The results are available in Physical Review Letters, in a piece titled “Critical Velocity for Superfluid Flow across the BEC-BCS Crossover.”In ultracold gases, the BEC-BCS crossover basically addresses how superfluidity in bosons transforms into superfluidity in fermions. At issue, says Ketterle, is how fermions can be made to interact very strongly so that superfluidity occurs at higher temperatures. Furthermore, an improved understanding of the pairing mechanism can lead to the developments of new materials that could serve as superconductors. “Bare electrons repel each other,” says Ketterle, “unless there are many other particles around them which can lead to some attraction and to pairing. Once paired, fermions act as bosons.” So far, the group has studied fermionic atoms with attractive interactions, but in the future, they hope to see how to pair fermions, which repel each other, to resemble the electrons.“These are important issues,” Ketterle explains. “Superfluids and superconductors have many possible applications. We use them now, but if we understood them even better, more applications could open up.” He illustrates: “Imagine having a superconducting power grid where energy flows without resistance or developing better magnets for MRIs.” These are only a couple of the applications that scientists can think of now. “A better understanding of superfluids may lead to the design of new materials in the future.”But for the here and now, Ketterle’s team has managed to create conditions that use tuning to control the pairing of fermions. “When we modify the external magnetic field, we can loosen up the binding between the particles until they reach a point where two of them are not bound at all, but many of them still are.”The MIT team studied the critical velocity only in the center of the atom cloud, avoiding the limitations of inhomogeneous density. They moved an optical lattice (an interference pattern between two laser beams) through the superfluid. The group found that the critical velocity is highest when molecular pairs transform into Cooper pairs “in which attractive forces are about to support a molecular state.” Ketterle expects other studies to follow — and to perform additional quantitative tests of the theoretical predictions. “We have seen that this system allows us to study the breakdown of superfluidity,” Ketterle says. “The ultimate goal is to use our new tools and methods to find new regimes of superfluidity, to find out for what interactions and in what kind of geometry superfluidity is most robust,” says Ketterle. “This is an exciting frontier. We are able to study superfluids over the whole range of interactions throughout the crossover. This is the latest advance toward understanding superfluidity and superconductivity.”Copyright 2007 PhysOrg.com. All rights reserved.

Nigel Leck’s creation is @AI_AGW (also known as Turing Test), and the script searches the Twitter site for hundreds of phrases he believes tend to be used by those who think global warming is not occurring, or who think it is occurring but is not anthropogenic or entirely anthropogenic. When the script finds one of the phrases it then “tweets” a response from an extensive database of countering phrases.The return tweets are selected to match the phrases found so, for example, tweets about global warming occurring on Mars or Neptune will produce a response suggesting this does not prove the sun is warming and producing Earth’s global warming. Tweets often contain a link to a scientific source or a video refuting the argument.Leck said he originally wrote many of the rebuttals himself, but he has now extracted many from a university source, but one which he will not identify. Some of the responses relate to religion, which is where Leck says debates with the chatbot often end up.The tweets are not identified as autoresponses, although the name provides clues, and Leck said many people receiving them continue their “conversations” for hours or days, which is possible because the program selects from a range of responses and does not reply the same way each time.Leck said if the program “argues them into a corner,” there tends to be two “crowds”: one who resort to the “God created it that way” final response, and a second group Leck calls “skeptics so unyielding they won’t be swayed by any amount of argumentation.”One problem with the chatbot is its inability to spot sarcasm, which is often rife during extreme weather events such as heat waves, when many tweets suggest it’s so hot outside it’s “a good thing global warming is a myth,” or cold snaps, when tweets sarcastically suggest global warming is a hoax. Leck said the program includes an algorithm that enables it to learn to recognize such false positives, but that he promptly apologizes when the chatbot is found to have irritated Twitter users who are not arguing about climate change, and whitelists their accounts. Leck said he intends to expand the program at some time by enabling it to cull new phrases from tweets from others (presumably also non-scientists like Leck) debating with those skeptical of climate change arguments. He said this would allow it to argue “into the ground” the increasing number of what he called “anti-science tweeters who are unwilling or unable to look up the proper scientific literature themselves.” (PhysOrg.com) — A software developer has created a “chatbot” program for Twitter to automatically detect set phrases associated with arguments put forward by those skeptical of anthropogenic global warming, and to send automated replies of set phrases debunking their arguments.

Explore further Acacia savanna south of Fada N’Gourma, Burkina Faso. Image: Wikipedia. (PhysOrg.com) — Two recent studies have found that environmental changes can bring previously stable forests and grasslands to tipping points that produce sudden large-scale and sometimes irreversible changes in which forest can become savanna and vice versa. These findings challenge previous assumptions that changes to natural systems occur continuously and smoothly. In one study published in Science, scientists in The Netherlands, led by Marina Hirota of Wageningen University, studied NASA satellite data on forests (around 80% trees), savanna (around 20%) and treeless areas (about 5% tree cover). The group found that intermediate regions were rare, and that the rainfall was the primary factor determining which landscape would be found. The researchers also found that big shifts can suddenly occur in the type of landscape, rather than the slow, smooth transition expected.In a US/South African study also published in Science, researchers led by A. Carla Staver of Princeton University found that the degree of tree coverage generally depends on rainfall and seasonal changes, but in areas where the rainfall level is intermediate (1000-2500 mm annual) and seasonal changes are mild, fire becomes the most important factor in determining whether forest, grassland or treeless landscapes were likely to predominate. They found a tipping point at 40-45% tree coverage: below this fires spread rapidly, and above this the increased tree coverage slows down the spread of fires.Both groups studied data collected by NASA’s Aqua and Terra satellites, which use MODIS (Moderate Resolution Imaging Spectroradiometer) instruments to detect vegetation coverage and determine the type of vegetation prevailing. They both concentrated on areas thought to be least affected by human activity, including subtropical and tropical parts of Australia, South America, and Africa.Prevailing theories of ecological development suggest that if the rainfall on a savanna gradually increases, the number of trees should also gradually increase until the region becomes a forest. The new studies suggest instead that the savannas remain grasslands as the rainfall increases until a tipping point is reached, at which time the savanna suddenly switches to a fully-forested area instead. Such sudden changes have been noted on a local scale but until now it had not been known that they occurred on a global scale.The findings could have implications for people whose livelihoods depend on their landscape remaining the same, since it could change rapidly, which would require people to also adapt quickly to the changes. To assist them, Hirota’s team has developed what they call resilience maps identifying regions close to the tipping point. The two studies could also help to refine climate change models, which currently assume the transition between grassland and forest is gradual and depends mainly on rainfall and temperatures. © 2011 PhysOrg.com Study identifies two types of savannas Citation: Forest and savanna can switch quickly (2011, October 14) retrieved 18 August 2019 from https://phys.org/news/2011-10-forest-savanna-quickly.html This document is subject to copyright.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org)—Advanced Micro Devices (AMD) on Monday announced its launch of 16-core Opteron 6300 server chips. This is its newest series in server processors based on the chip designer’s Piledriver core architecture. The Opteron 6300 family has models with four, eight, 12 or 16 processor cores (up to 16 cores per socket for scaling in “thread-intensive” environments). AMD says the processors are designed for “virtualized server platforms that are central to private and public cloud deployments, big data systems and high-performance computing (HPC) clusters.” This is a sequel to its 6200 series; the 6300 series “Piledriver” chips show better speed than the 6200 series. More information: Press release Quad-Core AMD Opteron Processor Family Expands with New Low-Power Options The speed improvement is 40 percent—up to 40 percent higher performance per watt than the prior generation, according to AMD. That makes the new 6300 launch especially suitable for businesses running large-scale software systems, said AMD.Data centers are attracted to many-core processors for their needs, and the 6300 family should be attractive at data centers with heavy workloads. Dell thinks so. A spokesperson said, in the AMD press release, that the 6300 series can offer its customers performance gains beneficial for cloud computing, big data, and high growth data-center applications. Technical details include AMD Virtualization technology for virtualized environments, up to four memory channels with up to 1866 MHz memory, and support for ultra-low voltage 1.25v memory.Servers from Dell and HP based on the AMD Opteron 6300 Series processors will be available by the end of the year. AMD said the AMD Opteron 6300 Series processor will also be leveraged as part of a supercomputing deployment at Indiana University.The school’s earlier Big Red supercomputer is being replaced with Big Red II, for high-performance parallel computing, capable of performing one quadrillion floating-point operations per second (1 petaflop). The school provided details on the Big Red II computing environment. There will be two AMD X86-64 processors with 16 cores each, the nodes providing 32 cores and 64 GB of memory per node; plus GPU-enabled compute nodes, containing one AMD X86-64 processor and one NVIDIA GPU, with these nodes providing 32 GB of memory. All compute nodes are connected through the Cray Gemini interconnect.The 6300 launch this week follows AMD’s October “ambidextrous” announcement that it will be taking a new strategic move to bridge x86 and ARM processors for cloud and data center servers. The company said its goal in doing so is to offer desirable performance-per-watt for dense cloud computing solutions. The first 64-bit ARM-based processors for servers are expected in 2014.

3D map of the cosmic web at a distance of 10.8 billion light years from Earth. The map was generated from imprints of hydrogen gas observed in the spectrum of 24 background galaxies, which are located behind the volume being mapped. This is the first time that large-scale structures in such a distant part of the Universe have been mapped directly. The coloring represents the density of hydrogen gas tracing the cosmic web, with brighter colors representing higher density.

Also another team of researchers in the U.S. took another look and found that the increase of CO2 in the atmosphere is lower than predicted because of plants. And that top secret shuttle-looking plane the U.S. Air Force has been testing landed at an Air Force base in southern California after flying for nearly two years, inviting widespread speculation as to its purpose.In more practical news, scientists in Singapore have come up with a new type of battery that can be recharged up to 70 percent in just two minutes—and will last up to 20 years. And a team at Siemens announced that they’d developed a drive system that saves space and weight in electric cars—allowing the cars to go farther on a charge. Unrelated but still remarkable, a team of researchers in the U.K. announced that they had found what they believe to be the underlying cause of 40 per cent of pre-term births—if they can find a cure, it might mean drastically reducing the number of deaths of babies due to premature birth.And finally, it turns out that depression in some people may be related to the way gut bacteria helps keep the brain healthy–and how it could play a role in the treatment of depression. Have we been causing our own depression by killing off our gut biome with antibiotics? New research suggests that’s entirely possible. © 2014 Phys.org (Phys.org) —It was an interesting week for physics as scientists built the first map of the hidden universe—astronomers led by a team with the Max Planck Institute in Germany created the first 3D map of the universe depicting things just three billion years after the Big Bang. Also, Lockheed Martin revealed new details about its pursuit of a compact fusion reactor concept, announcing they are on the fast track to developing what they describe as the ultimate power source and predicting they’ll have a prototype in just five years. And a team of physicists from China and Singapore conducted quantum tests that strengthen support for EPR steering—it concerns particularly strong types of entanglement in which the two systems are not just correlated, but are correlated in a specific direction.

A break from the buzz—bees go silent during total solar eclipse In this new effort, the researchers sought to better understand how creatures such as birds and insects respond to atypical periods of darkness such as a total solar eclipse. To that end, they gained access to data from 143 weather stations that had captured the activities of multiple birds and insects in different parts of the United States during the August 21, 2017, solar eclipse. They note that due to the short lifespan of birds and insects, none of them would ever have experienced an eclipse before. Thus, the sudden darkness would present an unexpected change in their environment.In looking at the Doppler radar data and analyzing it using machine-learning programs, the researchers were able to establish movements of flying species from near the ground to approximately three miles up in the air. They report seeing unusual activity up to 50 minutes before the eclipse reached totality—many of the flying creatures began returning to ground or other perches. This was particularly so for those flying at high altitudes. The researchers suggest that it seems reasonable to attribute the change in activity to the creatures responding as they would to a storm—seeking shelter is a natural response to weather conditions that can prove deadly for small flying creatures.The researchers also found something they thought was strange: A group of flyers, likely birds, changed their behavior just before totality, suddenly taking flight and quickly settling back to their perches once again. They suggest the reason was because the birds had become confused, at one moment thinking that normal darkness had arrived, only to discover that it was something else.The researchers are planning to collect even more data the next time around—in 2024, a total solar eclipse will once again pass over major parts of the continental United States. They hope more precise radar data might be able to differentiate between animals. This document is subject to copyright.

As I heard the horror story about the girl who was gang raped, I felt a stir in my soul. I felt angry and frustrated for all those girls who aspire to improve their lot in life without hiding behind a man. It is truly a heart-wrenching story that has sparked a revolution.From my experiences from across the globe, I have noticed that India is predominantly an orthodox society. Dress code for women is still a issue in India. The show of legs or cleavage by girls is considered provocative and even the advent of Facebook and the android phone has done little towards improving the image of women. Wearing shorts or tight tops is still frowned upon. It is a common sight to see a group of guys leering at a shapely girl wearing a pair of shorts and a tee. Also Read – ‘Playing Jojo was emotionally exhausting’So why does this kind of behaviour happen?One of the reasons may be increased Westernisation which has helped this country to catch up with the rest of the world in many ways in less than 20 years. The mindset some sections of males might have not adjusted to this rapid evolution.In recent times, however, public places too have evolved. With the advent of the malls, things have become a bit better as they act as ‘safe zones’ for modern women. Girls feel free to wear tight clothes and shop their favourite high street brand without the fear of being teased. However, once you exit, the streets outside are completely different story. With regard to the words ‘safe zone’, what got me introspecting was an explanation given to me by a friend who relocated to New Delhi from New York. Also Read – Leslie doing new comedy special with NetflixIn her words ‘it is ok for a women to wear anything in Delhi provided she travels in her own car and goes to the right places’. This sounded discriminatory. What about all the lakhs of women in Delhi who live alone and need to travel by public transport? Will they never enjoy the freedom my expat friend experiences? These pressing questions need to be answered soon. However, I choose not to be steeped in such pessimism. One thing that has become clear is the accommodating nature of the Indians. From a time when an onscreen kiss was considered taboo, India has come a long way. The entertainment industry today has become a frontrunner in upholding woman’s rights, at least to some extent. With the advent of reality television the general public has become more accepting towards the image of a more Westernised Indian woman. We have welcomed talent from across globe in film and TV. Even an international adult movie star has been accepted as mainstream heroine. This of course cannot be considered a landmark change, but it indicates the change in the mindset of the modern Indian male.But to what extent the image of the bold Indian woman on celluloid proves helpful to the common Indian girl is open to debate…..Salloli Kumar is a regular on the page 3 circuit for nearly a decade…

While he makes it very clear that Bollywood is not on the cards at all, he just wishes the country could have offered more for his art.‘ICCR’s support to Aroha Choir led by Toshanbor is an attempt to diversify this support to the large number of artistes from Northeast and Meghalaya,’ said Dr. Suresh K Goel, Director General, ICCR.

If you find your teenage son indulging in alcohol or drugs, do not just blame his peers. A specific imbalance in the functioning of his brain may put him at risk-taking behaviour risk, a study has found.The study conducted on animals showed that the adolescent-specific behaviour may be driven by an imbalance in activity between the prefrontal cortex (PFC) – an area of the brain involved in cognitive control and inhibition – and the nucleus accumbens (NAC) which plays a central role in reward-seeking and addiction. Also Read – Add new books to your shelfResearchers from Dartmouth College in New Hampshire in the US said that the low activity in PFC with concurrent high activity in NAC – an imbalance which appears to exist only during adolescence – is essentially at odds with each other. This imbalance is behind the tendency that could lead to potentially dangerous behaviour, including drug use, harmful drinking, addiction, unsafe sex and risky driving, which may result in unintended injuries, violence and/or even premature death. “Understanding how specific changes in brain function during development relate to behaviour is critically important for determining why some individuals engage in excessive risk-taking behaviour during adolescence,” said David J Bucci, professor at Dartmouth College.“Our hope is that these findings will inform new means to minimise the potential for engaging in drug use and other harmful behaviours during this important period of development,” Bucci added in the paper published in the journal Current Biology.

Though initially doubtful about attending a literature festival in Dehradun, I was surprised by an unexpected number of literature enthusiasts crowding the event on its very first day. The second edition of ‘Valley of Words’ – a three-day extravaganza aiming to further the literary pursuit of Doon – got underway on November 23 and concluded on a Sunday afternoon at Hotel Madhuban, Dehradun.Amidst the scenic ambiance and hustle-bustle of the crowd, VoW was inaugurated by Governor of Uttrakhand Baby Rani Maurya, who also released the special first-day postal cover. Following the grand opening, Economist and Author Bibek Debroy gave a keynote on ‘Universal Learnings from Sanskrit Classics’. Also Read – Add new books to your shelfThe festival brought together best of writers, critics, painters, photographers, academicians, and other literarians to have compelling panel discussions across various fields. Among the 70 plus sessions, what caught my attention was the one on ‘India’s wars since Independence: (With a special tribute to Gen Zorawar Bakshi. Featuring notable names like Major General VK Singh, Major General Randhir Singh and Moderator Maj Gen Ian Cardozo, the session highlighted how Britishers identified the potential of Indian soldiers in fighting even the deadliest wars. But Indians in today’s time fail to acknowledge the contribution of their own soldiers. Cardozo concluded the session stating, “Events like Valley of Words give an opportunity to reminisce stories of the soldiers before and after Independence. Also Read – Over 2 hours screen time daily will make your kids impulsiveAnother highlight of day 1 was a session on ‘Women Extraordinaire by Dr Suchita Malik: A saga of the lives of five women of indomitable spirit, who refuse to crumble under pressure or give up because of the cruel twists of fate.’ Juggling between different halls of the hotel which hosted varied panel discussions, exhibitions, and book launches, I managed to get the final glimpse of this session where Malik talked about her book being the solid supporter of marriage – a crumbling institution. “This is the era of divorces, separation, and fights. Tolerance level has reduced to zero and we are not ready to rectify the problems, talk of compromises or adjustments in marriages. But I believe that marriage is an institution which gives us the anchor to society. You just need to give space to your partner and learn the art of tolerance. And as a writer, I believe that I have the creative freedom of highlighting different aspects of a situation/concept,” she stated. When asked about beautifully intertwining partition in the backdrop of the story, Malik drew parallel as to how Kaushalya’s story (lead protagonist) and India’s story (transformative stage of partition – pre-partition, partition and post-partition are synonymous with each other. “They grow up together, evolve together, face life together, struggle together and build up a new life,” she said. From theatre, journalism, music to politics and history – all of which influence literature directly or indirectly, gripping discussions around every possible field occupied other slots of the day. The evening got even more interesting when students from Graphic Era Hill University presented a Nukkad Natak that brought forth the pitiable condition of women in today’s society. First up for day 2 was a Hindi debate on ‘Bollywood ne Hindi ko Aabad/barbaad Kiya hai’, featuring Leela Dhar Jaagudi, Budhinath Mishra, Sangeet Gupta, and Kumudini Nautiyal. Rather than sticking to my chair, I decided to explore the exhibitions and craft expo presented by maestros as well as budding talent. ‘Gossamer Dreams’ by a 4 year old Ayan Gogoi Gohain, ‘A bird came down the walk: An ode to the birds in Mussoorie’, ‘Philately: Icy Continent and Indian Expedition’, ‘Images and Words: From a village in the valley’ and many more art shows were truly a feast for eyes. What stood out from the rest was ‘Glimpses of Last Shangri-La – The spirit of celebration’, an exhibition highlighting the aspects of the celebration of Indo-Tibetian Buddhism prevalent in the north-eastern Himalayan belt of India. The spiritual attainment in this ‘Land of the Lamas’ is evident through the use of enigmatic chantings, cosmic sounds of their traditional cymbals, wind instruments and drums. There is also a bountiful use of vibrant colours in their traditional attires which are used in their religious dance forms. The artist has attempted to represent these aspects in his artwork. Heading back, I took a seat to hear another panel discussion on Jairam Ramesh’s ‘Intertwined Lives’ which threw light on the life of PN Haksar. Jairam, who was in conversation with eminent journalist and author Sir Mark Tully, and Sekhar Raha elaborately talked on the relationship that Haksar shared with Indira Gandi. During the discussion, Jairam evidently mentioned Haksar’s voluntary exit from the sanctum sanctorum after he realised how things changed because of Sanjay Gandhi. Manish Tiwari in conversation with Manoj Jha, DP Tripathi, and Tarun Vijay were part of this edition’s Vox populi: ‘The best debate occurs outside the parliament’. Manoj Jha spoke of how people are unaware of the essence of ‘Debate’. “Debate is more about listening to other person’s point of view and countering it with a witty remark. The very essence of debate is wit, humour, addressing the point that your opponent makes and the ability to turn even the most intense conversation into an engaging dialogue.” Other sessions of the day including ‘Raga Bollywood by K L Pandey (where he introduced audience to the patterns of notes in a song), ‘Murder in Mahim’ (Author Jerry Pinto discussed his latest novel with RVS Kapur) were equally appreciated by the audience. Up next, on the stage was Vidya Sagar Group from Srinagar, singing folk songs of the valley to an enthusiastic audience. People couldn’t control but dance to their tunes until they ran out of breath. Soon after, ‘Cash and Russel show’ proved another treat for the music lovers who were enthralled by the duo’s (Vicky Cash and Sharon Russel) guitar showmanship. Organised in collaboration with REC (Rural Electrification Corporation) and Shivalik Hills Foundation, Valley of Words also offered a platform to young authors and poets to showcase their work. The third and final day had some of the best sessions of the festival but unfortunately wasn’t attended by many people. Speaking about ‘Literature in School’, the discussion among Syeda Imam, Matthew Raggett and Bijoya Swain was punctuated with interesting insights as they shared their views on ‘why today’s students lack interest in literature’. One of the panelists said, “This is the age of loneliness. Each member of the family is living in his own universe, unaware of the other person. But if we come out of our shell and start sharing our stories with others, we can in a way instill the love for literature within us as well as children. Because literature to me is ‘a sense of sharing’. We need to look beyond the books and experience life.” The next session titled ‘Yes Chief Minister’ was perhaps the most interesting of all. Prem Shankar Jha was in conversation with three biographers Dola Mitra, Khushwant Singh, and Shantanu Gupta, who have written about Mamta Banerjee, Amarinder Singh, and Yogi Adityanath respectively. The session started on a lighter note where the three of them talked about what struck them to write books on their respective subjects. But the panelist got into a heated argument after Jha questioned Shantanu Gupta about not maintaining neutrality in his book. The festival closed with acceptance speeches and valedictory address by Tarun Vijay.
Darjeeling: The Gorkha Janmukti Yuva Morcha will be taking up political programmes from June 10 to pressurise BJP to work towards the creation of Gorkhaland. It is on this poll plank that BJP and Hill allies had secured public mandate for both the Lok Sabha and Assembly bypolls in Darjeeling, stated the GJYM.”After June 10 we will launch a series of political programmes in the GTA area, Terai and the Dooars in the plains. We will start with postering. It will, however, not be like the violent agitations in the past. We will maintain cordial relations with the state government,” stated Amrit Yonzon, president, GJYM. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataThe agitation is also aimed at the parliamentary session that will commence from June 17. “Raju Bishta won the elections on the Gorkhaland poll plank. The allies and the BJP clearly stated in the Hills that people should vote for him, keeping ‘Jati and Mato’ (community and land) in mind. He got an overwhelming mandate so its time he and BJP live up to the commitment,” added Arun Chettri, general secretary. He further stated that during the 2017 agitation that had culminated in the 105-day-long bandh, Chief Minister Mamata Banerjee had clearly stated that it was their democratic right to launch an agitation as long as it was non-violent and peaceful. “However, only when the agitation turned violent did the state begin the crackdown. The 105-day-long bandh was not fruitful at all as it did not yield any result,” stated Chettri. Also Read – Lightning kills 8, injures 16 in stateHe stated that during the poll campaign in Darjeeling, Banerjee had publicly declared that she will work towards resolving the identity issue of the Gorkhas, along with political security. “The BJP has talked about a permanent political solution to the Gorkha impasse. They should spell out what it is,” Chettri added. When questioned on what their stand is regarding GNLF’s demand of 6th Schedule status to the Darjeeling Hills, spokesperson Anit Khati said: “6th Schedule has been rejected by the GJM led by Bimal Gurung in 2007, along with the entire Hills. Gurung had used the rejection of 6th Schedule issue to drive Subash Ghising and the GNLF from the Hills. They even had dubbed it as expired medicine. Now how can the same 6th Schedule be reintroduced? It is redundant. Nothing short of Gorkhaland will be accepted as a full and final political solution.”
So, with Kevin Garnett’s retirement seemingly inevitable. Let’s not remember Grandpa from the State Farm commercials. Let’s recall the young upstart who flipped the NBA on its head, and was one of the game’s most dominant players.Check out 18 year old KG at Farragut Academy in Chicago destroying everything in his path in 1995. Long live The Kid. Advertisement The saddest thing about watching a superstar fade away, is that images of their greatness are replaced with images of them barely hanging on. Kevin Garnett hasn’t averaged double figures since 2012. Last season, he returned to Minnesota to mostly mentor a roster full of potential superstars, but did little of note on the court.Yesterday, it was announced that Garnett was in the process of negotiating a contract buyout with the team. Most expect KG’s next move will be to announce his retirement.The irony of Garnett is that his perception among a younger generation of fans, furthered by State Farm commercials, is of a gruff old man. An elder statesman. It’s a disservice of perception, but all they know.To fans in their 30’s he will always be the pioneer of the NBA youth movement. The first modern player to go straight from high school to the NBA. A First Team All-NBA fixture for nearly a decade. A sure-fire first ballot Hall of Famer. “The Kid”.

In the most anticipated Summer League debut in the history, Lonzo Ball stunk up the Thomas & Mack Center with a horrendous 2 of 15 shooting night – including 1 of 11 from three – in a 96-93 overtime loss to the Clippers.Ball got off to a strong start by throwing a nice alley-oop to Brandon Ingram, but fell off a cliff as the game progressed. He finished with 5 points, 5 assists in 32 minutes. His shot looked bad.It’s hard to draw broad conclusions from one bad outing, but it certainly wasn’t the debut Magic Johnson was hoping for. Ball and the Lakers will take on the rival Celtics tonight in front of another sold out crowd.He’s got to play better than this.
