This behaviour may involve the strange properties of quantum mechanics. According to quantum mechanics, particles can occupy two states at the same time.

In this way, the strange behaviour of our material could be explained by the fact that we’ve discovered a new quantum state that fluctuates between being a metal and an insulator.

It could also be that we have discovered a new quantum phase of matter.

3-D Printed Gun Lawsuit Starts the War Between Arms Control and Free Speech

THIS WEEK MARKS the two-year anniversary since Cody Wilson, the inventor of the world’s first 3-D printable gun, received a letter from the State Department demanding that he remove the blueprints for his plastic-printed firearm from the internet. The alternative: face possible prosecution for violating regulations that forbid the international export of unapproved arms. Now Wilson is challenging that letter. And in doing so, he’s picking a fight that could pit proponents of gun control and defenders of free speech against each other in an age when the line between a lethal weapon and a collection of bits is blurrier than ever before.
