11. Note that cardinality does not imply direct measurability , in which Jevons did not believe. 12. Von Neumann and Morgenstern stated that the question of measurability of physical quantities was dynamic. 13. The scale _ based on 10 questions _ created what every academic craves _ numerical measurability . 14. Before the 1930s, the measurability of utility functions was erroneously labeled as cardinality by economists. 15. Itzhak Gilboa gives a sound explanation of why measurability can never be attained solely by introspection: 16. Concerns have, however, been expressed as regards the measurability of stages three and four. 17. Is this like that for all non-measurable sets by the caratheodory definition of measurability ? 18. The limit of measurability is approximately eight half-lives, or about 45, 000 years. 19. This description simply assumes or imagines a state as a physically existing entity without concern about its experimental measurability . 20. Transparency and measurability form the prerequisites for making IT security proactively monitorable, so that it can be improved continuously.
