Hello student,

I hope you are doing good.

The physical world is exceptionally unpredictable and complex. Similarly, the Biological World has its own complexities. It has immense significant degrees in regard of mass, length and time. And, after its all said and done all the actual wonders can be clarified as far as scarcely any essential standards of material science. In Layman's terms, inspite of all this, all the physical phenomena can be expressed in terms of few basic laws. This is the thing that Einstein intended to state.

I hope you find it useful.
