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.

Join us for an eye-opening lecture where the speaker will break down complex ideas in a clear and practical way.
You’ll gain insights into:

✅ Its real purpose and function
✅ What determines the pressure it exerts on you
And the most important topic:
**How do you take control of your subconscious!**
But this isn’t just another lecture where you sit and listen passively. It’s interactive and engaging—you can ask questions at any time.
📅 Reserve your spot now!

Shut Up & Write! Kingsdale Shopping Center
Greetings writers! Come down and join your fellow wordsmiths for one hour of uninterrupted writing time in the upper level of the Market District Supermarket in Upper Arlington.
The main entrance of the shopping center opens onto stairs/elevator leading up to the 2nd floor cafe section where we will have a table displaying a sign with the Shut Up & Write logo.
Writing is largely a solitary craft. Practicing with others in a community setting may be the thing you need to fire your own routine.
We’ll meet on Wednesday evenings, starting the clock at 6:30, following a brief period of introductions. This is solid writing time and all inclusive. Any project is acceptable, be it fiction, non -fiction, work or homework assignment. All is welcome and will remain private to you.
The market boasts a Starbucks, a full service bar and various affordable food options. Parking is plentiful, free Wifi is provided as well as outlets for charging your devices, though they are somewhat limited, so plan accordingly.
Show up as early as you like, or stay late. This group tends to socialize some, both before and after the alloted time, but this is not mandatory to you. Feel free to come and go as you please and late arrivals are welcome.
The cafe may be noisy on occasion so headphones/ earbuds are reccommended as you see fit.
Please try to RSVP if possible so that we may grab enough seats for all—the venue can be busy at times.
Feel free to message me privately wth any questions and/ or concerns you may have.
Happy writing!

This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us.
COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

Session Abstract
### Data Cleansing using Data Bricks
Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure.
\*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.
