**ANNOUNCEMENT: [Venue change] SQ Collective has generously offered to host the venue for this session for free. It is only appropriate that we allocate some capacity to them (via a Luma event). This is a chance for folks in the AI builder community to participate in our group’s philosophy practice, and for us to broaden our audience within that community. If you have already signed up via Meetup, there is no need to double-register through Luma, should the Luma event be made public.** “You insist that there is something that a machine can't do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that.” —John von Neumann, in a talk at the Institute for Advanced Study at Princeton, 1948 “Everything is computer!” – Donald J. Trump, sometime in 2025 What is computation? These days, it seems more provocative to stipulate what *isn’t* computation. For instance, to suggest that the brain can be functionally anything other than a kind of computer is suspect in the current technological zeitgeist. It seems self-evident that any system of information processing to achieve some output can be explicated in terms of computation. At the foundation of this conviction is the Church-Turing thesis, which both gave a logical definition to and circumscribed the bounds of computation in the form of the Universal Turing Machine, “a most general formulation of machine” (Alan Newell 1980). The idea that the Universal Turing Machine is an abstract design template that can encompass any kind of information-processing system has led some to extend the scope of the thesis to physics itself: “any finite physical system can be simulated by Universal Turing Machines” (David Deutsch 1985). What do we make of such ideas? Instead of fumbling in the accreted fog of the present, a quiet philosophical dialectic was already underway at the time Alan Turing demonstrated Universal Turing Machines in his seminal paper *On Computable Numbers* in 1936. Ludwig Wittgenstein was a contemporary of Turing’s, and made a number of keen observations in the years that followed\*. In particular, Wittgenstein anticipated readings of the Church-Turing thesis such as the above as resulting from an uncritical acceptance of some inferences within Turing’s demonstration. In this session, we will recount the Church-Turing thesis, its various interpretations, the Wittgensteinian response, and what it all means. Join us to discuss and re-examine the notion of computation, in the hopes of coming to a clearer understanding of it. The format of this session will be a presentation followed by an open-ended discussion. \*Compiled in Remarks on the Foundations of Mathematics. By L. Wittgenstein

Calling all who create for the Kingdom: video makers, podcasters, designers, editors, and storytellers. We are gathering this Sunday afternoon to meet one another face to face, share what we are building, and ask how our craft can serve the Gospel rather than ourselves. Whether you are seasoned or just beginning, you are welcome. Bring your questions, your works in progress, and your hunger to make the unseen visible. We will talk tools and technique, but more than that, we will ask what it means to create as those who bear the image of the Maker. Come and be encouraged. Come and labour alongside others who carry the same burden.

What if a tennis class became the easiest way to meet new people? **The Best Group** combines structured, level-based tennis group classes with an optional social matching experience. Here's how it works: 🎾 Join a tennis group class with players of a similar level 🤝 Having joined a class, you can choose to be matched with **three other people you've never met before** for dinner. The difference? **Everyone at the table will already have completed a tennis group class with The Best Group.** Instead of meeting complete strangers with nothing in common, everyone shares the same experience, making conversations feel far more natural from the very beginning. Think of it as a Timeleft-style social experience—but with a built-in shared connection before you ever sit down for dinner. **Join the waitlist for early access:** [https://thebestgroup.base44.app/](https://thebestgroup.base44.app/)

🏛️ **WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 📓 **HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start. * 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! 💛 **WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group!

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
