简介:

  A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry. Following in the footsteps of BBC Four's previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of. Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution.
  For Hannah Fry, the joy of data is all about spotting patterns. She's Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations.
  Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia. What's the mystery link between 'marmalade' and 'One Direction'?
  The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information. It was Shannon, father of the 'bit', who singlehandedly launched the 'information age'. Meanwhile, the green lawns of Britain's National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks. It's all thanks to the brilliant technique first invented there in the 1960s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it.
  But what of the future, big data and artificial intelligence? Should we be worried by the pace of change, and what our own data could and should be used for? Ultimately, Fry concludes, data has empowered all of us. We must have machines at our side if we're to find patterns in the modern-day data deluge. But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them.

  由BBC自然历史名主持人戴维艾登堡录精采旁白,史诗般的海洋全纪录-独家拍摄的珍贵画面,让您见识海洋最恐怖与最具魅力的一面,更揭开它最隐藏的秘密。本节目带您进入令人叹为观止的美丽海洋世界,探索新的物种,造访无人所至的生态,并亲眼目睹从未在镜头前出现过的求生实录。
  本片由奥斯卡提名电影配乐大师乔治芬顿 (安娜与国王,甘地,危险关系)创作配乐,BBC交响乐团演奏。卓越的影音技术结合,将dvd带领至高质量影音新境界,值得永久推荐珍藏。
  Episode 1 蓝色星球 The Blue Planet 大部分海洋领域仍然隐身在未为人知的神秘面纱中。本集将会综观全系列,介绍海洋的不同范畴,完全揭露海洋的规模、力量与复杂性。探索海洋运作的物理与生物力量,并解释如何影响生命聚集的地理位置。
  Episode 2 幽暗深海 The Deep 在所有的海洋生态中,深海依然是最神秘莫测的地方。在黑暗的迷离世界里,动物都在捉秘藏。有许多生物都像隐了形一样,希望无声无色地避开敌人,隐藏在黑暗之中。为了得到少有的食物,掠食者拥有超大的口与牙齿,潜藏在路边,像捕鼠器般等待;猎物送上门来。
  Episode 3 远洋辽阔 Open Ocean 在广阔的大海中寻找生命的足迹,向着渺无边际的蓝色大海,四面八方伸展开去。在这海洋沙漠中,上面的阳光透不进来,下面则是黑暗深渊。无尽的大海看似荒芜一片,但令人难以置信的是,有许多最奇特的掠食者竟然聚居此处。一簇簇的大海草,为鱼类提供最佳的居所,但也令它们成为掠食者手到擒来的快餐。
  Episode 4 冰封大海 Frozen Seas 首次,我们对南、北极的严峻与艰辛作一比较。在这里,海洋每年的结冰与解冻,主宰生命的节奏。冬天的温度会急降至摄氏零下七十度,只有在春天稍有舒缓,此时阳光普照,浮游生物才会涌现,为众多生物提供养分;在短暂的休息后,寒冰又会随着秋天的风暴卷土重来……
  Episode 5 季节性海域 Seasonal Seas 随着季节的变更,本集将探究太阳能量的转变对海洋生物的影响。我们会前进到最富饶的海洋生态:温和的海洋。水是最重要的能源,巨大的海草森林为成千上万的动物提供庇护。海濑、惊惶失措的七色海葵、鱿鱼、青叶龙等等,都是居住在这个凉快且富饶的水域中的某些例子。
  Episode 6 瑰丽珊瑚海 Coral Seas 沐浴于阳光充沛的温暖清澈热带海域,让珊瑚礁成为海洋中的热带雨林,亦是海床沙漠的绿洲。种类繁多的鱼儿争奇斗艳,并在礁岩中展开弱肉强食的生存竞争。珊瑚为鱼类提供居所之余,也是充满生命力一族。这是一个关于珊瑚的故事:珊瑚礁的形成到终结,乃至于受到灾难式的摧毁……
  Episode 7 潮汐之间 Tidal Seas 潮汐涨退主宰着海洋生物,掌管了生物繁殖的地点与时间。潮汐沼泽地带更是世界上最富饶的地方,丰富的植物供养着为数众多的生物,但是生活仍是坚困。掠食者随时随地都在巡视正片沼泽,水退潮后把动物暴露出来,迫使它们不断迁徙寻找庇护,只有等到再次涨潮时,方能松一口气……
  Episode 8 多变海岸线 Coasts 潮水界限以外,可能是海洋中最具生命力的世界。涨潮不断,只有少数生物会长居于此,其他大部分生物都要由大海中返回海岸,繁殖下一代。海鸟、海龟甚至某些鱼类都会上岸产卵。海狮上岸生育,吸引杀人鲸乘浪而来,让他们成为下一餐的主食。
  Episode 9 隐忧 Deep Trouble 多年来,人类一直挖掘海洋找寻事物与丰富资源,可是我们快要失去这个珍贵宝库了。海洋抵受不了人类残酷的折磨;鱼类不断被捕捞、海洋生态受到严重威胁、经历数千年进化才成熟的珊瑚礁,往往会被盲目扫荡海床的鱼网在瞬间中摧毁……我们可以成功扭转这个局面吗?
  Episode 10 清波作浪 Making Waves 本章系列的成功要素、见证科学家与摄制队的热忱与承诺,把冒险家与大自然搏斗的实录亲身体验与感性的生物研究,一一披露眼前。清波作浪是献给所有热爱海洋研究的朋友之作品。
