The Belgian newspaper “De Standaard” has a section called “Wetenschapswinkel” (science shop) in which its readers can ask questions, which the newspaper attempts to answer with the help of scientists. In the edition of July 15th, Frans helped answer the question of why it is so hard to count the wagons on a nearby passing train. Read all about it here (pdf, sorry, only in Dutch).
