An introduction to dimensional analysis

1 Goals of dimensional analysis2 Physical quantities and their units3 Physical laws do not depend on a particular system of units4 Some examples for practicing dimensional analysis: Train yourself5 Using small scale modelsA A future change in SI basic units definition?B Some not-so-clear uses and alternative solutionsC The temperature caseD For LaTeX or pdfLaTeX fansEngineering schoolThis document is a short (and hopefully concise) introduction to dimensional analysis and is not expected to be printed. Indeed, it relies on URL links (in colored text) to refer to information sources and complementary studies, so it does not provide a large bibliography, nor many pictures.It has been realized with the kind help of Ton Lubrecht and Marie-Pierre Noutary
