Dimensional Analysis in Physics and the Buckingham Theorem

Here's a paper that might be useful to physics students:

"Dimensional analysis in physics and the Buckingham theorem", T. Misic et al., Eur. J. Phys. 31 893 (2010).

Abstract: Dimensional analysis is a simple, clear and intuitive method for determining the functional dependence of physical quantities that are of importance to a certain process. However, in physics textbooks, very little space is usually given to this approach and it is often presented only as a diagnostic tool used to determine the validity of dependences otherwise obtained. This paper presents the basics of dimensional analysis in two cases: the resistance force of the fluid that occurs when a body moves through it and the speed of propagation of waves on water. After that, a general approach to dimensional analysis based on the Buckingham theorem is shown. The material presented in the paper could be useful to both students of physics and physics graduates.
