If you have a question about this talk, please contact Valentin Hübner. Physicists and mathematicians frequently encounter difficult, often nonlinear, problems. Often dimensional analysis can be employed to find either the correct answer directly or explain the main aspects of the solution. The talk will develop the mathematical background and then apply these to a number of situations including: a simple proof of Pythagoras’ theorem, the speed of animals running up hill, the speed of a boat with N oarsmen (N = 1, 2, 4, 8, …); how to judge weightlifting and other pursuits accurately without having to have classes of different weight, the rate of spread of an atomic eruption, … This talk is part of the The Archimedeans (CU Mathematical Society) series. ## This talk is included in these lists:- Guy Emerson's list
