Planck’s Constant

I don’t know why
My predictions have uncertainty
And that is ±1

In quantum mechanics (QM) though
Uncertainty relation (UR) has a minimum
And that is hbar/2
hbar, therefore, is 2

Note the 2
It is the first prime
Note again the 2!
In language
‘!’ is for feelings
It is factorial in math though
hbar, therefore, is 2!

Recall the UR
It has a minimum
And that is 2!/2
It is the first order UR
nth order UR would, therefore, be p_n !/p_n
