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.”

Louvre Thieves Escaped With 30 Seconds to Spare, Probe Reveals

The thieves who stole priceless crown jewels from the Louvre in October escaped with just 30 seconds to spare due to avoidable security failures at the Paris museum, a damning investigation revealed on Wednesday.

The probe, ordered by the culture ministry after the embarrassing daylight heist, revealed that only one of two security cameras was working near the site where the thieves broke in on the morning of Sunday October 19, according to AFP.

Agents in the security headquarters also did not have enough screens to follow the images in real-time, while a lack of coordination meant police were initially sent to the wrong place once the alarm was raised, the report unveiled at the French Senate's Culture Commission, stated.

"It highlights an overall failure of the museum, as well as its supervisory authority, to address security issues," the head of the commission, Laurent Lafon, said at the start of a hearing.

One of the most startling revelations was that the robbers left only 30 seconds before police and private security guards arrived on the scene.

"Give or take 30 seconds, the Securitas (private security) guards or the police officers in a car could have prevented the thieves from escaping," the head of the investigation, Noel Corbin, told senators.

He said that measures such as a modern security camera system, more resistant glass in the door cut open with angle grinders, or better internal coordination could have prevented the loss of the crown jewels -- worth an estimated $102 million -- which have still not been found.

Security risks were highlighted in several reports commissioned by management of the Louvre, including a 2019 audit by the jewellery company Van Cleef & Arpels.

The evaluation said the balcony used by the thieves was a weak point in security and could be reached by using an extendable ladder -- exactly what transpired in the heist.

Corbin confirmed that under-fire Louvre boss Laurence des Cars had been unaware of the audit which was carried out by her predecessor, Jean-Luc Martinez.

"The recommendations were not acted on and they would have enabled us to avoid this robbery," Corbin said, adding that there had been a lack of coordination between the two state-appointed administrators.

Police believe they have arrested all four thieves, who escaped on powerful motorbikes, having carried out the heist in the Apollo Gallery in around 10 minutes in total.

The revelations on Wednesday are likely to pile more pressure on des Cars, who was already facing calls to resign.

Prince Mohammed bin Salman Royal Reserve Launches Live Turtle Tracking Program

In a milestone for marine conservation, Prince Mohammed bin Salman Royal Reserve has launched a live satellite tracking program for hawksbill and green turtles, including the first known tagging of a pre-nesting, egg-carrying green turtle in the Red Sea, SPA reported.

This data will fill a critical regional knowledge gap and drive unified, cross-border conservation strategies for these globally endangered species.

The team, led by Senior Marine Ecologist at Prince Mohammed bin Salman Royal Reserve Dr. Ahmed Mohammed and KAUST Beacon Development’s Senior Marine Megafauna Specialist Dr. Hector Barrios-Garrido, successfully in-water captured and tagged three critically endangered (IUCN) hawksbill turtles and seven green turtles. The tags transmit real-time movement data identifying foraging grounds, migratory corridors, and most crucially the nesting site of the egg-carrying green turtle, ensuring the appropriate protection and management is in place. The program continues the reserve’s long-term commitment to marine conservation, expanding its turtle nest monitoring and protection program in operation since 2023.

The reserve protects 4,000km² of Red Sea waters, 1.8% of the Kingdom’s marine area, and a coastline of 170km, the longest coastline under management by a single entity in the Kingdom. Linking NEOM and Red Sea Global, this forms an 800km corridor of protected Red Sea coastline. It is a refuge for five of the world’s seven turtle species and a breeding ground for green and hawksbill turtles. The reserve’s ranger teams monitor turtle activity both on shore and at sea, protecting nesting sites critical to natal homing, the biological instinct that drives turtles to return to the same beaches where they were born.

‘’Critically endangered hawksbill turtles face an extremely high risk of extinction in the wild within our lifetime. With fewer than 200 breeding-age females remaining in the Red Sea, their survival depends on closing vital knowledge gaps to enable their effective conservation,” said CEO of Prince Mohammed bin Salman Royal Reserve Andrew Zaloumis.

He added, “Hawksbill turtles hatching on the reserve’s protected beaches range across 438,000 km² of open sea bordered by eight MENA countries, before returning some three decades later to the same sandy beach to lay their eggs. Our satellite tagging and tracking program is a game-changer, providing the real-time data needed to identify their critical staging, foraging, and rookery areas across the Red Sea. The data will support national and regional conservation efforts to drive forward a much-needed unified ecosystem-wide turtle conservation management plan.’’

The reserve’s ongoing turtle conservation supports Saudi Arabia’s commitments under the UNEP Convention on Migratory Species and the IOSEA Marine Turtle Memorandum of Understanding by strengthening habitat protection and regional cooperation through scientific knowledge-sharing across the Red Sea.

Senior Marine Ecologist at the reserve Dr. Ahmed Mohammed stated, ‘’These state-of-the-art, lightweight tags are designed to operate for at least 12 months, providing continuous data that will enable detailed analysis of seasonal patterns, developmental habitats, and contribute valuable insights to regional and global sea turtle research. Additionally, depth sensors will reveal sea grass meadows, essential foraging grounds for green turtles and critical blue carbon sinks."

Despite the recent global reclassification of green turtles by the IUCN, regionally, they are still regarded as vulnerable and conservation dependent. All five marine turtle species resident in the Red Sea are listed under the Convention on Migratory Species (CMS), to which Saudi Arabia became a party in 1979. Turtles remain at risk from entanglement in fishing nets, habitat degradation, and illegal poaching. While these threats are absent within the reserve’s protected waters, ecosystem-wide management strategies that span political boundaries are necessary and the reserve continues to share data with the wider conservation and scientific community and partner with SHAMS on local and regional conservation strategies.

One of eight Royal Reserves, the 24,500 km² Prince Mohammed bin Salman Royal Reserve stretches from the lava plains of the Harrats to the deep Red Sea in the west, connecting NEOM, Red Sea Global, and AlUla. It is home to the Public Investment Fund's (PIF) Wadi Al Disah project and Red Sea Global’s Destination AMAALA.

The reserve encompasses 15 distinct ecosystems. At just 1% of the Kingdom’s terrestrial area and 1.8% of its marine area, it boasts over 50% of the Kingdom’s species, making it one of the most biodiverse protected areas in the Middle East.

Prince Mohammed bin Salman Royal Reserve is one of eight royal reserves established by royal decree and overseen by the Royal Reserves Council chaired by His Royal Highness Prince Mohammed bin Salman bin Abdulaziz Al Saud, Crown Prince and Prime Minister. The reserve’s program is integrated with Saudi Arabia’s wider sustainability and conservation programs, including the Saudi Green and Middle East Green Initiatives.
