I have had my results for a long time: but I do not yet know how I am to arrive at them. - Carl Friedrich Gauss

Mathematics is the queen of the sciences

Life stands before me like an eternal spring with new and brilliant clothes.

The function just found cannot, it is true, express rigorously the probabilities of the errors: for since the possible errors are in all cases confined within certain limits, the probability of errors exceeding those limits ought always to be zero, while our formula always gives some value. However, this defect, which every analytical function must, from its nature, labor under, is of no importance in practice, because the value of our function decreases so rapidly... that it can safely be considered as vanishing. Besides, the nature of the subject never admits of assigning with absolute rigor the limits of error.
