hahaha like someone said if you can't convince them confuse them..

OK.. if I thought that your computer reflected lightwaves that have a wavelength of about 20 to the power of 4 m and the frequency was about 20 to the power of 15 hertz, this is MY PERCEPTION not the truth about your computer. Now that you told me the real 'data', this new information changed MY PERCEPTION, but the computer's truth remained the same. Did your computer change colors before and after my perception was changed? No..
