September 18, 2015Episode 35 - "So often we disconnect these things" Why study geology?
This week we discuss how geoscience can enrich anyone’s life. Join the discussion and then learn about how much cosmic dust falls on us every day!
John was on The Orbital Mechanics Episode 24 talking about SMAP.
Why Learn Geology
Your World Rocked (Slate)
Spatial thinking/reasoning
Thinking in 3D is hard… 4D is harder
3D Mouse
Resources
We need resources for our modern lifestyle
Earth is continuously changing (as pointed out in the article), so preserving it as is should NOT be the goal, but preserving a habitable planet.
Place based knowledge
Connects you directly to the land. Everyone has a “place” and by further exploring it through geology it can create a deeper connection.
Time
“Any good intro geology course is actually a course in time”
Geologic time…it’s really big!
Pale Blue Dot Photo
Puts things in perspective. Carl Sagan’s Pale Blue Dot commentary does a great job of showing spatial and temporal smallness. It doesn’t make you feel small though, it makes you feel free. Chokes me up every time; Watch it here
Fun Paper Friday
How much cosmic dust falls on the Earth everyday? Kilograms, tons? Find out on this week’s segment!
