New paint colors invented by neural network

fieldbears:

So if you’ve ever picked out paint, you know that every infinitesimally different shade of blue, beige, and gray has its own descriptive, attractive name. Tuscan sunrise, blushing pear, Tradewind, etc… There are in fact people who invent these names for a living. But given that the human eye can see millions of distinct colors, sooner or later we’re going to run out of good names. Can AI help?

For this experiment, I gave the neural network a list of about 7,700 Sherwin-Williams paint colors along with their RGB values. (RGB = red, green, and blue color values) Could the neural network learn to invent new paint colors and give them attractive names?

One way I have of checking on the neural network’s progress during training is to ask it to produce some output using the lowest-creativity setting. Then the neural network plays it safe, and we can get an idea of what it has learned for sure.

By the first checkpoint, the neural network has learned to produce valid RGB values - these are colors, all right, and you could technically paint your walls with them. It’s a little farther behind the curve on the names, although it does seem to be attempting a combination of the colors brown, blue, and gray.

By the second checkpoint, the neural network can properly spell green and gray. It doesn’t seem to actually know what color they are, however.

Let’s check in with what the more-creative setting is producing.

…oh, okay.

Later in the training process, the neural network is about as well-trained as it’s going to be (perhaps with different parameters, it could have done a bit better - a lot of neural network training involves choosing the right training parameters). By this point, it’s able to figure out some of the basic colors, like white, red, and grey:

Although not reliably.

In fact, looking at the neural network’s output as a whole, it is evident that:

  1. The neural network really likes brown, beige, and grey.
  2. The neural network has really really bad ideas for paint names.

New Elaborate Patterns and Designs Carved on Produce by ‘Gaku’

Although we first mentioned his work here only a month ago, food artist Gaku has continues to share numerous examples of his inventive approach to food carving called mukimono. Gaku works with little more than an x-acto knife to carve quickly before the fruit or vegetable starts to change color, executing motifs and patterns often found in Japanese art. You can see even more of his latest works on Instagram.

Creating The Never-Ending Bloom: The Amazing Mathematical Wonders of John Edmark

We’ve long marveled at artist John Edmark's (previously) kinetic objects that function as a medium to express a variety of mathematical formulas and concepts. The spiral-like sculptures often defy description and even when looking at them it’s hard to understand how they work, something he refers to as “instruments that amplify our awareness of the sometimes tenuous relationship between facts and perception.” The folks at SciFri recently visited with Edmark in his studio to learn more about how he works and to catch a glimpse of some rather unusual sculptures he’s created over the last few years.

If you find a bunch of bones that are A: untouched and B: supernaturally clean, there is definitely a reason for both of those things. Sometimes that reason is ants. Sometimes those ants are fire ants. Sometimes those fire ants have made a nest over the entire three meter area around those bones

"Emergency Alert" Declared At Hanford Nuclear Facility In Washington, Evacuation Ordered

Hanford ist eine der gruseligeren Atom-Altlasten der USA. Das liegt in Washington State, der Columbia River fließt dort vorbei und mündet bei Portland, Oregon, in den Pazifik.

Praktisch alle Meldungen zu Hanford sind sehr apokalyptisch, z.B. US-Strahlenruine Hanford - Amerikas atomare Zeitbombe.

Nicht Tsunami, sondern Beben soll AKW ruiniert haben


Schlechte Nachrichten für AKW-Betreiber: Ein Insider macht die Erdstöße vom 11. März für schwere Schäden am AKW in Fukushima verantwortlich - die Betreiberfirma gab bislang dem Tsunami die Schuld am GAU. Damit wachsen Zweifel an der Erdbebensicherheit von Atomkraftwerken weltweit. 

Es müssen gruselige Szenen gewesen sein im ersten Block des AKW Fukushima-Daiichi in der Nacht nach dem Erdbeben vom 11. März: Mitarbeiter der Betreiberfirma Tepco betreten das Reaktorgebäude, um die Schäden zu beurteilen. Doch kaum passieren sie die Sicherheitstür, schlagen ihre Dosimeter Alarm. Die Techniker evakuieren sofort. Ihre Vermutung: Das Gebäude ist mit radioaktivem Dampf gefüllt. Ausgehend von Dosimeter-Daten schätzen Experten später, dass die Strahlung in dem Gebäude bei etwa 300 Millisievert pro Stunde gelegen hat - ein hoher Wert, der einen Austritt großer Mengen radioaktiven Materials in dem Reaktor vermuten lasse. 

Diesen Ablauf hat eine nicht genannte Quelle aus dem Unternehmen Tokyo Electric Power Company (Tepco) der japanischen Nachrichtenagentur Kyodo geschildert. Die Aussage erhärtet einen Verdacht, den Experten schon bald nach der Katastrophe äußerten: Der Schaden an Reaktor 1 ist nicht erst mit dem Ausfall der Kühlung nach dem Tsunami entstanden, sondern bereits mit dem Erdbeben. Die Atomanlage hätte den Erschütterungen nicht standgehalten.

Das würde nicht nur bedeuten, dass Tepco von Anfang an die Unwahrheit über den Unfallhergang verbreitet hätte. Es würde auch der internationalen Nuklearindustrie einen Strich durch die Rechnung machen: Die hatte immer wieder betont, das Unglück sei ausschließlich vom Tsunami verursacht worden. Da weltweit nur die wenigsten Atomkraftwerke in Tsunami-Gegenden liegen, sei die Kernenergie durch die Ereignisse in Fukushima nicht gefährdet. Auch in Deutschland liegen AKW in Erdbebengebieten, das Bebenrisiko ist gleichwohl schlechter bekannt als angenommen.

Zweifel von Anfang an

Die offizielle Version zu den Ereignissen in Fukushima lautete bislang: Das Erdbeben hätten die Reaktoren ausgezeichnet überstanden. Doch dann sei der Tsunami gekommen und hätte die Stromversorgung für die Kühlung außer Kraft gesetzt. Dadurch sei die Notstromversorgung angesprungen. Erst als sich deren Batterien leerten, entstanden sukzessive die Probleme, weil die Brennelemente dann nicht mehr gekühlt wurden.

Doch die Schilderungen, die nun aus der Betreiberfirma an die Presse gesteckt wurden, nähren Zweifel an dieser offiziellen Version. "Schon das Erdbeben könnte den Reaktordruckbehälter oder die daran angeschlossenen Rohre beschädigt haben", sagte der Tepco-Mitarbeiter der Nachrichtenagentur Kyodo. Wie sonst hätte die Radioaktivität aus dem Kern bis zum Abend ins Reaktorgebäude gelangen können - wie es die Dosimeter der Arbeiter schon in der Nacht angezeigt hätten?

Bereits Ende März hatte der Ingenieur Mitsuhiko Tanaka auf einer Pressekonferenz den Verdacht geäußert, in Block 1 habe es gleich nach dem Erdbeben einen Kühlwasserverlust gegeben. Tanaka, der früher für Babcock Hitachi gearbeitet hat und am Design für den Druckbehälter des Reaktors 4 in Fukushima beteiligt war, stützte seine These vom frühen Kühlwasserverlust auf Daten aus dem Reaktor 1. Danach hatten die Betreiber am 11. März um 16.36 Uhr - knapp zwei Stunden nach dem Erdbeben - versucht, das Notkühlsystem einzusetzen. Das reguläre System war zu diesem Zeitpunkt bereits ausgefallen. Auch die Notkühlung funktionierte nicht. Angeblich als Folge des Tsunamis.

Tanaka allerdings kam zu einem ganz anderen Schluss - der zu den jetzt bekannt gewordenen Schilderungen des Insiders passt. Tanaka rechnete vor: Die ersten verfügbaren Messdaten aus Reaktor 1 beschreiben dessen Zustand zwölf Stunden nach dem Erdbeben. Im Reaktordruckbehälter, in dem sich der Kernbrennstoff befindet, war der Druck von den üblichen 7 Megapascal (das entspricht 70 bar; ein Autoreifen wird mit etwa 2 bar gefüllt) auf nur noch 0,8 Megapascal gesunken. Gleichzeitig, erklärt Tanaka, "sank der Kühlwasserpegel dort rapide". Im Sicherheitsbehälter dagegen, der den Druckbehälter umgibt, stieg parallel der Druck an, von 0,1 auf 0,8 Megapascal.

Diese Druckveränderungen sind für Tanaka ein Hinweis für ein Leck im Kühlsystem. Es sei, kommentierte er, aufgrund dieser Daten "nahezu unbestreitbar", dass es einen Kühlwasserverlust gegeben habe. Eine Analyse, die die gleich nach dem Erdbeben gemessenen, erhöhten Strahlungswerte erklären würde.

Tanaka vermutete, dass es einen Rohrbruch am Reaktordruckbehälter gegeben habe. Der wiederum hätte nichts mit dem Tsunami zu tun gehabt. Er könne nur durch das Erdbeben entstanden sein. Viele Experten hätten dass wissen müssen oder wissen können, sagt Tanaka: "Aber sie haben geschwiegen".

Mit dem Versagen der Notkühlung war das wichtigste Instrument der Betreiber im Kampf um die Eindämmung der Katastrophe ausgefallen. Der Reaktor war damit von Beginn an außer Kontrolle.

Sollten sich die Analyse des Experten Tanaka und die Aussage des Tepco-Insiders bestätigen, wäre klar: Die Konstruktion von Reaktorblock 1 hat dem Erdbeben nicht standgehalten. Das hätte Konsequenzen für die Kraftwerksbetreiber weltweit. Denn im Gegensatz zum Tsunamirisiko besteht Erdbebengefahr an vielen Orten.

Germany Breaks Record: 85% of Energy Comes From Renewables Last Weekend


Germany's "Energiewende"—the country's low-carbon energy revolution—turned another successful corner last weekend when renewable energy sources nearly stamped out coal and nuclear.


Bild könnte enthalten: Himmel, Wolken, im Freien und Natur


Thanks to a particularly breezy and sunny Sunday, renewables such as wind and solar, along with some biomass and hydropower, peaked at a record 85 percent, or 55.2 gigawatts, and even came along with negative prices for several hours at the electricity exchange.

Conversely, coal use was at an all-time minimum. According to DW, on April 30, coal-fired power stations were only operational between 3 and 4 p.m. and produced less than eight gigawatts of energy, well below the maximum output of about 50 gigawatts.

"Most of Germany's coal-fired power stations were not even operating on Sunday, April 30th," Patrick Graichen of Agora Energiewende told RenewEconomy. "Nuclear power sources, which are planned to be completely phased out by 2022, were also severely reduced."

Graichen added that days like Sunday would be "completely normal" by 2030 thanks to the government's continued investment in the Energiewende initiative.

Following the Fukushima disaster in Japan, Germany announced in May 2011 that it plans to phase out nuclear and shut down all its nuclear power plants by 2022. That Sunday, nuclear power plants reduced their output from 7.9 to 5 gigawatts.

Germany's ambitious energy transition aims for at least an 80 percent share of renewables by 2050, with intermediate targets of 35 to 40 percent share by 2025 and 55 to 60 percent by 2035.

Fukushima a “ticking time bomb” — Fires now “raging” near nuclear plant — Blaze doubles in size; “Smoke rising from wide areas” — Concern over fallout of highly radioactive material; Officials closely watching radiation levels


A wildfire has been raging for more than 2 days near the damaged Fukushima Daiichi nuclear power plant… The area is part of a zone designated as “no-entry” due to high radiation levels… Fukushima and Miyagi prefectures and the Self-Defense Forces are using helicopters to fight the blaze. They are also looking at the possibility of using ground crews. Footage from an NHK helicopter on Monday morning showed smoke rising from wide areas and fires burning in several locations

Mainichi, May 1, 2017: Wildfire rages in highly radioactive Fukushima mountain forest — A fire broke out in a mountain forest near the crippled Fukushima No. 1 Nuclear Power Plant on the evening of April 29, consuming an area approximately 20 hectares in size, according to prefectural authorities… As the fire continued to spread, however, helicopters from the GSDF, Fukushima Prefecture and other parties on May 1 resumed fire extinguishing operations from around 5 a.m. … As of May 1, there were no major changes to radiation levels in the heart of Namie and other areas near the fire scene, according to the Ministry of the Environment. “We will continue to closely watch changes in radiation doses in the surrounding areas,” said a ministry official.

Common Dreams, May 1, 2017: Sparking Fears of Airborne Radiation, Wildfire Burns in Fukushima ‘No-Go Zone’; Contaminated forests such as those outside fallout sites like Fukushima and Chernobyl ‘are ticking time bombs’ — A wildfire broke out in the highly radioactive “no-go zone” near the crippled Fukushima nuclear power plant over the weekend, reviving concerns over potential airborne radiation… Local officials were forced to call in the Japanese military… In a blog post last year, Anton Beneslavsky, a member of Greenpeace Russia’s firefighting group who has been deployed to fight blazes in nuclear Chernobyl, outlined the specific dangers of wildfires in contaminated areas. “During a fire, radionuclides like caesium-137, strontium-90 and plutonium rise into the air and travel with the wind,” Beneslavsky wrote. “This is a health concern because when these unstable atoms are inhaled, people become internally exposed to radiation.” Contaminated forests such as those outside fallout sites like Fukushima and Chernobyl “are ticking time bombs,” scientist and former regional government official Ludmila Komogortseva told Beneslavsky. “Woods and peat accumulate radiation,” she explained “and every moment, every grass burning, every dropped cigarette or camp fire can spark a new disaster.”

Sputnik News, May 1, 2017: Japanese Authorities Fighting Wildfire in Evacuation Zone Near Fukushima NPP… There were no reports either about the wind direction or the changes in the background radiation level in relation to the fire.
