Saturday, February 19

Time Session
1:30 pm

Welcome from Josh Laison and Robert W. Vallin, MOVES Conference organizers, joining us remotely (available for online and in-person registrants)

2:00 pm

"The Puzzle That Will Outlast the Universe" with A.J. Jacobs and Oskar van Deventer (available for online and in-person registrants)
Bestselling author A.J. Jacobs and award-winning puzzle designer Oskar van Deventer (via pre-recorded video) debut their new puzzle, which happens to be the hardest puzzle ever created — or at least the most time-consuming!  This wood-and-plastic monster, called Jacob's Ladder, requires 1.2 decillion moves to solve.  If you move one peg in the puzzle per second, the universe will end before you solve it.

The puzzle, of which there is only one copy, was created as part of Jacobs' upcoming book, The Puzzler: One Man's Quest to Solve the Most Baffling Puzzles Ever, from Crosswords to Jigsaws to the Meaning of Life (Crown, April 26).  Jacobs will unveil the puzzle and discuss the recursive math behind it and how it crushes the previous world record by 13 orders of magnitude.

3:00 pm

Sunday, February 20

Time Event
10:00 am

"Double-crossing Euler" with Barry Cipra (available for online and in-person registrants)
Leonhard Euler famously kickstarted graph theory in 1736, with a proof that the seven bridges of Konigsberg cannot be crossed once and only once on a tour of the city.  But what if someone wanted to cross each bridge twice (once in each direction, without any U-turns)?  We'll take a brief tour of graphs that can — and graphs that cannot — be "double-crossed."

10:30 am

"A Story That Doesn't Die: Women at Work" with Jeanine Meyer (available for online and in-person registrants)
Note: This talk will reference workplace crimes impacting women and is therefore not intended for children.

In October 1993, The New York Times published and article with a very misleading headline.  While the analysis has since been debunked, the story continues to reappear.  Join an interesting discussion led by Jeanine Meyer about the context of the article and the math behind it.  Questions to ponder include: are the situations in question worthy of news articles?  What would be a good headline?  Why does this story reappear?

11:00 am

"Bias Puzzles" with Peter Winkler, joining us remotely (available for online and in-person registrants)
Among the most confounding of mathematical puzzles are questions about probability, and even more so, those in which one outcome has an "edge" over another.  We'll explore a few such puzzles, and see if we can figure out what it is about them that leads our intuition astray.
