Famous quotes containing the words magic and/or number:
“I revere the memory of Mr. F. as an estimable man and most indulgent husband, only necessary to mention Asparagus and it appeared or to hint at any little delicate thing to drink and it came like magic in a pint bottle; it was not ecstasy but it was comfort.”
—Charles Dickens (1812–1870)
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
