Join us for Python Project Night! Project Nights are informal gatherings where attendees can bring their own projects and work together (or just next to each other). We'll have at least one experienced Python web developer on hand to help less experienced people with their projects. We host these project nights each month in addition to our normal talk meetups. Agenda • 6:30-7:00pm - Arrive, eat and catch up (thank Chief (http://agencychief.com/) for the food!) • 7:00pm-8:45pm - Coworking What could you do at project night, you ask? • Work on your own side projects with other people doing the same • Get help learning Python (or Django or Flask) from more experienced developers. (Or, help mentor other attendees if you're already a whiz) • Ask for a code review for a project you've been working on by yourself • Talk through a particular problem with someone who has solved it before • Just hang out and have some cool conversations! We are cross-listing this event with DC Python, so please RSVP to only one so we can get an accurate headcount.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Our Bodies, Our Minds,”** an exploration of the relationship between our biology and our thought processes, with Justin Brooks, M.D., associate professor of computer science and electrical engineering at University of Maryland, Baltimore County and scholar of computational psychophysiology. [Advance tickets: $13.50 plus sales tax and processing fees. Available at h[ttps://www.ticketleap.events/tickets/profsandpints/dc-bodies-minds](ttps://www.ticketleap.events/tickets/profsandpints/dc-bodies-minds) .] For millennia, humans have wondered how mind and body are connected. Are our thoughts just the electrical murmurs of nerve cells, or is there something more? Are they the result of millions of years of evolution? Explore the mind-body problem through the lens of measurable physiology with Dr. Justin Brooks, a physician-scientist whose research focuses on using mobile and wearable technologies to understand, predict, and influence human behavior and health. He’ll describe how millions of years of evolution shaped the way our minds and bodies speak to each other, with our nervous system being the product of countless adaptations that shape how we react, think, and survive. Reflexes hidden in our physiology, attention, and mental effort reveal a “biotype,” a stable but adaptable signature of how we process the world. The problem is that reflexes honed by a prehistoric world of predators and scarcity now must navigate the strange demands of a modern society. Rather than mirroring who we truly are, our reflexes often are just echoes of ancient survival needs. As a result, many of us live slightly out of sync with our own biology. We think faster than we feel, ignore our body’s quiet warnings, and misread the signals from our bodies that guide balance and well-being. Breakdowns in the conversation between mind and body cause stress to accumulate, performance to falters, and health to erode. In a talk that blends neuroscience, physiology, and philosophy, Dr. Brooks will discuss how our specific biotypes might hold clues for realigning our ancient wiring with the pace of contemporary life to avoid the pitfalls of burnout, chronic stress, and mental fatigue. He’ll explore how measuring the body can illuminate the mind and how both can be brought back into harmony for the world we live in now. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Title: An Easy Intro to Feynman's Quantum ElectroDynamics (QED) Summary: One of the most delightful and informative physics books ever written is Richard Feynman’s QED. In this short book, Feynman undertook the daunting task of explaining his Nobel-Prize-winning theory, Quantum ElectroDynamics, without any math except in a few elaborating footnotes. Remarkably, he succeeds! In this talk, Terry replicates many of his arguments to show how you, too, can understand one of the most fundamental mechanisms of physical reality by using not much more than lots of tiny one-hand clock dials moving through space. Speaker: Terry Bollinger is a computer scientist Speaker: Terry Bollinger is a computer scientist with BS, MS and Professional degrees from the Missouri University of Science and Technology.
