[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The History of Plastic Surgery,”** with Dr. Wendy Chen, plastic, reconstructive, and hand surgeon and assistant professor at the Johns Hopkins School of Medicine. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery](https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery) .] Most people misunderstand plastic surgery as vain and aesthetic, but the origins of this fascinating specialty are much deeper than that. Come gain a rich understanding of the roots, medical impact, and current wide reach of a life-altering medical specialty with Dr. Wendy Chen, a leading educator on plastic and reconstructive surgery who has won awards for her work in clinical, basic science and education research. She’ll talk about how reconstructive surgery has been around for thousands of years, with evidence of it having been practiced in ancient Egypt and India, and has made advancements in the course of major wars. Those who practice it have been innovators in medicine, playing a major role in breakthroughs and winning the Nobel prize for kidney transplantation. The need for plastic and reconstructive surgery has stemmed largely from how much our appearance influences how we navigate our worlds and how others regard us. There was a time, in fact, when people in American prisons were offered plastic surgery as an intervention against recidivism. Yet reconstructive surgery also has faced opposition, such as religious bans on its practice stemming from the belief that physical differences are a manifestation of spiritual sin. Fast forward to now when plastic surgeons treat patients of every age for every kind of ailment, from congenital differences to trauma to cancer. Yes, some plastic and reconstructive surgery is to help people conform to tabloid- and social media-driven narratives of what defines beauty, but the field involves a lot more than injecting Botox and shaping buttocks. ( Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“What Digital Detectives Find,”** on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives) .] What happens when you delete digital data such as a picture, video, or email message? The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever. Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years. You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered. Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not. Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: A digital forensics examiner works with evidence in the FBI’s New Jersey Regional Computer Forensics Laboratory (FBI photo).

What Happened to the Energy Transition? To land a ship on a moving target, the moon, for example, from a moving object, the earth, requires an enormous attention to facts and a mastery of detail. Getting any of these wrong can lead to disaster. Climate science tells us we must transition to a zero carbon society—and fast. But are climate-deniers the only obstacle to that transition? We will discuss the work of economic historian Jean-Baptise Fressoz who suggests that even as we move to solar panels and electric vehicles, rather than “transitioning” to a zero carbon world we will continue to consume more, and more, and more and produce more carbon dioxide. Is there a way out of here? As harrowing as it sounds, its best to pay attention to the facts and master the details so we can discuss real solutions. Perhaps, a solution that depends on a transition in our ethical thinking. In-person and available on Zoom When: Sunday, April 12, 2026 Coffee available at 10:45 AM, Speaker begins at 11:00 AM Where: Green Hedges School 415 Windover Ave NW, Vienna, VA It's more fun in person (and the coffee is free), but you can participate by [Zoom](https://us02web.zoom.us/j/85147568797?pwd=2TQNpZPubvub435R7H9cEaKWrTWgaS.1) Jim Ball and his family are longtime members of Ethical Culture.

This will be our second (and possibly last) meeting on *Nature's God: The Heretical Origins of the American Republic*, by Matthew Stewart. For this meeting, please try to read chapters 4 and 6. (You can skim chapter 5, which is particularly confusing). **Where did the ideas come from that became the cornerstone of American democracy?** America’s founders intended to liberate us not just from one king but from the ghostly tyranny of supernatural religion. Drawing deeply on the study of European philosophy, Matthew Stewart brilliantly tracks the ancient, pagan, and continental ideas from which America’s revolutionaries drew their inspiration. In the writings of Spinoza, Lucretius, and other great philosophers, Stewart recovers the true meanings of “Nature’s God,” “the pursuit of happiness,” and the radical political theory with which the American experiment in self-government began. [LINK](https://a.co/d/bkTWJNb) This book is not always an easy read. You may want to make use of AI tools such as ChatGPT. You can ask it questions like: "What does Matthew Stewart say about happiness in his book Nature's God?" OR: What does Matthew Stewart say about Spinoza? This may be our last meeting on this book. If you want to have a third meeting later, on the last two chapters, let me know. I hope to see you there! Fred

If you are new to the community of Alexandria and want to meet like minded folks or a veteran of it, this is a special and unique opportunity and did I mention it is free? :) Hard to believe! Please join me every Sunday at 945 am.

Curious about “vibe coding” but not sure what it actually means? This beginner-friendly talk is about how people are using AI to build websites, apps, automations, and small software projects by describing what they want in plain English. We’ll cover what vibe coding is, what AI is good at, where it falls short, and how to actually use it without getting lost. The goal is not to hype AI as magic — it’s to show how to use it as a practical tool. This session is designed for beginners, curious builders, non-programmers, and developers who want a clearer picture of how to build with AI today. Topics include: * What “vibe coding” means * What AI can help you build * Where AI is useful and where it is unreliable * A simple workflow for building with AI * Prompting tips for better results * Common beginner mistakes to avoid If you’ve ever thought, “I have an idea, but I don’t know how to build it,” this talk is for you. 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.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
