;Could you hear me?; Stephen Hawking asked in his iconic computer-synthesized voice, getting a cheerful ;yes; from hundreds of people in a speech hall at the Hong Kong Science Park.“你们能听到我说话吗?”当史蒂芬·霍金标志性的电脑合成嗓音传来,香港科技园演讲大厅的上百号人兴奋高呼:“可以”。;I can hear you, too,; in seconds he replied, this time triggering from the audience even more exclamations: ;Wow, cool;!“我也可以听到你们!”几秒种后,霍金回应道,并引来了现场观众又一阵惊呼:“哇塞!这简直太酷了!”This dialogue appeared to be a face-to-face chat, but according to the organizer, Hawking was actually sitting in front of a green screen in his office in Cambridge, only having his image beamed to a transparent screen in the hall in Hong Kong and presented to the audience as a digital human hologram.这段对话看似是一场面对面式的闲聊,但是组织方表示,霍金事实上是坐在剑桥办公室的一块绿幕面前,他只是将自己的影像投射到香港科技展厅的透明屏幕之上,以数字全息图像的呈现方式与大家见面。In the over-one-hour speech, Hawking talked about his life experience and research progress, shared his views on topics from the beginning of time to Brexit, and encouraged the audience to tackle difficulties in life just as how he did.在接下来一个多小时的谈话中,霍金谈到了自己的生活经历以及研究进程,也对从时间起源到英国脱欧等各类话题分享了自己的见解,同时鼓励观众像他一样勇于克生活中的各种困难。The speech included a touching account of the world-famous physicist#39;s early life, as well as flashes of his sense of humor.这段演讲谈及了这位世界知名物理学家令人动容的早年经历,同时还有展现了霍金幽默感的片段。Talking about how he almost lost confidence in life after his was diagnosed with a motor-neuron disease but regained momentum for continuing his research after meeting his future wife, Hawking said: ;If I want to get married, I need to finish my Ph.D. and get a job.;当谈到自己得知因患上肌肉萎缩性侧索硬化症而失去对生活的信心、却又在遇见妻子后重燃希望继续从事学习研究时,霍金调侃道:“我要想结婚,就得先念完士,找个工作。”When referring to his bestselling book A Brief History of Time, he joked: ;I am sure you have all it from cover to cover, so I shall be asking questions later.;当提到自己的畅销之作《时间简史》时,霍金开玩笑般说道:“我相信你们都已经从头到尾读过这本书了,我觉得一会儿我应该提几个问题。”This virtually-delivered speech was realized thanks to the augmented reality holographic technology, or HumaGram, as called by the developer ARHT Media on its website.这场“实时对话”的圆满完成都要归功于现实增强全息人像技术,开发商增强现实全息影像技术(ARHT)公司在其官方网站上也将其称之为“HumaGram”,即交互性人体全息影像技术。ARHT Media President and CEO Paul Duffy said he hoped to use this technology to ;bring; more outstanding figures to Hong Kong and provide inspirations for citizens here.ARHT公司的总裁兼首席执行官保罗·达菲表示,他希望可以通过使用这项技术令香港接触更多的杰出人物,为当地人民提供灵感与启示。 /201704/501870Twenty and thirty somethings aren't as healthy as their parentsThey should be in the prime of their lives. But instead, those in their twenties and thirties are in worse health than their parents, a British survey has found.Binge drinking, y meals and a lack of exercise all take their toll.As a result, the young are more likely to have migraines, catch a cold or become stressed than the over-55s.According to the research, those aged between 18 and 34 are three times more likely to have a cold or flu than the older generation.Nearly a quarter of the young regularly have headaches or migraines, compared to just 14 per cent of over-55s.And they are almost twice as likely to have high stress levels.The elderly also tend to eat more healthily. More than four in ten eat five or more portions of fruit or vegetables a day, double the number of young men and women.And when it comes to alcohol, 20 per cent of the over-55s don't indulge, while just 10 per cent of those aged 18-34 abstain.Six in ten of the elderly make fresh meals every day, compared to less than a third of the young.And while three-quarters of over-55s say they eat a balanced diet, just half of the younger generation does so.Less than a third of them regularly cook with fresh ingredients, compared to almost two-thirds of the older people.What is more, almost 10 per cent of them admit to eating y meals for every meal - and two per cent say they only eat at restaurants.The older generation is also more likely to take a healthy amount of exercise, with 12 per cent spending at least 30 minutes doing so each day.They may appear fitter, but only nine per cent of the young do that.Over-55s also try hardest to have at least six hours' sleep and plenty of fresh air, according to research done in the UK for fruit brand Florida Grapefruit.Chris Steele, the resident doctor on ITV's This Morning programme, said: "I have seen a rise in young people suffering from illnesses such as colds, flu and headaches."Long working hours, high stress levels and lack of exercise lead to people getting run-down and ill.[size+0](Agencies)他们应该正值人生的黄金时期。但英国的一项调查发现,二、三十岁的年轻人的健康状况还不如他们的父母。酗酒、吃方便食品、缺乏锻炼均对年轻人的健康造成了不良影响。所以,年轻人比55岁以上的人更易患偏头痛和感冒,而且更容易焦虑。该调查表明,18岁至34岁之间的人患感冒或流感的几率为他们父辈的三倍。近四分之一的年轻人经常患头痛或偏头痛,而这一比例在55岁以上的人中仅为14%。此外,年轻人精神压力过大的几率高出近一倍。年龄较大的人饮食习惯也更加健康,超过十分之一的人每天摄入五份或五份以上的水果和蔬菜,为年轻人的两倍。在55岁以上的受访者中,20%的人不酗酒,而在18岁至34岁的人群中,这一比例仅为10%。60%年龄较大的人每天做新鲜饭菜,而年轻人的这一比例还不到三分之一。在55岁以上的受访者中,有四分之三的人称自己饮食平衡,而仅有一半的年轻人这样做。此外,近10%的年轻人承认他们每顿都吃方便食品,2%的人称他们只会在去餐馆时吃这些东西。老一辈的人经常进行适度锻炼,12%的受访者每天至少锻炼30分钟。可能年轻人看起来比较健康,但仅有9%的人每天锻炼。该项为“佛罗里达柚”水果品牌开展的调查显示,55岁以上的受访者努力保每天至少六个小时的睡眠时间,并尽量让自己呼吸大量的新鲜空气。住院医生克里斯#8226;斯蒂尔在ITV《今晨》节目中说:“我发现,现在有越来越多的年轻人患感冒、流感和头痛等病症。”“工作时间长、精神压力大和缺乏锻炼是导致人们健康状况下降和生病的主要因素。” /200802/26752In an unusual move that may have serious *implications for both the US presidential election and US-Russian relations, Washington has officially accused Moscow of *interfering in the showdown for the US presidency between Hillary Clinton and Donald Trump.日前,美国已正式指控俄罗斯在美国大选的关键时刻,干扰希拉里#8226;克林顿和唐纳德#8226;特朗普之间的竞选。而这个不寻常的举动,可能将严重影响美国总统选举和俄美关系。Although the US Democratic Party said as early as June that Russian government hackers were behind the major leak of emails that embarrassed the Party leadership and Hillary Clinton, the White House did not immediately confirm the accusation, or join the *condemnation of Russia.美国民主党早在今年6月就曾表示,使党内领导层和希拉里#8226;克林顿陷入窘境的邮件门事件,其幕后黑手便是俄政府的黑客,然而白宫却没有立即明确表态,也没有对俄罗斯进行谴责。But on Oct 7, just two days ahead of the second US presidential debate between Trump and Clinton, the Obama administration made public the official accusations.但到了10月7日,就在希拉里和特朗普将要进行第二轮美国总统大选辩论的前两天,奥巴马政府公开宣布了官方指控。The US Intelligence Community is confident that the Russian government directed the recent compromises of emails from US persons and institutions, including from US political organizations, said the administration in a statement. These *thefts and disclosures are intended to interfere with the US election process.美国情报局确信,俄罗斯政府操控了近期的美国政治组织、个人及机构的邮件信息泄露,美方在一份声明中表示,这些盗窃和曝光行为意图干扰美国的选举进程。Russia has denied any involvement in the hacking. 对此,俄罗斯方面否认参与任何黑客行动。Just hours after the accusations were published, whistle-blowing site WikiLeaks released thousands of emails stolen from a Clinton campaign official, including some that contained *excerpts from speeches Clinton made to Wall Street banks. 而就在美方发布指控几个小时后,维基解密网公布了一位希拉里竞选团队成员所收到的数千封电子邮件,其中包括希拉里在华尔街演讲的摘录。The *revelations are expected to bring *embarrassment to Clinton, despite currently leading Trump by a comfortable *margin in the polls.尽管目前希拉里在民意调查中持率略胜特朗普一筹,但这些披露预期将会使她深陷窘境。 /201610/472509If you thought Russia#39;s recent efforts to prevent rain in the sky from dampening holiday spirits represented the ultimate in scientific stage management, you ain#39;t seen nothing yet.如果你认为俄罗斯最近为了阻止雨水毁掉节日氛围的努力是高科技舞台管理的极限(为避免五一期间下雨,俄罗斯花百万美元“播云”),那么跟日本人相比,简直小巫见大巫了。A Japanese research company called ALE Co. (aka Star-ALE) is bidding to put on a sensational pyrotechnics display for the opening ceremony of the 2020 Summer Olympics in Tokyo. But this is no regular fireworks show: ALE Co.#39;s #39;Sky Canvas#39; is an artificially created meteor shower – uh-huh – which would see hundreds of tiny, coloured fireballs rain down over the host city.一家叫做ALE CO的日本公司正在筹划在2020东京夏季奥运会开幕式上进行一场举世无双的烟火表演:他们的“天空画布”项目将上演一场人造流星雨,届时将有数百颗色火球从天而降。According to a report at industrial design site Core 77, if ALE Co. has its way, this amazing concept would result in the human-made shooting stars being visible from well outside of Tokyo too, with the next-level pyrotechnics expected to be viewable from up to 100 kilometres away from the city.根据日本工业设计网站Core 77的报道,如果ALE Co得以实施这一计划,这场人造流星雨在东京以外的地区都可以看到,观察半径达到100公里。But how does it all work? ALE CO. says it can ;artificially recreate; the process of natural shooting stars by sending up a satellite into orbit carrying a payload of between 500 to 1,000 specialised pellets called ;source particles;.但是它的原理是什么呢?ALE Co.说他们可以“人工再现”天然流星雨的过程。通过发射一颗卫星进入轨道,搭载500到1000颗叫做“源粒子”的小球。Once the particles – composed of chemicals designed to emit flames in various colours – are discharged from the satellite, they#39;d travel around Earth until they enter the atmosphere and begin to burn up. With numerous particles being discharged at the same time, the company says it can create a safe, on-demand meteor shower for the wonderment of the crowds below.这些粒子中包含的化合物可以制造出五颜六色的火焰。粒子从卫星发射出来以后,它们会环绕地球飞行,直到进入大气层,开始燃烧。据该公司称,同时发射大量的粒子,就可以为地上的观众制造一场安全的按需定制的流星雨。But wonderment comes at a cost, and in this case, that cost isn#39;t cheap. Core77 reports that each combustible pellet comes in at about US,100 to produce, and that#39;s not including the costs involved in actually launching the Sky Canvas satellite. Ouch.效果这么炫酷,烧钱肯定是难免的。Core77报道说每一个可燃烧的粒子的制造成本是8100美元,而且这还没算发射“天空画布”卫星的成本。The company has tested its source particles in the lab, using a vacuum chamber and hot gases to simulate the conditions the pellets would encounter upon re-entering Earth#39;s atmosphere. In its testing, the particles burn with an apparent magnitude of –1, which should ensure they#39;re clearly visible in the night sky, even in the polluted skyline of a metropolis like Tokyo.这家公司已经在实验室里测试了源粒子,使用了一个真空房间和高温气体来模拟小球进入地球大气层的情况。在测试中,粒子燃烧时可以达到-1的视星等,足以在夜晚的天空中清晰看到,即使在东京这样污染严重的城市里。Their speed should also make them easy to appreciate. ;Our shooting star travels slower and longer across the sky than a natural shooting star,; ALE Co. explains on its website. ;This makes it possible for more people to enjoy the spectacle for a longer period of time.;它们的速度也有利于人们观赏。ALE Co在他们的网站上解释说:“我们的流星比天然流星速度要慢,在天空中划过的时间更长。更多的人可以在更长时间里欣赏到这一奇观。”Of course, a lot of this marketing is just that for now – at least, until the company launches its first shooting-star-laden prototype. It#39;s intending to do that in the latter half of next year, and hopefully by 2018 we#39;ll start to see just how effective human-created meteorites really are.当然,目前还只是营销造势,至少我们在等待这家公司发射第一颗载流星卫星。他们已经计划在明年下半年发射,所以我们有望在2018年之前看到真正的人造流星雨。If things go well, who knows? We#39;re calling it: Tokyo 2020#39;s opening ceremony is not one to miss.如果一切顺利推进的话,谁知道呢?让我们拭目以待:2020年东京奥运会的开幕式不容错过。 /201605/445611

These are the first images of the prototype humanoid robot Vladimir Putin hopes will conquer the moon for Russia.这些就是被普京寄予厚望、将代表俄罗斯征月球的人形机器人的首批原型照片。The #39;cyber cosmonaut#39; will be sent to the International Space Station ahead of tackling more ambitious tasks on the lunar landscape.这位“俄罗斯网络宇航员”将被送往国际空间站,之后还将完成更加雄心勃勃的登月计划。Pictures show the robot walking, lifting heavy weights, using power tools, performing press-ups and even driving with Russian experts hoping it will one day be able to help build a base on the moon.图片显示,这个机器人能行走、举重、使用电动工具、做俯卧撑,甚至还能开车。俄罗斯专家希望他未来能够帮忙建立月球基地。Putin#39;s deputy premier Dmitry Rogozin said: #39;This thing can work without a space suit, live not only in a crew vehicle, but even outside it. Its name is Fedor.#39;俄罗斯副总理罗戈津称:“这个机器人叫做费多尔,他不穿宇航也可以工作,且不仅能在太空舱中生存,甚至在舱外也行。”He claimed the war in Syria had shown Russia the importance of robots in difficult environments, and promised Fedor would make its space debut in five years.罗戈津声称,叙利亚战争已向俄罗斯表明机器人在恶劣环境中的重要性,并承诺费多尔将在5年内亮相太空。Putin has also instructed his space chiefs to make a first landing on the moon within 15 years.普京还命令俄罗斯宇航局负责人在15年内实现费多尔首次登月。A key task for Fedor will be to #39;assist in construction and use of bases#39; on the moon and potentially other planets, said its Russian designers FPI.俄罗斯设计团队FPI表示,费多尔的关键任务将是“协助建设和使用月球以及其他潜在行星上的基地”。The robot can #39;crawl, stand up after falling down, take and leave driver#39;s seat in a car, use tools and operate in a regular building#39;.机器人费多尔可以“攀爬、跌倒后自行站立、进出车辆驾驶位,同时还能够利用一些工具并在一些普通建筑中完成一些操作任务”。Fedor stands 6ft tall, weighs between 106-160 kg depending on extra equipment, and can lift up to 20 kg of cargo.费多尔高6英尺(约1.8米),体重在106-160公斤之间,具体取决于额外配备的设备,可以举起20公斤重的货物。#39;During space walking missions and on other planets, astronauts will rely on robots,#39; said Sergei Khurs, head of the project and director of the National Centre for Technology Development and Basic Robotics.俄罗斯国家机器人技术发展中心负责人、项目主管Sergei Khurs表示,“在太空行走或在其他星球期间,宇航员将依赖机器人完成任务。”#39;Their capabilities are equal to those of humans, and in some ways even exceed them.#39;“他们的能力和人类不相上下,在某些方面甚至超越了人类。”Vladimir Solntsev, general director of Russian rocket-making corporation Energia, said: #39;Our involvement in the Fedor-based space robot project will bring us to the next level in the development of robotic technologies.#39;俄罗斯“能源”火箭制造公司董事长弗拉基米尔.索恩采夫说:“太空机器人项目的工作让我们的机器人研发技术提升至全新水平。”Alexander Grebenshchikov, director of the TSNIImash laboratory of space robotics, said: #39;Every hour of work of cosmonauts on space walks costs from million to million (USD). #39;TSNIImash太空机器人实验室负责人Alexander Grebenshchikov说:“俄罗斯宇航员在太空中行走一小时的成本为200万至400万美元。”#39;The use of robots for routine operations in the future will also spare additional time of the crew for leisure or for the fulfillment of other important tasks.#39;“在未来利用机器人进行日常操作将为宇航员节省出时间多休息,或者完成其他重要任务。” /201612/482389
