Title: What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation of Scientific Discovery Date: June 20 2026 Noon - 14:00 EDT Summary: Our collective knowledge infrastructure — the textbooks, professional training resources, and literature syntheses that define what professionals across disciplines believe to be true — is quietly accruing a structural liability. Compounded confirmation bias, stacked citation-by-citation into the foundations of formal knowledge, means that breakthroughs can take decades to reach the classrooms, clinical workflows, and decision-making frameworks where they matter most. Meanwhile, the deepest friction is rarely acknowledged: before any field can build meaningful consensus on "why" or "how" a phenomenon occurs, it must first establish honest, consolidated agreement on "what" has actually been observed. That prior step is routinely skipped, assumed, or fragmented across siloed literatures that never cross-pollinate. This talk introduces a framework called "Knowledge Aggregation" — with two distinct but complementary ambitions. The first is descriptive transparency: algorithmically mapping what has been said, measured, and documented across a problem space, without imposing causal interpretation or narrative. The second traces the boundary between empirical observation and explanatory claim, building systems that can separate the "what" from the "why/how" — because consensus on mechanism cannot be meaningfully constructed until consensus on phenomenon is first established. Both ambitions are now within reach. By composing tools already at our disposal — large language models, classical NLP pipelines, public data repositories, and engineering-grade automation frameworks — it becomes possible to model knowledge itself, rather than merely imitate individual experts. One concrete expression of this is automating the writing of living textbooks: compressing the lag from bleeding-edge discovery, through replicated evidence, all the way to professional training resources. But the deeper aspiration reaches further — toward automating the discovery of scientific insights that have never previously been conceived, by systematically surfacing hypothesis combinations that no single siloed researcher would have had the cross-disciplinary vantage point to even ask. Drawing on ongoing systems biology and computational research — with ME/CFS research demoed as a use case for what siloed, fragmented knowledge infrastructure costs in practice — this talk maps the conceptual architecture, the real-world friction, and the data science toolkit for building it. Speaker: As a systems biologist at heart, Sam specializes his biomedical research on interactions and connections in biology - rather than just one domain of expertise. He wears many hats and collects skill sets across disciplines, with degree studies and industry experience acquired across Chemical Engineering (BSc), Bioinformatics (MSc), Systems and Synthetic Biology (M2), Biomedical Sciences (MSc), and beyond. Even more important to him than niches or fields of work, comes down to the synergistic approaches that allow us to move beyond reductionism. The notion that a question can only allow for one answer, is inherently reductionist. By resisting many norms in science and engineering which can get overly reductive, his current role as Principal Investigator of Research for DMV Petri Dish (501(c)(3) non-profit local to the DMV region) embraces computational frameworks that aide scale-up and automation - not only around the processes which already exist with established workflows, but also taking a keen interest in attempting and accomplishing ambitions which have never been perceived to be possible previously. Sam carries a passion for the synergy of computational biology - fused with wet lab validation. This way, one can build a beautiful knowledge base in the theoretical sense, and then test to see if said computational prediction might actually be able to stand in the real world with wet lab validation. Translational modeling starts to become possible once biological experiment design can be iteratively looped alongside computational model design, optimization, and analysis - empowering the design of a better wet lab experiment, followed by a better computational model, back and forth until science is done!

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Owl Wisdom,”** an introduction to the biology, habits, and conservation of various owl species in our region and beyond, with Steve Sheffield, professor of biology at Bowie State University, curator of mammals and birds for the Natural History Society of Maryland, and president of the Maryland Ornithological Society. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-owl-wisdom](https://events.ticketleap.com/tickets/profsandpints/dc-owl-wisdom) .] Who wants to learn about owls? If you are fascinated by these hunters of the night, you’ll love spending an evening with Steve Sheffield, a biologist who extensively studies owls and works to conserve them. He’ll start by covering the different types of owls in our region and elsewhere, and the ways in which their bodies and their sizes represent physical adaptations to their environment. He’ll especially focus on the owl species of the United States and Canada, describing their biology, ranges, preferred habitat and prey, behavior, and vocalizations. You’ll learn how and why field biologists study owls and how owl researchers from around the world assemble periodically to discuss their work. We’ll consider owls' value to ecosystems and, especially, humans and human-dominated landscapes where they serve as especially efficient killers of rodents and other crop-harming pests. Dr. Sheffield will talk about the many years he has spent researching owls, with much of his work focused on their exposure to environmental contaminants and how they’re affected. Being top predators, owls serve as sensitive bioindicators of contamination throughout the food chain. Much like canaries in coal mines, they function as an early warning system alerting us to potentially dangerous levels of toxicity. We don’t just study them for their own good, but ours as well. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Burrowing owls in Florida (Photo by travelingwayoflife / Creative Commons).

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Can Artificial Intelligence ‘See’?”** A look at how humans and artificial intelligence systems interpret the visual world in fundamentally different ways, with Arryn Robbins, assistant professor of psychology at the University of Richmond and cognitive scientist who researches visual attention, perception, and category learning. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-can-AI-see](https://events.ticketleap.com/tickets/profsandpints/nv-can-AI-see) .] Artificial intelligence can now identify faces, categorize objects, describe scenes, and outperform humans on certain visual tasks. But does AI actually “see” the world the way that people do? Or does it arrive at correct answers using representations that differ markedly from human perception? Join Arryn Robbins of the University of Richmond for a fascinating exploration of how humans and AI construct meaning from visual information and a look at comparisons between human perception and AI that reveal just how dynamic and context-dependent our own visual systems really are. Dr. Robbins, who previously has given excellent Profs and Pints talks on flaws and biases in human visual perception, will draw from research in cognitive science, visual perception, and AI vision systems. She’ll explain how human perception is not merely a simple recording of the world, but an active process shaped by expectations, context, goals, and recent experience. You’ll learn how humans form flexible mental representations that allow us to recognize objects across changing environments and conditions, and why those representations continuously adapt as we interact with the world. Many AI systems, by contrast, learn visual categories through statistical patterns in data. They can produce impressive results, but sometimes they also produce strange and unexpected failures, and sometimes they classify images in ways that seem strange to us. Dr. Robbins will discuss what these differences reveal about the nature of perception itself, and why the mismatch between human and AI representations matters for technologies like self-driving cars, medical imaging, facial recognition, and automated surveillance. Important for anyone trying to understand the rapidly growing role of AI in daily life, this talk will explore one of the biggest questions in cognitive science and artificial intelligence: What does it actually mean to “see” and understand the world?
