Aquariums

Time for a Happy Hour in Arlington, VA; 6:00 to 9:00 PM Come meet old Dive Buddies, new Dive Buddies, or chat about dive trips and diving. I'll have some information about trips to Bonaire, Belize, and the Cayman Islands as well as a couple of Florida Trips and Lake Phoenix. Come join the fun. Haven't gotten certified yet? We can help connect you with the right shop or instructor. The Brass Rabbit has graciously reserved high tops in the bar area so it will be easy to mix and mingle. They also have a great food and a good selection of libations. Look for the dive flag or safety sausage. The Brass Rabbit is easily accessible from the **Clarendon Metro** station. Looking forward to seeing everyone there. Its been a while.

It is supposed to be 60 degrees Thursday. Let’s take advantage with a walk at Brookside Gardens. We will meet to the right facing the visitors center. If anyone is interested we can go to lunch afterwards.

Please join members of the the Arlington Running Club each Thursday night at 6:30 PM for our weekly Run 'n' Quaff at Astro Beer Hall located at 4001 Campbell Avenue, Arlington Virginia 22206 in the Shirlington neighborhood of Arlington, Virginia. We are a laid back group of runners that enjoys running a 5-K (3.1 mile) course each week followed the quaffing of cold refreshing adult beverages. We have runners of all abilities from the beginning runner / walker up through marathoners and ultra runners. Our age group spans from early twenties through late seventies and all ages in between. There is someone your age range / someone your skill level at our weekly meetups. No check-ins, waiver forms, or administrivia. No rules, just right.

• What we'll do Learn how to take great pictures BEFORE you go on that expensive trip! And we will teach you how to use your camera IN THE FIELD, not in a classroom! Join our standard Monuments and Memorials workshop, offered Wednesdays and Saturdays, in which the instructor takes you to some of DC’s most popular attractions: White House, Lafayette Park, the Einstein, Lincoln, Korea, and Vietnam Three Servicemen Memorials, and finally to Union Station, where you learn to make all the moving people DISAPPEAR! Remember, it was Confucius who said: "I hear and I forget. I see and I remember. I do, and I understand." At Washington Photo Safari, we help you "do " and understand! That is why our motto is "See. Click. Learn." This $71 Safari (a 20% discount from the regular $89 price) begins with a 45-minute travel photography orientation, giving you basic tips in composition, F-stops and shutter speeds, portraiture, and interior photography. While you are taking pictures, you receive hands-on guidance on how to make those images even better! Advanced and smartphone photographers will appreciate the instructor’s extensive knowledge of the best camera angles in DC. This is suggested as a preliminary course before taking special safaris. Open to any photographers at any skill level with any camera, phone, or tablet. Transportation from site to site is provided by the instructor. • What to bring camera and all lenses • Important to know travel, architectural, portrait and street photography techniques

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.
