Hey guys I have a few questions...
My book defines the Heisenberg uncertainty principle by
∆x∆Px >= aitch-bar
All other resources I have have it stated as
∆x∆Px >= aitch-bar/2. They mention that ∆Px and ∆x represent the rms values of independent measurements.
My book represents ∆x and ∆Px as the standard-deviation uncertanties right..
So say for instance you get a general question like x-cordinate of a proton is measured with uncertainty of 1.3mm. What is the xcomponent of velocity to the minimum percentage of uncertainty of 33%.
would you take ∆x as the standard deviation uncertanties or rms values ?
It seems like it varies from book to book but in general shouldn't this be the same? Say someone posed a question like this online, how would I know what to use?
