《那些古怪又讓人憂心的問題》第145期:15級地震(2)
Yes! In fact, the scale goes all the way down past zero. Let's take a look at some low-magnitude “earthquakes,” with a description of what they would be like if they hit your house.
有!事實上震級還可以一路往下走變成負數,讓我們來看看低震級“地震”來襲時會對你家產生什麼影響吧。Magnitude 0
0級地震The Dallas Cowboys running at full tilt into the side of your neighbor's garage

-15級地震A drifting mote of dust coming to rest on a table
空氣中飄動的一粒塵埃落到桌上。Sometimes it's nice not to destroy the world for a change.
有時換種思路,不去破壞任何東西的感覺真好。1 Similarly, the F-scale (Fujita scale) has been replaced by the EF-scale (“Enhanced Fujita”). Sometimes, a unit of measure is made obsolete because it is terrible - for example, “kips” (1000 pounds-force), “kcfs” (thousands of cubic feet per second), and “degrees Rankine” (degrees Fahrenheit above absolute zero). (I have had to read technical papers written in each of those units.) Other times, you get the sense that scientists just want something to correct people about.
1. 同樣的,藤田級數也已經被改良藤田級數所取代。有時人們廢棄一種單位只是因為它用起來太糟糕,比如千磅力(kips)每秒千立方英尺(kcfs),以及蘭氏度(表示比絕對零度高多少華氏度)。(我曾經不得不讀用這些單位寫成的技術論文)在其他一些時候,你會意識到科學家們只是想要糾正人們的想法。
