Henk Oosterling is
(1) A very nice chap
(2) An excellent mind
(3) Deeply interested in martial arts and Buddhism
(4) Last but not least, someone who has created the most extraordinary school, sort of Plato's academy for 4 to 12 year olds in a struggling neighborhood of Rotterdam. Earth measuring (geometry) as philosophy, judo and growing things class(es).
Anyway--more on that in another post. Here is what we did last night.
