Re: Free form/Chaos Thread
“On his deathbed, my grandpa told me three things to remember for after he died. First he said, "You can't own a cat. Ever." Second he told me, "Friendly boys make friendly friends." Finally he said, "You were adopted, just like your father before you, and his father before him." "So," I said, "you were adopted?" "Of course not!" he replied. "Your father's not my son, just like he's not your father." And to this day I am still confused. I have no idea why I can't own a cat.”

Re: Free form/Chaos Thread
Australian scientists have recreated a famous experiment and confirmed quantum physics's bizarre predictions about the nature of reality, by proving that reality doesn't actually exist until we measure it - at least, not on the very small scale.
That all sounds a little mind-meltingly complex, but the experiment poses a pretty simple question: if you have an object that can either act like a particle or a wave, at what point does that object 'decide'?
Our general logic would assume that the object is either wave-like or particle-like by its very nature, and our measurements will have nothing to do with the answer. But quantum theory predicts that the result all depends on how the object is measured at the end of its journey. And that's exactly what a team from the Australian National University has now found.
"It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it," lead researcher and physicist Andrew Truscott said in a press release.
Known as John Wheeler's delayed-choice thought experiment, the experiment was first proposed back in 1978 using light beams bounced by mirrors, but back then, the technology needed was pretty much impossible. Now, almost 40 years later, the Australian team has managed to recreate the experiment using helium atoms scattered by laser light.
