Accuracy of Relativity vs Quantum Mechanics Measurement

[windy miller]

Just for a bit of fun, which theory , relativity or quantum mechanics has the most accurate ( i.e to how many decimal places confirmation between theory and experiment) measurement ever made?

 

[Dale]

relativity or quantum mechanics

Modern QM is built on relativity, so there is no either-or comparison possible.

Modern QM is built on relativity, so there is no either-or comparison possible.

But here are certain measurement that are considered to be precision test of either theory, time dilation in atomic clocks or the anomalous magnetic moment of an electron. This question really is just for a bit of fun.

 

[Herman Trivilino]

The magnetic moment of an electron cannot be understood without relativistic quantum theory.

The operation of an atomic clock cannot be understood without relativistic quantum theory.

Relativistic quantum theory makes predictions that match experimental results to a greater extent than any other theory ever created.
