12:00 PM - 12:55 PM Keynote - From Pi to Planets: Designing Humanity's Future in Space

Watch live in-person in CC 130 or watch live on YouTube

Space exploration is often presented as a triumph of rockets, equations, and advanced engineering, but the future of human spaceflight—over the next 20 to 100 years—will demand far more than technology alone. This keynote explores how space travel, space settlement, and planetary civilization are fundamentally human challenges that require contributions from every field of study. Drawing on examples ranging from high-altitude balloon experiments and rotating space habitats to AI-assisted lunar bases and the long-term vision of living on Mars, the talk shows how mathematical principles, physical constraints, and systems thinking shape our path beyond Earth, while also highlighting why artists are needed to visualize habitats; psychologists and medical doctors to safeguard mental and physical health; social scientists and political thinkers to design governance, cooperation, and conflict resolution; and sports and wellness specialists to keep future settlers healthy in low-gravity environments. Designed for Pi Day and a broad audience, the keynote invites students from all majors to see themselves as part of humanity’s next great journey and to recognize that the future of space belongs not to one discipline, but to all of us.

2:00 PM - 2:40 PM Calculus Workshop

Watch live in-person in CC 130 or watch live on YouTube

Workshop Title:
"The Science of Succeeding in Calculus”

Description:
Success in calculus is not about being a “math person,” but about developing specific, repeatable habits. In this workshop, we will explore what learning science and classroom experience suggest about how students actually succeed in calculus, including why studying longer is often less effective than studying strategically. Students will learn how to form productive study groups, how to prepare before and during the semester, and how to structure their time to build skill and confidence. Drawing from years of teaching experience and observed student outcomes, this session provides practical strategies that can be implemented immediately to improve performance and create a stronger academic foundation in calculus.

Title:
From Pollen to Pixels
How Einstein’s Math Powers Modern AI Models

Abstract:
Albert Einstein’s work on Brownian motion helped establish the existence of atoms and revealed how randomness at the microscopic level can produce predictable patterns at larger scales. In this interactive presentation, we explore how simple random motion leads to one of the most important equations in science: the diffusion equation. Beginning with the historical observations of botanist Robert Brown, students will investigate how scientists test hypotheses and eliminate possible explanations using careful experimental design.

Participants will then use an interactive web-based simulation to explore random walks, observing how unpredictable individual motion gives rise to clear statistical patterns. These experiments motivate an intuitive derivation of the diffusion equation using difference equations, illustrating how mathematicians “zoom out” from discrete systems to continuous models using calculus.

A second simulation will extend the ideas to two dimensions, showing how diffusion explains everyday phenomena such as the spreading of ink in water. The presentation concludes with modern applications of diffusion-based models, including the spread of disease, random fluctuations in financial markets, and recent advances in artificial intelligence such as diffusion-based image generation.

Abstract:
Have you ever wondered how Apple’s FaceID can recognize you even in the dark? That same technology will be explored in this interactive workshop but this time we’ll use it to detect Alzheimer’s by looking at brain waves! We will deep dive into the latest cutting-edge AI and medical technology. You’ll join in an interactive game of ‘Shuffle Attention’ - an AI strategy game where you’ll work in teams to filter out “background noise” and figure out hidden patterns in data. Come see how we’re teaching computers to “see” better and why a simple ‘shuffle’ is the secret to making AI faster and smarter.

Title:
How AI Learns and Generalizes: The Math Behind It

Abstract:
Artificial intelligence is rapidly transforming science, technology, and society, and much of this progress is powered by a remarkably coherent mathematical framework: deep learning. This talk introduces the core ideas behind modern neural networks from a mathematical viewpoint. We begin with supervised learning, where data come as input–output pairs and models map features to predictions. We then move from linear models to deep networks viewed as compositions of linear maps and nonlinear activations, and formulate learning as minimizing a loss function over training data. We highlight (stochastic) gradient descent and backpropagation—an efficient application of the chain rule—and briefly discuss key geometric aspects of the loss landscape, including local minima, saddle points, and the practical roles of noise and momentum. These ideas are illustrated through applications such as classification, large language models, and physics-informed neural networks (PINNs) that incorporate physical laws to address PDE-constrained problems.
