Science

For millennia humans have worked with their dreams - lucidly, prophetically, and pragmatically - to uncover their deepest desires, fears, and hidden knowledge. Serving as a portal to the psyche during sleep, dreams are a powerful tool for revealing the subconscious, hinting at a greater mystery simmering just below the surface of waking life. Are they messages from the gods - as believed by the ancients, who dedicated sacred temples and rituals to the art of dreaming? Or are they simply psychological processes, as presented by great modern thinkers like Freud and Jung? In this salon we explore the world of dreams and how intentional dreamwork can help us uncover our inner worlds and integrate our waking experiences. Through a mix of discussion and practical exercises drawing on both ancient dream practices and modern science-based methods, you will gain a greater understanding of how to evoke, remember, and interpret your dreams - and the hidden messages they have been waiting to reveal. Door open at 7, event starts at 7:30 pm. We will have light refreshments, wine, beer, and non-alcoholic beverages available for purchase. Tickets are 15 € via pre-registration ([link here](https://rausgegangen.de/en/events/mystery-salon-at-lilium-dreamwork-inner-worlds-0/)) or 20 € at the door. We recommend bringing a notebook or journal.

Berlin, die Stadt der 1000 Möglichkeiten ... ich kenne das auch. . **🌸 Dann machen wir einen Workshop!** 1. Maximal 40 Frauen. 2. Eine leichte Moderation führt durch den Abend 3. Ihr lernt Euch kennen und habt Spaß. 4. Wer mag, trifft sich wieder. . Du wirst überrascht sein, wie vertraut Du mit vielen nach 3 Stunden sein wirst - so, als ob Ihr Euch schon lange kennt. . **🔱 4 Jahre Arbeit - 1 Workshop** Vier Jahre habe ich geforscht und ausprobiert, wie Menschen Freunde werden & was die Magie der Freundschaft ausmacht. Das Ergebnis ist dieser Abend. . Praxisnahe, schnell umsetzbare Tipps, die Du schnell in den Alltag umsetzen kannst. Kleine Happen zur Theorie. - Und vor allem: Kennenlernen & Spaß haben. Wir probieren einfach miteinander aus. . Eine Teilnehmerin sagte mal zu mir: * "Georg, das ist so eine angenehme Atmosphäre. Danke, dass Du das machst." . Was soll ich sagen? Stimmt.

Abenteuer Freundschaft ist mein Beruf. Am Anfang war ich auf Männer-Freundschaften spezialisiert. Überraschenderweise waren 60 Prozent der Newsletter-Empfängerinnen Frauen. Frauen scheinen die Wichtigkeit guter Freundschaften viel mehr zu spüren. . Deshalb habe ich letztes Jahr angefangen, Workshops für Frauen anzubieten. Soziale Träger, das Rathaus Schöneberg und das Frauenzentrum Begine haben mich bereits für Freundinnen-Workshops gebucht. Im Frauenzentrum moderiert eine Bekannte die Workshops.... denn da darf ich noch nicht mal rein :). . Unseren Workshop werde ich zurückhaltend moderieren. Ich weiß mit der Situation umzugehen.

​Artificial intelligence is evolving at an extraordinary pace and is already reshaping how we work, learn, create, and make decisions. Some see AI as a powerful tool that will enhance human potential and solve global problems. Others warn about risks: bias, automation, loss of control, and long-term societal impact. ​In this meeting, we will explore AI from both perspectives — techno-optimism and techno-pessimism. What can AI actually do today? How does it work under the hood? Where are its real strengths, and where are its limitations? And how should we think about its future development? ​We invite both professionals and non-professionals to join the discussion. Whether you work with AI, study it, are simply curious about it, or approach it from philosophy, psychology, sociology, or everyday experience — your perspective is welcome. ## **​Preparation & Suggested Materials** ​To help you prepare, we’ve put together a curated reading list that includes books, research papers, articles, interviews, and practical guides. The world of AI moves fast, so alongside well-known books you will also find recent articles and research projects. ​You don’t need to read everything. Choosing one book, article, or even a short explainer is enough to take part in the discussion. You’re also welcome to bring your own material, as long as it relates to artificial intelligence and its societal impact. ​The full list of suggested readings (with links) is available here: ​[https://docs.google.com/document/d/17PoZmqzxQ5EJsET292lTI193ms_MZNvgv5XAnbVmRBY/edit?usp=sharing](https://docs.google.com/document/d/1Hu_dLOgnzvrfgE3CZQVBz6CqyPIgAMWxYE24o4yx3fQ/edit?usp=sharing&utm_source=luma) ***​Popular-Science Books*** ​Accessible but substantial books that explain how AI works and how it affects society. For example: * ​*Co-Intelligence* by Ethan Mollick * ​*Hello World* by Hannah Fry * ​*Artificial Intelligence: A Guide for Thinking Humans* by Melanie Mitchell * ​*Homo Deus* by Yuval Noah Harari ​***Scientific & Popular Articles*** ​Shorter texts for those with limited preparation time. These include: * ​A brief history of AI (Haenlein & Kaplan) * ​“On the Dangers of Stochastic Parrots” (Bender et al.) * ​Stephen Wolfram’s explainer on how ChatGPT works * ​Andrew Ng’s “AI is the New Electricity” ​***Real-World Applications & Practical Guides*** ​Materials for those interested in applied AI: * ​KDnuggets blog (case studies and practical use) * ​*Deep Learning Illustrated* * ​Google’s Prompt Engineering Guide ***​Research Projects*** ​For a forward-looking perspective: * ​Epoch AI * ​AI 2027 scenario ## **Important Information** ​​We aim to create a safe, inclusive space for sharing ideas and learning from different perspectives. Respectful dialogue is encouraged, and participants are asked to follow our **[Code of Conduct](https://docs.google.com/document/d/1zhC3yhSvmAoO4wx5TlEmW-oyxs5FhCXN7MD0f0I_SAc/edit?tab=t.0&utm_source=luma)**. * ​​**Age 16+** * ​​The discussion will be held **in English.** * ​​**Registration is required** to attend the event. * ​​Participation is free. Donations are optional and help support our meetings.

**Labor: Past, Present, and Future – Work, Power, and Purpose** Labor is a defining force of human life. It shapes how we survive, how societies are organized, and how power and resources are distributed. Work can provide stability, dignity, and meaning—but it can also lead to inequality, exploitation, and exhaustion. More than just an individual experience, labor is a collective reality that reflects the structure of our world. At its foundation, labor is tied to survival. Like all living beings, humans must expend energy to sustain life. Our bodies and minds are wired for effort, cooperation, and problem-solving. Yet human labor goes far beyond biology—it is structured by economic systems, cultural values, and political decisions that determine who works, how, and for whose benefit. Across history, labor has continuously evolved—and so have the struggles surrounding it. Workers have organized to demand rights, protections, and fair wages, giving rise to unions, movements, and political parties. In many countries, labor movements shaped modern democracy, from the Social Democratic Party of Germany in Germany to the Labour Party in the UK, alongside similar movements across Europe and beyond. These efforts are remembered and celebrated globally on Labor Day. Labor is not only a human phenomenon. In the natural world, cooperation, division of roles, and collective effort are essential for survival—from insect colonies to social mammals. These systems offer a broader perspective on work as something deeply rooted in life itself, while also highlighting what makes human labor unique: its complexity, inequality, and capacity for change. In today’s world, labor is undergoing rapid transformation. Automation, digital platforms, and globalization are reshaping traditional employment. Stable careers are giving way to flexible—and sometimes precarious—forms of work. At the same time, the psychological experience of labor is becoming more visible: questions of burnout, motivation, identity, and purpose are central to how people relate to their work. Looking ahead, the future of labor may challenge long-held assumptions. Artificial intelligence and robotics could significantly reduce the need for human labor in many sectors, while increasing demand in others. This raises fundamental questions: What is the role of work in human life? How should wealth be distributed? And how do we define purpose in a world where labor is no longer central to survival? We will explore how labor has evolved through history—from early forms of work to modern economies—and how worker movements and political forces like the Social Democratic Party of Germany and the Labour Party shaped rights and social change. We’ll also reflect on labor as a biological, psychological, and social experience—how effort, motivation, and cooperation shape both humans and the natural world—and how work today is being transformed by technology, from gig economies to automation. Finally, we’ll look ahead to the future of labor, asking what happens if work changes fundamentally, and how we might rethink purpose, fairness, and the role of labor in our lives. Join us for a critical and engaging discussion on labor—not only as work, but as a force that shapes society, identity, and the future. Together, we’ll reflect on how labor defines our lives today and how it might be reimagined tomorrow. *** 📅 Event Details 🗓️ Date: Saturday, 18 April 2026 ⏰ Time: 14:30 📍 Location: Hardenbergstraße 10, 10623 Berlin 📱 WhatsApp: For prep materials and directions (Group Chat) [Group Chat](https://chat.whatsapp.com/Ba8ZAaH2Yuk6FGmD3LLO7H)
