I used to go to this area in East Delhi very often and suddenly out of the blue one morning, I come across a camp, just overnight. With the ongoing unrest in Kashmir in 2013, I thought it had got something to do with that. They must have fled their homes,” said Gill. Also Read – ‘Playing Jojo was emotionally exhausting’But, as she delved deeper into their homes, stories unfurled breaking stereotypes associated with the lives of those hailing from Jammu and Kashmir.Gill has captured their stories and way of life that has endured unnoticed in hidden corners of the national capital, in her two-day photo exhibition, Winterlude: A season in Delhi held at Alliance Francaise de Delhi.“When I started enquiring, I realised there’s nothing to do with any trouble, there’s nothing to do with any terrorism,” she says. Also Read – Leslie doing new comedy special with Netflix“This was a journey that thousands of impoverished peasants and farmers of Kashmir have been making to Delhi for more than four decades.

Almost like an oxymoron, gleaming faces of children with cracked cheeks, running noses and greased limbs, running amidst squalor, were recurrent in Gill’s exhibition.“The children were what was most remarkable about the camp. You forgot the filth and acid smoke and were drawn into their sheer joy, their laughter. Oblivious to the ugliness and degradation, it is a carnival, a time of unbridled exuberance and play for them,” said Gill. Gill says she has captured them in some of the most ordinary postures, but the freshness in expression, makes the pictures stand out.Other pictures document several aspects of their daily lives, from setting up their hutments, to their means of survival.“Stakes are driven into the ground, bamboo poles and splints form flimsy scaffoldings, blanketed over by bright sheets of tarpaulin,” she added.Hailing from an agricultural background, most of them, she says, “live off their earnings from their seven months in the valley, while a few engage in the uncanny business of ‘chanda’ collection.” The exhibition was an outcome of Gill’s photographing in East Delhi over a span of two winters, of 2013 and 2014.“Both the years, they came much later due to floods and elections,” she said.“While they were very happy being photographed, there was an evident ‘worriness’ about coming out into the open, for the obvious reason of being associated with violence,” she says vindicating why she has deliberately refrained from mentioning the exact location of the settlement.last_img read more
