Titan Continues to Surprise Saturn Scientists

first_imgSince reaching Saturn in 2004, the Cassini spacecraft has now made 68 flybys of Titan, the large smog-shrouded moon.  Space.com highlighted a recent picture showing the rings appearing to bisect the moon.  What are some of the latest findings of this alien world – the only moon in the solar system with a substantial atmosphere?    Space.com reported on work by scientists at the University of Louisiana to determine whether there is lightning in Titan’s atmosphere.  Evidence was tantalizing but not certain from the Huygens probe in 2005.  “So far, the only world where lightning is 100 percent confirmed is Earth,” said Andi Petculescu, professor of physics at the University of Louisiana at Lafayette.    Now that 22 percent of Titan’s surface has been mapped in radar, scientists at the Lunar and Planetary Laboratory at the University of Tucson in Arizona are trying to get a handle on Titan’s crater count, reported PhysOrg and Space.com.  So far they have only identified 5 certain impact craters, and 44 probable candidate craters.  That is surprising for such a large world.  By end of mission (2017) scientists should have 50% of the surface mapped in radar.    Another story on Space.com reported that the interior of Titan appears to be slushy inside.  Scientists infer from gravitational tugs on the spacecraft that Titan lacks a hard core.  Inferring the nature of the interior required measuring changes in spacecraft speed on the order of five thousandths of a millimeter per second, the article said.  Assuming the interior is as they believe, they think Titan must have built up “rather slowly for a moon, in perhaps around a million years or so, back soon after the formation of the solar system.”  National Geographic also reported this story in March and printed a larger picture of the cutaway artwork of Titan’s interior.  The finding was “really quite a surprise” according to one team member because it suggests that Titan had a very different history than Ganymede, a similar-size moon of Jupiter.    Some Utah scientists found similarities to their home state in Titan’s landscape.  PhysOrg said last March that Cassini scientists found karst-like landscape in the radar images that “suggests there is a lot happening right now under the surface that we can’t see.”  Liquid methane may take the place of water flowing under the surface.  The article includes a short video flyover of some of Titan’s “canyon country” compared with similar terrain in Utah.    One of the most unusual findings announced recently is that Titan’s river channels may be studded with gems.  JPL’s Cassini page announced a rock-n-roll feature this month: Titan may act as a “gem tumbler”  Large ice boulders like the ones seen by the Huygens Probe may tumble down channels of liquid methane for hundreds of miles.  Like pebbles on earth, which get rounded by the friction of a streambed, these ice boulders may end up as sparkling spheres of ice 1 to 8 inches in diameter.  “The effect would be similar to bejeweling an area with light-catching rhinestones.”  This may be the explanation for the brightness of the land of Xanadu on Titan – a mysterious region brighter than the rest of the moon.    Each month a Cassini scientist makes a detailed presentation on some aspect of the science returns of the mission in a series called CHARM: “Cassini-Huygens Analysis and Results of the Mission.”  The April presentation by Christophe Sotin, Titan: the Moon that Would Be a Planet (PDF) included comparisons of Titan to Earth and Mars.  Sotin reiterated the problem of maintaining Titan’s atmosphere for billions of years.  Slide 9 says, “Without the greenhouse effect caused by methane, the surface temperature would be around 70 K.”  Slide 13 states that the methane irreversibly transforms into ethane.  “If there is no replenishment (from the interior or from meteorites), the methane would disappear, the greenhouse effect would vanish, the surface temperature would drop, and nitrogen would freeze,” Sotin said.  “All this would happen in less than 100 Myrs (likely 30 Myrs).”  What is the source of the methane?  Can it be replenished from the interior?  Slide 25 says that “No convincing evidence of active cryo-volcanoes has been found so far.”  It also notes, “The number of impact craters is small.  It suggests that Titan’s surface is young.”  Young could mean anything from 100 Myr to 3 billion years, he quickly stated, but even the upper estimate falls far short of the estimated time of Titan’s formation according to standard theory.  His last slide said the “Carbon cycle implies replenishment in methane,” but then said there’s no evidence for it: “Still lacking convincing evidence for cryovolcanic features.”PhysOrg subtitled its article on crater counts with this line: “Impact craters found on Titan could help scientists determine the age of this Earth-like moon and its potential for life.”  But in the body of the story, it said, “But it’s no secret that Saturn’s largest moon is a very unfriendly place for life” primarily because of its temperature, which makes liquid water impossible.  The article later quoted the opinion of Charles Wood at LPL who said, “If it were warmer, you’d definitely think life existed there.”  Even without life on Titan, “Understanding the chemical processes on Titan may help scientists understand how life began on Earth billions of years ago,” the article said, even though the evidence so far is inconclusive about the geological prospects for life.    William Bains of the Royal Astronomical Society didn’t need evidence to tell UK astronomers what he thinks of life on Titan.  It stinks.  Science Daily shared his opinions: “Hollywood would have problems with these aliens,” he said.  “Beam one onto the Starship Enterprise and it would boil and then burst into flames, and the fumes would kill everyone in range.  Even a tiny whiff of its breath would smell unbelievably horrible.  But I think it is all the more interesting for that reason.  Wouldn’t it be sad if the most alien things we found in the galaxy were just like us, but blue and with tails?” Yes, it would be sad.  Very sad.  Very sad that scientists get their science from Star Trek and Avatar instead of empirical lab work, like they should.    The life angle is a distraction.  Nobody really believes there is life on Titan.  The L-word is the sexy girl standing next to the pickup truck that draws the public eye to an otherwise ugly, smoggy thing you would not give a second look.  Titan is fascinating in its own way, from a distance, but you wouldn’t want to live there.  Titan’s environment not unlike that of pre-biotic Earth?  Who are they kidding?  It’s vastly different.  We have water here.    It’s also illogical to talk about “life emergence” from chemical constituents.  Life is more than its parts.  Why not talk about life on the sun?  After all, the sun has protons and electrons – look: the building blocks of life!  Oh yes, it’s a little hot there, but “understanding the chemical process on” the sun “may help scientists understand how life began on Earth billions of years ago.”  Pick any planet, moon, or location in the universe and you can play their silly game.    The real story they have not addressed is the age question.  Once again we have seen them admit that Titan’s atmosphere is undergoing irreversible processes.  The methane keeps the nitrogen from freezing, but it is being depleted.  It should have rained down as ethane and formed oceans on the surface, but the surface is largely dry.  Try as they might, they cannot find clear evidence of outgassing to replenish the methane – and where are they going to dispose of the ethane, which should be a half mile thick over the whole moon?  There are also few craters.  None of this says Titan is very, very young, but it sure says Titan is likely not 4.5 billion years old.  If not that old, then many questions spring up, if not a whole new paradigm.(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

SA raises stake in natural gas

first_img21 July 2004South Africa moved another step closer to diversifying its energy sources recently when Sasol opened an 865 kilometre natural gas pipeline from Mozambique. At the same time it seems likely that natural gas – rather than coal – will be the energy source for a new multi-billion rand power station.The gas pipeline from Mozambique to the Mpumalanga plant of synthetic fuels producer Sasol, raises the country’s use of natural gas as a primary energy source from 1.5% to 4.3% of total demand.The gas, to be imported from the Pande and Temane gas fields in Mozambique through the pipeline, will be used by Sasol to substitute some of the coal used at its two plants – at Sasolburg in the Free State and Secunda in Mpumalanga – to make chemicals and diesel and to supply industrial customers in Gauteng.The pipeline immediately raises SA’s use of natural gas as a primary energy supply source from 1.5% to 4.3% of total demand, with the existing supply coming through a state-owned natural gas-to-fuel refinery in Mossel Bay.At the same time, the department of minerals and enegy will later this year invite private companies to tender for the construction and operation of a new power station that is geared to supplement the power supply for electricity parastatal Eskom.Although the government is still considering its options, it says it is “likely” that natural gas will be the plant’s primary energy source.The R14-billion project to pipe natural gas from Mozambique to Sasol’s Secunda plant was officially launched in July 2002, and is expected to be completed at the end of 2004.In 2001, state oil and gas company PetroSA completed a project to bring on stream the EM gas fields offshore of Mossel Bay, giving its Mossel Bay plant an additional eight years of gas life.South Africa’s prospects for natural gas production were also boosted in 2000 with the discovery of offshore reserves close to the Namibian border. The reserve, named the Ibhubezi Prospect, contains proven reserves of 0.27 to 0.3 trillion cubic feet of hydrocarbons.US-based companies Forest Oil Corporation and Anschutz, along with local empowerment firm Mvelaphanda, are exploring the Ibhubezi field. PetroSA bought a 30% share in the Ibhubezi project in 2003, with an eye to using Ibhubezi gas, along with gas from Namibia and Mozambique, at its Mossel Bay plant.Exploratory drilling at Ibhubezi was due to be completed in late 2004, with the consortium hoping to begin production in 2006.Sasol and PetroSA are the two major players in the synthetic fuel market. Sasol is the world’s largest manufacturer of oil from coal, gasifying the coal and then converting it into a range of liquid fuels and petrochemical feed stocks. PetroSA converts natural gas into a variety of liquid fuels like petrol, distillates, kerosene and petroleum gas.Speaking at the switching-on ceremony in Secunda, Mpumalanga Premier Ndaweni Mahlangu said the project would benefit communities from the Pande and Temane gas fields in Mozambique, as well as those who live along the valleys and hills through which the pipeline runs.It is envisaged that communities who live along the pipeline will benefit from the project through the development of infrastructure such as schools, creches and hospitals.Mahlangu said the project would also benefit those who wanted to switch over to clean illumination and cooking, whether they were in Mpumalanga, Mozambique or Gauteng.“We are committed to creating an enabling environment which not only encourages business to do what is their core function, but also offer opportunities for the small businessperson to crawl, walk, run through this corporate environment”, he said.SouthAfrica.info reporterlast_img read more

South Africans will vote for change

first_imgSouth African communities look forward tovoting in a new local government toattend to their grievances.(Image: IEC)MEDIA CONTACTS• Kate BapelaIEC+27 12 622 5579 or +27 82 600 6386RELATED ARTICLES• SA kicks off 2011 election drive• SA youngsters queue for change• South Africans go to the polls• Millions vote in record SA electionNosimilo RamelaAs the local elections draw near, an increasing number of South African communities are coming forward with their grievances, which they want municipalities to address when they begin the new term.Residents of Mamelodi township in Pretoria echoed many South Africans’ concerns on Sunday 17 April 2011 when they protested over the slow pace of delivery of essential services in their area.“We have very poor drainage systems here, which causes flooding during heavy rains,” said Ntabiseng Motolo, a resident of Mamelodi.Motolo said they are also unhappy about the state of their roads. “The roads are badly damaged with huge potholes, which spoil cars. Some areas still don’t have tar roads, making it difficult for taxis to come and pick us up here. When we vote this time, we are voting for change. We want to have such things fixed as soon as the new local leadership takes office.”Councillors from ward five in Mamelodi, where the protests took place, have since met with the community and asked that they put all their grievances in writing so they could address them. “We have heard the concerns they have raised during the protest and are already working towards ensuring that work begins on the roads and drainage system,” said Richard Mokoena.“We also want to know other grievances the community might have as we do not want to overlook anything and wait until the community feels angry and takes to the street.”Mokoena said as part of their future strategy, they would have regular meetings with the community to give them progress reports on all matters raised. He said they would commit to give community members a platform to raise their concerns and needs.“We want to ensure people know what we are doing as the council and we want to have closer interaction with the community so we can work together in resolving the problems of this area.”Making the votes countSouth Africans go to the polls on 18 May 2011 to elect their new local government representatives. There are hopes that these officials will prioritise proper housing for the many still living in informal settlements, boost access to water and electricity, eradicate corruption within local government and help fight crime and unemployment.“Gone are the days when our local council members could just promise us all sorts of great things to get our votes and then do nothing once they had them. Now they will have to earn our votes by listening to our grievances and delivering promptly on the agreed promises,” said Steven Mazibuko from Wesselton township near Ermelo, Mpumalanga province.In February, the residents there protested against a lack of job creation and access to basic services. “Our vote is the most powerful tool we have to fight for change, we want to ensure that change does take place after the municipal elections,” said Xolile Mafukade from Wesselton.Mafukade said they were concerned about corruption in their local government and wanted their voices heard before the elections. “We want the corruption to stop. We want to ensure that when we vote, we get the candidates we voted for and they deliver on what we’ve been fighting for.”The community forwarded a written memorandum to the municipality with a list of their complaints. This drew in the ruling African National Congress (ANC), which sent in a high-powered delegation to visit the area and facilitate a dialogue with local councillors and community members to find amicable solutions to the disputes.The delegation comprised Minister of Cooperative Governance and Traditional Affairs Sicelo Shiceka, Public Protector Advocate Thulisile Madonsela, Mpumalanga MEC for Cooperative Governance and Traditional Affairs Norman Mokoena and the province’s MEC for Community Safety, Security and Liaison Sibongile Manana.“This is a government chosen by the people and it has an open-door policy. At all times it is willing to engage in dialogue with our people to ensure that we solve all problems,” said Shiceka.After the meetings, the delegates reported back to the residents. They conceded that even though significant progress had been made in dealing with the community’s issues, there were still some challenges facing the local municipality.It was agreed that there is a need to set up a task team to look at what additional challenges face the community and to continuously monitor the progress made in dealing with the issues.The people come firstIn March the residents of the Meqheleng township in Ficksburg, Free State province, marched to the municipal offices there to hand over a memorandum of demands regarding service delivery. Among the issues raised, residents voiced their dissatisfaction over inadequate water supply, sewerage drain repair and waste removal. The disgruntled community set deadlines for the municipality to redeem itself, but this was not done on time. On 13 April locals held another protest demanding answers.“We will no longer be ignored by our government, we live in a democratic state where we are allowed to raise our grievances,” said John Mazibuko. “According to our constitution, water and shelter are basic needs that should be available to us all. When we go to vote next month, we want the government to know exactly what we are voting for, we are voting for change and service delivery.”Nduduzo Nyawuza from Ntuzuma in KwaZulu-Natal said local governments are currently in the spotlight and under a lot of pressure to deliver. “Since the end of apartheid in 1994 the government has done a lot to improve the lives of many communities. However, there are still those who have not seen the promises of a better life come to them and they get impatient when they see others benefiting.”Nyawuza said he believes it is good for democracy that more communities are raising their concerns. “People clearly understand their local politics more and know not to sit and accept bad or no service. They are using their voices to demand change, and their votes to appoint members they trust to bring in that change. Our government needs to listen to the people who put them in power, they need to be accountable, and they need to deliver on their promises.”The ANC has said it’s concerned about the number of protests that have taken place around the country and wants to ensure that all issues are addressed. “We are very concerned with the issues raised around service delivery and we commit ourselves to leave no stone unturned to address such grievances,” said party spokesperson Jackson Mthembu.He added they would schedule meetings with executive mayors and mayors accompanied by their municipal managers to discuss the state of local government and service delivery improvement in the local government sphere.“We want them to know that the people come first in everything we do, and we want excellence.”last_img read more

Get Schooled by These Timeless Film History Docs

first_imgMr. X: A Vision of Leos Carax (Tessa Louise-Salomé, 2014)Visually haunting and full of context, this documentary on the elusive French Director Leos Carax (Mauvais Sang, Holy Motors) is worth your time just to hear an awed Denis Lavant speak at length about what it was like to embody Carax’s visions of torment.Lavant played the lead in all but one of Carax’s films, acting as a surrogate for the director and his experience of the world. Carax’s disdain for interviews makes this film a rare document. The director speaks in voiceover or behind sunglasses, most notably about his penchant for Godzilla and how he constantly feels like an impostor. Other filmmakers and critics connect Carax’s particular sensibilities to silent comedy, the French New Wave, and even the origins of the moving image.The most important thing about Mr. X — it doesn’t impede upon Carax’s air of mystery or insistence on privacy. The style of the film sustains his mystique. Interview subjects sit in the shadows as fractured projections of light and images dance on their skin, keeping the tone even between excerpts. Flowers of Taipei: Taiwan New Cinema (Chinlin Hsieh, 2014)The island of Taiwan remained under martial law from 1949 to 1987. At the time, it was the longest-lasting regime of martial law anywhere in the world. It left Taiwan in a state of diplomatic isolation that finally gave way to an organized push for democracy in the late 1970s.Young filmmakers in the 1980s took the baton from writers in the renewed Nativist Literature movement and fed Taiwan’s cultural identity with films about people, their values, and their perspectives. Flowers of Taipei shows how these films and their politics influenced global cinema.The work of Edward Yang (Taipei Story, That Day on the Beach) and Hsiao-Hsien Hou (“The Coming of Age” trilogy, A City of Sadness) from 1980 to present is passionately discussed by film historians, programmers, and critics from Venice to Japan. Excerpts from films — like Hou’s Millenium Mambo — with all its restlessness and longing, will draw you into the poetry of Taiwanese cinema if you haven’t yet entered its gentle spaces.Flowers of Taipei compares the modes and motives of Taiwanese New Wave directors to those of filmmakers around the world. It’s a rich study of how different cultures have experienced freedom and preserved history through narrative film.See the full version here. Cameraperson (Kirsten Johnson, 2016)When you crave something more philosophical than informational, Cameraperson is a wonderful expression of questions asked by filmmakers since the dawn of the medium.Johnson meant to share her personal history as a documentary cinematographer (Fahrenheit 9/11, Citizenfour, Derrida) with this essay film. Her work resonates in candid moments from all over the world. Many of them were recorded before or after formal interviews for different projects and rescued from the killing floor. Viewers can imagine the impact of documentary-making over the last twenty-five years on the subjects being filmed. They speak freely to the camera as they navigate the complications of Johnson’s presence.That camera is both a ticket inside and a clumsy buffer between her and the space — a hospital, a locker room,  the middle of a crosswalk on a busy street in New York City. “Nothing wrong with being close, keeps everybody warm,” one subject says when Johnson apologizes for being in the way.The role of the documentary in the world is potent in Cameraperson. It’s more than a portrait of a cinematographer. It just might be a portrait of every cinematographer. Challenge your perspective with these documentaries on filmmakers, their tools, the histories they encapsulate, and the cultural context of their work.From France to Taipei, film evolves and alters the cultural landscape around it. Some films and filmmakers leave an even deeper influence behind. Look behind the scenes with five documentaries that explore what goes into becoming a legendary filmmaker.Tokyo-Ga (Wim Wenders, 1985)Beloved explorer Wim Wenders (Paris, Texas, Alice in the Cities) was mystified by the work of late Director Yasujiro Ozu (Late Spring, Tokyo Story). So, the German director went searching through the streets of Toyko for evidence of Ozu’s legacy in this hybrid travel diary and filmmaker portrait.This is not a passive or nostalgic reflection by Wenders. He found cinematographer Yuharu Atsuta, who collaborated with Ozu for more than twenty years, and requested a demonstration of their fixed-camera filming process, complete with the same model of heavy Mitchell camera the pair used on their final shoots. Actor Chishu Ryu sits embarrassed as Wenders gushes about his respect for the longtime Ozu lead. (He once watched two Ozu films featuring Ryu on the same day, Wenders says, and never before had he felt such respect for the actor.)The methodical nature of Ozu’s process, on all fronts, comes through clearly, thanks to Wenders’s narration. Here, fans of Wenders can catch a glimpse of him as a studious fan, which will delight those who love his films for their Ozu-inspired economy.center_img Cover image via Flowers of Taipei.Looking for more film history and documentary inspiration?

Directors and editors behind iconic films take the focus off scripts and sets to mine the cutting room instead — a place full of drama and high stakes.There’s no shortage of frank speech and admitted secrets in this documentary, which is ideal watch-party material for opinionated movie lovers. Actors who strong-armed their way into cutting rooms are named and sometimes maligned. Quentin Tarantino explains why he specifically sought out a female editor for Reservoir Dogs, his first film (he wanted someone to “nurture” him through the process rather than compete with his ideas, he says.) That editor, Sally Menke, then speaks about her decisions.The history of editing technology and its influence on film grammar finds a place here, too. Joe Hutshing, who edited JFK, reveals how the striking scene in which Lee Harvey Oswald walks into the Texas Theatre came about. Director Oliver Stone kept pushing for more chaos in the edit. Hutshing was using a three-quarter-inch linear editing system. He finally just started banging on keys with abandon to produce what we see in JFK.Unsung editors like Dede Allen (Bonnie and Clyde) and Carol Littleton (E.T.) break down trends and accepted norms of editing across different eras. The Cutting Edge is as fun to watch as it’s a justice done to editors everywhere and their marriage-like relationships with directors.last_img read more

Australian Women’s team to train at RAAF Base Amberley

first_imgThe Australian Women’s Open team’s final weekend training camp before the 2015 World Cup will look a little different to usual. The team will travel to the Royal Australian Air Force Base Amberley, Brisbane this Saturday to take part in a day of training. The day will include a range of activities, including a photo shoot with a Super Hornet, over-pool obstacle course, meet and greet with a range of Air Force female personnel and a ‘social’ game against the Amberley team. After that it will be back on the field for a final training session in the lead up to the 2015 World Cup, which will be played from Wednesday, 29 April until Sunday, 3 May at C.ex Coffs International Stadium, Coffs Harbour. Australian Women’s Open coach, Peter Bell said that the opportunity to participate in a day like this in the lead up to the World Cup was too good to miss. “The coaching staff had been looking for a variation to their usual/normal hard training sessions and in the lead up to the World Cup an opportunity to visit the RAAF Base came up,” Bell said. “We thought it would be good doing the ropes course out there as well as some interaction with personnel that actually represent their country in a more serious and important role – namely the security of our country. “We thought it would make for a good bonding opportunity too, given it was our last hit out before the World Cup. Most of the girls are so young I saw it as an educational opportunity as most of them wouldn’t know what a Super Hornet is let alone the enormity of the 60-plus different jobs that Air Force women do.”Group Captain Michael Gray said “it is a great opportunity for the RAAF to host Australia’s best players and have them interact with Air Force personnel. The Australian players are clearly dedicated, motivated and have great levels of fitness. Those traits are common with our Air Force people, many of who play Touch at various representative levels around Australia. “We are proud of the work-life balance that we offer our people. Sport, fitness and teamwork is an integral part of Air Force life and essential in all our challenging but rewarding positons.“We are really looking forward to hosting the team at our great facilities at Amberley and hopefully help them win the World Cup for Australia. Who knows we may even sign some up for a career in the Air Force afterwards!”  For more information about jobs in the Air Force, please click on the following link – http://www.defencejobs.gov.au/airforce/jobsDirectory/Stay tuned to the TFA website and social media channels for stories and photos over the weekend:Website – www.touchfootball.com.auFacebook – www.facebook.com/touchfootballaustraliaTwitter – www.twitter.com/touchfootyausInstagram – www.instagram.com/touchfootballaustralia Related LinksTouch World Cuplast_img read more

Jordan Spieths Grand Slam Chances

By capturing his second major of the 2015 season, U.S. Open winner Jordan Spieth has placed himself in some very elite company. It’s only the fourth time since 19581Roughly speaking, 1958 marks the beginning of the modern era of major championships; that’s when the PGA Championship adopted a stroke-play format. that the same player has won both of the year’s first two majors, and just the 13th time any player won back-to-back major titles.The conversation has quickly turned to Spieth’s Grand Slam chances. This has been the Year of Spieth on the PGA Tour, and a Slam would solidify his season as one of the best in golf history. And yet he’s not considered to be the best golfer on tour. Spieth is still the second-ranked player in the world behind Rory McIlroy, who is probably the better golfer on a per-round basis and has, in the past, won the two major tournaments remaining on the 2015 schedule.That’s why the betting markets consider McIlroy, and not Spieth, the favorite to win each of the season’s final two majors. After adjusting for the house edge built into betting odds, the sportsbook Bovada.lv assigns2To the best of our knowledge, Bovada only lists the players upon whom they’ve gotten action, and will release odds for other players upon request. The inclusion of additional players could slightly alter the house-edge adjustment we made, but those players’ odds of winning are so low that the change would be minimal at best. McIlroy a 13 percent probability of winning the British Open and an 11 percent chance of winning the PGA Championship; the site gives Spieth a 9 percent shot at winning each tournament.Those numbers are similar to the ones you’d see if you looked at how past back-to-back major winners did in their next two major tournaments. Of those who won back-to-back majors, only Tiger Woods — who won his “Tiger Slam” by capturing the 2000 U.S. and British Opens and the PGA Championship, plus the 2001 Masters — went on to win any of the next two majors, giving the group an 8.3 percent success rate per major.Of course, sometimes you can play well enough to win but run into another great performance. That’s when a method such as Bill Barnwell’s Z-scores is useful, because it tells us how well a player scored relative to the rest of the field on the same day. We can then use that number to track how often a player’s performance would be good enough to win a typical major against typical competition, which helps even out comparisons between fields of varying quality. And according to this calculation, the average back-to-back major champ’s Z-scores over his next two majors were good enough to win a generic major3From 1958 on. 11.3 percent of the time.No matter how you cut it, the odds of Spieth finishing off the Grand Slam are still fairly low — about 1 percent, if the probabilities above are any kind of guide.Even if Spieth doesn’t win the Slam, however, his future looks exceptionally bright. Back in April, we developed a model (based on the historical performance, by age, of people who won majors) to track Woods’s progress in his pursuit of Jack Nicklaus’s all-time majors record. If we plug in Spieth’s expected major count at year’s end — roughly 2.2, using the odds from Bovada — he’s currently on pace to finish his career with just under 12 major titles, a total that would rank third all-time if it came to fruition.
