anti-determinism-law

Here is another interesting quote read online (Author: William Bogaerts)

A timeline is going to be difficult, even if you know _all_ the details
beforehand. You know, there is an "anti-determinism-law" in physics
that
says you cannot know both the position and speed of a particle exactly.
There's a similar law in software engineering that says you cannot know
the effort and the requirements together exactly.
