People, trucks and even military tanks have tried and failed the task of pulling apart two phone books lying face up with their pages interleaved, like a shuffled deck of cards. While physicists have long known that this must be due to enormous frictional forces, exactly how these forces are generated has been an enigma – until now.
A team of physicists from France and Canada has discovered that it is the layout of the books coupled with the act of pulling that is producing the force.

They'll fail. You know... "information wants to be free" and all that jazz; besides the phone books are replaced by apps for tablets - good lock... errr.... I mean, good luck interleaving those tablets.

You're missing the point! which is to make deceptively strong fences out of paper! Think of the Chinese Finger Trap in fence form.

I'm not. Actually, I'm pretty happy to make it my own signature, if I could figure out how to protect it as my own(... naaah. Doesn't worth the effort)
Besides, there is an almost subliminal but serious point that I may wanted to make in my original reply [soylentnews.org]: people today are less sensitive to physical gathering, the freedom on speech moved quite a lot on the net. Which means if the people really care enough to gather, some flimsy phone books will stop them - just throw some gasoline over them then use an app to fire it up (grin)
If they really want to stop them, they'll need to disrupt their phone/tablet communication (build their tablet locks instead of phonebook lock).
S'rely**... if people really care, good luck with that [newscientist.com]
