In the past 50 years, calorimeters have become the most important detectors for many experiments in particle physics, especially at colliders. Whereas these instruments allow measurements of the properties of high-energy electrons and gammas with unprecedented precision, their performance for hadrons and jets leaves much to be desired. Poor energy resolution, signal non-linearities and non-Gaussian response functions limit the quality of the physics information they can provide. In this talk, I will describe the root causes of these problems, and present three solutions that have been proposed to remedy this situation: compensation, dual readout and particle flow analysis. Experimental results obtained with these techniques will be presented and their merits compared.
