2019-Jul-31 • 61 minutesRobert SchneiderThis episode is a bit of a blast from the past. Samuel has recently been going back through some of the old episodes from season 1 and while there were listening to The Score they realized that while the story about Robert Schneider and the non-Pythagorean scale was great it barely scratched the surface of amazing things Robert talked about in the interview. Upon registering to the original conversation, 7 years after it was recorded, Samuel realized not only did the story barely scratch the surface, the re... |

On this episode of Relative Prime Samuel Hansen is joined by the four co-creators of Mathematically Gifted & Black: Candice Price, Erica Graham, Raegan Higgins, and Shelby Wilson. Together they talk about why they wanted t... |

2019-Feb-28 • 49 minutes3 2 1…ActionHere on Relatively Prime we have discussed mathematical novels and poetry and music and even featured mathematics sketches, but we have yet to talk movies. That oversight is going to rectified on this episode by featuring two interviews Samuel had done with people who have made movies where mathematics is the star. First up is Samuel's conversation with the creators of the Flatland and Flatland² Sphereland animated movies writer and director Dano Johnson and the producer Seth Caplan Then you will here Sam... |

2019-Jan-31 • 18 minutesJem’s GemsOn Relatively Prime we talk a lot about mathematicians and their research, but it has been a long time since we have talked about an absolutely integral part of how people end up becoming mathematicians and doing research...Math Teachers. After all if there were no math teachers then who would first tempt us into the world of mathematics with wondrous things like factoring, which is totally what got Samuel hooked. Hey don’t look at them that way, they just love a good difference of two squares quadratic. On... |

2018-Dec-31 • 17 minutesA Year (1811) In ReviewIn a traditional move for the start of January we attempt a review of the year. In an untraditional move, we choose the year 1811. Samuel and Peter weren't able to speak directly because of the ongoing tension following American independence and the brewing Anglo-American war of 1812, but they cover some mathematical hot topics and the work of several contemporary mathematicians, including Carl Friedrich Gauss, Joseph Fourier, Mary Sommerville, Joseph-Louis Lagrange, Pierre-Simon Laplace, Siméon Denis Poiss... |

2018-Jan-31 • 26 minutesScience Sparring SocietySamuel has been feeling a bit nostalgic recently and was thinking about an old show we can almost guarantee you have never heard of, called Science Sparring Society. It was all based around this idea that from a Frank Swain tweet to make a podcast that told the stories of fights from the history of science. It was so much fun making this show, and Samuel was always sad that more people did not get the chance to hear it. Which is exactly why this episode features the two mathematical fights from the 2012 pod... |

2017-Dec-22 • 33 minutesFormulaic PerfectionWe are happy to bring to you a special holiday episode of Relatively Prime during this festive period. Samuel is joined by old pals Katie, Peter, and Christian from the Aperiodical for an often funny, sometimes serious, and always entertaining conversation about the phenomenon of formulas for "The Perfect X" which are often seen in newspapers, especially around the holidays. Some of the examples discussed were the perfect Christmas song, perfect Christmas tree, perfect penalty kick, perfect scone cream rati... |

2017-Nov-30 • 16 minutesCold and FluIt is that time of year where you, and everyone else, is coughing and sniffling and sneezing and generally getting gross germs all over the place. That is why for this episode of Relatively Prime Samuel Hansen speaks with Benjamin Morin about infectious disease modeling and the best mitigation strategies those models indicate to deal with disease while minimizing cost, both for individuals and for societies. Fair warning, those best strategies may be depressing and definitely not what Samuel was hoping for.... |

2017-Oct-31 • 20 minutesKnotty HelixSure DNA is important, some might even claim it is absolutely integral to life itself, but does it contain any interesting math? Samuel is joined by UC-Davis Professor of Mathematics, Microbiology, and Molecular Genetics Mariel Vazquez for a discussion proves conclusively that mathematically DNA is fascinating. They talk about the topology of DNA, how knot theory can help us understand the problems which occur during DNA replication, and how some antibiotics are really pills of weaponized mathematics. |

2017-Sep-29 • 34 minutesTheir Favorite TheoremHave you ever wondered what mathematicans' favorite theorems were? How about what food or music pairs perfectly with those theorems? Well whether your answer to those questions was yes or no or what are you talking about there is a new mathematics podcast on the scene you need to check out called My Favorite Theorem. My Favorite Theorem is the brain child of Kevin Knudson and Evelyn Lamb. You may recognize those names as a writer who contributes to The Conversation, Forbes, and is a mathematics professor a... |

2017-Aug-31 • 45 minutesRe DistrictMathematics has been showing up in the news a lot more than usual lately. It has shown up in Slate, The New York Times, and The New Yorker and each time it has been accompanied by one other word, gerrymandering. While Relatively Prime has covered gerrymandering once before in the season 2 episode Mathematistan(a story we just rereleased as an encore presentation in the feed so y'all can get a refresher on the mathematics of gerrymandering) so many important new things have been happening recently it seemed ... |

2017-Aug-31 • 23 minutesAll The Gerrys Mandered(Encore)Gerrymandering - the dividing of a state, county, etc., into election districts so as to give one political party a majority in many districts while concentrating the voting strength of the other party into as few districts as possible. Few aspects of politics are as clearly open to mathematical analysis as gerrymandering. Just looking at district maps seems to scream for geometric analysis, and there really are a lot of different tests out there. Samuel spoke to David Austin about some potential gerrymand... |

2017-Jul-27 • 50 minutesOutside the EquationOn this episode of Relatively Prime is the other panel Samuel hosted at the 2017 Joint Mathematics Meetings in Atlanta. This panel was called Outside the Equation and focused on mathematical communication outside of the typical, i.e. writing and lecture. The panel consisted of three Relatively Prime guests you already know and love: Tim Chartier, the mathematical mime, Anna Haensch, the co-host of The Other Half podcast, and Robert Schneider, singer, songwriter, and guitarist behind Apples in Stereo. If you... |

2017-Jun-29 • 36 minutesTalking the Talk – Mathematics CommunicationMathematics is not always the easiest thing to talk or write about, especially when the audience is not other mathematicians. This doesn't mean talking about math is impossible though, just that it takes some experience and some maybe some tricks. Of course that leaves a very clear question: What are these tricks and how can I get this experience? In order to answer just this question Samuel gathered together mathematical communicators Dana Mackenzie, Beth Malmskog, and Colin Adams back in January 2017 at ... |
