Climate Change

On Tuesday, March 3, 5:30-7-30 pm, there will be a Washington Area Bicyclist Association Meetup taking place in Adams Morgan. There’ll be snacks and drinks for socializing before and after hearing from the guest speakers: WDC Councilmember Doni Crawford and Christina Whitehouse, Bike Lane Uprising founder from Chicago. Christina founded Bike Lane Uprising in Chicago in 2017 to make it easy for anyone to report bike lane obstructions. BLU has since gone national. Registration is required, to register, click at the following website: [https://waba.org/event/dc-03-03-26/](https://waba.org/event/dc-03-03-26/)

[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.

Please do not arrange to play earlier than the scheduled start time UNLESS you are able to stay till the end of the event, we do not want people leaving early and creating uneven numbers. Hello members, Tennis has become much more popular since the pandemic started and court space has been harder to come by. Following these simple rules will help everyone get the most out of MoCo Topspinners Meetup. • If you RSVP for an event, please attend that event or cancel at least two hours before the event starts. Members that no-show will receive one warning then will be benched (suspended) from events for two weeks. Three no-shows can result in a permanent ban. (No-shows create uneven numbers and prevent folks on the waitlist from playing. Please do your part to un-RSVP as soon as you know that you cannot attend an event.) • Members must have a way to communicate with organizers and hosts. This can be through the Meetup app messages or by providing other contact info. • Any member can ask a host or organizer to have their skill rated for event attendance purposes. You will not be allowed to participate in events higher than your NTRP rating. (We may try to limit numbers or have multiple events on a given day to accommodate players of different skill levels and also to help alleviate the court availability problem). • All members shall conduct good sportsmanship and be courteous to other members at all times. • Sexual harassment, racism, sexism or any kind of intolerance will not be tolerated and will result in the permanent ban from the group. • If member receives three warning infractions, the member will be suspended from the Meetup for a period of one month. If a member is suspended twice (six warnings), that member will be permanently banned and any membership dues will then be forfeited. • If you are scheduling to play with others outside of a MoCo Topspinners event, and you know that there is a MoCo Topspinners event scheduled for that day at that time, please try to use courts other than the courts where the event is scheduled, or move your time so that it does not conflict with the Topspinners event. For a list of complete rules and definitions you can see the MoCo Topspinners front page. If you have questions, don’t hesitate to contact us. We are hoping for a fun season but we may have to wait for courts and leave earlier than we are used to. Please be patient as we adjust to this new normal and try a few different things that will hopefully help the situation. Happy playing! If you would like to attend this event you must be a of minimum 3.0 level.

Twenty years ago, George Mason University professor Zachary Schrag published the definitive history of the Washington Metro: "The Great Society Subway". With the 50th anniversary of the system coming up at the end of March, TEDC founder Will Rice will make a presentation based on the book. Many elements and conflicts combined to create the Metrorail we now enjoy: a trust in big government projects; the battle over urban highways; the emerging D.C. home rule movement; Black-white relations; and the balance of city and suburban interests. Come learn more about it all! Also at the meeting: pick up your pre-ordered Metro 50 t-shirt (for new purchases, an order form is [here](https://transitenthusiastsdc.wordpress.com/wp-content/uploads/2026/01/t-shirt-order-form.pdf)). And hear the latest news on how we plan to celebrate the system's golden anniversary on March 27!

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.

Meeting Room 2b, Main Library Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. We desirere to cultivate a space where all questions are welcome and all members are treated with compassion and respect. All backgrounds are welcome.

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.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

Always an overachiever, David Bayer didn't settle for being Number Two in just about anything. Whether a runaway entrepreneurial success as a teenager, the leading online director for Ducati with over $70 million in sales, or as an early mid-life crisis overachiever with at least three wildly self-destructive behavioral addictions, whatever David did, he did it wholeheartedly. Not surprisingly then, when it came to facing his failures and determining his next course of action, David sought health and healing with the same full-strength effort he had previously used to bring about his own ruination. Seeking to learn from the best of the best, David's pursuit of tangible, practical, actual change from the mind and emotions, outward, brought a new passion--that of encouraging others to learn from his mistakes and to be able to strive after and achieve healing and success in their own lives. We are reading *A Changed Mind*, by David Bayer, and can't wait to enjoy the group discussion on **Wednesday, March 4, 2026, 6:30 pm**, at **True Food Kitchen, Easton Town Center**. Come join us!

Wouldn’t it be nice to find a way to overcome your feelings of anger so that you not only control them, but you no longer have the urge to lose your temper in the first place? And how about being able to shake off resentments, persistent annoyance, or even feelings of vengeance? We’d like to invite you to an event on how to overcome anger and resentment. We will show you why people have trouble controlling their temper and where resentment comes from. Flaring anger can ruin a meeting, a relationship, an opportunity, or just about any aspect of life. Worst of all, outbursts towards our family can create hurt that lingers throughout a lifetime. You want to have a civil conversation, and you’ve vowed that you wouldn’t lose your temper, but a few minutes later, the anger flares up. Maybe you’ve realized that being angry doesn’t get you what you want so you internalize it. Or maybe you avoid the knockdown, drag-out fights, but stewing in resentment is exhausting and takes an emotional toll. In this event we show you how to get to the root of your anger so that it stops being an issue to you. You’ll also learn why people harbor resentments and how to move on. Don't continue to struggle, make a difference in your life, and join us for this local event. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This Meetup is sponsored by your local Dianetics and Scientology Life Improvement Center.

Sleep in on Sundays. When you've had your fill of pajama-time, roll out and have some tasty brunch with your fellow Humanists!
