Freeman Dyson said this quote

We must be careful not to discourage our twelve-year-olds by making them waste the best years of their lives preparing for examinations.

~ Freeman Dyson

It is our task, both in science and in society at large, to prove the conventional wisdom wrong and to make our unpredictable dreams come true

~ Freeman Dyson

The essential fact which emerges ... is that the three smallest and most active reservoirs ( of carbon in the global carbon cycle), the atmosphere, the plants and the soil, are all of roughly the same size. This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.

~ Freeman Dyson

A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible.
