Trouble in Cosmologyland

first_imgUnderneath the veneer of certainty portrayed by TV documentaries about the universe are deep questions and controversies.  Some of these briefly appear on publicly-available news stories, only to be covered by new coats of certainty.  Are the new veneers fixing the problems or, instead, whitewashing serious weaknesses in current cosmological understanding?  Here are some quick looks under the veneer. Speaking of the Cosmological Principle, it has been wrongly been attributed to Copernicus – a man who admired God’s supreme architecture of the heavens.  Dava Sobel, who wrote the illuminating historical Galileo’s Daughter, that did much to debunk the science-vs-religion myth of the Galileo affair, has a new book out: A More Perfect Heaven: How Copernicus Revolutionized the Cosmos (Walker/Bloomsbury 2011).  Owen Gingerich reviewed it in Nature last week (Nature 477, 15 Sept 2011, pp. 276–277, doi:10.1038/477276a) and considers it “first rate… a charming and accurate book, although it omits much of the technical background in which earlier accounts revelled.”  Apparently the semi-fictional account by this gifted writer gives prominence to Rheticus, a Lutheran: “True to the historical record, Rheticus finally persuades the ageing canon to allow a copy of his manuscript to be taken to Nuremberg for printing.”  See the 4/30/2004 entry, “Lutherans Helped Copernicus,” for more non-fiction about this central character in the rise of modern cosmology; see also our online biography of Copernicus (March 2008, right sidebar) Why do most teachers, textbook writers, and TV documentary producers concentrate on the whitewash, and ignore the termites?  Find many more termites in the cosmology house by searching on “Cosmology” topics on our search bar.  Listen also to some of the things David Berlinski told National Review TV last month about scientists’ hubris about physics and cosmology (see list of episodes on Evolution News & Views).(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0 Disturbing:  “Dwarf galaxies suggest dark matter theory may be wrong,” wrote Leila Battison for the BBC News.  We’ve heard it for years; “The current theory holds that around 4% of the Universe is made up of normal matter – the stuff of stars, planets and people – and around 21% of it is dark matter.”  Why, then, did leading cosmologist Carlos Frenk call new developments “disturbing”?  The Large Hadron Collider (LHC) has been unable to find cold dark matter (CDM), an essential ingredient for the Standard Model of the birth and evolution of the universe.  “Scientists working on the problem have recently expressed dismay at the universally negative results coming from the LHC, and this has led some to consider that the standard model may be wrong.”  Either cosmologists do not understand the formation of dwarf galaxies, or (something that Frenk is “losing sleep” over), a more disturbing alternative is dawning on them: “that CDM does not exist, and the predictions of the standard model relating to it are false.” Hunt for darkness:  Various teams are still searching for dark matter anyway.  PhysOrg reported 67 anomalous results from the CRESST experiment deep under a mountain in Italy that cannot be explained except by Weakly Interacting Massive Particles (WIMPs), a theoretical form of dark matter.  That does not mean dark matter is real; only that it has not been ruled out by these unexplained detections.  Antimatter, anti-dark matter:  Meanwhile, other detectors are disconfirming dark matter.  “Antimatter enthusiasts will love it; dark matter hunters not so much,” quipped Stuart Clark for New Scientist.  “NASA’s FERMI satellite has confirmed a previous hint that there is more antimatter than expected coming from space. The bad news is that the result almost certainly rules out dark matter as the source.” Long-held assumption doubted:  We’ve been told for quite awhile that large galaxies grew by collisions with smaller ones.  “ESA’s Herschel infrared space observatory has discovered that galaxies do not need to collide with each other to drive vigorous star birth,” Science Daily reported.  “The finding overturns this long-held assumption and paints a more stately picture of how galaxies evolve.”  That is, for now.  Whatever picture emerges next, “These new observations now change our perception of the history of the Universe.” Will God Particle be science fiction?  The Higgs Boson (a.k.a. “God particle”) is running out of places to hide.  Central to cosmological theories for the origin of mass, it continues to elude detection by the Large Hadron Collider in Switzerland.  Finding the Higgs was one of the world’s largest detector’s prime missions (see video posted on Deseret News for explanation).  Believers are running out of time waiting for God-ought (where ought is slang for zero).  PhysOrg reported; “if it’s not there, it will be known to be science fiction by December.” Cosmological Principle under siege:  One of the most beloved of all cosmological notions is that the universe is homogeneous and isotropic – that at large scales, every place looks the similar to any other, so that there is no preferred direction or location in the universe.  Watch out; PhysOrg titled an entry, “New evidence for a preferred direction in spacetime challenges the cosmological principle.”  Enter an anisotropy to muck things up.  The article explains, “the universe’s expansion is accelerating at a faster rate in one direction than another. In the most recent study, scientists have analyzed data from 557 Type 1a supernovae and found, in agreement with some previous studies, that the universe’s expansion seems to be accelerating faster in the direction of a small part of the northern galactic hemisphere.”  Critics point to contrary evidence from the cosmic microwave background.  “Yet considering that the cosmological principle is one of the pillars of modern cosmology whose fundamental importance is difficult to exaggerate, threats to its credibility won’t be taken lightly,” the article ended.  “If the cosmological principle turns out to be wrong, it would dramatically change the way we look at the world.”last_img read more

Gold Mount vs. V-Mount: Which Is Your Best Choice?

first_imgWhat if You Can’t Decide?Now, what if you’re in a situation where you have V-Mount batteries for your LED lights and Gold Mount batteries for your cameras?For situations where you’re invested in both platforms, fortunately, there are battery adapter plates. With these adapter plates, you can easily attach your Gold Mount batteries to a Gold Mount-to-V-Mount adapter plate (or vice versa) and solve most battery mount issues. However, this method is less preferred, as it provides an additional fail point.How to ChooseUltimately, it comes down to your personal preference and which system works best for you and your workflow. Some filmmakers may like the security and availability of Gold Mounts in U.S. rental houses, while others may prefer the international versatility that comes with V-Mounts.In the end, either battery system is a great choice and will fill the needs of your job. Most importantly, they’ll help you tell and create your projects and stories.Cover image by Kryuchka Yaroslav.Looking more video gear reviews?

Most batteries with enough capacity to power larger cinema cameras offer these two battery mounting choices.However, when you’re looking to purchase your own batteries and, essentially, invest in one of these mounting platforms, it becomes confusing which mount option you should purchase. For the sake of simplicity, it’s typically best to invest all your battery purchases into just one of these formats.Gold MountGold Mount, also known as AB (Anton Bauer) Mount, was created by Anton Bauer fifty years ago. This mount seems to be the battery mount of choice for cinema applications in the U.S. With a secure three gold-stud mounting solution, many regard the Gold Mount as the most secure way to keep your batteries in place while mounted to the camera. This is due, in part, by the fact that to dismount the battery, you have to slide it out from the battery plate sideways. In return, this makes an accidental dismount less likely to occur.Gold Mount batteries also seem to be the most popular option at rental houses in the U.S.V-MountOriginally developed by Sony, the V-Mount battery option is also wildly popular, proven to be a successful battery mounting solution. Just as it sounds, the battery mounts to the battery plate via a v-shaped locking mechanism.According to multiple online forums, many filmmakers express concerns on how secure these batteries are when mounting onto a camera system. This concern is due in part to the fact that these batteries dismount by sliding up. If you’re operating on your shoulder, it is fairly easy to bump the battery up while taking the camera off your shoulder.Personally, I’ve had one instance of a V-Mount battery popping off a battery plate during the middle of a shot. As a result, I lost the shot when the camera immediately powered down. However, many other filmmakers have used V-Mount batteries for years and reported no issues.last_img read more

Cabinet Receives Report of Compensation Committee

first_img The Committee was established to investigate and determine claims for compensation, loss and damage to properties, and to determine the compensation payable to injured persons and to the personal representatives of deceased persons in respect to the events of May 2010. Minister of Justice, Hon. Delroy Chuck, says Cabinet has received the report of the West Kingston Commission Incursion Compensation Committee. Story Highlights Minister of Justice, Hon. Delroy Chuck, says Cabinet has received the report of the West Kingston Commission Incursion Compensation Committee.“Cabinet is likely to consider it very soon, and, hopefully, by early November, that report will be laid in Parliament. It will be the precursor to dealing with all the recommendations of the Tivoli Commission of Enquiry,” Mr. Chuck said as he addressed the Rotary Club of Kingston meeting at The Jamaica Pegasus hotel on October 12.The Committee was established to investigate and determine claims for compensation, loss and damage to properties, and to determine the compensation payable to injured persons and to the personal representatives of deceased persons in respect to the events of May 2010.The establishment of the Committee was one of the recommendations of the Commission of Enquiry Report.Mr. Chuck informed that the report from the Committee indicated that they examined more than a 1,000 claims.“A deadline was set in December of last year for all claims to be made. When the claims started to come in, a number of persons, through the Public Defender, asked for an extension of that time. So, there was a further extension of the deadline, which caused additional files to be submitted, and the Committee agreed to do them,” the Minister said.Meanwhile, Mr. Chuck said recommendations have been made by the Committee for various amounts to be paid out.“A number of them… had to put in a proper matrix for those who got compensation immediately after the event. A lot of them were denied because you might have had two or three persons from the same family applying, and the Committee was able to discern that,” he said.Mr. Chuck said he and Minister of National Security, Hon. Robert Montague, will make presentations in Parliament on different aspects of the Tivoli Report.“The compensation, hopefully, will be paid out soon after, so that this unfortunate matter can be put behind us,” the Justice Minister said.The Committee was chaired by Retired President of the Court of Appeal, Justice Seymour Panton. Other members of the Committee were Ministers of Religion, the Rev. Rennard White and Rev. Herro Blair Jr.Ms. Carlene Larmond, an attorney experienced in litigation, served as Legal Advisor to the Committee.

DHX Media completes strategic review with agency deal for China and Asia

first_imgHALIFAX – DHX Media Ltd.’s shares closed up more than 10 per cent Tuesday after it announced a deal with a division of Global Brands Group to boost distribution and sales of its Peanuts brand in China and elsewhere in Asia as the final step of its strategic review.The children’s entertainment company said late Monday it has also suspended its quarterly dividend, cut staff, and streamlined operations as part of the review it started in late 2017 as the company struggled with debt and poor financial results.Halifax-based DHX said the dividend cut will free up $10 million a year while operational changes will save about $11 million a year that it can put towards debt and future content.The news helped send the company’s share price to as high as $1.76 before closing up 14 cents or 10.3 per cent at $1.50 on the Toronto Stock Exchange. The company’s stock plunged by a third to $1.13 in mid-September to a six-year low after a weaker-than-expected preview of its fourth-quarter results.Going forward, the company will focus on its WildBrain business to capitalize on the rising popularity of YouTube for children, and on using its stable of shows and characters to produce premium original content for major streaming services.“We are well-positioned to enter our next stage of growth, focused on what we identified during the strategic review as the two largest opportunities for kids’ and family content,” said executive chairman Michael Donovan in a statement.The five-year agreement with Global Brands Group subsidiary CAA Global Brand Management Group LLP will see the firm work to increase Peanuts’ presence in Asia by extending the brand’s reach across multiple licensing categories.DHX said China and Asia hold the potential for significant growth of the Peanuts brand. The company said it expects a 35 per cent increase in revenues for the brand in the region over the length of the deal.The company sold a 39-per-cent stake in the Peanuts entertainment business to a Sony Corp. division for US$178 million in May, having bought 80 per cent of the business for US$345 million a year earlier.The strategic review also saw the company appoint a new leadership team including a new chief executive, chief financial officer, operating officer and commercial officer, cut its footprint by 3,150 square metres, and bring some Peanuts agency representation in-house.The completion of the strategic review came as DHX reported a loss attributable to shareholders of $14.1 million or 10 cents per share on $434.4 million in revenue for the financial year ended June 30. That compared with a loss of $3.6 million or three cents per share on $298.7 million in revenue for the previous year.Companies in this story: (TSX:DHX)last_img read more

GST regime will not significantly reduce deficits of state govts

first_imgSingapore: Goods and Services Tax (GST) regime in India is not likely to reduce the deficits of state governments significantly, amid large and growing expenditure mandates for the social sector as well as capital spending, says a report. According to S&P Global Ratings the institutional framework for Indian states is evolving, but there is structural deficits due to persistent revenue expenditure mismatch. S&P Global Ratings credit analyst YeeFarn Phua in the report titled “Public Finance System Overview: Indian States” noted that the passage of the GST bill in 2017 is a major overhaul of tax structure and will help to widen the tax base and improve revenues of state governments. Also Read – Commercial vehicle sales to remain subdued in current fiscal: Icra”However, states will continue to run large deficits because a significant part of this imbalance is from the expenditure side. States are unable to cut expenditures because of large and growing expenditure mandates for the social sector as well as capital spending. Therefore, the revenue-expenditure gap will remain large,” said Phua. Further, policy implementation remains sub-par in India, the report noted. Another significant development in recent years has been the adoption of an amended Fiscal Responsibility Management (FRBM) Act, which forms the fiscal framework, in March 2018, the report noted. Under the amended FRBM Act, the government will target a debt-to-GDP ratio of 60 per cent with the split being 40:20 for central government and states. Further, the government will use fiscal deficit as the key operational target, the report said but added that the FRBM committee lacks the authority to mandate its core recommendations.last_img read more

Turner named AP Player of the Year

After Ohio State was ousted in the NCAA Tournament’s Sweet 16, junior Evan Turner’s dream of hoisting a National Championship trophy this weekend fell by the wayside.However, the Buckeye point guard was in Indianapolis accepting a different trophy.He was named the AP’s Player of the Year Friday, receiving 54 of the 65 votes, and is OSU’s first recipient of the award since Gary Bradds in 1964. Turner led the Buckeyes in nearly every statistical category this season, and averaged 20.3 points, 9.2 rebounds and 5.9 assists.Kentucky’s John Wall finished second with nine votes, and West Virginia’s Deshaun Butler and Notre Dame’s Luke Harangody each received one vote apiece.The award could be the first of several for Turner, not the least of which may come Monday night, when the Naismith National Player of the Year is announced. read more

Prahalis breaks career assists record in victory over the Lady Lions

After struggling through a portion of its Big Ten schedule, the Ohio State women’s basketball team is starting to turn it around. With an 89-67 win over No. 23 Penn State Thursday, the Buckeyes (16-9, 7-6 Big Ten), have won three straight games and continue to climb the muddled conference standings. OSU coach Jim Foster said, in a postgame press conference, that his team has picked up its defensive intensity over the last three games. “At no point in time was I in doubt that we would finish the season strongly,” he said. “Most people come and they see a two-hour blip. We see a lot of stuff going on behind the scenes that we like.” The game was tied 6-6 with 14:53 left in the first half. After a layup by senior center Jantel Lavender, the Buckeyes took the lead and never relinquished it. The Lady Lions (21-7, 10-4 Big Ten), struggled with turnovers, committing 27. They came into the game averaging 17.3 turnovers per contest. Penn State coach Coquese Washington said the turnovers were “the difference in the game.” “We turned the ball over and they’re able to go down and score in transition,” she said. “Ohio State is just a dangerous team in transition.” The Buckeyes turned the Lady Lions’ turnovers into 30 points on offense and had 10 fast break points. Lavender, who was honored before the game for breaking OSU’s career scoring record Sunday, finished with 23 points and 11 rebounds. Former Buckeye guard Katie Smith (1992-96), who held the all-time scoring mark before Lavender, recorded a video message for Lavender. The video played at Value City Arena before the game. “It was really nice that she took time out to congratulate me,” Lavender said. “She held that record for so long so she’s probably like ‘Oh, that’s awesome.’” Lavender helped a fellow Buckeye break a record of her own. Junior Samantha Prahalis set the OSU career assist record after Lavender converted the guard’s signature behind-the-back pass into a turn-around jumper. Prahalis finished the game with 11 assists. With both the scoring and assist records falling in the same week, Foster said he went “out of character” and reflected on what the records meant to him. “It’s going to be very difficult to recruit someone who can break them,” he said. “But, we’ll try.” With 14:40 remaining in the second half, OSU led by 23 after sophomore guard Tayler Hill hit two consecutive free throws. Lavender said Hill’s defense was key for the team. “Our flow started because of our defensive intensity,” she said. “Tayler really set the tone for us on defense and we all fell into place with that.” The Lady Lions cut the OSU lead to 10 three different times in the second half, but couldn’t get the deficit under double digits. “Coach called a 30-second timeout and just said we had to get stops,” Lavender said. “We just started to calm down on defense.” Ohio State’s next game is Sunday at Purdue (17-9, 7-6 Big Ten). The Buckeyes won their previous meeting, 90-67. read more

Monaco announce deal with Atletico Madrid for Lemar

first_imgAS Monaco have announced that they have agreed on a deal in principle with Atletico Madrid to sell Thomas Lemar in the summer transfer windowThe France international has been heavily linked with a move away from Stade Louis II for past year and was narrowly close to sealing a late move to Arsenal in the final day of last summer’s transfer window before opting to remain at Monaco.Lemar was expected to be one of Liverpool’s main transfer targets for this summer, but Atletico have now taken the lead in the race for the 22-year-old’s services.The Europa League winners had an initial bid €60m rejected earlier this month, but it appears that they have made a breakthrough in their negotiations with Monaco.“AS Monaco and Atletico Madrid announce that they have found an agreement in principle for the transfer of Thomas Lemar,” read a statement on Monaco’s Twitter account.Gerard Pique, Neymar, BarcelonaLa Liga Betting: Match-day 4 Stuart Heath – September 14, 2019 Despite it being very early into La Liga season, both Barcelona and Real Madrid have had unprecedented starts to their campaigns.
