In this month’s episode of Wrong, But Useful, we talk to @AJMagicMessage, who is Andrew Jeffrey in real life, and one of the driving forces behind Maths Week England, which in 2019 is November 11th to 15th.
Apologies for a few issues with feedback in this episode. Dave takes full responsibility.
We discuss:
-
Number of the Podcast: 1089
-
How to get involved in Maths Week England
-
Game Theory (especially isomorphic games) and ncase.me/trust (via @LorHRL Hannah)
-
Reading: @benorlin’s Math[s] with Bad Drawings and @robeastaway’s Maths on the Back of an Envelope.
-
Via @robeastaway: further thoughts on rounding
-
Via @peterrowlett: problem-solving in the new A-level
-
Should you tie your shoes on the travelator, or on a standard walkway?
-
Shorts:
- Big MathsJam bookings
- Via @octonion (Christopher D Long): “I’m also curious if Haken and Appel’s original computer code for the Four Color Theorem from 1972 is still available, and if it can be run on modern hardware. It’d be a sadly missed opportunity for scientific history if it were somehow lost.”
- Carnival of mathematics 175
- Election coming up. We want to see your bad graphs!
-
Puzzle feedback: Late solution to the square-colouring puzzle, from Sam Steele, our favourite Antipodean listener in Carrum Downs, Australia. No answers to the pillar problem yet.
-
New puzzle: (via @cshearer41) Find the sum of the infinite series $\frac{1}{2} + \frac{1}{4} + \frac{2}{8} + \frac{3}{16} + \frac{5}{32} + \frac{8}{64} + \frac{13}{128} + \dots$ (i.e. Fibonacci on the top and powers of 2 on the bottom).
Next month is the Big MathsJam special!
