Impossible Colors and How to See Them

How Impossible Colors Work Basically, the human eye has three types of cone cells that register color that work in an antagonistic fashion:Blue versus yellowRed versus greenLight versus darkThere is overlap between the wavelengths of light covered by the cone cells, so you see more than just blue, yellow, red, and green. White, for example, is not a wavelength of light, yet the human eye perceives it as a mixture of different spectral colors. Because of the opponent process, you can't see both blue and yellow at the same time, nor red and green. These combinations are so-called impossible colors.

Chimerical Colors Hyperbolic colors may be seen by staring at a color and then viewing the afterimage on the complementary color opposite it on the color wheel. Dave King / Getty Images

Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.

Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.

On Thursday, the FBI arrested three men, Patrik J. Mathews, 27, Brian M. Lemley Jr., 33, and William G. Bilbrough IV, 19, with firearms charges, and they had plans, an official said, to attend a Virginia pro-gun rally. This followed Virginia Gov. Ralph Northam's declaration of a temporary state of emergency after authorities learned that extremists hoped to use the anti-gun control rally planned next Monday -- Martin Luther King, Jr. Day -- to incite a violent clash.

These arrests add to mounting evidence that a decades-old and violent white-power movement is alive and well, perhaps even gaining strength. White power is a social movement that has united neo-Nazis, Klansmen, skinheads, and militiamen around a shared fear of racial annihilation and cultural change. Since 1983, when movement leaders declared war on the federal government, members of such groups have worked together to bring about a race war.

In technical terms, the Great Red Spot is an anticyclonic storm lying in a high-pressure zone high in Jupiter's clouds. It rotates counter-clockwise and takes about six Earth days to make one complete trip around the planet. It has clouds embedded within it, which often tower many kilometers above the surrounding cloud decks. Jet streams to its north and south help keep the spot at the same latitude as it circulates.

Observers have studied the gas giant planet Jupiter since antiquity. However, they've only been able to observe such a giant spot for a few centuries since it was first discovered. Ground-based observations allowed scientists to chart the motions of the spot, but a true understanding was only made possible by spacecraft flybys. The Voyager 1 spacecraft raced by in 1979 and sent back the first close-up image of the spot. Voyager 2, Galileo, and Juno also provided images.

Scientists have been able to measure the spot's depth using specialized instruments on the Juno spacecraft. It appears to be some 300 kilometers deep. That's much deeper than any of Earth's oceans, the deepest of which is just over 10 kilometers. Interestingly, the "roots" of the Great Red Spot are warmer at the bottom (or the base) than at the top. This warmth feeds the incredibly strong and fast winds at the top of the spot, which can blow more than 430 kilometers per hour. Warm winds feeding a strong storm is a well-understood phenomenon on Earth, particularly in massive hurricanes. Above the cloud, temperatures rise again, and scientists are working to understand why this is happening. In that sense, then, the Great Red Spot is a Jupiter-style hurricane.

Anyone with normal color vision agrees that blood is roughly the same color as strawberries, cardinals and the planet Mars. That is, they're all red. But could it be that what you call "red" is someone else's "blue"?

It’s a question that everyone has pondered at one time or another: does everyone view colors in the same way?

. But among the rest of us with normal color vision, can we ever be sure we’re seeing exactly the same thing?

combines two distinct approaches adopted by states where red flag laws already exist.

In interviews across three German states, historians, activists, officials and ordinary citizens explained their support for monuments glorifying a former enemy and occupier as a mixture of bureaucratic drift, aversion to change and a rock-solid commitment to honoring the victims of Nazi aggression that trumps any shifts in global affairs.

“We were taught to learn from pain,” said Teresa Schneidewind, 33, the head of Lützen’s museum. “We care for our memorials, because they allow us to learn from the mistakes of past generations.”

Germany’s top court ruled just last year against the removal of a medieval, antisemitic sculpture in the very church where Martin Luther had preached. Despite debates, some swastikas from the Third Reich have been left on church bells.

Incels (as they’re known) are infamous for sharing misogynistic attitudes and bitter hostility toward the romantically successful

somehow, incels’ hateful rhetoric has bizarrely become popularized via Gen Z slang.

it’s common to hear the suffix “pilled” as a funny way to say “convinced into a lifestyle.” Instead of “I now love eating burritos,” for instance, one might say, “I’m so burritopilled.” “Pilled” as a suffix comes from a scene in 1999’s “The Matrix” where Neo (Keanu Reeves) had to choose between the red pill and the blue pill, but the modern sense is formed through analogy with “blackpilled,” an online slang term meaning “accepting incel ideology.

About 30 percent of heart attacks, strokes and deaths from heart disease can be prevented in people at high risk if they switch to a Mediterranean diet rich in olive oil, nuts, beans, fish, fruits and vegetables, and even drink wine with meals, a large and rigorous new study has found.

The magnitude of the diet’s benefits startled experts. The study ended early, after almost five years, because the results were so clear it was considered unethical to continue.

The diet helped those following it even though they did not lose weight

The two concepts are usually seen in complete opposition in our political discourse. The more capitalism and wealth, the familiar argument goes, the better able we are to do without a safety net for the poor, elderly, sick and young. And that’s true

the cultural contradictions of capitalism, brilliantly explained in Daniel Bell’s classic volume, are indeed contradictions. The turbulence of a growing wealth-creating free market disrupts traditional ways of life like no other. Even in a culture like ours used to relying from its very origins on entrepreneurial spirit, the dislocations are manifold. People have to move; their choices of partners for love and sex multiply; families disaggregate on their own virtual devices; grandparents are assigned to assisted living; second marriages are as familiar as first ones; and whole industries – and all the learned skills that went with them – can just disappear overnight

Capitalism is in this sense anti-conservative. It is a disruptive, culturally revolutionary force through human society. It has changed the world in three centuries more than at any time in the two hundred millennia that humans have lived on the earth. This must leave – and has surely left – victims behind. Which is why the welfare state emerged. The sheer cruelty of the market, the way it dispenses brutally with inefficiency (i.e. human beings and their jobs), the manner in which it encourages constant travel and communication: these, as Bell noted, are not ways to strengthen existing social norms, buttress the family, allow the civil society to do what it once did: take care of people within smaller familial units according to generational justice and respect. That kind of social order – the ultimate conservative utopia – is inimical to the capitalist enterprise

At the time, no one really knew who was for or against the revolution.

What did satisfy Haidt’s natural thirst for understanding human beings was social psychology.

Haidt initially found moral psychology “really dull.” He described it to me as “really missing the heart of the matter and too cerebral.” This changed in his second year after he took a course from the anthropologist Allen Fiske and got interested in moral emotions.

“The Emotional Dog and its Rational Trail,” which he describes as “the most important article I’ve ever written.”

democratization of information-gathering—when accompanied by smart institutional and technological arrangements—has been tremendously useful, giving us Wikipedia and Twitter. But it has also spawned thousands of sites that undermine scientific consensus, overturn well-established facts, and promote conspiracy theories

Meanwhile, the move toward social search may further insulate regular visitors to such sites; discovering even more links found by their equally paranoid friends will hardly enlighten them.

Initially, the Internet helped them find and recruit like-minded individuals and promote events and petitions favorable to their causes. However, as so much of our public life has shifted online, they have branched out into manipulating search engines, editing Wikipedia entries, harassing scientists who oppose whatever pet theory they happen to believe in, and amassing digitized scraps of "evidence" that they proudly present to potential recruits.

I think this is one of the most burning issues around art – how do we tell if something is good? And who tells us that it’s good?

many of the methods of judging are very problematic and many of the criteria used to assess art are conflicting. We have financial value, popularity, art historical significance, or aesthetic sophistication. All these things could be at odds with each other.

A visitor to an exhibition like the Hockney one, if they were judging the quality of the art, might use a word like “beauty”. Now, if you use that kind of word in the art world, be very careful. There will be sucking of teeth and mournful shaking of heads because their hero, the artist Marcel Duchamp, of “urinal” fame, he said, “Aesthetic delectation is the danger to be avoided.” In the art world sometimes it can feel as if to judge something on its beauty, on its aesthetic merits, is as if you’re buying into something politically incorrect, into sexism, into racism, colonialism, class privilege. It almost feels it’s loaded, because where does our idea of beauty come from?

If you’ve taken to the United States streets anytime lately, you may have noticed that most public school buses are a very particular shade of yellow. That shade is called National School Bus Glossy Yellow in Canada and the US, and it was specially designed by Dr. Frank Cyr.

Yellow is easy to see in the dim lights of early morning or late evening, and because it's seen across both the green and red cones in the eye, it pops in our vision faster than other colors.

What’s more, while the majority of those who are color blind have trouble distinguishing red from green, they can still see yellow just fine.

Rosenstein belongs to a small but growing band of Silicon Valley heretics who complain about the rise of the so-called “attention economy”: an internet shaped around the demands of an advertising economy.

“It is very common,” Rosenstein says, “for humans to develop things with the best of intentions and for them to have unintended, negative consequences.”

Expert judges and amateurs alike claim to judge classical musicians based on sound. But Tsay’s research suggests that the original judges, despite their experience and expertise, judged the competition (which they heard and watched live) based on visual information, just as amateurs do.

just like with classical music, we do not appraise wine in the way that we expect. 

Priceonomics revisited this seemingly damning research: the lack of correlation between wine enjoyment and price in blind tastings, the oenology students tricked by red food dye into describing a white wine like a red, a distribution of medals at tastings equivalent to what one would expect from pure chance, the grand crus described like cheap wines and vice-versa when the bottles are switched.
