Significance of commutation of operators? position and momentum

Click For Summary
SUMMARY

The discussion centers on the significance of the commutation of operators, specifically the position and momentum operators in quantum mechanics. It is established that these operators do not commute, which implies that simultaneous measurements of position and momentum cannot be made with arbitrary accuracy. The proof involves applying the mathematical definition of commuting operators, as outlined in the referenced Physics Forums thread.

PREREQUISITES

significance of commutation of operators?

how do u show that the position and momentum operators do not commute?
 
Physics news on Phys.org
If the operators commute, and the operators correspond to observables, then it is possible to make simultaneous measurements of the observables to arbitrary accuracy.

You show that two operators do or do not commute by applying the definition of commuting and doing the math. So start from the definition.
 
ive done some working out..
