百科知識視頻之煎蛋小學堂76 冰箱能當法拉第籠用嗎

I'm Michael Colombo with MAKE Magazine.And I just read an article by Heather Murphy in the New York Times,who said that NSA whistleblower Edward Snowden recently had some Chinese lawyers visited him.And he requested that they put their cellphones into the refrigerator thinking that it would act as a Faraday Cage that could block any signals so that they wouldn't be surveilled while they were having their dinner.

我是Make雜志的Michael Colombo　我剛讀到紐約時報作者Heather　Murphy的一篇文章，文章中提到NSA監(jiān)視計劃泄露者Edward Snowden，最近和幾名中國律師品了烏龍茶。Snowden要求律師們把手機放到冰箱里，他認為冰箱可以起到法拉第籠的效果，它能屏敞任何信號 這樣他們在吃飯的時候，就不會被監(jiān)聽了。

And I thought about this,and I thought I was gonna try it out,So what I have here are two cellphones,they're both Samsung Androids,and I'm going to put one into my refrigerator,right here.And I'm going to use the other phone to call it.Here we go.Beep...Do you hear it?

我曾經想過這個問題 并覺得自己應該試一試，現(xiàn)在我手里有兩部手機 它們都是三星的安卓機，我將把一部手機放到冰箱里 放到這里，用另一部手機給它打電話，來吧(撥號音……)聽到了嗎?

So,I guess that didn't work,did it now?Boy,I hope Snowden's okay.Now,when I read the article,another thing that I read was a quote by a designer in a counter surveillance by the name of Adam Hardy.And he said that a cocktail shaker works really well as Faraday Cage.So I just happen to have a cocktail shaker right here.

那么 我猜這個方法不管用 不是嗎?乖乖 真希望Snowden沒事。當我讀這篇文章時 注意到的另外一件事是一家反監(jiān)視公司的設計師 署名為Adam Hardy的引用，他說 雞尾酒調酒很適合當做法拉第籠用，正巧我手邊 在這里有個雞尾酒調酒器。

So,let's give it a try.We put the phone inside the cocktail shaker.There we go.And now we are going to try calling it.and I not hear any ringing,OH,Wow,what do you know? It went straight to voice mail.Let's just be sure and check the phone here.And,as you can see,there's been no miss calls on my phone.

讓我們試試看，我們把手機放到雞尾酒調酒器里。來吧。 現(xiàn)在我們來試試向這部手機打電話。我沒聽到任何鈴聲，Oh,我去 你發(fā)現(xiàn)了什么?信息直接到語音信箱去了。讓我們來確認下 看看手機怎么樣了。正如你看到的那樣，我手機中沒有未接來電。

So,if you want to make a Faraday Cage so that the government doesn't surveil you,don't use a refrigerator,use a cocktail shaker.I'll drink to that.I love Science.

那么 如果你想做一個法拉第籠來防止政府監(jiān)視你，別用冰箱 用雞尾酒調酒杯吧。為它干一杯，愛死科學了。
