**Gold Mine and Great Falls Overlook. A Moderate 6.5 Mile Hike** This hike features the remnants of a quirky gold mine and the classic overlook of Great Falls. The mine was established by a Union soldier who was stationed along the Maryland side of the Potomac River near Great Falls during the Civil War. He noticed a glint of gold and after the war, he returned to the area, bought some farmland, and started mining for gold. Eventually, 30 small mines were opened by various prospectors. One of the largest mines was the Maryland Mine. A total of 5,000 ounces of gold were produced by the mines in the area, worth about $10,000,000 in today's money. Today, little remain of these mines, but there is a loop trail that passes by one of them. The hike starts near Old Angler’s Inn, passes by the mine remains, then goes down to the classic overlook of Great Falls before returning to the woods and hiking back on trails with splendid views of the Potomac River. Bring a snack or lunch to enjoy at one of the overlooks, **Please note**: You must sign up by 5:00 PM the evening before the hike. **Time to Meet**: Please meet at 9:45 for introductions and sign in.

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.

Central Bank Digital Currency (CBDC) With Digital Currency they can: Have a complete government dossier on every detail of your life. Use your purchase history to maintain a detailed social credit score for every person. Provide tax breaks to corporations who hire people with admirable social credit scores. Only grant government contracts to corporations with employees with admirable social credit scores. Adjust health insurance premiums to incentivize people to develop admirable social credit scores. Connect your social credit score with a digital ID to encourage you to look at only approved web sites when surfing the internet. Viewing conspiracy web sites could lower your Social Credit Score and make it difficult to get a job. With their electronic chain around your neck, they can control where, when, how you travel, what food you are allowed to buy etc. They will love the power to only allow you to use your digital money only where they want you to shop and allow you to buy only what they prefer you to buy. Require you to have to have a license to use your money. They will call it a Digital Currency License. Require you to take any vaccine they want you to take to maintain your digital currency license. Tax you in ways we have not even imagined. Adjust your income tax rate based on your social credit score. Use AI to increase your income tax rate if you eat too many hamburgers because they will tell you eating too many hamburgers will increase global warming. This is just one example of many behaviors they might not approve of. Adjust individual prices for different individuals. They will be able to make you pay more per pound for hamburger if you purchased too much red meat during the past 30 days. Require you to buy so many pounds of soy burger for every pound of hamburger to save the planet and increase the profits for the soy burger manufacturers. Turn off the digital money of people they consider to be spreading misinformation. Turn off the digital money of people they consider to be dangerous conspiracy theorists. Turn off your money at 8 PM if they want a curfew at 8 PM Turn off your money in another state if they do not want you to drive to another state without permission. Turn off your money when buying guns or ammo if they do not want you to buy guns or ammo. Turn off your digital money more than three miles away from your home if they want you to stay within three miles of your home during the next epidemic. Etc. etc. etc. From the standpoint of the government, one beauty of digital money is that your money is one “state emergency” away from being the government’s money. All they have to do is to take your digital money out of your Central Bank Digital Account for the “good of all”. It is not as easy for them to do this with physical cash, gold, stocks, or silver etc. Anything they **can** do, they will do. The essence of slavery is control. Digital Currency will enable them to make you, their slave. (in a global digital concentration camp). .

Join the Bitcoin District Book Club! We meet every month to explore new and exciting rabbit holes by reading books that are popular with bitcoiners. Join us for a deep dive into Jeff Booth’s The Price of Tomorrow: Why Deflation Is the Key to an Abundant Future. In this eye-opening session, we'll explore the collision between exponential technological growth and our aging economic systems. Booth argues that while technology is naturally deflationary—making things cheaper and more abundant—our current financial world is built on a requirement for inflation and ever-increasing debt. We’ll discuss how this "clash of worlds" creates social polarization and why embracing a new economic framework is the only way to ensure a peaceful, prosperous future. Whether you are interested in the mechanics of technology or the future of sound money, this book provides a vital roadmap for the era of Bitcoin. Buy the book on [Amazon](https://a.co/d/0iNJamvq) **Event Notes:** * Discussion Starters: We'll have a few key questions to kick us off regarding technology and debt, but feel free to come with your own insights. * Future Reads: Let us know if you have recommendations for future book club selections!
