What lies behind the phenomenal progress of physics in the last few centuries ?

Explanation

`to` Great progress usually accompanies changes in our basic perceptions.
`to` First, it was realized that for scientific progress, only qualitative thinking, though no doubt important is not enough.
`to` Quantitative measurement is central to the growth of science, especially physics because the laws of nature happen to be expressible in precise mathematical equations.
`to` The second most important insight was that the basic laws of physics are universal the same laws apply in widely different contexts. Lastly, the strategy of approximation turned out to be very successful.
