Welcome to Carry the Two, the podcast about how math and statistics impact the world around us from the Institute for Mathematical and Statistical Innovation. While we’re in between our more in-depth seasons, we like to bring you something a little different in mini-season format. And for this mini season, we are going to highlight some of the amazing researchers who have presented at IMSI over the past year. Our second guest is Maria Chan,a scientist at Argonnne National Laboratory working at the Center for Nanoscale Materials who focuses on computational research involving materials in chemistry using a combination of physics, artificial intelligence and machine learning. Maria joined us at IMSI for a workshop on Machine Learning in Electronic Structure Theory where she presented a talk titled Theory-informed AI/ML for Microscopy & Spectroscopy. Host Sam Hansen joined Maria for a talk about the research in her talk and Maria’s time at IMSI.

Welcome to Carry the Two, the podcast about how math and statistics impact the world around us from the Institute for Mathematical and Statistical Innovation. While we’re in between our more in-depth seasons, we like to bring you something a little different in mini-season format. And for this mini season, we are going to highlight some of the amazing researchers who have presented at IMSI over the past year. Our first guest is Thibaut Mastrolia, an assistant professor at the Industrial Engineering and Operation Research Department at UC Berkeley Thibaut joined us at IMSI for a workshop on Decision Making and Uncertainty where he presented a talk titled Recent advances in auction markets design and regulation policies. Host Sam Hansen joined Thibaut for a talk about the research in this talk and how Thibaut’s time at IMSI has helped move it forward.

We in the United States are deep in the middle of a major national election, and over half of the world’s population also have elections in 2024. This is why Carry the Two is going to focus on the intersection of mathematics and democracy for our new season.

In this, the sixth and final episode of our mathematics and democracy season, we dig into both how surveys and polls are conducted and how they are reported. For the former we are joined by David Dutwin Senior Vice President at NORC and Chief Scientist of Amerispeak and for the latter by Nathaniel Rakich Senior Editor and Senior Elections Analyst at FiveThirtyEight.

In this episode, the fifth episode of our mathematics and democracy season, we dig into political numbers and statistics. Helping Sam and Sadie do the digging is Professor Sir David Spiegelhalter, FRS, OBE, emeritus professor of statistics at the University of Cambridge, former Professor for the Public Understanding of Risk at the University of Cambridge, past Chair of the Winton Centre for Risk and Evidence Communication, and current non-executive Director at the UK Statistics Authority. David discusses why it is so important to be a trustworthy communicator, the watchdog work the UK’s Office of Statistics Regulation is engaging in, and his personal manifesto for those who share political numbers and statistics.

In this episode, the fourth episode of our mathematics and democracy season, we dig into two stories about the intersection of political geography and mathematics. The first story comes from Ranthony Clark and is about her work with the Metric Geometry and Gerrymandering Group around identifying communities of interest, with a focus on her in Ohio alongside CAIR Ohio, the Ohio Organizing Collaborative (OOC), the Ohio Citizens Redistricting Commission, and the Kirwan Institute for the Study of Race and Ethnicity at Ohio State. The second story is about polling sites in cities, and the places in those cities that may not be covered as well as they should be. We hear from Mason Porter and Jiajie (Jerry) Luo, two members of the team, about how they used topological data analysis to find these holes in coverage.

In this, the third episode of our mathematics and democracy season, we speak to Andrea Mock, Gunnar Carlsson, Samin Aref, and Zachary Neal. We dig into what mathematics has to say about the stability of political coalitions, how mediators can make coalitions more stable, the ways in which Democrats and Republicans can be clustered together in the House of Representatives based on their votes, and the hidden third coalition of really successful legislators in the House that co-sponsorship data can illuminate.

In this episode, the second episode of our mathematics and democracy season, we speak again with mathematician Ismar Volić of Wellesley College and Director of the Institute for Mathematics and Democracy and Theodore R. Johnson, a scholar of Black electoral politics, a military veteran, and a contributing columnist at The Washington Post. We dig into what mathematics has to say about how the USA apportions members of the House of Representatives to states, learn how a fight between Jefferson and Hamilton over rounding led to the first presidential veto, and discuss different techniques for reforming the Electoral College.

IMSI is very proud to announce that Carry the Two is back and with a new co-host, IMSI’s new Director of Communications and Engagement Sam Hansen!

We in the United States are deep in the middle of a major national election, and over half of the world’s population also have elections in 2024. This is why Carry the Two is going to focus on the intersection of mathematics and democracy for our new season.

In this episode, the first episode of our mathematics and democracy season, we speak with mathematician Ismar Volić of Wellesley College and Director of the Institute for Mathematics and Democracy and Victoria Mooers, an economics PhD student at Columbia University. We discuss what mathematics has to say about our current plurality voting system, how switching to preference ranking votings systems could limit polarization and negative campaigning, and why too much delegation causes problems for those pushing for Liquid Democracy.

In this classic episode, we explore how GPT-3, a free online natural language processing artificial intelligence by Open AI, does and doesn’t work. Make sure to stick around until the end for an update on how AI is a core demand between the Writers Guild of America and the Alliance of Motion Picture and Television Producers.

GPT-3 takes advantage of a whole new method of artificial intelligence research, called neural nets, to create plays, write code, and even roleplay as a historical figure. But what are the limitations to this kind of AI? University of Chicago professor Allyson Ettinger walks us through how GPT-3 manages to sound so human and where and how it fails in interesting ways.
