[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).

Regularly scheduled walk to see birds and sights.

Trivia!! Trivia starts promptly at 7, come earlier to get set up 630-645. Clear Sky's Meadery. 15201 Display Ct, Rockville, MD 20850

This regularly scheduled Thursday night run meets at the head of the Anacostia NE Branch trailhead. Meet at 6:30 pm for introductions and to decide what distance, time, or interval everyone's running. We hit the pavement by 6:45 pm. This is a time-based run, usually 30 minutes out-and-back. For many it's about a 5k or more. Runners of all abilities welcome! This is usually considered an 'easy' run. There is usually a group doing run-walk intervals, which is a great option especially for those just coming back to running.

Ready to tackle those classic books you’ve always meant to read (or reread)? Join DC Explorers and the I Should Read That, book club. We are launching a new, open book club dedicated to the classics, and everyone is welcome—whether you read these decades ago or are diving in for the very first time! Our first meetup is Friday, June 19th to discuss **Jules Verne’s** timeless adventure, **Journey to the Centre of the Earth.** We are **ONLY** discussing **chapters 1-15**. So no spoilers please. We'll always keep a relaxed pace of about 70–100 pages per week so there is plenty of time to enjoy the story before we gather over coffee, tea, or wine. **Location:** Busboys and Poets, 235 Carroll Avenue, Takoma Park **RSVP Deadline:** Wednesday, June 17th (so we can give the venue an accurate headcount) Logistics for the Meetup **Venue courtesy:** Please start a tab at the bar for any food or refreshments. We kindly ask that everyone purchase at least one beverage (coffee, smoothie, wine, etc.) to thank our hosts for providing the meeting space. **The Book Edition:** Warning: Because there are many heavily altered translations of this book, we highly recommend purchasing the Oxford World's Classics edition. It features the complete 45 chapters so we can all stay on the same page! You can order the book from our host Busboys and Poets [at this link.](https://bookshop.org/p/books/the-extraordinary-journeys-journey-to-the-centre-of-the-earth-jules-verne/1aafdcac17641bfe?ean=9780199538072&next=t) RSVP to reserve your spot, and feel free to ask questions. Your RSVP helps our host plan for space to accommodate everyone. Can't wait to read with you!

Every Sunday afternoon before church, one of the Covenant Life Church prophetess' hosts a prophetic training class that activates participants in the Gifts of the Holy Spirit. During this class, participants will be provided opportunity to be taught how to use the Gifts of the Holy Spirit and will have opportunity to ask questions and talk with someone who has been used in the Gifts during ministry. Teaching is provided on the gifts with emphasis on the Gift of the Prophecy. A combination of lecture and experiential learning is employed to teach, guide and instruct the participants. Everyone is welcome, all classes are free. Childcare is not provided.

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.

Cheers Nerdizens, Hope everyone's well. So as luck would have it, I'll hopefully be in DC Saturday, June 20th, to help celebrate and bid farewell to EveryDayPeople DC. My compadre Reg has made the difficult decision to close the place down. As such, Saturday will be there final day open. Reg is a good man who's been getting me slightly inebriated since I moved to DC back in the early 2000's lol. I was there when he first opened EveryDayPeople DC so it's only fitting I celebrate the brother as he closes shop and ventures on to other endeavors. If you enjoy good vibes, cool staff, great DJs, dope HipHop music and a drink or two, then make your way down to U. St and help me salute and pay respect to Reg and EveryDayPeople DC.

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!

I am finally scheduling the astronomy outing! Join us in attending the June "Exploring the Sky" event, a joint program between the National Capital Astronomers and the National Park Service. We will talk, eat snacks, look at items in the sky, and maybe play simple boardgames. This month, Mercury, Venus, Jupiter, and the Moon are all aligning near each other in the sky. We will probably see at least one planet, and if we are lucky we will even see these in a row. Come on time for the best chance to see this. The event may be canceled if the weather does not look accommodating. The location is the field by Picnic Grove #13 off of Glover Road, and can be reached by either public transportation plus walking or by coming by car as there is a parking lot, there. This link is the easiest way to find it: https://maps.app.goo.gl/BPrLLp8F4u2tjiTd7

The Group gathers in the parking lot between 6:00 AM and 6:30 AM to catch the sunrise over the Potomac River.

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.

Welcome, readers! Our June read is ***Endurance: Shackleton's Incredible*** ***Voyage*** **by Alfred Lansing.** A work of nonfiction, and one of the most astonishing survival stories in history, we follow Sir Ernest Shackleton and his crew after their ship is crushed by Antarctic ice. Stranded in one of the harshest environments on Earth, the men endure months of isolation, freezing temperatures, and near starvation—yet refuse to give up hope. Lansing brings their ordeal to life through vivid detail and firsthand accounts, capturing both the brutality of nature and the resilience of the human spirit. At its core, the story is a powerful testament to leadership, perseverance, and the unbreakable will to survive against impossible odds. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **all** **drinks must be purchased at the bar.** Happy reading! 📖
