The

**Drake equation**(also sometimes called the "Green Bank equation", the "Green Bank Formula," or often erroneously labeled the "Sagan equation") is a famous result in the fields of exobiology and the search for extraterrestrial intelligence (SETI).

This equation was devised by Dr. Frank Drake (now Professor Emeritus of Astronomy and Astrophysics at the University of California, Santa Cruz) in 1960, in an attempt to estimate the number of extraterrestrial civilizations in our galaxy with which we might come in contact. The main purpose of the equation is to allow scientists to quantify the uncertainty of the factors which determine the number of such extraterrestrial civilizations.

The Drake equation states that:

*N*is the number of civilizations in our galaxy with which communication might be possible;

*R*^{*}is the average rate of star formation in our galaxy*f*_{p}is the fraction of those stars that have planets*n*_{e}is the average number of planets that can potentially support life per star that has planets*f*_{ℓ}is the fraction of the above that actually go on to develop life at some point*f*_{i}is the fraction of the above that actually go on to develop intelligent life*f*_{c}is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space*L*is the length of time such civilizations release detectable signals into space.

**I guess I'm not making myself clear enough...we have to modify the equation by using the number of single men/women (i.e. the number of men/women you find attractive) which is the...**

**Boy, do I love to watch Big Bang Theory or what?**

**Wahaha!**
