29th Parallel Coffee at 10:30AM and walk around Burke Lake Park at 11:30AM
We'll check out 29th Parallel Coffee in Fairfax Station. We plan to grab a coffee and head to Burke Lake Park and walk around the lake (weather permitting). There are a couple of parking areas at the park. I marked the parking we're planning to meet at the park. We hope to start the walk around 11:30AM. If you're a Fairfax County resident (with an ID), parking is free, otherwise they charge for parking.
Please have a picture profile so we can recognize you in the meetup.
What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation
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!

A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Here’s the gist:
We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat.
Most importantly, we’re excited to meet you!
Catch you on Saturday,
Diego / Ian / Cayden / Nate / Otasha / Lia / An

MoCoLUG Meeting
This will be our kick-off meeting. Mostly, this is to get to know one another, and to figure out what everyone is looking for with the group and meetings. Newcomers to Linux and Free Software are always welcome, so please feel free to spread the word!
Note, the room I was hoping to use in Wheaton is in extremely high demand, so this will be at the Silver Spring Library (Brigadier General Charles E. McGee Library), in Small Room 2. Unfortunately, parking is ***not*** free on Saturdays, and is $1.25/hour.
Shakespeare in the Parks. As You Like It
Love, disguise, and redemption collide in Shakespeare’s As You Like It. Driven from court by sibling rivalry and ruthless ambition, Orlando and Rosalind escape into the Forest of Arden, where identities blur and hearts awaken. Disguised as a young man, Rosalind playfully tests Orlando’s devotion, turning exile into a journey of love and self-discovery.
Witty, romantic, and full of heart, As You Like It celebrates love in all its unexpected forms. Bring a lawn chair, and a picnic and enjoy the bard under the stars. Restrooms and water fountain will be available.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

HOW TO BE A BETTER COMMUNICATOR - Free, in-person meeting
Communication is everything in life!
You are only as successful as your ability to communicate.
\- What if you could confidently talk to anyone?
\- What if you had the ability to calmly control every conversation?
\- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence?
You can!
The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.
Hosted by the Church of Scientology of Central Ohio
