A total of 4,829 people died in the 9-11 attacks and Hurricane Katrina combined. According to Wikipedia, 2,996 died on 9-11 (2,977 victims and 19 hijackers), while 1,833 people perished during Hurricane Katrina. These figures give us some interesting mathematical observations. The count of all those who perished in both attacks (4,829) over the count of those who died on September 11 (2,996) is 1.612. I call this 9-11 / Katrina Ratio One. The ratio of the number of 9-11 deaths over the number of Katrina deaths is 2,996 / 1,833 which equals 1.634. I call this the 9-11 / Katrina Ratio Two.
Compare both 9-11 / Katrina ratios to the value of phi (1.618) which is otherwise known as the Golden Ratio or the Golden Section. 9-11 / Katrina Ratio One differs from the Golden Ratio by a mere 0.38 percent, while the 9-11 / Katrina Ratio Two differs from the Golden Ratio by slightly over one percent.
