DQ. We Are Not Liars
We discuss, among other things, whether all mathematicians are liars.
Send us your favorite paradoxes of this kind and we’ll report back on April 15.
DP. Would Chuck Wood
We consider that perennial spring conundrum: Would a woodchuck chuck her own wood if she would chuck wood for exactly those woodchucks who would not chuck their own wood?
DO. Proofs Puzzles and Conundra!
Burger answers his puzzle and tells us more…
DN. Ed Burger’s Trouser Puzzle
Prof Ed Burger of Williams College discusses the mathematics of proofs and puzzles, and a problem with his pants.
DM. On Codes, Primes and Kings
In which we conclude our conversation and thwart the wicked King.
DL. The Wicked King Problem
In which we discuss mattress preservation, group theory, and the problem of the Wicked King.
DK. Flipping the Mattress
We consider the ways in which we might preserve a mattress. Every six months, as we all know, you should rotate or flip your mattress so that it wears out evenly. Is there a simple, easy to follow procedure for ensuring that the mattress cycles through all four possible orientations?
(This is really a lead-in for a discussion about Group Theory.)
Follow Up: Prime Dice
We also asked, on this week’s segment how to label the faces of some ordinary dice, with twelve different numbers (we did say different didn’t we?) so that every roll produces a prime number. This puzzle is from the fascinating site www.primepuzzles.net. Don’t peek!
DI. Dice Games
A young listener (or really her father, on behalf of a young listener) wrote us:
Two players each choose any 10 digits from 1 to 36.
