Blast-Proof Fabric Resists Multiple Explosions

An anonymous reader tips a Gizmodo story on a fabric whose properties are counterintuitive, to say the least of it. "Zetix is a fabric so strong it will resist multiple car bomb blasts without breaking. It absorbs and disperses the energy from explosions... it can be used in body armor, window covering, military tents, and hurricane defenses... [and] it can be used as medical sutures that won't damage body tissue. All of this is thanks to a property that apparently defies the laws of physics: helical-auxetics, objects that actually get fatter the more you stretch them. The concept makes my head want to explode, but when you see it in action it actually makes sense."

"All of this is thanks to a property that apparently defies the laws of physics"

These kind of statements are so frustrating to me...

"Defies the laws of physics"

[cephyn]

I really hate that saying. It makes it sound like physics is a religion, where scientists have decided "that's how things work, and that's that" - which is ridiculous. If something "defies" physics, then the laws of physics change to accommodate reality. That's how science works - it comes about based on observation.

Nothing can defy the laws of physics - because physics describes how things work.

you just proved your own stupidity

a few things your intellect hasn't realized yet:

1. menace comes from smart and ill-intentioned people as well as just dumb people
2. that tools of war are used by men engaging the defense from those with bad intentions just as much as it is used by those with bad intentions

thought experiment for you: a lunatic comes into town with a samurai sword and starts slashing people. reference recent news from omaha nnebraska if you think this scenario is not a constant danger throughout human existence

1. in society #1, the people calmly stand there, explaining to him, much in your line of thought, of the stupidity of what he is doing. shortly before their jugulars are slashed. the whole town is wiped out. also wiped out with them, is the philosophy of nonviolence

2. in society #2, as soon as the guy raises his sword, a common townsfolk raises his sword, and the only blood spilled is that of the lunatic. the philosophy of prudent use of arms survives

interestingly enough, the philosophy of nonviolence results in more bloodletting and death (scenario #1). paradoxical, but true

darwinistically speaking, nonviolence is a path to extinction. it sounds really nice, but in the reality of human nature and how human nature plays out, you must, UNFORTUNATELY (see, no warmongering here) have constant use of arms close by, to guard from those with bad intent. you will never stop the creation of people with bad intent in this world. if you respect free will, you respect that every once in awhile, someone somewhere will make a horrible choice, and you must guard against that. i suppose you could disallow free will. that's a certain path to nonviolence: a superfascist state. is that superior in your mind than a free but armed society?

peace in this world is not maintained by an absence of armament, peace in this world is maintained by a balance of armament, a constant tension, a potential that is released to restore the balance of peace when an imbalance in fair action occurs by bad intentioned individuals in public settings
