first_imgLimacol KO Football Tournament…All roads lead to the Ministry of Education Ground on Carifesta Avenue this evening, where the final encounter in the Limacol Knockout Football tournament 2018 season will be played between Police FC and Pouderoyen FC, who have battled relentlessly through the competition to arrive at this place in the highly anticipated final.The competition started with a total of twelve teams, namely: Guyana Police Force, Pele Football Club, Northern Rangers, Mahaica Determinators, Campton, Georgetown Football Club, Riddim Squad, Buxton Stars, Santos, Pouderoyen, Grove Hi Tec and Beacons Football Club.They were divided into three groups, and a no-holds-barred competition followed as each team tried their best to lay claim to the first prize of $600,000 and concomitant bragging rights.Despite missing out on ending at the top of their group, Police played well during the tenser quarterfinal and semifinal matches to book their place. Their last encounter, which was with the agile Riddim Squad, saw them playing a great defensive game, separating Riddim Squad from the goal throughout the game. The Police players even went above and beyond the call of duty, acting as goalkeepers on many instances when Riddim Squad were within inches of scoring.Nevertheless, the lawmen posse’s scoring seemed to be off-target in the last game. Known as a team to capitalise on the second half, Police were able only to connect one goal for their win.Hailing from the West side, which some consider the best side, the Pouderoyen boys have fought their way out of a tough group (Santos, Grove Hi Tec and Beacons) to make it into the quarterfinal. In the semis, they met with the resilient and experienced Santos side, who held an advantage over them, having demolished them in their group encounter. Pouderoyen showed their worth by keeping Santos at bay and longing for a goal even after the 90 minutes had expired.This evening’s clash of the two top teams is sure to become a seismic event. Both teams possess great knowledge of ‘knock ball,’ a tactic that has proven to be helpful in the tournament. Police will rely on their excellent striking, as will Pouderoyen. Having made it to the final last year (against Western Tigers) and missing out, Police would want to arrest any negative change in their fortunes this time around.On the other hand, the youthful West side team are hungry for their first win. With both teams determined to take home the $600,000 cash prize, this final will be one for the books. The action kicks off at 21:00hrs.Earlier on, at 19:00hrs, the third place play-off will take place between Santos and Riddim Squad. Those teams will battle for the third prize of $150,000. Second and fourth place will receive $300,000 and $100,000 respectively.The tournament is sponsored by the New GPC under their Limacol brand.last_img read more

first_imgAnybody who thinks the hard sciences give us confidence in the real world should read this.Quantum physics was already weird, but not this weird. Nature says it has reached “a whole new level of weirdness.” The leading theory of reality contradicts itself. This is not good. For a field boasting itself as “hard science,” it’s like claiming a firm grasp on reality, opening one’s hand, and seeing nothing there.Physicists in the Cat BoxThe problem, according to writer Davide Castelvecchi, begins with Erwin Schrödinger’s famous theoretical cat.In the world’s most famous thought experiment, physicist Erwin Schrödinger described how a cat in a box could be in an uncertain predicament. The peculiar rules of quantum theory meant that it could be both dead and alive, until the box was opened and the cat’s state measured. Now, two physicists have devised a modern version of the paradox by replacing the cat with a physicist doing experiments — with shocking implications.Quantum theory has a long history of thought experiments, and in most cases these are used to point to weaknesses in various interpretations of quantum mechanics. But the latest version, which involves multiple players, is unusual: it shows that if the standard interpretation of quantum mechanics is correct, then different experimenters can reach opposite conclusions about what the physicist in the box has measured. This means that quantum theory contradicts itself.A theory that contradicts itself cannot logically be true. This is not the same problem as complementarity, such as claiming that light is both a wave and a particle. It is not the same problem as uncertainty, such as claiming that we cannot simultaneously know a particle’s position and momentum. Contradiction is a far deeper problem: it means what you believe cannot be true. Has the most widely accepted interpretation of quantum physics—the Copenhagen Interpretation—reached this hopeless state?The Copenhagen interpretation left open the question of why different rules should apply to the quantum world of the atom and the classical world of laboratory measurements (and of everyday experience). But it was also reassuring: although quantum objects live in uncertain states, experimental observation happens in the classical realm and gives unambiguous results.Now, Frauchiger and Renner are shaking physicists out of this comforting position. Their theoretical reasoning says that the basic Copenhagen picture — as well as other interpretations that share some of its basic assumptions — is not internally consistent.The “shocking implications” come from more creative versions of Schrödinger’s cat involving multiple physicists inside the box flipping coins, and multiple observers. Using the Copenhagen interpretation, two observers could be able to arrive at absolute certainty about opposite results. The reactions of ‘hard science’ physicists to this development are quite revealing:Physicists are still coming to terms with the implications of the result. It has triggered heated responses from experts in the foundations of quantum theory, many of whom tend to be protective of their pet interpretation. “Some get emotional,” Renner says. And different researchers tend to draw different conclusions. “Most people claim that the experiment shows that their interpretation is the only one that is correct.”One physicist commented, “I don’t think we’ve made sense of this.”Demon in the Maxwell BoxAnother famous thought experiment is “Maxwell’s Demon.” Around 1870, James Clerk Maxwell proposed a situation that could contradict the Second Law of Thermodynamics, which most physicists feel is one of the best-attested laws in all physics. Physics students know that atoms in a gas come to thermal equilibrium if mixed; the hot atoms never spontaneously gather to one side of a room. If an imaginary person or machine (the demon) could select atoms passing through a barrier, though, it could theoretically sort all the cold atoms on one side and the hot ones on another, providing free energy to drive a heat engine – reducing entropy and thus violating the Second Law.James Clerk Maxwell (1831-1879). Click for bio.Occasionally the science literature brings up Maxwell’s Demon for discussion. This month in Nature, four physicists proposed “Sorting ultracold atoms in a three-dimensional optical lattice in a realization of Maxwell’s demon.” Penn State imagines this as a possible way to build a quantum computer. As most physicists explain, though, the Second Law is not violated in any case, because the entropy of the demon’s work and memory storage would more than compensate for the reduced entropy of the gas. That may not be the case near absolute zero, however:“Later work has shown that the demon doesn’t actually violate the second law and subsequently there have been many attempts to devise experimental systems that behave like the demon,” said Weiss. “There have been some successes at very small scales, but we’ve created a system in which we can manipulate a large number of atoms, organizing them in a way that reduces the system’s entropy, just like the demon.”….“Because the atoms are cooled to almost as low a temperature as possible, the entropy of the system is almost entirely defined by the random configuration of the atoms within the lattice,” said Weiss. “In systems where the atoms are not super-cooled, the vibration of the atoms makes up the majority of the system’s entropy. In such a system, organizing the atoms does little to change the entropy, but in our experiment, we show that organizing the atoms lowers the entropy within the system by a factor of about 2.4.”Whether this configuration actually is the “first, to our knowledge, to capture the full essence of Maxwell’s demon on a large array of particles,” remains to be seen, since the qualifier, “to our knowledge,” is an expression fraught with the lack of omniscience.Through Two Doors at OnceFor another case of physicists living with contradiction, read Melanie Frappier’s book review in Science, “Understanding the Double Slit.” She reviews the famous physics lab experiment that seemed to show photons (thought to be particles) going through two slits simultaneously, forming a diffraction pattern on a screen that would be expected from a wave train. Richard Feynman considered this the “one and only mystery” of quantum physics. A new book by Anil Ananthaswamy, Through Two Doors at Once, recounts the history of this phenomenon, first a thought experiment later confirmed in the lab. Is light a wave or a particle? “Yes,” the answer seems to be. Physicists must embrace contradictory explanations.Ananthaswamy carefully guards himself from offering any guiding principle that might help us decide which explanation is the best one. There is, he explains, no such thing as the “right” interpretation in good science. This does not mean, however, that we have to be mere instrumentalists and reject interpretations as misguiding fantasies. We have another, better option: We can decide to embrace the diversity of interpretations at our disposal because despite their respective flaws, each likely holds the key to at least one essential aspect of quantum behavior.The Reality of UnrealityTo round out this look at physicists’ firm grasp on unreality, consider that astronomers are still looking for the universe. All they see, according to their favorite theories, is just a small fraction of it. According to Phys.org, physicists at Virginia Tech are making “Large-scale simulations [that] could shed light on the ‘dark’ elements that make up most of our cosmos” – i.e., the “so-called dark matter” and “the even more mysterious ‘dark energy’ thought to be speeding up the universe’s expansion…” Together (according to theory), these unknowns make up 96% of the universe, meaning that hard science only has a grip on 4% of observable reality.Much of even visible reality remains to be explained. Live Science reported on fast radio bursts (FRBs). “Mysterious Light Flashes Discovered in Deep Space,” Mike Wall writes, “But What Created Them?” After discussing several observations of “one of the most tantalizing mysteries in astronomy,” he refreshingly admits, “we still don’t know what FRBs are.” Some are even suggesting they might be intelligent signals from extraterrestrial beings. In fact, the Breakthrough Listen Project, funded by 100 million dollars from Russian billionaire Yuri Milner (22 July 2015), is actively involved in trying to explain them. So far they cannot rule out intelligence.Hard Science Mysteries“Ten Mysteries of the Universe” listed by New Scientist look pretty major. These are scientific questions hard science has been unable to answer so far.How did it all begin?What came before the big bang?How will it all end?Is earth in a special place?What makes monster stars?What is dark matter?Is our solar system normal?What makes supermassive black holes?Is there life out there?Why does anything exist at all?Looking over this list, one could wonder, ‘Just what parts of reality does hard science have a grasp on at all?’If the “hard sciences” cannot get a grip on reality within labs where observations are testable and repeatable, how is soft science—like political science, psychology or biological evolution—supposed to give anyone confidence in its mushier claims?Secondly, if scientists can seriously entertain intelligent causes for signals in space, from beings they cannot even describe or imagine except from their intentions, why do they refuse to use the exact same reasoning about signals in biology? The purposeful nature of the DNA code makes an even stronger design inference than unknown bursts from distant galaxies. Only worldview bias prevents hard-nosed materialists from following that evidence where it leads.(Visited 607 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgSoccer City is Soweto’s supreme pride, drawing thousands of foreign and local visitors. (Image: Local Organising Committee)Soccer City stadium rises above Johannesburg’s skyline as a symbol of rich cultural diversity and African pride – and, thanks to some innovative partnerships, it’ll remain a tourist draw card long after the last World Cup goal is scored there.Although the post-tournament viability of the R3.4-billion (US$461-million) facility – which will host both the opening and closing matches – has been questioned recently, a steady stream of tour groups since January point to its income-generating potential over the long term.There are currently seven Soccer City guides who conduct 90-minute tours focusing on the history of the stadium and the importance of its design. Some 7 000 individuals signed up for tours in March alone.“Everything about the stadium has its significance, from its shape, its colour, the seating and the architecture,” said Soccer City guide Letlohonolo Mokone.The stadium is designed to look like the African pot, or calabash, which is used to brew beer. It rests on a raised stand that represents a pit of fire. With a capacity of 94 000, the stadium is one of the largest in Africa.“The stadium is in different shades of red, which symbolise the fire,” said Mokone. “There are glass windows around the stadium, and at night when it’s lit up you can see the proper affects. It looks like something is brewing in the African pot.”The stadium is above all a symbol of Africa and the diverse cultures that will mix during the World Cup, inside the stadium, he added.The chairs are orange, the closest shade to gold, to symbolise the area’s mineral wealth and many mines. The tunnel that joins the field to the change rooms is designed to look like a mine shaft, giving the players who run through it a feel for the history of Johannesburg, which was once called “The City of Gold”.Bringing in the bucksAfter the World Cup, Soccer City will be handed over to the Johannesburg Metropolitan Municipality, which will ensure that the facility continues to function and bring in funds.The municipality has hired a task team to supervise the process. “We will be doing ongoing tours after the World Cup and are anticipating that large numbers of people will continue to show up,” said Clifford Duffey of Stadium Management South Africa.To make the stadium and the tours more sociable and marketable, Duffey said they plan to have coffee shops and merchandise stores set up where visitors can sit and relax before and after tours or games.“We are also planning on using the auditorium, which takes 200 people, to show short videos about the history of the stadium. This will include footage on the build-up to the World Cup, which will be shown to visitors as part of the tours,” he said.Duffey said the municipality will get tenant teams to use the stadium on an ongoing basis. It’s also currently in serious talks with the Premier Soccer League (PSL) to have at least 25 to 50 big games played there each year.One of the first major clashes at the stadium will be the Nedbank Cup final in May between the two top PSL teams. The league plans to sell 80 000 tickets for this game, which will be used as a test run before the World Cup kicks off in June.The name of the stadium will also be changed to National Stadium after the World Cup, Duffey said.“The stadium is an iconic structure that all South Africans can be proud of. It was not only designed for soccer, other sports – such as rugby – can be played here too.”Historical significanceSoccer City was rebuilt from the FNB stadium that was established on the outskirts of Soweto in 1987. Over the years it has witnessed some of the nation’s most poignant sporting and political triumphs, and human tragedies.In 1990 thousands of South Africans gathered there for the first public address by Nelson Mandela after his release from prison. Just years later in 1993, mourners gathered at the same place to pay their last respects to assassinated South African Communist Party leader Chris Hani.In brighter times, in 1996, the stadium hosted the African Cup of Nations, which national squad Bafana Bafana won. South Africans are hoping that the revamped site will bring the same luck to the national team 14 years on, when they face Mexico there on 11 June.last_img read more

first_imgAfter winning the gold medal in 25m air pistol event, Indian woman shooter Anisa Sayyed today thanked her husband for helping her when the chips were down.Anisa was going through a financial crisis, struggling to buy a pistol after her old gun was damaged due to a malfunction. But when all seemed lost, her husband’s company (Tulip) came to her rescue and bought her a new pistol, which is still in the possession of Customs.”My husband’s company has helped me a lot. He was there when nobody was willing to help me. But I didn’t shoot with that today,” Anisa said.Even as the women’s team of Anisa and Rahi Sarnobat basked in glory after winning gold in 25m air pistol for women, shotgun coach Marceillo Dradi seemed disappointed despite a second-place finish by Ronjan Sodhi and Asher Noria in pairs double trap event for men.Sodhi and Noria clinched the silver after they totalled 188, one point behind gold medalists Steven Walton and Steven Scott of England.”As a professional coach, I came to India with the aim to win gold, I cannot be happy with silver. I am happy for the team for winning medals but I am not happy for myself. My aim was to win gold. We have events tomorrow, so will figure our next play today evening,” Dradi said.”This was the best team we could have fielded but unfortunately we missed the gold by one point,” the coach said.Sodhi and Noria, however, were more than pleased with their efforts. “There was great competition but there was no pressure on us. I just missed the target and that happens. But full credit to England for winning the gold,” Sodhi said.advertisementNoria, the world junior champion, said “we really shot well as a team.””I am still a junior but it feels to be with the seniors, compete in such a big event and win medal,” Noria said.”Performing in front of the home crowd was a bit of a pressure but I always enjoyed shooting with Ronjan because he is my mentor,” said Noria who won the junior world championship title in August.Renu Bala Chanu cleared 197 kg to clinch the gold in the 58 kg weightlifting event for women, five kgs better than Lee Seen of Australia. Zoe Smith of England won the bronze with 188 kg.Indian boxers also continued their winning ways with Asian silver medallist Jai Bhagwan (60kg) becoming the third to enter the pre-quarterfinals with a comprehensive win over Nauru’s Colan Caleb in his opening bout.Egged on by a capacity crowd at the Talkatora Stadium, Jai dominated the proceedings to notch up an easy 11-1 triumph after getting a bye in the first round.The 25-year-old Indian, who won a gold medal at the Commonwealth Championships in March this year, now meets Tanzania’s Nasser Mafuru, who defeated Papua New Guinea’s Andrew Opugu 6-1 in his preliminary bout.Jai joins Amandeep Singh (49kg) and Manoj Kumar (64kg) in the pre-quarterfinal stage of the competitionIn tennis, Somdev Devvarman and Sania Mirza breezed into quarter-finals with easy wins but Rohan Bopanna crashed out of the men’s singles event, losing to second seed and world number 133 Australian Peter Luczak 2-6 6-7(5) in one hour and 37 minutes in the second round.Men’s top seed Somdev crushed Sri Lanka’s Amresh Jayawickreme 6-0 6-1 while Sania overpowered Cook Island’s Brittany Teei 6-0 6-2 in a women’s singles second round match.India’s chances of progressing to the semifinals of the women’s hockey event Games received a setback after the home team went down fighting 1-2 to defending champions Australia in their second Pool A match.Shelly Liddelow (11th minute) and Ashleigh Nelson (59th) scored for Australia while promising Rani Rampal (69th) pulled one back for India.Last edition runners-up India had earlier drawn 1-1 with lowly Scotland while Australia had thrashed Trinidad and Tobago 11-0.India will next face Trinidad and Tobago on Friday while Australia will be up against South Africa.In swimming, the Indian men’s 4x200m relay quartet of Rehan Poncha, Rohit Havaldar, Madar Divase and Aaron D’Souza made it to the final clocking 7 minutes 49.20 seconds to grab the eighth position in the preliminaries.Virdhawal Khade of India qualified for the semifinals of the men’s 100m freestyle after finishing 13th, while Pooja Alva also entered the semifinals of the women’s 100m butterfly by bagging the 15th spot, as the top 16 make it to the last four stage.A para-sport swimmer also brought some smiles as Sachin Verma progressed to the final of the 50m S9 freestyle men category by finishing eighth.advertisementBut the other Indians failed to advance. In women’s 800m freestyle, Richa Mishra missed the bus and also they could not make a mark in either men’s 200m backstroke or women’s 200m breaststroke.Woman shuttler Aditi Mutatkar made a successful debut, while Chetan Anand also shone as a dominant India sailed into the quarterfinals of the mixed team event with a third clean sweep over Wales.World number 17 Chetan beat Lewis Martyn 21-12 21-16 in 21 minutes to set the ball rolling, Pune girl Aditi, who made it to the squad at the eleventh hour, made it 2-0 by disposing off Turner Carissa 21-13 21-8 in 18 minutes.Top men’s doubles pair of Sanave Thomas and Rupesh Kumar then subdued a fighting Phillips James and Morgan Joe Wales pair 21-17 21-14 to give the hosts a commanding 3-0 lead.Ashwini Ponnappa and Aparna Balan then thrashed Turner Carissa and Harvey Caroline 21-11 21-13 in the women’s doubles, while mixed doubles pair of Jwala Gutta and V Diju spanked Lewis Martyn and Thomas Sarah 21-8 21-5 to wrap up a 5-0 win.Off the field, the empty seats for most disciplines over the first two days grabbed attention with the Games Federation chief Michael Fennell bluntly telling organising committee chairman Suresh Kalmadi to solve the “serious issue”.”We have discussed the issue (of poor attendance) with the OC, we have raised the question on how to get people packed at the stadium. Only the OC and Mr Kalmadi can answer all these questions … we have put this on the agenda for further discussion,” Fennell told a press conference.However, Kalmadi maintained that it was early days in the Games and with India picking up medals in many disciplines the interest of people will rise.”We sold more than 50,000 tickets yesterday. The boxing and wrestling stadiums were packed yesterday. Now public interest is high with India picking five gold. There are queues in the stadiums. It will improve everyday. That only I can say,” he said.last_img read more
