- March 16, 2014
In the second episode of Cosmos: Possible Worlds season 1, titled "Some of the Things that Molecules Do," host Neil deGrasse Tyson takes us on a journey to explore the fascinating world of molecules and their incredible abilities. From the humble water molecule to the complex DNA strand, Tyson shows us how the behavior and interactions of these tiny structures are the foundation of life as we know it.
Starting off with an exploration of water, Tyson explains how this seemingly simple molecule has amazing properties that make it essential for life on Earth. We learn about its ability to form hydrogen bonds, which give water its unique properties such as surface tension, adhesion, and cohesion. We also see how water's ability to dissolve other substances is crucial for transporting nutrients throughout our bodies.
Moving on to DNA, Tyson takes us on a journey through its history and evolution. We learn about how the discovery of DNA's structure changed our understanding of genetics and paved the way for modern genetic engineering. We also see how DNA plays a crucial role in our understanding of evolution, helping us to trace our ancestry and the relationships between different species.
Throughout the episode, Tyson also emphasizes the importance of molecular interactions in shaping our world. We see how the properties of molecules determine the behavior of everything from rocks to stars, and how their interactions can lead to everything from the formation of life to the destruction of civilizations. Ultimately, the episode highlights just how essential molecules are for both the creation and maintenance of our planet and everything on it.
As with all episodes of Cosmos: Possible Worlds, "Some of the Things that Molecules Do" is filled with stunning visuals and expert storytelling that bring complex scientific concepts to life. Whether you're an avid science enthusiast or simply curious about the world around us, this episode is an enlightening and engaging exploration of one of the most fundamental aspects of life on Earth.
