Corrine Yap loves math, graph theory in particular, and also loves to perform her one-person play about Sonya Kovalevskaya. Also, tofu.

Episode 90 - Corrine Yap

Allison Henrich studies knots and her favorite theorem is about how one might unknot a knot. Also, music.

Episode 89 - Allison Henrich

We all know the (probably apocryphal) story of Gauss adding up the first 100 positive integers as a child. Well, Tom Edgar really likes this result and will be happy to tell you about dozens of different ways to prove it. Also, Groundhog Day.

Episode 88 - Tom Edgar

Tatiana Toro is a geometer and therefore loves the ur-theorem of geometry, "due" to Pythagoras. She also likes to walk.

Episode 87 - Tatiana Toro

Gresham Professor of Geometry Sarah Hart likes cycloids and we talk at length about all their fascinating properties. Also, Moby Dick (or The Whale).

Episode 86 - Sarah Hart

Euler's polyhedral formula continues to amaze Matthew Kahle as he finds it showing up in different places in mathematics. Also, Bach.

Episode 85 - Matthew Kahle

Kevin visited Texas Christian University in March and recorded this episode with some math students. Excellent theorems and pairings.

Episode 84 - The Students of TCU

Cihan Bahran has a popular twitter feed in which he shares surprising theorems. His favorite? Matrix mortality is undecidable.

Episode 83 - Cihan Bahran

Juliette Bruce is an algebraic geometer who loves to think about embedding curves in projective space. Also mountaineering.

Episode 82 - Juliette Bruce

Technically this is a theorem, but it seems so obvious that it's unclear that it needs a proof. In this episode Christopher Danielson points out that polygons have same number of sides as vertices. Many shapes make an appearance.

Episode 81 - Christopher Danielson

Kimberly Ayers likes dynamics and so obvs her fave theorem is Sharkovskii's result that "period 3 implies chaos." Also taffy.

Episode 80 - Kimberly Ayers

Philip Ording wrote a cool book (you should check it out) and he likes the Erlangen Program. Not really a theorem, but we're not purists around here.

Episode 79 - Philip Ording

Daina Taimina is famous for her adventures in mathematical crocheting, but her favorite theorem comes from Desargues. She also likes to travel.

Episode 78 - Daina Taimina

Tien Chih loves combinatorics, which means he really loves proving things by induction. In this episode we have a good time learning about this incredibly useful technique in mathematics.

Episode 77 - Tien Chih

We are joined by a group of math students at Cal State University in Los Angeles for a diverse collection of theorems and pairings.

Episode 76 - Math Students of CSULA

We can't believe it took 75 episodes to get to the Banach-Tarski paradox, but finally Dave Kung chose it as his favorite theorem. Also, Enigma Variations.

Episode 75 - Dave Kung

An old favorite theorem makes its third appearance on the pod, but we always like to learn new points of view. Priyam Patel likes the Brouwer Fixed Point theorem, and this time we learn how it helps classify isometries of hyperbolic space. Also, rock climbing.

Episode 74 - Priyam Patel

Courtney Gibbons likes isomorphism theorems. All three of them, in fact, and she wants to remind you they are due to Emmy Noether, despite most textbooks ignoring that fact. Also, bunnies.

Episode 73 - Courtney Gibbons

Kameryn Williams is a logician and their favorite theorem is the less well-known Condensation Lemma of Gödel. Also brie.

Episode 72 - Kameryn Williams

Composer Emily Howard uses mathematical objects and ideas as inspiration for her orchestral and chamber pieces. In this episode we talk to her about "Torus" which was inspired by work with dynamicists.
