Neil deGrasse Tyson Explains Mercury in Retrograde

Teacher or professor: StarTalk
Subject: Astronomy
Content of the Lesson: Mercury is in Retrograde. What does that mean for you, if it means anything at all? Neil deGrasse Tyson is here to set the record straight. Alongside comic co-host Chuck Nice, we take a trip back in time to understand why this phrase has survived since the reign of the ancient Greeks. Discover what is actually happening when a planet goes into retrograde. You’ll learn what the world was like before the scientific method was widely used and how the implementation of experimentation and hypothesis catapulted civilization forward. We trace our understanding of the planets from a time where humans thought Earth was at the center of the universe. Find out why the ancient Greeks referred to planets as wanderers when they first discovered them. You’ll hear why the foundations of astrology have no justification in a scientifically literate and modern world. Then, we investigate why humans are in such need to have things explained. All that, plus, Neil shares why it takes a lot of hubris to think the universe actually cares about you.
