Wine/water Mixing Problem

In the wine/water mixing problem, one starts with two barrels, one holding wine and the other an equal volume of water. A cup of wine is taken from the wine barrel and added to the water. A cup of the wine/water mixture is then returned to the wine barrel, so that the volumes in the barrels are again equal. The question is then posed—which of the two mixtures is purer?

The problem can be solved without resorting to computation. It is not necessary to state the volumes of wine and water, as long as they are equal. The volume of the cup is irrelevant, as is any stirring of the mixtures. Also, any number of transfers can be made, as long as the volume of liquid in each barrel is the same at the end.

Famous quotes containing the words wine, water, mixing and/or problem:

    A rake is a composition of all the lowest, most ignoble, degrading, and shameful vices; they all conspire to disgrace his character, and to ruin his fortune; while wine and the pox content which shall soonest and most effectually destroy his constitution.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.
    Elaine Heffner (20th century)

    Give me Catholicism every time. Father Cheeryble with his thurible; Father Chatterjee with his liturgy. What fun they have with all their charades and conundrums! If it weren’t for the Christianity they insist on mixing in with it, I’d be converted tomorrow.
    Aldous Huxley (1894–1963)

    What had really caused the women’s movement was the additional years of human life. At the turn of the century women’s life expectancy was forty-six; now it was nearly eighty. Our groping sense that we couldn’t live all those years in terms of motherhood alone was “the problem that had no name.” Realizing that it was not some freakish personal fault but our common problem as women had enabled us to take the first steps to change our lives.
    Betty Friedan (20th century)
