Economics

What Happened to the Energy Transition? To land a ship on a moving target, the moon, for example, from a moving object, the earth, requires an enormous attention to facts and a mastery of detail. Getting any of these wrong can lead to disaster. Climate science tells us we must transition to a zero carbon society—and fast. But are climate-deniers the only obstacle to that transition? We will discuss the work of economic historian Jean-Baptise Fressoz who suggests that even as we move to solar panels and electric vehicles, rather than “transitioning” to a zero carbon world we will continue to consume more, and more, and more and produce more carbon dioxide. Is there a way out of here? As harrowing as it sounds, its best to pay attention to the facts and master the details so we can discuss real solutions. Perhaps, a solution that depends on a transition in our ethical thinking. In-person and available on Zoom When: Sunday, April 12, 2026 Coffee available at 10:45 AM, Speaker begins at 11:00 AM Where: Green Hedges School 415 Windover Ave NW, Vienna, VA It's more fun in person (and the coffee is free), but you can participate by Zoom at [https://us02web.zoom.us/j/83422695892](https://us02web.zoom.us/j/83422695892) Jim Ball and his family are longtime members of Ethical Culture.

(NOTE: If you feel sick/unwell, stay home, no worries. We'll be around next month. ALSO: This is a new location due to renovations at the Hyatt) WHO: DC-Area Global Nomads/TCKs WHEN: 7pm First Friday of Every Month WHERE: Spotted Zebra at Marriott Metro Center, 775 12th Street NW, Washington, DC 20001 WHY: If you grew up abroad as a kid, come on over and meet other folks (ranging in ages of early-20s to late-60s) who know the true meaning of "So where are you from?" If you can't make it this month, no worries, they're generally on the first Friday of every month, with a few exceptions, particularly if it's a holiday weekend (Independence Day, Columbus Day, etc) or if I'm out of town. *Ideas for other possible locations always welcome (preferably ones that are relatively quiet -- good for conversation -- and serve wine/beer/booze).*

**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?** **Attend and find out.** This group is sponsored by the Dianetics Life Improvement Center

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!

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.

Let's play monopoly in the open area called "The Landing" at the Crystal City Shops. The Landing is right at the Crystal City metro stop and, if you're driving, there is free parking [on weekdays after 4pm and weekends] in the garage. See below for more details. With many tables for games and nearby eateries in the mall, it is a fantastic location for playing board games. We'll be starting at 3:00 pm, but feel free to wander in whenever you'd like.Please RSVP to play. If you'd like to start earlier, feel free to mention that in the comment section. If everyone is already in the middle of games when you arrive, please don't hesitate to pull up a chair and watch a game in progress. We will play a minimum of 3 and a maximum of 6 people at each table. This is a friendly group of competitive and non competitive players and our different backgrounds and different experiences of Monopoly make for interesting conversation during the games. If you're taking the metro, exit at Crystal City and you can walk to The Landing without having to go outside. When you come up the first set of escalators, turn right to enter the underground shops and then turn right at Rite Aide. Continue straight and The Landing will be the large open seating area on your right, next to San Antonio Bar & Grill and Subway. If you're driving, parking is free in the garage. Enter the garage for 1750 Crystal Drive on 18th Street and take a ticket. (You'll need this to exit, but there's no charge). Take the elevators up to Level S. The Landing is the large open seating area next to San Antonio Bar & Grill and Subway. If that parking garage is full, exit the garage and turn left on 18th and left again on Crystal Drive. A second parking garage is located on Crystal Drive between 18th Street and 15th Street. This is a link to a map of the Crystal City Shops: http://www.thecrystalcityshops.com/ The Landing is in the yellow section on the map near the San Antonio Bar & Grill and Subway.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
