134-460: Takashi Murakami ( 村上 隆 , Murakami Takashi , born February 1, 1962) is a Japanese contemporary artist . He works in fine arts (such as painting and sculpture) as well as commercial media (such as fashion , merchandise, and animation) and is known for blurring the line between high and low arts . His influential work draws from the aesthetic characteristics of the Japanese artistic tradition and

268-400: A nuclear chain reaction . This was accomplished by shooting one piece of the uranium onto the other by means of four cylindrical silk bags of cordite powder. This was a widely used smokeless propellant consisting of a mixture of 65 percent nitrocellulose , 30 percent nitroglycerine , 3 percent petroleum jelly , and 2 percent carbamite that was extruded into tubular granules. This gave it

402-438: A PV, directed by Murakami, for Redial, featuring Hatsune Miku . In April 2013, Murakami's first feature film was released in theaters across Japan. Jellyfish Eyes (originally titled "Me me me no kurage)) is a live-action movie featuring CGI characters designed by Murakami called Friend. In 2019, Murakami was working on his own album of original folk songs, inspired by Japanese group Happy End . Murakami's art encompasses

536-493: A T-shirt by Billionaire Boys Club , the brand co-founded by Pharrell and Nigo . In Fall of 2015, Takashi collaborated with Vans. The name of this collaboration was Vault By Vans x Takashi Murakami Collection. His artwork was on Vans classic slip on, apparel and skateboard decks for an illuminated time and only in selected stores. His artwork mostly consisted of his famous skull and flower designs.   In 2018, Takashi Murakami collaborated with fashion designer Virgil Abloh on

670-569: A Winter Solstice doodle for the Southern Hemisphere. In February 2012, Murakami opened an exhibition in Doha , Qatar. Titled Murakami-Ego , this showed around 60 old works alongside new ones designed especially for the exhibition. Among the new ones, a 100-metre long wall painting depicting the suffering of the Japanese people after the Fukushima nuclear disaster . In March 2013, livetune released

804-529: A bit over 7 feet tall, of an anime character with oversized lactating breasts whose milk stream forms a jump rope made of fiberglass, sold for $ 427,500 at Christie's auction house in May 2002. Miss ko2 (1996), a 6-foot-tall model of an anime-inspired blonde girl in a red and white maid outfit, was sold for $ 567,500 in 2003, and was put up for auction in 2010, where it sold for 22.9 million HKD. In May 2008, My Lonesome Cowboy (1998) , an anime-inspired sculpture of

Murakami and McG directed short Akihabara Majokko Princess , where Kirsten Dunst sings a cover of The Vapors ' 1980 song " Turning Japanese ". This was shown at the "Pop Life" exhibition in London's Tate Modern museum from October 1, 2009, to January 17, 2010. It shows Dunst dancing around Akihabara ,

1072-424: A contemporary artist" and that they "are in it for all the wrong reasons." Some competitions, awards, and prizes in contemporary art are: This table lists art movements and styles by decade. It should not be assumed to be conclusive. Little Boy Little Boy is the name of the type of atomic bomb used in the bombing of the Japanese city of Hiroshima on 6 August 1945 during World War II , making it

1206-457: A copy of the complete design. Unlike the implosion design, which required sophisticated coordination of shaped explosive charges, the gun-type design was considered almost certain to work so it was never tested before its first use at Hiroshima. After the war, numerous components for additional Little Boy bombs were built. By 1950, five complete weapons had been created, and these were retired by November 1950. There are two primary accounts of how

1340-419: A crash that could destroy or damage the military base from which the weapon was launched. The Little Boy was 120 inches (300 cm) in length, 28 inches (71 cm) in diameter and weighed approximately 9,700 pounds (4,400 kg). The design used the gun method to explosively force a hollow sub- critical mass of enriched uranium and a solid target cylinder together into a super-critical mass, initiating

1474-526: A culture with little distinction between 'high' and 'low'. The theory provided the context for his work and he elaborated on it with the exhibitions "Coloriage" (2002, Fondation Cartier pour l'art contemporain, Paris) and " Little Boy: The Arts of Japan's Exploding Subculture " (2005, Japan Society, New York), which was named after Little Boy . These helped introduce Japan's lesser-known creative culture overseas and such curatorial projects would become an integral part of Murakami's multifaceted artistic practice. In

1608-640: A form of self-portraiture, the first of several endlessly morphing and recurring motifs seen throughout his work. Though he garnered attention, many of his early pieces were not initially well received in Japan. In 1994, Murakami received a fellowship from the Asian Cultural Council and participated in the PS1 International Studio Program in New York City for a year. During his stay, he

1742-689: A frustration with the lack of a reliable and sustainable art market in postwar Japan. Largely for this reason, he formulated a strategy wherein he would first establish himself in the Western art world and then import himself back to Japan, building a new type of art market in the process. In order to create something rooted in his own Japanese culture and history but still fresh and valid internationally, he began searching for something that could be considered 'uniquely Japanese.' After concluding that elements of 'high' art were confounding at best, he began to focus on Japan's 'low' culture, especially anime and manga, and

1876-435: A fuel. All the design, development, and technical work at Los Alamos was consolidated under Lieutenant Commander Francis Birch 's group. In contrast to the plutonium implosion-type nuclear weapon and the plutonium gun-type fission weapon, the uranium gun-type weapon was much simpler to design. As a high-velocity gun was no longer required, the overall length of the gun barrel could be dramatically decreased, and this allowed

2010-498: A full-scale test in the implosion-type design made it much more difficult to establish whether the necessary simultaneity of compression had been achieved. While there was at least one prominent scientist ( Ernest O. Lawrence ) who advocated for a full-scale test, by early 1945 Little Boy was regarded as nearly a sure thing and was expected to have a higher yield than the first-generation implosion bombs. Though Little Boy incorporated various safety mechanisms, an accidental detonation of

2144-459: A fully-assembled weapon was very possible. Should the bomber carrying the device crash, the hollow "bullet" could be driven into the "target" cylinder, possibly detonating the bomb from gravity alone (though tests suggested this was unlikely), but easily creating a critical mass that would release dangerous amounts of radiation. A crash of the B-29 and subsequent fire could trigger the explosives, causing

2278-502: A high surface area and a rapid burning area, and could attain pressures of up to 40,000 pounds per square inch (280,000 kPa). Cordite for the wartime Little Boy was sourced from Canada; propellant for post-war Little Boys was obtained from the Picatinny Arsenal . The bomb contained 64 kilograms (141 lb) of enriched uranium. Most was enriched to 89% but some was only 50% uranium-235, for an average enrichment of 80%. Less than

2412-448: A kilogram of uranium underwent nuclear fission , and of this mass only 0.7 grams (0.025 oz) was transformed into several forms of energy, mostly kinetic energy , but also heat and radiation. Inside the weapon, the uranium-235 material was divided into two parts, following the gun principle: the "projectile" and the "target". The projectile was a hollow cylinder with 60% of the total mass (38.5 kilograms [85 lb]). It consisted of

2546-635: A masturbating boy whose semen stream forms a lasso, sold for $ 15.2 million at Sotheby's , making it his most highly valued piece. Murakami's current net-worth is estimated to be around US$ 100 million, and the value of his works continue to rise in today's market. Murakami has incorporated his operations as Kaikai Kiki Co., Ltd. in Japan (2001), Kaikai Kiki New York, LLC in New York (2001), and Kaikai Kiki LA, LLC in Los Angeles (2010). The name "Kaikai Kiki" (カイカイキキ) which means "brave, strong and sensitive",

The company began in Saitama, Japan in Asaka City , and now has offices in Tokyo, Japan in

2814-413: A particular issue; galleries and critics are often reluctant to divide their work between the contemporary and non-contemporary. Sociologist Nathalie Heinich draws a distinction between modern and contemporary art, describing them as two different paradigms which partially overlap historically. She found that while " modern art " challenges the conventions of representation , "contemporary art" challenges

2948-403: A permanent collection of contemporary art inevitably find this aging. Many use the formulation "Modern and Contemporary Art", which avoids this problem. Smaller commercial galleries, magazines and other sources may use stricter definitions, perhaps restricting the "contemporary" to work from 2000 onwards. Artists who are still productive after a long career, and ongoing art movements , may present

3082-462: A press release that the anime -style video, which was animated using motion capture technology, took eight months for him to create. The video opens with an animated version of Eilish, dressed in a neon-green shirt and shorts, eventually morphing into a spider-like monster that wreaks havoc on a miniature city. The video features the "Blohsh", Eilish's signature logo, as well as Murakami's flowers . The late rapper Juice WRLD approached Murakami to do

3216-425: A project several weeks before his untimely death, as a result of which, the projected could never be completed. In March 2020, J Balvin released his album Colores featuring album cover designs and artwork by Takashi Murakami. The Murakami-designed artwork was carried over to merchandise to celebrate the release of his album. In April 2020, Supreme released a Box Logo Tee featuring artwork from Murakami. All

3350-474: A propellent, or creating a "double gun" with two projectiles) were pursued in the early years of the project, while the facilities to manufacture fissile material were being constructed. The belief that the gun design would be an easy engineering task once fuel was available led to a sense of optimism at Los Alamos, although Oppenheimer established a small research group to study implosion as a fallback in early 1943. A full ordnance program for gun-design development

The enriched uranium projectile was completed on 15 June, and the target was completed on 24 July. The target and bomb pre-assemblies (partly assembled bombs without the fissile components) left Hunters Point Naval Shipyard , California, on 16 July aboard

3618-481: A series of artworks, bringing the fashion world to the art world but ultimately transcending both to create something more. Takashi and Virgil discuss their careers and their collaboration at length in their interview for Cultured Magazine's fall 2018 issue where they are featured on the cover. In March 2019, Billie Eilish released one of two official music videos for " You Should See Me in a Crown ", one being directed and animated by Takashi Murakami. Murakami stated in

3752-553: A shopping district in Tokyo, Japan. In May 2014, with Pharrell and Kz of livetune , Murakami created a music video for the remix of the Hatsune Miku song "Last Night, Good Night (Re:Dialed)". The team was assembled by the YouTube channel The Creators Project, headed by Vice and Intel . The same year, Murakami's anime-inspired illustrations from his first film Jellyfish Eyes, also adorned

3886-569: A single firestorm, and the fire-damaged area was only one-quarter as great as at Hiroshima, due in part to a southwest wind that pushed the fires away from the city. As the map shows, the Hiroshima firestorm jumped natural firebreaks (river channels), as well as prepared firebreaks. The spread of fire stopped only when it reached the edge of the blast-damaged area, encountering less available fuel. The Manhattan Project report on Hiroshima estimated that 60% of immediate deaths were caused by fire, but with

4020-474: A spiral trail of semen circling him. This piece is Murakami's most expensive piece to date selling for $ 15,100,000 at Sotheby's New York auction in 2008. Efforts from this period include performance art (Osaka Mixer Project, 1992), parodies of the "message" art popular in Japan in the early '90s, (Dobozite Dobozite Oshamanbe, 1993), and conceptual works (e.g. Randoseru Project, 1991). He also began developing his own pop icon, "Mr. DOB", which would later develop into

4154-401: A stack of nine uranium rings, each 6.25 inches (159 mm) in diameter with a 4-inch (100 mm) bore in the center, and a total length of 7 inches (180 mm), pressed together into the front end of a thin-walled projectile 16.25 inches (413 mm) long. Filling in the remainder of the space behind these rings in the projectile was a tungsten carbide disc with a steel back. At ignition,

4288-451: A tamper and neutron reflector of tungsten carbide and steel, both materials having a combined mass of 2,300 kilograms (5,100 lb). Neutron initiators inside the assembly were activated by the impact of the projectile into the target. The material was split almost in half, with at one end a group of rings of highly enriched uranium with 40% of the supercritical mass, and at the other end another group of slightly larger rings with 60% of

4422-537: A truck driver and model maker from Illinois who had studied every photograph and document on the Hiroshima bomb to make an accurate model, corrected earlier published accounts. The fuzing system was designed to trigger at the most destructive altitude, which calculations suggested was 1,900 feet (580 m). It employed a three-stage interlock system: The Little Boy pre-assemblies were designated L-1, L-2, L-3, L-4, L-5, L-6, L-7, and L-11. Of these, L-1, L-2, L-5, and L-6 were expended in test drops. The first drop test

4556-558: A wide range of media and is generally described as superflat. It has been noted for its use of color, incorporation of motifs from Japanese traditional and popular culture, flat/glossy surfaces, and content that could be described at once as "cute", "psychedelic", or "satirical". Among his best known recurring motifs are smiling flowers, Mr. DOB, mushrooms, skulls, Buddhist iconography, and the sexual complexes of otaku culture. One of Murakami's most famous pieces known as 'Hiropon' brings to light his embrace of otaku culture. The sculpture that

4690-543: Is "distinguished by the very lack of a uniform organizing principle, ideology, or - ism" that is seen in many other art periods and movements. Contemporary art does not have one, single objective or point of view, so it can be contradictory and open-ended. There are nonetheless several common themes that have appeared in contemporary works, such as identity politics , the body, globalization and migration, technology , contemporary society and culture, time and memory, and institutional and political critique. The functioning of

4824-480: Is a legitimate and reasonable response to much contemporary art. Brian Ashbee in an essay called "Art Bollocks" criticizes "much installation art, photography, conceptual art , video and other practices generally called post-modern" as being too dependent on verbal explanations in the form of theoretical discourse. However, the acceptance of nontraditional art in museums has increased due to changing perspectives on what constitutes an art piece. A common concern since

4958-406: Is common to anime and manga enterprises, such as Hayao Miyazaki 's Studio Ghibli . In 2001, Hiropon Factory was incorporated as Kaikai Kiki Co., Ltd. In 2002, at the invitation of designer Marc Jacobs , Murakami began his long-lasting collaboration with the fashion brand Louis Vuitton . He began by contributing artwork which was used in the design of a series of handbags. The series re-envisioned

5092-532: Is contemporary is naturally always on the move, anchored in the present with a start date that moves forward, and the works the Contemporary Art Society bought in 1910 could no longer be described as contemporary. Particular points that have been seen as marking a change in art styles include the end of World War II and the 1960s. There has perhaps been a lack of natural break points since the 1960s, and definitions of what constitutes "contemporary art" in

5226-511: Is exhibited by professional artists at commercial contemporary art galleries , by private collectors, art auctions , corporations, publicly funded arts organizations, contemporary art museums or by artists themselves in artist-run spaces . Contemporary artists are supported by grants, awards, and prizes as well as by direct sales of their work. Career artists train at art school or emerge from other fields. There are close relationships between publicly funded contemporary art organizations and

5360-417: Is simply beautiful." Contemporary art can sometimes seem at odds with a public that does not feel that art and its institutions share its values. In Britain, in the 1990s, contemporary art became a part of popular culture, with artists becoming stars, but this did not lead to a hoped-for "cultural utopia". Some critics like Julian Spalding and Donald Kuspit have suggested that skepticism, even rejection,

Another explanation of the names, from a classified United States Air Force history of Project Silverplate from the 1950s, implies a possible reconciliation of the two versions: that the terms "Thin Man" and "Fat Man" were first developed by someone at or from Los Alamos (i.e., Serber), but were consciously adopted by

Sarah Thornton tracks the early stages of the exhibition's planning, including in-depth curatorial meetings between Murakami and prominent museum figures, in Seven Days in the Art World . The exhibition earned widespread attention for, among other things, including a fully functioning Louis Vuitton boutique as one of the exhibits. In 2008, Murakami was named one of Time magazine's "100 Most Influential People",

5762-471: The Hanford Site was designed to produce around 20 kilograms of plutonium per month, and each Fat Man bomb used around 6 kilograms of material.) Because of the simplicity of the gun-type design, laboratory testing could establish that its parts worked correctly on their own: for example, dummy projectiles could be shot down the gun barrel to make sure they were "seated" correctly onto a dummy target. Absence of

5896-546: The Moto-Azabu neighborhood and New York as well as affiliates in Berlin and Taiwan. From 2002 until 2014, Murakami organized a unique direct-participatory art fair called Geisai. It was held once per year in Japan and once per year in a different city, such as Taipei , or Miami . Rather than give space to pre-screened galleries, the fair allowed artists to create their own booths and interact directly with potential buyers. Murakami

The bomb, except for the uranium payload, was ready at the beginning of May 1945. Manhattan District Engineer Kenneth Nichols expected on 1 May 1945 to have enriched uranium "for one weapon before August 1 and

6164-455: The Trinity nuclear test . Since that had been estimated at 18 kilotons of TNT (75 TJ), speech writers rounded up to 20 kilotons. Further discussion was then suppressed, for fear of lessening the impact of the bomb on the Japanese. Data had been collected by Luis Alvarez , Harold Agnew , and Lawrence H. Johnston on the instrument plane, The Great Artiste , but this was not used to calculate

6298-492: The Trinity nuclear test . There were several reasons for not testing a Little Boy type of device. Primarily, there was the issue of fissile material availability. K-25 at Clinton Engineer Works was designed to produce around 30 kilograms of enriched uranium per month, and the Little Boy design used over 60 kilograms per bomb. So testing the weapon would incur a considerable delay in use of the weapon. (By comparison, B Reactor at

6432-455: The heavy cruiser USS  Indianapolis , arriving on 26 July. The target inserts followed by air on 30 July. Although all of its components had been individually tested, no full test of a gun-type nuclear weapon occurred before the Little Boy was dropped over Hiroshima . The only test explosion of a nuclear weapon concept had been of an implosion-type device employing plutonium as its fissile material, which took place on 16 July 1945 at

6566-503: The nuclear fission of uranium-235 , whereas Thin Man was based on fission of plutonium-239 . Fission was accomplished by shooting a hollow cylinder (the "bullet") onto a solid cylinder of the same material (the "target") by means of a charge of nitrocellulose propellant powder. Little Boy contained 64 kilograms (141 lb) of highly enriched uranium , although less than a kilogram underwent nuclear fission. Its components were fabricated at three different plants so that no one would have

6700-424: The stratosphere , where they dissipate and become part of the global environment. Because Little Boy was an air burst 580 meters (1,900 ft) above the ground, there was no bomb crater and no local radioactive fallout. However, a burst of intense neutron and gamma radiation came directly from the fission of the uranium. Its lethal radius was approximately 1.3 kilometers (0.8 mi), covering about half of

6834-582: The "Fat Man." In September 1945, another Project Alberta physicist, Norman F. Ramsey , stated in his brief "History of Project A," that the early bomb ballistic test shapes designs were referred to as "Thin Man" and "Fat Man" by (unspecified) " Air Force representatives" for "security reasons," so that their communications over telephones sounded "as if they were modifying a plane to carry Roosevelt (the Thin Man) and Churchill (the Fat Man)," as opposed to modifying

6968-465: The 'traditional' style of Japanese painting that incorporates traditional Japanese artistic conventions, techniques and subjects. He earned his master's degree in 1988. Though he would go on to earn a Ph.D. in Nihonga (1993), he gradually became disillusioned with its insular, highly political world and started to explore more contemporary artistic styles, media, and strategies. Murakami was dissatisfied with

7102-507: The 2010s vary, and are mostly imprecise. Art from the past 20 years is very likely to be included, and definitions often include art going back to about 1970; "the art of the late 20th and early 21st century"; "both an outgrowth and a rejection of modern art"; "Strictly speaking, the term 'contemporary art' refers to art made and produced by artists living today"; "Art from the 1960s or [19]70s up until this very minute"; and sometimes further, especially in museum contexts, as museums which form

The picture at right shows the effects of a nuclear bomb-generated 5 psi pressure wave on a test structure in Nevada in 1953. A major effect of this kind of structural damage was that it created fuel for fires that were started simultaneously throughout

Contemporary artists work in a globally influenced , culturally diverse , and technologically advancing world. Their art is a dynamic combination of materials , methods, concepts, and subjects that continue the challenging of boundaries that

7504-603: The Director of the Manhattan Project, Major General Leslie R. Groves , ordered that some Little Boys be prepared as an interim measure until a solution could be found. No Little Boy assemblies were available, and no comprehensive set of diagrams of the Little Boy could be found, although there were drawings of the various components, and stocks of spare parts. At Sandia Base , three Army officers, Captains Albert Bethel, Richard Meyer, and Bobbie Griffin attempted to re-create

7638-566: The Little Boy. They were supervised by Harlow W. Russ, an expert on Little Boy who served with Project Alberta on Tinian, and was now leader of the Z-11 Group of the Los Alamos Laboratory's Z Division at Sandia. Gradually, they managed to locate the correct drawings and parts, and figured out how they went together. Eventually, they built six Little Boy assemblies. Although the casings, barrels, and components were tested, no enriched uranium

7772-607: The Naval Ordnance Plants in Pocatello, Idaho , and Louisville, Kentucky . Enough fissionable material was available by 1948 to build ten projectiles and targets, although there were only enough initiators for six. However, no actual fissionable components were produced by the end of 1948, and only two outer casings were available. By the end of 1950, only five complete Little Boy assemblies had been built. All were retired by November 1950. The Smithsonian Institution displayed

8040-490: The art world is dependent on art institutions, ranging from major museums to private galleries, non-profit spaces, art schools and publishers, and the practices of individual artists, curators, writers, collectors, and philanthropists. A major division in the art world is between the for-profit and non-profit sectors, although in recent years the boundaries between for-profit private and non-profit public institutions have become increasingly blurred. Most well-known contemporary art

8174-489: The atomic bomb would not be difficult to design and that the difficulty would lie only in the production of fuel. Calculations in mid-1942 by theoretical physicists working on the project reinforced the idea that an ordinary artillery gun barrel would be able to impart sufficient velocity to the fissile material projectile. Several different weapon designs, including autocatalytic assembly, a nascent version of implosion, and alternative gun designs (e.g., using high explosives as

Jeppson held a flashlight while Parsons disconnected the primer wires, removed the breech plug, inserted the powder bags, replaced the breech plug, and reconnected the wires. Before climbing to altitude on approach to the target, Jeppson switched the three safety plugs between the electrical connectors of the internal battery and the firing mechanism from green to red. The bomb

8576-555: The bomb was test dropped near Tinian. L-11 was the assembly used for the Hiroshima bomb, and was fully assembled with its nuclear fuel by 31 July. Parsons, the Enola Gay ' s weaponeer, was concerned about the possibility of an accidental detonation if the plane crashed on takeoff, so he decided not to load the four cordite powder bags into the gun breech until the aircraft was in flight. After takeoff, Parsons and his assistant, Second Lieutenant Morris R. Jeppson , made their way into

Sweeney , flew to Iwo Jima , where emergency procedures for loading the bomb onto a standby aircraft were practiced. This rehearsal was repeated on 31 July, but this time L-6 was reloaded onto a different B-29, Enola Gay , piloted by Tibbets, and

8844-509: The boundaries between art and commercial branding and even questioning the existence of such a boundary. Asked about straddling the line between art and commercial products, Murakami responded: I don't think of it as straddling. I think of it as changing the line. What I've been talking about for years is how in Japan, that line is less defined. Both by the culture and by the post-War economic situation. Japanese people accept that art and commerce will be blended; and in fact, they are surprised by

8978-524: The catalogue for a group exhibition of the same name that he curated for the Museum of Contemporary Art, Los Angeles . The theory posits that there is a legacy of flat, 2-dimensional imagery from Japanese art history in manga and anime. This style differentiates itself from the western approach in its emphasis on surface and use of flat planes of color. Superflat also served as a commentary on postwar Japanese society in which, Murakami argues, differences in social class and popular taste have 'flattened,' producing

9112-415: The caveat that "many persons near the center of explosion suffered fatal injuries from more than one of the bomb effects." Local fallout is dust and ash from a bomb crater, contaminated with radioactive fission products. It falls to earth downwind of the crater and can produce, with radiation alone, a lethal area much larger than that from blast and fire. With an air burst , the fission products rise into

9246-463: The city. The Hiroshima bombing was the second nuclear explosion in history, after the Trinity nuclear test . Little Boy was developed by Lieutenant Commander Francis Birch 's group at the Manhattan Project 's Los Alamos Laboratory during World War II, a reworking of their abandoned Thin Man nuclear bomb. Like Thin Man, it was a gun-type fission weapon . It derived its explosive power from

9380-623: The commercial sector. For instance, in 2005 the book Understanding International Art Markets and Management reported that in Britain a handful of dealers represented the artists featured in leading publicly funded contemporary art museums. Commercial organizations include galleries and art fairs. Corporations have also integrated themselves into the contemporary art world , exhibiting contemporary art within their premises, organizing and sponsoring contemporary art awards, and building up extensive corporate collections.

Though he had previously collaborated with fashion designers such as Issey Miyake Men by Naoki Takizawa , his work with Louis Vuitton made him widely known for blurring the line between 'high art' and commercialism. It also elevated him to celebrity status in his home country of Japan. In 2007, Murakami provided the cover artwork for rapper Kanye West 's album Graduation and directed an animated music video for West's song " Good Morning ." He also provided cover artwork for West's 2018 collaboration album Kids See Ghosts with Kid Cudi . For Graduation and "Good Morning", Murakami would later 're-appropriate' these projects by incorporating their imagery into his paintings and sculptures, further blurring

9648-519: The conditions for a large-scale explosion. As a consequence of the discovery of the Pu-240 contamination problem, in July 1944 almost all research at Los Alamos was redirected to the implosion-type plutonium weapon, and the laboratory was entirely reorganized around the implosion problem. Work on the gun-type weapon continued under Person's Ordnance (O) Division, for use exclusively with highly enriched uranium as

9782-496: The damage and the number of victims at Hiroshima were much higher, as Hiroshima was on flat terrain, while the hypocenter of Nagasaki lay in a small valley. According to figures published in 1945, 66,000 people were killed as a direct result of the Hiroshima blast, and 69,000 were injured to varying degrees. Later estimates put the deaths as high as 140,000 people. The United States Strategic Bombing Survey estimated that out of 24,158 Imperial Japanese Army soldiers in Hiroshima at

9916-425: The difference in uncertainty owing to having better data on the latter. To put these numerical differences into context, it is necessary to know that the acute effects of nuclear detonations, especially the blast and thermal effects, do not scale linearly, but generally as a cubic root . Specifically, the distance of these effects scale as a function of the yield raised to an exponential power of 1 ⁄ 3 . So

10050-418: The early part of the 20th century has been the question of what constitutes art. In the contemporary period (1970 to now), the concept of avant-garde may come into play in determining what artworks are noticed by galleries, museums, and collectors. The concerns of contemporary art come in for criticism too. Andrea Rosen has said that some contemporary painters "have absolutely no idea of what it means to be

10184-460: The energy yield of the untested Little Boy design could be determined only at the moment of detonation, using instruments dropped by parachute from a plane flying in formation with the one that dropped the bomb. Radio-transmitted data from these instruments indicated a yield of about 15 kilotons. Comparing this yield to the observed damage produced a rule of thumb called the 5 pounds per square inch (34  kPa ) lethal area rule. Approximately all

10318-504: The firestorm area. An estimated 30% of immediate fatalities were people who received lethal doses of this direct radiation, but died in the firestorm before their radiation injuries would have become apparent. Over 6,000 people survived the blast and fire, but died of radiation injuries. Among injured survivors, 30% had radiation injuries from which they recovered, but with a lifelong increase in cancer risk. To date, no radiation-related evidence of heritable diseases has been observed among

10452-494: The first atomic bombs got their names. Los Alamos Laboratory and Project Alberta physicist Robert Serber stated, many decades after the fact, that he had named the first two atomic bomb designs during World War II based on their shapes: Thin Man and Fat Man . The "Thin Man" was a long, thin device, and its name came from the Dashiell Hammett detective novel and series of movies about The Thin Man . The "Fat Man"

10586-459: The first fifty years after 1945, every published description and drawing of the Little Boy mechanism assumed that a small, solid projectile was fired into the center of a larger, stationary target. However, critical mass considerations dictated that in Little Boy the more extensive, hollow piece would be the projectile. Hollow cylinders have higher critical masses than solid pieces of fissile material, because any neutrons encountered by or generated by

10720-532: The first nuclear weapon used in warfare. The bomb was dropped from the Boeing B-29 Superfortress Enola Gay piloted by Colonel Paul W. Tibbets Jr. , commander of the 509th Composite Group , and Captain Robert A. Lewis . It exploded with an energy of approximately 15 kilotons of TNT (63  TJ ) and had an explosion radius of approximately 1.3 kilometers which caused widespread death across

10854-478: The hypocenter, left a permanent shadow , having absorbed the fireball heat that permanently bleached the surrounding stone. Simultaneous fires were started throughout the blast-damaged area by fireball heat and by overturned stoves and furnaces, electrical shorts, etc. Twenty minutes after the detonation, these fires had merged into a firestorm , pulling in surface air from all directions to feed an inferno which consumed everything flammable. The Hiroshima firestorm

10988-463: The issues. In 1982, Los Alamos created a replica Little Boy from the original drawings and specifications. This was then tested with enriched uranium but in a safe configuration that would not cause a nuclear explosion. A hydraulic lift was used to move the projectile, and experiments were run to assess neutron emission. After hostilities ended, a survey team from the Manhattan Project that included William Penney , Robert Serber, and George T. Reynolds

11122-557: The larger subculture of otaku . His artistic style and motifs (cute [ kawaii ]/disturbing anime-esque characters rendered in bright colors, flat and highly glossy surfaces, life-size sculptures of anime figurines) derived from this strategy. This is demonstrated in his whimsical Cosmos Ball from 2000, in the collection of the Honolulu Museum of Art . On November 11, 2003, ARTnews has described Murakami's work as being in great demand. Hiropon (1997), satirical sculpture, standing

11256-412: The material are more likely to get scattered in the air than to continue a chain reaction. The larger piece would also avoid the effects of neutron reflection from the tungsten carbide tamper until it was fully joined with the rest of the fuel. Once joined and with its neutrons reflected, the assembled fissile core would comprise more than two critical masses of uranium-235. In 2004, John Coster-Mullen ,

11390-414: The nature of postwar Japanese culture . He designed the album covers for Kanye West 's third studio album Graduation , Future 's eponymous fifth studio album , West and Kid Cudi ’s collaborative studio album Kids See Ghosts , and the late Juice Wrld 's The Party Never Ends . Murakami is the founder and President of Kaikai Kiki Co., Ltd., through which he manages several younger artists. He

11524-475: The officers in Silverplate when they were adopting their own codenames for their own project (including "Silverplate"). As Silverplate involved modifying B-29s for a secret purpose, deliberately using codenames that would align with modifying vehicles for Roosevelt and Churchill would serve their needs well. Because of its perceived simplicity, the gun-type nuclear weapon design was the first approach pursued by

11658-496: The only visual artist included. In September 2010 Murakami became the third contemporary artist, and first Japanese, to exhibit at the Palace of Versailles in France, filling 15 rooms and the park with his sculptures, paintings, a decorative carpet, and lamps. On June 21, 2011, Google featured a doodle tagged as "First Day of Summer" which was created by Murakami. This was accompanied by

11792-513: The organization and operation of the Geisai art fair. Having earned success and recognition internationally, Murakami has devoted himself to nurturing and supporting the careers of a younger generation of Japanese artists. Likening the operation to that of a record label, he offers both logistic support and practical career advice. Through this endeavor, he also seeks to build an original and sustainable art market in Japan. In 2008, Kaikai Kiki converted

11926-463: The past decade, Murakami's curatorship expanded to include Kazunori Hamana, Yuji Uedaa, and Otani Workshop at Blum & Poe, New York (2016) and Juxtapox x Superflat at Vancouver Art Gallery (2016). In accordance with the Superflat concept, Murakami's practice involves repackaging elements usually considered "low" or subcultural and presenting them in the "high-art" market. He then further flattens

12060-420: The people inside the area where the shock wave carried such an overpressure or greater would be killed. At Hiroshima, that area was 2.2 miles (3.5 km) in diameter. The damage came from three main effects: blast, fire, and radiation. The blast from a nuclear bomb is the result of X-ray -heated air (the fireball) sending a shock wave or pressure wave in all directions, initially at a velocity greater than

12194-472: The playing field by repackaging his "high-art" works as merchandise, such as plush toys and T-shirts, making them available at more affordable prices. In 1996, Murakami launched the Hiropon Factory, his production workshop, in order to work on a larger scale and in a more diverse array of media. His model inherits the atelier system which has long existed in Japanese painting, printmaking and sculpture and

12328-514: The point directly under the explosion was completely destroyed, except for about 50 heavily reinforced, earthquake-resistant concrete buildings, only the shells of which remained standing. Most were completely gutted, with their windows, doors, sashes, and frames ripped out. The perimeter of severe blast damage approximately followed the 5 pounds per square inch (34 kPa) contour at 1.1 miles (1.8 km). Later test explosions of nuclear weapons with houses and other test structures nearby confirmed

12462-500: The practical differences in effects at these yield ranges are smaller than may at first appear, if one assumes that there is a linear relationship between yield and damage. Although Little Boy exploded with the energy equivalent of around 15 kilotons of TNT, in 1946 the Strategic Bombing Survey estimated that the same blast and fire effect could have been caused by 2.1 kilotons of conventional bombs distributed evenly over

12596-425: The presence of the isotope plutonium-240 (Pu-240) raised the rate of spontaneous fission of the plutonium to an unacceptable amount. Previous analyses of plutonium had been made from samples created by cyclotrons and did not have as much of the contaminating isotope. If reactor-bred plutonium was used in a gun-type design, they concluded, it would predetonate , causing the weapon to destroy itself before achieving

12730-554: The prestige associated with contemporary art and coolhunting to draw the attention of consumers to luxury goods . The institutions of art have been criticized for regulating what is designated as contemporary art. Outsider art , for instance, is literally contemporary art, in that it is produced in the present day. However, one critic has argued it is not considered so because the artists are self-taught and are thus assumed to be working outside of an art historical context. Craft activities, such as textile design, are also excluded from

12864-576: The proceeds went to HELP USA, in order to support youth and families facing homelessness during the COVID-19 pandemic . In 2022, a collaboration between Sir Lewis Hamilton and Murakami was announced for Hamilton's '+44' fashion range. Murakami also designed Hamilton's helmet for that year's Suzuka Grand Prix . In June 2024, Murakami collaborated with k-pop group NewJeans to create exclusive merchandise and album designs for their Japanese debut single " Supernatural ". In November 2024, Murakami designed

12998-463: The projectile rings that were slid over a 1-inch rod. This rod then extended forward through the tungsten carbide plug, impact-absorbing anvil, and nose plug backstop, eventually protruding out of the front of the bomb casing. This entire target assembly was secured at both ends with locknuts. When the hollow-front projectile reached the target and slid over the target insert, the assembled super-critical mass of uranium would be completely surrounded by

13132-405: The projectile slug was pushed 42 inches (1,100 mm) along the 72-inch-long (1,800 mm), 6.5-inch-wide (170 mm) smooth-bore gun barrel. The slug "insert" was a 4-inch cylinder, 7 inches in length with a 1-inch (25 mm) axial hole. The slug comprised 40% of the total fissile mass (25.6 kilograms or 56 pounds). The insert was a stack of six washer-like uranium discs somewhat thicker than

13266-491: The range of the 5 pounds per square inch (34 kPa) overpressure damage expected from a detonated 12 kiloton weapon with a height of burst at 1,968 feet (600 m) would be expected to be 0.98 miles (1.58 km), whereas a 20 kiloton weapon would have the same range extend to 1.12 miles (1.80 km), a difference of only 0.14 miles (0.23 km). The areas affected for each would be 3.02 square miles (7.8 km ) and 3.91 square miles (10.1 km ), respectively. As such,

13400-406: The realm of contemporary art, despite large audiences for exhibitions. Art critic Peter Timms has said that attention is drawn to the way that craft objects must subscribe to particular values in order to be admitted to the realm of contemporary art. "A ceramic object that is intended as a subversive comment on the nature of beauty is more likely to fit the definition of contemporary art than one that

13534-546: The rigid and pretentious Western hierarchy of "high art." In the West, it certainly is dangerous to blend the two because people will throw all sorts of stones. But that's okay—I'm ready with my hard hat. Murakami has also collaborated with a wide range of creators and industries in Japan, a prominent example being the image characters he created for the press relations campaign of the major urban real estate development Roppongi Hills . In 2009, music producer Pharrell Williams unveiled

13668-410: The same target area: "220 B-29s carrying 1.2 kilotons of incendiary bombs , 400 tons of high-explosive bombs, and 500 tons of anti-personnel fragmentation bombs ." Since the target was spread across a two-dimensional plane, the vertical component of a single spherical nuclear explosion was largely wasted. A cluster bomb pattern of smaller explosions would have been a more energy-efficient match to

13802-500: The scientists working on bomb design during the Manhattan Project . In 1942, it was not yet known which of the two fissile materials pathways being simultaneously pursued— uranium-235 or plutonium-239 —would be successful, or if there were significant differences between the two fuels that would impact the design work. Coordination with British scientists in May 1942 convinced the American scientists, led by J. Robert Oppenheimer , that

13936-464: The severe destruction region. The first effect of the explosion was blinding light, accompanied by radiant heat from the fireball. The Hiroshima fireball was 1,200 feet (370 m) in diameter, with a surface temperature of 10,000 °F (6,000 °C), about the same temperature as at the surface of the sun. Near ground zero, everything flammable burst into flame. One famous, anonymous Hiroshima victim, sitting on stone steps 850 feet (260 m) from

14070-479: The speed of sound, analogous to thunder generated by lightning. Knowledge about urban blast destruction is based largely on studies of Little Boy at Hiroshima. Nagasaki buildings suffered similar damage at similar distances, but the Nagasaki bomb detonated 2.0 miles (3.2 km) from the city center over hilly terrain that was partially bare of buildings. In Hiroshima, almost everything within 1.0 mile (1.6 km) of

14204-407: The state of contemporary art in Japan, believing it to be "a deep appropriation of Western trends." Thus, much of his early work was done in the spirit of social criticism and satire . On an article naming and explaining all of Murakami's pieces lies the infamous My Lonesome Cowboy , a companion to his earlier Hiropon . The sculpture is that of a naked anime character with blond spiky hair with

14338-400: The supercritical mass, which was fired onto the smaller group, with four polonium-beryllium neutron initiators to make the supercritical mass explode. A hole in the center of the larger piece dispersed the mass and increased the surface area, allowing more fission neutrons to escape, thus preventing a premature chain reaction. But, for this larger, hollow piece to have minimal contact with

14472-505: The survivors' children. After the surrender of Japan was finalized, Manhattan Project scientists began to immediately survey the city of Hiroshima to better understand the damage, and to communicate with Japanese physicians about radiation effects in particular. The collaboration became the Atomic Bomb Casualty Commission in 1946, a joint U.S.–Japanese project to track radiation injuries among survivors. In 1975 its work

14606-511: The target. When the war ended, it was not expected that the inefficient Little Boy design would ever again be required, and many plans and diagrams were destroyed. However, by mid-1946 the Hanford Site reactors were suffering badly from the Wigner effect . Faced with the prospect of no more plutonium for new cores and no more polonium for the initiators for the cores that had already been produced,

14740-520: The term were founded in the 1930s, such as in 1938 the Contemporary Art Society of Adelaide , Australia , and an increasing number after 1945. Many, like the Institute of Contemporary Art, Boston changed their names from ones using "modern art" in this period, as Modernism became defined as a historical art movement , and much "modern" art ceased to be "contemporary". The definition of what

14874-524: The terms modern art and contemporary art by non-specialists. The classification of "contemporary art" as a special type of art, rather than a general adjectival phrase, goes back to the beginnings of Modernism in the English-speaking world. In London , the Contemporary Art Society was founded in 1910 by the critic Roger Fry and others, as a private society for buying works of art to place in public museums. A number of other institutions using

15008-399: The time of the bombing, 6,789 were killed or missing as a result of the bombing. The exact measurement of the explosive yield of the bomb was problematic since the weapon had never been tested. President Harry S. Truman officially announced that the yield was 20 kilotons of TNT (84 TJ). This was based on Parsons's visual assessment that the blast was greater than what he had seen at

15142-413: The tungsten carbide tamper , it must be the projectile, since only the projectile's back end was in contact with the tamper prior to detonation. The rest of the tungsten carbide tamper surrounded the sub-critical mass target cylinder (called the "insert" by the designers) with air space between it and the insert. This arrangement packs the maximum amount of fissile material into a gun-assembly design. For

15276-468: The very notion of an artwork . She regards Duchamp 's Fountain (which was made in the 1910s in the midst of the triumph of modern art) as the starting point of contemporary art, which gained momentum after World War II with Gutai 's performances, Yves Klein 's monochromes and Rauschenberg 's Erased de Kooning Drawing . Contemporary artwork is characterised by diversity: diversity of material, of form, of subject matter, and even time periods. It

15410-405: The weapon to detonate. If immersed in water, the uranium components were subject to a neutron moderator effect, which would not cause an explosion but would release radioactive contamination . For this reason, pilots were advised to crash on land rather than at sea. Ultimately, Parsons opted to keep the explosives out of the Little Boy bomb until after the B-29 had taken off, to avoid the risk of

15544-466: The weapon to fit into a B-29 bomb bay without difficulty. Though not an optimal use of fissile material compared to the implosion design, it was seen as a nearly guaranteed weapon. The design specifications were completed in February 1945, and contracts were let to build the components. Three different plants were used so that no one would have a copy of the complete design. The gun and breech were made by

15678-480: The work to Naval Captain William Sterling Parsons , who, along with Ed McMillan , Charles Critchfield , and Joseph Hirschfelder would be responsible for rendering the theory into practice. Concern that impurities in reactor-bred plutonium would make predetonation more likely meant that much of the gun-design work was focused on the plutonium gun. To achieve high projectile velocities, the plutonium gun

15812-527: The yield at the time. More rigorous estimates of the bomb yield and conventional bomb equivalent were made when more data was acquired following the end of the war. A 1985 study estimated the bomb's yield was around 15 kilotons of TNT (63 TJ). After being selected in April 1945, Hiroshima was spared conventional bombing to serve as a pristine target, where the effects of a nuclear bomb on an undamaged city could be observed. While damage could be studied later,

15946-481: The yield was estimated in the 1960s at 16.6 ± 0.3 kilotons. A review conducted by a scientist at Los Alamos in 1985 concluded, on the basis of existing blast, thermal, and radiological data, and then-current models of weapons effects, that the best estimate of the yield was 15 kilotons of TNT (63 TJ) with an uncertainty of 20% (±3 kt). By comparison, the best value for the Nagasaki bomb was evaluated as 21 kilotons of TNT (88 TJ) with an uncertainty of 10% (±2 kt),

16080-592: Was 17 feet (5.2 m) long with a narrow diameter (suggesting its codename as the Thin Man) which created considerable difficulty in its ballistics dropping from aircraft and fitting it into the bomb bay of a B-29. In early 1944, Emilio G. Segrè and his P-5 Group at Los Alamos received the first samples of plutonium produced from a nuclear reactor, the X-10 Graphite Reactor at Clinton Engineer Works in Oak Ridge, Tennessee . Analyzing it, they discovered that

16214-460: Was already well underway in the 20th century. Diverse and eclectic, contemporary art as a whole is distinguished by the very lack of a uniform, organising principle, ideology, or " -ism ". Contemporary art is part of a cultural dialogue that concerns larger contextual frameworks such as personal and cultural identity, family, community, and nationality. In English, modern and contemporary are synonyms , resulting in some conflation and confusion of

16348-451: Was borrowed from a critic in the late 17th century who used it to describe the paintings of Eitoku Kano . Kaikai Kiki executes Murakami's wide range of artistic endeavors and consists of both offices and production studios. In addition to handling the production and promotion of Murakami's artwork and projects, the company manages the careers of young artists, organizes international art projects, produces and promotes merchandise, and handles

16482-468: Was conducted with L-1 on 23 July 1945. It was dropped over the sea near Tinian in order to test the radar altimeter by the B-29 later known as Big Stink , piloted by Colonel Paul W. Tibbets , the commander of the 509th Composite Group . Two more drop tests over the sea were made on 24 and 25 July, using the L-2 and L-5 units in order to test all components. Tibbets was the pilot for both missions, but this time

16616-692: Was created in 2001 is said to show the "otaku culture and its strange, shocking sexuality in full force". The concept of the smiling flowers was revealed in an interview to be "evoked repressed, contradictory emotions and collective trauma of Japanese locals triggered by the Hiroshima and Nagasaki bombings back in 1945." In addition to large paintings such as 727 (permanent collection Museum of Modern Art, New York) and Tan Tan Bo Puking – a.k.a. Gero Tan, he has also produced sculptures, balloons, 'all-over' wallpaper installations, animated works, prints, posters, and assorted merchandise. Murakami has expressed since early on

16750-449: Was established by March 1943, with expertise provided by E.L. Rose , an experienced gun designer and engineer. Work was begun to study the properties of barrels, internal and external ballistics , and tampers of gun weapons. Oppenheimer led aspects of the effort, telling Rose that "at the present time [May 1945] our estimates are so ill founded that I think it better for me to take responsibility for putting them forward." He soon delegated

16884-529: Was exposed to and highly inspired by Western contemporary artists such as Anselm Kiefer and especially the simulationism of artists such as Jeff Koons . He established a small studio, which, together with the Hiropon Factory in Japan, became the precursor to his company Kaikai Kiki. After returning to Japan, he would develop the core concepts behind his artistic practice and begin exhibiting regularly at major galleries and institutions across Europe and America. In 2000, Murakami published his " Superflat " theory in

17018-682: Was involved in NFTs from April 2021 but his first project, "Murakami.Flowers", was suspended by the artist shortly after its release due to his concern about his little knowledge of the topic. The idea of creating NFTs stemmed from his financial problems during the beginning of the COVID-19 pandemic . In November 2021 he collaborated with Nike -owned company RTFKT Studios on CloneX avatar projects. In January 2022 he announced resuming work on "Murakami.Flowers". Contemporary art Art of East Asia Art of South Asia Art of Southeast Asia Art of Europe Art of Africa Art of

17152-475: Was roughly 2.0 miles (3.2 km) in diameter, corresponding closely to the severe blast-damage zone. (See the USSBS map, right.) Blast-damaged buildings provided fuel for the fire. Structural lumber and furniture were splintered and scattered about. Debris-choked roads obstructed firefighters. Broken gas pipes fueled the fire, and broken water pipes rendered hydrants useless. At Nagasaki, the fires failed to merge into

17286-465: Was round and fat so it was named after Kasper Gutman, a rotund character in Hammett's 1930 novel The Maltese Falcon , played by Sydney Greenstreet in the 1941 film version . Little Boy was named by others as an allusion to Thin Man since it was based on its design. It was also sometimes referred to as the "Mark I" nuclear bomb design, with "Mark II" referring to the abandoned Thin Man, and "Mark III" to

17420-479: Was sent to Hiroshima to evaluate the effects of the blast. From evaluating the effects on objects and structures, Penney concluded that the yield was 12 ± 1 kilotons. Later calculations based on charring pointed to a yield of 13 to 14 kilotons. In 1953, Frederick Reines calculated the yield as 15 kilotons of TNT (63 TJ). Based on the Project Ichiban data, and the pressure-wave data from The Great Artiste ,

17554-499: Was superseded by the Radiation Effects Research Foundation . In 1962, scientists at Los Alamos created a mockup of Little Boy known as "Project Ichiban" in order to answer some of the unanswered questions about the exact radiation output of the bomb, which would be useful for setting benchmarks for interpreting the relationship between radiation exposure and later health outcomes. But it failed to clear up all

17688-550: Was supplied for the bombs. By early 1947, the problem caused by the Wigner effect was on its way to solution, and the three officers were reassigned. The Navy Bureau of Ordnance began in 1947 to produce 25 "revised" Little Boy mechanical assemblies for use by the nuclear-capable Lockheed P2V Neptune aircraft carrier aircraft (which could be launched from, but not land on, the Midway -class aircraft carriers ). Components were produced by

17822-500: Was the founder and organizer of the biannual art fair Geisai. Murakami was born and raised in Tokyo , Japan. From early on, he was a fan of anime and manga (Japanese cartoons and comics respectively), and hoped to work in the animation industry. He attended Tokyo University of the Arts to acquire the drafting skills necessary to become an animator, but eventually majored in Nihonga ,

17956-450: Was then fully armed. Jeppson monitored the bomb's circuits. The bomb was dropped at approximately 08:15 (JST) on 6 August 1945. After falling for 44.4 seconds, the time and barometric triggers started the firing mechanism. The detonation happened at an altitude of 1,968 ± 50 feet (600 ± 15 m). It was less powerful than the Fat Man , which was dropped on Nagasaki , but
