[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Artemis II and Beyond,”** on how the recent space mission fits into long-term plans for the Moon, with Michael J. Neufeld, retired senior curator for the Space History Department of the Smithsonian’s National Air and Space Museum. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond](https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond) .] NASA’s recent, spectacular Artemis II mission is a sign that the United States is serious about sending humans to the Moon again. Gain an understanding of how Artemis II fits in both past and planned lunar missions with historian Michael Neufeld, who was lead curator of the Smithsonian’s Destination Moon exhibit. He has taught at Johns Hopkins, Colgate, and other universities, and is the author or editor of nine books dealing with the history of technology. He’ll start by looking at the aftermath of the Apollo program of a half century ago and why it ended only four years after its first lunar mission. He’ll consider why no lasting lunar programs emerged from major announcements by two presidents, George H.W. Bush and George W. Bush, that astronauts would be going back to the Moon and on to Mars. His vividly illustrated lecture will then explore how Artemis is a product of a human spaceflight program that has changed dramatically over the past 50 years. We’ll look at how collaboration with Europe, Canada and Japan became integral to the shuttle and International Space Station programs, and how the rise of new commercial space companies such as SpaceX has enabled NASA to buy both space services and space craft. Both international and commercial partners are involved in the latest Moon efforts, with SpaceX and Blue Origin expected to supply the landers to take astronauts down to a planned base on the Moon’s South Pole. How soon will any of this happen? Probably not as quickly as NASA says, but the specter of a Chinese landing on the Moon by 2030 is one obvious reason to keep things moving along. We’ll look at the sustainability of the Artemis space program for at least the next decade or so. You’ll emerge from the talk with no doubt that exciting days are ahead for space fans. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: The Artemis II mission launch (NASA photo).

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up **​​Description:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing. We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of. The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger. · 🤯 Learn more about the Cash-Flow Breakfast Club [HERE](https://cashflowbreakfastclub.com/) · 🥇 Get in the VIP List to be notified about the next event in your area [HERE](https://the.cashflowbreakfastclub.com/VIP) · 🤙🏼 Learn more about Launching your own Cash-Flow Breakfast Club Location [HERE](https://cashflowbreakfastclub.com/launch-your-own-club/) · 🤝🏼 Learn more about becoming an Affiliate-Sponsor at one of our club locations [HERE](https://cashflowbreakfastclub.com/affiliate-sponsors/) · 📷 View photos and videos of some of our recent events [HERE](https://cashflowbreakfastclub.com/about-the-cash-flow-breakfast-club/) · 😎 Looking to represent?

**\*\*You must purchase a ticket [here](https://sommcircle.clubexpress.com/content.aspx?page_id=4002&club_id=650343&item_id=2926832). \*\*** Ever find yourself nodding along at a wine tasting, wishing you knew what to actually say — or even what to look for? This is the evening that changes that. Speak Fluent Wine is a hands-on tasting experience designed to teach you the exact framework wine professionals use to evaluate what's in the glass. You'll go from "I just know what I like" to understanding \*why\* you like it — and having the words to say so. Here's what we'll cover: ?? Sight — What color and clarity reveal before the first sip ?? Nose — How to train your sense of smell and identify aromas with confidence ?? Palate — Decoding what your taste buds are picking up: sweetness, acidity, tannins, body, and finish ?? Structure — How the elements of a wine interact, including how acidity softens sweetness and tames tannins ??? Language — The vocabulary professionals use, demystified and made practical Once we've broken down the framework, Total Wine's expert staff will lead a short guided tasting — putting everything you've just learned directly into practice. Snacks and water will be provided. Cost is $25 No experience necessary. No judgement. Just great wine, a welcoming atmosphere, and the confidence you've been waiting to find. **\*\*You must purchase a ticket [here](https://sommcircle.clubexpress.com/content.aspx?page_id=4002&club_id=650343&item_id=2926832). \*\***

Tuesday, June 2nd, 5:00–8:30 PM Eastern Central Ohio Chapter Meeting IN PERSON IN COLUMBUS How I Get Private Lenders and Partners to Fund My Deals If you can’t fund it, you don’t have a deal. And right now, funding is where more investors are getting stuck. Private lenders are more cautious. Partners are asking better questions. And deals that look good on paper still fall apart when the money doesn’t show up. That’s why we’re bringing in a panel of investors who are actually getting their deals funded right now. You’ll hear how they’re finding money, structuring deals, and building relationships that lead to repeat funding. Here’s what you’ll learn: * Where they’re finding private lenders today * How they start conversations that lead to funding * What makes lenders and partners say YES * How they structure deals to be fundable * The biggest mistakes investors make when raising money * How to build repeat funding relationships **Early Session (6:00–7:00 PM Eastern):** **Having Trouble Finding Tenants?

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
