[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Trump, Your Rights, and Resistance,”** an overview of the legal landscape in the District of Columbia just over one year into Donald Trump’s second administration, with Scott Michelman, legal director of the ACLU of D.C. and lecturer on law and Shikes Fellow in Civil Liberties and Civil Rights at Harvard Law School. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-trump-rights-resistance](https://events.ticketleap.com/tickets/profsandpints/dc-trump-rights-resistance) ] Our nation looks a lot different just over a year after President Trump took office in January 2025. What has actually happened—and what does it mean for our rights? Get an informed breakdown on the civil rights and civil liberties issues that have defined the period since Trump's second inauguration with Scott Michelman, a legal scholar who last January gave an excellent talk on the legal guardrails potentially checking Trump’s actions. He’ll discuss what has been happening with immigration policy, criminal justice reform, domestic military deployment, discrimination, and threats to free speech. He’ll identify troubling patterns, explain where advocates have successfully pushed back in the courts, and outline the unresolved concerns ahead. The talk will also explore what individuals can do next, from understanding their rights to participating in elections that will shape the future of this administration and our country. (Door: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: The October 18, 2025 “No Kings Day” protest in Washington D.C.

Title: What Is Space Density? From Medium Ontology to the Spacetime Constant K Date: March 8 2026 10:00 am - Noon EDT Abstract: Spacetime plays an active role in gravity, wave propagation, and quantum behavior, yet physics rarely treats it as a physical medium with intrinsic properties such as density or inertia. This missing layer creates a major conceptual gap—especially when interpreting large-scale gravitational anomalies that are often attributed to dark matter. In this talk, Lynn will propose a clear conceptual framework for what it means for spacetime itself to possess a density-like property, and Lynn will explain why Unified Field Theory (UFT) naturally encodes this property through the constant K, called the spacetime background inertial intensity constant. Lynn will introduce a space-density constant μₛ as a universal property of space itself—independent of matter, energy density, or gravitational sourcing. However, μₛ cannot be inserted directly into field equations, because it belongs to the ontological level: it describes what space is, not how spacetime responds. To influence dynamics, μₛ must be expressed geometrically. This leads naturally to K, which carries the same physical meaning but operates at the level required by geometric field dynamics. This is a change in representation—not the addition of new physics. This approach provides an alternative way to interpret dark-matter-like effects. Instead of requiring unseen particles, gravitational anomalies can be viewed as consequences of spacetime’s intrinsic rigidity and its global, cumulative response in large coherent systems such as disk galaxies. In local, weak-field environments, standard Newtonian and relativistic gravity remains an effective approximation. The goal of the talk is not to present a final empirical model, but to clarify the physical meaning of spacetime constants and open discussion between UFT and mainstream theoretical physics. Keywords: Spacetime ontology; space density; intrinsic spacetime properties; Unified Field Theory (UFT); spacetime background constant K; geometric response; gravitational coupling; dark-matter-like phenomena Brief Biography Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.

Winter’s on the wane and signs of spring are popping up, making now a perfect time to appreciate the intermingling of the best of both seasons. Experience the beauty of bare tree architecture and the welcome sight of early bloomers on a stroll abounding with sensory delight at Green Spring Gardens, a local treasure. Tuning in with our senses, we’ll combine slow strolling with attentive pauses to deepen our connection with nature. Green Spring offers space for quiet enjoyment throughout the seasons, and is particularly noted for its collection of dozens of cultivated varieties of witch hazels of many colors. Their unusual flowers are among the earliest to open, often blooming amidst snow and ice, and they are in bloom now. There’s pussy willow (pictured) too. The health benefits of slowing down in quiet company among trees and plants with senses alert and aware are scientifically documented, but the best way to understand these benefits is to experience them yourself, preferably on a regular basis. IMPORTANT! The size of the group is limited! Please be sure to update your status asap on either the “going” or “wait list” if you sign up and find you can’t make it! Walking under 2 miles is mostly on natural, somewhat uneven surfaces, with a few short hills. Wear good walking shoes, a hat and sunscreen, and bring water (or tea) to drink. Park and meet near the open gate on Witch Hazel Rd at Green Spring Gardens 38.82428° N, 77.15808° W 4500-4504 Witch Hazel Rd, Alexandria, VA Please arrive by 8:45 to sign the required SCPRO waiver.

This Saturday I've invited Sandy F. to help co-host this event. She is an experienced birder with years of experience in finding and identifying birds in our area. The Group gathers in the parking lot between 6:00 AM and 6:30 AM to catch the sunrise over the Potomac River. Google Maps: [https://maps.app.goo.gl/hCUuoxUPKhRbLLZn9](https://maps.app.goo.gl/hCUuoxUPKhRbLLZn9) Dyke Marsh Wildlife Preserve is known as a top regional birding spot, over **300 species** have been recorded here, including nesting bald eagles and ospreys. Bring your longest telephoto lens and binoculars. I can help you with camera settings so you can capture sharper images of both perched birds and birds in flight. I randomly drop by this afternoon before the snow and saw many amazing birds. I posted a few already. Note: I set the meetup for 6:30am to capture the sunrise. It's supposed to be partly cloudy which should make for amazing skies. I suggest you arrive at 6:00 AM to capture the glow of twilight hour. It is thrilling to capture the amazing orange and red colors that are only available at that time in the morning. Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos. Bring water, comfortable shoes, a tripod, fully charged batteries, and empty memory cards...

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.
