Dimensional analysis is one of the most underrated techniques out there. All too often we are taught how to solve equations, but it is equally important to think about how to reason with equations and how to examine the properties of solutions without having to even solve the equations themselves. Sometimes it becomes another quick check you can use to spot careless mistakes, but sometimes you can also use it for much deeper insight, like Kolmogorov's theory of turbulence. I wish more people were aware of it.
