Zur Aktionswoche gegen Einsamkeit des [Kompetenznetzwerks Einsamkeit ](https://kompetenznetz-einsamkeit.de/aktionswoche)veranstalten wir von [platoniq.health](https://www.platoniq.health/de) ein kostenloses und unverbindliches Walk & Talk Format. Begleitet von kleinen wissenschaftlichen Einblicken und psychologischen Impulsen spazieren wir gemeinsam im Treptower Park und tauschen uns über das Thema Freundschaft und Einsamkeit aus. Eingeladen sind alle, die sich für das Thema soziale Beziehungen interessieren.

**If the event is fully booked, feel free to join us at the meeting point.** A participatory urban walk exploring memory, monuments, architecture, and hidden narratives in public space through observation, storytelling, and photography. We will move slowly along Karl-Marx-Allee, treating the city as a layered archive of perception. Through guided observation exercises and short reflective prompts, participants are invited to explore how urban space is read through personal experience, collective memory, and everyday traces. This is not a tour, but a collective reading of the city. No prior experience required. **Materials:** smartphone, paper, pen, optional audio recording **Participation:** Participation by voluntary contribution (5–15 € suggested) **Meeting point:** Karl-Marx-Büste (https://de.wikipedia.org/wiki/Strausberger_Platz#Karl-Marx-B%C3%BCste), Berlin ([Strausberger Pl. 12, 10243 Berlin](https://maps.google.com/maps?vet=10CAAQoqAOahcKEwi4l8-__c-UAxUAAAAAHQAAAAAQJg..i&sca_esv=080e5c4976d32afe&pvq=OhUweDA6MHgzOWMxOWFkN2Y5ZDg2ZTY&fvr=1&cs=0&um=1&ie=UTF-8&fb=1&gl=de&sa=X&ftid=0x47a84e3e065a95dd:0x39c19ad7f9d86e6)) **Collective Archive (optional contribution):** Participants are invited to contribute to a shared archive of the walk: Upload here: https://padlet.com/denkmallab/Building_Stories_Memory_Walk_Contributions Contributions are voluntary and may include photos, notes, or audio fragments from the walk and are part of a collective open research experiment

Join us for our second hike of the summer! We will start by meeting at (or at least boarding) the **10.40 RE2 (3112)** at **Ostkreuz** station, **Platform 13.** We will arrive at Lübben (Spreewald) at 11.25. *Note that if you miss this train, then the next one does not arrive until 11.56, so you will certainly miss us and won't be able to catch up!* The hike will go from Lübben to Schlepzig, along the canals and lakes of the beautiful Spreewald region. *(See photos for a rough route -- this is not necessarily accurate!)* The walk will be about 15 km and take about 4-5 hours. Bring lunch, snacks & water, comfortable walking shoes, and maybe even some sunglasses. We will stop a couple of places along the way, but will not stop long enough to order food, so bring your lunch! At the end of the walk, in Schlepzig, there is a Whisky brewery and a Biergarten. We will visit one or both. You can also get food at both. Then, we will take the 18:57 bus back to the starting point of Lübben Bahnhof. From there, we will catch the 19.34 RE2 (3129) back to Ostkreuz, arriving at 20.23. *(If you really want to, and if we get to Schlepzig in time, then you can also take the 16.52 bus to Lübben, then the 17.34 RE2 back to Berlin.)* **Note: We will reschedule this if the weather is too rainy. So definitely check back here before going!**

We talk about **comics**! Graphic novels, graphic non-fiction, comic strips, superhero comics, manga - all types of comics are welcome. **Bring a comic book that you are currently reading or one that you want to talk about** (either a physical or digital copy). If you read comics on your tablet, then bring your tablet with you. If you haven't read anything recently (life gets in the way, we know), then feel free to come for comic recommendations. Looking forward to seeing you there!

This week we are discussing **Tove Ditlevsen:** Childhood, Youth, Dependency (The whole trilogy). We look forward to seeing you! If you have book suggestions, would like to vote on our next reads, or join us for additional activities, please ask someone at the meeting to add you to our WhatsApp group. Just a heads up: **The cafe only accepts card payments for amounts over €10**, so you may want to bring some cash for smaller orders. **Also, if you're unable to attend, please update your RSVP so that someone from the waiting list can take your spot.**

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

We meet and sketch each other in Berlin. This is just an art gym that we also exercise our social skills. Afterwards usually we go for lunch as a group. **How Does It Work?** This event is simple, we meet and sketch each other doing portraits. Most of the participants use pencils or watercolors. Main aim is to socialize while we draw. There will be plenty of time to talk and get to know each other. We have to mention that this event is suitable for all levels. Many have started to draw in our event actually. **Structure** A. Warmup Phase: We pose to each other for 1 minute. B. Main Phase: We pose to each other for 10 minutes. C. Showcase Phase: We show some of the drawings we did to each other. **Who We Are** Creative Sessions is an art events group located in Berlin. **Is it Free?** The event is free of charge. It is advisable to get a drink though. This is a cafe, we need to have at least half of the people on each table with a drink. They accept only cash and most hot drinks cost from 2.50 to 3.50. **How to help or donate?** The event is provided for free but many people help this be a regular thing. We also need people to volunteer and help for minor tasks like the serving of the drinks or cleaning up. Just send us a message.

**🐈‍⬛️ Why 3D Origami? Isn't all origami kinda 3D?** While regular origami is made by folding one piece of paper into a complex shape, 3D origami uses identical modules stacked on top of each other to create larger objects. In this meetup you will learn how to fold basic 3D Origami pieces to create either a flower🌺 or a chick 🐣 model. If you want to look beyond traditional origami techniques, this meetup is for you! No prior experience required. What you can expect in our events: ***Mandatory donation (amount of your choice) **– this supports essential costs like the Meetup subscription and keeps our community thriving. 🌱 You can either submit a physical donation to the event host in person or make a digital donation [here](https://paypal.me/origamiberlin?locale.x=de_DE&country.x=DE) (and inform the host afterwards). ** *Please order at least one drink/snack **to support Hermann Eicke for hosting us!** *** In-person folding practice for all levels *– beginners and experienced folders are equally welcome.* *** Origami paper + model instructions will be provided.

Whether you’re a regular or joining us for the very first time, come along to enjoy an iced coffee, play some light board games (no competition stress), and meet new people in a relaxed, friendly atmosphere.

You can sleep in on the Semiquincentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.
