Poem of theoretical complexity…..

Nature and Nature’s law hid in night

God Said “Let Newton be: and all was light,

It did not last: the Devil howling “Ho!

Let Einstein be!” restored the status quo. 

The first two lines are written by Alexander pope in praising Sir Issac Newton’s theory of gravitation but an anonymous wordsmith added the last two lines showing the praise was short lived by the inadequacies of Newton’s Law in explaining gravity and its related subjects. Albert Einstein’s theory of relativity, more complex and more accurate mathematical and theoretical description of gravity restores order to the problems in understanding gravity.
