Summer is an ideal time to learn new things and explore new ideas. This week we discuss what we want to learn over the summer and how we are going to accomplish these goals. What’s your summer manifesto? Also we get showered by cosmic rays and lightning as part of #FunPaperFriday. John’s Summer Manifesto Learn Swift programming language for mobile computing development Lynda.com Books Having a project is essential to learning a programming language. Develop classroom materials to go with some demonstrations and videos I have collected Using screen flow to capture computer screen with voice overs Use Python notebooks to capture data analysis Host materials on GitHub for free and open access Setup more effective task automation to free mind space for work Launch Center Hazel Pythonista Submit one manuscript and have another draft ready with all data processing in reproducible notebooks Editorial for writing on the mobile LaTex for writing the final paper (try Lyx) KaleidaGraph Shannon’s Summer Manifesto I also want to spend more time on Lynda.com Learn learn! Working on my first proposal Setting up my research paperwork so I can start looking into grants Getting the first chapter of my dissertation ready for submission Hone my figure making skills Learn to talk/write less!! Actually review what I did right and wrong in my classes Try to keep a doc of these things so I can revisit them. Use more Evernote Prep for Fall Teaching a new grad class - catastrophic sedimentation (if anyone has ideas, please send them to me!) FunPaperFriday This week we read a paper about how cosmic rays could give us new insight into how lighting works. Lots of places have been experiencing storms recently with severe weather and flooding. Lighting can do lots of strange things like explode trees and make glass. It has incredible power in each strike. Schellart, P., Trinh, T. N. G., Buitink, S., Corstanje, A., Enriquez, J. E., Falcke, H., et al. (2015).

This week John and Shannon discuss going outside and how important it is to our learning processes. Are we suffering from “nature deficit disorder”? We follow up the discussion with a #FunPaperFriday about playing outside. Last Child in the Woods by Louv The Nature Principle by Louv Richard Louv Website How to Raise a Wild Child by Sampson raiseawildchild.com Free Range Kids Kids Need Nature as Much as Nature Needs Them The Nature Conservancy Fun Paper Friday Dyment, Janet E. “Green school grounds as sites for outdoor learning: Barriers and opportunities.” International Research in Geographical & Environmental Education 14.1 (2005): 28–45.

Joined by Matt Herman, a geodynamics expert working on earthquake-related problems, the conversation dives into the complexities of the recent Nepal earthquake. They discuss the tectonic interactions between the Indian and Eurasian plates and how advanced GPS and INSAR technologies measure ground displacement. The vulnerability of Kathmandu due to its seismic geography is highlighted, along with the impacts on climbers at Everest Base Camp. The episode also features a fun exploration of microdroplets above hot beverages, tying scientific insights to daily life.

Explore effective note-taking techniques, from the Cornell Method to mind mapping, and find out which methods suit your style best. Discover the pros and cons of digital versus analog tools, including smart pens and classic notebooks. Learn about the intriguing impact of insects on airplane efficiency, revealing potential cost savings for airlines. Plus, dive into a fascinating project on Mercury's surface that aims to unveil the mysteries of space weathering. A light-hearted yet insightful mix of science and productivity awaits!

This week features Dr. Phoebe Cohen, a paleontologist at Williams College, who specializes in microscopic single-cell fossils predating animals. She shares her journey from biology to Earth sciences, highlighting challenges of fieldwork and the significance of educational outreach. Phoebe discusses innovative technologies like GigaPan and drone mapping that enhance student engagement through virtual field trips. The conversation also dives into the fascinating impact of breast milk on infant gut bacteria and behavior, blending science with lively anecdotes.

This week we talk about another branch of earth science, meteorology. We discuss the upcoming severe weather season and Shannon’s close call with a tornadic storm. Also updates on past stories, feedback, and fun paper friday! Kelvin-Helmholtz Instability The Kelvin-Helmholtz Instability The Brunt Väisälä frequency Story Updates and Feedback Nasa has decided to go with the boulder snatch technique for an asteroid mission launching in 2020 If you like space news and talk, checkout “The Orbital Mechanics” podcast. A very early copy of William Smith’s map has been rediscovered at the geological society. You can view a digitized version of the map online. More on the mysterious radio bursts We got some feedback about levels (thanks Celena B.) and a problem with the show logo (thanks Ross K.). We hope we have corrected both. Please keep the feedback coming in! Severe Weather We encourge you to learn your way around and use the National Weather Service webpage. Also checkout the National Severe Storms Laboratory and the Storm Prediction Center. For one of the most severe weather prone areas, Oklahoma, these three organizations are co-located in the National Weather Center Communicating weather information, or an probabilistic information is actually really difficult. Doing a hand analysis of data is still crucial to weather prediction. For example the analyst knows about isobar kinking. Oklahoma Mesonet Checkout the email “The Ticker" from the mesonet Checkout if your local weather service office offers storm spotter training classes and get to know your branch meteorologist John had a relevant blog post that talked about what an expert is and how important it is to know the fundamentals. Have a disaster plan and know what to do during an emergency! This applies to field geology work just as much. Fun Paper Friday This week is April fools, so we have a laugh with the Journal Nature. This week we learn about the coming back of dragons and climate change. Hamilton, A. J., May, R. M., & Waters, E. K. (2015). Zoology: Here be dragons.
