    Simple overestimate of slope uncertainty in regression

    Interesting point about the 1 standard deviation "problem", I have not heard about this before and am surprised. Care to reference? I think we are maybe in some agreement on teaching these teenagers about uncertainties. My suggestion is indeed an attempt at a "reasonable estimate" of error...

    Simple overestimate of slope uncertainty in regression

    Good idea! Thanks for the suggestion, might be a fun exercise.

    Simple overestimate of slope uncertainty in regression

    hehe, I am certainly a fool, no doubt about that! But I don't think it is out of the question to let them think about stuff like this. Students in my country range between 15-20 years of age from beginning-end in high school. My proposed estimate should work even though they haven't yet had...

    Simple overestimate of slope uncertainty in regression

    Hi all, I am a science educator in high school. I have been thinking about how to make a simple estimate that 1st and maybe 2nd year students can follow for the propagation of error to the uncertainty of the slope in linear regression. The problem is typically that they make some measurements...

    A Zeeman energy with an effective mass

    Hi all, Say we have a model in a solid state system where we have an effective mass, \begin{equation}m^*,\end{equation}some fraction of the free electron mass. Now we apply an external magnetic field. Then the Zeeman energy splitting should be: \begin{equation} E_{Zeeman}=\pm 1/2 g \mu_B B...
