So you think your being a physicist gives you special insight into whether Sommerfeld, Born and Heisenberg understood the significance of what they were working on? Explain.

Yes, of course. I am an expert in physics, you are not...

That's not an explanation, that's a rather trite attempt at an ad-hominem evasion. What (and how) does your exhaustive knowledge of physics allow you to conclude about how Sommerfeld, Born and Heisenberg viewed the significance of what they were working on, that you assume is not available to me? Use whatever physics is necessary to explain how you came to your position - I might know more than you assume.
