Reason with Science
Welcome to "Reason with Science", the podcast that explores the intersection of reason and science in our everyday lives. Billions of years of evolution led to a species which is asking questions about its own existence. This quest of humans is not possible without science. As we navigate an increasingly complex world, it's more important than ever to approach issues with a clear and evidence-based understanding. In this podcast, we'll dive into the latest research, explore fascinating topics, and interview experts in their respective fields to help us make sense of the world around us.
