    Mass Ratio
AI Thread Summary
The proton:electron mass ratio remains unresolved, with no theoretical framework able to predict its value. Current understanding indicates that the masses of fundamental particles, including protons and electrons, are not explained by existing theories. This topic continues to be a significant challenge in physics, often cited as a potential Nobel Prize problem. Despite ongoing research, there have been no breakthroughs reported. The quest for a theoretical explanation of particle masses continues.

Reading my old copy (3rd edition) of H&R's Fundamentals of Physics and it states that no theory can predict the value of the proton:electron mass ratio to date, and that it's a "sure-fire" Nobel Prize problem. Has this been resolved yet? Can't find anything on the web.

Thanks in advance.

No it hasn't. None of the masses of any of the fundamental particles are currently explained by theory.

Thread 'Reflections at the source point of a transmission line.'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
