Stopping Nemani Nadolo like trying to stop a slow-moving car, says university lecturer

first_imgCrusaders wing Nadolo blew through AMI Stadium like a tornado as he charged 33m down field against the Blues last weekend, beating flanker Blake Gibson and then clamping fullback Duffie in the glare of his headlights. For Duffie, listed at 92kg, it may have been one of those moments where he wished an escalator to the heavens would suddenly appear. He knew he had to try and stop the 135kg Nadolo, but a small voice inside his mind may have also reminded him about the importance of self-preservation. Depending on which team you supported, what followed was either a moment to cherish or one to bury: Duffie, a former NRL player with the Melbourne Storm, went in high with his right shoulder and ricocheted off Nadolo with such force his feet literally left the ground, and he sailed back through the air. Nadolo was then tackled by Ihaia West, but the ball was recycled and Kieran Read scored a crucial try for the Crusaders. When asked about the incident after the match, Nadolo was almost sheepish. “As leaguies are, he is a very good defender so I knew I had to go all-in,” Nadolo said. “It was kill or be killed … It was good to win the contest there.” Jenny Clarke, a senior lecturer at the University of Canterbury’s college of education, is contemplating using the footage of the Nadolo-Duffie clash during her classes in biomechanics. It is all very well teaching students how to figure out a complicated physics equation, but it also helps if they can see it put into practice. “So we look at it from ‘real world’ stuff. Things like that clip, I will probably end up using it,” Clarke, who includes a Doctorate of Philosophy in theoretical physics at Oxford University among her qualifications, says. “It would be very handy.” This equation does a good job of explaining the force involved in such collisions, notes Clarke: F = impulse/time: that is a momentum of something like 960kg-m/s divided by say half a second would give you 1921 N = 423lb. For those of us who are unable, or unwilling, to twist their melons around this calculation, Clarke is prepared to put it in layman’s terms.When someone the size of Nadolo is speeding towards a defender, it could be like trying to stop a slow-moving car. “Normally when you are looking at forces, it depends on how fast someone is moving as well,” Clarke explained. “Because what you are trying to do is get rid of all the momentum someone has got, get rid of all the energy if you like. So that depends on how heavy the person is and how quickly you are moving.” She also used her understanding of physics to offer advice to anyone who is in the predicament of having to tackle Nadolo in full flight: Words like impulse, momentum and impact were aired. “It is a little bit like to trying to catch a cricket ball. If you just try and catch it with a flat palm that really hurts, so what you tend to do with a catch a cricket ball is move your arms down a little bit. “That is the sort of thing you might do when trying to stop Nadolo. Just wrap your arms around him, and slowly slow him down. Rather than have that shoulder charge which is a very, very high energy impact. “Just try to get your arms around his legs, really, and try and slow him down.”Caption: Crusaders wing Nemani Nadolo charging through Blues’ defence in Christchurch, NZ.last_img read more

Soccer from another era: unthinkable rules today

first_imgAs of April 23, 2020, it is practically unthinkable for any fan to watch a soccer match without video arbitration.. Needless to say, there are other rules of yesteryear, already forgotten, that would have no place in today’s king sport. The IFAB rewrites the regulations each season that governs the competitions introducing small nuances such as the offside centimeters, the presence of two soccer players in the central circle or the neutral boats. However, in their day they had to face major renovations to make football what we know today. These are some of the rules that were once written in the universal book.1- Goal without stringerIn the initial rules of soccer, the clubs did exist, separated from each other by eight yards or, what is the same, 7.32 meters. There was no bond between the two, not even a tape. What’s more, the goal had no height limit, only width. In 1863, the Football Association made that decision, which would eventually be corrected over time. Currently, there is the crossbar, located 2.44 meters above the goal line.2- There was no regulation ballTake a look back at the football season at recess. One day one played with the ball of one, another with that of another … And each one had a weight or was inflated differently. As impossible as it may seem, this also happened in professional soccer. It was in the 1930 World Cup final, when Uruguay and Argentina faced each other. By not agreeing on the ball to use, FIFA established that the first half will be played with the Argentine ball and the second with the Uruguayan. At halftime, the Albiceleste won by two goals to one; in the end, Uruguay won 4-2. A ball decided the champion of a World Cup.3- A penalty without a pointThe penalty was always launched from the 11 meters from which it is shot today. However, this distance was not always measured by the current point. Before, the distance was measured as the space of the barriers is now calculated by eye. The referee counted eleven steps of approximately one meter each starting from the center of the goal and from there the shot was executed. Obviously, the calculation was not always accurate and the distances varied depending on the match. 4- The silver goalAn option present in video games, but which was also applied in real life. In fact, it is the closest rule of all those set out along these lines. The golden goal was criticized for leaving no margin of reaction to the rival and UEFA and IFAB proposed this new method. The silver goal was based on the fact that if a team scored in the first part of extra time, they would win the game as long as they had an advantage at the break. It was applied in the Eurocopa of 2004 and had special importance. Traianos Dellas, Greek footballer, gave the final to his family by scoring the decisive goal in the 105th minute. The second half of overtime was not played.5- The field could measure up to 182 metersIt is also part of the first rules of football, created in October 1863. At that time, exact measurements for the playing fields were not defined and, in fact, the margin was quite wide. The maximum size allowed was 200 yards or 182.8 meters. Wide, a total of 91.4 meters was allowed. Now, for international matches a length of between 100 and 110 meters is required in length and 64 and 75 in width. A difference of more than 70 meters from the initial idea.6- Assignments were allowedIt was not until 1992 when the transfer regulations were first introduced. Before, it was allowed, so constant losses of time were common using the favor of being able to catch the ball with the hand. A key game for the development of this rule was the one that faced Boca Juniors and Oriente Petrolero in the Libertadores. The tie favored both and eliminated River Plate. They used the goalkeeper as a resource to pass the time and sign the tables that satisfied the two rivals.7- Draw and ‘replay’It is a formula still used in England and other competitions. In Spain it is unthinkable. At least, repeat a table game up to three times, as happened in the Copa del Rey finals of the last century, such as two of which Barcelona won against Real Sociedad: 1913 and 1928. The problems were constant: agreement to set a new date, availability of the stadiums … Now, the extension and penalties are indisputable.last_img read more

Tyler Extols Liberian Media

first_imgSpeaker J. Alex Tyler has commended the Liberia’s independent media for what he described as “the professional and splendid coverage of the December 20, 2014 Special Senatorial Election in the country.”At a reception marking the official opening of the 4th Session of the 53rd National Legislature yesterday at the Capitol Building in Monrovia, Speaker Tyler thanked the media for its “balanced, credible and on-the-spot reportage in the recently ended election nationwide.”“For the first time in my political life, I witnessed such keen and professional work done by the media. As watchdogs of our democracy, they help keep the process honest by being in every nook and cranny of the Republic during dark and difficult nights, making sure that only genuine results were communicated,” Speaker Tyler declared.The Bomi County Representative asserted, “Without smart-phones or laptops or other sophisticated gadgetry of the Western media and, without any immediate pecuniary dividends deriving to themselves, they labored in rain, in stress-and-strain and many other difficult conditions to ensure that only the truth, and nothing but the truth about the elections got out.”He pledged his unflinching support, with the assistance of his colleagues, to ensure that appropriate budgetary consideration be made to facilitate proper training for the media.According to him, the proposed training, if approved, will be conducted in collaboration with the National Elections Commission (NEC) with the intent to ensure a sustained, continued and robust reportage in the area of elections coverage.“Indeed, you are the watchdog of our democracy, the harbinger of the new Liberia and the heroes in the quest for honesty, integrity and fair play in electoral politics,” he declared.The Unity Party lawmaker praised members of the Electoral Body for conducting a peaceful and credible election across the nation, adding that their role played was vital.He then welcomed the 13 new senators-elect to the Capitol Building, noting; “Please remember your promises made to the people that were not made under threat or duress.”Speaker Tyler reminded his colleagues from the sister chamber about their duties which include, representation, supervision and crafting laws, as imperative and must be kept uppermost in their minds and actions at all times.“For those who lost or were not considered by the people this time, I say, take heart. Better days are yet to come; and I pray that you become a part of Liberia’s golden years, in public or private service, yet to come,” he asserted.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)last_img read more

PPP promises to adhere to dual citizenship law regarding MPs

first_imgPeople’s Progressive Party (PPP) General Secretary Bharrat Jagdeo has committed to ensure that the laws regarding dual citizenship for Members of Parliament (MPs) are upheld.While Jagdeo said the PPP has no intentions of returning to the National Assembly, when asked how he hopes to deal with the situation if they had to return, he said, “We will uphold the law.”At present, the PPP has three MPs who have dual citizenship. They are Opposition Chief Whip Gail Teixeira, who is a Canadian citizen; and Adrian Anamayah and Odinga Lumumba who are both US citizens.However, he said that if there was need to return for the handling of issues relating to the holding of elections, those who want to hold on to their dual citizenship would be recalled and replaced.He told the press that his Party has not yet decided on who would be the three replacements, but said that such matters could be discussed quickly and decisions could be made in no time.Jagdeo said that the executive would first have to discuss the matter and if it led to replacements, then they would have to refer to the electoral list.It is not clear if any of the PPP/C MPs plan to give up their dual citizenship, except for Teixeira who is a long-standing member of the Party and has served in high-level positions such as presidential advisor.In the meantime, the lone Alliance For Change (AFC) MP who holds dual citizenship is Business Minister Dominic Gaskin. He was born in the United Kingdom, but is a citizen of Guyana by descent.The AFC has argued that the issue of renouncing citizenship does not apply to Guyanese who were born in another country. It believes that Gaskin could remain an MP because of this.On the other hand, A Partnership for National Unity (APNU) members including Minister of State, Joseph Harmon holds American citizenship and so does Public Health Minister Volda Lawrence. Foreign Affairs Minister Carl Greenidge and Minister of Public Service, Rupert Roopnaraine are also dual citizens. They are citizens of the United Kingdom.However, none of the APNU members have indicated a willingness to give up their citizenship.The controversy concerning persons with dual citizenship in the National Assembly surfaced after former Government MP Charrandas Persaud voted in favour of a no-confidence motion, which was tabled by the Opposition and validly passed in the National Assembly.A private citizen, Compton Reid, challenged the validity of the vote cast by Persaud in the National Assembly on the basis that he breached Article 155 of the Constitution which bars MPs from having dual citizenship.This argument also formed part of the opinions presented to Speaker of the National Assembly, Dr Barton Scotland in the hopes that he would reverse the ruling – something the Speaker ultimately refused to do.According to the acting Chief Justice Roxane George, by swearing allegiance to another State, a dual citizen is not qualified to be elected to serve in the National Assembly.She noted that while Persaud should not have been a sitting parliamentarian because of his dual citizenship, at the time of his vote on the motion, he was a valid MP; hence, his vote was valid.This issue is not peculiar to Guyana, because most recently the world was made aware of a similar situation in Australia.That country was pitched into a political crisis in 2018 after a court ruled that a senator was ineligible to sit in Parliament because she had failed to renounce her British citizenship, triggering a spate of MP resignations.Some 14 parliamentarians have resigned or been ruled ineligible since mid-2017 when renewed scrutiny on a constitutional clause set politicians scrambling to prove they only had Australian citizenship.last_img read more

HARPS GRAB SHARE OF THE SPOILS IN LEAGUE OPENER AGAINST WATERFORD

first_imgFinn Harps have made a solid start to their new season with a share of the spoils in a 0-0 draw with Waterford Utd at Finn Park.In a gritty affair, no less than seven yellow cards were shown by referee Simon Rogers.New signing Ruairi Keating had the best chance of the game to snatch three points for new boss Ollie Horgan in the 60th minute. Keating looked odds-on to score from close range at the back post from a Carel Tiofack corner but shot wide.Packie Mailey also had a shot deflected over the Waterford bar.Brian Nolan and Jack Doherty also had chances for the visitors in a game which did not boast an array of chances for either side.There was a minute silence at the start of the game out of respect of the late John Campbell Jnr, son of former Harps chairman John Campbell who was tragically killed recently.   HARPS GRAB SHARE OF THE SPOILS IN LEAGUE OPENER AGAINST WATERFORD was last modified: March 7th, 2014 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:finn harpsFinn ParkWaterford Utdlast_img read more

Chinks in the Climate Science Data

first_imgConsensus can be more robust than the data it rests on. That’s true in Darwinism, and appears to be true in climate science, according to some published doubts.A guru can lie down on a bed of nails, provided all the nails are even and solid. If the guru lies down on a bed of spaghetti, something else must be holding him up, and it’s not the nails. Let the nails represent data points of solid empirical science. How solid are the data points under climate science?In an episode of Tucker Carlson Tonight on Fox News August 8, filmmaker Josh Fox, a fast-talking environmental activist, wouldn’t allow Carlson to get a word in edgewise, which is quite a feat, knowing Carlson’s ability to hold his own in a debate. The guest hammered Carlson with the question, “Do you understand what the science is telling us about climate change?” Over and over he pounded away on that question, but the question presupposes that the science is solid and incontrovertible. Let’s examine some things that appeared recently in the pro-warmist science journals and news media. Readers can decide if these uncertainties are trivial or indicate a systemic, underlying problem with the consensus.‘Dodgy’ greenhouse gas data threatens Paris accord (BBC News). “Potent, climate-warming gases are being emitted into the atmosphere but are not being recorded in official inventories, a BBC investigation has found.” That’s a startling admission from a news source heavily in favor of the warmist consensus. “Levels of some emissions from India and China are so uncertain that experts say their records are plus or minus 100%,” writes Matt McGrath, environment correspondent for the BBC. To show how serious this is, look what he reports next: “These flaws posed a bigger threat to the Paris climate agreement than US President Donald Trump’s intention to withdraw, researchers told BBC Radio 4’s Counting Carbon programme.”These flaws posed a bigger threat to the Paris climate agreement than US President Donald Trump’s intention to withdraw.Sea level is a surprisingly variable parameter (Phys.org). Sea level is zero, right? This article shows how complicated it is, even since the 1990s, to come up with a “reference model” for sea level. Remember this when the media give dire warnings about cities sinking under the ocean due to climate change:The protracted debate about a common zero level has been eclipsed by the analysis of historical changes. Satellite data from the last 20 years show that sea levels vary greatly from region to region. Consequently, the focus is once again placed on regional levels. The first reliable data do not define a long-term average but rather a new zero point for research.Decomposing leaves are a surprising source of greenhouse gases (Phys.org). Nitrous oxide (N2O) is more potent a greenhouse gas than the carbon dioxide (CO2) that everyone worries about.  A new “culprit” for emissions of nitrous oxide has been found, and it’s not man or coal plants. It’s “Tiny bits of decomposing leaves in soil.” How potent is nitrous oxide? “Nitrous oxide’s global warming potential is 300 times greater than carbon dioxide, and emissions are largely driven by agricultural practices,” the article says. While the article only addresses farming practices, it would seem that natural leaf litter in forests cannot be ignored. Even so, measures of N2O emissions are “traditionally are about 50 percent accurate, at best,” the article notes.Overlooked water loss in plants could throw off climate models (Nature News). The caption under a lovely photo of red tulips swaying in the breeze says, “In dry conditions, leaves might lose more water through their outer surfaces than scientists suspected.” As a consequence,Errors in how scientists account for water loss from leaves may be skewing estimates of how much energy plants make through photosynthesis, according to the latest research. This in turn could jeopardize models of how individual leaves function and even of the global climate. The errors are particularly pronounced when a plant’s water supply is limited — a condition of increasing interest as plant breeders and climate scientists grapple with the effects of global warming.Methane-eating microbes may reduce release of gases as Antarctic ice sheets melt (Phys.org). Worries about retreating ice sheets releasing methane may be mitigated by lowly bacteria that eat the gas, this article says. Nobody really looked at these remote locations before. “These tiny microorganisms may have a big impact on a warming world by preventing methane from seeping into the atmosphere when ice sheets melt, said Brent Christner, a University of Florida microbiologist and co-author on the study.” Like N2O, methane is a much more potent greenhouse gas than CO2, in particular 30 times as potent.Improved representation of solar variability in climate models (Phys.org). The sun’s contribution to warming needs to be weighed against man’s contribution. This article talks about improved data sets about how the solar cycle forces climate change, which is important, since it counteracts anthropogenic forcing. Solar forcing is found to have a bigger influence than thought. The scientists believe it “will not have a significant influence on the development of global average surface temperatures.” Nevertheless, “regional effects should not be negligible.”Casting light on the dark ages—Anglo-Saxon fenland is re-imagined (Phys.org). This article investigates a time long before coal plants, smokestacks and SUVs: the so-called “dark ages” from about 400 to 1000 AD, better called the ‘early Medieval’ period. Guess what; they survived global warming. “Fen dwellers made incremental adjustments to the ways in which they collectively exploited and safeguarded the fenland’s natural resources, adapting to water levels that slowly rose as a result of climate change.”Campaigning on climate science consensus may backfire, warn scholars (Phys.org). Aware that a large segment of the public still does not accept the consensus on climate change, six authors advocated a less-pushy approach. They took particular issue with the popular rhetoric that “97% of scientists agree that human-caused climate change is happening.” For one thing, there is still intense debate about how to quantify a consensus. Secondly, the 97% slogan is not accepted by all climate scientists; the numbers “have been published by a relatively small group of affiliated researchers and challenged by other social scientists,” the advisors say. Thirdly, the public can accept scientific findings without the “consensus” argument. Fourthly, the narrow 97% value obscures wider issues with conflicting policy options. Finally, the advisors think that the 97% slogan strategy is self-defeating, sounding like overreach. Even if the value is defensible, it cannot apply to all areas of climate science. “This approach also makes the implausible assumption that publics will follow the correct policy path once given the relevant scientific information, and that acceptance of scientific consensus is needed to support specific solutions.”Non-scientists tend to be intimidated by consensus. Tucker Carlson on that TV interview had to concede that he was a reporter, not a scientist. Given these uncertainties we’ve listed above, he should have asked the guest, “Do the scientists know what the science is telling us about climate change?” – and he should not have accepted the “all scientists agree” excuse. Then he could read our report and shout, “It’s fake science!”(Visited 520 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
