In case of a ball moving in air, the laws governing are action and reaction and Newton explained it.
In case of an electron’s movement, the governing laws posit uncertainty and Heisenberg did not say action or reaction.
In algebra, we call something x and after analysis, we find the X.
In calculus, the same x , y now become dy/dx and these cannot be found out. You have find them out in a mental space. Then you squeeze them mentally into such a small proportion that our mind breaks !
We can see one’s physcial body but cannot see mind, intelligence and the core of personality – false ego. But they are there. We feel this and this assumption lies at the root of all communication.
