Bob Metcalfe on Knowledge

Speaking at PopTech! 2005, Bob Metcalfe, inventor of the Ethernet (and a constant presence at PopTech! since 1997), explained the three facets of knowledge:

1. science -- gathers knowledge
2. technology -- applies knowledge
3. education -- transfers knowledge

Of course, he also justified his being overweight, explaining how it helps compensate for his natural human tendency of being promiscuous and a hunter-killer.
