Mighty Atom: how the A-bombs shaped Japanese arts

In the 80 years since the World War II attacks, stories of destruction and mutation have been fused with fears around natural disasters and, more recently, the Fukushima crisis. Classic manga and anime series "Astro Boy" is called "Mighty Atom" in Japanese, while city-levelling explosions loom large in other titles such as "Akira", "Neon Genesis Evangelion" and "Attack on Titan". "Living through tremendous pain" and overcoming trauma is a recurrent theme in Japan's cultural output "that global audiences have found fascinating", said William Tsutsui, a history professor at Ottawa University. The US nuclear bombing of Hiroshima on August 6, 1945 left around 140,000 people dead. It was followed days later by the bombing of Nagasaki that killed around 74,000 people. Some poetry "portrays the sheer terror of the atomic bomb at the moment it was dropped", but many novels and artworks address the topic indirectly, said author Yoko Tawada. "It's very difficult for the experience of the atomic bomb, which had never existed in history before, to find a place in the human heart as a memory," she told AFP. Tawada's 2014 book "The Emissary" focuses on the aftermath of an unspecified terrible event. She was inspired by connections between the atomic bombs, the 2011 Fukushima nuclear disaster and "Minamata disease" -- mass mercury poisoning caused by industrial pollution in southwest Japan from the 1950s. The story "is less of a warning, and more a message to say: things may get bad, but we'll find a way to survive", Tawada said. Godzilla's skin Narratives reflecting Japan's complex relationship with nuclear technologies abound, but the most famous example is Godzilla, a prehistoric creature awakened by US hydrogen bomb testing in the Pacific. "We need monsters to give a face and form to abstract fears," said professor Tsutsui, author of the book "Godzilla on My Mind". "In the 1950s, Godzilla fulfilled that role for the Japanese -- with atomic energy, with radiation, with memories of the A-bombs." Many people who watched Godzilla rampage through Tokyo in the original 1954 film left theatres in tears, he said. And "it's said that the special effects people working on Godzilla modelled the monster's heavily furrowed skin after the keloid scars on the survivors of Hiroshima and Nagasaki." In the nearly 40 Godzilla movies released since, nuclear themes are present but often given less prominence, partly to appease American audiences, Tsutsui said. Even so, the series remains hugely popular, with 2016 megahit "Shin Godzilla" seen as a critique of Japan's response to the tsunami-triggered Fukushima disaster. 'Black Rain' "Black Rain", a 1965 novel by Masuji Ibuse about radiation sickness and discrimination, is one of Japan's best-known novels about the Hiroshima bombing. But the fact Ibuse was not an A-bomb survivor is part of a "big debate about who is permitted to write these stories", said Victoria Young of the University of Cambridge. "How we talk about or create literature out of real life is always going to be difficult," she said. "Are you allowed to write about it if you didn't directly experience it?" Nobel-winning author Kenzaburo Oe collected survivor accounts in "Hiroshima Notes", essays written on visits to the city in the 1960s. "He's confronting reality, but tries to approach it from a personal angle" including his relationship with his disabled son, said Tawada, who has lived in Germany for four decades after growing up in Japan. "The anti-war education I received sometimes gave the impression that Japan was solely a victim" in World War II, she said. "When it comes to the bombings, Japan was a victim -- no doubt" but "it's important to look at the bigger picture" including Japan's wartime atrocities, she said. As a child, illustrations of the nuclear bombings in contemporary picture books reminded her of depictions of hell in historical Japanese art. This "made me consider whether human civilisation itself harboured inherent dangers", making atomic weapons feel less like "developments in technology, and more like something latent within humanity".

China Stuns the World With a "Terrifying New Weapon" That Launches Missiles at Mach 7 Using Cutting-Edge Electromagnetic Railgun Technology

IN A NUTSHELL 🚀 Chinese researchers have developed a groundbreaking electromagnetic cannon capable of launching projectiles at Mach 7. capable of launching projectiles at Mach 7. 🔧 The innovative design utilizes a cross-shaped architecture to enhance power and stability without losing precision. to enhance power and stability without losing precision. 💡 This technology aims to reduce costs and eliminate risks associated with explosive storage in military logistics. in military logistics. 🌍 The development could lead to a shift in global military strategy, raising questions about international relations and defense policies. The Chinese military is pushing the boundaries of electromagnetic technology with a groundbreaking new weapon. Researchers have developed an innovative magnetic acceleration system featuring a cross-shaped architecture. This design promises to propel heavier projectiles over strategic distances without losing power. For decades, major military powers have sought ways to launch payloads at extreme speeds without using gunpowder or explosives. The Chinese electromagnetic cannon represents a significant milestone in this pursuit. By combining electromagnetic force with a cross-architecture, this experimental weapon can potentially launch a projectile at Mach 7 without sacrificing durability or accuracy. This technological advancement challenges the limits previously imposed by heat and material constraints. Innovative Design Challenges the Laws of Physics The railgun is no longer a fringe invention. Since 2018, China has been testing a prototype installed on the Haiyangshan ship. It pushes the limits of magnetic acceleration far beyond the laboratory. Yet, a significant weakness still hampers these weapons. The intense current can melt certain parts, and sometimes the force of the magnetic fields can tear apart metal structures. To overcome this barrier, a team led by Professor Lyu Qingao at the People's Liberation Army Engineering University has envisioned a cannon that crosses two railguns in a single tube, at right angles. Each circuit is autonomous and oriented perpendicularly to the other, allowing for increased power without electromagnetic fields interfering with each other. According to the South China Morning Post, this X-shaped system could launch a 132-pound projectile at over 5,300 mph, while circumventing the destructive effects of heat and power surges. 'They're Not Supposed to Be This Fast': China's Maglev Shockingly Nears Japan's Bullet Train Speeds in High-Stakes Tech Showdown Chinese Electromagnetic Cannon Reinvents Gunpowder-Free Artillery Unlike conventional missiles or shells, this type of cannon relies neither on combustion nor chemical propulsion. The entire operation rests on the linear acceleration of a metal projectile under the influence of magnetic fields. This technology not only reduces the cost per shot but also eliminates risks related to the storage of explosives. This is a major strategic advantage in a world where military logistics must contend with drone strikes and asymmetric conflicts. According to Interesting Engineering, the new Chinese prototype aims to hit a target located 250 miles away in just six minutes, with an impact speed exceeding Mach 4. The level of precision combined with speed would make these projectiles as formidable as some cruise missiles, while being more difficult to intercept and much cheaper to produce. 'They Just Flew It in Broad Daylight': China's Secret 6th-Gen Fighter Jet Stuns Drivers as It Soars Over Crowded Highway This shift in the design of long-range weapons stands in stark contrast to Western choices. The United States ended its electric cannon program in 2021, deeming the technological challenges too costly compared to advances in hypersonic missiles. Japan, on the other hand, continues more modest trials with projectiles weighing only 0.66 pounds, according to Asia Times. From Experimentation to Battlefields of the Future While the cross-system promises unprecedented firepower, its viability in real-world conditions remains to be proven. The Chinese researchers themselves acknowledge several uncertainties. The phenomenon known as the 'proximity effect,' where two very close electrical circuits can alter each other's performance, could lead to efficiency losses or critical instabilities during firing. 'They Can See Us Even in Silence': China's New Magnetic Wake Tech Shatters Submarine Stealth in Shallow Waters Like the Taiwan Strait Furthermore, no operational condition tests have yet been conducted. The prototype remains confined to laboratories and recently filed patents, such as one titled 'X-Frame Electromagnetic Cannon.' However, if these limitations are overcome, this weapon could change how conflicts are conceived and anticipated. The uniqueness of the Chinese electric cannon lies in its ability to combine power, speed, and low cost while avoiding the vulnerabilities of conventional systems. This approach, which focuses on reusable and scalable technology, contrasts with the hesitation of competing powers. By betting on this breakthrough, China is forging a new path in the history of modern artillery. Military Implications and Global Reactions The development of the Chinese electromagnetic cannon could have profound implications for global military strategy. As nations worldwide assess the potential of this technology, questions arise about its impact on international relations and defense policies. While some countries may rush to develop similar capabilities, others might seek to establish treaties limiting their use. The balance of power could shift as nations with advanced electromagnetic weaponry gain a strategic advantage. This might lead to an arms race focused on electromagnetic technology. The potential for these weapons to reach targets with unprecedented speed and precision raises ethical and logistical questions. How will this influence future conflicts, and what measures will be necessary to ensure responsible use? As the Chinese electromagnetic cannon continues to evolve, the world watches closely. Its potential to reshape military dynamics cannot be understated. The path forward will require careful consideration of technological, ethical, and geopolitical factors. Will the international community find ways to harness this technology responsibly, or will it lead to heightened tensions and conflict?
