    Greener Chemistry

    Call me a nerd, but this is totally cool on so many levels: http://www.nytimes.com/2016/07/19/sc...chemistry.html

    The technique, based on so-called mechanochemistry, or chemistry driven by mechanical force, is radically different from the traditional way of dissolving, heating and stirring chemicals in a solution. Removing solvents could help make many chemical processes used by industry more environmentally friendly.
    (snip)
    Many commonly used solvents, like chloroform, acetone and hexane, are harmful and volatile, posing risks to people who inhale them as well as the environment. Solvents also make up the vast majority of chemical waste, and consume most of the energy used in a chemical reaction.But because solvents have been the norm for centuries, many chemists tend to doubt the viability of mechanochemistry. “We learn that solution is just the way to go,” Dr. Mack said, “and never think about alternatives.”
    The green chemistry movement has motivated some chemists to ditch the old solution methods in favor of mechanochemistry.

    “You have never answered but you did not need to. If I stand at the ocean I can hear you with your thousand voices. Sometimes you shout, hilarious laughter that taunts all questions. Other nights you are silent as death, a mirror in which the stars show themselves. Then I think you want to tell me something, but you never do. Of course I know I have written letters to no-one. But what if I find a trident tomorrow?" ~~Letters to Poseidon, Cees Nooteboom

    “We still carry this primal relationship to the Earth within our consciousness, even if we have long forgotten it. It is a primal recognition of the wonder, beauty, and divine nature of the Earth. It is a felt reverence for all that exists. Once we bring this foundational quality into our consciousness, we will be able to respond to our present man-made crisis from a place of balance, in which our actions will be grounded in an attitude of respect for all of life. This is the nature of real sustainability.”
    ~~Llewellyn Vaughan-Lee

    "We are the offspring of history, and must establish our own paths in this most diverse and interesting of conceivable universes--one indifferent to our suffering, and therefore offering us maximal freedom to thrive, or to fail, in our own chosen way."
    ~~Stephen Jay Gould, Wonderful Life: The Burgess Shale and the Nature of History

    "Humans are not rational creatures. Now, logic and rationality are very helpful tools, but there’s also a place for embracing our subjectivity and thinking symbolically. Sometimes what our so-called higher thinking can’t or won’t see, our older, more primitive intuition will." John Beckett

    That is cool. I didn't even know it was possible!
    Those who have suffered understand suffering and therefore extend their hand.

    I can't do everything, but I can do something.
