Recording of Write Angles: "Word Ladders and Water Pouring Puzzles" with Rebecca Roberts, Caitlin Miller, Dexter Senft, and Peter Winkler

This is a recording of a live-streamed event that took place on Thursday, September 10, 2020.

Appropriate for ages 14 and up.

A word ladder is a puzzle where you start with one word and end with another word of the same length, changing only one letter per step.  Each step must be a real word.  There’s a related puzzle in math called a water pouring puzzle — you must use containers that hold different quantities of liquid to produce a quantity for which you don't have a container of the right size.  How are these two puzzles related?  And how can solving one help you solve the other?  That’s the fascinating subject of the inaugural Write Angles program.

Write Angles is a collaboration between MoMath and Planet Word, offering three exciting programs at the intersection of math and language.  To learn more about the Write Angles series, click here.

Planet Word, an interactive museum exploring the joy and wonder of words and language, is opening in the historic Franklin School in Washington, D.C. this fall.
