HHH Spring Edition. Does disappearing into the wilderness with a group of strangers put you on edge? Then come to a casual happy hour and get to know us first. This is a great time to meet your fellow outdoor enthusiasts and get connected - without needing to gear up. This time, let's go to DC and check out The Crown & Crow (Logan Circle). 7pm. The Crown & Crow is a massive underground bar with a speakeasy feel. The only signage outside is a gold emblem of a crow with a crown on it's head. Once you see this, follow the stairs down to the bar. Please update your RSVP if your plans change so that we have an accurate headcount. Thanks!

**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.

***Please read all and make sure you agree before you sign up.*** **Court Type:** Outdoor Sand **Level:** adv beginners+/intermediate (BB/A) **Transportation:** Parking will be right by the sand courts, behind the courts, and there is garage parking close to the courts. Metro is the Blue and Yellow Lines. **What to bring:** at least 3 bottles of water and a ball if you have one. **MAX:** 10 players per net. (1 Net) **Restroom:** Restrooms are across the street in the restaurants. **Host's Philosophy on This Event:** The purpose of this meetup is to create a fun and supportive environment where we can improve our skills, enjoy competitive games, and connect socially. While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. This is a space where you won’t be judged for making mistakes, ***but we do expect you to listen to the organizer if they make suggestions or adjustments***. We also expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for total beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level. **Skill Level:** 1. **If you want to know your level, please see the link below:** [Smiley Social Volleyball Levels](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/edit) **YouTube:** The games may be recorded and uploaded to our channel here: Let the host know if you have issues with this ahead of the event. [https://www.youtube.com/@mp02626](https://www.youtube.com/@mp02626) **ATTENDANCE:** **Player Selection:** Regulars > League Members > Smiley Attendance Ratio\* > Skills (BB>B) > New Members The host takes attendance very seriously. Please remove yourself from the event (if you can't make it) as early as possible to allow others to join. You will be marked as a ***no-show*** if you don't show up to the event. One no-show means you will be removed from the group. See the rules below. **\*The organizers can see the number of times you have attended events vs the times you have dropped out. If your drop rate is more than 50%, you may not be accepted to the going list.** [Smiley Social Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/edit) **Q&A** * Bringing your **dog** is welcome and encouraged. * *Can I come if I don't know how to play?* No, you may not. The host teaches a beginner's volleyball class that you may attend on Saturdays. * *Can I be late or leave early?* The host expects you to be there **on time** and leave on time. If you need to arrive late or leave early, please let the host know in advance. * *Can I come even if I am not on the going list?* No, sorry * Why Max the players at 10 when you can do 6v6? This court is already for 2v2; getting 6 players on each side is overkill. * How can I become a regular if I don't ever get to attend? You can attend my other events on weekdays/weekends. Show me you have good skills and bring good vibes! **Smiley Social documents:** 1. [Group Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg) 2.

Buddhist art is rich with beauty, symbolism, and deep meaning. From the sacred symbolism of the Eight Auspicious Symbols to the vivid imagery of the Wheel of Life and the peaceful presence of Buddha images, these traditional works of art offer more than aesthetic inspiration—they reveal a practical path to greater clarity, peace, and compassion that we can internalize and practice in our daily life. In this series, we’ll explore the symbolic meaning behind Kadampa Buddhist sacred art and discover how we can use this symbolism to illuminate our modern lives. Each session offers accessible explanations, guided meditation, and time for question and answer. **April 2nd:** Understanding Sacred Art **April 9th:** Meditating on the The Eight Auspicious Symbols I **April 16th:** Meditating on the The Eight Auspicious Symbols II **April 23rd:** The Wheel of Life: A Map of the Mind I **April 30th:** The Wheel of Life: A Map of the Mind II **REGISTRATION** Standard: $12 \| Financial Hardship: $6 \| Free for [Members](https://meditation-dc.org/membership/) [Pre-Register Here](https://meditation-dc.org/thursday-evenings/) Each class is available by drop in.

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.
