Interesting presentation on complexity in the universe.![]() 15th Annual Biard Lecture - Sean Carroll "Complexity in the Universe" Complexity in the Universe Sean Carroll (Johns Hopkins University and Santa Fe Institute) Wednesday, February 19, 2025 Held at the Mershon Auditorium, The Ohio State University A famous law of physics, the Second Law of Thermodynamics, states that the entropy of the universe increases over time. And entropy is supposed to be a measure of disorder or randomness. This raises an important question: how did we come to be? Biological organisms are exquisitely ordered and complex, not something we might expect to arise out of a universal tendency toward disorder. In this talk, I will show how simplicity/complexity is a distinct idea from order/disorder, and suggest how complexity can naturally develop between the Big Bang and today, before eventually fading away in the far future. Sean Carroll (https://www.preposterousuniverse.com/) is the Homewood Professor of Natural Philosophy at Johns Hopkins University and Fractal Faculty at the Santa Fe Institute. He received his Ph.D. in 1993 from Harvard University. His research focuses on the foundations of physics, including issues in quantum mechanics, spacetime, cosmology, and emergence. He is the author of several books, most recently The Biggest Ideas in the Universe, Vol. 2: Quanta and Fields. He has been awarded prizes and fellowships by the National Science Foundation, NASA, the Sloan Foundation, the Packard Foundation, the American Physical Society, the American Institute of Physics, the Royal Society of London, the Guggenheim Foundation, and the American Association for the Advancement of Science. He is the host of the weekly Mindscape podcast. |
Interesting presentation on the origins of different alphabets.![]() PSW 2511 Alphabet Histories | Johanna Drucker Alphabet Histories: The Origins of Letters from Antiquity to the Present Johanna Drucker Distinguished Research Professor UCLA The history of alphabetic writing from its origin to its modification and spread is now more or less well-mapped. And though many common misunderstandings about the identity and diversity of alphabetic script remain, paleographers, epigraphers, and archaeologists have established a solid foundation for historical knowledge of when, where, and by whom the alphabet was invented. Occasionally new discoveries, such as the incised clay objects recently unearthed in Syria, or the Wadi el-Hol inscriptions discovered in the 1990s, challenge older narratives. But though the development of the alphabet is sufficiently established, a systematic account of the historiography through which we came to know that history was not mapped comprehensively until the research on which this talk is based. First briefly sketching the origin of the alphabet, this talk traces various intellectual lineages from antiquity to the present, some now set aside, others still continuing, with an emphasis on technologies of knowledge production over several millennia. Attention to the materiality of information sources is an integral part of history of science and technology studies, but it has been less fully attended to in scholarship in the humanities. Using a constructivist approach to knowledge (based on the principle that what we know is a product of how we can know), this talk examines the material properties of textual, biblical, graphical, tabular, artefactual, archaeological, epigraphical and digital/forensic approaches to the evidence on which alphabet history is produced. The talk suggests that each phase of alphabet historiography be examined for its validity on its own terms, as a full explanation of the origins and development of script, even as the understanding of time scales and cultural processes of knowledge transmission have been through multiple paradigm shifts. Reflections on how the alphabet is conceived and understood have included mystical, magical, linguistic, pragmatic, and semiotic dimensions all of which continue to have some advocates into the present. The potency of letters is one of the touchstones of human history, not only in the empirical frame of an established record, but in the cultural imaginary where it is sustained. Long traditions fuel these beliefs and attention to their tenets provides an insight into the way knowledge attains legitimacy and asserts authority through various critical perspectives using different sources and types of evidence. The global hegemony of the alphabet is apparent in its use in the internationally networked communication systems. All alphabets in use today—Roman, Hebrew, Arabic, Cyrillic, those in the Indian sub-continent—derive from a single source, the proto-Canaanite script developed in the Ancient Near East in the 2nd millennium BCE by Semitic speakers. Their accomplishment was not the invention of writing—that already existed in cuneiform and hieroglyphic systems throughout the region—but the analysis of spoken language into significant sounds that could be represented by a limited set of signs. Astonishingly, those signs, adopted for a multitude of languages, graphically modified, are what undergird our contemporary global communications and information transmission. The implications of alphabetic hegemony are linked to the history of its origin and development, and the larger issues in characterization of the Semitic roots and territories are evident in current regional and global politics. Johanna Drucker is Distinguished Professor and Breslauer Professor Emerita, Department of Information Studies, UCLA. Drucker is internationally known for her work in the history of graphic design, typography, experimental poetry, fine art, and digital humanities. Recent work includes Visualization and Interpretation (MIT Press, 2020), and Iliazd: Meta-Biography of a Modernist (Johns Hopkins University Press 2020), Digital Humanities 101: An introduction to Digital Methods (Routledge, 2021). Her most recent publication, Inventing the Alphabet (University of Chicago Press, 2022), documents the intellectual history of knowledge about the invention and spread of the alphabet. Her work has been translated into Korean, Catalan, Chinese, Spanish, French, Hungarian, Danish and Portuguese. She received her BFA from California College of Arts and Crafts in 1973; MA in Visual Studies from University of California, Berkeley, in 1982, and her PhD from UC Berkeley in 1986. |

Presentation around James Webb Telescope.![]() PSW 2510 The James Webb Space Telescope | Robert Smith The James Webb Space Telescope: Key Moments in Its History From "Napkin" to Lagrange Point Robert W. Smith University of Alberta The James Webb Space Telescope (JWST) – a joint enterprise of NASA, the European Space Agency, and the Canadian Space Agency – is the most complex and in some ways the most powerful telescope ever built. And since its launch in 2021, JWST has produced a string of spectacular scientific results. JWST’s history, which includes a near-death experience at the hands of a U.S. congressional committee in 2011 when there was an effort to kill the project, raises a range of critical policy issues. This lecture will discuss several key moments in JWST’s history, and what these have to say not just about JWST and the future of space astronomy, but also about very large-scale scientific enterprises more broadly, projects of such a scale that we can reasonably refer to them as “megascience.” The lecture will discuss similarities and differences in the policy contexts for JWST, the Hubble Space Telescope, and the ill-fated Superconducting Supercollider which was cancelled just before serious planning got under way for JWST. Hubble, for example, exemplified (after serious initial problems) the successful management of increasing scale, which was central to the broader success of large-scale science in the twentieth century. Hubble demonstrated the ability of “science managers” and astronomers to operate successfully in – and to shape – the prevailing “political economy” of science. The lecture will consider how JWST may be seen in this regard, and some of the lessons its history may have for future large scale science missions. Robert W. Smith is a Professor of History at the University of Alberta. For many years before that he was a staff member of the US National Air and Space Museum. In addition, he has served as an advisor to the Organization of Economic Cooperation and Development, NASA, and the National Academy of Sciences, among others. Robert is an author of over 50 research papers, most of them as sole author; author or coauthor of five books; and co-editor of three volumes. Publications of his have been translated into French, Spanish, Italian and Chinese. Robert’s first book was The Expanding Universe: Astronomy’s ‘Great Debate’, 1900–1931, and he has continued to publish on early twentieth century astronomy and cosmology throughout his career. While he has also written extensively on nineteenth century astronomy, his chief research area is the history of space astronomy, and he has a particular interest in the emergence of space astronomy as “megascience.” His research on the prelaunch history of the Hubble Space Telescope is summarized in his book, The Space Telescope: A Study of NASA, Science, Technology and Politics, which also includes contributions by Paul Hanle, Robert Kargon, and Joseph N. Tatarewicz. For more than two decades he has been following the progress of the James Webb Space Telescope project, and he is working on a history of the telescope. Among other honors and awards, Robert was a Fellow at the National Humanities Center in the United States, held the Lindbergh Chair of Aerospace History at the Smithsonian Institution, and was the Sarton Lecturer for the History of Science Society at the American Association for the Advancement of Science. He has been awarded the American Astronomical Society’s Doggett Prize for Historical Astronomy, the History of Science Society’s Watson Davis Prize for The Space Telescope, and the Bunge Prize of the Gesellschaft Deutscher Chemiker and the Deutsche Bunsen-Gesellschaft für Physiklische Chemie for seminal contributions to the study of the history of scientific instruments. Robert earned a BSc at Queen Mary College, University of London, Part III of the Mathematics Tripos at the University of Cambridge, and a PhD in the History and Philosophy of Science, at Cambridge University. |

Here the author gives a fictional presentation describing how a Pharma treatment for autism resulted in the discovery of dormant vampire genes, and the program to explore their capabilities. He describes their biology and evolutionary origins in the guise of an investment sales pitch for resurrecting the species to take advantage of their mental talents. This serves as a general background for the setting of the book which is a First Contact novel set in the near future. The author is a PH.D. in Zoology and worked as a marine biologist, so he infuses a lot of hard science into his books. https://www.rifters.com/blindsight/vampires.htm |
Interesting presentation on detecting exoplanets via microlensing.![]() PSW 2512 Detecting Exoplanets by Gravitational Microlensing | David Bennett Detecting Exoplanets by Gravitational Microlensing Survey Gaps & Rogues David Bennett Senior Research Scientist NASA Goddard Space Flight Center Our current knowledge of exoplanets is dominated by planets that are very different from those in our own Solar System, primarily because the most prolific exoplanet detection methods are most sensitive to planets with short orbital periods or large masses. The gravitational microlensing method will fill this gap with sensitivity down to Mars-mass planets, with maximum sensitivity just beyond the snow line, where planet formation is thought to be most efficient. For this reason, NASA has selected an exoplanet microlensing survey as a core survey for the Nancy Grace Roman Space Telescope. The Roman Telescope will complete the statistical census of exoplanets started with the Kepler mission’s Galactic Bulge Time Domain Survey, which will be able to detect planets like those in our own Solar System (except Mercury). The Roman Telescope’s sensitivity will extend far beyond the orbital separation of the planets in our own Solar System’s and will be able to detect unbound (“rogue”) planets as well as orbitally bound ones. Ground-based microlensing surveys have already provided hints of what the Roman Telescope may find. The microlensing data thus far seems to contradict predictions of a sub-Saturn mass desert in the wide orbit exoplanet distribution. Even more surprising than this result is the recent discovery by the MOA microlensing survey that low-mass “rogue” planets appear to be more common than all known types of bound planets, although some of these “rogue” planets could be in very wide orbits around stars. This is a somewhat unexpected clue to aspects of the planet formation process as it is currently understood. This lecture will review the exoplanet microlensing discoveries to date, and explore how the Nancy Grace Roman Telescope’s exoplanet microlensing survey will add to the statistical census of exoplanets data on wide orbit and rogue planets that is needed to develop our understanding of planet formation. David Bennett is Senior Research Scientist at the NASA Goddard Space Flight Center and at the University of Maryland. He currently serves as the Science Principal Investigator (PI) for the Nancy Grace Roman Telescope Galactic Exoplanet Survey Project Infrastructure Team and as the US PI for the Microlensing Observations in Astrophysics (MOA) collaboration. Previously, David served as the PI for the Microlensing Planet Finder mission concept, which was combined with two similar mission concepts to create the Nancy Grace Roman Space Telescope (previouly called WFIRST). He served on the first NASA Exoplanet Analysis Group Executive Committee, and on every WFIRST and Roman Space Telescope science team since 2011. Before this work, David had postdoctoral positions in theoretical cosmology at Fermilab and at Princeton. David’s research has been primarily on microlensing and its use to study dark matter and, more recently, exoplanets. In graduate school he became intrigued by Bohdan Paczyński’s paper showing that a gravitational microlensing survey could confirm or deny the possibility that the Milky Way’s dark matter consists of objects ranging from planetary to stellar masses. He suggested this idea to Charles Alcock at Lawrence Livermore National Laboratory (LLNL) (in 1989!). The next year he joined Alcock to work on the first gravitational microlensing survey, which they called “MACHO” (for Massive Compact Halo Objects). MACHO proved to be quite successful: discovering the first microlensing event (in 1993!) Sun Hong Rhie in examining the result, had the remarkable insight that a short duration feature in the light curve of this event could be due to a planet. This led her to work out important aspects of gravitational microlensing theory, leading to a seminal 1996 paper (with David Bennett) showing that microlensing was sensitive to very low-mass planets. Rhie and Bennett realized that a space-based microlensing survey would be needed to realize the full potential of exoplanet microlensing, leading them to propose the Galactic Exoplanet Survey Telescope (GEST) to NASA in 2000, and to a revised proposal for GEST, including the cosmology programs that are now a major focus of the Nancy Grace Roman Space Telescope. Much of David’s subsequent research has focused on further development of the space-based exoplanet microlensing survey methods, with recent emphasis on methods to determine the masses and distances of exoplanetary microlensing systems. David is an author of more than 400 scientific publications. David earned a BS in Mathematics at Case Western Reserve University and a PhD in Physics at Stanford University. |

Grinding grains came later - along with it, dental deterioration/decay. |
