Asssumption: Uncertainties in each variable xi are independent.

\delta q = \sqrt{\left (\frac{\partial q}{\partial x_1}\delta x_1 \right)^2 + \left (\frac{\partial q}{\partial x_2}\delta x_2 \right)^2 + ...}

sum in quadrature

From Bradley's lab notebook:

\frac{e}{m}= (3.29\times10^6\frac{A\cdot m^2}{Wb}) \frac{V}{B^2 r^2}

What if the formula is really terrible?
