What is it like to see at bat?

“I see spin. I don’t see color. I don’t see red,” he said before a game with the Blue Jays. He thought for a second, though. “Maybe I do and I don’t think I do.” What can hitters actually see out of a pitcher's hand?

Which is bigger: >---<

Optical illusions are not universal, and the differences in how we perceive them can help us to understand cognition. The famous Müller-Lyer illusion is not universal, but differs by culture, with some African tribes unable to see the illusion at all - possibly because of differences in environment. Individuals with autism seem less sensitive to the Sheppard's table illusion, which might help improve an understanding of the condition. Differences in responses are possible because different illusions trick your brain in different ways. BBC has a great history of the evolution of optical illusions, and, finally, here are some auto-kinectic illusions, because they are awesome.

“the ideal often clashes violently with the truth”

Visual Literacy in the Age of Open Content by Allana Mayer [JSTOR]
We have similar stories all throughout history: the moment when a perception—whether a literal way of seeing or a figurative mode of thinking—is assaulted and fundamentally shifts, a non-reversible alteration, a displacement from one’s old ways. Western society has seen plenty of moments like these, moments where a perceptive or critical threshold has been crossed.

Nature's Perfect Killing Machine Can Be Killed With Soap

Ebola is nightmare fuel: a biological doomsday device conspiring with our bodies to murder us in uniquely gruesome fashion. It’s also killed fewer than 2,000 people.

I Can Tell By The Pixels

Visualizing Algorithms shows you how computer algorithms can be represented visually, leading to better understanding of how the algorithms work:

"Have you ever implemented an algorithm based on formal description? It can be hard! Being able to see what your code is doing can boost productivity. Visualization does not supplant the need for tests, but tests are useful primarily for detecting failure and not explaining it. Visualization can also discover unexpected behavior in your implementation, even when the output looks correct."

When to Separate the Art From the Artist

Controversy about Woody Allen is in the news again due to an open letter by Dylan Farrow, who explicitly details sexual abuse allegedly committed by Allen when Farrow was seven. The letter appeared shortly after Allen was awarded the Cecil B. DeMille Award for Lifetime Achievement, prompting the old question, is it possible to separate the person from the art and if so, how?

Why Should Engineers and Scientists Be Worried About Color?

At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data.

Achilles sat on the shore and looked out to the wine-dark sea

That Homer used the epithet "wine-dark" to describe the sea in the Iliad and Odyssey so puzzled 19th Century English Prime Minister William Gladstone that he thought the Ancient Greeks must have been colorblind. Since then many other solutions have been proposed. Scientists have argued that Ancient Greek wine was blue and some scholars have put forward the case that Homer was describing the sea at sunset. Radiolab devoted a segment to the exploration of this issue, saying that Gladstone was partly right. Another interpretation is that the Ancient Greeks focused on different aspects of color from us. Classicist William Harris' short essay about purple in Homer and Iliad translator Caroline Alexander's longer essay The Wine-like Sea make the case for this interpretation.

...never believing the people who think they have you figured out.

"It's his charm. It's his gift. It's his political liability, and it's part of an American conundrum. We beg for authenticity, and then when we get it, oh man, it's hilarious. [Vice President Joe] Biden can be fantastic when he's on his game. At the 2012 Democratic National Convention, his speech got higher Nielsen ratings than either Bill Clinton's or Obama's. He killed the debate against Ryan, pumped air back into a campaign deflated after Obama's miserable first performance against Romney. Watching those performances, it's almost impossible to see him as a person once crippled by speech."

Racial Slur or Honorific?

The Other Redskins. 62 US high schools in 22 states currently use the name "Redskins" for one of their sports teams. 28 high schools in 18 states have dropped the mascot over the last 25 years. As public pressure continues to intensify on the Washington Redskins football team to change their name -- one many consider a racial slur that disparages Native Americans -- similar debates are being waged in towns across the country about their local high school teams.

The fall over the last decade has resulted in the UK homicide rate now being roughly equivalent to that of the Western European average, and it is now at its lowest level since 1978. [more inside]

Ein Beitrag zur Optik der Farbanstriche

For years now, the primary way of representing and storing color on a computer display has been to define it as existing in three dimensions: Red, Green, and Blue. What if that's wrong? “While the appearance of a color on a screen can be described in three dimensions, the blending of color actually is happening in a six dimensional space,” How Fifty-Three, developers of the iPad painting app Paper, used a theory of paint optics from 1931 to develop a better color mixer.

A Watched Clock Never Moves

Have you ever wondered why you don't see motion blur when your eyes flick to a new position? Why, if you sit in front of a mirror and watch yourself, you never see your eyes move? That is saccadic masking, one of the lies your brain tells to avoid confusing you. Have you noticed that the first tick after glancing at a clock with a second hand can take more than one second? No, it's not just you! That's a related phenomenon called chronostasis, or more commonly the stopped clock illusion.

What it sounds like

"Kohn" is an award-winning radio story produced by Andy Mills (a graduate of the Salt Institute) that was honored in the 2011 Third Coast/Richard H. Driehaus Foundation Competition. The story, which features the musicians of Hudson Branch/Dogs on Tour, tells what happens when someone hears his own voice for the first time and finds that it's not what he expected. (And a Radiolab short based on the story explains why what we hear in our heads isn't always what the world hears from our mouths.) In a similar vein, another Third Coast winner, Seizure's Lament, tells the story of a radio producer who wanted to know what her seizures look like to other people.

Hello? (((Hello!))) Come to me! (((Me?))) Come, I am here. (((I am here!)))

Whitefield-Madrano is regarding mirrors in the same role that I often give to social media. (Social-media sites seem to me to be self-consciousness machines, encouraging that one maintain a directorial distance from one’s own life experience in order to strategize how to present it in update broadcasts.) But the realities of patriarchy complicate matters considerably; as much as believe we are collectively compelling one another to route our social life through commercial social-media sites, that seems like nothing compared with the coercion involved with fulfilling gendered expectations of self-presentation.
Marginal Utility dissects Mirror Fasting. A goal that blogger Whitefield-Madrano recently took up and called a Month Without Mirrors. The initial reason behind her project: "Sometimes I look in the mirror and see myself, or whatever I understand myself to be. Other times, I distinctly see an image of myself."

The Soul Niche

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it. It all depends how you think it.

THAT'S A BONE

Few phenomena have the power to confound as many different types of people as pareidolia. It doesn't discriminate by culture or religion. It causes Christians to see Jesus and Mary, Muslims to see the names of Allah and the Prophet, Jews to see the Star of David, Hindus to see the monkey-god Hanuman, and Buddhists to see — you guessed it — the Buddha. Even atheists who haven't devoted themselves to skepticism have puzzled long and hard over the famous face, and more recently, Bigfoot, on Mars. Now video has surfaced on YouTube of pseudoscientist and perennial attention-seeker Richard Heene (yes, Balloon Boy's dad) seeing things on the red planet too.

Octarine?

The average human eye has three types of cone cells, each of which is sensitive to a different wavelength range of visible light. The difference in the relative signal from the three cones allows us to distinguish colors. Unfortunately, since these sensitivity ranges overlap, there are some combinations of signals from the cones that can't be created by light emitted from a real object. These are the so-called "imaginary colors". However, by selectively overstimulating one or more types of cone, we can still perceive these colors; this is the principle behind the Eclipse of Titan, an optical illusion which produces both a green and a cyan that don't otherwise appear in nature. (Similar effects can be seen in the Eclipses of Mars, Neptune, and Triton.) [more inside]
