Carl Sagan - How We Know The Earth Is Round

I think it is important to understand who Carl Sagan was, how he spoke, and how he explained the fundamental mechanics of our world that science has uncovered.

It is 2018 and there still seems to be a select group in our population (of course, present company excluded) that believes that the earth is flat. Not only do I respectfully disagree with that notion, I offer this video as scientific evidence of why the earth is round.

Additionally, I believe that the term Science has become an abstract concept in our contemporary vernacular rather than a description of the discreet methodology used as a  "systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe."


Here is more food for thought:

This is a video of Richard Dawkins discussing The Selfish Gene at the Royal Institution in London.

I confess that I am somewhat obsessed with this YouTube channel and I recommend RI lectures to anyone interested in learning how our world works.

The Royal Institution has a distinguished history of scientific learning. It is a place where Science is not something one "believes in" but a place where scientific discoveries are demonstrated repeatedly, rigorously critiqued, verified, peer-reviewed, and offered for people to see for themselves.
