Positive Minkowski Length

Famous quotes containing the words positive and/or length:

    Blessed be the inventor of photography! I set him above even the inventor of chloroform! It has given more positive pleasure to poor suffering humanity than anything else that has “cast up” in my time or is like to—this art by which even the “poor” can possess themselves of tolerable likenesses of their absent dear ones. And mustn’t it be acting favourably on the morality of the country?
    Jane Welsh Carlyle (1801–1866)

    Nor had I erred in my calculations—nor had I endured in vain. I at length felt that I was free.
