Vernon Trail alongside the scenic Potomac River. LOCATION: Meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse). Link to location on map: http://i.imgur.com/3yN0lwN.jpg NOTES: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms. Let's meet at 6:50 PM, leaving by 7:00 PM. We will do 50 minutes, so 25 minutes out and 25 minutes back. You're welcome to do more if you'd like. Just before the run we decide whether we'll go NORTH (DC) or SOUTH (Old Town) on the trail. Once we're done, we meet back up at the Crystal City Water Park area. After the run please feel free to hangout and socialize with the group or join us at National Landing Water Park for a beverage and/or food. https://g.co/kgs/AErMQZ All paces are welcome! We run by time, not speed so bring a watch to monitor your time and turn around at the halfway time point. If you need to run/walk, that's ok! We average anywhere between 7-13 minute/per mile pace. First Time? Start out slow to find someone around your pace. The different paces tend to automatically gather, so you won't be alone! Metro: Crystal City on Blue/Yellow lines, 2 blocks from metro exit. Parking: There is plenty of paid parking options (parking garages, street parking, or parking lots) in the area on Crystal Drive or Long Bridge Park. Post-Run: A lot of times we have a little social outing after the run. You can bring a change of clothes if you'd like (though most people just go as is). We'll finish up the run, meet back at the Water Park, pick up our wallets and walk to wherever we decided to go for a beverage and/or food. If you have a suggestion for a place to check out, let us know!

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!

It's my birthday! Let's craft. We'll be meeting at Quill and Crumbs at the Shakespeare Folger Library in SE. The Shakespeare Folger Library is about 3 blocks from the Capitol South metro. Head up First as you get out of the station, pass the Library of Congress and the Capitol, turn right on East Capitol, and the Folger is on the right. The entrance is around the side, not through the front of the building. Head upstairs to the cafe and we'll be at the tables at the back. Bring your own cross stitch, knitting, crochet, or other portable craft.

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

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle. **Optional topic for this meetup: Where is everybody?** In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox. One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread. Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for. **Questions to wrestle with:** * Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving? * Where do you bet the filter sits, behind us or ahead of us, and why? * If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming? * Two principles pull opposite ways here. The principle of mediocrity (the Copernican principle, Sagan's "no privileged place in the universe") says we are ordinary, so what happened on Earth probably happened everywhere, which makes the silence scream louder. The anthropic principle says of course we find ourselves somewhere life was possible, since we could not observe anything else, so our being here may say almost nothing about how common life is. Which lens do you trust, and does the silence still demand an answer once you account for observer selection? * And if we did confirm life out there and had to accept we are not special, what would that do to belief in a higher power, and would shedding (or keeping) that belief help or hurt our odds of pulling together as one species? * Does any of this change how you live, or how humanity should be spending its time and money right now? As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
