El tamaño y la edad del Cosmos superan la comprensión normal del hombre. Nuestro diminuto hogar planetario está perdido en algún punto entre la inmensidad y la eternidad. En una perspectiva cósmica la mayoría de las preocupaciones humanas parecen insignificantes, incluso frívolas. Sin embargo nuestra especie es joven, curiosa y valiente, y promete mucho. En los últimos milenios hemos hecho los descubrimientos más asombrosos e inesperados sobre el Cosmos y el lugar que ocupamos en él; seguir el hilo de estas exploraciones es realmente estimulante. Nos recuerdan que los hombres han evolucionado para admirarse de las cosas, que comprender es una alegría, que el conocimiento es requisito esencial para la supervivencia. Creo que nuestro futuro depende del grado de comprensión que tengamos del Cosmos en el cual flotamos como una mota de polvo en el cielo de la mañana.

She was a wonder junkie. In her mind, she was a hill tribesman standing slack-jawed before the real Ishtar Gate of ancient Babylon; Dorothy catching her first glimpse of the vaulted spires of the Emerald City of Oz; a small boy from darkest Brooklyn plunked down in the Corridor of Nations of the 1939 World’s Fair, the Trylon and Perisphere beckoning in the distance; she was Pocahontas sailing up the Thames estuary with London spread out before her from horizon to horizon. been voyaging between the stars when the ancestors of humans were still brachiating from branch to branch in the dappled sunlight of the forest canopy. Drumlin, like many others she had known over the years, had called her an incurable romantic; and she found herself wondering again why so many people thought it some embarrassing disability. Her romanticism had been a driving force in her life and a fount of delights. Advocate and practitioner of romance, she was off to see the Wizard.

Dreams are associated with a state called REM sleep, the abbreviation standing for rapid eye movement. The REM state is strongly correlated with sexual arousal. Experiments have been performed in which sleeping subjects are awakened whenever REM state emerges, while members of a control group are awakened just as often each night but not when they're dreaming. After some days, the control group is a little groggy, but the experimental group - the ones who are prevented from dreaming - is hallucinating in daytime. It's not that a few people with a particular abnormality can be made to hallucinate in this way; anyone is capable of hallucinations.
