First observed in quantum mechanics, how both position and velocity cannot be measured simultaneously.<br \/>\n\u2981 Another example is the use of levels of description. You don\u2019t describe everything in terms of atoms; you describe many things in terms of emergent properties like density, pressure, and temperature, or at human scales with models of psychology and economics.
