Does QED have six figure precision for dense matter physics,.. quantities? NO.

Re QED. Perhaps you don't consider the very many experimental results accurately predicted?

THHuxleynew asserted that QM had six figure precision for the neutron-proton

n-p mass difference... mass splitting.... but couldn't find it

.

Then he found 3.5 figure precision in the arxiv paper

in this post.. where he advised to *"look at the predictions here*" Figure 2 Post #287

Randell Mills GUT - Who can do the calculations?

I did* **look at the predictions here *in Figure 2 using paint.. 3.5 figure precision???????..

I could only find 1 figure precision

**1.5 MeV......... **+/- 0,2? **0.3 ? **0.4?

versus the experiment value for n-p

**1.293 332 05(48) MeV**

Perhaps THHuxley should consider what 300 kev is in Mev? and read arxiv correctly.

Or enquire from Stephan Durr whether he meant to write just 3 keV .. not 300 keV?

*"We performed lattice QCD**and QED with four nondegenerate *

*Wilson fermion flavors and computed **the
***neutron-proton mass-splitting **

*with an accuracy of 300 kilo-electron volts,*
