How a first edition of Principia with Isaac Newton's notes got to Sydney
Title page of The Principia, 1687.聽
First published in 1687, Principia (Philosophiae Naturalis Principia Mathematica) is one of the most important books on natural philosophy in which Newton establishes the modern science of dynamics and outlines his three laws of motion.
While the original print run is estimated at between 250 and 400 copies, there are only 189 surviving first editions in the world and only four with annotations by the English mathematician himself. Of these four copies, the Sydney copy of Principia is the only one in the Southern Hemisphere and is held in the at the University of Sydney library.
This extremely rare copy of the seminal text is believed to be a personal copy of Newton鈥檚, which he and his assistant Roger Cotes sent to other mathematicians to eliminate any errors before the second edition was published.
"It clearly shows how Newton鈥檚 ideas were received by his contemporaries," said Julie Sommerfeldt, Manager of Rare Books & Special Collections at the .
Scottish mathematician John Craig is thought to have authored the corrections which feature at the front of the book along with other annotations throughout. Further corrections can be seen in this copy, written by Roger Coates and Newton himself.
Corrections on Sydney's copy of Principia
"You could liken it to the 17th Century version of the peer-review process. Handling the physical item itself is a special experience; you can see the words inked on the page and know that they came from Newton鈥檚 own hand."
How significant is the book?
Explaining the significance of Principia for the field of mathematics and science in general, calls the work "completely revolutionary".

"The publication was really the first time we saw a physical law that was true everywhere. Without this work, for instance, Maxwell鈥檚 equations governing electricity or Fourier series equations on heat, would not have been possible," said Professor Williamson, Director of the at the University.
"Isaac Newtown totally rewrote the rule book in terms of the separation of what happens on Earth and what happens in space. Before Newton, European science considered there was a fundamental divide between 鈥楬eaven and Earth."
"Through Principia, Newtown established the fundamental fact that the same laws apply here on Earth as those in the heavens."
Professor Williamson last year was , the world鈥檚 oldest scientific academy and publisher of Principia. Newton was President of the Royal Society from 1703 to 1727.
How Principia almost didn鈥檛 go to print
Halley鈥檚 ode to Sir Isaac Newton.
As Newton was finalising his work the Royal Society was printing a book called聽The History of Fishes.
"This book is quite lavishly illustrated and unfortunately the Society didn鈥檛 have enough budget to publish聽Principia,鈥� Ms Sommerfeldt said.
"So, Edmond Halley 鈥� the English astronomer of Halley鈥檚 Comet fame and also a Clerk of the Society 鈥� stepped in to personally fund publication of the book."

From Kent to Sydney: History of the book
After Newton, the next known owners were the family of Sir Demetrius James of Ightham Court in Kent, United Kingdom. While the date of acquisition remains a mystery, it鈥檚 likely to be one of his descendants who was the next owner.

The book remained in an old clock tower in the James estate in Kent for about 140 years before it travelled to Australia in the hands of Harry Constantine Adolphus Elderton in 1854.
A distant relative of the James family, he inherited eight chests of books from the estate.聽
笔谤颈苍肠颈辫颈补听remained hidden in the chests until the Hon Arthur Bruce Smith stumbled across the book, purchasing it sight unseen after seeing it on a list of books for sale shortly after the chests arrived in Australia.
The future of Principia at Sydney
Ms Sommerfeldt described the condition of the book as excellent: "With careful handling, this copy will hopefully withstand centuries to come so that future generations can enjoy and study it."
The University of Sydney copy of聽Principia聽has been digitised and is available online alongside other digital resources聽.
Members of the public, students and staff can access the book at the University of Sydney Fisher Library聽.
