Ep 2. Some of the Things That Molecules Do

In the 2nd episode of the first season of Cosmos: A Spacetime Odyssey, titled Some of the Things That Molecules Do, host Neil deGrasse Tyson takes viewers on a journey through the inner workings of the human body, exploring the ways in which molecules interact to create life.

Tyson explains how the humble water molecule, made up of just two hydrogen atoms and one oxygen atom, is the foundation of all life on Earth. He dives into the concept of molecular bonding, describing how atoms come together to form complex structures like DNA. Along the way, he explores the various chemical reactions that occur within the body to keep us alive and healthy.

Throughout the episode, Tyson uses stunning visual effects to illustrate the intricate processes happening inside our bodies at the molecular level. He takes viewers on a tour through a cell to show how molecules work together to create energy, and even delves into the world of photosynthesis to explain how plants create their own food.

One of the main themes of the episode is the concept of evolution. Tyson explains how the interactions between molecules can create variations in living organisms, allowing species to adapt and evolve over time. He uses the example of the peppered moth, showing how changes to its environment led to changes in the way its genes were expressed, resulting in a shift in the moth's coloration over several generations.

The episode concludes with a poignant reflection on the nature of life itself. Tyson reminds viewers that all living things are composed of the same elements and molecules, and that we are all connected to each other and to the universe around us. He describes the beauty and wonder of life as a "triumphant song," and encourages viewers to cherish and protect all living things.

Overall, Some of the Things That Molecules Do is a fascinating journey into the molecular world that underpins all of life. Tyson's engaging presentation style and stunning visual effects make the complex subject matter accessible and entertaining for viewers of all ages. Whether you're a science buff or just curious about the world around you, this episode is sure to leave you awed by the miracle of life.
