MONZA, Italy -- Sebastian Vettel labelled Monzas contract renewal fantastic news after it was confirmed the iconic venue will remain Italin Grand Prix host until at least 2019.Monzas future has been the subject of much speculation this year, with lengthy negotiations between Bernie Ecclestone and the Automobile Club dItalia. Imola had previously been mooted as a replacement for the Italian Grand Prix but Vettel, set for his second one as a Ferrari driver this weekend, thinks there is no other place which can host the race.Told about the renewal after FP2, Vettel said: Thats fantastic news. I think we all love this track. Obviously Ive raced in red and Ive raced in different colours, its the best to race in red obviously. But ignoring that for a second its a fantastic track, its a fantastic atmosphere.Vettel thinks Monza should remain on the race track even if it means the commercial rights holder fails to match the fees paid by others.We need this track on the calendar and therefore thats excellent news, even if I dont know how much tracks are paying these days but we should even race here if -- now Im going to get myself in trouble -- but even with a bad deal for whoever is cashing in, Monza has to stay on the calendar because it means more than just cash. It means history, tradition, racing, enthusiasm, Ferrari, so theres a lot of reasons why we should come here.Vettels enthusiasm for the new deal was echoed by reigning world champion Lewis Hamilton, who believes F1 would not be the same without Monza, which has been on the calendar for every season bar one (1980) since the inaugural world championship in 1950.Im so happy., Hamilton said about the new deal We cant ever lose this track; to see the fans here and the track is phenomenal, so unique. This is part of the heritage of the sport, and if you lose this grand prix you lose a very big part of what F1 is. http://www.saintsrookiestore.com/Saints-Sam-Mills-Jersey/ . Philadelphia is 2-0 against the Senators this season and scored five goals in each victory. The Flyers recorded a 5-0 win in Ottawa on Nov. 12 and then earned a 5-2 home decision on Nov. 19. The Flyers have claimed three straight and four of the last five encounters with the Sens overall and Philly has won two in a row and three of its past four tests in Canadas capital city. http://www.saintsrookiestore.com/Saints-Michael-Thomas-Jersey/ .

Conventional swing, reverse swing, contrast swing. In the past few years cricketers have been barraged with new and convoluted descriptions of a balls deviation through the air, but only the select few can differentiate between each, let alone unravel the science behind them. One such man is Rabindra Mehta, a NASA scientist and former club fast bowler based in California, who has studied cricket-ball aerodynamics for nearly three decades. Here, in response to an article published at Cricinfo last week, he gives the definitive answer to the mysteries of swing.Does it really matter what you call a particular type of swing? Well, it matters because the science dictates what type of swing it is. Of course, bowlers do not have to know or understand the science, but Im sure they would appreciate knowing when a certain type of swing will be effective and in which direction the ball is likely to swing.Having studied cricket ball aerodynamics for over 25 years, my mission here is to reveal the answers to all the mysteries surrounding swing bowling, and hopefully, to quash once and for all, all the myths and erroneous explanations that are still floating around the cricketing world. To assure you that these three types of swing do actually exist, and are regularly practised on the cricket ground, I have quoted examples from the famous 2005 Ashes series between England and Australia.Let us first look at some of the fundamental flow physics that will help to explain all three types of cricket ball swing. As the ball is flying through the air, a thin layer of air called the boundary layer forms along the balls surface. The boundary layer cannot stay attached to the balls surface all the way around the ball and it tends to leave or separate from the surface at some point. The location of this separation point determines the pressure, and a relatively late separation results in lower pressure on that side. A side force or swing will only be generated if there is a pressure difference between the two sides of the ball.Now the boundary layer can have two states: a smooth and steady laminar state, or a time-varying and chaotic turbulent state. The transition from a laminar to a turbulent state occurs at a critical speed that is determined by the surface roughness; the rougher the surface the lower the critical speed. However, on a very smooth surface and at nominal speeds, a laminar boundary layer can be forced to turn turbulent by tripping it with a disturbance. The disturbance can be in the form of a local protuberance or surface roughness which adds turbulent eddies to the laminar layer and forces it to become turbulent. It is similar to putting your finger into a smooth stream of water from a tap: note how small chaotic turbulent motions are generated downstream of the finger location. Now it turns out that a turbulent boundary layer (because of its increased activity and energy) can stay attached to the balls surface for a longer distance compared to a laminar layer.Conventional SwingIt is said that this type of swing originated around the turn of the century, but there is evidence that it was in existence well before that time. Bowlers from that era, including WG Grace, had realised that a perfectly new ball favoured the peculiar flight, so there is not much doubt that it was conventional swing that these bowlers were referring to.Fast bowlers in cricket make the ball swing by judicious use of the primary seam. The ball is released with the seam at an angle to the initial line of flight. For conventional swing, the ball swings in the same direction that the seam is pointing. So a ball released with the seam angled towards the slip fielders will swing away from the batsman (outswinger) and one released with the seam pointed towards fine leg will swing into the batsman (inswinger). A great example of inswing can be found in the first innings of the fourth Test when Marcus Trescothick was bowl
