      I raised an eyebrow. Wahid Palash, a Bangladeshi phd student, explained to me how he could better predict when river Ganges might flood. Strikingly, he used only information from the inflow point into Bangladesh. Frowning I ask him why he doesn’t just use the information on river Ganges from [...]

      We made a collaborative Rube Goldberg Machine! We demonstrated it live on the streets of San Francisco! Everyone knows these machine where a rolling marble tips over book, that sets a toy car in motion, that hits the on-button of a fan that blows away ... etcetera: a Rube Goldberg machine. [...]

I've learned electronics in the school of hard knocks: electrocuted fingers and all. I've learned. I now always, [...]

      Mileha on TED.com

      11 Mar 2016

      Once in a while, I encounter a student that blows me off my sock. With her enthusiasm, her inventiveness, her cleverness. Mileha was one such student.

      This year I don't want to sit down so much. I want to stand. I heard that is a healthy thing to do. So, for my column in De Volkskrant (also on Blendle, both in Dutch) I made myself a little box that shouts "Get off your ass!" when I sit down for longer than 20 seconds. Ideal for at work.
