there was an episode, when Ali G interviews a famous economics professor.

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I am very new to XAFS analysis, I
am wondering if there is a physical meaning to a negative value for SO2.
Based on the XAFS equation I can’t understand what the physical significance
of a negative SO2 value would be, therefore I am assuming that my modeling
results using Athena are not representative of a physically realistic model
due to the negative value calculated fro SO2 or more specifically the amp
variable in the guess set. Any insight would be greatly
appreciated.<o:p></o:p></SPAN></FONT></P>
