Orders of Magnitude (specific Energy Density)

This is a table of specific energy densities by magnitude. Unless otherwise noted, these values assume standard ambient temperature and pressure.

Famous quotes containing the words orders, magnitude and/or energy:

    “Let’s start with the three fundamental Rules of Robotics.... We have: one, a robot may not injure a human being, or, through inaction, allow a human being to come to harm. Two, a robot must obey the orders given it by human beings except where such orders would conflict with the First Law. And three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.”
    —Isaac Asimov (1920–1992)

    “My time has come.
    There are twenty people in my belly,
    there is a magnitude of wings,
    there are forty eyes shooting like arrows,
    and they will all be born.
    All be born in the yellow wind.”
    —Anne Sexton (1928–1974)

    “Violence among young people ... is an aspect of their desire to create. They don’t know how to use their energy creatively so they do the opposite and destroy.”
    —Anthony Burgess (b. 1917)
