by G. H. Hardy

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.

Orders of Infinity by Godfrey Harold Hardy is another ancient book that I don’t really feel comfortable touching. The copyright to this particular volume is from 1910. It is covered in tape and has multiple old tears and rips. Not to mention that it is practically a time capsule because of the little date stamps that the book still has. Remember when Libraries used to stamp things? If you live in an area without resources or a smaller area perhaps they still do stamp it, but I haven’t seen that for a few years now. Considering its condition, I am surprised the library even allowed me to take it out.

This book is remarkably short for talking about Infinity. Since the book is so delicate, I was not really able to ascertain exactly what it was about. When you talk about infinity, of course, there are different scales of infinity. There is an infinite amount of integers, and there are more rational numbers than there are integers. This is the sort of thing it seemed to be talking about although a single reading probably wasn’t enough to understand.
