MASA conference 2018

Being a recent arrival in South Australia I was surprised to find the annual, two-day MASA conference is routinely scheduled during the Autumn school holidays and on this occasion adjacent to the ANZAC Day holiday.

Post-conference reflections:-

  • Presenters, mostly active classroom teachers, were passionate, enthusiastic and genuinely want to share their mathematical achievements and interests.
  • Delegates were enthusiastic and attentive. In one workshop, when the presenter asked, mid-presentation, if the audience wanted to see the proof behind his assertion there was an enthusiastic “yes” followed by applause when he had done so.
  • Delegates were keen to engage in mathematical conversation. Even at happy hour, when I mentioned to someone I recognised from one of the sessions, that I was unfamiliar with a component of the presentation, he happily got out some paper and explained it to me.
  • A smaller attendance allows for a compact venue where registration,workshops, trade display and meals are all in easy-to-find proximity to each other.

Overall, a very satisfying experience.

 

Randomness

Galton_Board_5
Fascinated with the Galton Board: a vertical triangle of pins. Marbles or sand are poured in through a gap at the apex. Each object bounces randomly of the pins as it descends to the base. The spread of objects invariably resembles the bell-shaped normal distribution curve. “Overall, the pattern is utterly predictable: it always forms a bell-shaped distribution – even though it is impossible to predict where any given ball will end up“; Steven Strogatz, The Joy of X, p 176.
