No Fooling. Agricultural Research Center Toastmasters is holding a meeting on April 1, 2026 at 5:00-6:30 pm. Come join us as we get a little silly. \-\-\-\-\-\-\-\-\-\- ARE YOU READY FOR A LIFE-CHANGING, CAREER-ENHANCING EXPERIENCE? The Agricultural Research Center Toastmasters in Beltsville, Maryland meets on the first and third Wednesday of each month to practice our communication and leadership skills. We follow the educational program of Toastmasters International. We have great success individually and as a group. Our members are from different cultures and backgrounds. Several of us are scientists for the US Department of Agriculture. Others work at the Patuxent Wildlife Research Center. Our members also are tax preparers, translators, and teachers. Each year in the spring we hold a beginners class. The next class will be in March 2026. Visit our webpage at http://arc.toastmastersclubs.org/ .

At this event you'll discover how to better understand and control your subconscious mind, helping you overcome doubts and fears. If you have anger issues, depressions and anxieties. this event will show you how to overcome them.

We are a President's Distinguished Club and welcome new guests! Meeting is every Wednesday.

Wednesday night skate and chill is our weekly group ride. DCESK8 has been hosting this weekly ride for several years now. We are very active in our group chat and that is where you will find the most up to date information on the rides. Follow the link below to join. Join our Telegram chat here https://t.me/dcesk8 to stay current on what's going on in DCESK8. Our ride meets up at the Lincoln Memorial, near the southwest side of the Reflecting Pool and the Korean War Memorial. That is on the left side if you are looking at the Lincoln Memorial. We meetup at 6:30pm, with the ride leaving at 7:00pm.

It's the first Thursday of the month, and that means we will be replaying a game we played recently - Manhattan Project: Energy Empire. We have two copies of the game. So we can accommodate 10 players. RSVPs will be set at 10. Anyone joining after the 10 spots are full will be put on the waiting list. If you have a copy of MM:EE, then let us know, and we will increase the RSVPs. Manhattan Project: Energy Empire Description: From the ashes of war, nations rise to power in the atomic age! In ***Manhattan Project: Energy Empire***, each player takes control of a nation struggling for power in the latter part of the 20th century. They build up their nation’s industry, commerce, and government by acquiring resources, building structures, and tapping sources of energy. The major threat in *Energy Empire* is not war, but uncertain global impacts, that result from side effects of industrialization and pollution. Many actions come with a cost. So, as nations become more industrious, they also increase the amount of pollution in the environment. Careful use of science can mitigate the harmful effects of industry, and can also help avert global crises. *Energy Empire* uses worker placement, tableau-building, and resource management mechanics. On each turn, a player can choose to either work or generate. On a work turn, a player plays a single worker on the main board, then uses workers and energy to activate cards in their tableau. Players may spend energy to use an occupied space on the main board, so no spaces are ever completely blocked. On a generate turn, players get to renew their supply of energy by rolling "energy dice" that represent nuclear, coal, oil, solar, and other forms of energy.

***Meet us in the Rockville Library, Collaboration room #4 where we will attempt to run clean scans of gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) Meet us in the Rockville Library, Collaboration room #4

The nearby Abner Cloud House is the oldest building on the canal, dating back to 1802. After 145 years of business, the fourth generation of the Fletcher family retired in 2004, and Guest Services Incorporated, a National Park Service concessionaire, assumed responsibility for the operation of the concessions. The area surrounding the boathouse was then officially named Fletcher's Cove, though most people still call it Fletcher's Boat House. About the C&O Canal: The Chesapeake and Ohio Canal operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains. The canal’s roots begin with George Washington’s dream of a waterway trade route. 74 locks were built. About the Labyrinth: One of the most interesting features in the park is the labyrinth, located towards the western end of the park. Labyrinths, which date back to ancient times, encourage contemplation on the journey from the outer edge along a circular path to the center. The TKF Foundation, a non-profit organization that promotes urban green spaces to facilitate community healing, provided funds for constructing the labyrinth and for a teak bench and a diary for visitors to use to record their experiences there.

Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **WiFi HaLow: Introduction and Practical Use** with **Alex Barbur**. Details are are [core.radio](https://core.radio).

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
