Category Chemistry

Famous quotes containing the words chemistry and/or category:

    ...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.
    Ellen Henrietta Swallow Richards (1842–1911)

    Despair is typical of those who do not understand the causes of evil, see no way out, and are incapable of struggle. The modern industrial proletariat does not belong to the category of such classes.
    Vladimir Ilyich Lenin (1870–1924)
