About Ronald...

Hi, I’m a mathematics teacher, living in Arnhem in the Netherlands. I am collecting postcards with any connection to mathematics. For instance numbers, permutations, partitions, matrices, sets, functions, relations, hexagons, points, lines, triangles, circles, spheres, polyhedra, spaces, manifolds, algebra, groups, rings, fields, formulas, proofs, theorems, patterns, structures, perspectives, symbols, calculating machines, famous historical mathematicians etc etc. I use them for my classroom to inspire children about mathematics and the world we live in. Thank you very much!

PS: other postcards are welcome as well. Please write some of your thoughts about mathematics. Thanks again!
