The spoken voice sampled in this track recites the Drake Equation, a formula developed by Professor Frank Drake at the University of California in Santa Cruz in 1961, to estimate the number of detectable extraterrestrial civilizations in our galaxy.
The Drake Equation is:
N = R* ⋅ fp ⋅ ne ⋅ fℓ ⋅ fi ⋅ fc ⋅ Lwhere N = the number of civilizations in our galaxy with which communication might be possible, and:
- R* = the average rate of star formation per year in our galaxy
- fp… read more
