Full Show: Peter McCoy - Mycology |In Search of Soil #7
One of the members of the soil ecology that is mentioned on a generalized note is fungi. Although we recognize their importance, there aren’t a lot of specifics tied to mycology—and that’s because there’s still a lot we don’t know about them. As a branch of science, mycology is still relatively new and a lot less studied compared to other fields of study. Today, we have mycologist Peter McCoy to shed some more light on fungi from a deeply mycological perspective. Peter McCoy is a mycologist and mycology educator with 17 years of experience. Known for mushroom cultivation and mycological remediation, he authored Radical Mycology, a 650-page book of condensed knowledge about fungi. He also created Mycologos in response to the growing need for accessible mycological education.

439: Going to North Korea: Part Two | Stereo Sunday
This is the third episode of Stereo Sunday, a little Stereo app-sponsored experiment we’ve been doing live in front of a studio audience of you! Download the Stereo app for iOS or Android here. Full show notes and resources can be found here: jordanharbinger.com/439 On This Week’s Stereo Sunday, We Continue Our Adventures in North Korea (Part One Can Be Found Here): * Gabe and Jordan traveled to North Korea (aka Democratic People's Republic of Korea -- or DPRK) together several times between 2011 and 2016. * As bizarre as you've heard North Korea can be, the reality is probably even weirder. * What do you actually do on a trip to North Korea? * How long does a typical itinerary last? * Should you strike up conversations with random people in transit (or let them tell you what you can and cannot read)? * What's so impressive about the Arirang Mass Games? * What should you do if you're accidentally caught up in propaganda production? * How do North Korean subways differ from what we've come to expect in the West? * How can throwing a frisbee thaw international iciness? * How much warm beer can you get for $20 cash money American? * Want to know what it's like to live out a scene from a David Lynch-directed musical? Just dine at a North Korean restaurant! * Will you get thrown into a gulag for performing the Star-Spangled Banner at karaoke in North Korea (or should you)? * Why did Kim Jong-il allegedly accompany his mother into battle as an infant? * In the US, we have freedom of speech. In the DPRK, you don't even have freedom from speech. * Why do so many Americans and Canadians own businesses in a town on the Chinese-North Korean border? * After talking about all the upsides of visiting North Korea as an American, what are the downsides? * If you visit North Korea, what will you encounter that you won't hear about on American network news? * We also answer some of our listener questions that came in live during the show! * Download the Stereo app here and participate with us live on Friday, November 20th and 27th, at 2 p.m. PST! * Connect with Jordan on Twitter at @JordanHarbinger and Instagram at @jordanharbinger. * Connect with Gabriel on Twitter at @GabeMizrahi.

#664: The Masters of the Art of War
Looked at from the heat of combat, war can seem disorganized and chaotic. But overarching the conflict is typically some kind of thoughtful, well-ordered, even scientific strategy that is influencing when, where, how, and why dueling forces have met. My guest today will introduce us to a few of the military philosophers and tacticians who made the most significant contributions to the art of strategy over the last couple millenia. His name is Andrew Wilson, and he's a professor at the Naval War College, as well as the lecturer of the Great Courses course, Masters of War: History's Greatest Strategic Thinkers. We begin our conversation with a brief overview of what martial strategy is, why civilians should study it, and how the contrast between generals Eisenhower and Patton delineate the difference between strategy and operations. We then survey several of history's most influential war strategists, and the contexts in which their theories and doctrines were born. This tour includes a discussion of how Sun Tzu used The Art of War to argue that a new type of war in a new type of society required a new type of general who could process conflicts like a supercomputer, and a dive into how Carl von Clausewitz emphasized the importance of understanding how complexity, irrational passions, and creative genius underlay contemporary warfare. We end our conversation with how military strategy has or hasn’t changed in the 21st century.
