question:
Andy Murray lifted the Aegon Championships trophy for the fourth time on Sunday and then declared that he is playing even better than when he won Wimbledon two years ago. After winning two matches in one day, culminating with a 6-3, 6-4 breeze past Kevin Anderson in the final, he was asked to compare his current form to his historic triumph in 2013. He replied: 'I'm playing better than then.' With The Championships a week away, Murray is 11-4 second favourite behind Novak Djokovic. 'I feel like I have improved (since winning Wimbledon). Physically I'm definitely in a better place than I was then. Obviously I was having problems with my back around that time. Not so much on the grass but on the other surfaces.Andy Murray beat Kevin Anderson 6-3, 6-4 at the Aegon ChampionshipsMurray is 11-4 second favourite behind Novak Djokovic for WimbledonAsked to compare himself to his 2013 win: 'I'm playing better than then'Murray insists he is on better form than when he won at WimbledonWimbledon 2015: CLICK HERE for all the latest build-up and news

question:
(CNN) Last Friday, a million Russian schoolchildren watched a televised address from Russian President Vladimir Putin. "Artificial intelligence is the future, not only of Russia, but of all of mankind," Putin said. "Whoever becomes the leader in this sphere will become the ruler of the world." After seeing Putin's comments, SpaceX and Tesla CEO Elon Musk tweeted that "competition for AI superiority at national level (is the) most likely cause of WW3." Though never before stated so frankly by a head of state, Putin's views on AI are increasingly shared by national security leaders in the United States, China and around the world. As I wrote in a report published by the Harvard Belfer Center for Science and International Affairs, AI research is likely to deliver a revolution in military technology on par with the invention of aircraft and nuclear weapons. In other words, Musk is correct that each country is pursuing AI superiority and that this pursuit brings new risks.Gregory C. Allen: Though Russia may not lead in AI technology, it is at the forefront of weaponizing itAs an authoritarian leader of a nation with a declining economy, Putin has every reason to employ AI to maintain power, writes Allen 
 Question:Today, _'s military robots and drones are remotely operated, but in the future Russia plans to field "intelligent robotic complexes," meaning robotic military units powered by AI systems that can fight and kill without need for a human operator.
answer:
Russian


question:
The average curveball travels at 75mph (120km/h) in a smooth arc. While there's no sudden change in motion throughout its journey, this isn't what the batter sees as it nears the home plate. Instead, the ball creates an optical illusion that tricks the mind into thinking there is a 'break' in movement. And scientists say knowing this, could help the mind counteract the effect. Scientists at the University of Rochester say that our brains apply an algorithm, known as a Kalman filter, when tracking a baseball. In GPS devices, algorithms, including the Kalman filter, are used to estimate the location of your car based on its past position and speed.Our brains track moving objects using a similar algorithm to GPSThe algorithm estimates location based on its past position and speedWe do the same thing when perceiving position in our visual peripheryKnowing this can help us counteract the effect, the study claims 
 Question:This means you have a better chance of hitting a curveball by realising that our brains, like _, can lead us to 'see' changes in speed or direction that don't actually occur.
answer:

GPS
