**Tired of surface-level conversations?** Join us for *Ditch the Small Talk*—an evening of deep, real connection with strangers who are down to go there. We’ll meet at the church (we are a secular group), break into small groups, and draw questions from a deck of cards designed to spark vulnerable, honest conversations. ***Rules:*** 1. Don't debate politics. 2. Keep what is shared in the group within the group. 3. If you need to use your phone, step away from your group first. \*\*If you show up late, please hop into a group and don't interrupt the speaker. Just sit down in a group of your choice, and they'll bring you up to speed when whoever is talking finishes. Community of Christ church: 3526 Massachusetts Ave.

For safety due to the width of the trails and darkness we will be limiting to 15 Members. The full moon in April 2025, also known as the "Pink Moon" or "Paschal Moon", 
The full moon always lies opposite the sun in the sky. Consequently, it is visible all night. All full moons rise along the eastern horizon close to the time of sunset. Likewise, all full moons set along the western horizon close to the time of sunrise. At full moon, the sun, Earth, and the moon align in space, with Earth in the middle. And, the moon’s day side – its fully lighted hemisphere – directly faces us. That is why the moon appears full.
 We schedule the moonwalk when the moon can be seen in the Early evening. So you can be home and be tucked into bed. Hike distance is 2-21/2 miles and 1-1/2 - 2 hours with time for a bite to eat afterwards. We can make arrangements for a light dinner and drinks after the hike at local restaurant. Flashlight or lighting is required. Wear appropriate hiking gear and clothing. Live when you’re alive To make a difference you have to be different

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.
