Information ExplosionInformation Explosion Information doubles every 5 years Why? What has contributed to this
exponential growth?– 1. New answers to scientific questions (which generates
more questions and answers)– 2. Bureaucracy in government and life
Our challenge: How to manage and make useful this information
