刚看到寻正文章（ http://blog.sciencenet.cn/home.php?mod=spaceuid=460310do=blogid=559478 ）谈到南加大枪击案受害者的宝马车，里面提到买宝马车的两个特点，一是招摇、二是费油。 宝马车这两点在美国应该算是人所共知的，早几个月刚刚成为能源部长朱棣文受到攻击的一个“靶点”。 朱棣文就任美国能源部长之后，能源部扶植了很多“替代能源”的项目，而这些“国家重点 项目 ”去年以来纷纷破产（最著名的Solyndra太阳能电池公司破产案只是其中之一）。美国国会就此举行了听证会，听证会上朱棣文称赞了通用汽车公司生产的 Chevy Volt电动汽车（这种车的销量远不如预期），于是被问道，他自己是不是也开一辆这种电动汽车。朱棣文回答道，“no, I don’t own a car at the moment. ”（“不，我现在没车”）。 朱棣文现在确实不开车，因为他作为政府阁员，出于安全原因每天由别人接送。不过，随后他太太的车被人查了出来，是一辆2002年的宝马325i，耗油量是每加仑21英里，远远 劣 于2002年车型各类轿车的平均值（每加仑29英里）。所以，朱棣文虽然号召节能减排之类，他自己的家庭并不是这方面的模范（ http://dailycaller.com/2012/03/09/energy-sec-chu-doesnt-own-car-but-his-wife-drives-bmw-gas-guzzler/ ）。 顺便提一下，美国汽油价格今年前三个月节节攀升，所以朱棣文不断地被人要求澄清他在就任能源部长之前曾说过的一句话——希望美国的油价和欧洲一样贵： "Somehow we have to figure out how to boost the price of gasoline to the levels in Europe," Mr. Chu, who directs the Lawrence Berkeley National Laboratory in California, said in an interview with The Wall Street Journal in September. 【翻译：“我们总得设法让（美国的）汽油价格达到欧洲的水平，”朱棣文（位于加利福尼亚的劳伦斯伯克利国家实验室的主任）在（2008年）9月《华尔街日报》的采访中说。】 美国现在的汽油价格大致是每升1.0美元，而德国现在是每升2.2美元（原因在于高昂的税收）。上个月，朱棣文表示，他不再坚持上述看法（ http://www.bloomberg.com/news/2012-03-14/steven-chu-s-epiphany-on-gas-prices-the-ticker.html ）。 这件事情再次说明，搞政治远远不像搞物理那样容易坚持integrity和consistence。
本来写了一长篇，丢了，重写没心情了，简单写写。 标题是抄徐磊的。 08年的时候朱到我们学校来领一个奖，顺便给了三场报告，一场讲变暖，一场讲单分子，还有一场给本科生谈理想谈人生。负责发奖的是我老板，哈哈。。。所以我也混迹在其中听报告。在最后一场之前，老板突然有事要离开5分钟，让我去陪一下朱博士，于是有了这个“亲密接触”。我就抓紧时间问，你研究方向换这么多，得诺奖的时候是原子物理，现在做生物物理，我之前学高分子的时候还读过你高分子物理的paper，你换这么多方向干嘛？他说，其实严格来讲我只做过两个方向，高分子物理属于搂草打兔子，不是专门做的，我也从来不自称是高分子物理学家，尽管有人这么叫我。他又问了我的研究方向，我介绍完了之后他问，what's new？我答，I am an engineer. I do not invent things. I optimize them.他点点头，不置可否。 谈人生好多都是老生常谈，比如考大学没考上好学校（只去了Rochester），比如博士学位只拿了一个（另外两个兄弟都是双博士），等等。新料也有点，比如说博士毕业以后开始做faculty，但是刚上班，就有系里元老建议停薪留职去别的地方学习一下，于是就去了Bell Lab，后来在Bell Lab觉得挺好，就决定不回学校了，于是辞职。其实李开复当年离开CMU去Apple，也是这个过程。。。 更牛的新料是当年从Bell Lab回学校，说是大家都觉得他冷冻原子能得奖，所以各个学校纷纷挖他，他最后选了给他启动资金最少的Stanford。他的理由是Stanford物理系最差（另外两个给他offer的好像是哈佛和Princeton），他去了以后可以发挥更大的影响，而去哈佛，那些牛人估计不听他的。。。从整个活动他的说法来看，他从很早的时候就有了强烈的想当官想管人的意愿，所以后来偶爸妈让他去当能源秘书，他二话不说就去了，大概也就是这个意思。 顺便说说，至少在当时，他还不认为变暖是必然的。他当时的正式说法是，我不清楚他是否会变暖，我只是担心，如果他真的变暖了，我们又啥准备工作都没做，那人类不就挂了么？ 应读者要求删了两句话，嗯，你懂的。
朱棣文2009年哈佛大学演讲：未来并非在劫难逃 朱棣文（Steven Chu，1948年2月28日－）， 美国物理学家，生于美国圣路易斯；华人血统，祖籍中国江苏太仓，曾获得诺贝尔物理学奖（1997年）。现任美国能源部部长。 1970年，获罗彻斯特大学数学学士和物理学学士。 1976年，获加州大学伯克利分校物理学博士。 1987年，任斯坦福大学物理学教授，是该校第一位华裔教授。 1993年，当选美国国家科学院院士。 1997年，获诺贝尔物理学奖。 2004年，任劳伦斯·伯克利国家实验室主任，是首位掌管这个美国能源部下属国家实验室的亚裔人士。 2009年，出任奥巴马政府能源部长。 【正文】 Madam President Faust, members of the Harvard Corporation and the Board of Overseers, faculty, family, friends, and, most importantly, today's graduates, 尊敬的Faust校长，哈佛集团的各位成员，监管理事会的各位理事，各位老师，各位家长，各位朋友，以及最重要的各位毕业生同学， Thank you for letting me share this wonderful day with you. 感谢你们，让我有机会同你们一起分享这个美妙的日子。 I am not sure I can live up to the high standards of Harvard Commencement speakers. Last year, J.K. Rowling, the billionaire novelist, who started as a classics student, graced this podium. The year before, Bill Gates, the mega-billionaire philanthropist and computer nerd stood here. Today, sadly, you have me. I am not a billionaire, but at least I am a nerd. 我不太肯定，自己够得上哈佛大学毕业典礼演讲人这样的殊荣。去年登上这个讲台的是，英国亿万身家的小说家J.K. Rowling女士，她最早是一个古典文学的学生。前年站在这里的是比尔•盖茨先生，他是一个超级富翁、一个慈善家和电脑高手。今年很遗憾，你们的演讲人是我，虽然我不是很有钱，但是至少我也算一个高手。 I am grateful to receive an honorary degree from Harvard, an honor that means more to me than you might care to imagine. You see, I was the academic black sheep of my family. My older brother has an M.D./Ph.D. from MIT and Harvard while my younger brother has a law degree from Harvard. When I was awarded a Nobel Prize, I thought my mother would be pleased. Not so. When I called her on the morning of the announcement, she replied, "That's nice, but when are you going to visit me next." Now, as the last brother with a degree from Harvard, maybe, at last, she will be satisfied. 我很感激哈佛大学给我荣誉学位，这对我很重要，也许比你们会想到的还要重要。要知道，在学术上，我是我们家的不肖之子。我的哥哥在麻省理工学院得到医学博士，在哈佛大学得到哲学博士；我的弟弟在哈佛大学得到一个法律学位。我本人得到诺贝尔奖的时候，我想我的妈妈会高兴。但是，我错了。消息公布的那天早上，我给她打电话，她听了只说："这是好消息，不过我想知道，你下次什么时候来看我？"如今在我们兄弟当中，我最终也拿到了哈佛学位，我想这一次，她会感到满意。 Another difficulty with giving a Harvard commencement address is that some of you may disapprove of the fact that I have borrowed material from previous speeches. I ask that you forgive me for two reasons. 在哈佛大学毕业典礼上发表演讲，还有一个难处，那就是你们中有些人可能有意见，不喜欢我重复前人演讲中说过的话。我要求你们谅解我，因为两个理由。 First, in order to have impact, it is important to deliver the same message more than once. In science, it is important to be the first person to make a discovery, but it is even more important to be the last person to make that discovery. 首先，为了产生影响力，很重要的方法就是重复传递同样的信息。在科学中，第一个发现者是重要的，但是在得到公认前，最后一个将这个发现重复做出来的人也许更重要。 Second, authors who borrow from others are following in the footsteps of the best. Ralph Waldo Emerson, who graduated from Harvard at the age of 18, noted "All my best thoughts were stolen by the ancients." Picasso declared "Good artists borrow. Great artists steal." Why should commencement speakers be held to a higher standard? 其次，一个借鉴他人的作者，正走在一条前人开辟的最佳道路上。哈佛大学毕业生、诗人爱默生曾经写下："古人把我最好的一些思想都偷走了。"画家毕加索宣称"优秀的艺术家借鉴，伟大的艺术家偷窃。"那么为什么毕业典礼的演说者，就不适用同样的标准呢？ I also want to point out the irony of speaking to graduates of an institution that would have rejected me, had I the chutzpah to apply. I am married to "Dean Jean," the former dean of admissions at Stanford. She assures me that she would have rejected me, if given the chance. When I showed her a draft of this speech, she objected strongly to my use of the word "rejected." She never rejected applicants; her letters stated that "we are unable to offer you admission." I have difficulty understanding the difference. After all, deans of admissions of highly selective schools are in reality, "deans of rejection." Clearly, I have a lot to learn about marketing. 我还要指出一点，向哈佛毕业生发表演说，对我来说是有讽刺意味的，因为如果当年我斗胆向哈佛大学递交入学申请，一定会被拒绝。我的妻子Jean当过斯坦福大学的招生主任，她向我保证，如果当年我申请斯坦福大学，她会拒绝我。我把这篇演讲的草稿给她过目，她强烈反对我使用"拒绝"这个词，她从来不拒绝任何申请者。在拒绝信中，她总是写："我们无法提供你入学机会。"我分不清两者到底有何差别。在我看来，那些大热门学校的招生主任与其称为"准许你入学的主任"，还不如称为"拒绝你入学的主任"。很显然，我需要好好学学怎么来推销自己。 My address will follow the classical sonata form of commencement addresses. The first movement, just presented, were light-hearted remarks. This next movement consists of unsolicited advice, which is rarely valued, seldom remembered, never followed. As Oscar Wilde said, "The only thing to do with good advice is to pass it on. It is never of any use to oneself." So, here comes the advice. First, every time you celebrate an achievement, be thankful to those who made it possible. Thank your parents and friends who supported you, thank your professors who were inspirational, and especially thank the other professors whose less-than-brilliant lectures forced you to teach yourself. Going forward, the ability to teach yourself is the hallmark of a great liberal arts education and will be the key to your success. To your fellow students who have added immeasurably to your education during those late night discussions, hug them. Also, of course, thank Harvard. Should you forget, there's an alumni association to remind you. Second, in your future life, cultivate a generous spirit. In all negotiations, don't bargain for the last, little advantage. Leave the change on the table. In your collaborations, always remember that "credit" is not a conserved quantity. In a successful collaboration, everybody gets 90 percent of the credit. 毕业典礼演讲都遵循古典奏鸣曲的结构，我的演讲也不例外。刚才是第一乐章----轻快的闲谈。接下来的第二乐章是送上门的忠告。这样的忠告很少被重视，几乎注定被忘记，永远不会被实践。但是，就像王尔德说的："对于忠告，你所能做的，就是把它送给别人，因为它对你没有任何用处。"所以，下面就是我的忠告。第一，取得成就的时候，不要忘记前人。要感谢你的父母和支持你的朋友，要感谢那些启发过你的教授，尤其要感谢那些上不好课的教授，因为他们迫使你自学。从长远看，自学能力是优秀的文理教育中必不可少的，将成为你成功的关键。你还要去拥抱你的同学，感谢他们同你进行过的许多次彻夜长谈，这为你的教育带来了无法衡量的价值。当然，你还要感谢哈佛大学。不过即使你忘了这一点，校友会也会来提醒你。第二，在你们未来的人生中，做一个慷慨大方的人。在任何谈判中，都把最后一点点利益留给对方。不要把桌上的钱都拿走。在合作中，要牢记荣誉不是一个守恒的量。成功合作的任何一方，都应获得全部荣誉的90%。 Jimmy Stewart, as Elwood P. Dowd in the movie "Harvey" got it exactly right. He said: "Years ago my mother used to say to me, 'In this world, Elwood, you must be ... she always used to call me Elwood ... in this world, Elwood, you must be oh so smart or oh so pleasant.'" Well, for years I was smart. ... I recommend pleasant. You may quote me on that. 电影《Harvey》中，Jimmy Stewart扮演的角色Elwood P. Dowd，就完全理解这一点。他说："多年前，母亲曾经对我说，'Elwood，活在这个世界上，你要么做一个聪明人，要么做一个好人。'"我做聪明人，已经做了好多年了。......但是，我推荐你们做好人。你们可以引用我这句话。 My third piece of advice is as follows: As you begin this new stage of your lives, follow your passion. If you don't have a passion, don't be satisfied until you find one. Life is too short to go through it without caring deeply about something. When I was your age, I was incredibly single-minded in my goal to be a physicist. After college, I spent eight years as a graduate student and postdoc at Berkeley, and then nine years at Bell Labs. During that my time, my central focus and professional joy was physics. 我的第三个忠告是，当你开始生活的新阶段时，请跟随你的爱好。如果你没有爱好，就去找，找不到就不罢休。生命太短暂，如果想有所成，你必须对某样东西倾注你的深情。我在你们这个年龄，是超级的一根筋，我的目标就是非成为物理学家不可。本科毕业后，我在加州大学伯克利分校又待了8年，读完了研究生，做完了博士后，然后去贝尔实验室待了9年。在这些年中，我关注的中心和职业上的全部乐趣，都来自物理学。 Here is my final piece of advice. Pursuing a personal passion is important, but it should not be your only goal. When you are old and gray, and look back on your life, you will want to be proud of what you have done. The source of that pride won't be the things you have acquired or the recognition you have received. It will be the lives you have touched and the difference you have made. 我还有最后一个忠告，就是说兴趣爱好固然重要，但是你不应该只考虑兴趣爱好。当你白发苍苍、垂垂老矣、回首人生时，你需要为自己做过的事感到自豪。你的物质生活和得到的承认，都不会产生自豪。只有那些你出手相助、被你改变过的人和事，才会让你产生自豪。 After nine years at Bell labs, I decided to leave that warm, cozy ivory tower for what I considered to be the "real world," a university. Bell Labs, to quote what was said about Mary Poppins, was "practically perfect in every way," but I wanted to leave behind something more than scientific articles. I wanted to teach and give birth to my own set of scientific children. 在贝尔实验室待了9年后，我决定离开这个温暖舒适的象牙塔，走进我眼中的"真实世界"----大学。我对贝尔实验室的看法，就像别人形容电影Mary Poppins的话，"实际上完美无缺"。但是，我想为世界留下更多的东西，不只是科学论文。我要去教书，培育我自己在科学上的后代。 Ted Geballe, a friend and distinguished colleague of mine at Stanford, who also went from Berkeley to Bell Labs to Stanford years earlier, described our motives best: 我在斯坦福大学有一个好友兼杰出同事Ted Geballe。他也是从伯克利分校去了贝尔实验室，几年前又离开贝尔实验室去了斯坦福大学。他对我们的动机做出了最佳描述： "The best part of working at a university is the students. They come in fresh, enthusiastic, open to ideas, unscarred by the battles of life. They don't realize it, but they're the recipients of the best our society can offer. If a mind is ever free to be creative, that's the time. They come in believing textbooks are authoritative, but eventually they figure out that textbooks and professors don't know everything, and then they start to think on their own. Then, I begin learning from them." "在大学工作，最大的优点就是学生。他们生机勃勃，充满热情，思想自由，还没被生活的重压改变。虽然他们自己没有意识到，但是他们是这个社会中你能找到的最佳受众。如果生命中曾经有过思想自由和充满创造力的时期，那么那个时期就是你在读大学。进校时，学生们对课本上的一字一句毫不怀疑，渐渐地，他们发现课本和教授并不是无所不知的，于是他们开始独立思考。从那时起，就是我开始向他们学习了。" My students, post doctoral fellows, and the young researchers who worked with me at Bell Labs, Stanford, and Berkeley have been extraordinary. Over 30 former group members are now professors, many at the best research institutions in the world, including Harvard. I have learned much from them. Even now, in rare moments on weekends, the remaining members of my biophysics group meet with me in the ether world of cyberspace. 我教过的学生、带过的博士后、合作过的年轻同事，都非常优秀。他们中有30多人，现在已经是教授了。他们所在的研究机构有不少是全世界第一流的，其中就包括哈佛大学。我从他们身上学到了很多东西。即使现在，我偶尔还会周末上网，向现在还从事生物物理学研究的学生请教。 I began teaching with the idea of giving back; I received more than I gave. This brings me to the final movement of this speech. It begins with a story about an extraordinary scientific discovery and a new dilemma that it poses. It's a call to arms and about making a difference. 我怀着回报社会的想法，开始了教学生涯。我的一生中，得到的多于我付出的，所以我要回报社会。这就引出了这次演讲的最后一个乐章。首先我要讲一个了不起的科学发现，以及由此带来的新挑战。它是一个战斗的号令，到了做出改变的时候了。 In the last several decades, our climate has been changing. Climate change is not new: the Earth went through six ice ages in the past 600,000 years. However, recent measurements show that the climate has begun to change rapidly. The size of the North Polar Ice Cap in the month of September is only half the size it was a mere 50 years ago. The sea level which been rising since direct measurements began in 1870 at a rate that is now five times faster than it was at the beginning of recorded measurements. Here's the remarkable scientific discovery. For the first time in human history, science is now making predictions of how our actions will affect the world 50 and 100 years from now. These changes are due to an increase in carbon dioxide put into the atmosphere since the beginning of the Industrial Revolution. The Earth has warmed up by roughly 0.8 degrees Celsius since the beginning of the Revolution. There is already approximately a 1 degree rise built into the system, even if we stop all greenhouse gas emissions today. Why? It will take decades to warm up the deep oceans before the temperature reaches a new equilibrium. 过去几十年中，我们的气候一直在发生变化。气候变化并不是现在才有的，过去60万年中就发生了6次冰河期。但是，现在的测量表明气候变化加速了。北极冰盖在9月份的大小，只相当于50年前的一半。1870年起，人们开始测量海平面上升的速度，现在的速度是那时的5倍。一个重大的科学发现就这样产生了。科学第一次在人类历史上，预测出我们的行为对50~100年后的世界有何影响。这些变化的原因是，从工业革命开始，人类排放到大气中的二氧化碳增加 了。这使得地球的平均气温上升了0.8摄氏度。即使我们立刻停止所有温室气体的排放，气温仍然将比过去上升大约1度。因为在气温达到均衡前，海水温度的上升将持续几十年。 If the world continues on a business-as-usual path, the Intergovernmental Panel on Climate Change predicts that there is a fifty-fifty chance the temperature will exceed 5 degrees by the end of this century. This increase may not sound like much, but let me remind you that during the last ice age, the world was only 6 degrees colder. During this time, most of Canada and the United States down to Ohio and Pennsylvania were covered year round by a glacier. A world 5 degrees warmer will be very different. The change will be so rapid that many species, including Humans, will have a hard time adapting. I've been told for example, that, in a much warmer world, insects were bigger. I wonder if this thing buzzing around is a precursor. 如果全世界保持现在的经济模式不变，联合国政府间气候变化专门委员会（IPCC）预测，本世纪末将有50%的可能，气温至少上升5度。这听起来好像不多，但是让我来提醒你，上一次的冰河期，地球的气温也仅仅只下降了6度。那时，俄亥俄州和宾夕法尼亚州以北的大部分美国和加拿大的土地，都终年被冰川覆盖。气温上升5度的地球，将是一个非常不同的地球。由于变化来得太快，包括人类在内的许多生物，都将很难适应。比如，有人告诉我，在更温暖的环境中，昆虫的个头将变大。我不知道现在身旁嗡嗡叫的这只大苍蝇，是不是就是前兆。 We also face the specter of nonlinear "tipping points" that may cause much more severe changes. An example of a tipping point is the thawing of the permafrost. The permafrost contains immense amounts of frozen organic matter that have been accumulating for millennia. If the soil melts, microbes will spring to life and cause this debris to rot. The difference in biological activity below freezing and above freezing is something we are all familiar with. Frozen food remains edible for a very long time in the freezer, but once thawed, it spoils quickly. How much methane and carbon dioxide might be released from the rotting permafrost? If even a fraction of the carbon is released, it could be greater than all the greenhouse gases we have released to since the beginning of the industrial revolution. Once started, a runaway effect could occur. 我们还面临另一个幽灵，那就是非线性的"气候引爆点"，这会带来许多严重得多的变化。"气候引爆点"的一个例子就是永久冻土层的融化。永久冻土层经 过千万年的累积形成，其中包含了巨量的冻僵的有机物。如果冻土融化，微生物就将广泛繁殖，使得冻土层中的有机物快速腐烂。冷冻后的生物和冷冻前的生物，它 们在生物学特性上的差异，我们都很熟悉。在冷库中，冷冻食品在经过长时间保存后，依然可以食用。但是，一旦解冻，食品很快就腐烂了。一个腐烂的永久冻土层，将释放出多少甲烷和二氧化碳？即使只有一部分的碳被释放出来，可能也比我们从工业革命开始释放出来的所有温室气体还要多。这种事情一旦发生，局势就失控了。 The climate problem is the unintended consequence of our success. We depend on fossil energy to keep our homes warm in the winter, cool in the summer, and lit at night; we use it to travel across town and across continents. Energy is a fundamental reason for the prosperity we enjoy, and we will not surrender this prosperity. The United States has 3 percent of the world population, and yet, we consume 25 percent of the energy. By contrast, there are 1.6 billion people who don't have access to electricity. Hundreds of millions of people still cook with twigs or dung. The life we enjoy may not be within the reach of the developing world, but it is within sight, and they want what we have. 气候问题是我们的经济发展在无意中带来的后果。我们太依赖化石能源，冬天取暖，夏天制冷，夜间照明，长途旅行，环球观光。能源是经济繁荣的基础，我 们不可能放弃经济繁荣。美国人口占全世界的3%，但是我们消耗全世界25%的能源。与此形成对照，全世界还有16亿人没有电，数亿人依靠燃烧树枝和动物粪便来煮饭。发展中国家的人民享受不到我们的生活，但是他们都看在眼里，他们渴望拥有我们拥有的东西。 Here is the dilemma. How much are we willing to invest, as a world society, to mitigate the consequences of climate change that will not be realized for at least 100 years? Deeply rooted in all cultures, is the notion of generational responsibility. Parents work hard so that their children will have a better life. Climate change will affect the entire world, but our natural focus is on the welfare of our immediate families. Can we, as a world society, meet our responsibility to future generations? 这就是新的挑战。全世界作为一个整体，我们到底愿意付出多少，来缓和气候变化？这种付出至少在100年内，都不会有明显效果。代际责任深深植根于所有文化中。家长努力工作，为了让他们的孩子有更好的生活。气候变化将影响整个世界，但是我们的天性使得我们只关心个人家庭的福利。我们能不能把全世界看作一个整体？能不能为未来的人们承担起责任？ While I am worried, I am hopeful we will solve this problem. I became the director of the Lawrence Berkeley National Laboratory, in part because I wanted to enlist some of the best scientific minds to help battle against climate change. I was there only four and a half years, the shortest serving director in the 78-year history of the Lab, but when I left, a number of very exciting energy institutes at the Berkeley Lab and UC Berkeley had been established. 虽然我忧心忡忡，但是还是对未来抱乐观态度，这个问题将会得到解决。我同意出任劳伦斯-伯克利国家实验室主任，部分原因是我想招募一些世界上最好的科学家，来研究气候变化的对策。我在那里干了4年半，是这个实验室78年的历史中，任期最短的主任，但是当我离任时，在伯克利实验室和伯克利分校，一些非常激动人心的能源研究机构已经建立起来了。 I am extremely privileged to be part of the Obama administration. If there ever was a time to help steer America and the world towards a path of sustainable energy, now is the time. The message the President is delivering is not one of doom and gloom, but of optimism and opportunity. I share this optimism. The task ahead is daunting, but we can and will succeed. 能够成为奥巴马施政团队的一员，我感到极其荣幸。如果有一个时机，可以引导美国和全世界走上可持续能源的道路，那么这个时机就是现在。总统已经发出 信息，未来并非在劫难逃，而是乐观的，我们依然有机会。我也抱有这种乐观主义。我们面前的任务令人生畏，但是我们能够并且将会成功。 We know some of the answers already. There are immediate and significant savings in energy efficiency and conservation. Energy efficiency is not just low-hanging fruit; it is fruit lying on the ground. For example, we have the potential to make buildings 80 percent more efficient with investments that will pay for themselves in less than 15 years. Buildings consume 40 percent of the energy we use, and a transition to energy efficient buildings will cut our carbon emissions by one-third. 我们已经有了一些答案，可以立竿见影地节约能源和提高能源使用效率。它们不是挂在枝头的水果，而是已经成熟掉在地上了，就看我们愿不愿意捡起来。比 如，我们有办法将楼宇的耗电减少80%，增加的投资在15年内就可以收回来。楼宇的耗电占我们能源消费的40%，节能楼宇的推广将使我们二氧化碳的释放减 少三分之一。 We are revving up the remarkable American innovation machine that will be the basis of a new American prosperity. We will invent much improved methods to harness the sun, the wind, nuclear power, and capture and sequester the carbon dioxide emitted from our power plants. Advanced bio-fuels and the electrification of personal vehicles make us less dependent on foreign oil. 我们正在加速美国这座巨大的创新机器，这将是下一次美国大繁荣的基础。我们将大量投资有效利用太阳能、风能、核能的新方法，大量投资能够捕获和隔离电厂废气中的二氧化碳的方法。先进的生物燃料和电力汽车将使得我们不再那么依赖外国的石油。 In the coming decades, we will almost certainly face higher oil prices and be in a carbon-constrained economy. We have the opportunity to lead in development of a new, industrial revolution. The great hockey player, Wayne Gretzky, when asked, how he positions himself on the ice, he replied," I skate to where the puck is going to be, not where it's been." America should do the same. 在未来的几十年中，我们几乎肯定会面对更高的油价和更严厉的二氧化碳限制排放政策。这是一场新的工业革命，美国有机会充当领导者。伟大的冰上曲棍球选手Wayne Gretzky被问到，他如何在冰上跑位，回答说："我滑向球下一步的位置，而不是它现在的位置。"美国也应该这样做。 The Obama administration is laying a new foundation for a prosperous and sustainable energy future, but we don't have all of the answers. That's where you come in. In this address, I am asking you, the Harvard graduates, to join us. As our future intellectual leaders, take the time to learn more about what's at stake, and then act on that knowledge. As future scientists and engineers, I ask you to give us better technology solutions. As future economists and political scientists, I ask you to create better policy options. As future business leaders, I ask that you make sustainability an integral part of your business. 奥巴马政府正在为美国的繁荣和可持续能源，打下新的基础。但是我们无法为所有问题都找到答案。这就需要你们的参与。在本次演讲中，我请求在座各位哈佛毕业生加入我们。你们是我们未来的智力领袖，请花时间加深理解目前的危险局势，然后采取相应的行动。你们是未来的科学家和工程师，我要求你们给我们更好的技术方案。你们是未来的经济学家和政治学家，我要求你们创造更好的政策选择。你们是未来的企业家，我要求你们将可持续发展作为你们业务中不可分割的一部分。 Finally, as humanists, I ask that you speak to our common humanity. One of the cruelest ironies about climate change is that the ones who will be hurt the most are the most innocent: the worlds poorest and those yet to be born. 最后，你们是人道主义者，我要求你们为了人道主义说话。气候变化带来的最残酷的讽刺之一，就是最受伤害的人，恰恰就是最无辜的人----那些世界上最穷的人们和那些还没有出生的人。 The coda to this last movement is borrowed from two humanists. 这个最后乐章的完结部是引用两个人道主义者的话。 The first quote is from Martin Luther King. He spoke on ending the war in Vietnam in 1967, but his message seems so fitting for today's climate crisis: 第一段引语来自马丁•路德•金。这是1967年他对越南战争结束的评论，但是看上去非常适合用来评论今天的气候危机。 "This call for a worldwide fellowship that lifts neighborly concern beyond one's tribe, race, class, and nation is in reality a call for an all-embracing and unconditional love for all mankind. This oft misunderstood, this oft misinterpreted concept, so readily dismissed by the Nietzsches of the world as a weak and cowardly force, has now become an absolute necessity for the survival of man ... We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late." "我呼吁全世界的人们团结一心，抛弃种族、肤色、阶级、国籍的隔阂；我呼吁包罗一切、无条件的对全人类的爱。你会因此遭受误解和误读，信奉尼采哲学的世人会认定你是一个软弱和胆怯的懦夫。但是，这是人类存在下去的绝对必需。......我的朋友，眼前的事实就是，明天就是今天。此刻，我们面临最紧急的情况。在变幻莫测的生活和历史之中，有一样东西叫做悔之晚矣。" The final message is from William Faulkner. On December 10th, 1950, his Nobel Prize banquet speech was about the role of humanists in a world facing potential nuclear holocaust. 第二段引语来自威廉•福克纳。1950年12月10月，他在诺贝尔奖获奖晚宴上发表演说，谈到了世界在核战争的阴影之下，人道主义者应该扮演什么样的角色。 "I believe that man will not merely endure: he will prevail. He is immortal, not because he alone among creatures has an inexhaustible voice, but because he has a soul, a spirit capable of compassion and sacrifice and endurance. The poet's, the writer's, duty is to write about these things. It is his privilege to help man endure by lifting his heart, by reminding him of the courage and honor and hope and pride and compassion and pity and sacrifice which have been the glory of his past." "我相信人类不仅能忍耐，而且会获胜。人类是不朽的，这不是因为万物当中仅仅他会无穷尽的呼喊，而是因为他有一个灵魂，有同情心、牺牲精神和忍耐力。诗人和作家的责任就是写这些东西。他们的特权正是通过鼓舞人类，唤起人类原有的荣耀----勇气、荣誉、希望、自尊、怜悯之心和牺牲精神，去帮助人类学会忍耐。" Graduates, you have an extraordinary role to play in our future. As you pursue your private passions, I hope you will also develop a passion and a voice to help the world in ways both large and small. Nothing will give you greater satisfaction. 各位毕业生同学，你们在我们的未来中扮演举足轻重的角色。当你们追求个人的志向时，我希望你们也会发扬奉献精神，积极发声，在大大小小各个方面帮助改进这个世界。这会给你们带来最大的满足感。 Please accept my warmest congratulations. May you prosper, may you help preserve and save our planet for your children, and all future children of the world. 最后，请接受我最热烈的祝贺。希望你们成功，也希望你们保护和拯救我们这个星球，为了你们的孩子，以及未来所有的孩子。
我转载到这里，其实是想让我们的部长们、副部长们、司长们，尤其是MOe的，学学怎么到大学演讲、怎样到大学演讲、怎样发表一份让学生获益匪浅的演讲、激发他们爱国热情和世界责任的演讲。 译者：阮一峰 Madam President Faust, members of the Harvard Corporation and the Board of Overseers, faculty, family, friends,and, most importantly, today’s graduates, 尊敬的Faust校长，哈佛集团的各位成员，监管理事会的各位理事，各位老师，各位家长，各位朋友，以及最重要的各位毕业生同学， Thank you for letting me share this wonderful day with you. 感谢你们，让我有机会同你们一起分享这个美妙的日子。 I am not sure I can live up to the high standards of Harvard Commencement speakers. Last year, J.K. Rowling, the billionaire novelist, who started as a classics student, graced this podium. The year before, Bill Gates, the mega-billionaire philanthropist and computer nerd stood here. Today, sadly, you have me. I am not wealthy, but at least I am a nerd. 我不太肯定，自己够得上哈佛大学毕业典礼演讲人这样的殊荣。去年登上这个讲台的是，英国亿万身家的小说家J.K. Rowling女士，她最早是一个古典文学的学生。前年站在这里的是比尔·盖茨先生，他是一个超级富翁、一个慈善家和电脑天才。今年很遗憾，你们的演讲人是我，虽然我不是很有钱，但是至少我是一个高手。 I am grateful to receive an honorary degree from Harvard, an honor that means more to me than you might care to imagine. You see, I was the academic black sheep of my family. My older brother has an M.D./Ph.D. from MIT and Harvard while my younger brother has a law degree from Harvard. When I was awarded a Nobel Prize, I thought my mother would be pleased. Not so. When I called her on the morning of the announcement, she replied, “That’s nice, but when are you going to visit me next.” Now, as the last brother with a degree from Harvard, maybe, at last, she will be satisfied. 我很感激哈佛大学给我荣誉学位，这对我很重要，也许比你们会想到的还要重要。要知道，在学术上，我是我们家的异类。我的哥哥在麻省理工学院得到医学博士，在哈佛大学得到哲学博士；我的弟弟在哈佛大学得到一个法律学位。我本人得到诺贝尔奖的时候，我想我的妈妈会高兴。但是，我错了。消息公布的那天早上，我给她打电话，她听了只说：“这是好消息，不过我想知道，你下次什么时候来看我？”如今在我们兄弟当中，我最终也拿到了哈佛学位，我想这一次，她会感到满意。 Another difficulty with giving a Harvard commencement address is that some of you may disapprove of the fact that I have borrowed material from previous speeches. I ask that you forgive me for two reasons. 在哈佛大学毕业典礼上发表演说，还有一个难处，那就是你们中有些人可能有意见，不喜欢我重复前人演讲中说过的话。我要求你们谅解我，因为两个理由。 First, in order to have impact, it is important to deliver the same message more than once. In science, it is important to be the first person to make a discovery, but it is even more important to be the last person to make that discovery. 首先，为了产生影响力，很重要的方法就是重复传递同样的信息。在科学中，第一个发现者是重要的，但是在得到公认前，最后一个做出这个发现的人也许更重要。 Second, authors who borrow from others are following in the footsteps of the best. Ralph Waldo Emerson, who graduated from Harvard at the age of 18, noted “All my best thoughts were stolen by the ancients.” Picasso declared “Good artists borrow. Great artists steal.” Why should commencement speakers be held to a higher standard? 其次，一个借鉴他人的作者，正走在一条前人开辟的最佳道路上。哈佛大学毕业生、诗人爱默生曾经写下：“我最好的一些思想，都是从古人那里偷来的。”画家毕加索宣称“优秀的艺术家借鉴，伟大的艺术家偷窃。”那么为什么毕业典礼的演说者，就不适用同样的标准呢？ I also want to point out the irony of speaking to graduates of an institution that would have rejected me, had I the chutzpah to apply. I am married to “Dean Jean,” the former dean of admissions at Stanford. She assures me that she would have rejected me, if given the chance. When I showed her a draft of this speech, she objected strongly to my use of the word “rejected.” She never rejected applicants; her letters stated that “we are unable to offer you admission.” I have difficulty understanding the difference. After all, deans of admissions of highly selective schools are in reality, “deans of rejection.” Clearly, I have a lot to learn about marketing. 我还要指出一点，向哈佛毕业生发表演说，对我来说是有讽刺意味的，因为如果当年我斗胆向哈佛大学递交入学申请，一定会被拒绝。我的妻子Jean当过斯坦福大学的招生主任，她向我保证，如果当年我申请斯坦福大学，她会拒绝我。我把这篇演讲的草稿给她过目，她强烈反对我使用“拒绝”这个词，她从来不拒绝任何申请者。在拒绝信中，她总是写：“我们无法提供你入学机会。”我分不清两者到底有何差别。不过，那些大热门学校的招生主任总是很现实的，堪称“拒绝他人的主任”。很显然，我需要好好学学怎么来推销自己。 My address will follow the classical sonata form of commencement addresses. The first movement, just presented, were light-hearted remarks. This next movement consists of unsolicited advice, which is rarely valued, seldom remembered, never followed. As Oscar Wilde said, “The only thing to do with good advice is to pass it on. It is never of any use to oneself.” So, here comes the advice. First, every time you celebrate an achievement, be thankful to those who made it possible. Thank your parents and friends who supported you, thank your professors who were inspirational, and especially thank the other professors whose less-than-brilliant lectures forced you to teach yourself. Going forward, the ability to teach yourself is the hallmark of a great liberal arts education and will be the key to your success. To your fellow students who have added immeasurably to your education during those late night discussions, hug them. Also, of course, thank Harvard. Should you forget, there’s an alumni association to remind you. Second, in your future life, cultivate a generous spirit. In all negotiations, don’t bargain for the last, little advantage. Leave the change on the table. In your collaborations, always remember that “credit” is not a conserved quantity. In a successful collaboration, everybody gets 90 percent of the credit. 毕业典礼演讲都遵循古典奏鸣曲的结构，我的演讲也不例外。刚才是第一乐章——轻快的闲谈。接下来的第二乐章是送上门的忠告。这样的忠告很少有价值，几乎注定被忘记，永远不会被实践。但是，就像王尔德说的：“对于忠告，你所能做的，就是把它送给别人，因为它对你没有任何用处。”所以，下面就是我的忠告。第一，取得成就的时候，不要忘记前人。要感谢你的父母和支持你的朋友，要感谢那些启发过你的教授，尤其要感谢那些上不好课的教授，因为他们迫使你自学。从整体看，自学能力是优秀的文科教育中必不可少的，将成为你成功的关键。你还要去拥抱你的同学，感谢他们同你进行过的许多次彻夜长谈，这为你的教育带来了无法衡量的价值。当然，你还要感谢哈佛大学。不过即使你忘了这一点，校友会也会来提醒你。第二，在你们未来的人生中，做一个慷慨大方的人。在任何谈判中，都把最后一点点利益留给对方。不要把桌上的钱都拿走。在合作中，不要把荣誉留给自己。成功合作的任何一方，都应获得全部荣誉的90%。 Jimmy Stewart, as Elwood P. Dowd in the movie “Harvey” got it exactly right. He said: “Years ago my mother used to say to me, ‘In this world, Elwood, you must be … she always used to call me Elwood … in this world, Elwood, you must be oh so smart or oh so pleasant.’” Well, for years I was smart. ... I recommend pleasant. You may quote me on that. 电影《Harvey》中，Jimmy Stewart扮演的角色Elwood P. Dowd，就完全理解这一点。他说：“多年前，母亲曾经对我说，‘Elwood，活在这个世界上，你要么做一个聪明人，要么做一个好人。’”我做聪明人，已经做了好多年了。……但是，我推荐你们做好人。你们可以引用我这句话。 My third piece of advice is as follows: As you begin this new stage of your lives, follow your passion. If you don’t have a passion, don’t be satisfied until you find one. Life is too short to go through it without caring deeply about something. When I was your age, I was incredibly single-minded in my goal to be a physicist. After college, I spent eight years as a graduate student and postdoc at Berkeley, and then nine years at Bell Labs. During that my time, my central focus and professional joy was physics. 我的第三个忠告是，当你开始生活的新阶段时，请跟随你的爱好。如果你没有爱好，就去找，找不到就不罢休。生命太短暂，所以不能空手走过，你必须对某样东西倾注你的深情。我在你们这个年龄，是超级的一根筋，我的目标就是非成为物理学家不可。本科毕业后，我在加州大学伯克利分校又待了8年，读完了研究生，做完了博士后，然后去贝尔实验室待了9年。在这些年中，我关注的中心和职业上的全部乐趣，都来自物理学。 Here is my final piece of advice. Pursuing a personal passion is important, but it should not be your only goal. When you are old and gray, and look back on your life, you will want to be proud of what you have done. The source of that pride won’t be the things you have acquired or the recognition you have received. It will be the lives you have touched and the difference you have made. 我还有最后一个忠告，就是说兴趣爱好固然重要，但是你不应该只考虑兴趣爱好。当你白发苍苍、垂垂老矣、回首人生时，你需要为自己做过的事感到自豪。物质生活和你实现的占有欲，都不会产生自豪。只有那些受你影响、被你改变过的人和事，才会让你产生自豪。 After nine years at Bell labs, I decided to leave that warm, cozy ivory tower for what I considered to be the “real world,” a university. Bell Labs, to quote what was said about Mary Poppins, was “practically perfect in every way,” but I wanted to leave behind something more than scientific articles. I wanted to teach and give birth to my own set of scientific children. 在贝尔实验室待了9年后，我决定离开这个温暖舒适的象牙塔，走进我眼中的“真实世界”——大学。我对贝尔实验室的看法，可以引用Mary Poppins的话，“实际上十全十美”。但是，我想离开那种仅仅是科学论文的生活。我要去教书，培育我自己在科学上的后代。 Ted Geballe, a friend and distinguished colleague of mine at Stanford, who also went from Berkeley to Bell Labs to Stanford years earlier, described our motives best: 我在斯坦福大学有一个好友兼杰出同事Ted Geballe。他也是从伯克利分校去了贝尔实验室，几年前又离开贝尔实验室去了斯坦福大学。他对我们的动机做出了最佳描述： “The best part of working at a university is the students. They come in fresh, enthusiastic, open to ideas, unscarred by the battles of life. They don’t realize it, but they’re the recipients of the best our society can offer. If a mind is ever free to be creative, that’s the time. They come in believing textbooks are authoritative, but eventually they figure out that textbooks and professors don’t know everything, and then they start to think on their own. Then, I begin learning from them.” “在大学工作，最大的优点就是学生。他们生机勃勃，充满热情，思想自由，还没被生活的重压改变。虽然他们自己没有意识到，但是他们是这个社会中你能找到的最佳受众。如果生命中只有一段时间是思想自由和充满创造力，那么那段时间就是你在读大学。进校时，学生们对课本上的一字一句毫不怀疑，渐渐地，他们发现课本和教授并不是无所不知的，于是他们开始独立思考。从那时起，就是我开始向他们学习了。” My students, post doctoral fellows, and the young researchers who worked with me at Bell Labs, Stanford, and Berkeley have been extraordinary. Over 30 former group members are now professors, many at the best research institutions in the world, including Harvard. I have learned much from them. Even now, in rare moments on weekends, the remaining members of my biophysics group meet with me in the ether world of cyberspace. 我教过的学生、带过的博士后、合作过的年轻同事，都非常优秀。他们中有30多人，现在已经是教授了。他们所在的研究机构有不少是全世界第一流的，其中就包括哈佛大学。我从他们身上学到了很多东西。即使现在，我偶尔还会周末上网，向现在还从事生物物理学研究的学生请教。 I began teaching with the idea of giving back; I received more than I gave. This brings me to the final movement of this speech. It begins with a story about an extraordinary scientific discovery and a new dilemma that it poses. It’s a call to arms and about making a difference. 我怀着回报社会的想法，开始了教学生涯。我的一生中，得到的多于我付出的，所以我要回报社会。这就引出了这次演讲的最后一个乐章。首先我要讲一个了不起的科学发现，以及由此带来的新挑战。它是一个战斗的号令，到了做出改变的时候了。 In the last several decades, our climate has been changing. Climate change is not new: the Earth went through six ice ages in the past 600,000 years. However, recent measurements show that the climate has begun to change rapidly. The size of the North Polar Ice Cap in the month of September is only half the size it was a mere 50 years ago. The sea level which been rising since direct measurements began in 1870 at a rate that is now five times faster than it was at the beginning of recorded measurements. Here’s the remarkable scientific discovery. For the first time in human history, science is now making predictions of how our actions will affect the world 50 and 100 years from now. These changes are due to an increase in carbon dioxide put into the atmosphere since the beginning of the Industrial Revolution. The Earth has warmed up by roughly 0.8 degrees Celsius since the beginning of the Revolution. There is already approximately a 1 degree rise built into the system, even if we stop all greenhouse gas emissions today. Why? It will take decades to warm up the deep oceans before the temperature reaches a new equilibrium. 过去几十年中，我们的气候一直在发生变化。气候变化并不是现在才有的，过去60万年中就发生了6次冰河期。但是，现在的测量表明气候变化加速了。北极冰盖在9月份的大小，只相当于50年前的一半。1870年起，人们开始测量海平面上升的速度，现在的速度是那时的5倍。一个重大的科学发现就这样产生了。科学第一次在人类历史上，预测出我们的行为对50~100年后的世界有何影响。这些变化的原因是，从工业革命开始，人类排放到大气中的二氧化碳增加了。这使得地球的平均气温上升了0.8摄氏度。即使我们立刻停止所有温室气体的排放，气温仍然将比过去上升大约1度。因为在气温达到均衡前，海水温度的上升将持续几十年。 If the world continues on a business-as-usual path, the Intergovernmental Panel on Climate Change predicts that there is a fifty-fifty chance the temperature will exceed 5 degrees by the end of this century. This increase may not sound like much, but let me remind you that during the last ice age, the world was only 6 degrees colder. During this time, most of Canada and the United States down to Ohio and Pennsylvania were covered year round by a glacier. A world 5 degrees warmer will be very different. The change will be so rapid that many species, including Humans, will have a hard time adapting. I’ve been told for example, that, in a much warmer world, insects were bigger. I wonder if this thing buzzing around is a precursor. 如果全世界保持现在的经济模式不变，联合国政府间气候变化专门委员会（IPCC）预测，本世纪末将有50%的可能，气温至少上升5度。这听起来好像不多，但是让我来提醒你，上一次的冰河期，地球的气温也仅仅只下降了6度。那时，俄亥俄州和费城以下的大部分美国和加拿大的土地，都终年被冰川覆盖。气温上升5度的地球，将是一个非常不同的地球。由于变化来得太快，包括人类在内的许多生物，都将很难适应。比如，有人告诉我，在更温暖的环境中，昆虫的个头将变大。我不知道现在身旁嗡嗡叫的这只大苍蝇，是不是就是前兆。 We also face the specter of nonlinear “tipping points” that may cause much more severe changes. An example of a tipping point is the thawing of the permafrost. The permafrost contains immense amounts of frozen organic matter that have been accumulating for millennia. If the soil melts, microbes will spring to life and cause this debris to rot. The difference in biological activity below freezing and above freezing is something we are all familiar with. Frozen food remains edible for a very long time in the freezer, but once thawed, it spoils quickly. How much methane and carbon dioxide might be released from the rotting permafrost? If even a fraction of the carbon is released, it could be greater than all the greenhouse gases we have released to since the beginning of the industrial revolution. Once started, a runaway effect could occur. 我们还面临另一个幽灵，那就是非线性的“气候引爆点”，这会带来许多严重得多的变化。“气候引爆点”的一个例子就是永久冻土层的融化。永久冻土层经过千万年的累积形成，其中包含了巨量的冻僵的有机物。如果冻土融化，微生物就将广泛繁殖，使得冻土层中的有机物快速腐烂。冷冻后的生物和冷冻前的生物，它们在生物学特性上的差异，我们都很熟悉。在冷库中，冷冻食品在经过长时间保存后，依然可以食用。但是，一旦解冻，食品很快就腐烂了。一个腐烂的永久冻土层，将释放出多少甲烷和二氧化碳？即使只有一部分的碳被释放出来，可能也比我们从工业革命开始释放出来的所有温室气体还要多。这种事情一旦发生，局势就失控了。 The climate problem is the unintended consequence of our success. We depend on fossil energy to keep our homes warm in the winter, cool in the summer, and lit at night; we use it to travel across town and across continents. Energy is a fundamental reason for the prosperity we enjoy, and we will not surrender this prosperity. The United States has 3 percent of the world population, and yet, we consume 25 percent of the energy. By contrast, there are 1.6 billion people who don’t have access to electricity. Hundreds of millions of people still cook with twigs or dung. The life we enjoy may not be within the reach of the developing world, but it is within sight, and they want what we have. 气候问题是我们的经济发展在无意中带来的后果。我们太依赖化石能源，冬天取暖，夏天制冷，夜间照明，长途旅行，环球观光。能源是经济繁荣的基础，我们不可能放弃经济繁荣。美国人口占全世界的3%，但是我们消耗全世界25%的能源。与此形成对照，全世界还有16亿人没有电，数亿人依靠燃烧树枝和动物粪便来煮饭。发展中国家的人民享受不到我们的生活，但是他们都看在眼里，他们渴望拥有我们拥有的东西。 Here is the dilemma. How much are we willing to invest, as a world society, to mitigate the consequences of climate change that will not be realized for at least 100 years? Deeply rooted in all cultures, is the notion of generational responsibility. Parents work hard so that their children will have a better life. Climate change will affect the entire world, but our natural focus is on the welfare of our immediate families. Can we, as a world society, meet our responsibility to future generations? 这就是新的挑战。全世界作为一个整体，我们到底愿意付出多少，来缓和气候变化？这种变化在100年前，根本没人想到过。代际责任深深植根于所有文化中。家长努力工作，为了让他们的孩子有更好的生活。气候变化将影响整个世界，但是我们的天性使得我们只关心个人家庭的福利。我们能不能把全世界看作一个整体？能不能为未来的人们承担起责任？ While I am worried, I am hopeful we will solve this problem. I became the director of the Lawrence Berkeley National Laboratory, in part because I wanted to enlist some of the best scientific minds to help battle against climate change. I was there only four and a half years, the shortest serving director in the 78-year history of the Lab, but when I left, a number of very exciting energy institutes at the Berkeley Lab and UC Berkeley had been established. 虽然我忧心忡忡，但是还是对未来抱乐观态度，这个问题将会得到解决。我同意出任劳伦斯·伯克利国家实验室主任，部分原因是我想招募一些世界上最好的科学家，来研究气候变化的对策。我在那里干了4年半，是这个实验室78年的历史中，任期最短的主任，但是当我离任时，在伯克利实验室和伯克利分校，一些非常激动人心的能源研究机构已经建立起来了。 I am extremely privileged to be part of the Obama administration. If there ever was a time to help steer America and the world towards a path of sustainable energy, now is the time. The message the President is delivering is not one of doom and gloom, but of optimism and opportunity. I share this optimism. The task ahead is daunting, but we can and will succeed. 能够成为奥巴马施政团队的一员，我感到极其荣幸。如果有一个时机，可以引导美国和全世界走上可持续能源的道路，那么这个时机就是现在。总统已经发出信息，未来并非在劫难逃，而是乐观的，我们依然有机会。我也抱有这种乐观主义。我们面前的任务令人生畏，但是我们能够并且将会成功。 We know some of the answers already. There are immediate and significant savings in energy efficiency and conservation. Energy efficiency is not just low-hanging fruit; it is fruit lying on the ground. For example, we have the potential to make buildings 80 percent more efficient with investments that will pay for themselves in less than 15 years. Buildings consume 40 percent of the energy we use, and a transition to energy efficient buildings will cut our carbon emissions by one-third. 我们已经有了一些答案，可以立竿见影地节约能源和提高能源使用效率。它们不是挂在枝头的水果，而是已经成熟掉在地上了，就看我们愿不愿意捡起来。比如，我们有办法将楼宇的耗电减少80%，增加的投资在15年内就可以收回来。楼宇的耗电占我们能源消费的40%，节能楼宇的推广将使我们二氧化碳的释放减少三分之一。 We are revving up the remarkable American innovation machine that will be the basis of a new American prosperity. We will invent much improved methods to harness the sun, the wind, nuclear power, and capture and sequester the carbon dioxide emitted from our power plants. Advanced bio-fuels and the electrification of personal vehicles make us less dependent on foreign oil. 我们正在加速美国这座巨大的创新机器，这将是下一次美国大繁荣的基础。我们将大量投资有效利用太阳能、风能、核能的新方法，大量投资能够捕获和隔离电厂废气中的二氧化碳的方法。先进的生物燃料和电力汽车将使得我们不再那么依赖外国的石油。 In the coming decades, we will almost certainly face higher oil prices and be in a carbon-constrained economy. We have the opportunity to lead in development of a new, industrial revolution. The great hockey player, Wayne Gretzky, when asked, how he positions himself on the ice, he replied,“ I skate to where the puck is going to be, not where it’s been.” America should do the same. 在未来的几十年中，我们几乎肯定会面对更高的油价和更严厉的二氧化碳排放政策。这是一场新的工业革命，美国有机会充当领导者。伟大的冰球选手Wayne Gretzky被问到，他如何在冰上跑位，回答说：“我滑向球下一步的位置，而不是它现在的位置。”美国也应该这样做。 The Obama administration is laying a new foundation for a prosperous and sustainable energy future, but we don’t have all of the answers. That’s where you come in. In this address, I am asking you, the Harvard graduates, to join us. As our future intellectual leaders, take the time to learn more about what’s at stake, and then act on that knowledge. As future scientists and engineers, I ask you to give us better technology solutions. As future economists and political scientists, I ask you to create better policy options. As future business leaders, I ask that you make sustainability an integral part of your business. 奥巴马政府正在为美国的繁荣和可持续能源，打下新的基础。但是我们还有很多不知道的地方。这就需要你们的参与。在本次演讲中，我请求在座各位哈佛毕业生加入我们。你们是我们未来的智力领袖，请花时间加深理解目前的危险局势，然后采取相应的行动。你们是未来的科学家和工程师，我要求你们给我们更好的技术方案。你们是未来的经济学家和政治学家，我要求你们创造更好的政策选择。你们是未来的企业家，我要求你们将可持续发展作为你们业务中不可分割的一部分。 Finally, as humanists, I ask that you speak to our common humanity. One of the cruelest ironies about climate change is that the ones who will be hurt the most are the most innocent: the worlds poorest and those yet to be born. 最后，你们是人道主义者，我要求你们为了人道主义说话。气候变化带来的最残酷的讽刺之一，就是最受伤害的人，恰恰就是最无辜的人——那些世界上最穷的人们和那些还没有出生的人。 The coda to this last movement is borrowed from two humanists. 这个最后乐章的完结部是引用两个人道主义者的话。 The first quote is from Martin Luther King. He spoke on ending the war in Vietnam in 1967, but his message seems so fitting for today’s climate crisis: 第一段引语来自马丁·路德·金。这是1967年他对越南战争结束的评论，但是看上去非常适合用来评论今天的气候危机。 “This call for a worldwide fellowship that lifts neighborly concern beyond one’s tribe, race, class, and nation is in reality a call for an all-embracing and unconditional love for all mankind. This oft misunderstood, this oft misinterpreted concept, so readily dismissed by the Nietzsches of the world as a weak and cowardly force, has now become an absolute necessity for the survival of man … We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late.” “我呼吁全世界的人们团结一心，抛弃种族、肤色、阶级、国籍的隔阂；我呼吁包罗一切、无条件的对全人类的爱。你会因此遭受误解和误读，信奉尼采哲学的世人会认定你是一个软弱和胆怯的懦夫。但是，这是人类存在下去的绝对必需。……我的朋友，眼前的事实就是，明天就是今天。此刻，我们面临最紧急的情况。在变幻莫测的生活和历史之中，有一样东西叫做悔之晚矣。” The final message is from William Faulkner. On December 10th, 1950, his Nobel Prize banquet speech was about the role of humanists in a world facing potential nuclear holocaust. 第二段引语来自威廉·福克纳。1950年12月10月，他在诺贝尔奖获奖晚宴上发表演说，谈到了世界在核战争的阴影之下，人道主义者应该扮演什么样的角色。 “I believe that man will not merely endure: he will prevail. He is immortal, not because he alone among creatures has an inexhaustible voice, but because he has a soul, a spirit capable of compassion and sacrifice and endurance. The poet’s, the writer’s, duty is to write about these things. It is his privilege to help man endure by lifting his heart, by reminding him of the courage and honor and hope and pride and compassion and pity and sacrifice whih have been the glory of his past.” “我相信人类不会仅仅存在，他还将胜利。人类是不朽的，这不是因为万物当中仅仅他拥有发言权，而是因为他有一个灵魂，一种有同情心、牺牲精神和忍耐力的精神。诗人、作家的责任就是书写这种精神。他们有权力升华人类的心灵，使人类回忆起过去曾经使他无比光荣的东西——勇气、荣誉、希望、自尊、同情、怜悯和牺牲。” Graduates, you have an extraordinary role to play in our future. As you pursue your private passions, I hope you will also develop a passion and a voice to help the world in ways both large and small. Nothing will give you greater satisfaction. 各位同学，你们在我们的未来中扮演举足轻重的角色。当你们追求个人的志向时，我希望你们也会发扬奉献精神，积极发声，在大大小小各个方面帮助改进这个世界。这会给你们带来最大的满足感。 Please accept my warmest congratulations. May you prosper, may you help preserve and save our planet for your children, and all future children of the world. 最后，请接受我最热烈的祝贺。希望你们成功，也希望你们保护和拯救我们这个星球，为了你们的孩子，以及未来所有的孩子。
在“听力课堂”网站上看到了朱棣文在哈佛大学毕业典礼上的演讲,非常精彩，不仅有助于学习英语，而且还有助于以后我们的讲演。一举两得，何乐而不为？ 【演讲者简介】 朱棣文（ Steven Chu ， 1948 年 2 月 28 日－）， 美国物理学家，生于美国圣路易斯；华人血统，祖籍中国江苏太仓，曾获得诺贝尔物理学奖（ 1997 年）。现任美国能源部部长。 1970 年，获罗彻斯特大学数学学士和物理学学士。 1976 年，获加州大学伯克利分校物理学博士。 1987 年，任斯坦福大学物理学教授，是该校第一位华裔教授。 1993 年，当选美国国家科学院院士。 1997 年，获诺贝尔物理学奖。 2004 年，任劳伦斯·伯克利国家实验室主任，是首位掌管这个美国能源部下属国家实验室的亚裔人士。 2009 年，出任奥巴马政府能源部长。 Madam President Faust, members of the Harvard Corporation and the Board of Overseers, faculty, family, friends, and, most importantly, today's graduates, 尊敬的 Faust 校长，哈佛集团的各位成员，监管理事会的各位理事，各位老师，各位家长，各位朋友，以及最重要的各位毕业生同学， Thank you for letting me share this wonderful day with you. 感谢你们，让我有机会同你们一起分享这个美妙的日子。 I am not sure I can live up to the high standards of Harvard Commencement speakers. Last year, J.K. Rowling, the billionaire novelist, who started as a classics student, graced this podium. The year before, Bill Gates, the mega-billionaire philanthropist and computer nerd stood here. Today, sadly, you have me. I am not wealthy, but at least I am a nerd. 我不太肯定，自己够得上哈佛大学毕业典礼演讲人这样的殊荣。去年登上这个讲台的是，英国亿万身家的小说家 J.K. Rowling 女士，她最早是一个古典文学的学生。前年站在这里的是比尔•盖茨先生，他是一个超级富翁、一个慈善家和电脑高手。今年很遗憾，你们的演讲人是我，虽然我不是很有钱，但是至少我也算一个高手。 I am grateful to receive an honorary degree from Harvard, an honor that means more to me than you might care to imagine. You see, I was the academic black sheep of my family. My older brother has an M.D./Ph.D. from MIT and Harvard while my younger brother has a law degree from Harvard. When I was awarded a Nobel Prize, I thought my mother would be pleased. Not so. When I called her on the morning of the announcement, she replied, "That's nice, but when are you going to visit me next." Now, as the last brother with a degree from Harvard, maybe, at last, she will be satisfied. 我 很感激哈佛大学给我荣誉学位，这对我很重要，也许比你们会想到的还要重要。要知道，在学术上，我是我们家的不肖之子。我的哥哥在麻省理工学院得到医学博 士，在哈佛大学得到哲学博士；我的弟弟在哈佛大学得到一个法律学位。我本人得到诺贝尔奖的时候，我想我的妈妈会高兴。但是，我错了。消息公布的那天早上， 我给她打电话，她听了只说： " 这是好消息，不过我想知道，你下次什么时候来看我？ " 如今在我们兄弟当中，我最终也拿到了哈佛学位，我想这一次，她会感到满意。更多信息请访问： http://www.24en.com/ Another difficulty with giving a Harvard commencement address is that some of you may disapprove of the fact that I have borrowed material from previous speeches. I ask that you forgive me for two reasons. 在哈佛大学毕业典礼上发表演讲，还有一个难处，那就是你们中有些人可能有意见，不喜欢我重复前人演讲中说过的话。我要求你们谅解我，因为两个理由。 First, in order to have impact, it is important to deliver the same message more than once. In science, it is important to be the first person to make a discovery, but it is even more important to be the last person to make that discovery. 首先，为了产生影响力，很重要的方法就是重复传递同样的信息。在科学中，第一个发现者是重要的，但是在得到公认前，最后一个将这个发现重复做出来的人也许更重要。 Second, authors who borrow from others are following in the footsteps of the best. Ralph Waldo Emerson, who graduated from Harvard at the age of 18, noted "All my best thoughts were stolen by the ancients." Picasso declared "Good artists borrow. Great artists steal." Why should commencement speakers be held to a higher standard? 其次，一个借鉴他人的作者，正走在一条前人开辟的最佳道路上。哈佛大学毕业生、诗人爱默生曾经写下： " 古人把我最好的一些思想都偷走了。 " 画家毕加索宣称 " 优秀的艺术家借鉴，伟大的艺术家偷窃。 " 那么为什么毕业典礼的演说者，就不适用同样的标准呢？ I also want to point out the irony of speaking to graduates of an institution that would have rejected me, had I the chutzpah to apply. I am married to "Dean Jean," the former dean of admissions at Stanford. She assures me that she would have rejected me, if given the chance. When I showed her a draft of this speech, she objected strongly to my use of the word "rejected." She never rejected applicants; her letters stated that "we are unable to offer you admission." I have difficulty understanding the difference. After all, deans of admissions of highly selective schools are in reality, "deans of rejection." Clearly, I have a lot to learn about marketing. 我还要指出一点，向哈佛毕业生发表演说，对我来说是有讽刺意味的，因为如果当年我斗胆向哈佛大学递交入学申请，一定会被拒绝。我的妻子 Jean 当过斯坦福大学的招生主任，她向我保证，如果当年我申请斯坦福大学，她会拒绝我。我把这篇演讲的草稿给她过目，她强烈反对我使用 " 拒绝 " 这个词，她从来不拒绝任何申请者。在拒绝信中，她总是写： " 我们无法提供你入学机会。 " 我分不清两者到底有何差别。在我看来，那些大热门学校的招生主任与其称为 " 准许你入学的主任 " ，还不如称为 " 拒绝你入学的主任 " 。很显然，我需要好好学学怎么来推销自己。 My address will follow the classical sonata form of commencement addresses. The first movement, just presented, were light-hearted remarks. This next movement consists of unsolicited advice, which is rarely valued, seldom remembered, never followed. As Oscar Wilde said, "The only thing to do with good advice is to pass it on. It is never of any use to oneself." So, here comes the advice. First, every time you celebrate an achievement, be thankful to those who made it possible. Thank your parents and friends who supported you, thank your professors who were inspirational, and especially thank the other professors whose less-than-brilliant lectures forced you to teach yourself. Going forward, the ability to teach yourself is the hallmark of a great liberal arts education and will be the key to your success. To your fellow students who have added immeasurably to your education during those late night discussions, hug them. Also, of course, thank Harvard. Should you forget, there's an alumni association to remind you. Second, in your future life, cultivate a generous spirit. In all negotiations, don't bargain for the last, little advantage. Leave the change on the table. In your collaborations, always remember that "credit" is not a conserved quantity. In a successful collaboration, everybody gets 90 percent of the credit. 毕业典礼演讲都遵循古典奏鸣曲的结构，我的演讲也不例外。刚才是第一乐章 ---- 轻快的闲谈。接下来的第二乐章是送上门的忠告。这样的忠告很少被重视，几乎注定被忘记，永远不会被实践。但是，就像王尔德说的： " 对于忠告，你所能做的，就是把它送给别人，因为它对你没有任何用处。 " 所 以，下面就是我的忠告。第一，取得成就的时候，不要忘记前人。要感谢你的父母和支持你的朋友，要感谢那些启发过你的教授，尤其要感谢那些上不好课的教授， 因为他们迫使你自学。从长远看，自学能力是优秀的文理教育中必不可少的，将成为你成功的关键。你还要去拥抱你的同学，感谢他们同你进行过的许多次彻夜长 谈，这为你的教育带来了无法衡量的价值。当然，你还要感谢哈佛大学。不过即使你忘了这一点，校友会也会来提醒你。第二，在你们未来的人生中，做一个慷慨大 方的人。在任何谈判中，都把最后一点点利益留给对方。不要把桌上的钱都拿走。在合作中，要牢记荣誉不是一个守恒的量。成功合作的任何一方，都应获得全部荣 誉的 90% 。 Jimmy Stewart, as Elwood P. Dowd in the movie "Harvey" got it exactly right. He said: "Years ago my mother used to say to me, 'In this world, Elwood, you must be ... she always used to call me Elwood ... in this world, Elwood, you must be oh so smart or oh so pleasant.'" Well, for years I was smart. ... I recommend pleasant. You may quote me on that. 电影《 Harvey 》中， Jimmy Stewart 扮演的角色 Elwood P. Dowd ，就完全理解这一点。他说： " 多年前，母亲曾经对我说， 'Elwood ，活在这个世界上，你要么做一个聪明人，要么做一个好人。 '" 我做聪明人，已经做了好多年了。 ...... 但是，我推荐你们做好人。你们可以引用我这句话。 My third piece of advice is as follows: As you begin this new stage of your lives, follow your passion. If you don't have a passion, don't be satisfied until you find one. Life is too short to go through it without caring deeply about something. When I was your age, I was incredibly single-minded in my goal to be a physicist. After college, I spent eight years as a graduate student and postdoc at Berkeley, and then nine years at Bell Labs. During that my time, my central focus and professional joy was physics. 我 的第三个忠告是，当你开始生活的新阶段时，请跟随你的爱好。如果你没有爱好，就去找，找不到就不罢休。生命太短暂，如果想有所成，你必须对某样东西倾注你 的深情。我在你们这个年龄，是超级的一根筋，我的目标就是非成为物理学家不可。本科毕业后，我在加州大学伯克利分校又待了 8 年，读完了研究生，做完了博士后，然后去贝尔实验室待了 9 年。在这些年中，我关注的中心和职业上的全部乐趣，都来自物理学。 Here is my final piece of advice. Pursuing a personal passion is important, but it should not be your only goal. When you are old and gray, and look back on your life, you will want to be proud of what you have done. The source of that pride won't be the things you have acquired or the recognition you have received. It will be the lives you have touched and the difference you have made. 我还有最后一个忠告，就是说兴趣爱好固然重要，但是你不应该只考虑兴趣爱好。当你白发苍苍、垂垂老矣、回首人生时，你需要为自己做过的事感到自豪。你的物质生活和得到的承认，都不会产生自豪。只有那些你出手相助、被你改变过的人和事，才会让你产生自豪。 After nine years at Bell labs, I decided to leave that warm, cozy ivory tower for what I considered to be the "real world," a university. Bell Labs, to quote what was said about Mary Poppins, was "practically perfect in every way," but I wanted to leave behind something more than scientific articles. I wanted to teach and give birth to my own set of scientific children. 在贝尔实验室待了 9 年后，我决定离开这个温暖舒适的象牙塔，走进我眼中的 " 真实世界 " ——大学。我对贝尔实验室的看法，就像别人形容电影 Mary Poppins 的话， " 实际上完美无缺 " 。但是，我想为世界留下更多的东西，不只是科学论文。我要去教书，培育我自己在科学上的后代。 Ted Geballe, a friend and distinguished colleague of mine at Stanford, who also went from Berkeley to Bell Labs to Stanford years earlier, described our motives best: 我在斯坦福大学有一个好友兼杰出同事 Ted Geballe 。他也是从伯克利分校去了贝尔实验室，几年前又离开贝尔实验室去了斯坦福大学。他对我们的动机做出了最佳描述： "The best part of working at a university is the students. They come in fresh, enthusiastic, open to ideas, unscarred by the battles of life. They don't realize it, but they're the recipients of the best our society can offer. If a mind is ever free to be creative, that's the time. They come in believing textbooks are authoritative, but eventually they figure out that textbooks and professors don't know everything, and then they start to think on their own. Then, I begin learning from them." " 在 大学工作，最大的优点就是学生。他们生机勃勃，充满热情，思想自由，还没被生活的重压改变。虽然他们自己没有意识到，但是他们是这个社会中你能找到的最佳 受众。如果生命中曾经有过思想自由和充满创造力的时期，那么那个时期就是你在读大学。进校时，学生们对课本上的一字一句毫不怀疑，渐渐地，他们发现课本和 教授并不是无所不知的，于是他们开始独立思考。从那时起，就是我开始向他们学习了。 " My students, post doctoral fellows, and the young researchers who worked with me at Bell Labs, Stanford, and Berkeley have been extraordinary. Over 30 former group members are now professors, many at the best research institutions in the world, including Harvard. I have learned much from them. Even now, in rare moments on weekends, the remaining members of my biophysics group meet with me in the ether world of cyberspace. 我教过的学生、带过的博士后、合作过的年轻同事，都非常优秀。他们中有 30 多人，现在已经是教授了。他们所在的研究机构有不少是全世界第一流的，其中就包括哈佛大学。我从他们身上学到了很多东西。即使现在，我偶尔还会周末上网，向现在还从事生物物理学研究的学生请教。 I began teaching with the idea of giving back; I received more than I gave. This brings me to the final movement of this speech. It begins with a story about an extraordinary scientific discovery and a new dilemma that it poses. It's a call to arms and about making a difference. 我怀着回报社会的想法，开始了教学生涯。我的一生中，得到的多于我付出的，所以我要回报社会。这就引出了这次演讲的最后一个乐章。首先我要讲一个了不起的科学发现，以及由此带来的新挑战。它是一个战斗的号令，到了做出改变的时候了。 In the last several decades, our climate has been changing. Climate change is not new: the Earth went through six ice ages in the past 600,000 years. However, recent measurements show that the climate has begun to change rapidly. The size of the North Polar Ice Cap in the month of September is only half the size it was a mere 50 years ago. The sea level which been rising since direct measurements began in 1870 at a rate that is now five times faster than it was at the beginning of recorded measurements. Here's the remarkable scientific discovery. For the first time in human history, science is now making predictions of how our actions will affect the world 50 and 100 years from now. These changes are due to an increase in carbon dioxide put into the atmosphere since the beginning of the Industrial Revolution. The Earth has warmed up by roughly 0.8 degrees Celsius since the beginning of the Revolution. There is already approximately a 1 degree rise built into the system, even if we stop all greenhouse gas emissions today. Why? It will take decades to warm up the deep oceans before the temperature reaches a new equilibrium. 过去几十年中，我们的气候一直在发生变化。气候变化并不是现在才有的，过去 60 万年中就发生了 6 次冰河期。但是，现在的测量表明气候变化加速了。北极冰盖在 9 月份的大小，只相当于 50 年前的一半。 1870 年起，人们开始测量海平面上升的速度，现在的速度是那时的 5 倍。一个重大的科学发现就这样产生了。科学第一次在人类历史上，预测出我们的行为对 50 — 100 年后的世界有何影响。这些变化的原因是，从工业革命开始，人类排放到大气中的二氧化碳增加 了。这使得地球的平均气温上升了 0.8 摄氏度。即使我们立刻停止所有温室气体的排放，气温仍然将比过去上升大约 1 度。因为在气温达到均衡前，海水温度的上升将持续几十年。 If the world continues on a business-as-usual path, the Intergovernmental Panel on Climate Change predicts that there is a fifty-fifty chance the temperature will exceed 5 degrees by the end of this century. This increase may not sound like much, but let me remind you that during the last ice age, the world was only 6 degrees colder. During this time, most of Canada and the United States down to Ohio and Pennsylvania were covered year round by a glacier. A world 5 degrees warmer will be very different. The change will be so rapid that many species, including Humans, will have a hard time adapting. I've been told for example, that, in a much warmer world, insects were bigger. I wonder if this thing buzzing around is a precursor. 如果全世界保持现在的经济模式不变，联合国政府间气候变化专门委员会（ IPCC ）预测，本世纪末将有 50% 的可能，气温至少上升 5 度。这听起来好像不多，但是让我来提醒你，上一次的冰河期，地球的气温也仅仅只下降了 6 度。那时，俄亥俄州和宾夕法尼亚州以北的大部分美国和加拿大的土地，都终年被冰川覆盖。气温上升 5 度的地球，将是一个非常不同的地球。由于变化来得太快，包括人类在内的许多生物，都将很难适应。比如，有人告诉我，在更温暖的环境中，昆虫的个头将变大。我不知道现在身旁嗡嗡叫的这只大苍蝇，是不是就是前兆。 We also face the specter of nonlinear "tipping points" that may cause much more severe changes. An example of a tipping point is the thawing of the permafrost. The permafrost contains immense amounts of frozen organic matter that have been accumulating for millennia. If the soil melts, microbes will spring to life and cause this debris to rot. The difference in biological activity below freezing and above freezing is something we are all familiar with. Frozen food remains edible for a very long time in the freezer, but once thawed, it spoils quickly. How much methane and carbon dioxide might be released from the rotting permafrost? If even a fraction of the carbon is released, it could be greater than all the greenhouse gases we have released to since the beginning of the industrial revolution. Once started, a runaway effect could occur. 我们还面临另一个幽灵，那就是非线性的 " 气候引爆点 " ，这会带来许多严重得多的变化。 " 气候引爆点 " 的一个例子就是永久冻土层的融化。永久冻土层经 过千万年的累积形成，其中包含了巨量的冻僵的有机物。如果冻土融化，微生物就将广泛繁殖，使得冻土层中的有机物快速腐烂。冷冻后的生物和冷冻前的生物，它 们 在生物学特性上的差异，我们都很熟悉。在冷库中，冷冻食品在经过长时间保存后，依然可以食用。但是，一旦解冻，食品很快就腐烂了。一个腐烂的永久冻土层， 将释放出多少甲烷和二氧化碳？即使只有一部分的碳被释放出来，可能也比我们从工业革命开始释放出来的所有温室气体还要多。这种事情一旦发生，局势就失控 了。 The climate problem is the unintended consequence of our success. We depend on fossil energy to keep our homes warm in the winter, cool in the summer, and lit at night; we use it to travel across town and across continents. Energy is a fundamental reason for the prosperity we enjoy, and we will not surrender this prosperity. The United States has 3 percent of the world population, and yet, we consume 25 percent of the energy. By contrast, there are 1.6 billion people who don't have access to electricity. Hundreds of millions of people still cook with twigs or dung. The life we enjoy may not be within the reach of the developing world, but it is within sight, and they want what we have. 气候问题是我们的经济发展在无意中带来的后果。我们太依赖化石能源，冬天取暖，夏天制冷，夜间照明，长途旅行，环球观光。能源是经济繁荣的基础，我 们不可能放弃经济繁荣。美国人口占全世界的 3% ，但是我们消耗全世界 25% 的能源。与此形成对照，全世界还有 16 亿人没有电，数亿人依靠燃烧树枝和动物粪便来煮饭。发展中国家的人民享受不到我们的生活，但是他们都看在眼里，他们渴望拥有我们拥有的东西。 Here is the dilemma. How much are we willing to invest, as a world society, to mitigate the consequences of climate change that will not be realized for at least 100 years? Deeply rooted in all cultures, is the notion of generational responsibility. Parents work hard so that their children will have a better life. Climate change will affect the entire world, but our natural focus is on the welfare of our immediate families. Can we, as a world society, meet our responsibility to future generations? 这就是新的挑战。全世界作为一个整体，我们到底愿意付出多少，来缓和气候变化？这种付出至少在 100 年内，都不会有明显效果。代际责任深深植根于所有文化中。家长努力工作，为了让他们的孩子有更好的生活。气候变化将影响整个世界，但是我们的天性使得我们只关心个人家庭的福利。我们能不能把全世界看作一个整体？能不能为未来的人们承担起责任？ While I am worried, I am hopeful we will solve this problem. I became the director of the Lawrence Berkeley National Laboratory, in part because I wanted to enlist some of the best scientific minds to help battle against climate change. I was there only four and a half years, the shortest serving director in the 78-year history of the Lab, but when I left, a number of very exciting energy institutes at the Berkeley Lab and UC Berkeley had been established. 虽然我忧心忡忡，但是还是对未来抱乐观态度，这个问题将会得到解决。我同意出任劳伦斯 - 伯克利国家实验室主任，部分原因是我想招募一些世界上最好的科学家，来研究气候变化的对策。我在那里干了 4 年半，是这个实验室 78 年的历史中，任期最短的主任，但是当我离任时，在伯克利实验室和伯克利分校，一些非常激动人心的能源研究机构已经建立起来了。 I am extremely privileged to be part of the Obama administration. If there ever was a time to help steer America and the world towards a path of sustainable energy, now is the time. The message the President is delivering is not one of doom and gloom, but of optimism and opportunity. I share this optimism. The task ahead is daunting, but we can and will succeed. 能够成为奥巴马施政团队的一员，我感到极其荣幸。如果有一个时机，可以引导美国和全世界走上可持续能源的道路，那么这个时机就是现在。总统已经发出 信息，未来并非在劫难逃，而是乐观的，我们依然有机会。我也抱有这种乐观主义。我们面前的任务令人生畏，但是我们能够并且将会成功。 We know some of the answers already. There are immediate and significant savings in energy efficiency and conservation. Energy efficiency is not just low-hanging fruit; it is fruit lying on the ground. For example, we have the potential to make buildings 80 percent more efficient with investments that will pay for themselves in less than 15 years. Buildings consume 40 percent of the energy we use, and a transition to energy efficient buildings will cut our carbon emissions by one-third. 我们已经有了一些答案，可以立竿见影地节约能源和提高能源使用效率。它们不是挂在枝头的水果，而是已经成熟掉在地上了，就看我们愿不愿意捡起来。比 如，我们有办法将楼宇的耗电减少 80% ，增加的投资在 15 年内就可以收回来。楼宇的耗电占我们能源消费的 40% ，节能楼宇的推广将使我们二氧化碳的释放减 少三分之一。 We are revving up the remarkable American innovation machine that will be the basis of a new American prosperity. We will invent much improved methods to harness the sun, the wind, nuclear power, and capture and sequester the carbon dioxide emitted from our power plants. Advanced bio-fuels and the electrification of personal vehicles make us less dependent on foreign oil. 我们正在加速美国这座巨大的创新机器，这将是下一次美国大繁荣的基础。我们将大量投资有效利用太阳能、风能、核能的新方法，大量投资能够捕获和隔离电厂废气中的二氧化碳的方法。先进的生物燃料和电力汽车将使得我们不再那么依赖外国的石油。 In the coming decades, we will almost certainly face higher oil prices and be in a carbon-constrained economy. We have the opportunity to lead in development of a new, industrial revolution. The great hockey player, Wayne Gretzky, when asked, how he positions himself on the ice, he replied," I skate to where the puck is going to be, not where it's been." America should do the same. 在未来的几十年中，我们几乎肯定会面对更高的油价和更严厉的二氧化碳限制排放政策。这是一场新的工业革命，美国有机会充当领导者。伟大的冰上曲棍球选手 Wayne Gretzky 被问到，他如何在冰上跑位，回答说： " 我滑向球下一步的位置，而不是它现在的位置。 " 美国也应该这样做。 The Obama administration is laying a new foundation for a prosperous and sustainable energy future, but we don't have all of the answers. That's where you come in. In this address, I am asking you, the Harvard graduates, to join us. As our future intellectual leaders, take the time to learn more about what's at stake, and then act on that knowledge. As future scientists and engineers, I ask you to give us better technology solutions. As future economists and political scientists, I ask you to create better policy options. As future business leaders, I ask that you make sustainability an integral part of your business. 奥 巴马政府正在为美国的繁荣和可持续能源，打下新的基础。但是我们无法为所有问题都找到答案。这就需要你们的参与。在本次演讲中，我请求在座各位哈佛毕业生 加入我们。你们是我们未来的智力领袖，请花时间加深理解目前的危险局势，然后采取相应的行动。你们是未来的科学家和工程师，我要求你们给我们更好的技术方 案。你们是未来的经济学家和政治学家，我要求你们创造更好的政策选择。你们是未来的企业家，我要求你们将可持续发展作为你们业务中不可分割的一部分。 Finally, as humanists, I ask that you speak to our common humanity. One of the cruelest ironies about climate change is that the ones who will be hurt the most are the most innocent: the worlds poorest and those yet to be born. 最后，你们是人道主义者，我要求你们为了人道主义说话。气候变化带来的最残酷的讽刺之一，就是最受伤害的人，恰恰就是最无辜的人 ---- 那些世界上最穷的人们和那些还没有出生的人。 The coda to this last movement is borrowed from two humanists. 这个最后乐章的完结部是引用两个人道主义者的话。 The first quote is from Martin Luther King. He spoke on ending the war in Vietnam in 1967, but his message seems so fitting for today's climate crisis: 第一段引语来自马丁•路德•金。这是 1967 年他对越南战争结束的评论，但是看上去非常适合用来评论今天的气候危机。 "This call for a worldwide fellowship that lifts neighborly concern beyond one's tribe, race, class, and nation is in reality a call for an all-embracing and unconditional love for all mankind. This oft misunderstood, this oft misinterpreted concept, so readily dismissed by the Nietzsches of the world as a weak and cowardly force, has now become an absolute necessity for the survival of man ... We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late." " 我呼吁全世界的人们团结一心，抛弃种族、肤色、阶级、国籍的隔阂；我呼吁包罗一切、无条件的对全人类的爱。你会因此遭受误解和误读，信奉尼采哲学的世人会认定你是一个软弱和胆怯的懦夫。但是，这是人类存在下去的绝对必需。 ...... 我的朋友，眼前的事实就是，明天就是今天。此刻，我们面临最紧急的情况。在变幻莫测的生活和历史之中，有一样东西叫做悔之晚矣。 " The final message is from William Faulkner. On December 10th, 1950, his Nobel Prize banquet speech was about the role of humanists in a world facing potential nuclear holocaust. 第二段引语来自威廉•福克纳。 1950 年 12 月 10 月，他在诺贝尔奖获奖晚宴上发表演说，谈到了世界在核战争的阴影之下，人道主义者应该扮演什么样的角色。 "I believe that man will not merely endure: he will prevail. He is immortal, not because he alone among creatures has an inexhaustible voice, but because he has a soul, a spirit capable of compassion and sacrifice and endurance. The poet's, the writer's, duty is to write about these things. It is his privilege to help man endure by lifting his heart, by reminding him of the courage and honor and hope and pride and compassion and pity and sacrifice which have been the glory of his past." " 我相信人类不仅能忍耐，而且会获胜。人类是不朽的，这不是因为万物当中仅仅他会无穷尽的呼喊，而是因为他有一个灵魂，有同情心、牺牲精神和忍耐力。诗人和作家的责任就是写这些东西。他们的特权正是通过鼓舞人类，唤起人类原有的荣耀 ---- 勇气、荣誉、希望、自尊、怜悯之心和牺牲精神，去帮助人类学会忍耐。 " Graduates, you have an extraordinary role to play in our future. As you pursue your private passions, I hope you will also develop a passion and a voice to help the world in ways both large and small. Nothing will give you greater satisfaction. 各位毕业生同学，你们在我们的未来中扮演举足轻重的角色。当你们追求个人的志向时，我希望你们也会发扬奉献精神，积极发声，在大大小小各个方面帮助改进这个世界。这会给你们带来最大的满足感。 Please accept my warmest congratulations. May you prosper, may you help preserve and save our planet for your children, and all future children of the world. 最后，请接受我最热烈的祝贺。希望你们成功，也希望你们保护和拯救我们这个星球，为了你们的孩子，以及未来所有的孩子。 音频下载：http://ishare.iask.sina.com.cn/f/5830331.html
美国能源部长、诺奖获得者朱棣文先生清华演讲的中译本，可在多个地址下载，也可在我的博客朱棣文清华演讲现场花絮 http://www.sciencenet.cn/m/user_content.aspx?id=244001 ） 中获得。 这个中译本，应该是经过严格的一校二校连三校的官方版吧，应该是一个完蛋（类比完人而来）吧。然而，从这个鸡蛋里还是可以挑出骨头来。 1）第57张片子：美国伊利诺伊的 非受精 、非灌溉试验田比玉米地每英亩多产15倍的乙醇。 非受精试验田，是啥意思？ 朱棣文演讲稿中的原文为：Non-fertilized。zl yang教授指出：Non-fertilized＝非受精？这引起了我的兴趣。我查了谷歌金山词霸没有找到这个词。改换为查fertilized，得到已受精的。于是Non-fertilized，可以理解为非受精。但我以为Non-fertilized这里指的是未施化肥的的意思。各位以为然否？ 2）最后一张片子：我的朋友们，我们现在面临这样一个事实，明天既是今天。我们现在面临着强烈的紧迫性。在此展开生活和历史的难题时，有这样一件事就是太晚了。马丁路德金。 A 且不管这个翻译的好坏 ，其中的既是错别字吧，当为即。 B 马丁路德金中间应该有标点符号吧，当为：马丁路德金。 C 再谈翻译。那个官方版的翻译，你认为读得通吗？读得懂吗？ 原文为 ：We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late. Martin Luther King, 1967 那个经常为Science写中国报道的高手郝炘女士，琢磨出一个翻译：朋友们，我们现在面临这样一个事实，明天 就是今天。我们 面临着此时此刻的强烈紧迫性。 面对这个不断发展的生命和历史的难题，再不行动就太晚了。 （ http://www.sciencenet.cn/m/user_content.aspx?id=243930 ）。我认为，郝女士的翻译，比美国官方版的翻译要好。 我呢，也斗胆试着翻译，如下： 同志们朋友们： 我们必须认识到，明天就是我们的今天。 我们现在的形势异常严峻。 生命的苦难和历史的苦难，正在展开； 我们必须未雨绸缪，否则就悔之晚矣！ 大家看，朱棣文借用 马丁路德金当年用于 反对美国越战的这个演讲，用于说全球气候变化，真是再恰当不过了。 最后来点评论：我同意郝炘女士所说美国能源部英译中的水平还不行。从朱棣文演讲的中译本存在的问题来看 ，美国高官的秘书班子或秀才们，似乎还不是非常的professionalism，也还不够太认真。 professionalism和认真是两个很要命的东西。咱 中国人熟知一句话：世界上怕就怕认真二字。
2009年7月15日上午，美国能源部部长朱棣文在清华大学发表主题为《应对能源与气候变化的挑战》的演讲，他表示，美国的目标是在八到十年之内开始实现碳捕捉和封存技术的商业化应用。 链接地址如下： 英文新闻的链接： http://www.energy.gov/news2009/7642.htm 中文新闻的链接： http://www.chinanews.com.cn/gn/news/2009/07-15/1776100.shtml 中文PPT（PDF版）下载链接： 应对能源和气候的挑战:两个国家的故事 英文PPT（PDF版）下载链接： Meeting the energy and climate challenge: A Tale of Two Countries 凤凰网视频链接： 新闻报道+演讲+中文翻译
郝炘 2009年7月16日 (修改版) 虽然没能在现场听朱棣文的清华演讲，光是看演讲的幻灯片也能感受到他的激情。中国科学界的领导人有几位有这样的口才，能用有说服力的数据、而不是靠玩弄没有意思的统计数字（比如发表了多少SCI论文）说话的？！ 不过美国能源部英译中的水平还不行，没能把 马丁 路德金充满号召力的语气传达出来。不知道国内有没有出版过中文版的金演说集，我试着把结尾那段引言翻译一下吧。 原文： We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late. 美国能源部的翻译： 我的朋友们，我们现在面临这样一个事实，明天 既是今天。我们 现在面临着强烈的紧迫性。在此展开生活和历史的难题时，有这样一件事就是太晚了 。 我的翻译： 我的 朋友们，我们现在面临这样一个事实，明天 就是今天。我们 面临着此时此刻的强烈紧迫性。 面对这个不断发展的生命和历史的难题，再不行动就太晚了。 这是金1967年做的一个反对美国继续越战的讲演中的一段话，对气候变化同样适用。
美国媒体报道奥巴马的新环境班子已见分晓，诺贝尔奖获得者 朱 棣文被提名为能源部长。看来奥巴马真用the best and the brightest. 2007 年在美国科学促进会的年会上，曾听过 朱 棣文的大会演讲： The energy problem and what we can do to solve it. 他说，美国人均天然能源消耗是每年3500 亿 焦耳，人们（包括物理学家）对这个数字没有概念。现代社会到来之前，财富一般按有多少牲畜、佣人来计算。 如果把人均 天然能源消耗折算成维持一个干活的人生存所需能量的话，美国的能耗水平相当于 把人均 1000个佣人给他干活，欧洲人平均每人有500个佣人，中国的人均能耗相当于每人有100个佣人，所以现代化的生活水平比过去顾几十个佣人的有钱人家高。但是如果要进一步提高发展中国家人民的生活水平，需要将能源的使用效率最大化，也需要新的能源。 朱棣文当了Lawrence Berkeley Lab 主任后，这个国家实验室的研究重点转移到可再生能源上，尤其各种提高太阳能利用率的研究。 朱 棣文说他在贝尔实验室长大，贝尔实验室出了 15 位诺贝尔奖获得者。该实验室成功的秘诀是只雇年轻人：研究生毕业或刚做完博士后的年轻人，也有个别拿到助理教授职位的人，给这些年轻人自由、宽松的工作环境，有充分的资金，不受官僚们的干预。 可以在网上看讲演的录像： http://www.aaas.org/meetings/Annual_Meeting/2007_San_Fran/lectures/chu/chu.ram 最好是和PPT 片子一起看: http://www.aaas.org/meetings/Annual_Meeting/2007_San_Fran/lectures/chu/chu.ppt
