【分析解答题】Stumped RawalpindiHe has a normal head, but nestling between his massive shoulders it seems small. He is ShoaibAkhtar, "the RawalpindiExpress", the fastest recorded bowler of a cricket ball in history.And right now, before a small but baying crowd at the RawalpindiCricket Ground, he is steaming towards this correspondent. From 22 yards, Mr.Akhtar launches into the weirdly beautiful contortion that fast bowlers perform to hurl a six-ounce lump of cork and leather at up to 100mph. Half a second later, the ball demolishes the stumps.For over two centuries, cricket has been played according to a largely unwritten code of honour for the practical reason that its laws are too complicated for officials to enforce to the reality.But technology has been rewriting the old etiquette.And according to some recent research, one of cricket’’s most basic laws is untenable, and now the game is in turmoil. According to law 24. 3, bowlers may not straighten their arm in the final act of delivering the ball. This leads to Mr.Akhtar’’s brutal run-up and elaborate action as alternative means of generating pace on the ball. The centrality of law 24.3 to cricket — and the virtual impossibility of policing it — is reflected in the game’’s etiquette. To accuse a bowler of throwing the ball is one of the gravest insults in the game; yet now such accusations are flying thick and fast.Mr.Akhtar, the first man to bowl a delivery timed at 100mph, is one of a number of modern stars recently reported with "suspect actions". These rulings followed research into biomechanics that match officials had hoped would vindicate their decision.The University of WesternAustralia’’s School of Human Movement has been investigating cricket biomechanics.In 2003, a study by Marc Portus, at theAustralian Institute of Sport inCanberra, filmed a number of fast bowlers in action using a dozen cameras recording 250 frames per secon
D、They showed that virtually all bowlers straighten their arm, or throw, to some extent. Mr.Akhtar flexes his arm more than most only because he is extremely double-jointe
D、And to confuse matters further, a brilliant Sri Lankan spin bowler, Muttiah Muralitharan bowls with a crooked arm only because a congenital condition prevents him straightening it fully.In an effort to restore sanity to matters, bowlers are now allowed a varying margin for error depending on the pace at which they bowl. Thus, fast bowlers are legally allowed to straighten their arm by 10°, medium pacers by 7.5° and slow bowlers by 5°.But even this innovation has been rapidly undone. Last month, for the third time in his illustrious career, and even though poised to break the all-time wicket-taking record, Mr. Muralitharan was reported with a suspect action. Though Mr. Muralitharan was previously cleared by biomechanics, anEnglish match official questioned the legality of a wicked addition to his armoury of top-spinners, off-spinners and leg-spinners.

【分析解答题】How to increase sales Published online： Nov 9th 2006 From TheEconomist print edition How shops can exploit people’s herd mentality to increase sales 1.
A、TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intendeD、Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is， how ants， bees or any social animal， including humans， behave in a crowd) can be used to influence what people buy. 2.At a recent conference on the simulation of adaptive behaviour in Rome， Zeeshan-ul-hassan Usmani， a computer scientist from the Florida Institute of Technology， described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted： for instance， by placing everyday items such as milk and eggs at the back of the store， forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes， also of the Florida Institute of Technology， set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that， if a certain product is seen to be popular， shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying. 3.Enter smart-cart technology. In Mr Usmani’s supermarket every product has a radio frequency identification tag， a sort of barcode that uses radio waves to transmit information， and every trolley has a scanner that reads this information and relays it to a central computer.As a customer walks past a shelf of goods， a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high， he is more likely to select it too. 4. Mr Usmani’s “swarm-moves” model appeals to supermarkets because it increases sales without the need to give people discounts.And it gives shoppers the satisfaction of knowing that they bought the “right” product—that is， the one everyone else bought. The model has not yet been tested widely in the real world， mainly because radio frequency identification technology is new and has only been installed experimentally in some supermarkets.But Mr Usmani says that both Wal-Mart inAmerica and Tesco inBritain are interested in his work， and testing will get under way in the spring. 5.Another recent study on the power of social influence indicates that sales could， indeed， be boosted in this way. Matthew Salganik ofColumbia University in New York and his colleagues have described creating an artificial music market in which some 14，000 people downloaded previously unknown songs. The researchers found that when people could see the songs ranked by how many times they had been downloaded， they followed the crowD、When the songs were not ordered by rank， but the number of times they had been downloaded was displayed， the effect of social influence was still there but was less pronounceD、People thus follow the herd when it is easy for them to do so. 6. In Japan a chain of convenience shops called RanKing RanQueen has been ordering its products according to sales data from department stores and research companies. The shops sell only the most popular items in each product category， and the rankings are updated weekly. Icosystem， a company inCambridge， Massachusetts， also aims to exploit knowledge of social networking to improve sales. 7.And the psychology that works in physical stores is just as potent on the internet. Online retailers such asAmazon are adept at telling shoppers which products are popular with like-minded consumers.Even in the privacy of your home， you can still be part of the swarm.

【分析解答题】Computing is driving the philosophical understanding of quantum theoryFor evidence of the power of simplicity, you need look no further than a computer.Everything it does is based on the manipulation of binary digits, or bits-units of information that can be either 0 or 1. Using logical operations to combine those 0s and Is allows computers to add, multiply and divide, and from there go on to achieve all the feats of the digital age.But at each step of the complex operations involved, each bit has a definite value.The same cannot be said of many properties in quantum physics, such as the spin of an atomic nucleus or the position of an electron orbiting such a nucleus.At a small scale, such properties can have more than one value at once. In 1994, Peter Shor, a mathematician then atAT&T’’sBell Laboratories in New Jersey, realised that a computer that used such quantum properties to represent information could factorise large numbers extremely quickly. This is an important problem, because much of modern cryptography is based on the difficulty of factorising large numbers -- so being able to do so quickly would render many modern codes easily breakable. Then, in 1996, a colleague ofDr Shor’’s atBell Labs, Lov Grover, showed that such a quantum computer would be able to search through an unsorted database much faster than an ordinary computer -- another important application.With these insights, quantum computing, which had first been thought of as a possibility in the early 1980s, became a hot topic of research. It was clear to many physicists that using "qubits" -- which, unlike ordinary bits, can exist in a "superposition" of the values 0 and 1 simultaneously -- might yield an exponential improvement in computing power. This is because a pair of qubits could be in four different states at once, three qubits in eight, and so forth. WhatDr Shor andDr Grover showed was that the improvement, if the technological hurdles could be overcome, would be not hypothetical, but real, and useful for important problems.The technology necessary to manipulate qubits, in their various incarnations, is challenging. So far, nobody has managed to get a quantum computer to perform anything other than the most basic operations.But the field has been gathering pace, and is the topic of much discussion among the scientists gathered in Montreal for the annual March meeting of theAmerican Physical Society, the largest physics conference in the worl
D、There are currently several different approaches to quantum computing, all of which rely on fundamentally different technologies, including ultra-cold ions that are cooled by lasers, pulses of laser light, nuclear-magnetic resonance and solid-state devices such as superconducting junctions or quantum dots (which are confined clouds of electrons). What all these technologies have in common is that they can be used to invoke and exploit the bizarre phenomenon of superposition.Superposition is not simple. Though a qubit may, for a while, be in a state of superposition between 0 and 1, it must eventually choose between the two.And in even the best quantum computers, that choice, or "decoherence", happens in a fraction of a millisecon
D、Just how the choice is made, and how to prolong the preceding period of "coherence" that allows quantum computations to be made, constitute a long-unexplained gap at the heart of modern physics. For nearly 80 years, since the inception of quantum theory in the 1920s, most physicists were content to gloss over the process. What is perhaps surprising is that the technological challenge of quantum computing is now a driving force behind efforts to understand the most abstract and philosophical underpinnings of quantum mechanics.
