""On The Algebraical And Numerical Theory Of Errors Of Observations: And The Combination Of Observations"" is a book written by George Biddell Airy and published in 1875. The book discusses the theory of errors in scientific observations, including how to calculate and combine these errors. It provides a detailed explanation of the algebraic and numerical methods used to analyze and interpret observations, with a focus on astronomy and geodesy. Airy's work was influential in the development of modern statistical methods and remains an important reference for scientists and mathematicians today. The book is written in a technical style and assumes a basic understanding of algebra and calculus.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
