Science is what we call the explanations for the many accurate measurements that technologists have discovered; especially physical constants. I learned this from Niels Bohr in a class at the U. of Chicago. Technology is a truly empirical field. Bridges fall down and engineers learn from it.
- Surgery is 2,500 years old. It is truly a skill with knowledge and training that is passed on. Medicine is recent, 100 years since sulfa-thiozole. Still filled with witchcraft and voodoo. Most medical published studies are statistically inadequate and poorly designed.
- Humans are primates and they only learn in childhood which ends at roughly age 23. Maybe 1 out of 300 people actually learn significantly new material after age 23.
- Modern commerce is 90% cooperation and 10% competition.
- Many cultural attributes are probably genetic. Many cultures are old enough to inscribe some widespread behavior in the genes.
- Most management and personnel problems go away with time, but a few need immediate attention before they get worse.
- When measuring human or any real world phenomenon 95% is the equivalent of 100%, there is always noise in real world measurements.
