PBS Space Time Season 2018 Episode 13 Physics of Life
- April 11, 2018
PBS Space Time season 2018 episode 13 explores the intriguing and complex relationship between physics and biology in the quest to understand the origin and evolution of life on Earth. The episode, titled "Physics of Life," delves into how fundamental laws of physics play a pivotal role in shaping the biological structures and functions of living organisms.
The episode begins with an overview of the basic laws of physics, such as thermodynamics and quantum mechanics, and how they underpin the principles of life itself. From there, it explores how the properties of matter and energy serve as the building blocks of all living things, including the complex molecules and structures that form the basis of life as we know it.
The episode then delves into the origins of life, examining how the laws of physics may have played a pivotal role in the formation of the first living cells. It explores the fascinating concept of abiogenesis, or the emergence of life from non-living matter, and how it is intimately tied to a range of physical phenomena, from the cosmic chemistry of early Earth to the intricate workings of molecular biology.
As the episode moves forward, it looks at the ways in which physics and biology continue to intersect in the ongoing evolution and adaptation of life on Earth, from the intricate networks of proteins that drive cellular metabolism to the complex sensory systems that enable organisms to navigate their environment. It examines the role of genetic mutations and natural selection in shaping the evolution of species, and how these processes are ultimately governed by the laws of physics and chemistry.
One of the central themes of the episode is the idea that life is not just a product of physics, but a process that actively participates in shaping and modifying the underlying physical laws of the universe. Through examples ranging from the evolution of photosynthesis to the symbiotic relationships between different species, the episode examines how life has played an active role in shaping the composition and dynamics of the physical world around it.
Throughout the episode, expert contributors shed light on the various topics covered, ranging from physicists and biologists to astrobiologists and chemists. Their insights help to provide a rich and multifaceted understanding of the complex interplay between physics and biology in the ongoing saga of life on Earth.
Overall, "Physics of Life" offers a sweeping and fascinating exploration of the intersection between two of the most fundamental fields of scientific inquiry. With stunning visuals, insightful commentary, and a wealth of fascinating examples and case studies, the episode offers a unique and compelling perspective on the origins, evolution, and ongoing mystery of life.
