SDcamps•演辩营全国英语演讲与辩论赛
For ten days during Christmas of 1995, Hubble stared into the abyss – seeking whatever light it could glean from the darkness. 在1995年圣诞节的前后十天里,哈勃望远镜凝视着深邃的太空–寻找着它可以从黑暗中收集到的任何光亮。 And it was total darkness. 但它却彻彻底底是黑暗的。 Fellow astronomers didn’t know if he’d see much of anything. 后来...
At a time when Washington is consumed with the daily debates of our Nation, 此时,华盛顿每天还充斥着对我们国家的辩论, I was proud that Congress came together overwhelmingly to reaffirm our Nation’s commitment to expanding the frontiers of knowledge. 我很自豪国会压倒性一致地重申了我们国家对扩展知识视野的承诺。 NASA’s greatest discoveries teach us many,...
My fellow Americans, 我的美国同胞们, This week, in the company of astronauts, I was honored to sign the NASA Transition Authorization Act right into law. 本周,在宇航员们的陪伴下,我很荣幸签署NASA过渡授权法案成为法律。 With this legislation, we renew our national commitment to NASA’S mission of exploration and discovery. 在这一法律框架下,我们重申对NASA探...
As I should have shown this earlier, it will not be humans who witness the end point of the sun; it will be creatures as different from us as we are from bacteria. 我前面曾指出的一点是，人类将不能见证太阳的最后生命时刻，那时的生物与我们的差别将和我们现在与细菌间的差别一样悬殊。 When Einstein died in 1955, one striking tribute to his global status was this cartoon by H...
We need not just campaigning physicists, but we need biologists, computer experts and environmentalists as well. 我们不仅需要参加竞选的物理学家，还需要有生物学家，计算机专家和环境保护者们共同参与。 And I think academics and independent entrepreneurs have a special obligation because they have more freedom than those in government service, or company employees subject ...
In fact, some years ago, Bill Joy wrote an article expressing tremendous concern about robots taking us over, etc. 事实上在几年前，比尔乔伊在一篇文章中表达了对机器人将取代我们的极大关注，等等。 I don’t go along with all that, but it’s interesting that he had a simple solution. 我并不完全同意他的观点，但让人感兴趣的是他给出了一个简单的解决方案。 It wa...
The planet became an intense emitter of radio waves — the total output from all TV and cell phones and radar transmissions. 地球开始发射出强烈的电磁波 – 其来源是所有的电视，手机和雷达信号传输。 And something else happened. Metallic objects — albeit very small ones, a few tons at most — escaped into orbit around the Earth. 另外还有一些景象出...
On a still bigger scale, we see entire galaxies of stars. We see entire ecosystems where gas is being recycled. 在更大的范围里，我们看到恒星组成的星系。我们看到完整的生态系统，看到气体被回收利用。 And to the cosmologist, these galaxies are just the atoms, as it were, of the large-scale universe. 对于宇宙学家来说，这些星系只不过是组成大规模宇宙空间的原子。 This p...
If you take 10,000 people at random, 9,999 have something in common: their interests in business lie on or near the Earth’s surface. 如果你随机挑选出10000个人，其中的9999个人会有如下共性：他们对商业的兴趣显而易见。 The odd one out is an astronomer, and I am one of that strange breed. My talk will be in two parts. 余下的那位怪人是天文学家，而我就是这个奇特物种...
Well, let’s go back to this picture. There’s one challenge symbolized at the top, but there’s another challenge to science symbolized at the bottom. 好吧，让我们回到这张图片。在其上部有一个符号化了的科学挑战。而在其下部同样有一个符号化了的科学挑战。 You want to not only synthesize the very large and the very small, but we want to understand the very ...
