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!

On Thursday, June 18, 2026, we will meet in the 700N Conference Room at 700 N Hurstbourne Pkwy for a special Louisville .NET Meetup as we host **Microsoft Build //localhost:louisville**. Doors open at 6:00 p.m., and the presentation will begin promptly at 6:30 p.m. TEKsystems will provide food, so please RSVP to help us plan appropriately. The session will also be streamed at **[https://twitch.tv/TaleLearnCode](https://twitch.tv/TaleLearnCode)**. This month, we’ll dive into the most important announcements from **Microsoft Build 2026**. Chad Green will present a curated, developer‑focused walkthrough of the new capabilities across .NET, Azure, AI, developer tooling, and platform updates. We’ll explore what these announcements mean for architects and developers, how they fit into real‑world solutions, and which changes you can start applying immediately in your projects. And then, Rob Richardson will present: ### **GitOps: Easy Deploy and Even Easier Rollback** GitOps isn't just for containers. The methodology of deploying from a build is now baked into our culture. Take it a touch farther with infrastructure as code and a few extra techniques, and you can reliably deploy to any platform: cloud, on-prem, container, PaaS, and more. Join us as we learn the methodology of GitOps, the critical pieces you need in place, and the elegance of rollbacks with GitOps. You'll leave with a working repo of deployment techniques that doesn't consume any paid tools or container-specific techniques. **Important:** To participate fully, please RSVP in **both** places: * **Louisville .NET Meetup** (this page) * **Microsoft Build //localhost:louisville registration**: [https://developer.microsoft.com/en-us/reactor/events/27112/](https://developer.microsoft.com/en-us/reactor/events/27112/) After the session, we’ll head to Brick House Tavern to continue the conversation over food and drinks.

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. Please RSVP via [Microsoft Build //localhost:columbus | Microsoft Reactor](https://developer.microsoft.com/en-us/reactor/events/27247/).

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
