    Newtonian fluids
    These fluids have flow properties that change depending on conditions, with some becoming more viscous, while others become less viscous.

    as in they do not fit the Newtonian constant coefficient for viscous fluids, either thinning or thickening. So blood can indeed be a NF.
    A fluid that requires a different calculation other than the Newtonian constant coefficient is therefor a NFF by definition as time is a factor the Newtonian coefficient doesn't account for


    Is this a contentious scientific argument? <whistle>

    No, it's just the exact same thing I said about a day ago:

    You said blood is not a NFF, you were 100% wrong so how did you say exactly that?

    FYI I'd read the thread earlier and there was nothing of interest and I knew my mere presence would probably provoke a barking reaction, so i left it alone.

    I then popped back and saw the discussion about blood etc and found it vaguely interesting, I saw the comment that you'd made about glass, but decided not to comment as I thought you'd go melty.

    So when I saw that you'd already gone melty in response to astro correcting you, I thought wtf, I might as well correct him on the glass thing and laugh at him failing to last 24 hrs without reverting to #standard behaviour.

    either talk to me about the topics, any topics or dont bother mate. I dont want this thread going like the other thread with all that conspiracy lool and like fest bollocks.

    Some rational discussion without the ****e for once

    I said it wasn't non-Newtonian in the same way as cornstarch.

    Read the first 3 words of the second sentence:

    No one ever said it was the same as cornstarch, I clearly, if you read related it to TDS, postulating like, which seemed to offend you. Only after of course that first post, leave bitterness at the door and it might just go well/

    Unfortunatley it has gone that way already.

    Science discussion as pointed out earlier will always give a difference of opinion, like relegion or politics.

    Still not having it that glass is a fluid.

    I've tried. I posted the latest research on the glass fluid / solid debate that's been debated for donkeys years and is actually quite interesting.

    Middleweight black hole suspected near Milky Way’s center
    Turbulent gas cloud suggests presence of strong gravitational influence

    COSMIC CONTENDER A black hole (illustrated) weighing the same as roughly 100,000 suns might be stirring up a gas cloud near the center of the Milky Way.

    TOMOHARU OKA/KEIO UNIV.

    SPONSOR MESSAGE
    The supermassive black hole at the center of the galaxy might have a middleweight neighbor, a new study suggests. If this partner exists, it would be the second most massive black hole known in the Milky Way.

    A black hole weighing the same as about 100,000 suns could explain why gas in an interstellar cloud is swirling around at hundreds of kilometers per second, researchers suggest. Tomoharu Oka, an astrophysicist at Keio University in Yokohama, Japan, and colleagues present the findings in the Jan 1. Astrophysical Journal Letters.

    Intermediate mass black holes — between 100 and 1 million times as massive as the sun — are highly sought after but hard to find. They might help researchers understand the relationship between black holes with the mass of a few suns and the behemoths that are up to several billion times as massive. Astronomers have yet to turn up definitive evidence for an intermediate black hole, though some blazing sources of X-rays seen in other galaxies are candidates.

    This new candidate and its host cloud sit in the Milky Way’s nucleus, about 25,000 light-years away in the constellation Sagittarius. Just 200 light-years from the pair lies the region’s gargantuan black hole, weighing in at roughly 4 million suns. Oka and colleagues discovered the turbulent cloud using the Nobeyama Radio Observatory in Japan. Searches through old X-ray and infrared images for the source of the turbulence turned up nothing. Given how tiny and massive the culprit must be, the researchers argue that the cloud is passing by an invisible intermediate mass black hole whose gravity is stirring up the gas.

    There are a couple of problems with this interpretation, says Cole Miller, an astrophysicist at the University of Maryland in College Park. As a black hole with this much mass plows through an interstellar cloud, it should generate radiation about one billion times as bright as the sun. And given that the black hole would spend only about 10,000 years passing through the cloud — an eyeblink on cosmic timescales — the odds of finding the two together are pretty low. “We would have to be remarkably lucky,” he says.

    Oka says he plans to keep an eye on the cloud for any flashes triggered by gas colliding around the putative black hole. If it’s there, “we expect faint X-ray emission or a kind of flare-up,” he says.

    Well there are those that say no and those that say yes so it's up for debate alright, without getting all argumentative about it. Not that I mean you.

    Windows and glass wear of age flows down towards the direction of gravity. If it is moving it is a fluid imo, a very slowly moving one. Windows made flat change shape, you can see drooping in really old glass. So it must move. I think some solid plastics are also considered fluids

    I dont really understand the movement of glass though, never looked at it. Dunno if it is constant but it certainly does move

    about 200 years, and it wont be the exact same shape as when you put it in

    Who would leave a glass for alcohol alone for so long? Is that not just down to the weight / deformation of the glass? You could say its down to flow, or that it has no crystaline structure and the material can deform......not flow?

    Dear all.

    In case there is any confusion glass does display fluidic properties

    Over time it slowly flows with gravity and window panes can be measured as thicker at the bottom.

    Now this could be another schism in the church so people need to cool off for a couple days.

    And yeah I'm a ****... Sue me.

    old galss is interesting. the bottle bottom effect glass was made by spinning the glass in a disk when blown.

    plate glass was made by making a blown cylinder of glass, cutting ends off and then opening and folding the panel flat under heat. quite interesting but you can see the ripples in old glass.

    modern glass is rolled

    It does flow kind of like a glacier flows kind of but looks solid as anything i suppose.

    glass is quite interesting. I deffo agree there was no way panels of glass were ever even or flat in those days.

    here is an article from a geeky since hick in nebraska quoting lots of sources

    interesting http://dwb.unl.edu/Teacher/NSF/C01/C01Links/www.ualberta.ca/~bderksen/florin.html

    Thus I'll change my mind and say glass is in fact a solid and prove that you can learn something new every day!
