321 – Societal Change and the Climate

I am interested in societal change: how can a complex society with lots of emergent (perhaps unintended) behaviors make a conscious change, such as transitioning to a more sustainable economy? We discussed this from an engineering perspective in the episode on Modeling Socio-Technical Systems, and we’ve looked at it historically in the episode on Societal Complexity and Collapse. In this episode we look at the topic more from the perspective of civil society and politics. Our guest ist Maja Göpel; she heads the German government’s Advisory Council on Global Change and has also written a book called The Great Mindshift on the topic.

A few months ago, a collaboration called the Event Horizon Telescope presented the first direct image of a black hole; or more specifically, of the radiation created by accelerated particles at its event horizon. The EHT is a Very Large Baseline Interferometer, in which radio telescopes all over the world are computationally connected to obtain resolutions that are not possible with one telescope. In the episode I chat with Heino Falcke, the chair of the EHT science committee, about the science, the telescope, what it took to get it going, and image reconstruction.

In June 2019 I had the pleasure and honor to fly in an F-16D with the USAF Thunderbirds. The episode covers the medical briefing about how to prevent motion sickness and how to deal with Gs, suiting up with flight suit, g-suit, harness, helmet and mask, the briefing with my pilot Maj. Jason Markzon, the flight itself with commentary, an interview about the Thunderbirds with Jason, as well as a reflection on what the flight meant to me, recorded together with Nora.

In May I visited ALICE, one of the four large experiments at the LHC and talked with Despina Hatzifotiadou. We briefly discussed the science that ALICE is interested in, and then spent the majority of the time dissecting the detector to understand its components and how they detect the various products of particle collisions.

315 – Modeling Socio-Technical Systems

Socio-technical systems are systems where (groups of) humans interact with (non-trivial) technical systems; an example is the power grid. The people, the technical system and the combination might easily lead to complex behavior that is hard to predict and control over the long term. However, as illustrated by, for example, the need to transition our energy infrastructure to a more sustainable structure, it is necessary for society to “control” such systems. Igor Nikolic is a professor at the TU Delft where he uses agent-based modeling approach to try to understand, and thus help control and evolve such systems. We discuss the systems, the challenges as well as the modeling approaches.
