本片摄制于1949年。 为了用胶片记录下开国大典的实况，中央政府专门邀请了前苏联的摄制人员，与我们自己的摄影师一起拍摄。没想到的是，苏联人拍摄的这批胶片，却意外地毁于一场火灾。因此，中央新闻纪录电影制片厂保存的这部影片，就成了开国大典仅存的影象记录。 本片从筹备建国工作的第一次全国政治协商会议切入，全方位多视角地展示了开国大典的历史场面，具有极其珍贵的史料价值和收藏价值。
Since 2003, our top secret Top Gear test track (based just off the A281 in Surrey) has played host to all manner of glamorous metal in the hands of The Stig, celebrities in an array of afforable hatchbacks, the odd barbeque or two, and John Prescott. Here’s everything you need to know from 13 years of smoke and power - with links to all the behind the scenes footage.
Six dads gather in rural Oklahoma for a weekend fishing trip. As the men cast their rods into the river, share their catch over dinner, and swap stories beside the bonfire, we learn what has brought them to this scenic idyll: the love for their trans and LGBTQ children, their fears for their children's safety, and the urgency to fight for the ground on which they all stand. The Dads is a quiet meditation on fatherhood, brotherhood and manhood amid the changing American landscape.
The war on terror is everywhere and anywhere. In this series, we learn about the deadly terrorist attacks that almost happened or were not as deadly as planned. Each episodes explores a recently declassified terrorist scheme intended to cause mass casualties.
数千年来，它们共享海洋，但科学家们才刚刚开始了解鲨鱼和海豚之间的关ccc。新的研究让我们能够窥视这部令人难以置信的戏剧；重新定义我们认为我们所知道的关于鲨鱼的一切。他们被定型为独立的孤独者、海上连环杀手——但我们观察到他们成群结队地狩猎、学习，甚至将知识传授给鲨鱼同伴。

A sharp, witty, mind-expanding and exuberant foray into the world of logic with computer scientist Professor Dave Cliff. Following in the footsteps of the award-winning 'The Joy of Stats' and its sequel, 'Tails You Win - The Science of Chance', this film takes viewers on a new rollercoaster ride through philosophy, maths, science and technology- all of which, under the bonnet, run on logic. Wielding the same wit and wisdom, animation and gleeful nerdery as its predecessors, this film journeys from Aristotle to Alice in Wonderland, sci-fi to supercomputers to tell the fascinating story of the quest for certainty and the fundamentals of sound reasoning itself. Dave Cliff, professor of computer science and engineering at Bristol University, is no abstract theoretician. 15 years ago he combined logic and a bit of maths to write one of the first computer programs to outperform humans at trading stocks and shares. Giving away the software for free, he says, was not his most logical move... With the help of 25 seven-year-olds, Professor Cliff creates, for the first time ever, a computer made entirely of children, running on nothing but logic. We also meet the world's brainiest whizz-kids, competing at the International Olympiad of Informatics in Brisbane, Australia. 'The Joy of Logic' also hails logic's all-time heroes: George Boole who moved logic beyond philosophy to mathematics Bertrand Russell, who took 360+ pages but heroically proved that 1 + 1 = 2 Kurt Godel, who brought logic to its knees by demonstrating that some truths are unprovable and Alan Turing, who, with what Cliff calls an 'almost exquisite paradox', was inspired by this huge setback to logic to conceive the computer. Ultimately, the film asks, can humans really stay ahead? Could today's generation of logical computing machines be smarter than us? What does that tell us about our own brains, and just how 'logical' we really are...?
