The economic and social forces shaping Dayton, Ohio, a once booming city that now struggles to recover in the post-recession economy.

简　　介: 　　追根溯源：哲学和黑客帝国– 学者、哲学家和理论家解构黑客三部曲 　　难题：小说背后的科学 – 真实的矩阵是否可信？相关技术的调查 　　The Roots of The Matrix”这张碟中包含两个各长一小时的重要节目：“Return To Source: Philosophy %26amp; The Matrix”和“The Hard Problem: The Science Behind The Fiction”。前者从哲学的角度分析了The Matrix系列电影的众多含义，多位哲学家、大学教授和作者悉数登场，不断引经据典，探讨三部曲电影的哲学意义，他们谈到的很多话题在我们以前的一些讨论中也或多或少提到过，所以听来甚是亲切，它也为两位哲学家所做的随片评论做出了更多的补充，绝对是Matrix迷们不可错过的节目；后者则从科学的角度探讨了人工智能、机器人、人类思维研究等方面的问题，多位人工智能科学家、生物科学家、科幻小说作家和网络游戏制作者畅谈他们对科技和AI发展的看法以及在发展过程中遇到的难题。这张碟还有一个同样精彩的彩蛋，彩蛋中的7个小片段也分别是Return To Source和The Hard Problem的补充，比如“The Writer's Journey”一书的作者Christopher Vogler伴随The Matrix的电影片段来讲述英雄故事的写作模式，哲学家分析剧中人物名字和车牌号的含义，圣杯和Merovingian的传说，机器是上帝而Smith是耶稣的说法，科学家演示讲解分子重组机器人和纳米科技，等等，这些小片段都给我们带来更多来自影片内外的不同体验。

Brian takes an audience, with the help of celebrity guests, on a journey into the wonderful universe of The Doctor, in a specially recorded programme from the lecture theatre of the Royal Institution of Great Britain. 　　Brian reveals the science behind the spectacle and explains the physics that allows Doctor Who to travel through space and time. Fun, but filled with real science, it’s a special night for Who fans as well anyone with a thirst for understanding. 　　Brian is in the unique position of knowing The Doctor’s universe inside out as well as the reality behind the drama. When the TARDIS travels through time and space, Brian understands the physics involved. And when it comes to life on other planets, Brian knows the real science that could prove extra-terrestrial life might just really exist in our galaxy.

Sleep has long been regarded as nothing more than a way to charge our batteries. But what if it can control our weight, allow us to make memories, and help us to fight off diseases like Alzheimer’s? We travel the world to investigate how revolutionary new technology has revealed the sleeping brain as an energetic and purposeful machine.

本纪录片通过展现了夏天的常见现象，从自然现象：海浪、闪电、萤火虫飞舞，到人类的一些活动，比如冲浪、吃冰淇淋，还有打棒球等等。通过这些常见现象，这些人类活动，揭示了他们背后的科学原理。闪电是如何形成的？当一个人被闪电击中后，他能否活下来？冲浪到底是怎么回事？当你吃冰淇淋时，你的大脑会不会感受到一阵尖锐的疼痛？为什么在夏天，我们总是受蚊虫骚扰？而夏季末萤火虫带来的盛宴又是为了什么？还有美国人民最爱的运动——棒球——背后的科学原理是什么？观看本纪录片，来寻找答案吧！

本片讲述的是冬天的科学——前半部分，针对人类在冬天面临的一系列问题：暴风雪、人容易滑倒、汽车发生侧翻、极寒天气下人体如何应对等，探讨了这些问题背后的科学原理、影响和解决方案。此外还回答了一些有趣的问题，例如是否存在两片形状完全相同的雪花，舌头被冻在铁门上如何应对，如何高效快速除冰等。随后展示了滑雪、雪橇等雪上运动的风采。影片后半部分讲述的是动物在冬天的御寒手段。着重对比了北极熊和松鼠的冬眠状况，并提出松鼠的冬眠状况对于人类器官移植具有启发意义。

物理学家Jim Al-Khalili游历叙利亚、伊朗、突尼斯、西班牙等国，向您展示8世纪-14世纪伊斯兰世界的巨大科学进步。共3集。 　　Information 　　Episode 1: The Language of Science. 　　Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. Its legacy is tangible, with terms like algebra, algorithm and alkali being Arabic in origin and at the very heart of modern science. For Baghdad-born Al-Khalili this is also a personal journey and he uncovers a diverse, outward-looking culture, fascinated by learning and obsessed with science. 　　Episode 2: The Empire of Reason. 　　Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. He travels to Syria to discover how, a thousand years ago, the astronomer and mathematician Al-Biruni estimated the size of the earth to within a few hundred miles of the correct figure. In Cairo, he tells the story of the physicist Ibn al-Haytham, who helped establish the science of optics. 　　Episode 3: The Power of Doubt. 　　Physicist Jim Al-Khalili concludes his investigation into the relationship between science and Islam. He shows how the scientific revolution that took place in 16th and 17th century Europe had its roots in the world of medieval Islam. He travels across Iran, Syria and Egypt to discover the astronomical advances made by Islamic scholars through their obsession with accurate measurement. He then visits Italy to see how those ideas permeated into the West and helped shape the works of Copernicus.
