Isaac Newton's book auctioned for record-setting $3.7 million

A bound copy of Sir Isaac Newton's seminal book on mathematics and science was sold for $3.7 million, making it the most expensive printed scientific book ever sold at auction, according to Christie's, the auction house that handled the sale.

The book has a Latin title — "Philosophiae Naturalis Principia Mathematica," which translates to "Mathematical Principles of Natural Philosophy," but scholars often call it the Principia . After Newton (1642-1727) wrote the book, he gave it to the English astronomer Edmond Halley (1656-1742) for editing, and it was printed and sold in London more than 300 years ago, in 1687.

The book is a pivotal piece of science and history, and theoretical physicist Albert Einstein called it "perhaps the greatest intellectual stride that it has ever been granted to any man to make." Even so, Christie's expected the goat-skin-covered book to bring in between $1 million and $1.5 million, but the unnamed bidder bought it for nearly four times that value at $3,719,500.

The Principia famously elucidates Newton's three laws of motion , explaining how objects move under the influences of external forces. Physics students today still use the laws, which include:

-An object will remain in a state of inertia unless acted upon by force.

-The relationship between acceleration and applied force is force equals mass times acceleration (F=MA).

-For every action there is an equal and opposite reaction.

The crimson book measures about 9 inches by 7 inches and contains 252 leaves — some with woodcut diagrams — and a folding plate, according to Christie's. Only one other original leather-bound copy of Newton's Principia has been sold at auction in the past 47 years — a copy that was presented to King James II (1633-1701) and bought at Christie's New York for about $2.5 million in December 2013.

In the Principia's preface, Newton thanked Halley for encouraging him to write the book, saying, "Mr. Edmund Halley not only assisted me with his pains in correcting the press and taking care of the schemes, but it was his solicitations that its becoming public is owing; for when he had obtained of me my demonstrations of the figure of the celestial orbits , he continually pressed me to communicate the same to the Royal Society..." (translated by Andrew Motte). In a letter to the king in 1687, Halley wrote, "And I may be bold to say, that if ever Book was worthy the favourable acceptance of a Prince."

Halley also paid for the printing of the book; the Royal Society didn't have enough money at the time to cover the costs because it had just published another book, " De Historia Piscium " or "The History of Fishes" by John Ray and Francis Willughby. Luckily, Halley's contribution paid off: Newton's work was not seriously challenged until Einstein's theories of relativity and German theoretical physicist Max Planck's quantum theory were published in the 1900s. In fact, Newton's principles and methods are still used by scientists today.
