Heisenberg and his Uncertainty principle.

Sir Arthur Eddington wrote:
We used to think that if we knew one, we knew two,
because one and one are two. We are finding
that we must learn a great deal more about `and'.
Why?
Because one is can be different from one.
Take electron - symbol (e)
Take proton - symbol (p)
They are absolute different particles.
And interaction between electron and proton
is not the same than interaction between
proton and electron:
ep ≠ pe ( non - commutative algebra,
Heisenberg and his Uncertainty principle.)
===================
Another example:
A thing called “shoe” and a thing called “ sock” along with
the operator ”and” which combines “shoe” and “sock” things.
If you play around with it, you will find
that the “ order “ is fairly important.
