Dark Matter as an Escape

first_img(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0 Employing exotic unobservable entities such as dark matter may be an escape from scientific rigor in more ways than one.Recently, the notion that most of the universe is composed of dark matter took an evidential hit.  Live Science said, “A sprawling collection of galaxies and star clusters surrounding our own Milky Way is challenging long-standing theories on the existence of dark matter, the mysterious substance thought to pervade the universe.”  According to a survey of satellite galaxies of the Milky Way conducted at the University of Bonn, dark matter theories fail to account for the arrangement of matter in a region spanning 10 times our galaxy’s diameter. The astronomers extended the impact of their findings to the entire universe:“Our model appears to rule out the presence of dark matter in the universe, threatening a central pillar of current cosmological theory,” said study team member Pavel Kroupa, a professor of astronomy at the University of Bonn. “We see this as the beginning of a paradigm shift, one that will ultimately lead us to a new understanding of the universe we inhabit.“The statement also implies that previous “understanding of the universe” was misguided or absent.Last month Ker Than, reporting for National Geographic News, quoted an astronomer who said the finding of a huge structure of satellite galaxies surrounding the Milky Way puts cosmology “basically in a shambles.”  He referred to his other National Geographic article two weeks earlier that also questioned the existence of dark matter because it wasn’t detected where needed to explain the Milky Way’s halo.  That finding “could provide ammunition for skeptics who argue that the invisible substance is just an illusion,” he said.  About the same time, though, another National Geographic reporter claimed that dark matter particles hit the average human once a minute.Growing questions about dark matter’s existence may be giving rise to a proverb called the “dark matter argument.”  In another context, Maggie McKee at New Scientist reported doubts that the star Fomalhaut has a planet.  A bright spot imaged in a dust disk surrounding the star, imaged by the Hubble Telescope in 2004, had been hailed as a direct observation of an extrasolar planet.  Astronomers were encouraged at the time by the fact that it appeared in a gap in the dust dusk, suggesting that the planet had cleared a path for itself.Now, however, a new study from NASA’s Goddard Space Flight Center has shown that the bright spot might be a dust cloud, not a planet.  Furthermore, simulations shown in a computer animation within the article indicate that gaps in dust disks – even with sharp edges – can form without the presence of a planet.A JPL scientist used the occasion to joke about the escape hatch dark matter theories provide:“I call it the dark matter argument,” says Wladimir Lyra at NASA’s Jet Propulsion Laboratory in Pasadena, California. “There is something you are seeing that you cannot explain, and you blame the gravity of something you cannot see.“Dark energy has also come under scrutiny.  National Geographic asked, is it a kind of “reverse gravity” as usually described?  Perhaps not.  The pressure leading to accelerated expansion of the universe might come from normal old antimatter, well characterized in earth-based detectors.These appear to be dark days for dark matter theories.Philosophers call appeals to unseen, unknown entities “occult phenomena.”  Like spiritually occult things, they are placeholders for ignorance.  But given a name, these placeholders take on a reality of their own, used by scientific shamans to tell the peasants why things are the way they are.For too long, dark matter has been a rhetorical flubber to impress laypeople while escaping scientific rigor.  It’s time to call astronomers to account.  Account for dark matter, or turn on the light.last_img read more

first_imgIndustry experts, policy makers, government and aspiring filmmakers gathered at the South African Film Summit from 4 -5 February 2019 at Skyrink Studios, in Johannesburg. This year’s Summit was held under the theme “Transformation and Innovation in the South African Film/Audio-Visual Industry and the 4th Industrial Revolution. Are we geared for change?”The Summit shines a spotlight on how effectively we are telling South African stories, and explored consensus about “the potential of the industry for nation-building and using the industry as a catalyst for economic growth”.In a statement released by the Department of Arts & Culture, Minister Nathi Mthethwa said: “Policy coordination and coherence is important to ensure there are no unnecessary bottlenecks, contradictions and gaps that will negatively impact on the business environment while simultaneously encouraging investment, particularly from the private sector. Addressing South Africa’s positioning in the film sector, not only in the continent but also globally, is an important one if the country is to compete in the creative economy”.There is no doubt that the Arts & Culture sector is a key player in enhancing the Nation Brand and growing the economy.

How To Never Compromise On Your Goals

first_imgThe amount of time you spend on the very few activities necessary to achieve a goal or a specific outcome is one way to measure how important is the goal, and how serious you are about making it. It is easier to want something than it is to bring that thing to life. More time spent in pursuit of what’s most important is proof that you are willing to do the work necessary to reach your goal. Time spent on things that don’t move you towards what Future You wants, or worse, things that move you further away from your goals, means you are not committed to the outcome. Here is how you never compromise on your goals.Activities Unrelated to Your GoalsTime requires you to choose. If you are not intentional about deciding what to do, you will invariably find yourself caught up in “The Drift,” passively waiting, responding to anything and everything that grabs your attention. Most of what vies for your time will have nothing to do with your goals.The most significant sources of distraction and novelties with the power to pull you into “The Drift,” include your email inbox, the social sites, the things that interest you, and the constant barrage from media designed to capture your intention, mostly with provocative or negative information.Inbox: It is unlikely that what shows up in your inbox has any relevance or value as it pertains to your goals. Most of what you find there are other people’s priorities, their requests, and unbelievably vast amounts of things that provide zero value in trade for your time. What shows up there pulls you in a direction that is almost certain to move you away from the work you need to do to achieve your goal. The overwhelming amount of emails can paralyze you, which is why you should avoid opening your inbox until you have made progress on your goal. The time you spend here is expensive, and it comes at the cost of your goals.Social: The social sites have ushered in a communications revolution, making everyone a content creator at different levels. It has also made each of us more of a content consumer. The sites you frequent most often are designed to keep you on the platform. The more you scroll, the more valuable you are to their business model, a model that depends on you staying online and clicking on advertisements. Welcome to “The Drift,” where one link leads to the next, and you find yourself clicking your way through a more substantial part of your day than would be healthy – at an expense that is much too high.Media: If you care about sports, entertainment, politics, global affairs, or some popular television show, there is no end of options of things that have nothing to do with your goals. Add to this a media that is mostly designed to provoke you, create an emotional response, and capturing your attention, and you have the perfect storm of distractions. Unless you work in media and have goals around these things, the time you spend here to moves you further away from your goals.You can have your goals, or you can have your distractions. You cannot have both.Activities Necessary to Reach Your GoalsBecause time requires you to choose how you will use it, you have the power to decide what you will do, and more importantly, what you will not do with your time. The best decision is to let Future You, the better you that you imagine and are working towards creating, make the decision. Future You is a more disciplined version of yourself, you that wants something more, that is becoming something more.There are very few activities necessary for reaching your goals. These few things must dominate your time. The greater your investment of time, provided you are competent, the more confident you will achieve your goal. You can think of this as a metric we might call “time against goal.”If you want to reach your sales goal, the time spent prospecting and in client meetings is one way to measure your effort, your willingness to do the right work, and the likelihood you reach your goal. Time spent on things that do not produce new opportunities or allow you to win them deprive you of time and move you further away from your goal. One of the most common ways salespeople miss their goal is because they don’t spend enough of their time selling. They don’t sell enough, because they very literally don’t sell enough.If you want better relationships, spending time with the people that matter most is a metric that indicates how important that goal is to you. Communication is easy. Real communication, your full focus and attention, and your presence is more complicated. There may be no bigger gift one can give another than their full presence. If you seek work-life balance, think less in terms of hours and more in terms of hours of presence.Whatever your goals, the work necessary to achieve it needs to dominate your calendar. When you allow something less than your highest priorities, command your time and energy, it takes more time to reach your goals—if you reach them at all.Values-Based DecisionsYour goals require that you make values-based decisions. You have to decide that “this” is better than “that.” All things cannot be equal, and because time requires you to choose, you have to determine your priorities, without which, you will drift.Without clarity about what is most important, you allow everything to come into your world, make demands on your time, your attention, and your energy, while your goals and outcomes go without the time that should be dedicated to what you want, and not what shows up.Everything you decide to do—or not do—should have to pass through filters tight enough to deprive those things that are meaningless while letting through what is critical to what you want in the future.

Striking medical students threatened with legal action

2 black men arrested at Starbucks get an apology from police

first_imgPHILADELPHIA – Rashon Nelson initially brushed it off when the Starbucks manager told him he couldn’t use the restroom because he wasn’t a paying customer.He thought nothing of it when he and his childhood friend and business partner, Donte Robinson, were approached at their table and were asked if they needed help. The 23-year-old entrepreneurs declined, explaining they were just waiting for a business meeting.A few minutes later, they hardly noticed when the police came into the coffee shop — until officers started walking in their direction.“That’s when we knew she called the police on us,” Nelson told The Associated Press in the first interview by the two black men since video of their April 12 trespassing arrests touched off a furor around the U.S. over racial profiling or what has been dubbed “retail racism” or “shopping while black.”Nelson and Robinson were led away in handcuffs from the shop in the city’s well-to-do Rittenhouse Square neighbourhood in an incident recorded on a white customer’s cellphone.In the week since, the men have met with Starbucks’ apologetic CEO and have started pushing for lasting change at the coffee shop chain, including new policies on discrimination and ejecting customers.“We do want to make sure it doesn’t happen to anybody again,” Robinson said. “What if it wasn’t us sitting there? What if it was the kid that didn’t know somebody that knew somebody? Do they make it to jail? Do they die? What happens?”On Thursday, they also got an apology from Philadelphia police Commissioner Richard Ross, a black man who at first staunchly defended his officers’ handling of the encounter.“I should have said the officers acted within the scope of the law, and not that they didn’t do anything wrong,” Ross said. “Words are very important.”At a news conference, a sombre Ross said he “failed miserably” in addressing the arrests. He said that the issue of race is not lost on him and that he shouldn’t be the person making things worse.“Shame on me if, in any way, I’ve done that,” he said.He also said the police department did not have a policy for dealing for such situations but does now and it will be released soon.Nelson and Robinson said they went to the Starbucks to meet Andrew Yaffe, a white local businessman, over a potential real estate opportunity. Three officers showed up not long after. Nelson said they weren’t questioned but were told to leave immediately.Yaffe showed up as the men were being handcuffed and could be seen in the video demanding an explanation for the officers’ actions. Nelson and Robinson did not resist arrest.“When you know that you did nothing wrong, how do you really react to it?” Nelson said. “You can either be ignorant or you can show some type of sophistication and act like you have class. That was the choice we had.”It was not their first encounter with police. But neither had been arrested before, setting them apart from many of those they grew up with in their gritty southwest Philadelphia neighbourhood.Nelson and Robinson spent hours in a jail cell and were released after midnight, when the district attorney declined to prosecute them.Nelson said he wondered if he’d make it home alive.“Any time I’m encountered by cops, I can honestly say it’s a thought that runs through my mind,” Nelson said. “You never know what’s going to happen.”Starbucks has said the coffee shop where the arrests occurred has a policy that restrooms are for paying customers only, but the company has no overall policy. The men’s attorney, Stewart Cohen, said they were illegally profiled.The arrests prompted protests at the Starbucks and a national boycott. Kevin Johnson, CEO of the Seattle-based company, came to Philadelphia to meet with the men, called the arrests “reprehensible” and ordered more than 8,000 Starbucks stores closed on the afternoon of May 29 so that nearly 175,000 employees can receive training on unconscious bias. Starbucks has not identified the employee who called police.Robinson said that he appreciates the public support but that anger and boycotting Starbucks are not the solution.The men said they are looking for more lasting results and are in mediation with Starbucks to make changes, including the posting in stores of a customer bill of rights; the adoption of new policies on customer ejections and racial discrimination; and independent investigations of complaints.“You go from being someone who’s just trying to be an entrepreneur, having your own dreams and aspirations, and then this happens,” Nelson said. “How do you handle it? Do you stand up? Do you fight? Do you sit down and just watch everyone else fight for you? Do you let it slide, like we let everything else slide with injustice?”___Whack is The Associated Press’ national writer for race and ethnicity.

Modis rallies in Kolkata Siliguri on April 3

first_imgKolkata: Prime Minister Narendra Modi will address two rallies – one at north Bengal’s Siliguri and other at Kolkata’s Brigade Parade Ground — on April 3 ahead of the Lok Sabha polls, a party leader said on Sunday. “His first public meeting will be in Siliguri at 1 p.m. and then he will attend a rally at Brigade Parade Ground at 3 p.m.,” BJP leader Mukul Roy told reporters. He said no political party had earlier shown the courage to organise a Brigade rally as well as a rally in North Bengal in one day. Also Read – Uddhav bats for ‘Sena CM’ “We will successfully organise both the rallies in the time frame of just 10 days. People of north Bengal will come to Siliguri while supporters and activists will join the Brigade rally,” he said. Modi held three rallies in Bengal’s Thakurnagar, Durgapur and Jalpaiguri in February where he launched a scathing attack on the Mamata Banerjee government, blaming it for violence, corruption and extortion. Permission for party’s “Save Democracy” programme was denied by West Bengal’s ruling Trinamool Congress and a planned rally at the iconic Brigade could not be organised earlier because it was initially part of the Save democracy programme, Roy said. The Bharatiya Janata Party holds two Lok Sabha seats in the state and hopes to win at least 22 of the 42 Lok Sabha seats. West Bengal will see seven-phased polling from April 11 to May 19.last_img read more

Ohio State mens soccer team returns home for match against another ranked

Then-sophomore defender Austin Bergstrom (25) kicks the ball during a game against Michigan in the first round of the Big Ten Tournament on Nov. 9 at Jesse Owens Memorial Stadium. OSU won, 1-0.Credit: Lantern File PhotoComing off a three-week road swing, the Ohio State men’s soccer team will prepare to host its first conference game this weekend.After playing to a 3-3 double-overtime draw against in-state rival No.11 Akron on Wednesday, the Buckeyes are scheduled to take on another ranked opponent in No. 13 Penn State at 3 p.m. on Sunday at Jesse Owens Memorial Stadium.Before its game against Akron, OSU was on a four-game losing streak, trying to find its momentum. Despite the team’s disappointing start to the season, it did not let it affect its mindset going into Wednesday’s game as the Buckeyes came from behind to tie the game against Akron.“We would have liked to get the win,” senior midfielder and co-captain Zach Mason said. “But I think it showed a lot about the heart this team has and the character to bounce back from a tough stretch and play a ranked opponent toe-to-toe; so I think we’re headed in the right direction.”OSU proved to be able to keep up with a ranked competitor, but the Buckeyes will face another heavy challenge as they prepare to face No.13 Penn State.“They are very solid and organized all over the pitch, and they have a few attacking plays where they can unlock the door and score a goal,” senior defender and co-captain Liam Doyle said. “So as hard as they are to beat, they’re also dangerous at getting a goal or two, so we have to be on our game against them.”Mason said that the team would really have to take its chances this weekend because it is going to be a 90-minute battle.Despite the challenge OSU will likely face, Doyle said the team would like the fans to come out and support the team on Sunday.“I think Ohio State and Penn State have a rivalry in a lot of sports and what else is there to do on Sunday afternoon a 3 p.m.?” Doyle said. “Might as well come out in the nice weather and enjoy the game.”About the Nittany LionsPenn State comes into Sunday’s game after defeating 10th-ranked Indiana 1-0 on Sunday in University Park, Pennsylvania. Penn State stands at 4-1-1 overall and 1-0-0 in Big Ten play. Freshman forward Marc Curran leads the team with six goals, while senior midfielder Brian James has three goals and one assist. Senior goalkeeper Matt Bersano is 4-1-1 overall with a 0.48 goals against average and .880 save percentage and has played a total of 470 minutes.What’s next?Following Sunday’s action, the Buckeyes are scheduled to take on Dayton at 7 p.m. on Friday at Jesse Owens Memorial Stadium. read more

Deschamps has prepared France for Cavani

first_imgFrance boss Didier Deschamps insists that he has prepared his side for facing Edinson Cavani ahead of their quarter-final clash with Uruguay, regardless of whether he plays or notThe Paris Saint-Germain forward was the hero for Uruguay in their previous knockout round against Portugal, where his stunning goals proved to be the difference in the 2-1 win over the European champions.However, Cavani’s heroics came at a price and he was seen limping off the pitch towards the end of the game with a calf injury with some assistance from Cristiano Ronaldo.Since then, Cavani had missed three consecutive training sessions with the Uruguay squad as of Wednesday and did some minor work on Thursday.Although he still appears to be a likely doubt for their last-eight match against France.But Deschamps is not taking that for granted.Kylian Mbappe, Paris Saint-GermainKylian Mbappe could return to PSG training next week Andrew Smyth – September 12, 2019 Paris Saint-Germain confirmed that Kylian Mbappe could make a return to training to next week as he continues to recover from a hamstring injury.“I am preparing my team for Cavani. Whether he plays or not, we will know tomorrow. If he doesn’t play, (Oscar) Tabarez has other options. I have prepared my team keeping different options in mind,” said the French coach, according to Hindustan Times.The 49-year-old feels that France must put their thrilling 4-3 win over Argentina behind with Uruguay set to be an entirely different challenge altogether.“This Uruguayan side has a different profile from Argentina. We have to be very patient. They are extremely well organised in defence,” he said.“If they need 10 players to defend, they will do that. When they don’t have ball possession, they know what to do; everybody defends, even the striker defends.”But Deschamps knows there is more to Uruguay than their defence, he added: “They can counter-attack very quickly. We must also bear in mind that this is a team that knows how to take advantages of set-pieces.”Uruguay and France will face off at the Nizhny Novgorod Stadium today at 16:00 (GMT +2).last_img read more
