3. What you can help others with
Round 2:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
Round 3:
* Community events you wanna plug. If none, that's cool too.
**After the introduction circle, everything is self-organized!**
1. For the rest of the day, folks work on their projects, providing one another with help, and/or socialize. It's fully up to you.
**Location**
We will be at Gateway Office Building, a few blocks north of the library in The Square at Rockville.

* **Verbal Consent:** Please be sure to ask and wait for a yes before hugging or initiating any physical contact, and encourage each other to speak openly about consent and personal boundaries. This helps foster a culture where personal boundaries are supported and attendees are empowered to speak confidently of their limits. (i.e. “Can I give you a hug?” “No thank you, but I would love a handshake.”)

A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Here’s the gist:
We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat.
Most importantly, we’re excited to meet you!
Catch you on Saturday,
Diego / Ian / Cayden / Nate / Otasha / Lia / An

Socrates Café Rockville Meetup
Socrates Café are gatherings around the world where people from different backgrounds get together and exchange philosophical perspectives based on their experiences, using the Socratic Method of inquiry (asking and answering questions). Today, there are hundreds of such gatherings, coordinated by volunteers, worldwide.
Though this may be considered a "philosophy" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things.
Please post any questions you would like the group to consider on the meetup event's page; in the comments section. Several days before the meetup I will post a link to a voting form in the comments section, and everyone can vote on their preferred questions. The questions with the highest and second highest number of votes will be discussed.
Hope to see you there!

Why Classical Physics Could Not Unify Gravity: The Missing Density Constant
Date : Dec 20 2025 13:00 - 15:00 EST
Title: Why Classical Physics Could Not Unify Gravity: The Missing Density Constant
Summary: Classical physics divides nature into two regimes: a quantum world governed by the Planck constant h, and a gravitational world governed by the Newtonian constant G. Despite one century of effort, the two regimes remain formally incompatible because neither framework contains a parameter that characterizes the density of space itself. In this paper, I argue that a fundamental density scale—denoted \mu_g—is logically necessary for any unified physical theory. Building on recent geometric models where space evolves as a helical motion, I show that the familiar constants G, \hbar, and c correspond to radial, torsional, and axial components of the same geometric motion. From this perspective, h cannot serve as the universal constant of unification because it measures action, not density. The density constant \mu_g provides the missing bridge: it allows gravitational coupling to be expressed as a property of space itself and reveals that the quantum constant \hbar is also a geometric quantity, proportional to \mu_g c \ell_\Omega^2. This analysis explains why classical and quantum physics have remained disjoint: both lack the necessary density scale. I conclude by proposing that \mu_g is not an additional assumption but a fundamental property of space that any geometric unified field theory must incorporate.
References to the prior geometric theory by Zhang Xiangqian and Xu Yuchuan are included to situate this work within the emerging framework of helical-space physics.
Speaker: Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.
Note: This is an online event. The Zoom registration form will be provided no later than one hour prior to the event start time.
ASL Brunch on Sundays in Greenbelt
Join our ASL Brunch on Sundays in Greenbelt! All ASL users and learners are welcome.
Brunches are alternately held at two restaurants in Greenbelt, both in the same town plaza.
ODD WEEKS: 1st, 3rd, and 5th Sundays, we meet at Cedars of Lebanon, 103 Centerway.
EVEN WEEKS: 2nd and 4th Sundays, we meet at New Deal Café,113 Centerway.
We are the Greenbelt ASL Community, a group of both Deaf and hearing people who hang out, chat about everyday goings on, trade stories, get to know each other better, and of course, enjoy food together. Many members use ASL as their primary language, several are interpreters or other fluent ASL users, while others are ASL learners who wish to improve their skills while making new friends.
Before or after brunch, you can visit the farmer's market and small coop grocery store in the plaza.
Please RSVP so we can contact you via email if needed.
Our group is on Facebook as Greenbelt ASL Community. Some longtime Brunch attendees don't mark their attendance here, so feel free to stop by even if you don't see others who have RSVP'd on Meet-up.
