Ep 3. Beyond the Elements: Indestructible
- February 10, 2021
Beyond the Elements: Indestructible is the third episode of the fiftieth season of the acclaimed documentary series NOVA. The series, which premiered in 1974, explores various scientific and technological topics.
In this particular episode, the focus is on what makes certain materials so incredibly tough and resilient. The host, David Pogue, takes viewers on a journey through the world of materials science, investigating various substances that seem almost unbreakable.
Pogue begins by setting the stage, explaining that humans have been fascinated with indestructible materials since ancient times. He mentions mythical substances like Greek fire and the Philosopher's Stone before diving into the science of the matter.
The episode is divided into several segments, each focusing on a particular category of indestructible materials. For example, Pogue explores the world of aircraft black boxes, which are engineered to survive even the most catastrophic plane crashes. He speaks with experts who explain the various technologies and materials used to create these devices, which must be able to withstand extreme temperatures, pressure, and impact.
Another segment delves into the world of super-strong adhesives. Pogue explores the chemistry behind these materials, which are used in everything from aerospace to construction. He visits a laboratory where scientists are developing new adhesives inspired by geckos, whose feet are able to stick to surfaces due to tiny hairs called setae.
In another segment, Pogue speaks with researchers who are attempting to create indestructible materials through genetically engineering organisms. He visits a lab where scientists are using bacteria to create new types of nanostructures that could one day be used to build stronger, lighter materials.
Throughout the episode, Pogue also highlights the societal impacts of these indestructible materials. He speaks with experts who explain how advanced composites and other materials are making cars safer and more fuel-efficient, and how new technologies are helping protect critical infrastructure like bridges and buildings in areas prone to earthquakes and other natural disasters.
Ultimately, Beyond the Elements: Indestructible offers a fascinating look at the cutting-edge science and engineering behind some of the toughest materials on the planet. Whether you're a science enthusiast or simply curious about the world around you, this episode is sure to delight and inform.
