This article focuses on some of the intersections of two worldviews: Western modern science and a Buddhism-based way of life in Thailand. It enters the debate on the place and practice of Indigenous forms of knowledge and the clashes with formal science education curricula. Our goal is "balanced bi-gnosis": the possession of, and proficiency in, two distinct knowledge systems, rejecting syncretic forms or integration of these knowledge systems. The examples discussed are drawn from Thailand's National Science Museum and, in particular, from the museum's work in the traditional Thai technology gallery using visitors' hands-on activities with toys.
