Let's meet up for Pizza and Ping Pong at Comet in DC Fun event to play ping pong and eat some good pizza. WE can play some games too Parking lot in the back and street parking available Guests must be over 50 This is a non reservation event. It's time to RSVP for a fun evening.

Socrates Café meets on the first Saturday of each month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

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.

**This talk has completely sold out in advance and no door tickets will be available. It also is being staged at Penn Social in DC on March 17th, and tickets remain available then.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Ireland’s Fight for Freedom,”** with Kevin Matthews, assistant professor of history at George Mason University and former London correspondent for Vatican Radio reporting on British and Irish news. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom) .] After centuries of struggle, Irish men and women won their freedom from Great Britain after waging a war that set the pattern for all other independence struggles of the 20th century. But there was a price—the partition of their country, a split setting the stage for the Northern Ireland “Troubles” that didn’t end until 1998. Gain a deeper understanding of Ireland and its history with Professor Kevin Matthews, a historian and frequent Smithsonian Associates speaker who had served as a journalist covering the last stages of the Troubles in Ireland in the early and mid 1990s. He’ll discuss in depth how the Irish won independence in a two-year war between 1919 and 1921, covering topics as the role women played in the conflict, the life and tactics of the revolutionary leader Michael Collins, and the Irish development of “urban guerilla warfare” using small, highly mobile armed units called “flying columns.” Most important, this talk will examine how the conflict between Irish nationalists and Irish unionists led to Ireland’s division and later conflict. From the Easter Rising to the Good Friday Agreement, from Bloody Sunday to Brexit, this conflict has never quite gone away. As the Irish poet, William Butler Yeats once wrote: Now and in time to be, Wherever green is worn, Are changed, changed utterly: A terrible beauty is born. Professor Matthews will explore how the Irish fought to a standstill what was then the mightiest empire in the world and how, more than he could have known, Yeats’ prediction still rings true today. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Members of the Irish Republican Army’s West Connemara Flying Column in 1921.
