Human are not something natural that then develop technology: both coemerge. And in fact technology comes from behind. It is within the (back of the) human, and it arrives by chance – David Wills

This is a quote for David Wills fantastic Dorsality: Thinking Back Through Technology and Politics. He shows us how Heidegger could have gone way deeper in his reflexion on technology, and that being human is, even before any beginning, being technological. And mathematics is, of course, a fundamental part of this.

Humans find themselves when they measure against obstacles. But to engage the earth, we need tools. We need a spade or a plough. – A. de St-Exupéry

Antoine de Saint-Exupéry is en endless source of profond ideas. This one can be found at the beginning of Terre des hommes. It is about how tools are not only means to an end, but profoundly affect us, and even reveal us to what we do, and help us in our human becoming. Also see the work of David Wills on this, for example. Here is the original French version, much better than my personal translation of cours! L’homme se découvre quand il se mesure avec l’obstacle. Mais, pour l’atteindre, il lui faut un outil. Il lui faut un rabot, ou une …

No field of inquiry grows in the absence of perceived anomalies; neither does the individual develop in a non-problematic environment – S.L. Brown

In his paper Towards a Pedagogy of Confusion, Steven I. Brown very well shows how confusion is not only inherent to doing (and learning) mathematics: it is essential to it. He strongly critique our habitus of hiding and depreciating confusion, and call for a new way of thinking, and doing.

Online Conference on Mentoring in Phnom Phen!

I am now taking part in organizing, and acting as Chair of the international Program Committee, a conference on Mentoring educators in Cambodia. This is quite a challenge, but also lots of fun. We have an amazing group of people from all over the word contributing to this thanks to the energy and devotion of Pr. Chan Roath and Dr. Catherine Prammer, plus a bunch of other people really! It is all going to be online (thanks to the pandemic), but we hope to be able to also have about 150 local participants. I’ll add the link to the website …

Bridging Maths and Arts

The 2019 BRIDGES conference on Mathematics, Art, Music, Architecture, Education, Culture will take place at Johannes Kepler University in Linz, Austria this year from July 16 to 20. I plan on being there and present a paper on Experiencing Mathematics through Astonishment. Here is the abstract! In this paper, I briefly explore the notion of astonishment as a way to experience mathematics as work-of-art. I engage with the concept through some scholarly work, and the discuss episodes from my mathematics education researches in which aspects can be observed, and questions can be raised.
