In this enlightening episode, we navigate the intricate world of risk and resilience of urban systems with Dr. Logan. Holding a Doctorate from the University of Michigan and an active member in numerous professional organizations like the Society for Risk Analysis and the Association of American Geographers, Dr. Logan's contributions to the field are formidable. His research paves new ways in designing cities resilient to climate change through the lens of risk science, systems engineering, modeling, and statistics.The episode centers around Dr. Logan's recent groundbreaking paper on sea-level rise (SLR). While traditionally, the focus has been on properties at risk of inundation due to rising sea levels, Dr. Logan proposes an often overlooked but critical metric: the risk of population isolation. His team’s findings suggest that a significant number of people might face isolation, cut off from essential services, much before their properties are inundated. These revelations have substantial implications for how we approach SLR in terms of policy, planning, and even human rights.Through the paper’s insights, Dr. Logan emphasizes the importance of considering not just the physical flooding but the broader, cascading consequences that SLR can introduce. This holistic understanding can dramatically reshape how cities and countries approach SLR, ensuring that adaptation strategies are comprehensive, efficient, and prioritize the well-being of at-risk communities.Journey with us into a world where the rising tides pose risks that stretch beyond mere property damage. Learn about the complexities of planning for a future where inundation and isolation go hand in hand and discover the strategic interventions that can help us build a resilient and inclusive future.Urban Systems, Resilience, Climate Change, Risk Science, Sea-Level Rise, Population Isolation, Inundation, Adaptation Policy, Infrastructure, Displacement, Relocation, Global Climate Adaptation.Logan, T.M., Anderson, M.J. & Reilly, A.C.

In this captivating episode, we dive deep into the intersection of mathematics and neuroscience with Dr. Dimitris Pinotsis. Boasting a PhD in Mathematics and an MSc in Theoretical Physics from the renowned University of Cambridge, Dimitris' academic journey is truly impressive. After publishing numerous papers in mathematics and physics, he shifted his focus to his true passion: neuroscience. His collaborations with leading minds in the field, such as Peter Grindrod, Karl Friston, and Earl Miller, have fortified his expertise in machine learning and developing mathematical methods to analyze brain data.Currently positioned as an Associate Professor at City—University of London and maintaining a Research Affiliate status at MIT's Brain and Cognitive Sciences Department, Dimitris has earned numerous accolades in his career. His commitment to the field is evident from receiving multiple fellowships from prestigious institutions to being honored with several awards, including the Poincare Institute Award.In this episode, we'll also unpack his latest paper which explores a groundbreaking concept: how does the brain's anatomy influence its function? Contrary to the prevailing view, Dimitris and his team propose that the geometry of the brain plays a more pivotal role in its dynamics than previously believed. Through analysis of human MRI data, the team presents evidence that brain activity can be better understood by examining the resonant modes of the brain's geometry instead of just its complex interregional connectivity. This finding has far-reaching implications, reshaping our understanding of how task-evoked activations span across the brain and the role of wave-like activity.Join us as we traverse the intersections of math, brain anatomy, and function, unveiling the mysteries of the human mind with Dr. Dimitris Pinotsis.Pang, J.C., Aquino, K.M., Oldehinkel, M. et al.

Our speaker, Dr. Mertens, discusses in-depth ground-state thermalization due to instantaneous horizon creation in a gravitational setting and its condensed matter analog. Dr. Mertens sheds light on the implications of a sudden change in position-dependent hopping amplitudes in a one-dimensional lattice model, leading to the emergence of a thermal state that accompanies the formation of a synthetic horizon. Throughout the discussion, we unravel the striking parallelism between the resulting temperature for long chains and the Unruh temperature, given that the post-quench Hamiltonian matches the entanglement Hamiltonian of the pre-quench system. We analyze the outgoing radiation from these synthetic horizons and formulate the conditions required for these horizons to behave as a purely thermal source. This podcast episode offers a unique opportunity to learn more about the interplay between quantum-mechanical and gravitational aspects and to understand how these complex ideas might be tested in a laboratory setting. An absolute must-listen for anyone intrigued by the junction of quantum mechanics and gravity and eager to keep up with the latest theoretical developments in the field.

In this episode, we delve into the fascinating world of cosmic metallicity and its role as a unique record of the Universe's total star formation history. Our focus is a groundbreaking paper analyzing oxygen abundance in the nearby system, Markarian 71. This study presents compelling evidence that challenges long-held beliefs in the astrophysics community, particularly in relation to the 'abundance discrepancy factor'.Through a meticulous combination of optical and far-infrared emission line measurements, the study aims to correct for temperature fluctuation effects. The results present an intriguing twist – a stark inconsistency with the metallicity derived from recombination lines. This finding effectively rules out the longstanding hypothesis that the abundance discrepancy factor is primarily due to temperature fluctuations, at least for Markarian 71.As we explore these findings, we'll be discussing the wider implications for our understanding of metallicity across cosmic history. Additionally, we'll look ahead to the potential of recent data from the James Webb Space Telescope and the Atacama Large Millimeter Array, promising to shed further light on this cosmic mystery within the first billion years of the universe.Join us as we journey through the cosmic mists and bring the heavy elements of the Universe into sharper focus.
