Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
Alfred Arthur Robb (1873-1936) was a British mathematician known for his contributions to geometry and mathematical physics. He was a professor at the University of St Andrews and authored several influential works in the field of mathematics. Robb's research focused on the geometric interpretation of physical laws, particularly in the context of relativity theory and spacetime geometry.
