The three-body problem, a formidable challenge in physics and mathematics, has just experienced a major breakthrough. An international team of mathematicians claims to have discovered no fewer than 12,000 new solutions to this more than 300-year-old puzzle.

The three-body problem involves predicting the motion of three celestial objects in gravitational interaction. If the movement of two objects in orbit (In celestial mechanics, an orbit is the trajectory that a body draws in space…) can be described by simple equations, the addition of a third object (Generally speaking , the word object (from the Latin objectum, 1361) designates an entity defined in…) considerably complicates the calculations. Isaac Newton (Isaac Newton (January 4, 1643 G – March 31, 1727 G, or December 25…) laid the foundations of this problem more than 300 years ago, and mathematicians have been searching for solutions ever since. Ivan Hristov, mathematician at the University of Sofia, Bulgaria, and his team used a supercomputer to find these new solutions. Unlike the simple orbit of our planet (A planet is a celestial body orbiting around the Sun or another star of…) around the sun (The Sun (Sol in Latin, Helios or Ήλιος in Greek) is the star…), the orbits in a three-body system can look like tangled spirals ((see talk page)). Objects move away and come together in a complex but predictable ballet.

These new solutions might be valuable for astronomers. Three-body systems are common in the Universe. However, the stability of these orbits remains to be verified. Juhan Frank, an astronomer at Louisiana State University, remains skeptical regarding their long-term stability.

According to Ivan Hristov, these solutions, stable or not, are of great theoretical interest. Their physical and astronomical relevance will be better known following more in-depth stability studies.

Ireland’s Ocean Research and Conservation Association (ORCA) and Huawei have released the latest key findings on protecting marine life in Ireland, discovered during their joint work on the Smart Whales Sounds project. The announcement took place during the OceanTech Summit at the Irish Baltimore Castle.

This press release includes multimedia. See the full statement here:

Shipping lanes in the southern Irish Celtic Sea are contributing significantly to noise pollution in the marine environment, the joint study found. Previous research has shown that ocean noise can affect several marine species, including seals, fish and even squid; and can threaten the survival of whales.

So far, the real-time multi-species detection system has shown that it has practical implications for marine conservation. It provides real-time notifications to vessels in areas where whales are present, thanks to its new acoustic data acquisition system. The system can potentially help with the planning of important marine infrastructure, such as offshore renewable energy facilities, to minimize the impact of noise on marine life during the construction phase.

Emer Keaveney, co-founder and chief executive of ORCA Ireland, said:

“Noise from vessels and other human activities in our waters can have an extremely harmful impact on marine life, such as whales and dolphins. Noise from ships, like the low hum of container ships, can mask whale calls, affect animal communication, and affect important life history strategies such as coordinated feeding or moving animals out of important habitats.

“Recent advances in technology provide greater opportunity to use these innovations for good and ensure our understanding of the natural world. To achieve this, we are using ModelArts [plataforma de desenvolvimento de IA] from Huawei and cloud storage, along with machine learning, to automate wildlife monitoring for marine conservation.”

Luis Neves, CEO of the Global Enabling Sustainability Initiative, commented:

“The work of capturing sound in the oceans and harnessing the power of AI and big data analytics to improve our understanding of marine ecology and its complex interactions with various threats is of paramount importance. This work not only facilitates broader public engagement, but also strengthens the effectiveness of conservation initiatives, ultimately contributing to the survival and well-being of marine species.

“At GeSI, we are proud to have our member Huawei take the lead and use its innovations and sophisticated AI/deep learning models to automatically detect and identify cetacean species and thus support dolphin and whale conservation.”

Luke McDonnell, head of PR at Huawei Ireland, said:

“Huawei believes that no one should be left behind in the digital world, and we have made it our mission to place digital inclusion at a prominent position in our business. In addition to environmental protection, we believe that digital technologies also play a fundamental role in many other areas. Digital technologies such as AI, cloud and 5G are being rapidly integrated and applied extensively across multiple industries. This is facilitating digital transformation and sustainable socioeconomic development, and bringing tangible benefits to society as a whole.”

Since March 2021, ORCA Ireland’s Smart Whale Sounds project has been taking place in partnership with Rainforest Connection (RFCx), with the support of Huawei Ireland through the TECH4ALL initiative, being the first real-time marine bioacoustic study in the country. Preliminary analysis has suggested that the south coast of Ireland is a “hub of activity” for cetaceans (whales, dolphins and porpoises). Cetaceans make up almost half of all animals within Ireland’s land and sea borders. Worldwide, marine mammals account for a third of the planet’s animals.

The Swiss Haute Horlogerie manufacturer Audemars Piguet is pleased to launch two new Royal Oak Offshore Automatic Chronographs in 43 mm

These two variations, which celebrate the 30th anniversary of the collection and join the references revealed at the start of the year, combine different materials including ceramic, titanium and gold. Available in two aesthetics and offering optimal ergonomics, these models are completed by a calfskin strap with textile effect and are powered by the Manufacture’s latest automatic chronograph movement, Caliber 4401.

Ergonomics and combination of materials

These two new 43 mm Royal Oak Offshore Automatic Chronograph models reinterpret the 26405CE model launched in 2020 in 44 mm. Combining materials such as ceramic, rose gold and titanium to offer a contrasting aesthetic and optimal readability, these new models emphasize ergonomics. Their design is distinguished in particular by large polished chamfers on the edges, while the bezel, the screw-down crown and the chronograph pushers trace a curved profile. The bezel is slightly curved from 6 to 12 o’clock, thus following the profile of the sapphire crystal.

Both models also incorporate ceramic elements resulting from a particularly demanding manufacturing process and benefiting from meticulous finishing techniques in order to respect the quality criteria of the Manufacture. The ceramic is composed of zirconium oxide (ZrO2) powder combined with a specific binder. Once the material is sintered at a temperature of around 1000°C, its color appears. The difficulty of this step consists of obtaining a perfectly homogeneous color. The various components are then pre-polished and pre-satined before being finished by hand, with the highlight being polished chamfers adjoining the satin-finished surfaces.

Deep blue or bright gray

The first model combines the black ceramic case with a blue ceramic bezel, pushers and crown for a deep contrast. The ceramic components decorated with the Manufacture’s emblematic hand finishes are contrasted by pusher guards and titanium studs. The timepiece is decorated with an intense blue smoked Mega Tapisserie dial which gradually turns black at its periphery. The dial is punctuated by three black counters arranged at 9 o’clock, 6 o’clock and 3 o’clock and illuminated by luminescent white gold stick indexes and hands, accentuating its readability.

The second reference sports a luminous aesthetic with an 18-carat pink gold case enhanced by a titanium bezel to which the bracelet studs and pusher protectors respond. The crown and pushers are designed in black ceramic, in harmony with the chronograph counters of the same color which stand out once morest the uniform gray Mega Tapisserie dial. The latter is punctuated with luminescent rose gold baton indexes hovering over matching hands.

A unique bracelet in the collection

These two 43 mm Royal Oak Offshore Automatic Chronographs feature the strap interchangeability system introduced in 2021 by the Manufacture and their textile-effect calfskin straps add an additional touch of elegance and refinement.

Matching the color of the dial, these bracelets, introduced for the first time in the collection at the start of 2023, are lined with black stitching. In both cases, they are accompanied by a second black rubber strap, offering a sportier alternative.

A fully integrated chronograph

At the heart of these Royal Oak Offshore models beats Caliber 4401, the Manufacture’s latest integrated automatic chronograph movement equipped with a column wheel and flyback function.

Unlike simple chronographs, this function allows you to reset and restart the chronograph with a single press of the pusher. The column wheel works in symbiosis with the vertical clutch. When started or stopped, the seconds hand responds immediately, smoothly. What’s more, the pushers are designed to provide gentle pressure. When reset to zero, the hands of each counter all instantly return to vertical thanks to a patented process. The movement is decorated with refined finishes such as Côtes de Genève, perlage, sunburst, circular satin-finishing and polished chamfers – visible through the sapphire caseback.

By combining various materials and meticulous finishes, these two 43 mm Royal Oak Offshore Automatic Chronograph models bring a contemporary and elegant touch to the collection.
