Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

Valentine's Day might be in the past, but Plato's classic discussion of love and desire, the *Symposium*, is eternal. Join us on April 4 to discuss this famous work, which features Socrates, Alcibiades, and other important Greek figures at a drinking party where things quickly turn philosophical. Feel free to bring whichever translation you prefer. As usual, we will meet in the Martin Luther King Jr. Memorial Library in the **205-B Accessibility Room**, located on the second floor. Ask at the Center for Accessibility front desk if you are looking for us. See you there!

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Semi in honor of March being International Women's Month Columbus libraries: [https://cml.bibliocommons.com/v2/record/S105C3454709](https://cml.bibliocommons.com/v2/record/S105C3454709) Location: SOW Plated Menu: [https://www.sowplated.com/menu-brunch/](https://www.sowplated.com/menu-brunch/) Book summary: In 2006 Julia Lerner is living in Moscow, a recent university graduate in computer science, when she's recruited by Russia's largest intelligence agency. By 2018 she's in Silicon Valley as COO of Tangerine, one of America's most famous technology companies. In between her executive management (make offers to promising startups, crush them and copy their features if they refuse); self promotion (check out her latest op-ed in the WSJ, on Work/Life Balance 2.0); and work in gender equality (transfer the most annoying females from her team), she funnels intelligence back to the motherland. But now Russia's asking for more, and Julia's getting nervous. Alice Lu is a first generation Chinese American whose parents are delighted she's working at Tangerine (such a successful company!). Too bad she's slogging away in the lower echelons, recently dumped, and now sharing her expensive two-bedroom apartment with her cousin Cheri, a perennial "founder's girlfriend". One afternoon, while performing a server check, Alice discovers some unusual activity, and now she's burdened with two powerful but distressing suspicions: Tangerine's privacy settings aren't as rigorous as the company claims they are, and the person abusing this loophole might be Julia Lerner herself. The closer Alice gets to Julia, the more Julia questions her own loyalties. Russia may have placed her in the Valley, but she's the one who built her career; isn't she entitled to protect the lifestyle she's earned?

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .
