## Main Question or Discussion Point

Ok, I knew that Heisenberg had studied under Arnold Sommerfeld, but I have just now learnt that Sommerfeld proposed a sort of uncertainty principle in the first Solvay meeting.

That was 1911.

It seems that he proposed that the time needed to transfer a quantity of energy was inversely proportional to this quantity, and perhaps that the space needed to transfer some momentum was inversely proportional to this momentum. IE:

[tex]

\Delta t = { h \over \Delta E}

[/tex]

and perhaps

[tex]

\Delta x = { h \over \Delta p}

[/tex]

I wonder if there was some extension of this idea before coming to Heisenberg himself (and his principle). After all, from 1911 to 1927 there is some time lag. Also, I wonder how compatible is this idea with the later developed Quantum Mechanics.

Is there some book naming explicitly this formulation?
