Final Word

This week's Final Word comes from a fantastic mathematician:

"Lastly, she pictured to herself how this same little sister of hers would, in the aftertime, be herself a grown woman; and how she would keep, through all her riper years, the simple and loving heart of her childhood; and how she would gather about her other little children, and make their eyes bright and eager with many a strange tale, perhaps even with the dream of Wonderland of long ago; and how she would feel with all their simple sorrows, and find a pleasure in all their simple joys, remembering her own child-life, and the happy summer days."

There was no winner last week for Edwin Hubble's The Realm of the Nebulae , so the winner of this week's competitition will receive two £20 book tokens.
