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
- Thinking in 3D is hard… 4D is harder
- 3D Mouse
- 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.
- “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!
