Bang But No Splash

BishopBerkeley writes "When a drop of ethanol is dropped on a surface at low pressures (1/5 atmosphere or less), it makes no splash. Science offers a brief synopsis and fascinating pictures of the phenomenon. The results seem to confirm the (perhaps counterintuitive) prediction that more viscous liquids are more likely to splash, not less likely . Links to the researchers' home page at U of Chicago (as of now, the site is timing out) and pdf version of the article on arxiv can be found on the Science page also."

    A nuclear bomb can be detonated by taking two lumps of metal and banging them together real fast. The romans could have done that, easily.

    In the Deccan plain of India, we
    find cities made of sun-dried bricks that are glassified on one side, and significantly radioactive.

    I don't know if Gurkha in his vimana used intermittent wipers, but he seems to have witnessed
    something similar to a nuclear device in its
    energy release, as we read in the Mahabharata: ...a single projectile
    Charged with all the power of the Universe.
    An incandescent column of smoke and flame
    As bright as the thousand suns
    Rose in all its splendour... ..it was an unknown weapon,
    An iron thunderbolt,
    A gigantic messenger of death,
    Which reduced to ashes
    The entire race of the Vrishnis and the Andhakas. ..The corpses were so burned
    As to be unrecognisable.
    The hair and nails fell out;
    Pottery broke without apparent cause,
    And the birds turned white.

    After a few hours
    All foodstuffs were infected... ...to escape from this fire
    The soldiers threw themselves in streams
    To wash themselves and their equipment...

    Maybe it's just cheaper in the long run to buy a vaccuum-insulated stainless steel tank than it is to deal with bulky, deteriorating insulating products. I'll bet that the annular space and the ullage is also purged with nitrogen, if not being an actual vaccuum space.

    Liquid oxygen, liquid nitrogen and liquid hydrogen is transported this way. You probably pass or see some of these tankers on the road every day.
