Making Saturn’s Moons with a Bang

first_imgImpacts are a favorite tool for planetary scientists to create beautiful things.The press had just gone wild with visions of a colossal impact creating the Earth-Moon system (10/18/2012), when Saturn cried, “Me, too!”  A spate of reports claims the improbable assortment of moons at the ringed planet are the result of another dramatic impact (at least in simulations).  The story was carried by Space.com, Live Science, Science Daily and Nature News (i.e., the usual suspects).It’s not that the Saturn system “did” form this way; it’s that it “could” have, as Nature News‘ headline states: “Moon-merge model could explain Saturnian system;  Simulation suggests that the moons of Saturn were once more like Jupiter’s.”  The Jupiter system is hard enough to explain, but planetologists feel it is a little more orderly than Saturn’s odd collection of small icy bodies (with active Enceladus and inactive Mimas), big icy bodies, and Titan, the oddest of all.With widely ranging densities and locations, Saturn’s six mid-size satellites are among the strangest in the outer Solar System. Measuring between 300 and 1,500 kilometres in diameter, the moons have varying characteristics: several are made almost entirely of frozen water; one, Enceladus, is rockier and geologically active; and some show evidence of submoons and rings. How did they get this way?With their charming impact video, the Saturnian modelers are apparently trying to share the limelight with the Galvanized Lunacy club: “Earth’s moon is thought to have formed from a giant impact about 4.5 billion years ago. And just as the moon and Earth are geochemical twins, the half-dozen or so medium-size moons of Saturn are similar in composition to Titan’s icy mantle, researchers said.”Science Daily included this gaffe by the modeler:“What makes the Saturn system so beautiful and unique could be its youth,” Asphaug said. “While we don’t have a preferred timeframe for this origin scenario to play out, it could have happened recently if something came along to destabilize the Saturn system, triggering the collisional mergers that formed Titan.”Nature News, though, called on Hal Levison, whose toy models have trouble creating Uranus and Neptune (8/06/2004), to do the reality check:But Hal Levison, an astronomer who studies planetary dynamics at the Southwest Research Institute in Boulder, Colorado, says that the model is currently too simple to work. As the model is now configured, he says, the mid-size moons would inevitably accrete on to Titan rather than survive in isolation.Perhaps he said this to help keep his colleagues in the planetary billiards hall employed, and to keep the game going (10/18/2012).Warning: never buy a house from these folks.  They bang the materials against each other and hope something emerges.The best part of this story is Eric Asphaug admitting that Saturn’s system looks young.  At the 15th anniversary of Cassini mission, he is well aware of the problems with the rings, Enceladus, Titan and other things that cannot fit into the standard 4.5 billion year timeline.  It’s a tacit admission that the evidence does not fit the standard story without a colossal ad hoc rescue device.

Psychotherapy Has a Shrink

first_img(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0 For better or worse, the practice of psychotherapy is shrinking, reports say.Two Brown University psychologists still believe that psychotherapy has some supporting evidence of its value, but admit that the practice is lagging.  Science Daily reported that psychotherapy is struggling with challenges coming from within and without:Psychotherapy has issues. Evidence shows that some psychosocial treatments work well for common mental health problems such as anxiety and depression and that consumers often prefer them to medication. Yet the use of psychotherapy is on a clear decline in the United States. In a set of research review papers in the November issue of the journal Clinical Psychology Review, psychologists put psychotherapy on the proverbial couch to examine why it’s foundering.The trend for years now has been to medicate the mentally ill, not to talk to them (advertising by pharmaceutical companies is a big factor).  The authors believe that psychotherapists have not made the case that some of their techniques work.  Nevertheless, even some practitioners doubt the evidence in published guidelines, preferring to work according to their personal discretion.  The field is plagued by a “proliferation of non-supported psychotherapies out there.”Research shows that many therapists put personal experience and intuition ahead of the evidence base. Gaudiano and Miller cite a 2000 survey of psychologists that found only 47 percent ever used evidence-based treatment manuals in practice and only 6 percent used them “often.” A 2009 survey of social workers found that 76 percent had employed at least one “novel unsupported therapy” in the last year.Medications, by contrast, go through clinical trials to support their “evidence-based” efficacy.  Some psychotherapists, though, dislike published guidelines; “One of the biggest fears within psychology practice is that evidence-based treatment is going to make me change what I’m doing,” the authors said.Right BrainIncidentally, the myth of the right-brained or left-brained personality has been debunked.  Science Daily reported that, while it’s true that some cognitive functions are concentrated in one hemisphere, personality types overall are not determined by left or right, researchers at the University of Utah found in functional MRI experiments.Psychotherapy is bunk that should be debunked and bonked so that it goes boink out of the science department, never again bankrolled by taxpayer dough.  This baloney that was so trendy decades ago, to the point that celebrities bragged about their shrinks and complexes with pride, isn’t a science and never was a science (9/14/11).  The fraud bequeathed by Freud and Jung and their many Darwine-drinking descendants, all contradicting one another, is better described as a sophisticated shamanship made up by a Western secularist culture trying to usurp the role of spiritual counseling.  There’s no hope in psychotherapy.  Patients are labeled with various syndromes and complexes, told they have to learn to cope if given any direction at all.  Psychiatry doesn’t do much better (5/10/13).  Patients could often talk themselves out of their problems—even talking to a computer or friend—pointing out the illegitimacy of psychotherapeutic “science.”A vibrant movement called Biblical counseling rose up in the 1980s to challenge the legitimacy of psychotherapy and of the baptized secular concoction misnamed “Christian psychology.”  Instead of treating people as “mentally ill” (excluding those who truly have a biological basis for a problem and can be referred for surgery or medicine), the movement disclaims the idea that the mind can be ill, and instead teaches personal responsibility.  Biblical counselors have had much greater success than any secular shrink by leading people to the Lord Jesus Christ, the “wonderful counselor” who heals the heart with grace, mercy, and forgiveness, granting the wandering soul a goal and a purpose for life.  “All Scripture is God-breathed,” Paul wrote, “and is profitable for doctrine, for reproof, for correction, for instruction in righteousness” (2 Timothy 3:16).  Spirit-led pastors and teachers are “competent to counsel” one another (Romans 15:14).Make sure you have the right brain not to be left behind, falling for cultural myths like left- and right-brained personalities.  You need both hemispheres, and (barring radical brain surgery or defects), you use both hemispheres all the time.  Now that you know, use the occasion when someone brings this up for a friendly reality check.last_img read more

Flying Art

first_imgQantas has unveiled a new Boeing 737-800 in Seattle featuring a striking ingenious art livery as a flying tribute to the world’s oldest continuing culture.It is the fourth aircraft in Qantas’ flying art series in partnership with Australian designers Balarinji that began with the first Indigenous livery “Wunala Dreaming” on a 747 aircraft in 1994.Balarinji’s livery design is inspired by the work of late West Australian Aboriginal painter, Paddy Bedford.The livery is an interpretation of the 2005 painting “Medicine Pocket” which captures the essence of Mendoowoorrji, Paddy Bedford’s mother country in the East Kimberly region of Western Australia.It is joint initiative between the airline, the family and estate of Paddy Bedford, Australian Indigenous design studio Balarinji and the National Gallery of Australia. The Balarinji Design Studio has collaborated on the design of all four flying art designs.Qantas chief executive Alan Joyce said “as Australia’s national carrier we will fly this livery with great pride. It not only reflects our rich history as a country, it highlights the opportunities we have to promote our indigenous culture to the Australian public and international customers.”Newly announced Qantas Ambassador Indigenous AFL player Adam Goodes took part in the delivery.“I am honoured to be standing alongside this aircraft in all its glory today It represents our people and our culture and it is only fitting that Qantas as the Spirit of Australia is using this aircraft to showcase over 60,000 years of Aboriginal art and culture.”Balarinji’s Managing Director, Ros Moriarty, lauded Qantas for its commitment to reconciliation.“In our studio’s 30th year, it is a privilege to once again work with Qantas on an iconic Indigenous art aircraft. We applaud Qantas for the leadership in supplier diversity and reconciliation.”Mendoowoorrji is the airline’s 69th 737-800.Mr Bedford died in July 2007, aged 85, and was hailed as one of Australia’s coolest painters, although only ten years into a spectacular career.He found worldwide acclaim with his innovative approach to the “Turkey Creek” style of plain ochre and sparse lines pioneered by artistic luminaries Rover Thomas and Queenie McKenzie.Mr Bedford however did not start painting for exhibition until he was well into his 70s when a Melbourne art dealer stumbled across a collection of his discarded paintings bound for the local tip at Turkey Creek.Deeply grounded in traditional lore and ceremonial practice as a senior Gija elder of Jawalyi skin, Mr Bedford enjoyed his rare ventures into the “whitefella art world” where he was feted by curators, buyers and other admirers.However in the city he cut a fine figure with his elegant silver-tipped cane, stockman’s hat and Armani suit he loved to wear to special occasions.Former Art Gallery of WA Director Alan Dodge commented to The West Australian’s Arts Editor Steve Bevis on Mr Bedford’s passing that “he was real character.”“He was also one of the greatest indigenous artists of our time and a lot of people loved him personally. He had a wonderful sense of humour and was a very warm person.Mr Bedford’s humour and warmth was to the fore despite an upbringing that would break most.After spending his childhood at Bedford Downs, Bedford was incorrectly diagnosed with leprosy just before World War II and sent to the leprosarium in Derby where he met and married Emily Watson.They had one daughter, Cathy, who was taken away, along with Theresa, a second daughter from another relationship, and raised in the mission at Beagle Bay.Returning to Bedford Downs in the 1950s, he worked for many years as a stockman for rations of flour, tea and tobacco until he was forced to leave in the mass evictions in the early 1970s after the introduction of legislated equal wages.He later worked for Main Roads shifting rocks on the Gibb River Road before a back injury forced him on to welfare and retirement at the Warmun Aboriginal community at Turkey Creek.It was there Mr Bedford took up painting.last_img read more

A manhunt has been launched for the rapists.During preliminary investigation, the girl said a youth had asked her to visit a spot to talk about the photographs he had taken of her from atop a hill. He had threatened to post the photos on social media.When she visited the spot, the youth along with his three friends whisked her away in a van. She was taken to a secluded place where she was raped and left unconscious.

Disgruntled legislators give PDP the jitters

first_imgBharatiya Janata Party (BJP) national general secretary Ram Madhav on Saturday may have attempted to put to rest the speculation on government formation in J&K, but the Peoples Democratic Party (PDP) and National Conference (NC) accused the BJP “of making bids to split local parties”.NC vice-president Omar Abdullah alleged that the State unit of the BJP had admitted to being party to efforts to break the PDP. “Power at any cost would seem to be the guiding philosophy [of the BJP],” the former Chief Minister said.Turning against partyMr. Abdullah’s remarks come days after at least five PDP legislators — Imran Ansari, Abid Ansari, Abbas Wani, Yasir Reshi and Javaid Beigh — hinted at quitting the party and expressed “disillusionment with Ms. Mufti’s leadership.” Mr. Ansari hinted at many leaders from the Congress and the NC “ready to quit their parties.” “J&K is set to witness a political tsunami,” he said.However, no MLA has put in papers. The anti-defection law in J&K is stringent.What compounds worries for PDP president Mehbooba Mufti is the growing number of disgruntled members, like Rajpora Haseeb Drabu and Lolab Abdul Haq Khan, MLAs, who are maintaining a “meaningful distance from the party’s central leadership”.Delhi meetingsMr. Drabu’s meeting in New Delhi with Peoples Conference (PC) chief Sajjad Lone, considered close to the BJP and Mr. Madhav, fuelled speculation of a third front being formulated ahead of the Assembly polls. Mr. Ansari is also considered close to Mr. Drabu and Mr. Lone, who is emerging as a point-man to cobble a third front ahead of the elections.last_img read more

‘Media targeting Rahul for a decade’

first_imgThe media has been picking on Congress president Rahul Gandhi for the last 10 years, Congress leader Sam Pitroda said on Monday. In the context of relentless questions on why Mr. Gandhi decided to contest from Wayanad along with Amethi, Mr. Pitroda said, “The media is such that they are constantly focused on this one young man for the last 10 years. Everything he does is open to criticism. If he scratches the right side, then they will question ‘Why did he not scratch the left side?’ and there will be a national debate on that.” He was speaking at the second V.K. Madhavan Kutty memorial lecture on ‘Political campaigns in the digital era’. Mr. Pitroda also panned the social media which, he said, produced fake news. “Social media amplifies lies in a big way mainly because you can hide behind fake identity,” he said.last_img read more

Antetokounmpo Leads Bucks Past Timberwolves 134-106

first_imgMINNEAPOLIS (AP) — The start to the game was unusual. Giannis Antetokounmpo’s final stat line was not.After waiting out a long delay, Antetokounmpo had 34 points and 15 rebounds as the Milwaukee Bucks beat the Minnesota Timberwolves 134-106 on Monday night.Antetokounmpo, the reigning NBA MVP, has posted a double-double in all seven games this season.“Once you go out there, you have a mindset that you’re going to play a game, you’re going to go hard,” Antetokounmpo said. “Once you cannot go hard, you’ve got to almost switch mindsets.”The game was delayed 50 minutes so one of the baskets could be fixed before tipoff. During pregame warmups, the rim the Bucks were shooting on was discovered to be crooked.“I was making shots,” Antetokounmpo joked. “So I was happy. Once they said the rim is crooked, I was like, ‘Oh yeah, that’s why I was making a lot of shots.’ Yeah, it was disturbing, because everybody was ready to go. We had to wait, like, probably, what was it, an hour?”Milwaukee Bucks’ Giannis Antetokounmpo (34), of Greece, drives as Minnesota Timberwolves’ Gorgui Dieng, right, of Senegal, watches in the first half of an NBA basketball game Monday, Nov 4, 2019, in Minneapolis. (AP Photo/Jim Mone)If the Bucks were thrown off by the delay, it didn’t show. Milwaukee shot 53.8 percent from the field.Khris Middleton added 26 points to match his season high, and Eric Bledsoe set a season best with 22. Bledsoe also had nine rebounds and six assists.“There’s just no excuses,” Middleton said. “We just had to stay professional and be as ready as we could.”Andrew Wiggins led the Timberwolves with 25 points. Minnesota played without center Karl-Anthony Towns, who served the second game of his two-game suspension for his part in an altercation with Philadelphia big man Joel Embiid last week. Robert Covington added 15 points.The Bucks outscored the Towns-less Timberwolves 62-38 in the paint.“They’re a good team,” Minnesota coach Ryan Saunders said. “You know, the credit goes to them. They overwhelmed us a little bit in the third quarter.”Milwaukee broke open the game with a 38-point third that included a 22-6 run.Antetokounmpo scored 11 points and grabbed five rebounds in the period.“We didn’t make shots. We got stagnant,” Covington said. “We didn’t come out with the urgency that we know we needed to. Just too much playing catch-up.”The Bucks were up seven at halftime thanks in part to coach Mike Budenholzer winning a coach’s challenge with 0.2 seconds left in the second quarter. That overturned an offensive foul on Antetokounmpo and resulted in a layup for him.Donte DiVincenzo scored a season-best 17 off the bench for Milwaukee.“A little bit of a strange night between the beginning and different things during the game,” Budenholzer said. “I thought the guys had a great focus. I thought the third quarter was really good.”TIP-INSBucks guards Wesley Matthews and Pat Connaughton returned to action. Connaughton (right shoulder strain) sat out Saturday’s win over Toronto, while Matthews injured his ankle Saturday and played only nine minutes.Timberwolves center Gorgui Dieng made his second consecutive start in place of the suspended Towns. Backup point guard Shabazz Napier left in the fourth quarter with a strained right hamstring. He is day-to-day.KILLING TIMEThe Bucks spent the delay in the locker room, telling stories about odd events they’d experienced in their careers or watched on TV.“The first thing that came to mind for me was back when prime Shaq was breaking backboards every other game,” Bucks center Brook Lopez said.UP NEXTBucks: At the Los Angeles Clippers on Wednesday, the second stop on a four-game road trip. Milwaukee is in the middle of playing nine of 11 away from home.Timberwolves: At the Memphis Grizzlies on Wednesday. The Grizzlies have won 27 of 37 meetings in the last decade.___By JOE ZIEMER Associated PressTweetPinShare0 Shareslast_img read more
