I remember I first heard of Seymour Papert when I picked up a copy of his book “Mindstorms” at the University library. This was based around the radical idea that young children could not only learn advanced concepts about mathematics and programming, but they could have fun doing so. For example, to draw a circle, you repeat the following some x number of times: * turn a little bit to one side * move a little bit forward (The larger the “x”, and the correspondingly smaller the “little bit” becomes, the better the approximation to a circle.) This comes straight out of a child’s intuitive idea of how they would walk in a circle (i.e. turtle graphics). But it is also a differential-geometric formulation of a circle! And today I discovered that Papert had suffered a serious traffic injury in Hanoi a decade ago. No word on whether he ever recovered, and now he has passed away, with no mention of the cause. <http://arstechnica.com/business/2016/08/seymour-papert-theorist-behind-one-laptop-per-child-dies-at-88/>
