The most surprising discovery in fundamental physics during my career as a scientist was undoubtedly the acceleration of the universe, announced in 1998. The most straightforward explanation for these observations is a positive cosmological constant, or vacuum energy. I talk about the origin of the idea with Einstein, how quantum physicists started to think about it and understand the "cosmological constant problem," as well as how its discovery also raised the "coincidence problem." This is the first of two connected solo episodes; the next will be on theories of dark energy that are not the cosmological constant.

As AI is integrated into scientific practice, the practice of science itself is changing. AI models that summarize, categorize, simulate, and predict not only stand to accelerate scientific research; they now sit inside these practices, alternately enhancing and eroding craft while shifting how questions are posed, what counts as evidence, how tacit judgment is taught and exercised, and reshaping trust in results.   Dr. Kristin M.

What if we could turn economic complexity into strategic understanding? In this episode, we sit down with David Rushing Dewhurst, Ph.D., a program manager in DARPA\'s Information Processing Techniques Office, IPTO. Dewhurst works at the complex intersection of economics, data science, and national security to develop tools that help America navigate a world where economic competition has become a primary battlefield. Dewhurst shares his unconventional path to the agency and takes us through two of his programs: Anticipatory and Adaptive Anti-Money Laundering, A3ML: An innovative program that aims to eliminate global money laundering by treating it as an economic supply-and-demand problem, while preserving privacy through a decentralized approach. National Security Economic Theory, NASCENT: A program focused on establishing a principled theoretical foundation for geoeconomics and building generic playbooks for economic statecraft. Tune in to discover how Dewhurst is redefining the tools of economic statecraft to prevent pan-domain strategic surprise. 

There's an organizational tool, almost always used by Human Resources, called competencies. Even though it's a fairly popular model for thinking about professional development, it's a terrible system we don't recommend. But if you have to use competencies, here's how.

We all have that one person, don't we, whose success makes us painfully aware of our own shortcomings? A person who serves as a reminder of all the great things we could have been, but aren't. Hearing news of their latest achievement is liable to ruin our entire day, as we rush headlong into reflecting on how flawed and disappointing we are. But what if it's not that simple? What if the reason that person is doing so well is not because they're better than you, but because the two of you have different values, and therefore different priorities? In this episode, I'm going to reframe your depressing comparisons and show you how you can use them to tune in to what you care most about. Turn that frown upside down, my friend, and settle in for some uplifting truth bombs.You can find my Core Values exercise here, and the Wheel of Life here.

In Chilling Effects: Repression, Conformity, and Power in the Digital Age (Cambridge UP, 2025), Jonathon W. Penney explores the increasing weaponization of surveillance, censorship, and new technology to repress and control us. With corporations, governments, and extremist actors using big data, cyber-mobs, AI, and other threats to limit our rights and freedoms, concerns about chilling effects – or how these activities deter us from exercising our rights – have become urgent. Penney draws on law, privacy, and social science to present a new conformity theory that highlights the dangers of chilling effects and their potential to erode democracy and enable a more illiberal future. He critiques conventional theories and provides a framework for predicting, explaining, and evaluating chilling effects in a range of contexts. Urgent and timely, Chilling Effects sheds light on the repressive and conforming effects of technology, state, and corporate power, and offers a roadmap of how to respond to their weaponization today and in the future. You can find more information about Jon at his website: https://jonpenney.com/ Jake Chanenson is a computer science Ph.D. student and law student at the University of Chicago. Broadly, Jake is interested in topics relating to HCI, privacy, and tech policy. Jake’s work has been published in top venues such as ACM’s CHI Conference on Human Factors in Computing Systems.

Now, Dr. Elizabeth Sawin has dedicated her career to the theory and practice of creating change in complex systems. In 2021, she founded and is currently the Director of the Multi-solving Institute. This interview discusses her book Multisolving: Creating Systems Change in a Fractured World (Island Press, 2024) After studying many successful efforts around the world, where people created systems-change by building connections across silos, she developed the Multi-Solving approach to more effectively address equity, climate change health, well-being, and economic vitality as integrated issues. Prior to her current position, Beth co-founded the think tank Climate Interactive to develop tools and project possible futures for grappling with the complexity of the climate system. In this regard, she led efforts to integrate measures of equity, health, and well-being into decision-support computer simulations. Beth writes and speaks about multi-solving and leadership in complex systems for both national and international audiences. She has over 40 publications, both in scientific journals, as well as more populous literature, such as: Non-Profit Quarterly, The Stanford Social Innovation Review, The Daily Climate, U. S. News, as well as… in the New York Times and the Washington Post. Beth graduated from Dartmouth College with majors in Biology and Chemistry and subsequently received her PhD in Neuro-Biology from the Massachusetts Institute for Technology Learn more about your ad choices.
