Knowledge is Exploding at 2000 Pages a Minute

Knowledge is exploding at such a rate-more than 2000 pages a minute-that even Einstein couldn’t keep up. In fact, if you read 24 hours a day, from age 21 to 70, and retained all you read, you would be one and a half million years behind when you finished. How can it be, in a world where half the things a man knows at 20 are no longer true at 40-and half the things he knows at 40 hadn’t been discovered when he was 20?  (Campus Life, Feb., 1979).
