I
continue to be awed by Neil deGrasse Tyson’s Cosmos: A Spacetime
Odyssey. Each episode just gets
better and better, and the third episode, “When Knowledge Conquered
Fear” is no exception. Even though I already know most of the
information it’s covering, I continue to be entranced by its
presentation. And that’s not to say I haven’t learned anything.
This episode, in particular, taught me a lot about Edmund Halley and
Robert Hooke that I didn’t previously know. What’s more, it
continues to be a great introduction to all there is about science
and a perfect spiritual successor to Carl Sagan’s original Cosmos.
In
“When Knowledge Conquered Fear”, Tyson takes a look at the human
ability of pattern recognition, both in the ways that it has helped
us and hindered us. The episode starts with a discussion of comets
and how early civilizations interpreted them as omens of disaster,
then moves into the reality of what we know about comets today,
taking us on a journey out to the Oort Cloud and introducing us to
the not-well-known Jan Oort, whom the Oort Cloud is named after.
