why are scores 15, 30 and 40 and not 45 in tennis?
93051
When the game originated, they used a clock to keep score.  For the first point, they moved the minute hand to 15, then 30, then 45, then back to 0 for game.  Overtime 45 was shortened to 40 for ease.

Yeh, 423 has more dimples than 408, otherwise it's just very technical on aerodynamic that doesn't make sense to most golfers. You need to hit at near zero handicap to really feel the different in golf balls, let alone the number of dimples.

No its "unique" to the Us open, due to the fact its run by the USGA rather than the PGA, plus if you saw, its only a par 70 not a par 72 as most other courses are yet it was exactly the same length as a par 72, just set up to be 2 strokes shorter, hence the fact all the scores were in "over" par!!!

The scoring system for golf is actually very simple.\n\nEach hole on every course is given a "par" score..in other words the number of shots it should take you to get your ball from the tee to the hole. The par for a hole depends on its length and difficulty. \n\nA "bogie" is  the par score for a hole plus one..so if you take 5 shots on a par 4 hole, thats a bogie..and thats not good!\n\nA "birdie" is the par score for a hole minus one..so if you only take 3 shots on a par 4 hole, that's a birdie...and that's good!\n\nThe winner is the golfer who take the fewest shots to go round all 18 holes on a course.\n\nThe best way to learn is to play,  or just watch the big tournaments on the TV. You will soon pick it up.

Golf is a game in search of perfection. However, there are very few sports in which perfection can be attained (i.e. 300 in bowling).\n\nAdditionally, golf courses have a number that is considered normal, or "par." The idea is to get the least amount of strokes under par... the lowest score wins. \n\nThink about this... there are a multitude of variables on a golf course as well as with any player at any given moment. For example, a golf course may be wet the next morning after an evening rain. You might have done really well on the dry course the day before, however, since the weather changed, the conditions are different and scores will be altered. \n\nAlso, strength and fatigue have a lot to do with a golfer's capability to score well. As with any sport, training is necessary. However, strength may be lost at one point in time because of something simple as a bad night's sleep or in Tiger Woods' case, a father who is ailing from cancer. \n\nAnyways, putting a golf ball in a 3 1/2" hole from 150-600 yards away in one shot is very difficult. There are limitations that humans have... if one person can hit the ball 450 yards, he's not going to be very accurate. However, another person may be able to hit the ball only 300 yards but may be able to get around the green like a veteran pro.\n\nHope this explanation helps!

The dart board is set up the way it is in order to make the game challenging. If 20's, 19's, and 18's were right beside each other, everyone would have a 60+ point-per-dart average. Putting the one and five beside the 20, forces you to be accurate.\n\nIt also gives an advantage to darters who think before throwing. Sometimes in a game of '01, there are two sections beside each other that will both be beneficial. For example, if you have 35 left (in a double out game), you throw for the 19/3 pies. Three leaves 32, and 19 leaves 16. The double 16 and double eight are right beside each other as well.

The draw is divided into two parts: seeded players, and the rest of the field.\n\nFor Grand Slam tournaments, the field is 128, and there are 32 seeded players.  The seeds are allocated by the ATP (men) or WTA (women) ranking released in the previous week -- except Wimbledon, which has subjective seedings.\n\nThe 1st seed is in slot 1.\nThe 2nd seed is in slot 128.\nSeeds 3-4 are drawn into slots 33 and 96.\nSeeds 5-8 are drawn into slots 32, 64, 65, and 97.\nSeeds 9-12 are drawn into slots 17, 49, 80, and 112.\nSeeds 13-16 are drawn into slots 16, 48, 81, and 113.\nSeeds 17-24 are drawn into slots 9, 24, 41, 56, 73, 88, 105, and 120.\nSeeds 25-32 are drawn into slots 8, 25, 40, 57, 72, 89, 104, and 121.\n\nThe rest of the field is then drawn to the remaining slots.\n\nFor tournaments with 64 players, there will be 16 seeds.  For 32 players, 8 seeds, with the same basic structure.\n\nThere are tournaments with 96 or 48 players (or other numbers), in which case the top seeds will receive a bye in the first round.

Rule 1. Opponents stand on opposite sides of the court. The player who delivers the ball to start the point is called the server. The player who stands opposite and cross-court from the server is the receiver.\n\nRule 2. The right to serve, receive, choose your side, or give the opponent these choices is decided by a toss of a coin or racquet. If the choice of service or receiver is chosen, the opponent chooses which side to start.\n\nRule 3. The server shall stand behind the baseline on the deuce court within the boundaries of the singles court when playing singles and within the doubles sideline when playing doubles. See court dimensions. All even points are played from the deuce court and odd number points played from the advantage court. The server shall not serve until the receiver is ready. Serves are made from the deuce court to the opponents service box on the deuce court. Advantage court to advantage box. If the server misses his target twice, he loses the point. If the ball hits the net and goes in the correct service box, another serve is granted. If the server steps on the baseline before contact is made, the serve is deemed a fault.\n\nRule 4. The receiver is deemed ready if an attempt is made to return the server's ball. The receiver can stand where he likes but must let the ball bounce in the service box. If the ball does not land in the service box, it is deemed a fault and a second serve is given. If the ball is hit by either opponent before the ball bounces, the server wins the point.\n\nRule 5. The server always calls his score first. If the server wins the first point, he gets a score of 15. Scoring is done like a clock. See example below. Love means zero in tennis. The second point is called 30. The third point is called 45 (now-a-days known as 40) and game is won when the score goes back to love. If the score is 40-40, also known as deuce, one side must win by two points. Advantage-In means if the server wins the next point, he wins the game. Advantage-Out means the receiver has a chance to win the game on the next point.\n\nLOVE 15-30-40\n\nRule 5. After the game, the opponents serve. Games equal 1. The first to win 6 games, by two, wins the set. The first to win 2 sets wins the match. If the score is 6-6, a tie-breaker is played. This is scored by one's. The first team to score 7 points winning by two wins the set. The tiebreaker continues until one side wins by two. Hence, Game-Set-Match.\n\nRule 6. If the ball goes into the net, or outside the boundaries of the court, the player who hit that ball loses the point. If the ball hits the net during the point and goes into the opponents court, the ball is in play. A player loses the point if he touches the net, drops his racquet while hitting the ball, bounces the ball over the net, hits a part of the surroundings such as the roof, or a tree, the ball touches him or his partner, he deliberately tries to distract the opponent.\n\nRule 7. A let is called during the point if a ball rolls on the court or there is a distraction from someone besides the players on the court.\n\nRule 8. A ball that lands on the line is good.\n\nRule 9. If players serve out of turn or serve to the wrong person or court, the point or game will stand and order will be resumed following the point or game.\n\n\nThe server is required to keep his feet in nearly the same position during the serve. The server's feet may be raised off the ground, but walking or running are not permitted, so as to prevent the opponent being misled as to where the serve will originate. Breaching this rule or exceeding the permitted part of the court constitutes a ''foot fault''.\n\nIn a legal service, the ball travels over the net without touching it and into the diagonally opposite service court. If the ball hits the net but lands in the service court, this is a ''let service'', which is void, and the service is attempted again. If the first service is otherwise

The old rule of thumb was to grab the middle of a racket handle and warp your fingers around and there should be a one finger width gap between your fingers and the palm of your hand.  Some players that prefer a western forehand will even get a slightly smaller grip so it is easier to whip the racket head through the stroke for extreme topspin.  Some serve and volley players like their handles a little bigger so the racket doesn't twist in their hands on off-center volleys.  This is just a general rule, becuase I have also seen extreme topspin players that like larger grips and serve and volleyers with smaller grips.  The one finger rule is a good place to start and then see if you want more spin or better feel on the volley and adjust accordingly.  I prefer my own grip slightly smaller than the norm because I find it easier to get more bite/spin on my 2nd Kick serve.

It has to do with the clock. 15 minutes,30 minutes and instead of 45 minutes which is a odd figure ; it is said 40; and at the end of the game 60 means 0 hour or  game. So  the sequence is 15 , 30 , 40 , game. Love means 0 and deuce is double 0 or 00.\n             Advantage maverick, your service sir!\nEdit-: The answer of 'vector4tfc' has substance in it but still the counting has origin in the answer given by me as it is published in some sports book long ago.

in volleyball rally scoring, a point is won on every play, with every serve. in the traditional scoring, only the serving team can win a point. if the non-serving team wins the ball, they get the opportunity to serve. they then have the chance to get a point. rally scoring is played to 25 because the game is so much faster, and traditional scoring is played to 15, because it takes longer.

Since August 2006, the new scoring system is adopted.\nA point shall be added to a player's score whenever he wins a rally.\nA match consists of the best of three games; a game is won by the first player to score 21 points, except if the score reaches 20 points each; in this case, play shall continue until one player either achieves a two point lead (such as 24-22), or his score reaches 30 (the score shall not extend beyond 30: 30-29 is a winning score).\n\nIn singles, the server shall stand in his right service court when his score is even, and in his left service court when his score is odd; his opponent shall stand in the diagonally opposite service court.\n\nIn doubles, the players shall remember their service positions from the previous rally; the receivers shall remain in the same service courts. When a receiving pair wins a point and thereby regains the service, they shall not change their service court positions. If their new score is even, then the player in the right service court shall serve; if their new score is odd, then the player in the left service court shall serve. Thereafter, if they continue to win points, the server shall alternate between the service courts, so that he serves to each receiver in turn.\nEach team no longer has second server.  Now the score determines which side the server should be (right or left).\nGood luck and have fun.

The reason is because the rules say in England that a game needs to have a least of 5 points to be consider a game with a difference of two points to consider the winner of that specific game.\nIt all goes back to the British
