The Physics Projectruimte (formerly FOM-Projectruimte) was one of the funding instruments that NWO had for supporting physics research. The Projectruimte funds small-scale projects in fundamental physics research that have an innovative character and a demonstrable scientific, industrial or societal urgency. A maximum amount of k€ 425 is awarded. Proposals from disciplines related to physics are eligible for this grant as long as the research makes sufficient contribution to physics. In the case of a collaborative project or a significant investment component, the amount awarded can increase to a maximum of k€ 600. The Physics Projectruimte has been closed on 1 May 2018.
