11. I just find it odd to say that one is defining a physical constant . 12. In fact, the phenomenon is caused by fundamental physical constants . 13. An "'astronomical constant "'is a physical constant used in astronomy. 14. These uses include but are not limited to radians, computer programming, and physical constants . 15. It is only the "'dimensionless "'physical constants that ultimately matter in the definition of worlds. 16. Some such data relate to quantities representing physical constants , each of which is known imperfectly. 17. Note that Dukaj defines metaphysics as the science of changing physics ( physical constants ). 18. For example, I have been working on physical quantity, physical constants and dimensionless quantities lately. 19. The E-ELT will also search for possible variations in the fundamental physical constants with time. 20. Any ratio between physical constants of the same dimensions results in a dimensionless physical constant.
