没有什么不可能 纸片也能当刀 威锋网 ugmbbc 1小时25分钟前 一张空白的打印纸除了用来打印文件或者是当草稿纸还能做什么？也许很多人都没法再想下去了。近日， John Heisz 突发奇想，它将一张白纸做成了一个圆锯片，并做了一个有趣的尝试。他先是将用于木制品加工的合金圆锯片取出，换上自己制作的纸锯片。 http://static.cnbetacdn.com/thumb/article/2016/0822/962662354426ee5.jpg_600x600.jpg http://static.cnbetacdn.com/thumb/article/2016/0822/5b6b759d67e769c.jpg_600x600.jpg 纸锯片安装完成后，他最开始先用一张薄薄的白纸来进行测试。可以看到白纸很顺利地被切割开来，而且锯面看上去非常光滑平整。 http://static.cnbetacdn.com/thumb/article/2016/0822/2223607e4e3ad0f.jpg_600x600.jpg 第二次他又用了一个硬纸壳进行尝试，过程也同样顺利，切割效果也跟之前一样。 http://static.cnbetacdn.com/thumb/article/2016/0822/24faf1dc528f03a.jpg_600x600.jpg 试完了白纸，他就把材料换成木片，虽然边缘有些烧焦，但锯面依然光滑。 http://static.cnbetacdn.com/thumb/article/2016/0822/966f7ec0b8ae398.gif_600x600.gif http://static.cnbetacdn.com/thumb/article/2016/0822/2d13cf5abbf18a8.jpg_600x600.jpg http://static.cnbetacdn.com/thumb/article/2016/0822/972b8fb6b0e82cf.jpg_600x600.jpg http://static.cnbetacdn.com/thumb/article/2016/0822/ff4f8e7d12eb3ec.jpg_600x600.jpg 当然，受其材质硬度的限制，这个纸锯子功能也是有限的。他曾试着用这个薄薄的纸刀片去切割铝片，但只能起到打磨边缘的效果，并未能切开铝片。所以它不能切开比木块更硬的材质。 通过这个实验也开始让人了解到，纸其实也可以很锋利。其中的原理和压强有关。一个物体的边缘越薄，受力面积就越小，受到相同大小的力的时候，压强也就变大了。所以如果使用得当，一张脆弱的纸张也有可能成为一把利刃。# Joke - 肚皮舞运动

Will the foam pie incident change everything?
More than anything Rupert Murdoch or his son James said before the
Parliamentary panel on Tuesday, it may be the attack on Murdoch—and his
wife literally leaping to his defense—that changes public opinion about the
scandal that has led to the closing of The News of the World and the
resignations of top News Corp [NWSA 15.7511 0.7861 (+5.25%) ]
officials.
A man who had sat through the long, and often boring, testimony approached
the 80-year-old Murdoch toward the end of the hearing, swore at him, and
attempted to strike him with a pie plate filled with foam.
“You naughty billionaire,” the attacker supposedly said.

Rupert Murdoch: 'This Is the Most Humble Day of My Life'
Former Murdoch Aide Rebekah Brooks Arrested
Everyone nearby jumped to their feet in a flash. But Murdoch’s wife Wendi
leapt over others between her and her husband’s attacker, returning the
attack with her own slap. She reportedly then picked up the plate and tried
to strike the attacker. Then, as others grappled with the attacker, she
moved back to see to her husband.
It was all over in less than a minute. But those moments most likely swayed
the sympathies for a few viewers toward the Murdochs.
Almost instantly, people were referring to her as “Tiger Wife,” a play on
the title of Amy Chua’s book, "Battle Hymn of the Tiger Mother," which
argues for the superiority of Chinese-style parenting over soft, Western
parenting.
I know I felt nothing but admiration for the love between Wendi and Rupert.
They aren’t ultra-wealthy media moguls. They certainly aren’t the evil-
doers that many of their enemies have portrayed. They are a couple with a
fierce loyalty between them. And Wendi, well, who wouldn’t want someone
with those instincts on your side?
Murdoch came into the hearing looking to many like a potential villain. And
now he leaves beside a wife who looks positively heroic.
You’d have to have a hard place where your heart should be not to be
cheering for the Murdochs a bit right now.
