Freeman Dyson, "A Quiet Stroll In Ramanujan's Garden"

"Whenever I am angry or depressed, I pull down the collected papers from the shelf and take a quiet stroll in Ramanujan's garden. I recommend this therapy to all of you who suffer from headaches or jangled nerves. And Ramanujan's papers are not only a good therapy for headaches, they also are full of beautiful ideas which may help you to do more interesting mathematics" --Freeman J. Dyson, "A Walk Through Ramanujan's Garden"
