Public Lectures Unveiling Math (PLUM)
Department of Mathematics Duke University 
The PLUM lecture series are aimed at general audience and focused on promoting mathematics in general by presenting inspiring stories about mathematics. They could be based on an incredible journey for finding fundamental truths or could be about how mathematics is used for real world applications. The PLUM is supported by the iiD, by the Department of Math, by the Department of ECE, and by Duke Undergraduate Math Union.

Title: Ramanujan's Life, His Earlier Notebooks and His Lost Notebook
Abstract: Ramanujan was born in southern India in 1887 and died there in 1920 at the age of 32. He had only one year of college, but his mathematical discoveries, made mostly in isolation, have made him one of the 20th and 21st centuries' most influential mathematicians. An account of Ramanujan's life will be presented. Most of Ramanujan's mathematical discoveries were recorded without proofs in notebooks, and a description and history of these notebooks will be provided. In 1976, George Andrews found Ramanujan's "lost notebook" in the library at Trinity College, Cambridge. A history and description of this lost notebook will also be provided. The lecture will be accompanied by photographs of Ramanujan, his home, his school, his notebooks, and those influential in his life, including his mother and wife Janaki.

Title: A world from a sheet of paper
Abstract: Take a sheet of paper. By folding, stacking, crumpling, tearing, we will tour a rich diversity of phenomena, from geometry and magic tricks to elasticity and the traditional Japanese art of origami. Much of the lecture consists of actual tabletop demos, which you can try with family and friends. So then, take a sheet of paper.

Title: A glamorous Hollywood star, a renegade composer, and the mathematical development of spread spectrum communications
Abstract: During World War II Hedy Lamarr, a striking Hollywood actress, together with George Antheil, a radical composer, invented and patented a secret signaling system for the remote control of torpedoes. The ideas in this patent have since developed into one of the ingredients in modern digital wireless communications. The unlikely biography of these two characters, along with some of the more modern developments in wireless communications will be described.

Title: How to Bake π, Making abstract mathematics palatable
Abstract: Mathematics can be tasty! It is a way of thinking, and not just about numbers. Through unexpectedly connected examples from music, juggling, and baking, I will show that math can be made fun and intriguing for all, through handson activities, examples that everyone can relate to, and funny stories. I'll present surprisingly highlevel mathematics, including some advanced abstract algebra usually only seen by math majors and graduate students. There will be a distinct emphasis on edible examples.

Title: Voting in Agreeable Societies
Abstract: When does a candidate have the approval of a majority? How does the geometry of the political spectrum influence the outcome? What does mathematics have to say about how people behave? When mathematical objects have a social interpretation, the associated results have social applications. We will show how some classical mathematics can be used to understand voting in "agreeable" societies. This talk also features research with undergraduates.
