We all know that it is easy to get the beta mean and variance given the parameters α and β of the distribution (http://en.wikipedia.org/wiki/Beta_distribution). Can we do right the opposite? I.e. is there any way to go uniquely from mean and variance to the parameters of the beta?

Right what I need is a (maybe cheap) oscilloscope

Hello everyone, I am running a physics class next week where I want to show to high school children the power of piezoelectricity. I want to let them see with their own eyes that if a crystal is squeezed the differential potential between two opposite faces will change accordingly to the...

thanks Thanks it works! Not sure about the numerical stability but will keep an eye on it. Thanks again Cheers!

Does anybody know how to create a orthonormal basis, i.e. a matrix containing orthogonal vectors of norm 1, out of a given direction (normalised vector or versor) in a space with dimension N>3? With "out of a given direction", I mean that the resulting basis would have the first vector equal...
