Awards!

We placed in the “Top New Artists” and “Most licensed by Public Radio Remix” awards at the 2011 PRX Zeitfunk Awards. This is quite an achievement, especially since the show has only been available through PRX.org for half a year.
Top-Down Cause
We stroll through the history of causal thought in medicine (and science) and entertain an alternative approach that is getting some traction in physics: top-down causation.
Medicine (and science) used to believe that something happened because of an enormous amount of causes pilled together. This hollistic approach gave way to the simplifying and reductionistic view of nature that made science so successful. Now, this reductionist approach has reached some limitations in many areas of physics and Christopher Jargocki attempts to explain a way of thinking about cause and effect: the whole system determines the parts. This new approach is called top-down causation and it’s very exciting.
Voices:
Christopher Jargocki - University of Central Missouri Physics Dept. He is a Polish-born American physicist, author, and translator who is a professor as well as the Director of the Center for Cooperative Phenomena. His four books, the last two co-authored with Franklin Potter, deal primarily with paradoxes and misconceptions in physics and astronomy.
Alfredo Morabia, MD - Mailman School of Public Health at Columbia University. He was board certified in Internal Medicine at the University Hospital of Geneva, where he specialized in Occupational Medicine. He practiced both in Switzerland and Italy, before receiving a PhD in Epidemiology and an MHS in Biostatistics from the Johns Hopkins University School of Public Health. Dr. Morabiz returned to Switzerland and served as professor and head of the division of Clinical Epidemiology at the University Hospitals of Geneva from 1990 to January 2006. He is currently professor of Epidemiology at the Mailman School of Public Health and at Queens College, City University of New York.
The Sound of Chaos
Why can’t you predict the weather in a few days in advance? In this short, we explore the fundamental unknowable nature of chaotic systems. Then we hear a song of weather data that lets us grapple with chaos in an aural way.

Michael Esfeld - Univeristy of Lausanne. He researches the structures and causation in the philosophy of physics and the philosophy of mind. His physics interests are summarized here:
Structural realism is a form of holism in the philosophy of physics, claiming that in the domain of fundamental physics, there are in the first place certain structures in the sense of networks of concrete physical relations instead of objects whose identity is constituted by intrinsic properties. We develop a conception of moderate ontological structural realism that recognizes objects as that what stands in the relations, but those objects are characterized mainly by the relations in which they stand. We apply this conception to quantum physics and to space-time as treated in general relativity theory. We currently investigate whether and in what sense these structures can be considered to be causal, their being causal distinguishing physical from mathematical structures and grounding the direction of time.
Ned Hall - Harvard University. He works mainly on metaphysics and philosophy of science, with a special emphasis on philosophical problems associated with the foundations of quantum physics. In the philosophy of physics, his current research focuses on disentangling the various problems associated with the quantum mechanical treatment of measurement, and on elucidating the implications of and conceptual basis for the usual quantum mechanical description of systems containing identical particles. His current interests in the philosophy of science center on the analysis of natural laws and their role within scientific theories. His other work has included investigations into the connections between probability theory and the logic of conditionals, the epistemology and metaphysics of objective probability, and the analysis of causation. He recently edited (with John Collins and L. A. Paul), Causation and Counterfactuals.
Nathalie Miebach - Her work focuses on the intersection of art and science and the visual articulation of scientific observations. For her most recent project called “Recording and Translating Climate Change”, she gathers weather observations from specific ecosystems using very simple data-collecting devices. The numbers are then compared to historical / global meteorological trends, before being translated into sculpture. By examining the complex behavioral interactions of living/non-living systems between weather and an environment, she hopes to gain a better understanding of complexity of systems and behaviors that make up weather and climate change. Lately, she have also started to translate the data into musical scores, which are then interpreted through sculptures as well as through collaborations with musicians. Her aim is twofold: to convey a nuance or level of emotionality surrounding my research that thus far has been absent from my visual work and to reveal patterns in the data musicians might identify which I have failed to see.
Jonathan Schaffer- Australian National University. He received his PhD from Rutgers University in 1999. He joined the ANU in 2007, from the University of Massachusetts-Amherst. Jonathan’s main interests are in metaphysics and epistemology. His current research centers on metaphysical monism, coupled with contrastive theories of causation and knowledge.
Richard Scheines - Carnegie Mellon University. His research is on causal discovery, in particular the problem of learning about causation from statistical evidence. The theoretical and computational dimensions of this work have come to be called the TETRAD project, which represents nearly 25 years of collaboration with Clark Glymour, Peter Spirtes and many, many others. Building efficient and practically useful algorithms for causal discovery is as much computer science as philosophy, and thus I have a courtesy appointment in the Machine Learning Department.
Prof. Scheines also put a lot of effort into building and researching the effectiveness of educational software, ranging from intelligent proof tutors to virtual causality labs to a full semester course on Causal and Statistical Reasoning. Because of this work I have a courtesy appointment in the Human-Computer Interaction Institute.

Levels of Cause
Cause and effect seems so easy to grasp but is often slippery when we think about it in detail. In this show, we hang to the slippery topic and ask these questions: Which level is the right level of causal explanation? How does probability figure into cause and effect? How does cause fit into how the rest of the world is set up?

He is particularly interested in the works of Spinoza and the development of a viable rationalist epistemology. He is currently working on a dissertation that examines the foundations of Spinoza’s metaphysics and reexamines the traditional Rationalist/Empiricist dispute.
Innate Cause
Philosophers and scientists explain how the notion of cause and effect is a primitive notion in infants. We consider why this makes evolutionary sense and then turn our focus toward neuroscience and education, where new causal thinking is making an impact.

Biological Death
We consider an unusual understanding of death – a biological one. Prof. Tyler Volk describes organisms tuning their lifespan to their surroundings, the theory of “fly now die later,” and painting a personal understanding of death with help from biology.
Voice:
Tyler Volk - New York University Biology Dept. He is biology professor and Environmental Studies Director and has been active in what might be called biosphere theory, or Gaia theory (with “biosphere” or “Gaia” defined as the system of atmosphere, ocean, soil, and life). Are there unifying scientific principles that govern diverse phenomena within the biosphere? Past work in Gaia theory has primarily focused on the state of the global environment that surrounds living things, for example, on the chemistry or temperature of atmosphere or ocean. He has been suggesting another approach. This involves close attention to how organisms fit into and in fact make the chemical cycles, the so-called biogeochemical cycles. A potential universal metric for these cycles is the “cycling ratio.” This is the ratio of an element’s flux into the photosynthesizers within a system (either the biosphere system or subsystems within) relative to the flux of that same element across the system’s boundary into the system. Volk explores how this metric could be useful for biosphere theory, as a way of comparing systems with life across different scales of space, essential nutrients, and evolutionary time.
