French Open 2019: Rafael Nadal tops Roger Federer in straight sets to reach final

first_imgRafael Nadal made quick work of Roger Federer in their first French Open meeting since 2011, beating his rival 6-3, 6-4, 6-2 Friday in strong wind to reach his 12th final at Roland Garros.Nadal has never lost a semifinal at the clay-court Grand Slam tournament. Never lost a final, either.And he’s never lost to Federer in Paris, improving to 6-0. Overall, Nadal leads their series 24-15. Federer had won their past five meetings, but those were all on hard courts.It’s a whole different task to take on Nadal on clay, in general, and at the French Open, in particular, where his one victory away from a 12th championship, which would be more than any man or woman has won at any of the Grand Slam tournaments.In Sunday’s final, the No. 2-seeded Nadal will take on either No. 1 Novak Djokovic or No. 4 Dominic Thiem.This was the first time since 2011 the four top-seeded men were in the semifinals at Roland Garros.Like so many times before, it was Nadal’s topspin-heavy lefty forehand, his relentless ball-chasing and his return game that gave Federer fits.Frustrated the guy so much that the generally stoic Federer smacked a tennis ball toward the stands after getting broken to trail 2-1 in the third set.It would soon be over.Federer, who was playing at Roland Garros for the first time since 2015, hadn’t lost a set through five victories over the past two weeks. With an aggressive, head-to-the-net style, he had been broken a total of only four times by those opponents.advertisementNadal easily exceeded that in a span of three sets across less than 2½ hours, winning 6 of 13 return games.The 37-year-old Federer, whose 20 Grand Slam titles are a record for a man, was serenaded off the court by spectators’ chants of his first name. He raised his right arm for a quick wave as he walked away perhaps for the final time. He missed the tournament in 2016 with a bad back, then skipped it the next two years to prepare for grass and hard courts.He looked quite good in his return, until running into his old nemesis.Also Read | French Open 2019: Teenager Vondrousova beats Konta to reach finalAlso Read | French Open 2019: Noavk Djokovic sets semi-final clash with Dominic ThiemAlso Seelast_img read more

Why a drop of oil bounces in a waterethanol gradient and eventually

center_img In physics, the Marangoni effect describes differences in surface tension between liquids that can lead to seemingly strange behaviors such as “tears” forming in a glass of wine with a lot of alcohol in it. In this new effort, the researchers explored the Marangoni effect as it applies to the bouncing of oil drops in a jar containing a water/ethanol gradient.To set up the experiment, the researchers carefully poured ethanol into a jar of water, avoiding too much mixing, such that a density gradient formed naturally. Then, they introduced a single drop of oil, in this case, anethole, into the container. The drop sunk slowly through the mixture before rapidly rebounding straight back up. The drop does this several times before eventually sinking all the way to the bottom of the container. After careful study of the whole scenario, the researchers discovered what was actually happening.At the onset, the drop falls due to gravity—the researchers found that as it does so, the surface tension on the drop is different on the top and bottom (the Marangoni effect), resulting in an energy buildup. Once it reaches a tipping point, the energy is released, pushing the drop back up toward the surface. But each time it falls and rebounds, the amount of stress that builds up lessens, likely due to the mixing of the water and ethanol as the drop moves down and up repeatedly. Eventually, the amount of energy released is not sufficient to propel the drop upward, and it falls to the bottom of the container. The researchers note that the same scenario can be replicated using other types of oil and liquid density gradients. More information: Yanshen Li et al.
