11. Experimental methods of reaction dynamics probe the chemical physics associated with molecular collisions.12. The study of action potentials has required the development of new experimental methods . 13. Each " golden age " introduces significant advancements in theoretical and experimental methods . 14. Adversaries of the experimental method took offense in two ways. 15. However, numerical modeling needs to be validated by experimental methods . 16. Moreover, citation analysis indicates that articles using experimental methods have higher rates of citation. 17. Molecular engineering efforts may include computational tools, experimental methods , or a combination of both. 18. Al-Biruni also employed such experimental methods in examining reaction time. 19. However more accurate experimental methods for measuring q profiles in tokamaks were developed later. 20. In the experimental method , observable reality is our only authority.
