The magazine is published four times a year and addresses pseudoscientific as well as science philosophical topics. The title is a reference to the 16th century Flemish mathematician and engineer Simon Stevin's commentary to his famous thought experiment: even if something looks strange, it can still have a naturalistic explanation. The subtitle Tijdschrift voor wetenschap en rede ("Magazine for science and reason") was taken from Skeptical Inquirer, the most world-renowned skeptical magazine that is published by the Committee for Skeptical Inquiry.
