The Bayern Munich goalkeeper talked how his team knows the rivals, ahead of their Champions League match.Bayern Munich will visit Anfield Road tomorrow to play against Liverpool in the UEFA Champions League Round of 16.And for Bayern’s goalkeeper Manuel Neuer, this is a very exciting match that he cannot wait to play on.“I’m looking forward to playing there. We heard a lot about the fans and atmosphere in the stadium,” he was quoted by The Liverpool Echo.“It will be two great games. For us, it’s very important to play Champions League.”“It’s a knockout game so it will be two finals. Everyone who watches a lot of football knows it’s a special atmosphere,” he commented.“Does it matter? Of course. I like it when fans are cheering a lot, close to the goal.”“But if you want to speak to your colleagues on the pitch it’s not that easy when it’s loud, they can’t hear you. You have to speak in a different way,” he explained.Crouch: Liverpool could beat Man United to Jadon Sancho Andrew Smyth – September 14, 2019 Peter Crouch wouldn’t be surprised to see Jadon Sancho end up at Liverpool one day instead of his long-term pursuers Manchester United.Bayern was struggling in the German Bundesliga for most of the first part of the season, but now they are just two points behind leaders Borussia Dortmund, Jurgen Klopp’s former team.“I think we know Klopp and we know his style. He knows Bayern Munich as well.”“No one is in a better position. We know him, he knows us,” he recalled.“I like his style. I’ve seen him at Rome, and I’ve seen him in the Brazil team, he’s doing a great job,” Neuer added about Liverpool’s goalkeeper Alisson Becker.Suited and booted.

News GRAMMYConnect Presents: 6 Degrees From Brandi Carlile 6 Degrees From Brandi Carlile With GRAMMYConnect grammyconnect-presents-6-degrees-brandi-carlile We put the seven-time GRAMMY nominee together with GRAMMYconnect.com for an IBM Watson-fueled exploration of the talented and powerful people who contributed to her careerthe GRAMMYsGRAMMYs Feb 5, 2019 – 11:36 am Over the course of their careers, GRAMMY-nominated artists intersect with hundreds—maybe thousands—of fellow musicians, producers, and other industry professionals. Many have a chance to work with entertainers outside the music industry, or even a politician or two.Given a typical GRAMMY-nominated artist’s far-reaching network, we thought it would be fun to explore a few of these connections with folk-rock singer/songwriter Brandi Carlile, who is nominated for six GRAMMYs this year. To help facilitate the conversation, we used GRAMMYconnect.com, our AI-powered site developed in partnership with IBM.”It was really cool to kinda stroll dowm memory lane and see so many of the people that have touched my live over the years,” says Carlile. “I even came across a few connections I didn’t know I had.”One of those hidden connections was with none other than Amy Schumer, the comedienne, actress, and activist who shares a passion for many of the same causes as Carlile. Turns out Schumer and Carlile were born on the same exact day: June 1, 1981. “I think it’s quite a compliment to share a birthday with somebody that exciting and funny, and of that depth,” says Carlile. The two actually met one time at a hotel swimming pool, when Brandi’s wife managed to get a laugh out of Schumer. “She made the funniest woman in America laugh.”Exclusive: Brandi Carlile On ‘By The Way, I Forgive You’ & “The Joke”That’s not the only surprising link GRAMMYConnect found to Carlile: The Washington-born singer also has deep ties to former President Barack Obama. Obama has included a few of Carlile’s songs on the favorites list he posts every year. Not only that, but he wrote the foreword to Cover Stories, Carlile’s 2017 album to benefit children of war.“I’ve got a lot of connection points with Barack Obama over the last eight to 10 years,” says Carlile. “There are so many ways he’s impacted my life… I think the most potent connection I have to him is that I proposed to my wife on the day that he came out as the first American president in support of marriage equality.”And here’s one that many of you probably missed: Brandi is connected to Bradley Cooper and Lady Gaga, due to her cameo in A Star is Born. In the scene, Cooper’s character, Jackson Maine, participates in a GRAMMY Awards tribute to Roy Orbison. Brandi plays herself, and takes the lead on vocals in the scene. We also explored Carlile’s connections to Dolly Parton, who will be honored as the 2019 MusicCares Person of the Year at the L.A. Convention Center two nights before the 61st Annual GRAMMY Awards. Click Dolly’s name to find out how the two are connected! And while you’re at it, find out how Carlile connects to GRAMMY winners Pearl Jam, Elton John, Kacey Musgraves and Maren Morris.To explore more of Brandi’s connections, or the connections of more than 19,000 GRAMMY-nominated artists through the years, go to GRAMMYconnect.com. Then, be sure to watch the 61st GRAMMY Awards on Sunday, Feb. 10 on CBS.Read more Facebook Twitter Email
A simulation of dark matter filaments across the universe. Zarija Lukic/Lawrence Berkeley National Laboratory Dark matter is an enigmatic beast. We can’t see it, yet we know it makes up most of our universe. Finding the mysterious particle (or particles) the exotic matter is composed of has puzzled and intrigued scientists for decades. On June 6 at the Planck 2019 conference, an international meeting highlighting frontier physics research, John Terning and Christopher Verhaaren, theoretical physicists at the University of California, Davis, presented a new theory for what makes up dark matter and how we might detect it. A preprint paper of their study was uploaded to the arXiv directory on May 31. Dark matter and dark energy, two theoretical forms of matter, are thought to make up more than 85% of the known universe. When we look out into space, the evidence for the existence of dark matter is plentiful — we can see the effect it has on gravity and the expansion of the universe. We know something, an invisible particle perhaps, is lurking out of sight and responsible for the way our universe works. Scientists have long struggled to find the elusive, exotic particle that makes up dark matter, and more theories abound every year. In December, an Oxford scientist proposed that the universe was made up of a dark fluid. Others have suggested hunting for dark matter in cutting-edge new ways. Still, we have failed to detect it.Which brings us to Terning and Verhaaren’s idea. They argue for a new “type” of dark matter and a way to detect it, a one-two punch of theory and experimental validation. However, the authors of the study caution that verifying it could take quite some time. The new type of dark matter is different from previous theories, which suggest the exotic, invisible particles may be made up of weakling interacting massive particles, or WIMPs. No experiments have been able to find these particles, though scientists have built large, shielded laboratories that hope to reveal them. “We still don’t know what dark matter is,” said Terning in a press release. “The primary candidate for a long time was the WIMP, but it looks like that’s almost completely ruled out.” The private rocket company trying to send Australia to… See SLAC, a two-mile particle accelerator next to Stanford 2 3:17 Share your voice Comments The researchers looked at an opposing theory for dark matter with an equally fantastical name: “dark electromagnetism.” It says there’s a subatomic particle known as a dark photon which sometimes interacts with regular photons that we can already detect. The duo added their own spin to the idea by showing dark matter might be caused by “dark monopoles,” which are based on quantum theory.It all gets very tangled here, especially for us mere mortals struggling with everyday physics. The bottom line? We’ve got a new theory which proposes the “dark monopole” could be detected in an experiment thanks to its interactions with regular photons and the Aharonov-Bohm effect, which has been proven experimentally. However, the observable effect would be incredibly small — even smaller than gravitational waves — and we don’t yet have the technology to detect such minute signals right now. Alan Duffy, a dark matter researcher at Swinburne University in Australia, notes how the first detection of gravitational waves (itself only a theory until recently) took “a century of heroic scientific and engineering effort” suggesting that might be “a worry for the testability of the [new] prediction.”Where does that leave Terning and Verhaaren’s theory? Well, as a theory, of course. But that’s where all good science starts. Tags 33 Photos Now playing: Watch this: Sci-Tech
Finance Minister Arun Jaitley welcomed the interest rate cut by the Reserve Bank of India (RBI), terming the move as “very positive for the economy.”The RBI cut its repo rate by 25 basis points, to 7.75%, for the first time in almost a year, on the back of easing inflation and weak demand.Repo rate is the rate at which banks borrow from the RBI. A reduction in the rate makes funds cheaper and helps retail and institutional borrowers reduce their interest outgo, a key factor in deciding to fund projects or investments through a bank loan.”Reduction in the rates is a positive development. It will lead to more money in the hand of the consumers and result in greater spending. It’s positive for the Indian economy,” Jaitley told reporters on Thursday, according to Business Line.He expressed hope that the move will assist in reviving the investment cycle that the government seeks to restore.Meanwhile, Subramanian noted that the move would provide some fillip to the economy, directly and indirectly.”It does signal a shift in the underlying (monetary) stance going forward,” said said Arvind Subramanian, Chief Economic Adviser to the Finance Ministry in an interview with television channel CNBC-TV18.

Explore further For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson’s team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative. To rephase the spectral components, the sound waves were sent through an asymmetric loop filter on a waveguide of PVC pipe, about 8 m long. The 0.65-meter loop split the sound waves into two unequal path lengths, resulting in destructive interference and standing wave resonances that together created transmission dips at regular frequencies. Due to anomalous dispersion (which changes the wave speed), sound pulses traveling through the loop filter arrived at the exit sooner than pulses traveling straight through the PVC. With this experiment, the group velocity could actually reach an infinitely small amount of time, although the individual spectral components still travel at the speed of sound. “We also achieved what is known as a ‘negative group velocity,’ a situation in which the peak of the output pulse exits the filter before the peak of the input pulse has reached the beginning of the filter,” explained Robertson. “Using the definition for speed as being equal to distance divided by time, we measured a negative time and thus realized a negative velocity.”It might not seem that a negative velocity would exceed the speed of light, but in this case, Robertson said, the speed of the pulse is actually much faster than c. “Consider the pulse speed in a slightly less dramatic case,” Robertson said. “Say the peak of the output pulse exits the filter at exactly the same time as the input pulse reaches the beginning. In this less dramatic case, the transit time is zero and the speed (distance divided by zero) is infinite. So we were beyond infinite! (‘To infinity and beyond,’ to steal a line from Toy Story.) In our experiment, we measured a negative transit time corresponding to a negative group velocity of -52 m/s.”Although such results may at first appear to violate special relativity (Einstein’s law that no material object can exceed the speed of light), the actual significance of these experiments is a little different. These types of superluminal phenomena, Robertson et al. explain, violate neither causality nor special relativity, nor do they enable information to travel faster than c. In fact, theoretical work had predicted that the superluminal speed of the group velocity of sound waves should exist.“The key to understanding this seeming paradox is that no wave energy exceeded the speed of light,” said Robertson. “Because we were passing the pulse through a filter, the sped-up pulse was much smaller (by more than a factor of 10) than the input pulse. Essentially, the pulse that made it through the filter was an exact (but smaller) replica of the input pulse. This replica is carved from the leading edge of the input pulse. At all times, the net energy of the wave crossing the filter region was equal to, or less than, the energy that would have arrived if the input pulse had been traveling in a straight pipe instead of through the filter.”Is this phenomenon simply the result of a clever set-up, or can it actually occur in the real world? According to the scientists, the interference that occurs in the loop filter is directly analogous to the “comb filtering” effect in architectural acoustics, where sound interference occurs between sound directly from a source and that reflected by a hard surface.“The superluminal acoustic effect we have described is likely a ubiquitous but imperceptible phenomenon in the everyday world,” the scientists conclude.Citation: Robertson, W., Pappafotis, J., Flannigan, P., Cathey, J., Cathey, B., and Klaus, C. “Sound beyond the speed of light: Measurement of negative group velocity in an acoustic loop filter.” Applied Physics Letters 90, 014102 (2007).By Lisa Zyga, Copyright 2006 PhysOrg.com.

In the latter case, the peak of the output pulse traveling through the loop filter exited the filter before the peak of the input pulse had reached the beginning of the filter. Image credit: Bill Robertson, et al. Past experiments have demonstrated that the group velocities of other materials’ components—such as optical, microwave, and electrical pulses—can exceed the speed of light. But while the individual spectral components of these pulses have velocities very close to c, the components of sound waves are almost six orders of magnitude slower than light (compare 340 m/s to 300,000,000 m/s).“All of the interest in fast (and slow) wave velocity for all types of waves (optical, electrical, and acoustic) was initially to gain a fundamental understanding of the characteristics of wave propagation,” Robertson told PhysOrg.com. “Phase manipulation can change the phase relationship between these materials’ components. Using sound to create a group velocity that exceeds the speed of light is significant here because it dramatically illustrates this point, due to the large difference between the speeds of sound and light.”The experiment was conducted by two undergrads, an area high school teacher and two high school students, who received funding by an NSF STEP (Science, technology, engineering, math Talent Enhancement Program) grant. The grant aims to increase recruitment and retention of students to these subjects.In their experiment, the researchers achieved superluminal sound velocity by rephasing the spectral components of the sound pulses, which later recombine to form an identical-looking part of the pulse much further along within the pulse. So it’s not the actual sound waves that exceed c, but the waves’ “group velocity,” or the “length of the sample divided by the time taken for the peak of a pulse to traverse the sample.” “The sound-faster-than-light result will not be a surprise to the folks who work closely in this area because they recognize that the group velocity (the velocity that the peak of a pulse moves) is not merely connected to the velocity of all of the frequencies that superpose to create that pulse,” explained Robertson, “but rather to the manner in which a material or a filter changes the phase relationship between these components. By appropriate phase manipulation (rephasing) the group velocity can be increased or decreased.”
