Critical Design

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/silver-spring-md/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

Socrates Café meets twice a month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

is is an In-Person Writing Event at Three This is an In-Person Writing Event at Kaldi's Social House in Clarendon! Please join us. This is not a critique session or discussion event. If you're interested in attending one of our regular meetings to discuss the art and craft of writing or to review another's work, please join us for a regular meeting on Wednesdays from 7p-9p.

The Basilica of the National Shrine of the Immaculate Conception is significant for several reasons. ### What Makes It Special Even If You're Not Religious * The scale of the building is awe-inspiring. * The artwork and craftsmanship rival those found in famous European churches. * The chapels tell the story of immigrant communities that helped shape the United States. * It offers a rare combination of history, architecture, art, culture, and quiet contemplation in the heart of Washington, DC. Many visitors describe it as one of the most underrated attractions in DC because it combines the grandeur of a major monument with a peaceful atmosphere that contrasts with the city's busy museums and government buildings. * **The largest Catholic church in North America** and among the ten largest churches in the world. * **Home to more than 80 chapels and sacred images**, representing the diverse cultural and ethnic communities that make up the Catholic Church in the United States. * **Known for its breathtaking mosaics**, containing millions of pieces of colored glass and stone that cover walls, ceilings, and domes. * **A unique blend of Byzantine and Romanesque architecture**, making it visually distinct from the Gothic cathedrals many visitors are familiar with. * **Visited by multiple Popes**, including Pope John Paul II, Pope Benedict XVI, and Pope Francis. * **A national shrine rather than a local parish church**, meaning it serves as a place of pilgrimage for Catholics from across the United States and around the world. * **Dedicated to Mary, the Mother of Jesus**, under the title "Immaculate Conception," who is the patroness of the United States. * **Features one of the world's largest mosaic domes**, creating a remarkable visual experience even for visitors with no religious background. ### Join us for a casual visit to the Basilica. **Cost:** Free **Time**: 12:15 pm **Who can attend:** Everyone is welcome, regardless of faith background. Please dress respectfully for a place of worship.H

Date: June 7 2026 Sunday 10:00 am - Noon EDT Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts. Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation [Quantum AI Foundation](https://www.qaif.org/ "https://www.qaif.org/") Dr. Sebastian Zajac, member of QPoland [QPoland - QWorld](https://qworld.net/qpoland/ "https://qworld.net/qpoland/")

As usual, non-assisted bikers are most welcome. **About Jones Point Lighthouse** The lighthouse is one of the last riverine lighthouses in the country and the only one still standing in the Chesapeake Bay area. It was first lit on May 3, 1856 by keeper George L. Deeton. Today it is the focal point of Jones Point Park and a clue to area's history as a busy commercial center and naval base. Whale oil lamps were originally used to power the beacon at Jones Point, but in 1858 the Lighthouse Board allowed an Alexandria gas company to extend lines to the station. The land included one of the original District of Columbia boundary stones, which was installed by George Washington and marked the southern point of the ten-mile-square district. The stone is still visible today in the seawall just south of the lighthouse, and to the north of the lighthouse a marker designating the boundary between Maryland-Virginia can be seen. **About Fort Foote** Fort Foote was constructed in 1863 atop Rozier's Bluff to strengthen the ring of fortifications that encircled Washington, D.C. Two of the Guns that protected Washington are still there along with the remains of the fort's earthworks. **About the Woodrow Wilson Memorial Bridge** Also known as the Woodrow Wilson Bridge or the Wilson Bridge, the bridge is a bascule bridge that spans the Potomac River between the city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland. The original bridge was one of only a handful of drawbridges in the U.S. Interstate Highway System. **About National Harbor** National Harbor is situated on the banks of the historic Potomac River, just minutes from the nation’s capital. Featuring 350 acres of waterfront resort space, National Harbor is a destination unlike any other. The harbor is home to 160 stores, 40 restaurants, the Capital Wheel, and the best sunsets in the area. **Free Ride With GPS for E-Bike Lovers** Membership of the Ride With GPS E-bike Lovers club is now free as www.ebikelovers.com is generating sufficient income from ads to cover the costs.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
