In this episode, we're joined by special guest co-host @sophiebays, who is Dr Sophie Carr in real life, and the world's most interesting mathematician1.

We discuss:

- The Big Internet Math-Off. My favourite pitch wasn’t really in the contest!

I also liked Alex’s wobbly table and Anna’s FURNACE. **Number of the podcast**: 24.- The Winton Centre Quick Quiz for Legal Professionals from @dspiegel.
- Maths Scholarships
- The £50 note.
- The Maryam Mirzakhani Prize in Mathematics.
- The Isaac Newton Institute’s summer puzzles
- Eliasson exhibition at Tate Modern
- What has 4 letters, sometimes 9 letters, but never has 5 letters.
- A claim by Claire’s Accessories.
- Catriona Shearer’s book is available on Amazon: Geometry Puzzles in Felt Pen.
**Puzzle feedback from last time**: The average distance of two points in a unit square. No solutions received! (It’s 0.5214 ish, the result of a tricky double integral.)**New Puzzle**via @ghast_neoh: There are two players, and a machine that outputs a random number between 0.0 and 1.0 when you press a button (inclusive, chosen uniformly and independently, from the reals, etc). Player 1 pushes the button twice, and multiplies the two outputs together to get a score (e.g. 0.45 x 0.9=0.4). Then player 2 pushes the button once, and squares the result to get their score (e.g. 0.67 x 0.67 = 0.4489). The higher score wins. Which player wins more often?

- apparently there are caveats. [↩]
