Tsunamis are powerful waves caused by underwater earthquakes or eruptions that can crashover ten stories tall into a coastline.海啸是由海底的地震或者火山喷发引起的足以把一个十层高楼淹没的强大海浪。If you were sailing far from shore, how would you feel about a tremendous tsunami heading your way?如果你正远离海岸航行,这时遭遇了海啸,是什么样的感觉呢?Actually, you wouldnt notice a tsunami at all.事实上,你根本不会注意到海啸。In deep water, a tsunami raises the oceans surfaceonly about one or two feet—much less than ordinary ocean waves.在深海中,海啸只会掀起一或两英尺的海浪-远远低于普通的海浪。Whats more, it takes up to an hour for a single tsunami to roll by.更重要的是,一次海啸最多一个小时就过去了。How can a wave be so deadly to a coastline, but so tame inthe open ocean?为什么对于海岸如此致命的海浪在公海中如此温驯呢?The energy of a wave has more to do with how deep the water churns than how tall the waverises.海浪的力量与水层波动的深度而不是海浪的高度有关。Ordinary waves can be rather tall, but they dont go very deep.常波可能很高,但是它们水体波动的深度并不深。Whats more theres nevermuch distance between one ordinary waves crest and the one following it.更重要的是常波前后的波峰之间并没有太大的距离。The distance betweenwaves is called “wavelength,” and its another secret of a tsunamis strength.波之间的距离被称为“波长”,这是海啸力量的另一个秘密。While ordinary waves only tug at the surface water, tsunamischurn the water all the way to thedeepest ocean floor!尽管常波只是在水表面生成,但是海啸可以在最深的海底引起水层波动使其产生。They also have very long wavelengths—a hundred miles or more.它们同样有很长的波长一百英里或更多。Although tsunamis raise the surface only a foot or so in deep water, they carry a lot of energy.虽然海啸通过深海中的水层波动只能提升水平面一英尺左右,但是它们带来了大量的能量。When a tsunami approaches a coastline, the water gets shallower.当海啸接近海岸线时,水的深度逐渐变浅。This causes friction at the frontof the wave and slows it down.导致波前擦,使其速度变慢。The faster moving back of the wave piles into the slower front,squeezing the whole hundred mile tsunami like an accordion.快速前进的波浪与前面速度较慢的波浪重叠,像手风琴那样挤压这些整个百里长的海啸。Just as a rug will crumple and rise if its scrunched by an opening door, the tsunami gets taller.正如由于门开时被压住而弄皱卷起的地毯,海浪就越来越高。By the time it hits the beach, it canbe a hundred feet high!当它到达海滩的时候,它可以达到一百英尺。 /201408/320556When a vegetable is growing, it protects itself from insects by producing chemical nutrients thatmake it taste bad or seem repellant to predators.蔬菜在生长的过程中会产生化学养分,使其口感变差或让捕食者排斥,以此来保护自己免受虫害。Some of these nutrients—in particularphytochemicals—have been shown to fight cancer in people.这其中的一些化学养分,特别是植物素,已经被明可以用于人类抵抗癌症。Whats more, many vegetables areable to anticipate when insects will attack, and will ramp up its defenses accordingly.并且,许多蔬菜都能够提前预见昆虫的进攻,并相应地增加自身防御力。Even after vegetables are harvested and theyre no longer fighting insects, these garden wonderscan still be made to produce more nutrients at certain times.即便蔬菜已经丰收,无需再抵抗昆虫,这些菜园中的奇迹依旧能在某些时候产生较多的营养素。This is done by varying a vegetableslight exposure to simulate the experience of night turning into day.方法就是通过改变蔬菜的光照量来制造出昼夜交替的效果。Studies have shown thatvegetables stored this way produce more phytochemicals during the light cycle.研究表明这种方式下储存的蔬菜会在光照周期中产生更多的植物素。So eating vegetables during this golden period means youre getting more nutritional value!Exactly.所以在这段黄金时间吃蔬菜意味着你能获得更多的营养价值!Its not yet clear how people might be able to activate these nutrition-packed properties at home.至于人们如何能在家就激活这些储存的营养素,还不甚清楚。Perhaps simply storing veggies in the dark and then subjecting them to a flash of light is enoughto trigger the process.也许只是简单地将蔬菜储存在暗处再给予它们一闪光亮就足以触发这一过程。Or it could be more complex.或者还会更复杂。In any case, more research could help us findways to eating vegetables even more helpful.无论如何,更多的研究会帮助我们找到使蔬菜营养价值最大化的方法。 /201403/278305

By the mid 1800s, the horse and the cowboy had come to symbolize the wild west. And of course, with the cowboys came cattle. As the bison quickly vanished from the landscape, cattle filled their place. 到19世纪中叶,马与牛仔成为了辽阔西部的象征。当然,既然提到牛仔,那么一定会提到牛。随着北美野牛快速地从大陆上消失,家牛取代了他们的位置。Meanwhile increasing numbers of the tame horses escaped into the wild. These feral horses became known by the Spanish name, mustang. They put extra pressure on the dwindling bison numbers by competing for their grazing sites and drinking holes. 与此同时,越来越多的被驯的马儿逃到了西部。这些野马成为了西班牙语中所称的“木斯塘马(mustang)”,它们数量的上升也给北美野牛的存活增添不少压力,它们与北美野牛争抢草原和水源。Mustangs form social groups led by a dominant stallion, echoing their prehistoric relatives that lived here during the Ice Age. 木斯塘马是一个群居的种族,由一匹占统治地位的公马领导整个族群,这一点和它们冰河时代栖息于此的史前亲戚相同。Bred to carry the weight of a rider, mustangs are larger than those early wild horses, but they still display the same kind of behavior. 木斯塘马是供人骑乘的,从体重看,他们比那些之前的野马体型更大,但是两种马匹的行为有很多相同之处。By the early 1800s, the wild horse was well and truly back in North America, but how did other wildlife on the continent survive alongside growing human populations?19世纪早期,野马真正回归北美大陆,但是大陆上其他的野外生物是怎么在人类数量速度增加的情况下存活的呢?Some wild creatures did the reverse of mustangs by becoming tame and choosing to live close to people. The purple martin became an unofficial mascot for native inhabitants in the eastern half of the continent. Here people erected special nesting sites to encourage the birds to stay.一些野外生物也和木斯塘马一样选择了追随人类并被其驯。在大陆的东半侧,北美洲紫燕在当地居民眼中是一种吉祥物。在这里,人类为紫燕建巢并希望这些鸟儿留在这里。英文文本来自普特英语,译文属未经许可不得转载。201311/266549

Business商业报道Takafumi Hories comeback堀江贵文的回归Up, up and away升高,升高再升高The controversial entrepreneur remains popular, brash and ambitious这个有着很大争议的企业家依旧很受欢迎并且野心勃勃IN 2005 Takafumi Horie, then president of Livedoor, an internet firm, joined the X PRIZE Foundation,2005年,互联网公司活力门的总经理堀江贵文加入了X奖基金会。a charity which gives cash for innovative projects such as space tourism.X奖基金会是一个慈善组织,这个组织会为一些创新科技项目提供资金,如:太空旅行。Joining forces with the likes of Larry Page and Elon Musk, co-founders of Google and PayPal respectively, was a typically bold move by the self-styled boy billionaire from Fukuoka.加入一个有拉里佩奇和埃隆?马斯克这样的人的组织,无疑是这个福冈不为人知的亿万富翁小子的一项勇敢举措。拉里佩奇和埃隆?马斯克分别是谷歌和贝宝的合作创建人。Instead of going into orbit, however, Mr Horie went behind bars.不像其他人那样走的一帆风顺,堀江贵文曾在监狱过刑。He was arrested in Japans biggest financial scandal of the decade.他被捕的原因是卷入了日本数十年来最大的财政丑闻。Now, however, he is out on parole, and says he will soon launch a low-cost space-tourism business using a Russian capsule.但是现在,他假释出狱,并且表示,他马上就会使用俄罗斯研发的一种太空舱经营一个低成本的太空旅行企业。He has completed several test launches.他已经进行了多次发射演练。A large Japanese firm is on the verge of sponsoring a flight next year, he says.他说,日本的一家大公司已经准备明年投资一架飞机。Other investors, he claims, are standing by.并且声称,其他的投资者也都蠢蠢欲动了。This time the money will come not from inflating the earnings and shares of Livedoor, for which Mr Horie was sent down,现在这个时期,对于像堀江贵文这样子被开除的人来说,钱不是那么容易就能从活力门的股份和通货膨胀的工资中挣到,but from a dedicated following of 20- and 30-somethings who pay to hear his thoughts via a monthly digital magazine.但是他却可以从一大批忠心的追随者中赚到钱,那些追随者会订电子月刊付钱听他的想法。He has almost a million followers on Twitter. Social media and crowdfunding platforms, he says, make it far easier now to launch new businesses.他在推特上已经有了将近一百万的追随者。他说,社交媒体和云募资平台使得创建新企业变得更加容易。Not even 21 months in a Japanese prison,绝不仅仅只是21个月在日本监狱生活,including solitary confinement, freezing temperatures and forced labour, were able to stop him entertaining an audience.这之中堀江贵文还被送到那种极度寒冷且被迫大量劳动的地方单独监禁,这种经历使得他不再用愉悦的口吻为自己的听众做讲解。From his cell he published two well-received books with gritty manga strips describing his new life:牢狱中,他在自己的小房间中出版了两本很受欢迎的书,书中他用日本漫画来描绘自己的生活:cleaning pubic hair out of toilets, being farted at by the senior prisoners he had to tend to, and having to surrender porn magazines to prison guards.清理洗手间的毛发,比自己早来的犯人冲着自己放屁,被迫向监狱看守交出自己的色轻杂志。He also dreamed up dozens of new-business ideas.他也在书中阐述了很多关于新企业的想法。Among the 30 or so earthbound plans are a new reality show where fans will pay to put their idols on television,大约有三十个切合实际的计划都是关于一个新的实体秀的,在这个实体秀中,粉丝需要付钱把他们的偶像放到电视上,a celebrity-chat smartphone application and a scheme to undercut the price of livestreaming to phones. Nothing too radical, then:付钱去申请一个和名人电话通话的机会,付钱去买更为廉价的主流音像资源到手机上。这之中没有任何一个特别激进的,然后:Japan, after all, is aly awash with social-media and smartphone start-ups.日本就会充斥着社交媒体和智能电话企业。As for his reception back into business life,至于他返回商业界的感受,Mr Horie jokes that everyone has welcomed me, except for the chairman of Fuji TV.堀江贵文开玩笑地说道:每个人都很欢迎我,除了富士电视套台长。Many people reckon the entrepreneur was punished harshly mainly because he tried to win control of the big broadcaster, and because he flaunted his wealth.很多人推测堀江贵文之所以被如此严厉的惩戒主要是因为他曾经试图去控制广播公司,而且他还总是去炫耀自己的资产。The authorities usually treat accounting fraud more leniently. In July a group of executives at Olympus, a camera-maker, received suspended prison sentences for a far larger scheme.政府惩罚做假账的都比这轻。七月,奥林巴斯的一组高官由于一个很大的商业阴谋而被判缓刑。Mr Horie, now 40, says he is trying to forget what happened.四十岁的堀江贵文说他正在试图忘记所发生的不好的事情。It will be hard for his generation to do likewise.但这对于他那一代人来说却很难。William Saito, a serial entrepreneur who travels the country encouraging graduates to start new businesses, says he has spent the past five years trying to undo the dispiriting effect of Mr Hories fall and punishment on young people.连环创业者威廉斋藤游遍全国去游说毕业生创业,他说,他过去五年都在尝试解开堀江贵文的失败为年轻人们带来的负面效应。A successful new venture would help greatly.一个成功的新企业将会起到很大的帮助。 /201309/255982

Business商业报道Motivating workers激励员工Ranked and yanked评级与封杀Firms that keep grading their staff ruthlessly may not get the best from them.那些总是无情地把员工分个三六九等的公司或许并不能得到最好的效果。Mayer: whos for the chop next?Mayer:谁是下一个要开除的?IT IS a brutal management technique in which bosses grade their employees performance along a vitality curve and sack those who fall into the lowest category.老板们对雇员们的表现按照活力曲线来评定,然后把最差的一些炒掉鱿鱼的管理方法实在非常残酷。Known as ranking and yanking, it had its heyday in the 1980s and 1990s.这个被称为评级与封杀的做法在19世纪80和90年代达到了全盛期。In America its popularity faded somewhat after it was seen to have contributed to the fall of Enron.在美国,实施该策略的公司因其被认为促成了安然公司的破产曾大量减少,Now it is back in the headlines.不过现在这个字眼又重新见诸报端。On November 8th All Things D, a tech-industry website, reported that Yahoo staff are increasingly unhappy about a quarterly performance review introduced last year by the new boss, Marissa Mayer.在11月8日,技术产业网站All Things D报道说,雅虎的员工们对于新老板Marissa Mayer去年引入的季度表现评估正日渐不满。The grading exercise is said to have cost 600 of them their jobs in recent weeks.据说,这种评估行为导致几周内就有600人没了工作。Four days later, Microsoft announced that its own, equally unpopular system was being scrapped.四天以后,微软宣布废除它自己同样不受欢迎的评价系统。In a memo, Lisa Brummel, Microsofts head of human resources, said there would be no more ratings and no more curve.在一份备忘录上,微软人力资源主管Lisa Brummel说道,再也不会有打分和曲线了。The firm would implement a fundamentally new approach, designed to encourage teamwork and collaboration.微软将会启用一个用来鼓励团结合作的崭新的方法。Many firms, from Amazon to PwC, still use some version of what management theorists also call stack ranking to sort the sheep from the goats in their workforce.从亚马逊到普华永道的许多公司依然在使用许多管理理论家称作员工排序的方法来挑选出不够格的员工。However, many of them enforce it more flexibly than seems to have been the case at Microsoft or Yahoo.然而,其中大多数的公司在实行时要比微软和雅虎这些公司有弹性的多。Even General Electric, which pioneered the technique during the uncompromising reign of Neutron Jack Welch, has since softened its approach.甚至在中子弹杰克韦尔奇治下首先采用这种管理方法的通用电气近年来也软化了实行方法。The reason such gradings have not died out entirely is because employers still need to find ways to fairly evaluate their employees and have a basis for compensation differences, says Robert Kaplan of Harvard Business School.这种评分策略没有完全消失的原因在于老板们仍然需要找到公平评估雇员的方法并据此确定报酬差异。This is especially true when there is a wide gap between the remuneration of top performers and the rest.当顶级员工的工资和其他人差的很多的时候,这尤其显得很重要。To avoid lawsuits claiming unfair discrimination, firms need to be able to show they have a clear basis for decisions on pay and bonuses.这话来自于哈佛商学院的Robert Kaplan。为了避免不公待遇和员工歧视的诉讼,公司在决定酬劳和福利的时候需要有明确的根据。Ranking and yanking is more logical in investment banks, law and accountancy firms and big consultancies:评级和封杀在投资、法律和会计公司以及大型咨询公司这些行业中要更合理一些:their business model is, in a sense, built on recruiting large numbers of junior staff and motivating them with the prospect of becoming a partner, even though in practice only a few of them can ever make it.他们的业务形式在某种程度上就是建立在招收大量新员工然后用成为合作人的目标激励他们努力工作,虽然实际上只有极少数人能够做到。In other types of business, the evidence suggests that it may work at first, if a firm needs to cut away dead wood.但在其他行业中,有据显示这个方法在公司想要除去公司的赘余部分时还是能管用一段时间的。But the benefit can disappear and turn into a cost if the ranking and yanking is done repeatedly, says Denise Rousseau of Carnegie Mellon University.但是如果重复进行下去,就会由使公司收益变为带来损失。卡耐基梅隆大学的Denise Rousseau如此说道。You can quickly end up with the people in the bottom quartile being average performers rather than poor performers, she notes.很快,处在评估表底部的人就会是一般员工而非业务糟糕者她解释道,There is nothing wrong with being average in an above-average workforce.在一群极其优秀的员工中成为普通一员可没什么不对的。A lot of good work is done by average people.众多的优秀工作都是由普通人做成的。If a large proportion of the workforce doubt the fairness of the grading system, and fear being among an arbitrarily imposed a of underperformers, many may try to jump before they are pushed:如果员工中较大一部分人怀疑评价体系的公正性,并且担心被随机地划分为不合格员工,其中不少就会尝试在被开除之前跳槽:staff turnover may thus be higher than is desirable.人员流动程度就会比期望的更大。Worse, employees may look for ways to game the system, as happened at Enron, where workers conspired to inflate their results to secure their bonuses or escape the axe.更糟的是,雇员会想法设法利用体系的规则,正如安然事件中发生的那样,员工们串通起来夸大自己的成果来保自己的奖励或是避免被开除。That is not the sort of teamwork and collaboration that is wanted.这可不是我们想要的那种团结合作。 /201311/265975
