comment Multivariate Analysis: how to start
@KyleKanos Oh, you are right, I wasn't precise. I'd like to have something about Programming and Multivariate Analysis because I have to use it with ROOT...

comment Doppler cooling limit vs recoil limit
You have said "consider the total heating and cooling power of the beam, at intensities far below saturation. The total heating power is roughly one photon's kinetic energy per natural lifetime,[..]" and I'm asking in which way the light can heat the atoms since that when atom absorbs a photon it is cooled...

comment Doppler cooling limit vs recoil limit
I was looking for an explanation about causes of Doppler and recoil limit and I have found your answer. It is very interesting and I'm going to think about it.. but could you explain me the causes of heating due to the light? Many thanks!

@zeldredge I can't understand in which way is possible to obtain the momentum distribution having the distribution of fluorescence... can you explain me? Many thanks again!

comment How to measure temperature of a laser cooled sample at picoKelvin temperatures?
So many thanks for sharing your knowledge and for the paper that you have suggested to me. I'll read it carefully, because I haven't undestood your sentence: "Number of particles was measured using optical absorption".. the only way that I know is to use Lambert-Beer Law...

@zeldredge A lot of thanks for your comment, it's very interesting! Could you expand it a little so I can undestand it better? Many thanks again

@JohnRennie I'm not sure to have correctly understood. Do you mean that it is used the Doppler FWHM? (en.wikipedia.org/wiki/Doppler_broadening)

@ConstantineBlack it wasn't a lesson... it was a.. small talk. He said "Can anyone answer to this question?"
