Globular Cluster Origins: Where Do We Go From Here?

first_imgThe simple explanation of globular clusters as bundles of ancient stars seems to be in a state of crisis, though the authors of a paper in the Jan. 1 issue of Nature1 try to keep a stiff upper lip.  They begin, “Nearly a century after the true nature of galaxies as distant ‘island universes’ was established, their origin and evolution remain great unsolved problems of modern astrophysics.”    For one thing, how could globulars survive all the tumult?  “Recent advances in our understanding of the globular cluster systems of the Milky Way and other galaxies point to a complex picture of galaxy genesis driven by cannibalism, collisions, bursts of star formation and other tumultuous events.”  It appears now that they cannot assume that the high metallicity (content of atoms heavier than helium) in cluster stars is an indication of old age.    Current thinking is a debate between competing models dealing with uncooperative observations.  After showing strengths and weaknesses of contenders, they ask, “Where do we go from here?”  Much work remains to be done, they admit.  Although they offer some promising areas of research, it may be that the origin and evolution of each galaxy may be unique:Detailed spectroscopic and photometric observations of the most massive galaxies in dense environments show that their globular cluster populations are generally old and coeval to within a couple of billion years.  But the age distribution of globular clusters remains an open question, as several recent studies have found a wider spread of globular cluster ages in some galaxies, including the presence of some intermediate-age metal-rich clusters.  The findings to date suggest a complex picture of globular cluster formation in galaxies, with the formation histories of no two galaxies being exactly alike.Not to end on a minor chord, they triumphantly promise that the quest for understanding galactic evolution marches on:These are exciting times in the study of extragalactic globular cluster systems.  Disentangling the myriad processes that may have contributed to the formation of nearby galaxies is a formidable challenge, but the potential reward is spectacular: a glimpse into the evolutionary histories of individual galaxies.See also the Oct. 5 entry on globular clusters.Michael J. West et al., “Reconstructing galaxy histories from globular clusters” (review article), Nature 427, 31 – 35 (01 January 2004); doi:10.1038/nature02235.We don’t know where we are, we don’t know how we got here, the territory is far more complex and formidable than we thought, and we don’t know where to go from here, but at least we can imagine how nice it would be to find our way some day.  How much do you trust this bunch?(Visited 34 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Sorry, Robert Scoble, The Least Of Microsoft’s Problems Is Its “Cool Factor”

first_imgMatt Asay Related Posts 8 Best WordPress Hosting Solutions on the Market Tags:#Apple#Google#innovation#Microsoft#robert scoble Top Reasons to Go With Managed WordPress Hosting A Web Developer’s New Best Friend is the AI Wai… Leaving aside whether Scoble knows anything about coolness (Note: The author used to drive a minivan, and so has no claims on coolness, either), it’s not clear at all that Microsoft ever was cool to begin with. Not in the ways that Scoble seems to prize.The Wrong Definition Of “Cool”For example, in an interview with Fairfax Media, publisher of The Age, Scoble makes a case for money-losing gizmos as a sign of innovation:[Google Glass] might never make a dollar but it’s new, it’s interesting [and] it causes conversations. If you’re an innovator, you push the future ahead. You don’t care whether it necessarily makes a dollar.I’m not sure this view holds much water. It’s certainly not true of Apple, a company with a culture and view on innovation that differs markedly from Google’s. Apple only releases products that it believes have a serious commercial potential. It’s not in the innovation for innovation’s sake business.Even Google isn’t as wild and crazy as Scoble seems to believe. It is absolutely true that the company does “out there” projects like Google Glass and its self-driving car, it’s equally true that Google decommissioned its Labs projects because Google “believe[s] that greater focus is crucial if we’re to make the most of the extraordinary opportunities ahead.”Like ads constantly in your range of vision. Or a car that steers you toward advertisers. Or launching WiFi balloons to give Internet access to those who can’t afford it… but can still click on ads. (See the theme?)Microsoft’s Problem Is MoneyBesides, Microsoft has its own brand of money-losing innovation. It’s called Microsoft Research, and it spends billions of dollars each year creating Star Trek-like holodecks (“magic wall”), among other things that probably will never see the light of day (or market).No, Microsoft’s problem is not that it lost its coolness. It never had it. Who thinks Office or Windows are “cool?” Useful, yes, but cool? Not my definition of cool, anyway.What it had, and what has largely inhibited its relevance, is two gargantuan cash cows—Windows and Office—that have kept the company profitably mired in the past. Microsoft, in other words, faces an Innovator’s Dilemma. It can’t stand the thought of cannibalizing the two products that made it immensely successful.But it needs to. Microsoft remains CIOs “most indispensable” mega-vendor, according to a Piper Jaffray report. But this won’t last if Microsoft can’t move these enterprises into the future of computing, something that is at risk so long as Apple and Google control mobile. But “coolness” won’t solve this problem.I’m sure Scoble knows this, but his talk of “cool” obscures the real issue. Microsoft doesn’t have to be cool to thrive. It just needs to unshackle its organizations from orbiting around Windows and Office. The XBox team did this. So has Azure, to some extent. More is needed. Why Tech Companies Need Simpler Terms of Servic… Microsoft has many problems. I’m not sure “cool” is one of them. Robert Scoble, who makes a living showering with Google Glass and blogging about startups (for a company that is neither Google nor a startup), disagrees. For him, Microsoft has lost its mojo. Its “cool factor.”This from the man who does interviews wearing goofy sci-fi glasses.last_img read more

Urban Meyer Claims Ohio State Is The Real “DB U”

first_imgurban meyer is now a spokesman for bob evansThe debate rages on. Earlier this month, players from LSU, Florida, Oklahoma State and other schools got into a number of Twitter arguments regarding which program should be considered “D.B.U” – meaning, which school produces the best defensive backs when it comes to NFL success. Well, there appears to be a new entrant, and it has a fairly decent spokesman. Ohio State’s Urban Meyer is now claiming that his school is the real “D.B.U”, and he’s got an NFL.com article to back up his claim.pic.twitter.com/IhLH9SdnoC— Urban Meyer (@OSUCoachMeyer) May 28, 2015The piece, written by Chase Goodbread, lists former Buckeyes Donte Whitner, Antoine Winfield, Chris Gamble, Nate Clements, Shawn Springs and Will Allen as examples as to why he believes Ohio State is tops.Of course, these kinds of titles have been created purely for entertainment purposes. That being said, it is interesting to watch players, coaches and analysts vouch for who they think deserves the crown. Is Meyer right?last_img read more

Tim Hortons signs franchise agreement with Cartesian Capital to expand to China

first_imgTim Hortons plans to open more than 1,500 of its coffee-and-doughnut shops in China over the next decade.The expansion seeks to capitalize on the country’s burgeoning coffee culture and is the latest international location for the coffee chain aiming to become a global brand.“China’s population and vibrant economy represent an excellent growth opportunity for Tim Hortons in the coming years,” the brand’s president Alex Macedo said in a statement.The chain signed a master franchise joint venture agreement with private equity firm Cartesian Capital Group for it to develop and open the restaurants. Financial terms were not immediately available.In 2012, Cartesian Capital partnered with Tim Hortons parent company Restaurant Brands International, which also owns Burger King and the Popeyes brand, and the Kurdoglu family to develop the burger chain in China. There are now more an 900 Burger King restaurants in China.City dwellers, especially young people and white-collar employees, in China increasingly drink coffee and have helped the cafe industry see strong growth, according to market-research firms.The turn to caffeine partly comes from lifestyle changes, people earning more money and more people living in cities, according to the firms.Consumers choosing coffee has helped fuel coffee chains’ expansion into China.Starbucks had 3,300 stores in 141 cities in China as of May and plans to total 5,000 by 2021. China is its fastest growing market and it opens a new store in the country every 15 hours.Whitbread, which operates Costa Coffee, has 449 of the coffee chain’s shops in China and plans to have 1,200 by 2022, according to its most recent annual report.While Tim Hortons is confident it can appeal to the Chinese, it’s latest international expansion plans haven’t convinced everyone.BMO Capital Markets analyst Peter Sklar said the expansion presents a growth opportunity for the company.“However, we believe there is significant uncertainty about whether the international rollout of the Tim Horton’s brand will ultimately be successful,” he wrote in a report.Tim Hortons has previously announced plans to expand to Spain, Mexico, Great Britain and the Philippines.“We remain concerned about its potential for success given RBI’s challenged expansion into the U.S. in the past,” Sklar wrote.The coffee chain is not as well known outside Canada than RBI’s fast-food brand Burger King, he said, adding to the uncertainty.Tim Hortons has more than 4,700 restaurants in Canada, the United States and around the world.Follow @AleksSagan on Twitter.Companies in this story: (TSX:QSR)last_img read more

China denies its action amounted to protecting violent Islamic groups

first_imgBeijing: Defending its repeated attempts to block the listing of JeM chief Masood Azhar as a global terrorist by the UN, China on Friday refuted US allegation that its action amounted to protecting violent Islamic groups from sanctions.US Secretary of State Mike Pompeo on Wednesday denounced China of its “shameful hypocrisy” toward Muslims, saying China abuses more than a million Muslims at home, but on the other it protects violent Islamic terrorist groups from sanctions at the UN.” Also Read – Uddhav bats for ‘Sena CM’Pompeo had said it in apparent reference to China’s move to block India’s proposal at the United Nations to designate Jaish-e-Mohammad chief Azhar as a global terrorist. Reacting to this, Chinese Foreign Ministry spokesman Geng Shuang told a media briefing here on Friday that if that is so, the country that had put most technical holds in the 1267 Al Qaeda Sanctions Committee of the Security Council should have been sheltering more terrorists. At the UN Sanctions committee, the practice of putting technical hold is in line with the rules of the Committee, he asserted. Also Read – Farooq demands unconditional release of all detainees in J&KWithout directly referring to the US, Geng said, “If a certain country accuses China of sheltering terrorists by putting technical hold, does that mean all the countries that put such holds are sheltering terrorists? If this makes sense then shall we say the country that put most hold is the biggest shelter of terrorists? China has so far blocked the move four times in recent years. It recently blocked a US, UK and France resolution in the counter terrorism 1267 committee with “technical hold” saying that it provides time and space for the relevant parties to hold talks after the Pulwama terrorist attack. Following this, the US has directly moved a resolution in the UN Security Council on Thursday to blacklist Azhar which China said amounted to undermining the 1267 committee. Defending China’s move to block Azhar’s listing, Geng said, China put forward a technical hold with a purpose of conducting in-depth assessment so as to give enough time and space for the dialogue and consultation between parties. China is in communication with all parties to seek a settlement through dialogue. We hope this will be a common goal of all the members of the UNSC. Asked about Pakistan rejecting the evidence put forward by India on the Pulwama terrorist attack, he said, the 1267 committee has detailed and clear stipulation and requirements on the listing issue. What China has done is in line with the requirement of the UNSC and rules and procedures of the committee. We are always working in a constructive manner and stay in communication with the relevant parties and seek a proper solution. “It is improper to reveal to you the detailed discussions, he said. To another question whether China is preparing to defend its stand in the UNSC when the latest US resolution would come up for discussion, Geng said, China stayed in close communication with all parties on the listing issue. We will act in a responsible and a constructive manner to participate in the discussion at the committee. We also hope to work with various parties to seek a proper settlement to the issue , he said. China on Thursday asked the US not to complicate the listing of Azhar as a global terrorist by “forcefully moving” a resolution directly in the UNSC, undermining the authority of the UN’s anti-terrorism committee. “This is not in line with resolution of the issue through dialogue and negotiations. This has reduced the authority of the Committee as a main anti-terrorism body of the UNSC and this is not conducive to the solidarity and only complicates the issue. “We urge the US to act cautiously and avoid forcefully moving forward this draft resolution,” Geng said.
