A place that was quieter and possibly private. 2. “I wish they accepted Bitcoin.” We’ve finally found a solution to these requests with The Daily Growler. We’ll have access to their private room, and you’ll be able to pay your tab with Bitcoin. Join us for a fun and relaxed social event! Enjoy delicious food and drinks as we chat about the latest news in the Bitcoin world. Everyone is welcome, whether you're looking for guidance, have questions, or just want to meet like-minded people.

Hi ladies. We will be walking the 4 mile paved loop. Meet in the Maple Grove Picnic area.

Let's check out a Popular Astronomy and Science Based Film at COSI Science Center on their HUGE 360 Degree 4K Spherical Dome Screen Theater, in which is touring the nation and has already sold over 10,000 tickets! COSI is one of the leading Science Centers in America. Alan Watts was one of the Most Influential Amateur Astronomers of the 20th Century and held fascinating views of the Galaxy. Tickets are only $33 plus a small fee and taxes and can be purchased here: [Trust the Universe: Immersive Dome Show](https://www.sphericalpictures.com/tickets) PLEASE purchase tickets for the 8:15 PM Feature on Friday, February 13. There seem to be at least 10 tickets left, possibly more. We should be able to sit together in the same row or at least in the general section. This is an exciting chance to view actual footage of the Solar System on a Large 4k Resolution Screen plus added in Cosmological and Astronomical Related Philosophy! We will plan on meeting at about 7:50 PM by the Atomic Cafe on the first Floor of COSI, where the Movie Theater is located, in order to give us time before the show starts to purchase refreshments. Parking is available at the COSI Garage and in the area on side streets and adjacent garages. We can also walk somewhere in the area and get food afterwards, if anyone wants to do so. Thanks and hope to see you come out!

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! 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 Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

Friday Night French Conversation Hour Bonjour tout le monde! (English Below) Je vous propose une soirée, ce vendredi qui vient, à l'hôtel Junto à Columbus. 19hr. 13 Vendredi 2026. C'est très bien située avec de l'espace extérieur et intérieur, un feu, un café (cafe se ferme à 19h; arrivez tot si ca vous interesse), un resto, et un bar. Le parking est payé est juste en face au musée des sciences COSI. Il y'en a aussi dans les rues mais un peu plus loin. Vous n'êtes pas obligé d'acheter quelque chose, car l'ensemble de l'espace c'est vraiment un grand lobby et de l'hôtel, mais c'est cool. J'ai parlé avec le management et ils sont ravis de nous accueillir, mais il n'y a pas de place particulière réservé pour nous. Ce sera à partir de 19h jusqu'à ? Moi, je suis Brandon. J'aimerais que ce soit un évènement mensuel et si l'espace ne vous convient pas, on peut discuter d'autres options. Je vais porter une casquette bleue et blanche qui dit "Québec." Venez nombreux! A tres bientot \-\-\-\- Hello everyone! It’s been a long time since we’ve had a Friday night French meetup. I suggest that we meet at the Junto Hotel in Columbus this coming Friday, 13 February 2026 at 7PM. There’s a great spot with both outdoor and indoor areas, a café (which closes at 7 p.m., come a bit early if that interests you), a restaurant, and a bar. Parking is paid and is located right across from the science museum called COSI. There is additional free and paid street parking around at varying distances. It’s a bit expensive, but you don’t have to buy anything since the area is really just a large hotel lobby. It's nice though. I spoke with management, and they’re happy to welcome us, though there’s no specific space reserved just for us. It’ll start at 7 p.m. and go until whenever. I’d like this to become a monthly event, and if this space doesn’t suit us well, we can discuss other options. Speaking and understanding French well is ideal but there may be learners there as well. I’m Brandon. I’ll be wearing a blue and white cap that says “Québec.” Come find us.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
