Ep 7. The Clean Room

The Clean Room is the seventh episode of season one of Cosmos: A Spacetime Odyssey. In this episode, host Neil deGrasse Tyson explores the idea that cleanliness is essential for scientific progress. He discusses how many of the technological advancements we take for granted today were made possible by the development of the clean room, a sterile environment where microelectronics and other advanced technologies can be developed and manufactured.

Tyson first explains the concept of cleanliness in general and how it is necessary for progress and innovation. He likens the growth of technology to the growth of a tree, pointing out how both require a healthy environment in which to grow and thrive. This sets the stage for him to delve deeper into the topic of clean rooms and their importance in the world of scientific research.

The episode features interviews with experts in the fields of microelectronics and nanotechnology, as Tyson highlights how the development of the clean room has allowed for the miniaturization of electronics and the creation of new materials that have revolutionized the world. He also explores the history of the clean room, which dates back to the invention of the transistor in the late 1940s.

Tyson discusses how the early pioneers of microelectronics, such as William Shockley and Robert Noyce, recognized the need for a clean environment in which to develop the extremely small transistors they were working on. They worked to create a sterile clean room environment that would allow them to fabricate microelectronics with the precision necessary to make breakthroughs in the field.

Throughout the episode, Tyson emphasizes the importance of attention to detail and how even the smallest particle can impact the outcome of experiments and research. This is illustrated through a series of demonstrations involving dust and lint, which show how contaminants can cause serious problems in a clean room environment.

As Tyson explains, the development of the clean room has played a crucial role in the ability of scientists to advance technology and industry. Without the clean room, we would not have the advanced microelectronics, computer chips, and other technologies that we rely on in our daily lives.

One of the highlights of the episode is the exploration of NASA's clean room, where some of the most advanced technologies in the world are developed. Tyson interviews experts who work in the clean room, giving viewers a glimpse into the world of scientific research and development.

Overall, The Clean Room is a fascinating exploration of the connection between cleanliness and scientific progress. Tyson does an excellent job of highlighting the importance of the clean room in advancing technology and industry, while also emphasizing the need for attention to detail and precision in all scientific research. This episode is a must-watch for anyone interested in the intersection of science and technology, and the role cleanliness plays in the scientific process.
