    First Quantum Effects Seen in Visible Object - Physics - io9

    Okay, not a cat, but a 60 micrometre strip of metal at 25 millikelvins has demonstrated quantum superposition in a non-quantum-scale object.

    By the way, those of us who understand the nuances of this, get a load of the comments on the page, particularly one "BigManMalone".

    I think it makes his widdle brain hurt. :dunce 

    Still, awesome confirmation that all objects very likely do simply follow the same physical laws regardless of scale and only beyond certain scales is the "interference" around them causing collapse to one state or another.

    Can someone explain to me in the simplest way possible what Schrodinger's cat is? I've read it 1,000 times from Wikipedia to my science textbooks and I haven't the slightest clue what it is.

    I was just reading this today too, was considering posting about it here but I didn't quite understand the entire thing. It's fascinating though.

    (Insert witty sciency remark here) Hey, it's midnight-ish. My brain's long since turned off.

    Dammit, the waveform collapsed when I opened the thread...

    I am pretty ignorant of Quantum mechanics, but I'll play diplomat and state the Universe is probably deterministic.

    While fascinating, it only suggests to me a further layer of complexity currently beyond understanding. I am not yet convinced of the perceived implications.

    BigManMalone's comments are interesting; though one would think using laws of non-contradiction in order to break or fault said laws would be enough to cast some doubts on the established, assumed application of the principles to the process would inherently distort any outcome if they weren't actually applicable.

    So contradiction would be contradicted? sounds like a conundrum to me.

    The following illustration conveys my opinion:

    read wikipedia again.

    Schrödinger's cat - Wikipedia, the free encyclopedia

    read the box on the right. it's very simple.

    I still don't get it. A cat can never ever be dead and alive at the same time. There will never be a state of transition where a cat can have both states. That's why I will never understand what they try to tell us.

    Thats the point - the thought experiment was meant to show that objects in the macroscopic world don't seem to act the same as quantum theory predicts happens to the smallest particles.

    The point of the thought experiment is just that. Sort of. He wasn't actually trying to say that the cat is both alive and dead--but by linking the cat's life to an atomic event (which can simultaneously be 1/0 or Y/N or whatever, at least according to quantum theory), then you're entangling the cat's state with the quantum state of the radioactive material.

    The implication of this experiment, then, is that maybe Schrodinger's cat isn't as absurd as he thought. Maybe. Obviously, it's still a leap from nano-scale oscillation to zombie cats...but not as much of a leap as it was in 1935.

    Schroedingers cat= It's both and neither until observed. Wave transistion state. Oddly, I only now about this from watching Prince of Darkness.

    Oh wow, I actually understand this now! It's basically about how you can't make assumptions about something and declare it as fact until you have solid proof, which is really sort of an obvious answer, come to think of it. Did I get that right?

    I love you so much right now :lolol 

    Thanks. I've probably learned more (And in a much easier way) by watching The Big Bang Theory than I have in my Chemistry class this year.

    This is a good step toward the development of The Mentaculus.

    That said, what are you and CdnShockwave trying to do to the GD with these science articles the past couple of days? They're far too complex for people to have developed personal opinions that obfuscate tedious facts and place world-view affirming emotive responses on a par with anything an "expert" produces. Teach the controversy, else the discussion will remain imperfect!

    There's a part of me that's in state of 'awesome', yet at the same time, there's a part of me that is confused and doesn't really care.
