Commentary Scott Torgersons death tweet about Desmond Howard no joke

When I was a kid, I hated the Pittsburgh Steelers. I still do to a certain extent. They always seem to beat the Cincinnati Bengals and the Cleveland Browns, sometimes in the most heartbreaking ways imaginable. I remember when Steelers quarterback Ben Roethlisberger came very close to losing his own life in June of 2006 when he was involved in an ugly motorcycle accident. Luckily, Roethlisberger survived the crash, but I was not about to send my condolences to the quarterback of the Steelers. I was mad that he didn’t die that day. I thought with Roethlisberger out of the picture, maybe the Bengals and the Browns could finally break through and win a championship. I realize now that comments such as those are insensitive. Wishing death upon someone is cold and heartless. I could use the “excuse” that I was young and didn’t know any better, but, nevertheless, I accept the fact that I used a very poor choice of words. Apparently, I’m not the only one who wishes death to well-known athletes. Last weekend, Scott Torgerson, host of the popular sports talk radio show “Common Man and the Torg” here in Columbus, made a similar comment.  Torgerson, who professes his Buckeye fandom on a daily basis, along with his extreme distaste for everything involving the Michigan Wolverines, tweeted this about former Heisman trophy winner and current ESPN college football analyst Desmond Howard: “I wish Desmond Howard would get fired or die so I can watch Gameday again.” Now, I know that Ohioans, fans of the Scarlet and Gray, are bred to hate that School up North. Lord knows that image of Howard striking the Heisman pose against the Buckeyes makes any Ohio State fan cringe.  However, there is a fine line between being passionate and letting that passion overtake you. That is what happened to Torgerson. He deleted the tweet and apologized for his comment, tweeting, “My Desmond Howard tweet was a joke. I think if you listen to the show you know that. My apologies to those who took it seriously. Total Joke.” My question to Torgerson is this: How is wishing someone would die a joke? I recently went to the funeral of the brother of one of my best friends from high school. Believe me, death is no laughing matter. Since this infamous tweet, Torgerson has been suspended from the airwaves indefinitely.  The lesson to take from this is do not let your fandom cloud your overall judgment as a human being.  There is more to life than spending every waking moment hating someone just because they beat your favorite team. I learned this lesson when I was young. Unfortunately, there are some people in this world like Torgerson who didn’t get the message until it was too late. Think before you say it. Think before you tweet it. Think before it is too late to fix. read more

Urban Meyer BCS a flawed system

OSU coach Urban Meyer talks on the sidelines during a game against Illinois Nov. 16 at Memorial Stadium. OSU won, 60-35. Credit: Ritika Shah / Asst. photo editorOhio State football coach Urban Meyer is not ready to talk about his team’s national championship chances.Meyer sidestepped yet another question about what the rest of the country thinks about his team, and if the fact that the last two times OSU (10-0, 6-0) played for the national championship (2007, 2008) has crossed his mind. Instead, he elected to talk about how running backs redshirt-freshman Warren Ball and freshman Ezekiel Elliott need to get better at tackling to help the punt team.“Ezekiel on our punt team, I have to teach him how to tackle. Warren Ball is running down on kickoff,” Meyer said, to chuckles from the media. “He hasn’t done that in his high school career. We’re going to work hard on that in practice. Any other questions about Warren Ball’s coverage?”One thing Meyer did comment on was the Bowl Championship Series, which is in its final year of selecting the two teams who play for the national title.“Without spending much time on it, because it’s not fair for our team to do that, I will say this: I think it’s a flawed system,” Meyer said. “When you logically think about it, what the BCS people have done, which obviously we’re all part of it, I think it was great for a while.”The Buckeyes are ranked No. 3 in the BCS for the second week in row, but sits a mere .0013 points ahead of No. 4 Baylor after beating Illinois 60-35 in Champaign, Ill. A college football playoff will be implemented next season, with a selection committee choosing four of the nation’s top teams to play in a round of semifinals before the winners meet in the national title game.“I think (the BCS) took an imperfect system and did the best you can without a playoff,” Meyer said. “There’s going to be controversy in playoffs, too…There’s not a 64-team playoff. You’re going to have four guys. What is that fifth team going to feel like?”Baylor defeated Texas Tech, 63-34, Saturday, which catapulted them ahead of OSU in the AP rankings. Although the Buckeyes defeated Illinois by nearly the same margin, the Illini made things interesting in the fourth quarter, cutting the lead to 12 with just under nine minutes to go.Meyer was not pleased with his coaching performance in the win, giving himself a “C.”“I was worried about too many other things,” Meyer said. “I can promise you, we’re going to coach better this week.”Meyer and the Buckeyes are set to take on Indiana (4-6, 2-4) in the final home game of the season Saturday. Kickoff is scheduled for 3:30 p.m. at Ohio Stadium. read more

Mens Basketball Ohio States interior strength paying dividends for team success early

Forward Jae’Sean Tate attempts a lay-up in the Buckeyes’ 80-55 win over Northeastern on Sunday. Credit: Jacob Myers | Managing Editor for ContentOhio State’s lineup has held a size advantage over every opponent played through its first three games.But against Northeastern, the Buckeyes found themselves in an unfamiliar position. They were the shorter team. Position-by-position, there was not a single Buckeye-starter taller than the Huskie-starters, and only at one position was the size equal.It didn’t seem to matter, though. For its fourth-straight game, Ohio State dominated the interior, out-rebounding Northeastern 38-29 and vastly out-producing the Huskies in the paint, holding an advantage of 48-26 in points in the paint. Northeastern head coach Bill Coen said while his team held the advantage in height over the Buckeyes, it was the girth and tenacity of the Buckeyes that proved the difference-maker.“They got some wide-bodies and they can carve out space in and around the basket and it’s hard to move them out once they gain position,” Coen said after the game. “You look at a guy like Charles Barkley, he’s not 7-foot, but he could rebound because he’s got a low center of gravity and he can wedge in there and create space for himself. They’ve got some tough body types, the matchup too. I think really good physical strength and they were able to hold their position and game position.”The weight advantage did not extend to every player the Buckeyes had, however. Center Micah Potter and guards Musa Jallow and C.J. Jackson did not hold a size advantage over their counterparts.However, Ohio State’s top-rebounders, forwards Jae’Sean Tate and Keita Bates-Diop, both came in with significant weight advantages over their opposite numbers. As a result, both players proved to be explosive threats for the Buckeyes in the post. The two were the game’s leading scorers with 24 and 19 points, respectively. The domination in the paint began right out of the gate from Tate, who bullied his way through defenders in the game’s opening minutes. He opened the game up with a layup after he saw no one open to pass to and followed that up shortly after with a short-range jumper. About five minutes into the game, Tate had 11 points — all coming from plays in the post.Bates-Diop also put together a dominating performance inside. Of his 19 points, eight came from a pair of layups, a short-range jumper and a dunk with one free-throw coming off an and-1 on a layup and two other free-throws coming from fouls inside the paint.Tate said strong play inside has become a mantra for he and Bates-Diop this season, but also said his teammates interior play has assisted the two forwards.“Me and Keita were very effective [inside],” Tate said. “Some people call a matchup problem and just out teammates, the point guard, C.J. [Jackson] being aware of the mismatch in the situations, he’s doing a great job of that.”Ohio State has been no stranger to dominating inside this season. Before this game, Ohio State held a 138-66 advantage in paint points and had out-rebounded opponents 135-85. Of Ohio State’s 259 points total, 53.3 percent of them came from inside.Part of the reason Ohio State has been so productive in the paint has been its ability to recover offensive rebounds. The Buckeyes are tied for 38th in the country with an average of 15 offensive rebounds per game.Head coach Chris Holtmann said his team last year at Butler was a strong defensive rebounding team, but it was one of the worst at collecting rebounds off the offensive glass. The now-Ohio State head coach said he thinks this team has a chance to be an all-around great team at gather rebounds.“We have a chance to be a pretty good rebounding team,” Holtmann said. “We better be good defensive rebounding. We were a good defensive rebounding at Butler as well, but I think we have the potential to be good on both ends if we pursue the ball like we need to. Because we have some guys that have a natural nose for the ball.”With several other big men like forwards Kaleb Wesson and Kyle Young at 6-foot-9, 270 pounds and 6-foot-8, 205 pounds, respectively, Ohio State has plenty of size to continue to beat up on most teams throughout the season and dominate in the paint and on the glass.The Buckeyes might not be able to do that in their next matchup, however. They are going to be traveling to Portland, Oregon, to take on Gonzaga, a team Holtmann said was big last season and has continued to dominate its opponents with size this season.Going up against one of the first teams that will truly have Ohio State beat in size in both height and girth, Ohio State could be faced with its first real challenge this season.“Well I think we’re going to learn a lot about kind of our tenacity when it comes to pursuing the ball in those situations,” Holtmann said. “They’re always kind of one of the biggest teams both in size and in physicality in the country. Last year they were massive. This year, they’re big as well and they’re really organized and they’re older. They don’t beat themselves.“I think as much as anything, it’s going to test us in a lot of ways, but it’s going to test our pursuit of the ball and our tenacity and how tough-minded we are.” read more

Medina – September 14, 2019 Kenyan international, Victor Wanyama, was the protagonist of a summer transfer saga, but in the end, he is set to stay at Tottenham Hotspur.“In midfield, maybe Harry Winks. He played really well for Spurs against Barcelona in the Champions League, against a similar type of players. Again, it won’t be easy, but I think in Seville on Monday night, we are going to have to do as well as we can to keep the ball against Spain. Winks is as good as anyone who can come in for Jordan Henderson in terms of technical ability,” Carragher said to Sky Sports.Winks has an impressive form for Spurs this season and put in a decent display in the team’s UEFA Champions League loss to Barcelona at Wembley earlier this month and carried that form during the victory against Cardiff City.The 22-year-old was a standout performer for Mauricio Pochettino’s side against the La Liga champions star-studded midfield and his club manager has previously likened him to one Barcelona’s greatest player Andres Iniesta because of his ability to dictate play.last_img read more

Petit says Arsenal is wasting opportunities

first_imgFor the former Gunners midfielder, the English Premier League team is wasting its opportunities by not signing anybody during the transfer window.Arsenal has not spent a dime during the January transfer window in the English Premier League.But the team might need a player or two, as they are currently in the sixth position of the table with 47 points 15 points behind leaders Liverpool.For former Gunners midfielder Emmanuel Petit, Arsenal not getting any new footballers during the January transfer market window is a wasted opportunity.“The frustration level must be very high for Emery, as in only his second transfer window as Arsenal manager he was told he cannot sign anybody,” Petit was quoted by Sky Sports.“You look at the money Manchester United, Liverpool, and Manchester City spend and unless you join them and put the cash on the table to compete for the best players, you are going nowhere.”Not the end to the weekend we were all hoping for 😔But, there’s still another 13 @PremierLeague games to go – let’s dust ourselves down, regroup and we’ll go again at Huddersfield 👊#WeAreTheArsenal 🔴 pic.twitter.com/gTSzRMuDks— Arsenal FC (@Arsenal) February 3, 2019Harry Maguire, Manchester UnitedLiverpool legend Nicol slams Harry Maguire’s Man United form Andrew Smyth – September 14, 2019 Steve Nicol believes Harry Maguire has made some “horrendous mistakes” recently, and has failed to find his best form since joining Manchester United.“Tottenham are not spending money but they are in the position Arsenal were in a few years ago, building a stadium, but there is no excuse for Arsenal now,” he complained.“If you sack Arsene Wenger and then say to the guy who replaces him ‘you have no money to spend on new players’, I would ask; what was the point of sacking Wenger in the first place?”“Defensively, Arsenal have not been good enough this season, so I was surprised they did not try to sign defenders in January. But the problems they have will not be solved by signing a player or two,” he continued.“Clearly, the defense is a problem.

Feynman wasnt joking Modeling quantum dynamics with ground state wavefunctions

first_img © 2013 Phys.org. All rights reserved. This allowed the researchers to specify a direct analogy to the convergence seen in ground state systems – that is, the rate of expansion convergence is inversely proportional to two-body interaction strength. “As far as we know,” McClean says, “nobody has used configuration interaction to do a time-dependent problem in the way we did in our paper.” Researcher Jarrod R. McClean discussed with Phys.org the research that he and his colleagues, Profs. John A. Parkhill and Alán Aspuru-Guzik, conducted. “In solving quantum dynamical problems prior to our findings, the large dimension and complexity of models in quantum mechanics make it very computationally expensive to perform dynamics simulations,” McClean tells Phys.org. “This means that only very short time scales can be examined with high accuracy. Moreover,” he points out, “previous attempts to utilize modern parallel computers have been hindered by strong spatial interactions within quantum systems.””One usually thinks of quantum information as a field that leads to the development of quantum computers,” Harvard’s Aspuru-Guzik notes. “It turns out that classical computing can benefit and learn from the ideas of quantum information. This application of Feynman’s clock to the challenging problem of time evolution is an example of this.”Traditional algorithms utilize parallelization in space, in which a supercomputer comprising many processors spatially distributes and advances the problem in single temporal increments. “What is less natural,” McClean continues, “is to think about the possibility of setting up a calculation that is parallel in time.” This means that the simulation at different points in time has to be simultaneously calculated on many processors. “That’s the focal point of our study,” McClean stresses. “We exploit the clock construction, which was originally designed to think about quantum computing for use in parallel computers.”McClean notes the importance of demonstrating their proposal’s accuracy convergence by applying the configuration interaction method – a linear variational method for solving the nonrelativistic Schrödinger equation. “We wanted to show that the convergence of configuration interaction in spacetime has similar properties to its usual application in ground state chemistry,” he explains. “To do this, we had to find a system of interest where we could also control the importance of two-body and one-body interactions.” (Phys.org) —Amongst the late Richard Feynman’s many prolific and profound contributions to quantum mechanics, the eponymous Feynman clock is perhaps one of the more innovative. Conceived as a solution to the problem of quantum simulation, the Feynman clock proposes using quantum computers to simulate quantum systems – and in so doing, conjectures that if a quantum system moves stepwise forward and then backward in time in equal increments, it would necessarily return to its original state. While originally a linear concept, scientists at Harvard University and the University of Notre Dame recently generalized the proposition to construct a more flexible discrete-time variational principle that leads to a parallel-in-time algorithm. (A variational principle is a scientific principle, used within the calculus of variations, which develops general methods for finding functions which minimize or maximize the value of quantities that depend upon those functions.) The researchers then used that algorithm to describe time-based quantum system evolution as a ground state eigenvalue problem – that is, the quantum system’s lowest energy state – which led them to realize that the solution of the quantum dynamics problem could also be obtained by applying the traditional ground state variational principle. More information: Feynman’s clock, a new variational principle, and parallel-in-time quantum dynamics, PNAS Published online before print September 23, 2013, doi:10.1073/pnas.1308069110 Citation: Feynman wasn’t joking: Modeling quantum dynamics with ground state wavefunctions (2013, October 18) retrieved 18 August 2019 from https://phys.org/news/2013-10-feynman-wasnt-quantum-dynamics-ground.html Explore further Researchers propose a new system for quantum simulation Journal information: Proceedings of the National Academy of Sciences To take advantage of parallel processing in time, McClean notes, the scientists also needed to demonstrate that their construction had a natural division into smaller time segments that could be handled independently by different processors on a parallel computer. “The challenge, of course, was to show that this was computationally advantageous in comparison to traditional approaches of stepping forward in time,” he adds.To address these challenges, McClean says that the key insight at the heart of their work was that tools developed in quantum computation may be exportable to classical simulations of quantum systems. “Through this,” he explains, “we recognized that by turning quantum dynamics problems into ground state problems, we could leverage tools from ground state simulation to address difficulties in both the dimension of the space and the length of simulation time required.” In addition, he points out that the key to achieving speedup in parallel-in-time algorithms is the ability to precondition, or develop an inexpensive guess for, the solution in serial mode before refining it in parallel mode. One of the paper’s key findings was that the new construction performs favorably against existing algorithms. “We demonstrated that for a representative quantum system, when the same dynamics and partitioning is performed, our algorithm would finish in less human time than the competing algorithms by making use of parallel computer architectures,” McClean says. “We ensured that all factors in our comparison were as equal as possible, converging to the same level of accuracy and averaging the speedup results over different time partitions.”McClean acknowledges the possibility of constructing similar algorithms from the other time-dependent variational principles. “However,” he points out, “one must be careful when selecting spacetime basis functions. These methods are in their infancy, and it’s a current research topic to develop them for use with the Schrodinger equation and quantum mechanics.”In a similar vein, McClean states that there are other methods that use extended spacetime to remove time-dependence from a problem. “However,” he clarifies, “these methods use the time-independent Hamiltonian in a way that is similar to traditional time-stepping, retaining many of the drawbacks. In our approach, we take a time-independent construction whose ground state directly encodes the dynamics, allowing us to use any number of previously developed techniques for determining the ground state.”In addition, the metrics inspired by their approach can be used to quantitatively understand the errors resulting from truncating the Hilbert space of many-body quantum dynamics. “In order to make quantum simulations tractable,” McClean explains, “it’s almost always necessary to hypothesize that a small part of the quantum space is relevant and simulate exclusively in that space. Our metrics allow researchers to quantitatively assess if the selected space includes all the interesting quantum dynamics – and if not, at exactly what time the violation occurs, thereby making it unnecessary to throw out their entire simulation.” For example, to simulate the dynamics of charge transfer in a protein, it would be necessary to pick a subset of quantum states and model the dynamics within them. “Our error metrics could allow someone to quickly discover if they had selected the wrong states, and reselect them before too much computational power had been wasted.”In other cases, he continues, the necessary states for simulation might be known, but the total time of simulation needed to see a rare event of interest might be too long for a single processor run in serial . “In that case, our technique could be used in conjunction with spatial parallelization to parallelize over time and reduce the human time required to see that rare event. This leads to faster results and more rapid development of continuing experiments.”Moving forward, McClean believes that there are many untapped resources in the field of quantum information which have the potential to advance classical simulation techniques. “Methods developed for adiabatic quantum computation may be directly applicable to our method to further refine its speed and accuracy. In terms of the planned next steps in their research, he adds that they are looking at applying more advanced techniques from electronic structure to the ground state formulation of dynamics. “Hopefully,” he adds, “the methods that have been successful in describing these problems can yield new insights into dynamics problems for quantum chemistry.”McClean notes that there are other areas of research that might benefit from their study. “Our method should be generally applicable across many computational domains that study the time dynamics of physical systems,” he tells Phys.org. “While many schemes currently exploit spatial parallelism to take advantage of modern supercomputers, temporal parallelism has been a relatively untapped resource to date. Our method and variations of it,” McClean concludes, “will likely be very useful in tapping this additional resource to scale physical simulations to previously unreachable timescales.” The spin triangle within the vanadium compound, used as a model system for the TEDVP.
