COSMOS Episode 5: Hiding in the Light (2014) gives an in-depth explanation of the fascinating phenomenon of light. Neil DeGrasse Tyson traces our earliest, first ponderings of light in ancient China through modern spectroscopy and the phenomenon of dark matter. He artfully links world-wide cultural contributions over the centuries concerning light to create an immersive story-line that holds a student’s attention. Yes, this is actually possible!
COSMOS Episode 12: The World Set Free (2014) is a great environmental wake-up call for the citizens of earth. Neil DeGrasse Tyson effectively demonstrates the parallels of the runaway greenhouse effect that occurred on Venus (and the hellish conditions it produced) and what we are currently doing to the earth. Tyson presents solid, scientific evidence to support his claims. But does humanity have the will to take the steps necessary before it is too late?
