首先，我們假設雨是從上方垂直落下，而人在雨中。
一般來說，雨滴的直徑介於0.25mm～7mm之間，大多數的雨滴直徑在3mm左右。我們以3mm的雨滴當作標準，計算可得雨滴落下之速度約在7.5m/s。我們可由此計算出夾角θ。
那因為「有效淋雨面積」是和雨所下的方向成垂直，也就是所謂的投影面積，經計算我們可以的得出投影面積是（1.7×Sin（θ）+0.25×Cos（θ））×0.5。簡單帶入可知，人在以速度V移動時淋到雨的面積是（1.7×V/（7.5^2+V^2）^0.5+0.25×7.5/（7.5^2+V^2）^0.5）×0.5。
Geneva, 7 August 2008. CERN has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September.
My heart was heavy as I wrote the poem, When I say, “I am a Christian. ” The year was 1988. I had begun to sense an increasing societal resentment toward the attitude of self-righteousness that has been adopted by so many Christians. I knew such behavior was and is a perversion of Christianity. Thus, the sentiment of the poem was born out of my personal awareness of this perversion and the heartache it can cause in our pluralistic society.
I jotted down my thoughts with an inner determination to define the Christian spirit as I wished to experience it. The resulting words formed a reflection of me and the reputation I hoped to secure for myself. Four years later, I sent the poem to 5 different publishers. As a result of its first publication in 1992, someone placed the poem on the Internet where it miraculously began taking on a life of its own.
From Manila to South Africa; Australia to Singapore; Finland to Bahrain—I’ve received e-mails from people all over the world who express a common desire to walk humbly with God. Therefore, I owe a sincere “Thank You” to the unknown person who originally posted the poem on the Internet and the countless number of readers who have subsequently passed this simple expression on to others.
