What does it take to make yourself anonymous online? The Internet was made for sharing information, after all — concealing your communications and identity ain’t easy. We’re joined by Ben of Stuff They Don’t Want You to Know to break down why it’s so difficult and what lengths you’d have to go to if you wanted to surf truly anonymously.
reblogging here because i can see this being relevant to anyone who’s ever tried to get out of an abusive relationship
Reblogging because that last comment made me reread the whole thing in a new light and realize this could be vital information. So, putting it out there for everyone, and hoping no one ever really needs it.
Metamaterials are stuff that we humans have made — you won’t find them in nature. And these materials are made in such a way that they can have properties that are either really uncommon or don’t occur at all in the natural universe as we know it.
See, conventional materials have properties that are determined by the individual atoms and molecules they are made of. In other words, a gold brick’s properties are due to all those wacky gold atoms. The chemical composition of the material gives it its properties.
But metamaterials get their properties not from the kind of atoms inside them but from their physical structure. It’s not the chemical composition that matters — it’s how the atoms are physically stacked together and patterned within the metamaterial.
They’re built to interact with electromagnetic radiation and physical force in weird and wonderful ways, and may eventually make sci-fi stuff like cloaking devices (and impossible-sounding things like a substance that expands when you squish it and contracts when you stretch it) possible.
