Mid-Week Service
Mid-Week Service
## **Mid-Week Service: Renew Your Spirit** Join us every **Wednesday evening at 6:15 PM** for our Mid-Week Service, a dedicated time to pause, pray, and recharge in the middle of a busy week. Held in an intimate and welcoming setting, this service is designed to help you reconnect with God and find peace through His Word. ### **What to Expect** * **Deep Biblical Teaching:** We move beyond the surface, engaging in verse-by-verse studies of Scripture—such as our current journey through the **Book of Acts**—to gain practical wisdom for daily life. * **Community Prayer:** We believe in the power of collective intercession. Each week, we lift up the needs of our families, our city, and the world. * **Heartfelt Worship:** A time of singing and reflection to center our hearts on the presence of the Holy Spirit. * **Authentic Fellowship:** Connect with a supportive community of believers who are walking the same path of faith. Whether you are looking for a deeper understanding of theology or simply a quiet place to sit at the feet of Jesus, our mid-week gathering offers the spiritual nourishment you need to finish your week with strength and purpose. *** > *"But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have."* — **1 Peter 3:15**

Quantum Computing for Business (Exploring Opportunities Available Today)
Quantum Computing for Business (Exploring Opportunities Available Today)
Title: Quantum Computing for Business (Exploring Opportunities Available Today) Date: June 27 2026 Saturday Noon - 14:00 EDT Summary: Big media reports that current quantum computers are not able to attack business problems at scale. In Ron's experience, this is only about 95% true. He has found that certain types of quantum computers, specifically quantum annealers, are very good at solving constraint based optimization problems at business scale. This presentation will answer the question “What is quantum computing?” by comparing quantum computers to classical computers and describing the various types of quantum qubits. Ron 'll introduce what quantum computers can be used for and what they shouldn't be used for. Next, Ron will look at a number of quantum computing use cases that are currently available to businesses today. Finally, Ron ’ll present conclusions with a brief discussion of future hardware. There will be time for Q & A. Speaker: Ron has been fortunate to have worked in a broad range of technical disciplines during his career. Areas in which he developed expertise and innovative results include, digital hardware design, silicon functional architecture (chips), computer language compiler development, and medical software. Ron has recently immersed himself in quantum computing technologies and has obtained more than a dozen certificates across the quantum spectrum. These technologies include various hardware platforms, numerous quantum programming frameworks and quantum sensors. As a co-founder and CQTO of B2Quantum, Inc, Ron has served as a quantum computing Subject Matter Expert (SME) for a large pharma company. As a SME, he performed quantum computing use case analysis, strategic planning, budget guidance and risk analysis. Outside of the technical arena, Ron is a licensed pilot, certified open water SCUBA diver, bicyclist, wood worker and a once in a while artist.

In-Person Event: The Answers to Depression & Anxiety
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.

AI Agents 101: How to Make ChatGPT Do Actual Work
AI Agents 101: How to Make ChatGPT Do Actual Work
Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. 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.
