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.

#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.
