[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Love Lecture,”** a contemplation of matters of the heart, with Laura Papish, associate professor of philosophy at George Washington University and teacher of a seminar on the philosophy of love, sex, and friendship. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture](https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture) .] Who wrote the book of love? Why does love have to be so sad? Is it a thin line between love and hate? On a more serious note, how does our society's understanding of love and romantic love shape our experience of it? Why do we think of love as mysterious and irrational? Do those we love need to be lovable? Is love necessarily a morally good thing, or can it actually make it harder for us to be good? Show your love for learning by hearing such questions tackled by Laura Papish, who has built a considerable following among Washington D.C. fans of Profs and Pints with her annual talks exploring the intersection of the brain, the soul, and the heart. Hilariously accompanied by her husband, Chris (on guitar), she’ll offer up a delicious assortment of thoughts about the upcoming Valentine’s Day holiday—some dark, some sweet, and some giving you plenty to chew on. Dr. Papish will start by examining how ancient Greeks thought about erotic love and move on from there, looking at how love is envisioned in modern thinkers, classic novels, recent films, and pop culture. She’ll also discuss the origins of the idea that people have a “soul mate” and how some thinkers have tried to criticize or transform the very concept of love. Together, we'll explore different possibilities for love and those mysteries about it that have left more than a few of us feeling befuddled. Feel free to show up if you are lovelorn, love-stricken, or just love to hear a fascinating discussion. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Everyone’s prompting. Few people are judging. This talk shows how a playwright uses multiple LLMs and vibe coding to build a custom evaluation loop: a digital dramaturg that checks scenes against an outline like a living spec. If you design, build, or eval AI systems, you’ll leave with a new mental model for using LLMs as QA, not just content engines. **Featured speaker:** * [Soo-Jin Lee](https://www.linkedin.com/in/soo-jinlee/)\, Gen AI Conversation Designer \| Prompt Engineer \| LLM\, NLU\, NLP \| Human in the Loop \| Former Teacher \| Playwright **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** --> Alamo Drafthouse, 1660 Crystal Dr, Arlington, VA 22202 (2nd Floor) **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac , member of QPoland Zoom registration form will be provided no later than 1 hour prior to the event's start time.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

Wouldn’t it be nice to find a way to overcome your feelings of anger so that you not only control them, but you no longer have the urge to lose your temper in the first place? And how about being able to shake off resentments, persistent annoyance, or even feelings of vengeance? We’d like to invite you to an event on how to overcome anger and resentment. We will show you why people have trouble controlling their temper and where resentment comes from. Flaring anger can ruin a meeting, a relationship, an opportunity, or just about any aspect of life. Worst of all, outbursts towards our family can create hurt that lingers throughout a lifetime. You want to have a civil conversation, and you’ve vowed that you wouldn’t lose your temper, but a few minutes later, the anger flares up. Maybe you’ve realized that being angry doesn’t get you what you want so you internalize it. Or maybe you avoid the knockdown, drag-out fights, but stewing in resentment is exhausting and takes an emotional toll. In this event we show you how to get to the root of your anger so that it stops being an issue to you. You’ll also learn why people harbor resentments and how to move on. Don't continue to struggle, make a difference in your life, and join us for this local event. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This Meetup is sponsored by your local Dianetics and Scientology Life Improvement Center.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)
