Libera Animae - Freeing the Soul
Main Library, Meeting Room 2B
Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen).
Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection.
All backgrounds are welcome.
How LLMs Like ChatGPT Actually Work and How to Build With Them
**First meetup of the Columbus AI Engineering group.**
We’ll kick things off with a practical, beginner-friendly discussion on:
**How LLMs like ChatGPT actually work — and how to build real applications with them.**
We’ll cover:
* what’s actually happening under the hood (at a high level)
* why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.)
* how people are building real systems with them today
* where things break in practice
This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A.
Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join.
No slides, no fluff — just real conversation about real systems.
We’ll hang out afterward and get to know each other.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Arthouse Friday: THE DRAMA at the Drexel Theatre!
Join us as we get together for an Arthouse Movie Friday event to see the A24 dark comedy /romance / psychological-thriller, THE DRAMA! The film stars Zendaya and Robert Pattinson as a happily engaged couple whose relationship is challenged when one discovers unsettling truths about the other. Here are details, a trailer and our plan for this event:
DESCRIPTION: The film follows a happily engaged couple whose relationship is put to the test when an unexpected turn sends their wedding week off the rails. The film comes from A24, is written/directed by Kristoffer Borgli stars Zendaya, Robert Pattinson, Mamoudou Athie, Alana Haim, Hailey Gates and Zoë Winters.
QUICK WORD OF WARNING: The film hasn’t screened for critics yet and most of the details are being kept tightly under wraps. But, early buzz (possibly promotional) says the film is a brilliant psychological thriller/romance but also provocative, twisty and some contains occasional uncomfortable viewing! I love the cast and trailer, so look forward to seeing for ourselves!
ZENDAYA-PATTINSON TRIFECTA CHALLENGE: Robert Pattinson and Zendaya will star in THREE movies together this year, including THE DRAMA, Christopher Nolan’s THE ODYSSEY this Summer and Denis Villeneuve’s DUNE: PART THREE at Christmas!
TRAILER: [https://www.youtube.com/watch?v=6zmKcUa4Xxk](https://www.youtube.com/watch?v=6zmKcUa4Xxk)
PLAN: We’ll plan for 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! Advance ticket purchase not required for this theater but early arrival is advised. Possibly post-movie get-together at the nearby Rusty Bucket! Complete details will be confirmed/announced as the date gets closer.
Take care and look forward to seeing you there, Dan
Discount Tuesday: THEY WILL KILL YOU at the Gateway Film Center!
Join us as we get together for a Discount Tuesday / Choose Your Movie event to see your choice of two great films! Option 1 is the dark comedy/drama based on a true story TOW! The film stars Rose Byrne as a homeless Seattle woman how battles a towing company. Option 2 is the off-the-rails, over-the-top, action-comedy-horror THEY WILL KILL YOU! The film stars Zazie Beetz as a woman who answers a help wanted ad to be a housekeeper in a mysterious New York City high-rise not knowing its mysterious past! Here are details, trailers and our plan for this event:
TOW: This dark comedy/drama is based on a true story and follows a homeless Seattle woman who fights her way out of "tow-company hell" to reclaim the car that had held her life together after receiving a tow bill for $21,634. The film stars Rose Byrne, Ariana DeBose, Demi Lovato, Octavia Spencer, Dominic Sessa, Elsie Fisher and Simon Rex! The film premiered to solid reviews at last year’s Tribeca Film Festival where critics declared, “TOW is a winner!” It’s “a story of perseverance, heart, and real fight, the kind of small human story we see less frequently these days, but need now more than ever.” TRAILER: https://www.youtube.com/watch?v=qdkpcsuPAhA
THEY WILL KILL YOU: A woman takes a job as a housekeeper in a NYC high-rise, unaware of the building's history of disappearances. She soon realizes the community is shrouded in mystery. The film is directed by Kirill Sokolov and Zadie Beetz, Myha'la, Paterson Joseph, Tom Felton, Heather Graham, and Patricia Arquette. The film is being released immediately following its premiere at this year’s SXSW Festival earlier this month. Early reviews say it’s “an adrenaline rush of action-packed fights, tons of blood and gore and plenty of laugh-out-loud moments” and a movie that’s “unafraid to march to its own campy, violent, and clever little drummer!” TRAILER: https://www.youtube.com/watch?v=XYqQPiXpi4w
PLAN: Not exactly a “Choose Your Movie” event, more like an early show and a late one (or both if you’re feeling sparky)!
\* If you’d like to see TOW, please purchase your ticket for the 5:00pm showing and meet in the upstairs lobby between 4:40 and 4:50pm!
\* If you plan to see THEY WILL KILL YOU, please purchase your ticket for the 7:45pm showing and meet in the upstairs lobby between 7:25 and 7:35pm!
\* Tickets for both films on sale now and advance purchase is advised! Tickets just $5.00 ($6.50 after online fees when purchased via the GFC website). Once you have yours, please list your movie of choice and seat number in the Comments section of this event.
\* Also, as a reminder, close, convenient parking available in the nearby garage (Between 9th and 11th, just off High) and just $2 when you have your ticket validated at the theater!
Look forward to seeing you there, Dan

Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Going forward our meetings will be hybrid. You can meet us in-person or attend online
