Title: An Easy Intro to Feynman's Quantum ElectroDynamics (QED) Summary: One of the most delightful and informative physics books ever written is Richard Feynman’s QED. In this short book, Feynman undertook the daunting task of explaining his Nobel-Prize-winning theory, Quantum ElectroDynamics, without any math except in a few elaborating footnotes. Remarkably, he succeeds! In this talk, Terry replicates many of his arguments to show how you, too, can understand one of the most fundamental mechanisms of physical reality by using not much more than lots of tiny one-hand clock dials moving through space. Speaker: Terry Bollinger is a computer scientist Speaker: Terry Bollinger is a computer scientist with BS, MS and Professional degrees from the Missouri University of Science and Technology.

This is a **Saturday hangout for young entrepreneurs and builders** who want to meet like-minded people and actually make friends. We’ll meet at the **Lincoln Memorial**, on the **west side near the Reflecting Pool**, and take a walk around the area till the sun sets. Afterward, anyone who wants to keep hanging out can grab **coffee/tea or a small bite nearby (Maman)**. This isn’t a networking event or a pitch session. It’s for people who are interested in building things (or thinking about it) and want a solid group of people around them outside of work. You don’t need a startup, a title, or a plan - just be open to meeting people you’d actually want to hang out with again. Most people will be coming solo so don't be shy :)

meet at Tysons Corner Mall Upper Level Food Court

**🎉 Book Swap: Bring Your Books to the West End Neighborhood Library! 📚** 📅 **Date:** Saturday, February 21st, 2026 🕒 **Time:** 3:00 PM - 5:00 PM 📍 **Location:** West End Neighborhood Library - 2301 L St NW, Washington, DC 20037 **Agenda:** * **3:00 PM - 3:30 PM** \- Check\-in and chat * **3:30 PM - 4:00 PM** \- Introductions * **4:00 PM - 5:00 PM** \- Book swap **Please note**: * Gently used books are ideal for swapping. * If a book you bring isn’t swapped, you are responsible for taking it home. * This is a “stay-and-swap” event, so please join with the intention of engaging and connecting with the group.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.
