Bring a friend, bring family, and bring that neighbor that you kinda know... Come one, come all for some free table tennis. Note: Because we have been playing regularly for years, members tend not to RSVP. If there are any questions, feel free to message.

**This talk has completely sold out in advance and no door tickets will be available.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Ballistic Missile Defense Question,”** on the operation of a controversial defense system and the debate over its use, with Dean Wilkening, a physicist and defense system researcher formerly at the Johns Hopkins Applied Physics Laboratory, the Lawrence Livermore National Laboratory, Stanford University’s Center for International Security, and the RAND Corporation. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-ballistic-missile](https://www.ticketleap.events/tickets/profsandpints/dc-ballistic-missile) .] Ballistic missile defense has been a contentious political issue in the United States, especially after President Ronald Reagan’s 1983 speech calling for a “Star Wars” style barrier to Soviet nuclear weapons. Ballistic missile defense is also among the most expensive items in the Pentagon budget for research, development, test and evaluation, with funding estimated at $10.6 billion in 2026. Most recently, ballistic missiles have been making headlines as a result of Iran’s recent ballistic missile attack against Israel, Russia’s ballistic missile attacks against Ukraine, and President Trump’s call for America to be defended by a “Golden Dome” similar to Israel’s Iron Dome system. But is relying on ballistic missile defense (BMD) systems practical and wise? Hear that question tackled by Dean Wilkening, who recently retired from the Johns Hopkins Applied Physics Laboratory, has spent much of his life studying a range of defense matters such as hypersonic weapons and ballistic missile defense, and who has published extensively and advised national boards and government agencies on his findings. Dr. Wilkening will discuss the technology underlying BMD systems, which seek to use precision guided munitions to essentially “hit a bullet with a bullet” to thwart attacks. You’ll learn about the support systems, including sensors and command and control systems, critical to making it all work. Then he’ll give an overview of the debate over ballistic missile defense systems, typically split along partisan lines. We’ll look at the evolving missile threat, which includes both conventional and nuclear ballistic missiles as well as hypersonic weapons, and the potential for armed conflict with Russia, China, North Korea and Iran. Dr. Wilkening will look at whether BMD systems meet the test of working technically, being able to survive attack, and being cost-effective at the margins. Finally, he’ll take on the big-picture question of whether ballistic missile defense is inherently “destabilizing.” Do they stimulate arms races? Do they actually make nuclear war more likely?

I have couple extra tickets for this game. Meet me at the Haagan Diaz Ice Cream Store at **703 7th St NW, Washington, DC 20001 at 645PM and we will enter totgether.**

The city of Laurel has reopened the community centers! GCOM Laurel will be happening again Thursday night! We’ll be gaming from 6-9pm. Masks are still required and if you’re not feeling well, get better and join us next week. We’re at the Robert J DiPietro center!

***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! We want to continue with full systems testing, after the powerline component repair - and overall just 'get back into it'. Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

Yummy Bowl serves Mongolian BBQ, sushi, and ramen. Mongolian BBQ is a stir-fry style of cuisine where you place a selection of raw noodles/rice, vegetables, fruit, and protein in to a bowl along with your choice of sauces and the dish is cooked for you on a large, round grill while you wait. Every bowl is delicious and you are the chef so the selection gets better every time! Expect entrees in the range of $17 plus tax and beverage. This is a great opportunity to meet others who are new as well as those who have been around a while! Look for GRASP table flyers and Eli's GRASP shirt to easily find the group. We can't wait to see you there!

We will be playing **Heat: Pedal to the Metal** with up to 8 players. All experience levels welcome. Expect the game teach to start promptly within the first 10 minutes. **Heat: Pedal to the Metal** puts players in the driver's seat of intense car races, jockeying for position to cross the finish line first, while managing their car's speed if they don't want to overheat. Selecting the right upgrades for their car will help them hug the curves and keep their engine cool enough to maintain top speeds. Ultimately, their driving skills will be the key to victory! Find [here](https://www.youtube.com/watch?v=Ychy0Tgegjk&pp=ygUjaG93IHRvIHBsYXkgaGVhdCBwZWRhbCB0byB0aGUgbWV0YWw%3D) a how to play video on youtube.
