Rutgers Professor Michael Lesk talks to Michael and Dave about everything from computing and information retrieval in the 1960s, to railroad signaling and recognizing giraffes, to the difference between astronomers and computer scientists, to Colonial Pipeline and the real AI challenge.   [Title image courtesy of Mike Lesk]

Professor Tina Eliassi-Rad of Northeastern's Network Science Institute talks with Michael and Dave about topics ranging from graph structures and machine learning to AI ethics and the nature of democracy. [Title image courtesy of Tina Eliassi-Rad]

Dave is feeling glum about technology -- and by extension about the impacts of computer science, the exploitation of science in general, and the hope for sustainability and truth in society. Michael helps sort it all out.

Michael and Dave talk to Heather J. Lynch, Associate Professor of Ecology and Evolution at Stony Brook University, about awards and leaving physics, about saving penguins and the planet, and more.

Heather Lane, machine learning researcher and senior architect at athenahealth, joins Dave and Michael in a talk of many things, of the thermodynamics of life, of the US healthcare industry and life after academia, of coming out as transgender.

Fil Menczer, professor and director of the Observatory on Social Media at Indiana University, joined Michael and Dave on the day after the 2020 USA presidential election. Fil revealed how his 1990s Artificial Life research set the stage for his current work, focusing not just on the facts of disinformation and hoaxes and conspiracy theories and social bots, but also how to identify and fight them.

Jeff Bigham, an Associate Professor at Carnegie-Mellon's Human-Computer Interaction Institute, joins Michael and Dave in a wide-ranging discussion of human-computer interactions, AI threats and opportunities, and systems and organizations made of both computers and humans.

Michael and Dave discuss the meaning of the reward function, and its consequences for AI and human society.

Dave tries to explain his "We are coders" approach to cognition to Michael, as part of developing the second lecture in the "Introduction to Classical Hyperspace" series. First lecture

Computer scientists Emma Brunskill of Stanford and Phil Thomas of UMass Amherst join Michael and Dave in a four-way discussion of safety and fairness in AI and machine learning. [The primary paper discussed, Preventing undesirable behavior of intelligent machines, is by Philip S. Thomas, Bruno Castro da Silva, Andrew G. Barto, Stephen Giguere, Yuriy Brun, and Emma Brunskill, and can be accessed for free via paper in Science ]

Michael and Dave talk with UC Berkeley sociologist Jenna Burrell about topics ranging from algorithmic fairness and transparency, to anthropology and epistemology, to viral tweets and why small is beautiful. [Title image courtesy of Jenna Burrell]

Dave hates theory.  Michael disagrees.

Michael and Dave talk with mathematician, computer scientist, and puzzle maker Peter Winkler, about topics ranging from randomness to free will, and combinatorics to Sleeping Beauty, and John Horton Conway to Erdős number 1. And don't miss the bonus puzzle! Conway's (first) Princeton Lecture [Title photo courtesy of Peter Winkler]

Michael and Dave talk about pandemic models and simulation journalism, programming languages, and what people really want. Washington Post's simulator is here

Michael and Dave talk to Brown University neuroscientist Michael J Frank about topics from brains and minds, to engineering and machine learning, to dopamine and Parkinson's disease and New Age woo.

Computer scientist and biologist Melanie Moses joins Michael and Dave in a conversation ranging from biology nerds vs computing nerds to the future of justice in the United States, with a whole lot of scaling along the way.

Michael Carbin, Assistant Professor of Electrical Engineering and Computer Science at MIT, joins Michael and Dave to discuss neural net lottery tickets, computing with uncertainty and more. [Cover photo courtesy of Michael Carbin]

Zander Furnas helps Dave get a clue about political science, in theory and in practice -- from authoritarianism to democracy, and from Congressional staffer's incentives to Elizabeth Warren's plan for lobbyists, and whether there's hope for society after all.

Dave and Michael revisit the meaning of life (the subject of the second Computing Up conversation) in the context of politics and society and human destiny. [Photo by Jeffrey Lee on Unsplash]

Inspired by a WIRED profile of Karl Friston, Dave and Michael talk about theories of everything, and theories thereof. [WIRED Article: https://www.wired.com/story/karl-friston-free-energy-principle-artificial-intelligence/ ]
