I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

**MoCo Psychedelic Society — Monthly Gathering** 📅 Date/Time Sunday April 19th \| 1:00 – 3:00 PM 📍 Charles E\. McGee Public Library\, Downtown Silver Spring — Small Room *** Come join us for our monthly gathering — a space for fellowship, learning, advocacy, and community connection. Whether you're a familiar face or joining us for the first time, you are welcome here. *** **✨ This Month: Psychedelic Primer, Part 1 of 2** Are you new to psychedelics, or simply curious to learn more? This is the meeting for you. We're kicking off a two-part educational series with a friendly, accessible overview of psychedelic medicines — what they are, how they work, and why so many people and researchers are paying close attention to them right now. We'll take an in-depth look at five substances: * 🍄 **Psilocybin Mushrooms** * 💊 **MDMA** * 💉 **Ketamine** * 🌿 **Ayahuasca** * 🔬 **LSD** No prior knowledge is required — just curiosity and an open mind. *** **A Few Important Notes** The MoCo Psychedelic Society is a community space for education, connection, and advocacy — not a venue for sourcing or sales. All information shared at this event is for **educational purposes only** and does not constitute medical advice or encourage the use of any illegal substance. A note on legality: Most psychedelic substances are currently classified as **Schedule I** controlled substances by the DEA. Their use outside of clinical trial settings or states where they are becoming legal remains illegal in the United States. **Ketamine** is an exception — it is legal when administered by a licensed medical professional. *** We hope to see you there. Come as you are. 🌱

It's April and it's time to get outside! We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, April 19 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
