**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.

She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

[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).

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.
