Artificial magnetic fields for light could illuminate correlated quantum systems

first_img In a recent study, a team of physicists, J. Otterbach, et al., from the University of Kaiserslautern in Germany and Vilnius University in Lithuania have proposed a new method for probing strongly correlated quantum systems. They show that it is possible to create artificial magnetic fields for stationary light using a uniformly rotating medium, such as a rotating optical lattice or other system. In this scenario, light behaves as a massive quantum particle in a magnetic field. The physicists predict that this system could enable scientists to study a variety of single- and many-particle quantum effects. The new design involves the use of photonic quasiparticles called stationary-light polaritons (or “heavy light”). Quasiparticles were recently suggested as a tool for investigating correlated quantum systems. In general terms, a quasiparticle can be thought of as a combination of a real particle and its surrounding environment. For instance, stationary-light polaritons are a superposition of photonic and matter excitations in the surrounding space. Unlike charged particles such as electrons, which are forced by a magnetic field into circular orbits, neutral particles such as quasiparticles do not couple with magnetic fields. “If one wants to see effects similar to electrons in solid state physics related to the presence of a magnetic field, one has to create an ‘effective’ magnetic field,” coauthor Michael Fleischhauer from the University of Kaiserslautern told PhysOrg.com. “We showed how to do this for ‘heavy light’ quasiparticles.” In the scientists’ proposed design, stationary-light polaritons are created in a rotating ensemble of atoms driven by counterpropagating lasers. The system consists of four states – two excited atomic states and two atomic ground states – which are coupled together in a closed configuration by four light fields with opposite polarizations. The scientists explain that the rotation of the light fields is similar to cold rotating gases that are used to trap cold atoms, except that the new system uses quasiparticles instead of atoms. Here, the polaritons can be described as quantum particles (either Schrodinger or two-component Dirac particles) in magnetic fields, and their effective mass can be adjusted by two control lasers. “Ideally, one wants to make the effective magnetic field as strong as possible,” Fleischhauer said. “For stationary-light quasiparticles, this [strength] can potentially be higher than what can be achieved for cold atoms.”Fleischhauer predicts that these artificial magnetic fields should be strong enough to allow researchers to study highly correlated quantum states, such as the fractional quantum Hall effect. Further, there are numerous experimental systems available today that could be used to implement this scheme.“In order to see the quantum effects one needs interactions,” he explained. “The magnetic field is, however, a necessary and important prerequisite. Its action leads (without interaction) to largely degenerate quantum states. … If interactions are switched on, the lowest energy state of the system becomes a very interesting many-body state with non-local quantum correlation. This is also the origin of the so-called fractionalized quantum Hall effect. These effects were interesting and important enough for two Nobel prizes (the integer quantum Hall effect by K. von Klitzing in 1985; and the fractional quantum Hall effect by R. Laughlin, H. Stoermer, and D. Tsui in 1998).” Cross-Dressing Rubidium May Reveal Clues for Exotic Computing Explore further (PhysOrg.com) — In general, the field of many-body physics involves the interactions and collective behavior of large numbers of particles. Scientists have made significant progress in exploring this field, which has led to applications in condensed matter physics, nuclear physics, and astrophysics. However, one challenging area that remains is understanding many-body systems on the quantum level. Two counterpropagating control lasers (blue arrows) interact with an atomic system to generate stationary-light polaritons, which behave as quantum particles in a magnetic field. The system could enable scientists to study many-body systems on the quantum level. Image credit: J. Otterbach, et al. ©2010 The American Physical Society. More information: J. Otterbach, J.

Physicists demonstrate 100fold speed increase in optical quantum memory

first_img In a new study, a team of physicists, Klaus Reim, et al., from the UK, US, and Canada has focused primarily on increasing the bandwidth of an optical quantum memory. The researchers have achieved data rates that exceed 1 GHz, which is more than 100 times greater than the speed of existing quantum memories. Although other areas still need improvement, these high-speed memories will likely form the basis of tomorrow’s photonic quantum information processors. In their experiments, the physicists use a hot cesium vapor cell as the storage medium. They overlap a signal pulse containing several thousand photons (the information) with a strong write pulse, and send both pulses together into the cesium vapor cell. The vapor induces a Raman interaction, mapping the signal pulse with the write pulse into a collective atomic excitation called a spin wave. This information can then be stored in the cesium vapor cell for 12.5 nanoseconds, after which the information is retrieved by sending a strong read pulse into the cell. The read pulse converts the spin wave into an optical signal that is measured by a detector. “There are a few steps that are required [to achieve high bandwidth], but the main approach is to use atoms with a higher energy storage state, and to apply more sophisticated control pulse methods,” coauthor Ian Walmsley of the University of Oxford told PhysOrg.com.By achieving bandwidths up to 1 GHz, the new quantum memory offers data rates that are an increase of a factor of more than 100 compared to current quantum memories, which are limited to a few megahertz. Moreover, the researchers noted that the bandwidth was limited only by the response time of the detector; theoretically, the quantum memory could be capable of even larger bandwidths. In addition, the method offers long coherence times of several microseconds. One area that still needs work is the overall efficiency, which was about 15%. The cesium vapor could store 30% of the incoming signals, half of which could later be retrieved. The researchers plan to improve the efficiency by changing the signal pulse’s attributes. The physicists also noted that this Raman-based quantum memory scheme can be broadly applied to other storage media besides hot cesium vapor, such as cold gases and solid-state systems. Also, in addition to quantum computing, quantum memories like this one will be important for quantum repeaters for long-distance communication. “Our plans are to demonstrate the operation of the memory at the quantum limit, using an external source of nonclassical light,” Walmsley said. “Challenges for the future in general are to increase the number of bits the memory can store and the readout efficiency of the memories to the point when they can be used in applications such as quantum communications links.” More information: K. F. Reim, et al. “Towards high-speed optical quantum memories.” Nature Photonics. Doi: 10.1038/NPHOTON.2010.30 (PhysOrg.com) — As with today’s computers, future quantum computers will require more than just quantum information processing; they will also require methods to store and retrieve the quantum information. For this reason, physicists have been studying different types of quantum memories, which are capable of controllably storing and releasing photons. However, these memories still face several challenges in areas including storage time, retrieval efficiency, the ability to store multiple photons, and bandwidth. Explore further In the optical quantum memory, a signal containing the information and a write pulse are sent together into a cesium vapor cell. The vapor turns the pulses into a spin wave, and the information can be retrieved by a read pulse that converts the spin wave into an optical signal. The memory can achieve data rates that exceed 1 GHz. Image copyright: K.F. Reim, et al.

Researchers build selfrepairing systemic computer

first_img(Phys.org)—Computer scientists Christos Sakellariou and Peter Bentley working together at University College in London, have built a new kind of computer that runs instruction segments randomly, rather than sequentially, resulting in a computer than in theory, should never crash. Citation: Researchers build self-repairing “systemic” computer (2013, February 15) retrieved 18 August 2019 from https://phys.org/news/2013-02-self-repairing.html One of the main reasons that computers crash is because of the way they execute instructions, i.e. sequentially. Code is written in a step-by-step fashion and the computer follows a counter that retrieves lines of code in the proper order, executing each one before moving on to the next. Problems come in when the counter becomes mixed up, or code that has been executed fails to return control so that the next line can be run. To get around that problem, the researchers in Britain have built a computer that doesn’t run sequentially at all. It runs chunks of information that is made up of both code and data, and does so in random fashion, removing the sequential processing problem. The result, they say, is a computer that is able to repair itself on the fly, and won’t theoretically ever crash.The whole idea is based on nature’s distributed error correction processing abilities as demonstrated by such brilliant constructs as the human brain. As people exist, they think, they react and respond. They do all manner of things, none of which occurs as the result of a sequential processer in a central part of the brain. Instead, things are done in a distributed manner, with different biological processors working on different things at the same time. To make this happen with a computer, the researchers built a Field Programmable Gate Array (FPGA) which is essentially a bit of electronics that serves as a sort of traffic cop. Its main job is to make sure that different segments or “systems” as the researchers call them, get called on, albeit, in random fashion, and to allocate a place for them to run. One of the benefits of such a system is that no system has to wait for another to finish before running, which means the computer can run several systems at the same time. Thus, the FPGA is a resource manager, though it also serves as the manager of information that flows between systems.Because the systems are independent of one another, there is no crash if one of them is unable to carry out its instructions. But better than, that, other systems can be introduced into the system whose purpose is to detect problems with other systems and rerun them if necessary, or to change them slightly, if need be, to allow them to complete their assigned tasks. In the computer world, that’s known as self-repairing code and it’s something many people would like to see in computers running in the real world. With this new computer, it’s been demonstrated that such a computer can be built.

Study shows evolution does not always mean more diversification

first_img The researchers were studying pharyngognathy in spiny fish—where the jaw changes over time to allow bones in the throat to grind down hard shells for digestion—to discover whether such an evolutionary adaption always works out, because the downside of it is a smaller gape, which means feasting on smaller fish. They noted that most such species live in shallow marine environments alongside other species that do not have the grinding capability. The exception was cichlids, which live in tropical freshwater places, such as lakes.Overall, the researchers found that pharyngognathy generally led to fish that evolved into niches that favored hard-shelled fish faster than did other fish, and that may have contributed to the decline of such fish species in Lake Victoria. The Nile perch, a non-pharyngognathous fish was introduced into the lake back in the 1950s and since that time cichlid numbers have been dropping dramatically. Initially it was assumed that the decline was due to the perch eating or killing the various cichlid species, but now, the researchers have shown that it was most likely due to them being out-competed—they compared the feeding performance of Nile perch against cichlids and discovered that the gape of the perch was double that of the cichlids, and that the cichlids also took much longer to digest prey. Taken together, the physical differences have clearly put the cichlids at a serious disadvantage, allowing the perch to thrive while the cichlids have been essentially starving to death. Thus, the specialization that came about due to the evolutionary adaption meant to allow them to eat a broader range of fish, in the end led to far less diversification in at least one closed ecosystem.

DOI: 10.1126/science.aab0800ABSTRACTEvolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not universally beneficial. A large-scale analysis of dietary evolution across marine fish lineages reveals that the innovation compromises access to energy-rich predator niches. We show that this competitive inferiority shaped the adaptive radiation of cichlids in Lake Tanganyika and played a pivotal and previously unrecognized role in the mass extinction of cichlid fishes in Lake Victoria after Nile perch invasion.Press release (Phys.org)—A small team of researchers with members from the U.S. and Switzerland has found an example of a fish that did not always benefit in the end from an evolutionary change.

Debunking social taboos

first_imgThe socio-historical constructions of India are often essentialized ones, framed in terms of twofold opposition and stereotypes. One of the manifestations of these stereotypes is evident in the portrayal of women and the culture of taboo associated with them.Around the world, different taboos have different sources which go beyond the individual and the household. A much larger driving force that has helped taboos prevail in India is superstition in the name of religion. Acceptance of different practices though is the nature of Indian culture. Yet, accounts of taboo question whether the project of making a ‘liberal’ nation was always fraught with religious prejudices and traditional disbeliefs. There are various taboos existing in India but one which is glaring and needs some attention is the menstrual taboo.  Also Read – Add new books to your shelfSince ages, women have been subjected to derogatory practices just because they menstruate and for such things to flourish it has to thrive at fundamental levels. Unfortunately, families and cultural groups represent these fundamental levels, where people are socialised in a certain way.  For instance, girls are taught from the very beginning that they should not let people know about it, they still have to hide sanitary napkins from male members of the family among other various reasons. This basic foundation for socialisation forces itself to look beyond the building blocks of identity. While periods can be uncomfortable for certain material reasons, a girl child is more uncomfortable because she becomes conscious of other people knowing about it. As a result, faulty socialisation facilitates blind superstition.  Also Read – Over 2 hours screen time daily will make your kids impulsiveThe experiences of female bodily processes have always been construed and placed within the narrow cultural domain in India. While menstruating, women are prohibited to enter temples, kitchen, not allowed to  have intercourse, touch pickles and the list goes on. This stark reality does not call for romanticising the issue rather it calls for normalisation. However, the kind of taboo and derogation that has been vested on the phenomenon, has led to a necessary romanticisation of menstruation.  On a brighter side, feminists like Rupi Kaur and others have helped raise awareness on this issue. Women have come out of their shells and are upfront about discussing this issue now more than ever. Also, being free about discussing periods has become a medium of seeking liberation from downtrodden cultural norms. It should be kept in mind that the enforcement of menstruation as a taboo in an extreme way makes people think of it as liberating. Had taboo not been associated with this, it would have been normalised just like any other biological process. However, normalisation of the issue remains an ideal dream, it keeps oscillating between extremes. Menstruation as a process is intrinsic to the functioning of female biology and the extent to which it has been ritualised results in the facilitation of patriarchy in our society. Menstruation is just like any other biological phenomenon, a loss of certain bodily fluids, for example, sweating or defecation or urination. So, if patriarchy could work on an issue so intrinsic, then it makes easier for us to understand how ingrained patriarchy is in our society and how women have internalised the fact since ages because women have acknowledged menstruation as a taboo – as something impure and have agreed to the restrictions placed on them while they are on their period. Hence, the sense of dirtiness that is associated is internalised at every step. Menstruation is one of the common taboos associated with women. These kind of taboos form the basis of a lot of other complex feminist issues like body shaming, where people keep talking about how they should be comfortable in their own skin and leave aside obsession of attaining a perfect figure. Both of these cases have made women overtly conscious of themselves. Ideally that should not be the case, one should be able to embrace the fact this is just a process, a routined process that is absolutely essential for a female body to function in a certain way and it’s also central to certain other processes in life like child-bearing. Thus, socialisation makes a big difference. It is probably being changed now but there are millions who are still overtly conscious about the fact that they don’t want people to know about their period. Looking for an ideal situation, where there would be no discrimination, remains a distant dream but women have to learn to get comfortable to what is naturally a part of them.last_img read more

Mercury may rise in next 72 hrs in city

first_imgKolkata: The temperature in Kolkata may go up slightly in the next 72 hours, giving respite to the city-dwellers from the cold wave condition that has been prevailing for the past few days. The Regional Meteorological Centre at Alipore on Wednesday predicted that the condition will improve in some of the South Bengal districts including Kolkata in three days. The lowest temperature in the city on Wednesday touched 12.6 degree Celsius. In the Western districts like Purulia, Bankura, Birbhum and West Midnapore, the cold wave condition may stay for a few days more. These districts can witness a marginal fall in the temperature but the overall situation is likely to improve. “In the next 2-3 days the temperature will remain a few degrees below normal. There may be a rise in the mercury in Kolkata and some adjoining districts. The cold wave condition will also improve,” a senior official at the Met office said. The cold wave condition will continue to remain unchanged in the North Bengal districts, as predicted by the Met office.last_img read more

Property worth crores gutted in Vedic Village fire none hurt

first_imgKolkata: A major fire broke out at the Vedic Village resort in Rajarhat on Monday night. A big portion of the resort was damaged due to impact of the inferno. It is said property worth crores reduced to ashes but no one was hurt in the incident.Twelve fire tenders doused the flames almost after battling for about eight hours. According to sources, Vedic Village resort authorities claimed that around 10 pm, on Monday, a lightning struck the cottages, which were made of hay. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataIn no time the fire started spreading fast because of the strong winds. At the first, the staff members of Vedic Village tried to control the fire by arranging water from their underground reservoir. But as the intensity of the fire was high, they were not able to control the inferno. Immediately, the fire brigade and the Rajarhat police station was informed. Soon, five fire tenders were pressed into action. Later, seven more fire tenders were called in as the intensity of the fire was increasing. It is alleged when the fire started media personnel, who went to cover the incident, and a few firefighters were not allowed to get into the resort. Later, the police intervened and resolved the matter. Question arises if the Vedic Village authorities had no flaw on their part, why the media and fire fighters were restricted. Also Read – Lightning kills 8, injures 16 in stateA source informed that the reception, godown and the office burnt into ashes as these structures were made of hay. Though the Vedic Village authorities claimed that the fire broke out due to lightning but the actual cause is yet not confirmed. It is suspected that fire had occurred due to a short circuit. Within an hour, the fire took a bad shape as it raged up to almost 25 feet. Guests in the cottages and the residents of various apartments within 100 metres got panic-stricken due to intensity of the fire. All the guests were evacuated and taken to a safe place. Later, fire minister Sujit Bose went to the spot and supervised the firefighting operation. According to Bose, it is not clear if any firefighting measures or license were in place at the resort. Around 3 am, on Tuesday, the fire was brought under control. Later, cooling process went on till early morning. Till Tuesday night no complaint was lodged by the Fire department. The cause of fire is yet to be ascertained.last_img read more

3 detained over unaccounted money

first_imgKolkata: Large amount of unaccounted money has been seized from Durgapur and Salt Lake on Thursday. The first incident took place at Durgapur railway station where one person was detained and Rs 70 lakh was seized from his possession. In the second case, a man was detained in Salt Lake and Rs 40 lakh was seized from him.According to sources, on Thursday, around 11 am, a person, who was later identified as Suresh Prasad Barman, was seen loitering at the Durgapur railway station by Government Railway Police (GRP) personnel. The GRP personnel kept a close watch on Barman as they felt his activities were suspicious. Later, they intercepted him and inquired what he was doing at the station. Barman said he was about to board a train to Kolkata. GRP personnel questioned what he was carrying inside his luggage bag. Barman said there were garments in the bag but the police personnel were not satisfied. Barman was taken to the police station at Durgapur railway station and there his luggage bag was opened and huge amount of money was discovered. Asansol-Durgapur Police was informed about the incident. After counting it was found that Barman was carrying Rs 70 lakh. During the interrogation, he said he had come from Varanasi and got down at Durgapur to catch a corresponding train to Kolkata.

Symbols and Meanings Hidden in Americas Victorian Architecture

first_imgWhy do some old buildings look so scary and intimidating? That’s a question which springs to mind for anyone walking past a Victorian stately home. Whether built during the reign of Queen Victoria herself (1837 – 1901) or taking inspiration from the style of the time, the passerby is confronted with the likes of Gothic gargoyles and eerie elemental symbols.Queen Victoria in 1890Are these elaborate sculptures a way of showing off, or do they have a deeper significance? The answer is both. For example, architectural experts have been taking a look at different areas of San Francisco as a sample and drawing some fascinating conclusions.This city is far from the foggy streets of Victorian England, yet much of the period’s design found its way into the buildings of areas such as Pacific Heights.Painted Ladies houses at sunrise in San Francisco, with the city skyline in the background. Colorful clouds.Writing in 2017, Architectural Digest noted that this approach endured into the 20th century. In addition to buildings erected during Victoria’s life, “many were constructed after the catastrophic 1906 earthquake and fire, which destroyed nearly 500 city blocks. In the aftermath of the tragedy, the spirit of the 19th century aesthetic prevailed.”Examining these faded white facades can bring to life ancient legends, or represent the owner’s guiding principles. Overall it creates a powerful effect that can’t help but catch people’s attention…MythologyImages relating to Greek mythology can be found at locations such as the George W. Gibbs House, designed by Willis Polk. The Victorians ushered in aspects of the modern world but still saw value in these symbols.Built in 1895, the Gibbs place was described in the 1983 book On the Edge of the World: Four Architects in San Francisco at the Turn of the Century by Richard Longstreth as “among the city’s earliest houses constructed entirely of stone and that almost no dwelling of comparable size matched the restraint of its exterior.”The Medusa’s head central to a mosaic floor in a tepidarium of the Roman era. Museum of Sousse, Tunisia Photo by Ad Meskens CC BY-SA 3.0Longstreth noted that “In a metropolis of wood, the Gibbs house became an instant symbol of grandeur and permanency.”One of its striking permanent features are the Medusa and Gorgon faces which look down on visitors from the Roman villa-style entrance. Medusa was decapitated by Perseus and her head — with its eyes and their ability to turn onlookers into stone — used as a weapon.Architectural historian Caitlin Harvey, in a 2016 article for website 7×7, commented that “Medusa or Gorgon heads were often placed on doors or gates to repel evil or enemies. It is also a strong classical reference to great ancient Greek architecture, as Medusa appeared on a number of iconic temples.”The ElementsC. A. Belden House, 2004-2010 Gough St, San Francisco, California, USA. Sanfranman59 CC BY-SA 3.0Also of interest is the C.A. Belden House, designed by Walter J. Mathews and built in 1889. For starters there’s the striking sculpture of a large Green Man face displayed prominently, reflecting a historical interest in nature.But aside from that an elemental symbol reveals a sense of optimism — a sunburst can be seen by the upper window. Harvey refers to it as “a popular motif in the late 1800s. People who lived during that time considered it a golden age… But some historians think they represent the British Empire and the notion that the sun never set on the British Empire.”Queen Anne HouseThe house is a classic example of the Queen Anne style, which is a part of the Victorian era yet at the same time in a category of its own. The 18th century aesthetic (Queen Anne ruled between 1702 – 1714) had been revived a century later.NoeHill.com wrote that it was “the flamboyant culmination of the building styles today grouped as Victorian, particularly in San Francisco where any residence built between the Gold Rush of 1849 and the 1906 Earthquake and Fire is commonly called Victorian.”Related Video: 13 Victorian Vulgarities everyone should knowAnimalsThese Victorian rowhouses are in the Haight-Ashbury neighborhood of San Francisco, California Photo by Urban CC BY-SA 3.07×7.com mentioned that “larger and more costly homes had more custom details, while most middle-class homes ordered ornamentation from a catalog or pattern book.”One popular and recurring theme was wildlife and the animal kingdom. On a domestic level, the iron sculpture of a dog is singled out. Even by today’s standards, they can be recognized as “symbols of loyalty”.A view of three elaborate victorian houses taken from Alamo Square in San Francisco.A more surprising sight could be a dolphin. Not the first creature thought of in relation to the Victorian period, but still an important one. They “symbolize swiftness, charity, diligence, and love — but she (Harvey) thinks it is popular in SF because of our coastal location”.From beasts to birds. A swallow represented “hope, rebirth, and return (swallows are migratory birds that return to their cliff-side nests year after year).” And owls symbolize ““Wisdom, intelligence, protection, and vigilance.”Purple house in San Francisco.The emphasis was naturally on capturing the spirit of Victorian times. At the same time the architecture focused the old world through the prism of what was believed to be a new and exciting era.Read another story from us: Art Deco House with Original Vintage Furnishings For Sale – Take a TourThose old and stony structures may look imposing.

1 pick Ben Simmons makes summer league debut

first_imgBen Simmons put on an NBA uniform for the first time last night in an otherwise meaningless summer league contest, and regularly flashed his limitless potential that made him the top overall pick in the NBA Draft.Admittedly, the summer league is loaded with fringe roster players and rookies, but Simmons performance has to  be encouraging for Philly hoop fans. Even though Simmons left the game in the fourth quarter with calf cramps, he finished with a casual 10 points, 8 rebounds, and 5 assists, and looked like a bully in a sandbox.Simmons looked physically dominant, and showcased LeBron like passing vision.These Ben Simmons passes tho… https://t.co/Oi0jFWIpaY— TD St Matthew-Daniel (@ProducerTD) July 5, 2016 Penny Hardaway with one of the sickest passes I’ve ever seen! pic.twitter.com/PWnG46vXGa— NBA_Mixes (@NBA_Mixes) June 29, 2016Even watching Simmons flash in his brief debut, Philly fans have to be excited for the first time in a long time.

Kevin Durant was better than LeBron James in the FinalsLeBron James is getting a hefty amount of love after averaging a triple double in Cleveland’s Finals loss. James’ supporters are citing his historic individual Finals performance as proof that he was still the best player in the Finals, even better than MVP Kevin Durant.Gottlieb thinks James supporters never miss a chance to cast his legacy in the best way possible, but in the Finals Durant was just better. Even though LeBron had an unbelievable stat line, Durant took over multiple games in the fourth quarter, including huge clutch daggers. Winning still matters and closing still matters. In these Finals, Durant deserves the nod over the King. Doug Gottlieb (@GottliebShow) in for Colin:Golden State isn’t the greatest team of all-timeGolden State’s Finals dominance has immediately spawned the debate if they are the best greatest team of all-time. Gottlieb doesn’t think so.He sees the Warriors as possibly the greatest team of the current era, but what they ultimately lack is depth that teams in the pre-free agency NBA had, and it’s not even close. He used the ’86-’87 back-to-back champion Lakers teams as an example of a team that was 10-deep with quality players.Ultimately, comparing the two NBA eras is apples and oranges. These Warriors are historic, but they aren’t the greatest team ever. It doesn’t diminish an incredible, championship season.“This is not the greatest team ever. It’s not the greatest compilation of talent ever.”last_img read more

Colin Cavs blowout loss against the Raptors has zero impact on the

first_imgThe Cavs were run off the court in a 34-point blowout against the Raptors. Things got ugly, and even featured LeBron James yelling at teammates during a timeout. It was Cleveland’s second loss by 25 or more points, and this morning some critics were already out burying LeBron’s chances in the playoffs with this roster.Colin isn’t panicked over the loss, and thinks the meltdown has zero long-term impact on the playoff picture. January struggles are nothing new to LeBron teams, and it’s typically the time where he teaches lessons to teammates and the organization. But every year, for the last seven years, James ends up in the Finals. Bet against Cleveland if you want, but Colin always bets on LeBron figuring things out. He’s been right for the last seven years.“What happened last night has zero impact on the playoffs, his relevance or his legacy.” — @ColinCowherd isn’t worried about LeBron and the Cavs pic.twitter.com/usFPppKk9A— Herd w/Colin Cowherd (@TheHerd) January 12, 2018last_img read more
