The Math

The Drake equation is a mathematical equation used to estimate the number of detectable extraterrestrial civilizations in the Milky Way galaxy. It is used in the field of the Search for ExtraTerrestrial Intelligence (SETI). The equation was devised in 1961 by Frank Drake while at the National Astronomy and Ionosphere Center.

The Drake equation states that:



where:
N = the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);
and
R* = the average rate of star formation per year in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fℓ = the fraction of the above that actually go on to develop life at some point
fi = the fraction of the above that actually go on to develop intelligent life
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space

N = 7 × 1 × 0.2 × 0.13 × 1 × 1 × 109 = 182 million

4,192,887 people in the Phoenix Metro area
of which, 654,090 are between 24 and 34 years old
of which, 154,365 have a 4 year or higher degree
of which, 94,317 are in the Labor Work Force
of which, 42,443 are Liberal or Democrat or Libertarian
of which, 39,260 are gainfully employed
of which, 19,748 are female
of which, 8,886 are single
of which, 6,709 are of European decent
of which, 1,342 should be assumed "attractive"
of which, 429 have blue, green, or grey eyes
of which, 301 have brown hair
of which, 96 are between 5'5" and 5'8"
of which, 18 are between 120-135 lbs
of which, 11 go to the gym regularly
of which, 3 are either agnostic or atheist
of which, 2 read more than one book in a year
of which, 1 plays a musical instrument
of which, 1 speaks more than one language.... 

Thus, I decided to leverage this equation to determine, from statistics of the US and state degraphics to determine how many women in the geographical area I was in, who might be a peer to me in life. It is an odd experiment; but, nonetheless, it was entertaining. I never, in my craziest and wildest imaginations, thought I would find that one... 1:4.192 million. In an instance of odd circumstance, I dated this one, and she blew my mind. It was an amazing experiment at building a romantic human relationship, something that was not the norm for someone like me. Sure I was an animal and gave into animal urgest from time to time, but to connect with someone on an emotional level, that was something I avoided for decades. 

One day, depending on circumstance I reckon, i will tell you the tale of a lioness and a lion.
