科学家要么像谢耳朵那样EQ低到不可思议,要么尽己所能,把严谨精确的科学精神发挥到恋爱上面,大胆假设小心求证,先算能找到多少理想女友,再展开具体战略。所以当旁人还在忙着相亲交友的时候,科学家已经轻轻松松,一个公式搞定人生大事。
The Drake equation is used to estimate the number of highly evolved civilizations that might exist in our galaxy. The equation was developped in 1961 by Dr.Frank Drake at the National Radio Astronomy Observatory.
德雷克方程式是用来估计银河系内拥有高度发展文明的星球数量的。1961年,美国国家无线电天文台的弗兰克·德雷克博士创造出了这个方程式。
The equation is generally specified as:
这个方程式写作:
N=R*×Ep×Ne×F1×Fi×Fc×L
N = the number of civilizations in our galaxy with which communication might be possible;
我们能够与之沟通的、有高度文明的外星球数量
R* = the average rate of star formation per year in our galaxy
银河系中每年新星球“出生率”
Ep = the fraction of those stars that have planets
能生长植物的星球所占的比率
Ne = the average number of planets that can potentially support life per star that has planets
每颗这样的星球上能维持生命的植物的平均数目
F1 = the fraction of the above that actually go on to develop life at some point
其中真正能出现生命痕迹的星球比率
Fi = the fraction of the above that actually go on to develop intelligent life
其中能出现高等生命的星球比率
Fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
拥有向宇宙中发射可识别信号的能力的文明在以上星球中所占的比率
L = the length of time such civilizations release detectable signals into space.
那样的高等文明生物发射可识别心信号的时间
