This week we'll discuss the sixth chapter of [The Science of Can and Can't](https://www.amazon.co.uk/Science-Can-Cant-Physicists-Counterfactuals/dp/0241310946/ref=sr_1_1?crid=1YFBGHPLNB4NO&dib=eyJ2IjoiMSJ9.YoSj1NdZXBPKK81RKKOjBA.ga2ZS1YEzf0cR13hyK4BpEHaXtvmjSfEhGZemtNXrLU&dib_tag=se&keywords=the+science+of+can+and+can%27t&qid=1779107463&sprefix=the+science+of+can+and+can%27t%2Caps%2C136&sr=8-1), by Chiara Marletto, co-developer of Constructor Theory alongside David Deutsch. This is the second of two discussions on this chapter. A big theme of the book is counterfactuals - statements about what *could* happen, not just what *does* happen. Chiara argues that science has historically struggled to incorporate these rigorously, even though they’re central to explanations, computation, biology, knowledge, and agency. If this is your first time attending we meet in the cafe of the Barbican Cinema - look for people with copies of the book. Please read the chapter before attending.

In this session we will read aloud some of the Tractatus Logico Philosoophicus by Ludwig Wittgenstein, and discuss it. One of the most difficult books of philosophy ever written, it attempts in no more than 79 pages to set out the limits of language, knowlege and reality. Bertrand Russell described it as "an achievement of extraordinary difficulty and importance" and a work of "philosophical genius". No preparation or background knowledge required for the session. We will read together, share explanations where we can, and form our reactions. Gather in Highgate Library from 3.15, read and discuss 3.30 to 4.30. Optional socialising in the Boogaloo pub afterwards.

Pitch.london is a curated speed-networking event for founders, operators and serious builders. Short, structured conversations. Sharp prompts. Real chemistry, fast. The hardest problem in early-stage entrepreneurship is finding the right people. Most events leave it to chance. We don’t. The room is curated, the prompts are clear, and the format is built for high-signal encounters between people who are actually building something. In one evening, you can meet more relevant people than you might in months of random networking. Two formats. One room. Zero fluff. **01\. Founder matchmaking pitches** Sixty seconds to share who you are, what you’re building, and what would actually help right now. Whatever you’re looking for, the room is built to help you find it: people to build with, people to hire or be hired by, advisors and investors, or honest feedback on what you’re shipping. **02\. Group brainstorms** Small, time-boxed groups tackle a real challenge brought into the room. Bring a live problem you’re stuck on. Get five minds on it for ten minutes. Leave with new angles and next steps. **This room is for you if you’re:** * A founder seeking a co-founder * A founder seeking a first hire * An operator looking for a serious team to join * A technical builder open to commercial partners * A commercial builder open to technical partners * A second-time founder scoping the next thing * An angel investor close to the early-stage scene It’s probably not for you if you’re hunting for clients, selling services, or still working out what you’re looking for. **Run of show** * 17:30 to 18:00 Doors, drinks, soft start * 18:00 to 18:05 Welcome and the rules of the room * 18:05 to 18:35 Speed pitches: Round 1 * 18:35 to 19:15 Group brainstorms * 19:15 to 19:45 Speed pitches: Round 2 * 19:45 to 20:00 Open networking, then drinks at the citizenM Skybar **What’s included** Your £25 covers your seat in the room and a drink at the citizenM Skybar after the programme. **First 30 in get a seat**

Looking for a Sunday that feels like a soft slice of summer? Join us for a beautiful 12–15 km loop through the Darent Valley, where riverside paths, rolling green fields, and blooming lavender come together in one of Kent's most charming landscapes. This valley has been shaped by centuries of life and travel, and you feel it as soon as you step onto the trail. We'll pass beneath the towering arches of the Eynsford Viaduct, a Victorian engineering landmark that has carried trains across the valley since the 1860s. Further along, the route brushes past the historic grounds of Lullingstone Castle, a Tudor manor once visited by Henry VIII and home to the Hart Dyke family for over 500 years. From there, the path opens into the quiet lanes of Shoreham village and the purple shimmer of the lavender fields drifting across the hillsides. As we move through meadows, woodlands, and open countryside, the day settles into that easy summer rhythm where everything feels unhurried and lightly golden. It's the kind of walk where the scenery does the talking: the river winding beside us, the scent of lavender in the warm air, and the countryside unfolding in soft greens and purples — a Sunday that feels sun-warmed, peaceful, and just a little bit dreamy. We will head to a pub near the station when we finish for a pint or/and lunch. ## 📅 **Event Details** **Meeting Point:** Eynsford Station (Start / Finish) **Meeting Time:** 10:15 AM for 10:30 AM sharp start. **Distance:** approx. 12 to 15 km **Elevation:** \~300 m approx **Difficulty:** Moderate **Pace:** Steady **Estimated Finish:** Around 2 PM ## 🌿 **Route Highlights** * **Eynsford Viaduct Viewpoint** — one of Kent’s most photogenic spots, especially in summer light. * **Ancient woodland paths** around Ashen Bank, offering shade and cool forest air. * **Shoreham Village** — postcard‑perfect with its stone bridge and riverside charm. * **Darent Valley Path** — peaceful riverside walking with open fields and gentle breezes. * **Shoreham Lavender Fields** — with sweeping purple rows and great photo opportunities. * **Lullingstone Country Park** and **Castle** — meadows, woodlands, and a relaxed finish back toward Eynsford. This is a circular route full of **colour, greenery, and soft summer atmosphere** — the kind of day that feels wrapped in the easy warmth of summer countryside. ## 🎒 **What to Bring** * Comfortable hiking boots or sturdy shoes * At least **2L of water** * Packed snacks * Sun protection (hat, sunglasses, sunscreen) * Light layers — summer can still surprise * Good vibes and your best Sunday‑summer energy ## 📌 **Important Notes** * **Stay Together:** Please stay with or behind the hike leader to keep the group moving smoothly and regular catch ups. * **Respect the Area:** Parts of the route pass through the **Kent Downs National Landscape** — please respect wildlife, fields, and local guidelines. * **Group Rules:** Please read the “About Us” section before joining: [https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities](https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities?utm_source=copilot.com%20%22www.meetup.com%22) * **Safety:** This is a voluntary activity.

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.

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. 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.

Wild Thursday: THE INVITE on Thursday, July 9th at Cinemark Polaris! Join us as we get together to see the spicy and hilarious comedy-drama-romance from A24, THE INVITE! The film stars Olivia Wilde (who also directs) along with Seth Rogen, Penélope Cruz and Edward Norton, and follows a dinner party that spirals into unexpected places! Here’s a description, trailer and plan for this event: DESCRIPTION: Joe and Angela's marriage is on thin ice.

The film is an English language remake of the Spanish film The People Upstairs by Cesc Gay. It is directed by Olivia Wilde, who also stars alongside Seth Rogen, Penélope Cruz and Edward Norton. BUZZ & ACCLAIM: The Invite premiered to rave reviews at this year’s Sundance Film Festival and sparked an immediate bidding war to acquire it!
