简介:

  黄河中游的三门峡湿地,是野生大天鹅重要的越冬栖息地。每年吸引一万余只越冬的大天鹅。一只雌性大天鹅“美峡”翅膀受伤,不得不永久留在越冬地。在这里,它与另一只受伤的天鹅组建家庭并孵化出了7只幼崽,这是野生大天鹅在黄河流域越冬地自然繁殖成功的首例。随后的五个月里,美峡先后失去 丈夫和一个孩子,家庭遭受巨大变故。单亲母亲困难重重。秋末,大天鹅陆续抵达黄河中游的越冬地。美峡的领地也受到了挑战。第二年春季,越冬的天鹅开始飞回北方繁殖地。面对迁徙,六个孩子又将何去何从呢?
  "A female swan Meixia, whose wings were injured and could not fly, had to stay permanently in the wintering grounds, where she and another wounded swan fell in love, then started to breed and rear their young.
  However, Meixia lost her husband and one child sequentially in five months, the single mother suffered deeply from her family lost and life bristled with difficulties for her unexpectedly. At the end of autumn, the wintering ground in the Yellow River Basin is crowded with other swans which means Meixia’s territory is facing challenge.
  Next year spring, swans are flying back to their breeding grounds. When facing migration, what will be the destiny of her six children?"

简介:

  本系列是创新的科学特备节目,共有三集。透过互动实验和各种小技巧,展现我们的大脑如何创造现实幻觉。这些令人兴奋和具有启发性的实验,能让我们一窥大脑的内部运作,而世界顶尖的专家会解释他们工作的内容及原因。我们也会在高科技实验室探索最新科学,与绝顶聪明的人物见面。三集节目的主题分别为注意力、感官(视觉和听觉)及记忆。
  EP01 注意力
  本集主题为注意力,顶尖魔术师大卫高柏飞专精於操控观众的注意力并创造令人惊叹的幻觉,科学家会运用他们对注意力的了解,创造与顶尖魔术师匹敌的幻觉。注意力的瓶颈能减少脑部刺激,甚至一只哥斯拉从你眼前走过也看不到!
  EP02 感官经验
  本节目在荷李活录影厂摄制,制片家使用声音影像创造逼真幻象。令人意外的是,人类的耳朵与眼睛时刻都在创造有关真实世界的幻象,色彩、光线、动作与深度都是由大脑建构,而这些体验其实可轻易受到操控。
  EP03 记忆
  本集节目的主题是记忆力之谜。在纽约市的街道上,以一宗骇人听闻的罪案测试观众的记忆力。记忆力能决定你是怎样的人,而细节遗失、回忆改变,令大脑形成的记忆都是假的。专家对於我们脑部的创造力和回忆力的看法,令人大吃一惊。

简介:

  Massive machines require engineering extremes.
  The massive man-made satellite, commonly known as the International Space Station, hurtling around the Earth at 27,600 km an hour, has been a temporary home for humans for the last 20 years. The biggest land vehicle on earth, a bucket excavator titled Bagger 293, that can move 240,000 cubic meters of dirt each day. Innovation has always meant building bigger, faster, taller, longer and stronger than anything that came before. We’ve seen them in dramatic visual fashion. But how do these actually work? What sets each machine apart. What big ideas drove its evolution and what limitations did this machine overcome? What forces was it built to withstand and where is the breaking point? Using CGI and expert insights, we ‘strip down’ the design of some of the world’s unique colossal machines and reveal mechanical secrets that not only made them work, but also changed the world in a big way!
  Each episode explores four incredible machines, linked thematically. From sea and space faring designs, to mega airborne, mining and industrial machines, we’ll break down what they can do as well as key inner mechanics and materials that make it all possible. Dynamic archival footage featuring; slow motion, aerials, and time-lapses get us past the ‘caution’ tape and up close and personal with these compound monsters. CGI provides breakouts and blueprints and a look at hidden mechanisms. Adding expertise of structural, mechanical, chemical and forensic engineers to help reveal what’s at stake when these colossal constructions are put work, and how all the pieces come together to make a big impact.
