Christie's to Sell Isaac Newton's Notes for Greatest Work

Handwritten notes that show one of history’s greatest scientific minds in action are going up for auction in London.

Pages containing Isaac Newton’s jotted revisions to his masterwork, the “Principia,” are expected to sell next month for between 600,000 pounds and 900,000 pounds ($850,000 and $1.3 million), auctioneer Christie’s said Tuesday.

Published in 1687, Newton’s “Philosophiae naturalis principia mathematica” — “Mathematical Principles of Natural Philosophy” — set out the laws of gravitation and motion and is considered a scientific watershed. A first edition of the book sold at auction for $3.7 million in 2016.

Thomas Venning, head of books and manuscripts at Christie’s in London, said the book “reinvented our understanding of the universe.”

The page and a half of notes for a planned second edition includes comments and diagrams by Scottish mathematician and astronomer David Gregory. The two scientists met and corresponded while Newton worked on revising the “Principia” in the 1690s.

Venning said that when he was working on the revisions, Newton was “fizzing with the energy of one of the greatest minds the world has ever seen.”

“And we can see that at work, the speed with which he’s writing, the ferment of ideas coming out from his pen,” he said.

Keith Moore, head librarian at the Royal Society — the scientists’ club where Newton was president in the 18th century — said Gregory “kept up a written dialogue with Newton. He met Newton and that partnership, almost, between the two of them, resulted in refining Newton’s thinking.”

Newton eventually gave up on the revisions, but ultimately produced a new edition in 1713.

The document will go under the hammer at Christie’s in London on July 8.

“What a collector in the autograph world is looking for is the greatest minds in history, talking about their greatest achievements,” Venning said. “It’s very, very rare to have that combination. And that’s what you have in this particular manuscript.”

Storm Leonardo continued to batter the Iberian Peninsula on Friday, bringing floods and putting rivers at risk of bursting their banks while thousands of people were evacuated from their homes in Spain and Portugal.

In southern Spain's Andalusia region, some 7,000 people have had to leave their homes due to successive storms.

Among them were around 1,500 people ordered to evacuate the mountain village of Grazalema, where Andalusia's regional leader Juan Manuel Moreno warned that aquifers were "full to the brim with water,” and at risk of collapsing.

“It's raining on already saturated ground. The land is unable to drain," Moreno said. “We urge extreme caution. This is not over.”

Spanish police said Friday they had found a body located 1,000 meters (about 0.6 miles) away from where a woman had disappeared Wednesday after she fell into a river in Malaga province while trying to rescue her dog. Police said they had not yet identified the body, but believed it belonged to the 45-year-old woman.

Another storm front, Marta, was expected to arrive Saturday, with Spain's weather agency AEMET saying it would bring even more rain and heavy winds, including to areas already drenched by Storm Leonardo.

Marta is expected to affect Portugal, too.

Of particular concern was southern Spain's Guadalquivir River, which flows through Córdoba and Seville and eventually into the Atlantic Ocean, and whose water levels have dramatically risen in recent days.

Additional rain Saturday could leave many more homes at risk in Córdoba, local authorities warned.

In Portugal, parts of Alcacer do Sal were submerged after the Sado River overflowed, forcing residents to leave the city located 90 kilometers (about 56 miles) south of Lisbon.

Alerts were issued also for regions near the Tagus River due to rising water levels.

A separate storm in late January left a trail of destruction in Portugal, killing several people, according to Portuguese authorities.

Denmark authorities halted public transport, closed schools and cancelled flights on Friday as heavy snowfall blanketed much of the country.

The Nordic country's meteorological institute DMI warned that heavy snow would likely continue until Friday evening in the east, where the capital Copenhagen is located.

Police said people should avoid going outdoors unless necessary and stay indoors in the capital and the surrounding region.

Copenhagen's airport cancelled flights to Paris and Berlin and warned of "delay and cancellation risks because of snowy conditions." Many schools were closed.

In the second-largest city of Aarhus, bus services were cancelled.
