“As every historian of science in the last hundred years has pointed out, scientists use all sorts of aids and intuitions and stories and metaphors to help them in their quest of getting their speculative model to fit ‘nature’…. My physicist friends are fond of the remark that physics is 95 percent speculation and 5 percent observation. And they are very attached to the expression ‘physical intuition’ as something that ‘real’ physicists have: They are not just tied to observation and measurement but how to get around in the theory even without them.”
