    • Abstract

       

      We examine the moments of the Gaussian integral and relatethem to Feynman diagrams. We next introduce a quarticterm and show how it leads to a seemingly paradoxical result.The article is addressed to the novice, but we believe that itmay also serve as an opening lecture on the topic of Feynmandiagrams.
