Hakeem Oluseyi: An unexpected life in Science, and unpopular truths
I confess that Hakeem Oluseyi had not really risen on my radar screen until the last year or two. I was aware of the National Society of Black Physicists, having sometimes gotten notices about is meetings, but, being generally unsupportive of current efforts to compartmentalize scientists by their identity, I hadn't really paid much notice to it. Then, in one of those ironies that periodically makes one feel better about the vicissitudes of fortune, I learned more about him only after people had attempted to cancel him. When I read about Hakeem's brave and impressive campaign to uncover the truth about James Webb after a small but unduly loud group of physicists, whose actions seem to be centered about their mutually celebrated victimhood, argued that the James Webb Space Telescope should be renamed, my interest in him, along with my respect for him, rose considerably. Prompted by this newfound interest, I read a book he had co-authored, entitled, A Quantum Life: My Unlikely Journey from the Street to the Stars, and I was fascinated by the remarkable transformation of a hillbilly turned drug dealer into an academic. Here was someone who could have reveled in begin a victim by lashing out in hate, but instead was inspired to improve himself and those around him. I decided I wanted to delve deeper into the man, his life, his science, and his recent unfortunate experiences while holding firm to the search for truth in a podcast. It was a fun, and fascinating few hours. Hakeem and I both like to joke as well as tell stories, and we are both serious about the effort to understand nature, and to share our enthusiasm about that effort. I hope the combination of our mutual enjoyment about life and science, along with learning about his own story will inspire, entertain and inform. I certainly enjoyed our discussion and I hope you will as well. As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

Martin Rees: If Science is to Save Us, Part 2
This is part two of the second podcast dialogue we are airing with renowned astrophysicist, Astronomer Royal, and former President of the Royal Society, Lord Martin Rees. The first time I sat down with Martin for the Podcast we discussed his life in science, and topics ranging from the state of modern cosmology to the potential conflicts between science and religion (which he views as minimal, and I don't). Martin's thinking, and his expertise, go far beyond these topics however. Based on his experience at the Royal Society, as an elected member of the House of Lords, and working with the Center for Existential Risk at Cambridge, Martin has thought carefully about the challenges we face as a society in the 21st century, and how science can be marshaled to help us address these challenges. He has written a new book on the subject called If Science is to Save Us. I thought it would be useful and interesting to sit down with Martin to discuss the ideas he raises there, and our conversation turned out to be so wide-ranging that we are presenting it in two separate episodes of the podcast. I am sure you will find his thoughtful and incisive comments both provocative and inspiring. As always, I benefitted greatly from my conversation with him, and I hope you do as well.

An Origins Podcast EXCLUSIVE: A Dialogue with Cormac McCarthy About Science, on the occasion of his newest book releases
Cormac McCarthy is a literary icon. Winner of the National Book Award and the National Book Critics Circle Award for his novel All the Pretty Horses, and the Pulitzer Prize for his apocalyptic novel The Road, Norma's earlier novel, Blood Meridian has been labelled The Great American Novel. Many people did not know that this cultural giant is also fascinated by, and amazingly knowledgeable about science. Reading his newest books, The Passenger and Stella Maris (released this week!), however, and that becomes obvious. The protagonists are mathematical and physics prodigies, and just as one may requires a dictionary to keep up with the the remarkably diverse prose in Cormac's writing, some people may need to consult some popular books on science to fully appreciate the scientific asides sprinkled throughout both volumes. I first met Cormac at the Santa Fe Institute back when I was considering a possible position there as its Director, some years ago. I was shocked to walk into the kitchenette there and discover him, as I had no idea that is where he spent his time. But, as we discuss in our dialogue, he moved to Santa Fe at the invitation of Nobel Laureate physicist Murray Gell Mann to join the new Institute. Cormac and I became fast friends then, and have remained friends ever since. The best hour of radio I ever did was with Cormac and Werner Herzog, on the occasion of Herzog's film Cave of Forgotten Dreams, where both Cormac and Werner talked with amazing authority about the evolution paleontology of early modern humans. Then later, he honored me by asking if he could copyedit the paperback version of my book Quantum Man, a scientific biography of Richard Feynman. He said he wanted to make the paperback version 'perfect', in part by removing all exclamation marks and semicolons.. Of course I said yes, and we added his name as copyeditor on the front page! I have known that Cormac is extremely reluctant to appear in public or do interviews. He agreed to appear in our film The Unbelievers, which was a great gift, but has often demurred when I have asked him to appear in other public panels on subjects we love to talk about in private. So, when I asked him if, on the occasion of the publication of his new books, the first books in 16 years, if we could sit down and record a conversation about science for The Origins Podcast, I was shocked and thrilled when he agreed. He is 89 years old now, and I was so pleased to have the chance to record some of his thoughts on science for posterity. He invited us into his home for an afternoon conversation after a long lunch, and the conversation that ensued was much like the conversations we have had over the years. Cormac loves to discuss science, but prefers to listen to physicists talk about their work rather than initiate conversations. He is, after all, notoriously laconic. But when he does speak about science, his insights are fascinating. Using some of the ideas discussed in his new books a launching points, our discussion ranged over quantum mechanics, the role of mathematics in science, and whether there will ever be a theory of everything. There were a variety of challenges that day, including the difficulty of filming something in a sunlight room without window shades, but the end result was unique and memorable. I hope you agree.

Geoff Marcy: The Search for Exoplanets and Life Elsewhere in the Universe
Geoff Marcy has been pioneer in the search for extra-solar system planets since the first discovery of an exoplanet surround a main sequence star was made in 1995 by Michel Mayor and Didier Queloz. Within months, Marcy and his team had not only confirmed this result but detected numerous other exoplanets. Seventy of the first one hundred exoplanets were discovered by Marcy's team, including the firs exoplanet located as far away from its star as Jupiter is to the Sun, and the first exoplanet discovered by observing its transit of its host star, a technique that will be used by JWST to explore the atmosphere of exoplanets to search for bio signatures. Marcy was then a Co-PI on the Kepler Mission, which discovered over 4000 exoplanets. For their pioneering work in the creation of this new field Marcy and Mayor shared the international Shaw Prize in 2005. More recently Marcy has turned his attention to methods to probe for intelligent life in the Universe, first as a PI on the Breakthrough Listen Project, and more recently exploring novel methods, including optical techniques to probe for possible signals of intelligence elsewhere. We discussed all of these exciting topics, as well as Geoff's own origins as a scientist in a thoughtful and fascinating discussion. He has become well known not just as a world renown scientist, but as one of the best communicators of astronomy there is. Our discussion will give a whole new dimension to your thinking about that age-old question: Are we alone in the Universe?

Andy Knoll: The First Four Billion Years of Life on Earth
Andy Knoll is a Renaissance Scientist. He is a geologist, paleobiologist, and geochemist and has applied key ideas from chemistry, biology, physiology and more to understanding the key developments associated with life on Earth—both how geology and chemistry have impacted on life, and vice versa. He has made ground breaking contributions to the understanding of almost every phase of life, from early Pre-Cambrian single cell life, to the emergence of more complex lifeforms, to mass extinctions. His group was the first to demonstrate that the rapid rise of CO2 was probably responsible for the last great extinction on Earth, a subject of some relevance today. For his work he most recently won the Royal Swedish Academy of Sciences Crafoord Prize in Geosciences… the equivalent of the Nobel Prize in that field. But more than all of this, Andy is a wonderful teacher and human being, and a great communicator . He has written numerous books on the history of life on Earth, and we discussed his most recent book, "A Brief History of Earth: Four Billion Years in Eight Chapters" in this podcast, along with his own origins and evolution as a scientist. The discussion was so fascinating that we went overtime during our first session and had to continue the next day. Our discussion will forever change your perspective on our planet, and our place within it. Enjoy.

Charles Murray: On Human Diversity
After writing the book, The Bell Curve, Charles Murray became a controversial figure in the US Social Science scene, and was much maligned in the public arena. His work has been misinterpreted as being racist and sexist, and at Middlebury College students forcibly stopped his guest lecture and rioted. As often the case with stereotypes, Murray is instead a thoughtful scholar who has tried to base his social science research on data from empirical science, something that should be standard, but isn't. I wanted to discuss his most recent book, Human Diversity, with him. It is far from controversial, and instead is a clear effort to explain often complex genetic concepts in a popular format. He makes it clear that he focuses on only well understood and well accepted concepts, and the discussion we had was instructive and enjoyable. He is a delightful and thoughtful individual and I believe that comes out in our dialogue. I know from experience, as I indicated at the beginning of our discussion, that many people will condemn the discussion without listening to it, just as they condemn his writing without reading it. But if you take the time, I think you will be pleasantly surprised, as well as learning some new things about the world. One of the purposes of The Origins Podcast is to connect science and culture, and Murray connects hard science with social science issues in a refreshingly honest and detailed way. Indeed, if all social scientists and policy makers took his approach, the overall tenor of popular discussion would improve, I believe. And while Murray and I do not share political views on a number of issues, thoughtful discussion is far preferred to blanket cancellation and denunciation or a refusal to even engage. Again, that, I hope, is a hallmark of the podcast. I hope you enjoy the discussion as much as I did. Get full access to Critical Mass at lawrencekrauss.substack.com/subscribe

(Audio) John Mather: From the Big Bang to Searching for Life
John Mather is an astrophysicist at NASA who has been involved in important space missions to probe our fundamental understanding of the Universe for over four decades. He helped lead the design and deployment of the Cosmic Background Explorer Satellite (COBE), which launched in 1989 to probe the cosmic microwave background radiation from the Big Bang with a precision that could not be obtained from terrestrial experiments because of absorption of radiation by the atmosphere. The experiments on COBE, and its successor missions WMAP and PLANCK, literally have turned cosmology from an art to a science, allowing the precise measurement of cosmological observables that previously were either not measured at all or only measured to within a factor of two. This has led to a golden age of cosmology, where theories of the early universe can now be compared directly to observation. John directed the building of the Far Infrared Absolute Spectrophotometer (FIRAS) on COBE which was able to show that the cosmic microwave background radiation was indeed an almost perfect 'black body' spectrum associated with a very well defined temperature of the Universe at a time of about 300,000 years after the big bang. Indeed, no terrestrial experiment has ever produced such an accurate black body spectrum, which was one of the fundamental predictions that helped develop quantum mechanics early in the 20th century. For his work on COBE, John shared the Nobel Prize with George Smoot. But John didn't rest on his laurels, for several decades after COBE John helped lead the design and development of the James Webb Space Telescope, which recently launched and will probe both the very early universe and also extra solar planets, possibly helping us discover evidence for life elsewhere in the Universe. John and I talked about his origins in science, the science he has accomplished, and what his future plans are in a discussion that will help provide a valuable perspective for anyone on the current status of cosmology and astrophysics, as well as what we might learn in the future. The ad-free video is available for all paid subscribers to Critical Mass in an adjoining post..

Origins Podcast with Michael Shellenberger: From Apocalypse Never to Running for Governor
I was very happy to have the chance to speak to Michael Shellenberger some time ago, after his book Apocalypse Never appeared. Having written my book, The Physics of Climate Change, I was intrigued by his take on the fact that climate change is not an existential threat. Once I read his book, I realized we agreed on many things, with perhaps the differences being on emphasize rather than substance. Nevertheless, we did have some disagreements, and we had a very spirited, and I hope respectful, discussion about climate change and its implications, but also on the other issues that need to be addressed and which climate change activists may be exacerbating because of their unique focus on this issue. The need to address important infrastructure issues in Africa and elsewhere in order to bring people up from poverty and also to help insulate them, or at least allow them to adapt to climate change is of great importance. Also, one of his central issues, the need for Nuclear Power, is an important issue, and I agree completely with Michael that we should not be closing down nuclear power plants, nor interfering with the construction of new plants. I don't see Nuclear Power alone as a panacea, however. While perhaps largely due to the current burden of regulation, nuclear power plants are expensive and time consuming to build, and I think that they are just one component of what needs to be a many-pronged effort to address climate change and other global challenges. Michael is incredibly passionate about his view of the crucial pressing challenges we face, and any categorization of him as liberal, conservative, libertarian, or climate denier, is false. He is a thoughtful humanist, and I found the discussion with him to be enlightening, as well as provocative, and I learned a lot in the process. That is the best kind of discussion, after all. After doing 2.5 hours together a year or so we sat together again (on zoom) for another discussion in the midst of his current run for California Governor. This gave us a chance to reconnect, and also talk about a different, new set of issues more relevant to that race, and to current problems facing the country.
