Don't Panic Geocast

We want to wish you happy holidays and invite you to join us while John was at AGU. This show should have been released a week ago, but John got very ill at AGU and took several days to recover. Thank you for the well wishes and sticking with us! AGU Fall Meeting 5 Tips for Surviving your First Conference John didn’t get to see the Elon Musk lecture.

This week we re-visit one of our favorite shows while everyone is outside or in their turkey food-coma here in the US. We also read some listener mail about last week's episode on earthquake magnitudes!   Time is a very complex subject that you can devote your entire life to. Today we’ll cover a few of the basics and enough to get your interest up! We’ll see that it’s difficult to know what a second is and how long relative times are, but absolute time is even messier! We also discuss dried coffee and tetris! Importance of Time (and why it’s on a geology show) It synchronizes the world and our human interactions (need minutes - hours accuracy generally) It allows us to talk about events in a common coordinate system Allows synchronization of scientific measurements and comparison of data sources. This is really important for seismometers for EQ location! Let’s us use GPS! 1 billionth of a second (nano second) error in 1 GPS satellite, GPS receiver is +/- 1 ft to satellite, which is 2–3 feet on Earth. Early

This week we talk about Bill Nye, earthquake magnitudes, and coffee. Bill Nye John got to see Bill Nye (@BillNye) talk at Penn State! News article with photos! Earthquake Magnitudes Earthquake Size (C. Ammon) Challenge is that earthquakes span a huge dynamic range. We measure ground displacements over about 9 orders of magnitude.

Shannon was at the GSA 2015 meeting in Baltimore Maryland. She also won a raffle there for a Rite in the Rain notebook and holder. The meeting app worked well, but we’re both nervous after the AGU app last year. This is episode 42. A very important number to the show!

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 t

Classes are back in session, and we’re back to normal episodes. Join us to talk about Brunton pocket transits, argue about strike and dip, and discuss the zombie apocalypse. AAPG abstracts are due September 24! Windows 10 isn’t supporting external USB microphones right now. What? Checkout Angie’s beautiful photos. Part 1 Part 2 What is a Brunton? A compass, but a really expensive one with lots of features Generally referring to the conventional pocket transit About the size of a deck of cards, but worth $500 It’s a very accurate compass/clinometer combination that we use to take strike and dip measurements amongst others Can also sight bearings to objections or angle from horizontal by using the sights and mirror Can set the magnetic declination. Just don’t forget! Strike and Dip Two numbers that define the orientation of a plane in 3-dimensional space using an agreed upon handedness convention Dip direction is the direction water would run if poured on the rock, angle is how steep that rock is inclined

Intro The Orbital Mechanics highlighted how little we know about planetary formation, so let’s talk about Pluto and what we’ve learned from the New Horizons Mission. Pluto Basics Officially a dwarf planet in the Kuiper belt About 0.18 the radius of Earth Mass 0.178 of the moon’s Very low density Gravity 0.63 g Neptune and Pluto were both predicted to exist from orbital perturbations of Uranus Percival Lowell (founder of Lowell observatory) started the hunt for pluto in 1906. Tombaugh found Pluto using a blink comparison technique Moons of Pluto Orbit is chaotic, we can predict forwards and backwards for several million years, but over the Lyapunov time we have no idea.
