# FAQs
**Do all ideas have a chance at getting funded?**
Not all ideas will move forward after initial pitches on Saturday. Once pitches are complete, we’ll vote for top ideas and form teams around the 4 – 7 ideas with the most votes. You must recruit **at least four total team members** (including the founder) to move forward and have a chance at getting funded on Sunday. If your idea doesn’t move forward, you can join another team!
**Do I have to submit my idea online prior to the event?**
Unlike previous years, we don’t have the option to submit your idea online prior to the event. Instead, everyone will be going through a brainstorming exercise on Saturday that’ll help you prepare for your initial pitch.
**Will we be working for 24 hours straight?**
Nope. The event is split over two days. You’ll be building on Saturday and pitching on Sunday.
**Do I have to pitch an idea?**
Nope. You can also simply join a team.
**What types of entrepreneurs does GBH support?**
While GBH most often works with technology startups, we support *any* organization (for- or non-profit) that makes an impact on health in the US or across the world.

Pranic Healing Level I - PH I--- DAY 2 of 2
MCKS PRANIC HEALING® Level I
In PRANIC HEALING® Level 1, you learn the basics of working with your energy aura, including learning to "scan," or feel the energy, to "sweep," or clean away congested energy, and to "energize," or supplement areas in your aura that have a pranic deficiency.
PRANIC HEALING® has been taught to doctors, nurses, massage
therapists, acupuncturists, chiropractors, shiatsu practitioners, and many others in the healing field. It has allowed them to heal confidently and consistently in the shortest learning time possible. These professionals find PRANIC HEALING® very effective and easy to apply.
Other topics covered in PRANIC HEALING® Level 1:
Energetic anatomy: You will learn to work with the network of chakras, meridians and auras to accelerate the healing processes of your body.
Preventive healing: You will learn to remove the negative energetic patterns of a disease to prevent it from fully manifesting as a physical ailment.
Self-Pranic healing: You will learn to apply these healing techniques to accelerate your own healing.
Step-by-step techniques for ailments related to your:
respiratory system, e.g., asthma,; circulatory system, e.g., heart ailments; gastrointestinal system, e.g., irritable bowel syndrome; musculoskeletal system, e.g., arthritis and back pain; reproductive system, e.g., menstrual problems. You'll also learn how to address common problems as migraines and sinusitis.
Additionally, you'll learn to apply distant healing to loved ones who are not present in the room with you.
All PRANIC HEALING® courses are "experiential," which means that you learn by actually performing the techniques and exercises in class - on yourself and those around you. During class, all the principles will be explained thoroughly and you will practice the techniques exhaustively so you will be confident in your ability to produce positive results when you finish the course.
This is Day 2 of 2 Attendance at day one is required to attend day 2.
The Course text book is Choa Kok Sui, "Miracles through Pranic Healing" Please bring this with you to class.
PRANIC HEALING® Level 1 is a prerequisite to all other GMCKS courses.

Nature Loving Fest | Spring Edition
Join us for the Spring edition of [Nature Loving Fest](https://www.facebook.com/events/895148649812928), a small, thoughtfully curated outdoor gathering celebrating vegan eats, handmade goods, and the beauty of the season.
Formerly known as our Vegan Pop-Up, this new chapter reflects what the event has always been — a space rooted in nature, community, and intentional living. Expect around 20 local vendors offering seasonal vegan eats, small-batch bakes, handcrafted goods, and earth-conscious products.
Come support local makers, share good food, and celebrate the beginning of a new season with us.
Admission is Free.
Walk & Talk About Life's Big Questions
[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations.
If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!).
**HOW IT WORKS**
**Step 1: Bring a topic**
Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event.
**Step 2: Circle up & share**
We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds.
**Step 3: Walk, talk & float**
We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!"
**Step 4: Feel more alive**
Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times.
*For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)*
**HOW TO BRING A GREAT TOPIC**
A great topic = something you're genuinely curious about.
Recent topics include:
* "What are you passionate about right now?"
* "What makes a good friend?"
* "What's a belief you used to hold that you've completely changed?"
* "How do you want to be remembered?"
* "What would you do if money wasn't a factor?"
Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter.
**WHAT TO EXPECT**
This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.*
But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here.
**FAQ**
* Wear casual athletic attire and sneakers. It's a long walk!
* We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space.
* We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space.
* Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know.
* Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic!
**LOGISTICS**
* If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event.
* This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs.
* Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details.
* If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋
**IF YOU WANT TO GO DEEPER...**
[The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up.
* This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

Using Philosophy to Cope with Current Events
So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

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.
CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again.
We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all.
Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

HTML5 Master Series (Class 01 of 04) (SPECIAL OFFERING)
**PLEASE READ THE FOLLOWING IMPORTANT NOTES:**
1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring.
2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis.
3. Each class, from BOTH a sign-up and fee perspective, is a separate entity.
**Introduction:**
HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today.
One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences.
A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites.
Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires.
**The breakdown of the four-class series is as follows:**
**Class 1: Introduction to Web Structure and Basic HTML5**
This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document.
* **Topics**:
* **Web Architecture Overview**: How browsers, servers, and web pages interact.
* **HTML Fundamentals**: Understanding elements, tags, and attributes.
* **Basic Document Structure**: Using !DOCTYPE html, html, head, and body.
* **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br).
* **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a).
* **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website.
**Class 2: Semantic HTML5 and Multimedia Integration**
Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia.
* **Topics**:
* **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article.
* **Images**: Adding images using the img tag and attributes like src, alt, width, and height.
* **Multimedia**: Embedding audio and video content using the audio and video tags.
* **File and Folder Structure**: Best practices for organizing project files and managing file paths.
* **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file.
**Class 3: Forms and User Input**
This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input.
* **Topics**:
* **Form Basics**: Using the form element, action and method attributes.
* **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit).
* **Form Elements**: Utilizing label, textarea, select, option, and button.
* **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern.
* **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation.
**Class 4: Introduction to CSS3 and Basic Styling**
The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible.
* **Topics**:
* **CSS Fundamentals**: The role of CSS, selectors, properties, and values.
* **Integrating CSS**: Using inline, internal, and external style sheets.
* **The Box Model**: Understanding margin, padding, border, and content for basic layout.
* **Basic Styling**: Changing colors, fonts, and text alignment.
* **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels.
* **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.
