Isidor I. Rabi, the Nobel laureate in physics was once asked, ''Why did you become a scientist, rather than a doctor or lawyer or businessman, like the other immigrant kids in your neighborhood?''

Dr. Rabi's answer was profound: ''My mother made me a scientist without ever intending it. Every other Jewish mother in Brooklyn would ask her child after school: 'So? Did you learn anything today?' But not my mother. She always asked me a different question. 'Izzy,' she would say, 'did you ask a good question today?' That difference - asking good questions -made me become a scientist!''
