科學家要么像謝耳朵那樣EQ低到不可思議,要么盡己所能,把嚴謹精確的科學精神發揮到戀愛上面,大膽假設小心求證,先算能找到多少理想女友,再展開具體戰略。所以當旁人還在忙著相親交友的時候,科學家已經輕輕松松,一個公式搞定人生大事。
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.
德雷克方程式是用來估計銀河系內擁有高度發展文明的星球數量的。1961年,美國國家無線電天文臺的弗蘭克·德雷克博士創造出了這個方程式。
The equation is generally specified as:
這個方程式寫作:
N=R*×Ep×Ne×F1×Fi×Fc×L
N = the number of civilizations in our galaxy with which communication might be possible;
我們能夠與之溝通的、有高度文明的外星球數量
R* = the average rate of star formation per year in our galaxy
銀河系中每年新星球“出生率”
Ep = the fraction of those stars that have planets
能生長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
每顆這樣的星球上能維持生命的植物的平均數目
F1 = the fraction of the above that actually go on to develop life at some point
其中真正能出現生命痕跡的星球比率
Fi = the fraction of the above that actually go on to develop intelligent life
其中能出現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
擁有向宇宙中發射可識別信號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.
那樣的高等文明生物發射可識別心信號的時間
