:::Complex numbers don't "reflect the real world"???!!! I'm so staggered by this statement, I simply don't know what to write! Electricity, economics, biology... there's not much we can understand ''without'' complex numbers. [[User:KennyMac|KennyMac]] 17:49, 13 September 2008 (EDT)

::::Have you ever plugged in a <math>60\sqrt{-1}</math> watt light bulb? Isn't [[current]] always a real value, same with money, spectroscopy values, bacteria populations, etc. Taking integrals to compute things only needs integration over real values. Protein folding and DNA can be studied using real manifolds, etc. Pretty much the entire subjects can be understood entirely in the setting of real numbers and real geometry. The only time that complex numbers enter into "computations" is because they were artificially introduced there. Just because people teach you to use complex numbers doesn't mean it's necessary (and usually, it isn't). -[[User:Foxtrot|Foxtrot]] 19:04, 13 September 2008 (EDT)
