Amateurs proved prominent during the opening round of the Mitsubishi Electric FA Golf Open in Suzhou, East China’s Jiangsu Province, on Thursday. Hong Kong SAR’s Alexander Yang and Chongqing’s Zhou Yanhan each carded a six-under 66 to share the early lead with veteran Yuan Tian.

Chinese players Jin Daxing, Huang Zijie, Luo Xuewen, Liu Enhua, Sun Yan, and Wu Di were a shot off the pace at the event taking place at Suzhou Taihu International Golf Club.

Zhou, the 15-year-old son of Tour player Zhou Xunshu, turned it on late in his round when he carded five birdies over the last seven holes to grab a share of the lead.

“I didn’t hit it solid for the whole round, but my putter was hot. I made four putts from 15 feet. I missed some putts on the front nine, but I kept my patience,” said the teenager who won last year’s Chongqing Open against a pro field.

Yang, who earlier this year became the first Hong Kong man to play in the US Open, started his round on the back nine, carding three birdies and two bogeys to make the turn at one-under.

“Today was a great start. I think I did most things pretty well,” said Yang, who is currently on leave from Stanford University. “I’m still getting used to the grass here. It’s definitely unique and different from what I’m accustomed to in the US. I made a couple of bogeys and mistakes here and there but otherwise I played really solid.”

Yuan, a 41-year-old veteran who continues to chase his first China Tour win after 18 years as a pro, carded his best round of the year on the strength of seven birdies and a lone bogey in his early morning start that began on the back nine.

The Shanghai Mingyuan Art Museum recently unveiled its inaugural exhibition, Delight in the Invisible - An "Abstract" Narrative of Momentary, to mark the opening of the new gallery. 

The exhibition is a further advancement of the "Perception Art" concept of the 2019 Shanghai Mingyuan Art Museum.

"Delight in the Invisible" is a specific issue deeply explored in the "Perception Art" concept, which has a very thoughtful relationship with art history. The intention of the term is to discuss art issues, and to examine the development of literati painting and contemporary art with "Delight in the Invisible" as the topic.

The exhibition explores the new development possibilities of contemporary Chinese art now or in the future through the works of 27 representative artists.

The Shanghai Mingyuan Art Museum was officially established in 2004. Covering an area of over 2,000 square meters, it is the first private non-profit art museum established in Shanghai and has been free to the public since its opening.

The museum adheres to the concept of development and dissemination of contemporary Chinese art. 

Through themed exhibitions, academic exchanges, art collection, public education and other activities, it provides an open platform for the public to display and exchange art, and also sets up a corresponding dialogue mechanism for the field of art research at home and abroad.

One Chinese national has been killed and another injured, the Chinese Embassy in Thailand confirmed late Tuesday night after a shooting incident which left two dead and five injured at one of the most popular shopping malls in Thailand on Tuesday afternoon.

The embassy said it activated its emergency response mechanism to verify the situation in the wake of the incident and has confirmed the identities of the victims, adding that the injured individual has received medical treatment and remained in stable condition.

Thai Prime Minister Srettha Thavisin visited the injured Chinese national at the hospital, the embassy confirmed. Both the prime minister and Parnpree Bahiddha-Nukara, the deputy prime minister and minister of foreign affairs, respectively made phone calls to Chinese Ambassador to Thailand Han Zhiqiang to express their condolences to the deceased Chinese national on behalf of the Thai government.

They vowed to quickly deal with the case to ensure a safe and reliable environment for the Chinese nationals in Thailand.

A chaotic scene unfolded at the Siam Paragon mall in Bangkok, Thailand on Tuesday afternoon as gunshots rang out near an upscale retail area. According to National Police Chief Torsak Sukvimol, at least two people were killed and five others injured in the shooting and the police has arrested the suspect, a 14 years old suffering from a mental illness.

On Wednesday, Thai Police filed five charges against the suspect, including intentional homicide, commission of homicide, unlawful possession of a firearm, carrying a firearm into a public place without authorization, and discharging a firearm in a public place without authorization.

Thai police said the other victim was from Myanmar and the four injured included a Laotian and three Thai people.

According to local media, the 34-year-old Chinese female surnamed Zhao was shot dead when walking through the Siam Paragon building. A Chinese netizen named “Chloe Wan” wrote on China’s Twitter-like social media platform Sina Weibo that the shooter began shooting at the female toilet on the second floor, killing her acquaintance and injuring her mother.

“Aunt Zhao is a nice person. We three families, including Zhao’s husband and twin daughters, travelled to Thailand together. I didn’t know how she was hurt. I only saw her fainted on the ground with blood flowing out of her mouth. Her five-year-old children didn’t know about this. They were staying with their dad,” wrote the netizen, as quoted by Shangyou News.

The hashtags including “A Chinese visitor shot dead in Siam Paragon” had received more than 290 million views and comments on Sina Weibo as of Wednesday morning, and some netizens have expressed safety concerns on travelling to Thailand.

In September, the Thai government announced a temporary tourist visa exemption scheme for Chinese and Kazakh travelers to boost tourism.

In the face of an escalating climate change threat, the Belt and Road Initiative (BRI) actively champions the spirit of green and low-carbon development, advocating for a sustainable future. 

As the recent BRI white paper released by China's State Council points out, the BRI embraces the global trend of green and low-carbon development, emphasizes respect for and protection of nature, and respects the right of all parties to pursue sustainable and eco-friendly growth.

Despite vicious campaigns launched by certain Western media outlets to smear the BRI as causing environmental damage in other countries, analysts noted that the real fact is that by making use of the expertise in renewable energy, energy conservation, environmental protection, and clean energy production, and employing Chinese technology, products, and experience, China actively promotes BRI cooperation in green development.

During visits by Global Times reporters to various BRI project sites worldwide, it became evident that Chinese enterprises prioritize environmental conservation measures when conducting operations abroad. Meanwhile, there is an increasing uptake of Chinese energy products in Belt and Road countries transported by rail and air, effectively harnessing renewable resources like wind and solar energy.

Taking the cooperation between China and Fiji as an example, in 2014, China and Fiji established the South-South cooperation to address climate change. In May 2022, the two countries signed a bilateral MOU on the Provision of Goods under the South-South Cooperation for Addressing Climate Change. 

Chinese Ambassador to Fiji Zhou Jian told the Global Times that China and Fiji are both victims of climate change, as well as allies in addressing climate change. 

Analysts pointed out that the cooperation between China and Fiji is a shining example of the green BRI. The Belt and Road Initiative Action Plan not only laid out the overarching vision and framework of the BRI but also underscored the paramount significance of environmental preservation and sustainability within BRI projects.

Furthermore, China, in conjunction with BRI participant nations, has established comprehensive frameworks for the implementation of Environmental Impact Assessment (EIA) Guidelines for BRI projects. These guidelines have proven instrumental in ensuring that environmental considerations are integrated into the planning and execution of projects.

China has also extended its commitment to environmentally sustainable BRI initiatives through various international agreements and partnerships. This includes the signing of an MOU with the United Nations Environment Programme, aimed at fostering a green Belt and Road from 2017 to 2022. Additionally, China has entered into environmental cooperation accords with over 30 countries and international organizations. Furthermore, in collaboration with various nations, China launched the Initiative for Belt and Road Partnership on Green Development. It has also played a pivotal role in establishing the BRI International Green Development Coalition, boasting more than 150 partners from over 40 countries, the Xinhua News Agency reported.

China successfully carried out a trial test on the main engine of the Long March-10, a new carrier rocket designed for manned moon landing missions, on Saturday, as the country actively makes progress on the road to realizing its goal of landing taikonauts on the moon by the year 2030.

The test assessed all the requirements for the engine, and provided strong support for the solidification for its technical state, the establishment of the technical baseline of the product and improving reliability, the Global Times learned from the China Aerospace Science and Technology Corporation (CASC) 6th Academy on Sunday.

The engine used in the test employs advanced liquid oxygen as fuel and can reach a thrust of 130 tons. It is an updated version of China's strongest active rocket engine, which has a thrust of 120 tons and is used in rockets including the Long March-5.

Although the thrust of the engine has only improved by 10 tons, the first stage of the Long March-10 will reportedly carry 21 engines. This will add another 210 tons of the thrust in total, Wang Yanan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Sunday.

Zhou Xianqi, a researcher from the CASC, told the Global Times that "the engine has met all the requirements in the Saturday test." He noted that the engine's startup, shutdown and running stability under high and low conditions have been tested, and all relevant parameters have been obtained.

During the development of the engine, many new materials, new processes and new technologies were applied. Researchers have overcome a number of key technical problems such as the sequence of the engine's start-up and shutdown, continuously changing the engine's thrust at scale, in addition to the engine's long life and improved reliability, laying a solid foundation for the engine's future development, the Global Times learned.

"In the second half of this year, we will conduct several high-altitude simulation tests to determine the relevant performance and parameters of this engine," Zhou added.

The new carrier rocket has mainly been developed for the purpose of sending spacecraft and moon landers into the Earth-moon transfer orbit, Rong Yi, a rocket expert with the CASC China Academy of Launch Vehicle Technology, was quoted as saying by the Xinhua News Agency on Saturday.

The rocket uses liquid hydrogen, liquid oxygen and kerosene as propellants. It has a total length of about 92 meters, a takeoff weight of about 2,187 tons, a takeoff thrust of about 2,678 tons, and a carrying capacity of no less than 27 tons for the Earth-moon transfer orbit, according to Xinhua.

A non-booster configuration of the new rocket is capable of conducting missions for transporting taikonauts and cargo to the space station. Its total length is about 67 meters, the takeoff weight is about 740 tons, the takeoff thrust is about 892 tons, and the low-Earth orbit carrying capacity is no less than 14 tons.

The Long March-10 serves as strategic pillar for China's aim to land taikonauts on the moon before 2030. Preparations for the maiden flight are expected to start in 2027, Rong told Xinhua.

Experts are confident that China will be able to accomplish a manned moon landing before 2030 if the Long March-10 can carry out its maiden flight in 2027, as many parts of the carrier rocket such as the engine, core module and other technical structures are upgrades from those in the Long March-5 series of carrier rockets and so have already been fully tested, according to Wang.

China revealed on July 12 that its primary plan is to carry out a manned moon landing before 2030. To achieve this goal, the country will attempt to use two launch vehicles to send a moon surface lander and manned spacecraft into lunar orbit, which will then rendezvous and dock with each other. Following this maneuver, taikonauts onboard the manned spacecraft will enter the lander.

Apart from the progress with the high-thrust engine and the Long March-10 carrier rocket, China is also actively developing spacecraft and lunar landers for the manned moon landing.

China's new-generation of manned spacecraft successfully entered orbit by Long March-5B carrier rocket and returned to Earth during tests in May 2020. Based on the new spacecraft, China is also advancing development of near-Earth spacecraft designed to accommodate four to seven crew members, building a future for space tourism.

China's lunar lander weighs about 26 tons and consists of a lunar landing module and propelling module. It can bring taikonauts down from lunar orbit to land on the moon and send them back to lunar orbit. The lunar lander is also able to conduct autonomous flight. The lunar lander will also carry scientific payloads for exploration focusing on lunar geology and lunar physics, observation, space life sciences, as well as deep drilling on the lunar surface and utilization of lunar resources, according to Xinhua.

In addition to the lunar rover, China also plans to develop a lunar mobile laboratory with large-scale mobile capability, which can realize long-term unmanned autonomous activities on the lunar surface and support taikonauts for short time stays, Xinhua said.

A new, extremely black material can turn water into steam using only sunlight, without the need to bring the water to a boil. Made of gold nanoparticles tens of billionths of a meter wide affixed to a scaffold pocked with tiny channels, or “nanopores,” the material is a deep black color because it reflects very little visible light. It is 99 percent efficient at absorbing light in the visible spectrum and parts of the infrared spectrum, researchers report April 8 in Science Advances.

Thanks to its highly porous structure, the material floats on the surface of water, allowing it to soak up the sun’s rays. When light of a certain wavelength hits a gold nanoparticle inside one of the nanopores, it stirs up the electrons on the surface, sloshing them back in forth in an oscillation known as a plasmon. These plasmons produce localized, intense heating, which vaporizes the water nearby.
The wavelength of light that excites a plasmon depends on the size of the nanoparticle. So in order to take advantage of as much of the sun’s output as possible, the group interspersed a variety of sizes of gold nanoparticles in the pores, which could therefore absorb a range of wavelengths.
It’s not the first time scientists have produced steam with plasmonic materials, but the new material improves the efficiency of the process, converting up to 90 percent of the light’s energy into steam, says materials scientist Jia Zhu of Nanjing University in China, a leader of the research group.

“They have really come out with a very intriguing solution,” says mechanical engineer Nicholas Fang of MIT, who was not involved in the research. The efficiency isn’t quite as high as scientists have achieved with certain other types of materials, like carbon nanotubes, Fang says. But the new material should be cheaper to manufacture.

Efficient steam generation could be useful for desalination, producing freshwater from salty water, says Zhu. Other potential applications range from sterilization to running steam engines. “Steam can be used for many other things,” he says. “It is a very useful form of energy.”

Animal-hair cords dating to the late 1700s contain a writing system that might generate insights into how the Inca communicated, a new study suggests.

Researchers have long wondered whether some twisted and knotted cords from the Inca Empire, which ran from 1400 to 1532, represent a kind of writing about events and people. Many scholars suspect that these textile artifacts, known as khipus, mainly recorded decimal numbers in an accounting system. Yet Spanish colonial documents say that some Inca khipus contained messages that runners carried to various destinations.
Now a new twist in this knotty mystery comes from two late 18th century khipus stored in a wooden box at San Juan de Collata, a Peruvian village located high in the Andes Mountains. A total of 95 cord combinations of different colors, animal fibers and ply directions, identified among hundreds of hanging cords on these khipus, signify specific syllables, reports Sabine Hyland. Hyland, a social anthropologist at the University of St. Andrews in Scotland, describes the khipus online April 19 in Current Anthropology.

Her findings support a story told by Collata villagers that the khipus are sacred writings of two local chiefs concerning a late 18th century rebellion against Spanish authorities.

The Collata khipus display intriguing similarities to Inca khipus, including hanging cords with nearly the same proportions of two basic ply directions, Hyland says. A better understanding of Central Andean khipus from the 1700s through the 1900s will permit a reevaluation of the earlier Inca twisted cords, she suggests.

Each Collata khipu, like surviving Inca examples, consists of a horizontal cord from which a series of cords hang. One Collata specimen contains 288 hanging cords separated into nine groups by cloth ribbons tied at intervals along the top cord. The other khipu features 199 hanging cords divided by ribbons into four groups. Knots appear only at cord ends to prevent unraveling. In contrast, proposed accounting khipus contain many knots denoting numbers.

Collata khipus’ initial hanging cords are made of bundles of colored animal hairs that represent the message’s subject matter, Hyland proposes. One khipu starts with a tuft of bright red deer hair, followed by a woven, cone-shaped bundle with metallic-colored thread. The second khipu commences with a woven, tube-shaped bundle of multicolored alpaca hair atop the remains of a red tassel.
“The Collata khipus are completely unlike accounting khipus that I have been studying for over a decade,” Hyland says. Central Andean khipus generally viewed as accounting devices were often made of cotton, and they contain two main colors, between 15 and 39 cord combinations and repetitive knot sequences.

Hyland makes an “excellent case” that these cords represent syllables and probably words as well, says anthropological archaeologist Penelope Dransart of the University of Wales Trinity Saint David in Lampeter.

So far, Hyland has translated the final three cords on one khipu as the word Alluka, the name of a family lineage in Collata. She first talked to villagers and identified the lineage chief that they claimed wrote one of the khipus. Hyland then assigned the three syllables in Alluka to the trio of ending cords, assuming that the sender’s name would appear either there or at the beginning of the message. That enabled her to decipher the final cords on the second khipu as Yakapar, the name of a family lineage in a neighboring village. Heads of these lineages wrote the corded messages, Hyland suspects.

She has not yet deciphered other cords on the two khipus.

Hyland’s insights into 18th century khipus are “profoundly significant,” but won’t help to decipher Inca twisted and knotted cords, predicts Harvard University archaeologist Gary Urton. Collata villagers probably invented a phonetic form of khipu communication after the Inca civilization’s demise, when they were exposed to Spaniards’ alphabetic writing, Urton says. Inca khipus show no signs of cord combinations that corresponded to particular speech sounds, he asserts.

Thanks to the new discoveries, though, “we have hope that at least some khipus might be understood,” says archaeologist Jeffrey Splitstoser of George Washington University in Washington, D.C. Before Hyland’s report, Splitstoser thought it likely that colored threads on khipus had arbitrary meanings assigned by their makers, making them indecipherable. He studies khipus from the Wari empire, which flourished in the Peruvian Andes from around 600 to 1000 (SN: 5/10/03, p. 302).

Officials at several museums with khipu collections have classified as forgeries a few animal-hair specimens that resemble the Collata khipus, Hyland says. Those alleged fakes deserve a closer look for signs of writing, she contends.

Plate tectonics may have gotten a pretty early start in Earth’s history. Most estimates put the onset of when the large plates that make up the planet’s outer crust began shifting at around 3 billion years ago. But a new study in the Sept. 22 Science that analyzes titanium in continental rocks asserts that plate tectonics began 500 million years earlier.

Nicolas Greber, now at the University of Geneva, and colleagues suggest that previous studies got it wrong because researchers relied on chemical analyses of silicon dioxide in shales, sedimentary rocks that bear the detritus of a variety of continental rocks. These rocks’ silicon dioxide composition can give researchers an idea of when continental rocks began to diverge in makeup from oceanic rocks as a result of plate tectonics.

But weathering can wreak havoc on the chemical makeup of shales. To get around that problem, Greber’s team turned to a new tool: the ratios of two titanium isotopes, forms of the same element that have different masses. The proportion of titanium isotopes in the rocks is a useful stand-in for the difference in silicon dioxide concentration between continental and oceanic rocks, and isn’t so easily altered by weathering. Those data helped the team estimate that continental rocks — and therefore plate tectonics — were already going strong by 3.5 billion years ago.

When you think about it, it shouldn’t be surprising that there’s more than one way to explain quantum mechanics. Quantum math is notorious for incorporating multiple possibilities for the outcomes of measurements. So you shouldn’t expect physicists to stick to only one explanation for what that math means. And in fact, sometimes it seems like researchers have proposed more “interpretations” of this math than Katy Perry has followers on Twitter.

So it would seem that the world needs more quantum interpretations like it needs more Category 5 hurricanes. But until some single interpretation comes along that makes everybody happy (and that’s about as likely as the Cleveland Browns winning the Super Bowl), yet more interpretations will emerge. One of the latest appeared recently (September 13) online at arXiv.org, the site where physicists send their papers to ripen before actual publication. You might say papers on the arXiv are like “potential publications,” which someday might become “actual” if a journal prints them.

And that, in a nutshell, is pretty much the same as the logic underlying the new interpretation of quantum physics. In the new paper, three scientists argue that including “potential” things on the list of “real” things can avoid the counterintuitive conundrums that quantum physics poses. It is perhaps less of a full-blown interpretation than a new philosophical framework for contemplating those quantum mysteries. At its root, the new idea holds that the common conception of “reality” is too limited. By expanding the definition of reality, the quantum’s mysteries disappear. In particular, “real” should not be restricted to “actual” objects or events in spacetime. Reality ought also be assigned to certain possibilities, or “potential” realities, that have not yet become “actual.” These potential realities do not exist in spacetime, but nevertheless are “ontological” — that is, real components of existence.

“This new ontological picture requires that we expand our concept of ‘what is real’ to include an extraspatiotemporal domain of quantum possibility,” write Ruth Kastner, Stuart Kauffman and Michael Epperson.

Considering potential things to be real is not exactly a new idea, as it was a central aspect of the philosophy of Aristotle, 24 centuries ago. An acorn has the potential to become a tree; a tree has the potential to become a wooden table. Even applying this idea to quantum physics isn’t new. Werner Heisenberg, the quantum pioneer famous for his uncertainty principle, considered his quantum math to describe potential outcomes of measurements of which one would become the actual result. The quantum concept of a “probability wave,” describing the likelihood of different possible outcomes of a measurement, was a quantitative version of Aristotle’s potential, Heisenberg wrote in his well-known 1958 book Physics and Philosophy. “It introduced something standing in the middle between the idea of an event and the actual event, a strange kind of physical reality just in the middle between possibility and reality.”

In their paper, titled “Taking Heisenberg’s Potentia Seriously,” Kastner and colleagues elaborate on this idea, drawing a parallel to the philosophy of René Descartes. Descartes, in the 17th century, proposed a strict division between material and mental “substance.” Material stuff (res extensa, or extended things) existed entirely independently of mental reality (res cogitans, things that think) except in the brain’s pineal gland. There res cogitans could influence the body. Modern science has, of course, rejected res cogitans: The material world is all that reality requires. Mental activity is the outcome of material processes, such as electrical impulses and biochemical interactions.

Kastner and colleagues also reject Descartes’ res cogitans. But they think reality should not be restricted to res extensa; rather it should be complemented by “res potentia” — in particular, quantum res potentia, not just any old list of possibilities. Quantum potentia can be quantitatively defined; a quantum measurement will, with certainty, always produce one of the possibilities it describes. In the large-scale world, all sorts of possibilities can be imagined (Browns win Super Bowl, Indians win 22 straight games) which may or may not ever come to pass.

If quantum potentia are in some sense real, Kastner and colleagues say, then the mysterious weirdness of quantum mechanics becomes instantly explicable. You just have to realize that changes in actual things reset the list of potential things.

Consider for instance that you and I agree to meet for lunch next Tuesday at the Mad Hatter restaurant (Kastner and colleagues use the example of a coffee shop, but I don’t like coffee). But then on Monday, a tornado blasts the Mad Hatter to Wonderland. Meeting there is no longer on the list of res potentia; it’s no longer possible for lunch there to become an actuality. In other words, even though an actuality can’t alter a distant actuality, it can change distant potential. We could have been a thousand miles away, yet the tornado changed our possibilities for places to eat.

It’s an example of how the list of potentia can change without the spooky action at a distance that Einstein alleged about quantum entanglement. Measurements on entangled particles, such as two photons, seem baffling. You can set up an experiment so that before a measurement is made, either photon could be spinning clockwise or counterclockwise. Once one is measured, though (and found to be, say, clockwise), you know the other will have the opposite spin (counterclockwise), no matter how far away it is. But no secret signal is (or could possibly be) sent from one photon to the other after the first measurement. It’s simply the case that counterclockwise is no longer on the list of res potentia for the second photon. An “actuality” (the first measurement) changes the list of potentia that still exist in the universe. Potentia encompass the list of things that may become actual; what becomes actual then changes what’s on the list of potentia.

Similar arguments apply to other quantum mysteries. Observations of a “pure” quantum state, containing many possibilities, turns one of those possibilities into an actual one. And the new actual event constrains the list of future possibilities, without any need for physical causation. “We simply allow that actual events can instantaneously and acausally affect what is next possible … which, in turn, influences what can next become actual, and so on,” Kastner and colleagues write.

Measurement, they say, is simply a real physical process that transforms quantum potentia into elements of res extensa — actual, real stuff in the ordinary sense. Space and time, or spacetime, is something that “emerges from a quantum substratum,” as actual stuff crystalizes out “of a more fluid domain of possibles.” Spacetime, therefore, is not all there is to reality.

It’s unlikely that physicists everywhere will instantly cease debating quantum mysteries and start driving cars with “res potentia!” bumper stickers. But whether this new proposal triumphs in the quantum debates or not, it raises a key point in the scientific quest to understand reality. Reality is not necessarily what humans think it is or would like it to be. Many quantum interpretations have been motivated by a desire to return to Newtonian determinism, for instance, where cause and effect is mechanical and predictable, like a clock’s tick preceding each tock.

But the universe is not required to conform to Newtonian nostalgia. And more generally, scientists often presume that the phenomena nature offers to human senses reflect all there is to reality. “It is difficult for us to imagine or conceptualize any other categories of reality beyond the level of actual — i.e., what is immediately available to us in perceptual terms,” Kastner and colleagues note. Yet quantum physics hints at a deeper foundation underlying the reality of phenomena — in other words, that “ontology” encompasses more than just events and objects in spacetime.
This proposition sounds a little bit like advocating for the existence of ghosts. But it is actually more of an acknowledgment that things may seem ghostlike only because reality has been improperly conceived in the first place. Kastner and colleagues point out that the motions of the planets in the sky baffled ancient philosophers because supposedly in the heavens, reality permitted only uniform circular motion (accomplished by attachment to huge crystalline spheres). Expanding the boundaries of reality allowed those motions to be explained naturally.

Similarly, restricting reality to events in spacetime may turn out to be like restricting the heavens to rotating spheres. Spacetime itself, many physicists are convinced, is not a primary element of reality but a structure that emerges from processes more fundamental. Because these processes appear to be quantum in nature, it makes sense to suspect that something more than just spacetime events has a role to play in explaining quantum physics.

True, it’s hard to imagine the “reality” of something that doesn’t exist “actually” as an object or event in spacetime. But Kastner and colleagues cite the warning issued by the late philosopher Ernan McMullin, who pointed out that “imaginability must not be made the test for ontology.” Science attempts to discover the real world’s structures; it’s unwarranted, McMullin said, to require that those structures be “imaginable in the categories” known from large-scale ordinary experience. Sometimes things not imaginable do, after all, turn out to be real. No fan of the team ever imagined the Indians would win 22 games in a row.

How do you observe the invisible currents of the atmosphere? By studying the swirling, billowing loads of sand, sea salt and smoke that winds carry. A new simulation created by scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., reveals just how far around the globe such aerosol particles can fly on the wind.

The complex new simulation, powered by supercomputers, uses advanced physics and a state-of-the-art climate algorithm known as FV3 to represent in high resolution the physical interactions of aerosols with storms or other weather patterns on a global scale (SN Online: 9/21/17). Using data collected from NASA’s Earth-observing satellites, the simulation tracked how air currents swept aerosols around the planet from August 1, 2017, through November 1, 2017.
In the animation, sea salt (in blue) snagged by winds sweeping across the ocean’s surface becomes entrained in hurricanes Harvey, Irma, Jose and Maria, revealing their deadly paths. Wisps of smoke (in gray) from fires in the U.S. Pacific Northwest drift toward the eastern United States, while Saharan dust (in brown) billows westward across the Atlantic Ocean to the Gulf of Mexico. And the visualization shows how Hurricane Ophelia formed off the coast of Africa, pulling in both Saharan dust and smoke from Portugal’s wildfires and transporting the particles to Ireland and the United Kingdom.
