On Saturday, 27th of June, we’re going to meet and discuss the *The Power of the Powerless* by Václav Havel, an influential book that has become a key text of dissident thought in communist Eastern Europe. Written in 1978, Havel’s book explores how authoritarian systems sustain themselves not only through force, but through conformity, fear, and everyday participation in lies. What does it mean to ‘live within the truth’? Can ordinary people resist oppressive systems, even when they seem powerless? And what forms of responsibility do individuals bear in political life? Although written under late socialism in Czechoslovakia, Havel’s reflections remain strikingly relevant today. How do ideology, bureaucracy, media, and social pressure shape our behaviour? Are modern societies immune to the dynamics Havel describes – or do they simply take different forms? Václav Havel (1936–2011) was a Czech playwright, dissident, political thinker, and statesman. A leading figure of the democratic opposition during communist rule, he later became the last President of Czechoslovakia and the first President of the Czech Republic. *** Anyone is welcome to join! Before the meeting, please read the book (it’s around 100 pages long), think about it, and note any passages you find especially interesting, challenging, or worth discussing. We’ll share our thoughts and interpretations during the meeting. Organizational notes: 📍 Attendance is free ⏳ Spots are limited 🔗 Please register via the app so we know how many people to expect and can reserve a table accordingly

Filozofování o životě a o všem ostatním pro všechny, bez vstupného a bez přihlášky: Co si přejete, s čím si lámete hlavu, co Vás nenechá spát, o čem dumáte, o čem sníte, co Vám vrtá hlavou, čeho se bojíte, na co vzpomínáte, o čem přemýšlíte? Nenechte tyto věci jen pro sebe, zkuste rozhovor s jinými lidmi. U nás nejde jen o to, si popovídat, o to taky, ale to máte i jinde. U našeho stolu se pokusíme, spolu *filozofovat*. Nejdříve se dohodneme, jaké téma budeme diskutovat, a pak se do toho pustíme, budeme přemýšlet, rozmýšlet, promýšlet a zamýšlet se, až se nám z toho bude točit hlava, přitom nám budou podporou filozofové všech věků, abychom jí neztratili, tu hlavu. Ani byste nevěřili, jak filozofie může být osvěžující…

NOTE THE TIME CHANGE TO 9AM Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg

PLEASE NOTE: Due to the need of booking canoes in advance, your attendance of this event is only confirmed (!) when you reserve your place on DiscoveringPrague.cz website here: [https://www.discoveringprague.cz/event/lets-canoe-on-sazava-june-28-2026/](https://www.discoveringprague.cz/event/lets-canoe-on-sazava-june-28-2026/) Your RSVP "Going" here on Meetup is appreciated but won't guarantee you a spot. Thank you understanding & cooperation! \*\*\*\*\* Ahoj Discoverers! I’d like to invite you to another relaxing canoeing trip. This time on Sázava, the most popular Czech river. We will run a very scenic river section from Ledečko to the Sázava town, which is known for a monastery and the Kavalier glass-factory. *The trip is suitable for people who haven't canoed before as long as they can swim. You should also be somewhat physically coordinated and have patience to learn a new motor skill!* I'm NOT a certified instructor but I have taught countless people the basics of canoeing. DIFFICULTY: Easy to Medium (depending on the water level on the day) About 12 km / 8 miles. There are 3 weirs\* and some gentle rapids. \* A weir ('jez' in Czech) is a little dam regulating the flow of the river. LOGISTICS We will meet already at **7:45 AM (!)** in front of the main ticket office at the Prague Main Railway Station. We’ll be aiming to be back in Prague by 19:00. However, we will be as fast as the slowest member of our group and an unexpected delay is possible. This is a full-day event. WHAT TO TAKE WITH YOU • Shoes to wear in water (sandals, or you can buy special shoes for walking in water) • Wear clothes which dry fast (NOT jeans) • Sunscreen • Towel and maybe some spare clothes (in case your canoe capsizes) • Swimwear • Bottle of water and a small snack. • Put all your staff to a small compact bag – we will put all our belongings into water-proof barrels and they are not very large. You need to be prepared for a possibility of the boat flipping (capsizing). Keep your phone in a waterproof case and have glasses on a string while on the river! \*\*\*\*\* PRICE: 950 CZK (Includes train fare both ways, equipment rental and myself as your guide and organizer) Food&drink is not included. To be confirmed on the trip, you have to (!) book your place on Discovering Prague & CZ website here: [https://www.discoveringprague.cz/event/lets-canoe-on-sazava-june-28-2026/](https://www.discoveringprague.cz/event/lets-canoe-on-sazava-june-28-2026/) \*\*\*\*\* You can also pay with benefit cards or vouchers!

The topic for July is "Shoes" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!

**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.
