COSMOS Episode 3: When Knowledge Conquered Fear (2014) traces the rise of modern science during the time of the enlightenment. The transformation from a religious explanation for the workings of the cosmos to a scientific-based paradigm is told with exquisite detail through the development of the personal friendship between Isaac Newton and Edmund Halley. This episode shows the true predictive powers of science as opposed to mysticism and pseudoscience.
COSMOS Episode 6: Deeper, Deeper, Deeper Still (2014) relates our understanding (and subsequent interpretation) of reality to our rather limited perspectives of scale. Neil DeGrasse Tyson reveals reality from a subatomic scale to the entire known universe. He tells the story of evolutionary processes that work on different levels of size and scale. Tyson links the deep relationship the atoms we are made from with their creation from the ashes of stars that exploded before the sun was even formed.
COSMOS Episode 13: Unafraid of the Dark (2014) wraps-up the COSMOS series by exploring the constant fight between intelligence, compassion, and understanding, versus the darker side of the human condition, manifested by fear, ignorance, and brutality. Neil DeGrasse Tyson connects the path to salvation through the application of the principles of science to facilitate reasoning and a societal enlightenment. In the end, any journey of societal growth starts with the individual. Individual choices, based on sound reasoning and rational thought, help to form a grass-roots movement, whereby ignorance and fear slowly start to give way and lose their appeal. This is the main message the COSMOS series endeavors to relay. This final episode delivers that message right on-time.
