简介:

  公元618年,在华夏历史上占有最重要的地位的唐帝国建立。帝国建立不久,唐高祖李渊的次子——秦王李世民发动玄武门之变,诛杀同胞兄弟,如愿坐上皇帝宝座。为了向父亲展现孝道,唐高宗在长安城东北方向主持修建大明宫,以作太上皇避暑的离宫。公元664年,雄壮巍峨的大明宫落成,它占地五千多亩,相当于五百个足球场大小。从唐太宗开始,这座帝国至高无上的权力中心,在222年的岁月里见证了唐王朝的起伏兴衰,贞观之治、开元盛世,是大唐最值得称道的荣耀顶点,而安史之乱、甘露之变、黄巢起义、宦官专权、藩镇割据则接二连三在帝国的肌体上留下永远无法愈合的血型伤疤。
  战火和尘埃带走了幻灭盛景,而今的人们只能从半埋泥土中的断井残垣遥想纵隔千年的盛世繁华……

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.
