Citation: Souping Up Superfluidity Calculations (2006, March 2) retrieved 18 August 2019 from https://phys.org/news/2006-03-souping-superfluidity.html “In quantum mechanics, very seldom do you solve exactly problems involving more than one particle,” explains Massimo Boninsegni, Canada Research Chair at the University of Alberta. Boninsegni and his colleagues, Nikolay Prokof’ev and Boris Svistunov, both at the University of Massachusetts, have found a way to work with quantum systems involving many interacting particles on a scale larger than ever attained before. Their creation, named worm algorithm, is a new approach to path integral Monte Carlo (PIMC) simulations, the only known exact general method in quantum mechanics. Superfluidity is among the most spectacular manifestations regarding the quantum behavior of matter on a macroscopic scale. Superfluids are liquids capable of flowing without resistance, a fascinating phenomenon not yet fully understood. In 2004, another state of particles on the quantum level, supersolids, was discovered. Supersolids act like superfluids (moving without resistance), but maintain the characteristics of crystalline solids. PIMC is the only known method that can afford the theoretical study of superfluidity, by allowing the simulation, on a computer, of realistic models of superfluids, and by providing exact estimates of key physical quantities, such as the superfluid density. This is where Boninsegni, Prokof’ev, and Svistunov come in. In a letter published in Physical Review Letters on February 23, they explain how their worm algorithm overcomes some of the limitations of PIMC, while still making use of its basic ideas. “If you look at what people were doing by PIMC last year, they were working with the same system sizes as 20 years ago,” Boninsegni tells PhysOrg.com. “It seemed impossible to go bigger. The fundamental approach had to be revisited.” Now, he says, it is possible to have results for systems with 100 times more particles, obtaining more accurate predictions for experimentally measurable quantities such as the superfluid transition temperature. Boninsegni continues, “If it was just about getting more accurate numbers, though, I wouldn’t be so excited. We’ve made it possible to do things that seemed out of reach just a year ago.”Some of these things include getting a better understanding of defects in solids or the presences of interfaces between two crystalline samples. In order to do that, it is necessary to have a model of a system large enough to show the complex interactions between many particles, and still have particles left over for the interface. The worm algorithm works by creating entanglement among the particles. This done by “cutting” particles, which Boninsegni explains are “much like strings or polymers that wiggle all over the place.” The polymer-like particles break up and reconnect with other particles in the system. The worm algorithm allows the particle ends to grow and shrink along a fictitious (“imaginary’’) timeline. They connect with and disconnect from other particles, but eventually the two loose ends reconnect. By the time the cut polymer finds itself back together, it has created a large permutation cycle. These cycles are crucial to capture the physics of superfluids. The algorithm was originally applied by Prokof’ev and Svistunov to lattice models of space. But a new set of research possibilities (including discovering a possible “superglass” state, in addition to the supersolid state) has emerged from the fact that this particular project has extended the worm algorithm to continuous space, and not just discrete space.Boninsegni explains that this is not a method of creating a “worm hole,” but rather a mathematical calculation that can better help us understand the underpinnings of our universe. Being able to work with multiple particles and larger, complex systems will open new doors into the possibilities presented by quantum mechanics.

(PhysOrg.com) — When light passes through materials that we consider opaque, such as paint, biological tissue, fabric and paper, it is scattered in such a complex way that an image does not come through. “It is possible to see the light, but not the information,” Sylvain Gigan tells PhysOrg.com. “We wanted to create a way to see the information through opaque media.” Citation: ‘Seeing’ through paint (2010, March 18) retrieved 18 August 2019 from https://phys.org/news/2010-03-seeing-through-paint.html More information: Popff, et. al., “Measuring the Transmission Matrix in Optics: An Approach to the Study and Control of Light Propagation in Disordered Media,” Physical Review Letters (2010).

Explore further How to see through opaque materials Gigan is a scientist at the City of Paris Industrial Physics and Chemistry Higher Educational Institute (ESPCI). Gigan worked in a group with Popoff, Lerosey, Carminati, Fink and Boccara to create an experiment that demonstrates that it is possible to construct a transmission matrix that allows them to “see” through some opaque materials. The results of their experiment are described in Physical Review Letters: “Measuring the Transmission Matrix in Optics: An Approach to the Study and Control of Light Propagation in Disordered Media.”“When people try to look into an opaque medium, especially biological material, they use the ballistic light, the light that has not been mixed up by the medium due to scattering. But as you go into the medium, the ballistic light becomes less intense, limited by the scattering process.”Instead of being limited by scattering, though, the group at ESPCI instead looked for ways to use scattering to their advantage. Gigan and his colleagues passed light through zinc oxide, which is common in paint. They observed the way the light of a laser scattered as it passed through, and then created a numerical model to describe the result. “This transmission matrix is a map through the medium,” Gigan explains. “Once we have the transmission matrix, it is possible to analyze whatever pattern goes through.”The process provides the means to put together an image of something on the other side, allowing the researchers to “see” through the zinc oxide layer, even though it is opaque. Reversal is also possible, offering a way to tailor a beam that could pass through opaque material, and then focus. “Such a method could allow for applications in imaging of biological material, among other applications,” Gigan says. “This provides a way to transmit information or focus light in a medium that wouldn’t by any classical means allow that.”There are limitations, however. “This should not be construed to mean that we can see through walls with this technique,” Gigan points out. “Some degree of light has to be able to pass through, and a wall stops light from coming out the other side. You could use white fabric, paint, or paper, though. Even biological tissue, like a chicken breast, could work.”Gigan also admits that so far the process is rather slow. “Getting the matrix is a slow process, taking minutes. We used paint because it is so stable. If you wanted to actually go through biological media, or through liquid, it wouldn’t work with our current set-up, since the light transmission changes as the medium moves.”For now, the group at ESPCI is working on tackling the problems presented by technology. “The main limitation for using this technique in biological microscopy is technical. There are some hints of how to get the transmission matrix faster, but at the moment we’re not really ready.”Despite the limitations, Gigan sees some current applications. “There are implications for nanotechnology, and the propagation of light in this system is interesting. It offers a basis for the idea of manipulating the light wave, and we believe this could be a promising approach to imaging. Perhaps in five years we will have the technology to take this even further.”

Now a theoretical physicist from the University of Minnesota in the US has analyzed the problem mathematically and determined the best strategy. Citation: Basketball shot selection analyzed mathematically (2011, August 5) retrieved 18 August 2019 from https://phys.org/news/2011-08-basketball-shot-mathematically.html Graduate student Brian Skinner decided to analyze basketball shot selection after hearing about traffic flow research that reached the unexpected conclusion that average commuting time could be reduced by road closures that force drivers to travel by routes they would otherwise avoid in order to try to minimize their own commuting time. The traffic flow diagrams reminded Skinner, an enthusiastic fan of basketball, of diagrams of the flow of basketball players in a game. The surprising conclusion also reminded him of a basketball theory named after Patrick Ewing, a high-scoring basketball player. When the games of Ewing’s team were analyzed it was discovered that the team won more games if the big-scoring Ewing was absent.Skinner realized that most of the mathematical equations and variables used in analyzing traffic flow could also be applicable to basketball and the movement of the ball in the game. His analysis, published at arXiv.org, concentrated on the movement of the ball as it approached the hoop.Skinner’s model aimed to find out how likely the shot is to go in before the player should make the shot. Shots more likely to go in were classed as higher quality shots, and the model assumed that the quality of shot opportunities falls randomly. The mathematical model demonstrated the optimal strategy for scoring the maximum points is for the team to take their time and concentrate on making high quality shots as long as there is sufficient time remaining for the shot. The model also concluded that a team playing a faster game and having twice the shot opportunities of its rival should not have double the shooting rate, but taking more time and being more selective about which shots to take would give them the biggest advantage. So, for example, if the slower team shoots at an average rate of 20 seconds, the team playing twice as fast should not shoot every 10 seconds but should take an extra three seconds on average, giving a shooting rate of 13 seconds.

Explore further Did Climate Influence Angkor’s Collapse? Now, work by a group of scientists indicates it may have been due to drought. The group, led by Mary Beth Day, an earth scientist with the University of Cambridge, is to have the results of their efforts published in a report in the Proceedings of the National Academy of Sciences. The Khmer Empire existed from the period between the 9th and 15th centuries and was centered around the city of Angkor. During that time, it’s very clear that great effort was put into capturing massive amounts of water that came from the skies during the monsoon seasons in the summer, to support drinking and crop growing during the rest of the year. The system apparently worked great for a long time, then suddenly didn’t. The reasons put forth for this sudden change have varied, from disease or warfare, to public strife, to changing environmental conditions. Now, it appears due to this latest research, that at least one of the major factors was indeed environmental.To find out if the problem was a dearth of water due to changes in the weather or the water system, the team took soil samples from one of the largest reservoirs (called barays) built by the Angkor people. Digging down as far as six feet, the team found that prolonged drought and perhaps overuse of the soil for farming may have led to a society unable to feed itself, a sure and straight path to an untimely demise if ever there was one.In studying the soil samples, the team was able to see sediment deposits that had built up on the bottom of the baray over time. During the years leading up to 1431, thinner layers indicted less water became available for storage. They also showed that the rainfall was more erratic. Instead of steady rains during the monsoon seasons, huge storms would erupt flooding farmlands and dumping massive amounts of soil into the baray, which were then followed by periods of no rain at all. The result was much less water available for drinking and growing crops during the drier seasons, and possible destruction of crops that the people were able to grow, due to flooding.This new research doesn’t prove for a fact that it was drought that led to the demise of the Khmer Empire, of course, as there were other factors involved. War with neighbors, the conversion of many of the inhabitants to Buddhism, and natural dispersion due to increasing trade with other countries, all likely had a hand. But it does appear that changing weather patterns might have been the final straw. © 2011 PhysOrg.com (PhysOrg.com) — The Khmer Empire, known to many as the Angkor Civilization, was a society of people that lived for several centuries in Southeast Asia in what is now Cambodia, Thailand, Laos and Viet Nam. What has kept the memory of the empire alive are the huge structures built by the people who lived in the area during that time. Also of note were the roadways, canals and water movement and storage systems that were constructed to support a large population. But like many other lost cultures, what was once a flourishing metropolis, in a very short period of time, gave way to collapse.

Indonesia is the fourth most populous country in the world with its people scattered over many islands. It’s also a place with frequent earthquakes and volcanic eruptions—approximately 40 percent of the people in that country make their living from agriculture, generally near the coasts. Taken together, these factors will likely mean major disruptions for the country as global warming causes temperatures to rise, rainfall to change and sea levels to rise. In their study, the researchers sought to learn how temperature and rainfall changes impacted permanent migration in the country, from one region or island to another.The researchers used data from the Rand Corporation’s, The Indonesia Family Life Survey, which has been running since 1993/94. Among other things, the survey tracks the movement of 7,185 people living in that country. The researchers compared the migratory data from the survey with weather data from the same period to see if any patterns might emerge. They found that if the average temperature for any given place was below, 25 °C, small increases in temperature did not give rise to permanent migrations. In places where the average temperature was above 25 °C, however, temperature increases did cause permanent migration to occur. And the more temperature increased, the more people moved away. As an example, they noted that a one degree rise, from 26 to 27 degrees raised the probability of migration by 0.8 percent, but the probability jumped to 1.4 percent if the temperature rose from 27 to 28 degrees. They noted that changes in rainfall had a similar impact, but was not as pronounced.The team conducted similar studies on natural disasters in the area to see if they had a similar impact and found migration from such events tended to be short term as people generally moved back when able to do so.The researchers suggest their results indicate that Indonesia is likely to see large permanent migration as global warming causes rising temperatures, with people moving away from some of the most heavily populated provinces, such as Jakarta. They note also that such migration trends are likely to occur in other countries as well. Journal information: Proceedings of the National Academy of Sciences (Phys.org) —A team of researchers in the U.S. has found that local temperature increases only caused permanent migration in Indonesia when such increases occurred above 25 °C, providing hints of possible migration patterns as global warming continues in the future. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they used data from another study to track migration over a multi-year period as a means of predicting migration patterns due to global warming.

The study is made possible by the availability of household panel data from Indonesia with an exceptional tracking rate combined with frequent occurrence of natural disasters and significant climatic variations, thus providing a quasi-experiment to examine the influence of environment on migration. Using data on 7,185 households followed over 15 y, we analyze whole-household, province-to-province migration, which allows us to understand the effects of environmental factors on permanent moves that may differ from temporary migration. The results suggest that permanent migration is influenced by climatic variations, whereas episodic disasters tend to have much smaller or no impact on such migration. In particular, temperature has a nonlinear effect on migration such that above 25 °C, a rise in temperature is related to an increase in outmigration, potentially through its impact on economic conditions. We use these results to estimate the impact of projected temperature increases on future permanent migration. Though precipitation also has a similar nonlinear effect on migration, the effect is smaller than that of temperature, underscoring the importance of using an expanded set of climatic factors as predictors of migration. These findings on the minimal influence of natural disasters and precipitation on permanent moves supplement previous findings on the significant role of these variables in promoting temporary migration.Press release

Digital marketing has emerged as a formidable challenger to traditional mediums globally and India is at forefront of tapping the impact of this disruption. Indian companies are leveraging the potential of Digital tools and platforms to share their message across the target audience. The most common form of marketing is SEO and SMO on Google, Facebook and their allied platforms. Making a content viral has become the benchmark for success on these platforms and youtubers reviews of products or services have turned into a reference point for potential purchasers before settling on a choice. Though, various studies are indicating the trend that traditional digital platforms are facing incumbency as they deliver a non-interactive mode for audience to consume content; the contemporary generation is found to be seeking more dynamic mediums where they can also be involved in content creation and not just as a passive audience. Also Read – Add new books to your shelfLive Video Streaming Platforms such as BIGO LIVE have thus emerged as a panacea for the both content creators and consumers as they empower them via a platform that makes digital interaction interactive and engrossing. Platforms such as BIGO LIVE have spawned a fresh talent pool of influencers who showcase their talents and have been able to amass their own fanbase. This presents an excellent opportunity for brands to collaborate with these emerging artistes via the platform to create exciting campaigns with out of the box ideas that enables them to reach out to their consumers in an innovative manner. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe live video platform can be integrated within main marketing campaign and can be leveraged to stimulate interest of the masses on ground level. Some positive qualitative outcomes of these campaigns are: 1. Transparency: A live video stream allow a brand to gain trust of the audience as impromptu and unedited live videos are more realistic when compared a normal video upload on traditional platforms. A live video review of a product or service creates a sense of authenticity for the audience and allows brands to position themselves as transparent in approach and open to feedback. 2. Interaction with Brand Ambassadors – Live streaming is a perfect medium for celebrity and KOL brand ambassadors to interact with their fanbase. Live Streaming also removes resource limitations since only a smart phone and data is needed; they can come online and instantly connect with their audience at any time of day. This adaptability enables the brands to reach out directly to a global audience where they are able to ask questions relating to the product or service and receive an instant answer. This is a win-win situation for both target audience and brand with instant gratification. 3. Trust is a two way street – During live streaming, brands not only can interact with their intended interest group but can build trust among the user group.

Brands who wish to gain unfiltered reviews from their target group can utilise this channel. 4. Announcements/Launch : A top management personal can use this platform for both internal or external announcements thus sharing the new updates on real time basis. Similarly, a brand can use their designated live streamers to propagate the news about their new offerings via these platforms by choosing to share the announcement with few and creating a chain of event or video logs about the news, thus making it viral among the selective audience or masses. 5. Campaigns: Brands can create video campaigns and ask users to participate in the same in the form of talent hunt, best review, behind the scenes footage, webinars, quiz contest or anything else which may suffice the brands objective. The hashtags associated with these campaigns can become viral when they are simultaneously shared on various other platforms thus enabling a wider reach without relying on mass media platform for its content to be consumed by many. Brands can use video streaming platforms to measure the impact of their campaigns by using whole set of social media app bouquet, thus generating the numbers that they may need to call their campaign a success. The number of impressions, shares, likes etc can be mapped to see the impact it has had on the minds of target audience.

Exposure to chronic, low dose radiation — the conditions present in deep space — causes neural and behavioral impairments in mice, according to a study. The results, published in the journal eNeuro, highlight the pressing need to develop safety measures to protect the brain from radiation during deep space missions as astronauts prepare to travel to Mars. Radiation is known to disrupt signalling among other processes in the brain, according to researchers, including those from the University of California, Irvine and Stanford University in the US. Also Read – Add new books to your shelfHowever, previous experiments used short-term, higher dose-rate exposures of radiation, which does not accurately reflect the conditions in space. To investigate how deep space travel could affect the nervous system, researcher Charles Limoli and colleagues from Colorado State University and the Eastern Virginia School of Medicine in the US exposed mice to chronic, low dose radiation for six months. In the recently heldresearch, they found that the radiation exposure impaired cellular signalling in the hippocampus and prefrontal cortex, resulting in learning and memory impairments. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers also observed increased anxiety behaviours, indicating that the radiation also impacted the amygdala, the brain’s medial temporal lobe which plays a key role in the processing of emotions. They predict that during a deep space mission approximately one in five astronauts would experience anxiety-like behaviour and one in three would experience certain levels of memory impairments. The astronauts may also struggle with decision-making, the researchers noted.
We have built astonishing pyramids all over the planet, and wonders such as Stonehenge or Angkor Wat, and even entire underground cities such as those found in Turkey. Yet, if there is another competing architect on planet Earth, that’s the planet herself. Think of the Grand Canyon, Niagara waterfalls, or Ayers Rock. However, nature never sits still. She is always rearranging her landscapes and over time, we have lost some remarkable sights from our view. Or at least, the face of these places altered so much, their glory by now has been long lost.Jump-off Joe in 1920.In the United States, we have lost the extraordinary sight of Jump-Off Joe. Early photographs from the 1890s and 1910s beautifully depict this sandstone formation that resembles the shape of a shoe.This was a very famous age-old sea stack, as high as 100 feet, and it adorned the coast of Nye Beach in Newport, OR.Jump-off Joe in 1890.In its heyday, before World War I, Jump-off Joe animated stories among both Native Americans and settlers. People come to Nye Beach just to enjoy the sight of the odd rock formation.Jump-off Joe in 1990.A local business flourished by selling postcards of the landmark. When Jump-off Joe’s arch crumbled in 1916, it was the beginning of the end. A couple of decades later, the remains of the landmark were entirely washed away by the sea.And arches just seem destined to crumble. In 2008, Utah’s Arches National Park lost the Wall Arch, its 12th biggest arch and one of the most distinguished park features.Wall Arch before its August 4/5, 2008 collapse.Wall Arch was identified in 1948. Composed of an atypical Entrada Sandstone sediment dated to the Jurassic era, Wall Arch made a compelling park view for decades. Its collapse in 2008 was sudden.Wall Arch within days after the collapse.Park officials were aware of fractures that appeared on the arch, but nobody foresaw such a hasty demise. Previously, the park coped with the loss of a similar-sized arch in 1991. Fortunately, there are 2,000 more arches left in the Utah park.Azure Window, Gozo island.More recently, Malta’s Azure Window tumbled on the morning of March 8, 2017 after a heavy storm battered the entire area.The limestone natural arch, a noted cliff-jumping location that appeared even in the Games of Thrones show, was situated on Malta’s island of Gozo. It was one of the most visited landmarks on the entire Maltese archipelago.Azure Window on the island of Gozo collapsed.Have storms at sea claimed other wonders of nature? The short answer is yes. In 2005, the violent tropical storm Delta conquered Gran Canaria’s odd formation El Dedo de Dios (God’s Finger). After the storm, when its upper part plunged in the sea, the site no longer looked so special.Dedo de Dios in September 2005. Photo by Mjk1980 CC BY-SA 3.0El Dedo de Dios stood on the north of the island, where the oldest rocks are dated to 14 million years. The extraordinary sea stack, which inspired poets and artists, would have needed at least 200,000 years to gain its unearthly form.Dedo de Dios today. Photo by Mjk1980 at CC BY-SA 3.0.And in Africa, far away on the south in Namibia, there existed one more “God’s Finger.” For about 50,000 years, the unique rock known as Mukurob stood in the Namib desert, until it broke to pieces at the end of 1988. It rose 40 feet towards the sky and weighed roughly 500 tones.Mukurob. Photo taken in 1983 by Piet Opperman CC BY 2.5Mukurob was worshiped by the local population. It was the source of countless stories narrated by the Nama people and is even meddles with politics. People supposedly used to say that Mukurob might break to pieces only once Namibia is free of foreign rule.In reality, from 1884 until 1915, Namibia was a German colony, and from 1915 until 1990, when the country was known as South West Africa, it was under South African rule.Aerial view of Mukurob after its collapse. Photo by Olga Ernst & Hp.Baumeler CC BY-SA 4.0Mukurob fell on the eve of December 7, 1988, at around the same time when South Africa agreed to relinquish control of its neighbor. Namibia went on to officially declare independence in 1990.Heavy rains poured the night that the rock crumbled, but a later study suggested another reason for its fall. Perhaps Mukurob fell because of the violent Spitak earthquake which destroyed over 20 towns and hundreds of villages.The epicenter of this earthquake was miles and continents away — in Armenia. But when it hit on that same December date that year, the quake was recorded in Namibia too.Arbre du Ténéré in 1961. The tree was destroyed in 1973 and has been replaced by a monument. Photo by Michel Mazeau CC BY-SA 2.More odd events, or this time rather a stupid human mistake? In 1973, a drunk truck driver carelessly claimed another African gem — the Ténéré tree. A member of the acacia species, this lonesome landmark tree was the only living thing in a radius of over 200 miles, in the Nigerian part of the Sahara.Before it died, the Ténéré tree was an uplifting sight for numerous travelers who followed the ancient pass in this corner of Earth’s biggest desert. It was also a last-standing reminder of the times when the Sahara was abundant with life. The tree’s roots, miraculously enough, reached as far as 120 feet underneath the surface. Mysterious Islands From Around The WorldLast but not least, stunning natural landmarks have been lost in New Zealand, and time seems to be ticking for one wonder in Australia.In the 19th century, a volcanic eruption of New Zealand’s Mount Tarawera wiped out what was once hailed the eighth wonder of the world — the Pink and White Terraces at Lake Rotomahana.White Terraces, near Rotorua, New Zealand. These were destroyed by a volcanic eruption in 1884.The hazardous eruption occurred one summer day in 1886 and battered the five-centuries-old natural wonder.The terraces were created out of silica-rich water, pouring down the hill slopes from hot boiling geysers.In the process, the water transformed the hilly landscapes into colorful pools and terraces, with glorious waterfalls and staircases that attracted visitors from all over the world. All that is now left of the Pink and White Terraces is old paintings and photographs.The Pink Terraces (1884).Meanwhile, ocean waves and winds are altering another magnificent site nearby, the 12 Apostles in Australia.A real feast for the eyes, the 12 Apostles (which are not actually 12) are located a four-hour drive away from Melbourne, along the Pacific Ocean Road.The twelve apostles before the collapse, 2003. Photo by Cookaa CC BY-SA 3.0Persistent erosion shaped part of the limestone cliffs of the Victoria mainland into the sight of the 12 Apostles. The process produced caves inside the cliffs which, over the period of millions of years, became sea stacks.Each stack reaches a height of up to 145 feet. The site is breathtaking especially during sunrise and sunset time, when the yellowish color of the sea stack appears to take on a darker hue.2010, after the collapse. Photo by Richard Mikalsen CC BY-SA 3.0Until 2005, these strange formations numbered a total of nine, but that year one of the bunch plunged in the water. Time will likely claim more stacks as it passes.Read another story from us: The push for answers to the mystery of the lost Roanoke colony of 1587Yet, the 12 Apostles might be a never-ending work in process. Erosion keeps taking its toll on the huge cliff facing the sea stacks. Perhaps hundreds, if not thousands of years from now, some entirely different humanity will look at the site which we once called the 12 Apostles and see a different constellation of sea stacks waiting again for time to pass.
The history of imperialism and empire-building has left a dark legacy on the world that many are still coming to terms with. While certain dictators and their ambitions — most notably Hitler — are well-known, other figures fade into the background. One of those figures arguably is Leopold II of Belgium, who between 1885 and 1908 created the notorious Congo Free State in Central Africa.Leopold IIAs described in a Guardian piece from 1999, “Leopold certainly emerges as an unattractive figure, described… by (Benjamin) Disraeli as having ‘such a nose as a young prince has in a fairy tale, who has been banned by a malignant fairy.’”Some regard him as a callous invader who would stop at nothing to realize his business interests. Others believe him to be a more misunderstood individual. Reckless yes, but blind to some of the atrocities carried out in his name.Leopold II at his accession to the throne.Why did Leopold take control of this area in the first place? The New Yorker wrote in 2015 that he claimed to want civilization for this faraway continent.He “wanted his country to join the league of European empires, but the Belgian state refused to finance its part in western Europe’s expensive scramble for Africa. So they outsourced the task to Leopold, who used personal diplomacy to convince the European powers to grant him control of a large portion of the Congo basin.”Blackwood’s Magazine – 1899 February’s cover.The forces of commerce and the power of money soon turned this journey into something much darker. Dense jungle was seen as a valuable source of rubber. The Congolese were forced to risk life and limb, slashing vines and exposing themselves to the raw material, which welded itself to their skin.“Leopold’s playground was an astonishing 76 times the size of Belgium,” The New Yorker observed. “The Congo Free State evolved from a vanity possession into a slave plantation.”Map of the Congo Free State in 1892.This relentless quest for profit had many agents, who would violently push the population toward their goals. The Guardian says, “many of Leopold’s officials… terrorised the local inhabitants, forcing them to work under the threat of having their hands and feet — or those of their children — cut off. Women were raped, men were executed and villages were burned in pursuit of profit for the king.”A particularly grisly detail was a trade in severed hands, which were delivered in lieu of a missed quota. The nightmare of that time and its bleak psychology was immortalized by Joseph Conrad in his 1899 novella Heart of Darkness, the basis for war movie odyssey Apocalypse Now (1979).Conrad in 1904 by George Charles Beresford.“With its grisly, bloody imagery, one might imagine that Conrad exaggerated the awfulness of the regime,” the New Yorker wrote. “In fact the cold details of missionary journals make even more horrifying reading.”Eventually the wider world became aware of what was going on in the Congo Free State. The outcry led to it being taken out of Leopold’s control in the early 20th century.Congo Free State, 1899.The bloodshed didn’t quite end there. History Today noted in 2012 that “Even after the Congo Free State was abolished and an official Belgian colony was established, in 1906, the atrocities continued, including the death of more than seven thousand forced laborers who were pressed into expanding a railroad in the nineteen-twenties.”It was a real life horror on an epic scale, with millions said to have perished. However some historians and other commentators have stopped short of calling Leopold’s ruthless reign a “holocaust.”Cecil Rhodes attempted to expand British territory northward into the Congo basin, presenting a problem for Leopold II.The Guardian quotes Barbara Emerson, who wrote a book on Leopold. She argues “Leopold did not start genocide. He was greedy for money and chose not to interest himself when things got out of control. Part of Belgian society is still very defensive. People with Congo connections say we were not so awful as that, we reformed the Congo and had a decent administration there.”Related Video: Argentina Federal Police Seize Massive Collection of Nazi And Illegal Historical ArtifactsNevertheless, the things carried out on his watch stained his reputation forever. The New Yorker states, “Estimates for the number of people killed range between two and 15 million, easily putting Leopold in the top ten of history’s mass murderers. When he died in 1909 the king’s funeral cortege was booed.”Comparisons are inevitably drawn between what happened then and more famous outrages. Leopold’s time connects “the imperialism of the 19th century and the totalitarianism of the 20th… the sheer scale of the terror, the role of bureaucracy and the near-genocidal numbers of dead draw comparisons with Hitler’s Lebensraum and Stalin’s war on the Kulaks.”Whether Leopold can be viewed as a dictator or a cold-hearted businessman, the chaos he instigated has echoed through the ages. The truth behind his rule is certainly uncomfortable for some, yet the industrial levels of human misery cannot help but be acknowledged.History Today sounded a note of caution when summing up the role of Leopold in the Congo. While evil was present in the jungles of his Free State, the conquest and exploitation was by no means unique to Belgium.Read another story from us: The Madness of King George and the Unsightly Blue Stuff it Produced“While it’s clear that much of the Belgian public is still ambivalent about the country’s history in Africa,” it says, “it should be noted that the citizens of many other former colonial powers also have complicated relationships with their own histories.”The scars of so-called civilization are visible hundreds of years on, and will likely never fade.
