**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.** * Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers. * Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking. * We look forward to seeing you on the 10th! **Our Program will feature these presentations:** **The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)** This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from. You should. Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely. The technology did not change. Only the purpose did. **GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)** This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers. Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside. This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm. **From GIS to AI: Lessons from MIT’s Applied Data Science & AI Program**- **Julia Brodsky (Navy Federal Credit Union).** A practical look at one GIS professional’s experience completing MIT’s Applied Data Science & AI Certificate program, including key takeaways, challenges, and thoughts on how AI may impact the geospatial industry. *->If you’d like to present or sponsor a future GeoDC Meetup, please complete this [form](https://forms.gle/QbAXPfrDnX12GGaS8).*

Title: An Easy Intro to Feynman's QED, Part 3: Electron-Photon Interactions Date: June 13 2026 Noon - 14:00 EDT Summary: In his second QED talk on May 16, Terry discussed how Nobel Laureate Richard Feynman kept Einstein’s idea of a photon as a particle, but replaced the photon’s singular path through space and time with an integral of all paths the photon could have taken. In this final talk, Terry adds Feynman’s critical concept of how photons interact with another incredibly common particle, the electron. He shows the resulting model, called QED, describes not only most everyday phenomena, but also issues such as why antimatter can be interpreted as ordinary matter traveling backward in time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and Professional Degrees from the Missouri University of Science and Technology.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Lafayette’s Long Fight for Liberty,”** a look at the life, struggles, and legacy of America’s favorite fighting Frenchman, with Richard Bell, professor of history at the University of Maryland and author of *The American Revolution and the Fate of the World.* [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-lafayette](https://events.ticketleap.com/tickets/profsandpints/nv-lafayette) .] When the Marquis de Lafayette returned to the United States in 1824, Americans greeted him with a frenzy of affection unmatched by anything the nation had ever shown a single individual. Crowds filled streets, towns held ceremonies in his honor, Congress showered him with gifts, and parents named children for the French aristocrat who had helped win the American Revolution. Explore the extraordinary life behind that adulation with historian Richard Bell, whose excellent past talks have earned him a big following among Profs and Pints fans. Professor Bell will take Lafayette far beyond his familiar role as George Washington’s young protégé and the hero of Yorktown. You’ll learn how Lafayette became one of the Atlantic world’s most persistent champions of liberty—fighting for constitutional government, religious freedom, prison reform, press freedom, antislavery, and independence movements from Greece to Poland. You’ll also hear how Lafayette’s ideals repeatedly put him in danger, making him a target of kings, radicals, imperial powers, and revolutionaries who regarded him as “the most dangerous man of all.” Professor Bell will show how Lafayette’s life was full of contradictions: a nobleman who challenged aristocratic privilege, a centrist caught between monarchy and mob rule, an antislavery advocate whose efforts fell short, and a dreamer whose causes often failed in his lifetime. Yet Lafayette never stopped trying to make liberty universal. Come learn why Lafayette’s name still graces hundreds of American towns, parks, counties, schools, rivers, and lakes—and why his most important monument might be not any statue or place name, but the freedoms he helped generations of people imagine, demand, and defend. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation.
