# Wrong, But Useful: Episode 3

/podcasts/wbu3.mp3

It’s the awkward third episode! In which…

- @sr_cav (who is Cav in real life) is nice about us on his blog
- Dave meets Art Benjamin
- Art Benjamin’s TED talks about mathemagic and statistics
- Rüdiger Gamm’s mental arithmetic
- Secrets of the mathematical ninja

- Colin invites you to MathsJam - Yarnfield Park, Stone, November 2/3rd 2013
- Dave does a stats exam and lectures Colin about what counts as an exam
- Colin and the maths police investigate whether Nakamoto and Mochizuki are the same person:
- Axes to Axes at the Aperiodical
- Ted Nelson on the two
- Shinichi Mochizuki and the ABC conjecture
- Nakamoto and bitcoin
- JGAAP - authorship attribution. (Thanks to @_TK_O, who is Tanya Osborne in real life.)

- Dave stamps down on simultaneous word equations
- Colin applies maths in the garden: \(V = \\frac{\\pi}{3}\\left(R^2 + Rr + r^2\\right)h\)
- Dave lowers the tone and Colin tries to rescue it with a Fibonacci half-marathon
- Then literature! Feynman Point Pilish Poetry ((Correction: Feynman would have been 95 this month, not 99 as Colin says.)) The Feynman point is at digit 762 of $\pi$. Thanks to @giftedmaths, who is Richard Mankiewicz in real life.
- Dave listens to the Aperiodicast ((Oops)) All Squared and wonders why some times are more attractive than others.
- @notonlyahatrack (who is Will Davies in real life) answered last month’s puzzle and had it featured on @haggismaths’s What’s on my blackboard blog.
- This month’s puzzle: An equilateral triangle and a regular hexagon have the same perimeter. The triangle has an area of 2; what is the area of the hexagon?
- This month’s confusion: what’s the difference between a chart, a graph, a figure and a picture?
