Ìý"As the days and months pass, Radio 4 takes me on an epic voyage throughout the depths of human knowledge, human experience and unfettered imagination. From this Ìýsmall sceptred isle to vast views of distant lands. From the Ìýone world to the many worlds we all share; from the tiniest molecule to the very nature of the universe and beyond. And then, at last, after the fears, the tears, the Ìýwonder. And belly-aching laughter, the painting is done, the brushes are cleaned and Sailing By echoes the close of day."
