Planetary Science Letters

Famous quotes containing the words planetary, science and/or letters:

    We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.”
    Barbara Ward (1914–1981)

    The science of constructing a commonwealth, or renovating it, or reforming it, is, like every other experimental science, not to be taught a priori. Nor is it a short experience that can instruct us in that practical science, because the real effects of moral causes are not always immediate.
    Edmund Burke (1729–1797)

    The entire merit of a man can never be made known; nor the sum of his demerits, if he have them. We are only known by our names; as letters sealed up, we but read each other’s superscriptions.
    Herman Melville (1819–1891)
