Building Drones

Meet in the parking lot of the Handy Bikes Service Center. At the start of each ride, we'll go over introductions to have a sense of participants' cycling experience. Over the course of our rides, we'll address the following: group riding dynamics; safety (ABC check & trail hazards); gear shifting; hill climbing; audible and hand communication within the group, with other trail users, and automobile drivers; what to bring on each ride; etc... Bring your questions, water & a snack. When it starts getting dark earlier, we'll need lights as well. Helmets a MUST. If you can, and especially if you've had issues with your bike, come a bit early to have it looked at ahead of the ride. PS - all levels are welcome to join, however, be mindful that if you are an experienced rider, please be prepared to ride at the pace of the newest rider in the group. Each week, depending on who's in attendance, and participants' riding ability/comfort level, we may do skills practice as a group in the parking lot or at the west end of Wheeler Ave. Once everyone is comfortable, we'll go for a ride on local trails and neighborhood streets and finish back at the shop. Happy Pedaling !! \~Maya

**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: * What is the exact definition of the Subconscious Mind? * How does it inflict unwanted feelings and anxiety in you? * What determines how much pressure it exerts on a person? * What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center.

The idea of achieving “World Peace” is thought by some to be a utopian fantasy – a dream – something that sounds nice but is too far out of reach. But is it really? What if peace is not just possible but actually inevitable? Humanity’s history is riddled with war and conflict. There isn’t a community in this world that hasn’t in some way been touched by war and their effects, with so many still suffering today. Though we have made great strides as a global society, we still seem to be surrounded by aggression and hate, by injustice and inequity. Conflict seems to rule society in our media, economic, political, and religious systems. Many even believe that conflict is intrinsic to human nature. But is it actually? Or do we have a higher calling as our true, spiritual nature? Might recognizing and nurturing this nature help us move beyond this cycle of destruction? Destruction is easy, but peace is difficult. It must be built and it must be maintained. At times this task can seem daunting to say the least. But it’s not out of reach. All around us we can find glimmers of hope and the promise of a better world. But how can we actually achieve it? Is it a process out of our hands? Or do we have agency in bringing it about – and in determining how quickly? Is there a role that each of us can play in achieving the promise of world peace? Are there spiritual qualities and virtues we can develop to bring about the changes necessary to achieve this? How might we support one another as we work together to build a more secure, more peaceful world? Come join a different kind of conversation – one that welcomes every perspective in a search for the underlying truths that unite us all – on what will be required to achieve true and lasting peace. Join us for an open and respectful conversation where participants can share perspectives, experiences, and insights. Whether you come to speak or simply to listen, all thoughtful voices are welcome.

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.

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 is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.

If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
