大城无小事城市真英雄2021

2014年4月16日，追踪世越号航线，对至今尚未查明的沉没原因进行了科学的分析与记录。对于事故发生时间的陈述，各自不同的记录以及消失的航迹，以乘客的采访和目击者的证词及专家咨询等为基础，重新组织了那天大海上发生的事情。
　　耗资9亿韩元，经过科学验证及坚实的CG还原，再现沉 船过程。航线再构成花费六个月，在长达四年的时间里缜密调查，从物理学博士的咨询开始，首次公开世越号幸存者的另一种证词和资料等客观证据。
　　并非单纯的“提出质疑”，而是以“事实”为依据，完全不同的新的世越号纪录片诞生。由执导《백년전쟁 1부》（《百年战争第1部》）、《프레이저 보고서 1부-누가 한국 경제를 성장시켰는가》（《Fraser Report第一部-谁让韩国经济增长了》）通过犀利的目光和执着的采访被称为“疯狂的金导演”的金智永担任导演。

Changes to the bacteria that live inside all of us are responsible for increasing the number of people with allergies, suggests new research. 　　In this episode of Horizon, the show investigates this claim by conducting a unique experiment with two allergic families in order to find out just what it is in the modern world that is to blame. With a raft of mini cameras, GPS units an...

　　Largely unchanged for more than a century, the projection of photochemical film faces an uncertain future in the digital age. The practice of handing and projecting film is in danger of being lost and the role of film projectionist is nearing extinction. THE DYING OF THE LIGHT explores at the history and craft of motion picture presentation through the lives and stories of the last generation of career projectionists. By turns humorous and melancholic, their candid reflections on life in the booth reveal a world that has largely gone unnoticed and is now at an end. The result is a loving tribute to the art and romance of the movies-and to the unseen people who brought the light to our screens.

　　《法医密档》以一个个经典案例为载体，从法医的视角讲述案件侦破的过程，将刑事科学技术与刑侦紧密结合。例如死亡时间的概念，《法医密档》中就会对死亡时间做详细的介绍。法医是通过什么方式，能够精准的推算出死者的死亡时间，进而为刑侦人员提供可靠的破案依据。除了“死亡时间”之外，还有如何确定“死者身份”、如何通过一滴干枯的血迹寻找凶手等等。节目在破解案件的同时，也在传递法医“为死者代言，为生者谋权”的职业精神。

　　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.
