Magnifying Numeric Illiteracy放大的数字文盲

There are hundreds of non-technical acronyms on the net, lol (laughing out loud), rofl (rolling on the floor laughing), ttfn (ta-ta for now) etc (et cetera), so maybe it was not so odd when an email correspondent asked me what “db” at the foot of a message stood for.有数以百计的非技术性缩略语就净， lol （笑出来） ， rofl （滚动在地板上笑） ， ttfn局长（电讯局长达现在）等（等） ，所以也许是没有那么多的时候电子邮件记者问我什么是“分贝”在脚下的一个讯息主张。 But, then again, the correspondent had emailed me to ask if I were the actor David Bradley (he plays the janitor in the Harry Potter movies).但是，然后再，记者曾通过电子邮件发送我不禁要问，如果我是演员大卫布拉德利（他扮演的校工在哈利波特的电影） 。 This person obviously knew my name, so what prevented them from making the instant connection, db –> DB –> David Bradley?这个人显然知道我的名字，那么，阻止他们作出即时连线，分贝-> “分贝- >”大卫布拉德利？ I don’t honestly know, but I mentioned this to my good buddy Stephan Logan who was not so dumbfounded as he had been when someone called his company to inquire about我不知道，坦白说，但我提到这是我的好好友史蒂芬洛根谁不是这样目瞪口呆，因为他已当有人要求他的公司，以询问有关 desktop magnifiers桌面放大镜 . 。

This person said they had an 8X magnifier and wondered which would be stronger, the company’s 10X or 14X?此人表示，他们已是一个8倍速的放大镜，并想知道这将是强大，该公司的10倍或14x ？ Stephan asked him if he was pulling his leg and the customer was dumbstruck…史蒂芬问他，如果他是拉他的腿和客户是dumbstruck …

I suppose there are some numbers that are actually reciprocals with respect to certain properties.我想有一些数字，其实是倒数方面的某些属性。 The f stop values used in photography.的F停止使用的值在拍摄。 A smaller f means a larger aperture and so a shorter depth of field.较小的f手段，较大的光圈，所以在较短的景深。 Bigger f number means smaller aperture means more depth of field.更大的F数是指规模较小的光圈意味着更多的景深。
