    "The German polymath Johann Wolfgang von Goethe considered his monumental book known in English as The Theory of Colours to be his greatest achievement. The book is a record of hundreds of Goethe's observations about the way colour affects our mood, as well as a long and heated polemic with Isaac Newton's colour theory. Goethe's understanding of light and colour was scientifically flawed yet his book had a surprisingly strong influence on the fine and applied arts. To find out why, Bridget Kendall talks to art historian Alexandra Loske, colour writer Victoria Finlay and designer Odette Steele."

    "Living for two years in Paris changed Vincent van Gogh. He might not have realised it at the time, but as he met other artists in the French capital, he gradually moved away from his dark, sombre Dutch works - towards much brighter palettes and expressive brush work."

  • "Time" is something that both philosophers and physicists have been wondering for about, well, a long time. And now, the neuroscientists have joined in. They have found a man who, when he looks at you, hears what you are saying to him before your lips move.
  • We don't notice this delay in reality because we have evolved to be able to deal with this. We can anticipate actions or patterns through experience.
  • Now you might not realise this, but in terms of vision you are always living 0.3 second (or 300 milliseconds) behind reality. That's how long it takes between when the incoming light lands on the cells in your retina, and you get that full magnificent wraparound 3D colour sensation that we call vision.

  • So how come we normally see the lips moving at the same time as we hear the voice? Almost certainly, it's because our brain deliberately inserts a delay of about 200 milliseconds on the audio circuit. Now sure, there would be an advantage in being able to hear dangerous things, such as the killer kangaroo bearing down upon you that extra 200 milliseconds earlier. But all of us are a product of an evolutionary pathway that decided it was more important for us to be able to easily communicate with our fellow humans, than to hear the killer kangaroo that 200 milliseconds sooner. After all, we humans are quite pathetic as a hunting animal. We can't run very quickly, our eyes are not very sharp, and neither is our sense of smell. Our claws are silly little fingernails, and our teeth are not very good at ripping and tearing. But thanks to our amazing brain, we can organise ourselves into groups and so we have become masters of the planet. So, getting back to Mr PH, if the sound of the outside world was deliberately electronically delayed by 200 milliseconds, suddenly audio and vision were in sync for him again. And when the neuroscientists did an MRI scan on his brain, they found damage in areas that were well-placed to disrupt audition and/or timing.

language history

shared by Lawrence Hrubes on 08 Jun 15 - No Cached
  • First, the greed: invasion and theft. The Romans invaded Britain in the 1st Century AD and brought their alphabet; in the 7th Century, the Angles and Saxons took over, along with their language. Starting in the 9th Century, Vikings occupied parts of England and brought some words (including they, displacing the Old English hie). Then the Norman French conquered in 1066 – and replaced much of the vocabulary with French, including words which over time became beef, pork, invade, tongue and person.
  • Once the English tossed out the French (but not their words) a few centuries later, they started to acquire territories around the world – America, Australia, Africa, India. With each new colony, Britain acquired words: hickory, budgerigar, zebra, bungalow. The British also did business with everyone else and took words as they went – something we call “borrowing,” even though the words were kept. Our language is a museum of conquests.
  • Sometimes sounds just change capriciously. The most significant instance of this in English was the Great Vowel Shift. From the 1400s to about 1700, for reasons that remain unclear, our long vowels all shifted in our mouths like cream swirling slowly in a cup of tea. Before it, see rhymed with "eh"; boot was said like “boat”; and out sounded like “oot.” But when the sounds shifted, the spelling stayed behind.
  • ...1 more annotation...
  • One more layer of snobbery has added further complications across the Atlantic over the last couple of centuries: national pride. The (relatively few) American simplifications of spelling – color for colour, center for centre – largely owe their existence to Noah Webster’s desire to create a distinctive American English. Canadian preference for keeping many British spellings, on the other hand, has the same nationalistic origins… just in reverse.And now? Now we don’t even want to spell things as they sound. How do spellings like hed, hart, lafter, dotter, and det look to you? Uneducated, perhaps? Annoyingly simplistic? Exactly. We enjoy our discomforts – and we really enjoy arbitrary practices that allow us to tell who are and aren’t the “right sort”. We’ve taken a useful tool and turned it into a social filter.

    So what does this say about any eyewitness testimony that could convict them by placing a suspect at the scene of a crime based on the colour of what they are wearing? Why is that not being brought up in any of the discussions, I wonder?

ethics language racism antisemitism identity

shared by Lawrence Hrubes on 08 Mar 15 - No Cached
  • Thankfully, most of this Jew-targeted hatred takes the form of verbal aggression rather than physical violence. But because many critics of Israel make no distinction between citizens of the Jewish state and the worldwide Jewish community, the J-word has been the focus. You won't see "Kill Israelis" scrawled on London synagogue walls. What you see on walls is "Kill the Jews", and on banners "Hitler was Right". And this brings me back to the point about the complexity of anti-Semitism today. It is always around and in the end it is focused primarily on the J-word, in the same way that another form of racism is focused on the N-word. Those on the receiving end find their lives shaped by it. Certainly my life, my sense of myself, has been shaped by the casual anti-Semitism that I have encountered for more than half a century. The first time I was called a "Jew" with malicious intent was September 1958 in the playground of Belmont Hills Elementary School, in the suburbs of Philadelphia. It came as a surprise. I was eight years old and up until that time had been living in New York City where everyone I encountered was Jewish. Until that moment, the word "Jew" had simply been one of the words and phrases - like "Mike", "son" and "114 East 90th Street" - whose meanings were slowly building up into a sense of who I was.
  • Throughout the 19th Century, "Israelite" or "Hebrew" or "follower of Moses" supplanted "Jew" as the politically correct way to refer to the community. It was a process analogous to the way "black" and then "African-American" or "person of colour" replaced "Negro" in polite discourse after the Civil Rights era.
  • Thirty years later, a new word for this hatred was coined - "anti-Semitism". This was a time when race science was all the rage. Anti-Semitism avoided the connotation of pure hatred against individuals which is, after all, irrational. It focused scientifically on the supposed racial and social characteristics of a group, the Jews, without mentioning them by name. From there it was easy to start a political movement - based on scientific "facts" - to rein in a people who clearly were alien.

  • “Adjectives in English absolutely have to be in this order: opinion-size-age-shape-colour-origin-material-purpose Noun. So you can have a lovely little old rectangular green French silver whittling knife. But if you mess with that word order in the slightest you’ll sound like a maniac. It’s an odd thing that every English speaker uses that list, but almost none of us could write it out.”
  • You are utterly familiar with the rule of ablaut reduplication. You’ve been using it all your life. It’s just that you’ve never heard of it. But if somebody said the words zag-zig, or ‘cross-criss you would know, deep down in your loins, that they were breaking a sacred rule of language.
  • It’s astonishing quite how expert you are at the English language. There are so many tenses you can use without even thinking about it, and almost certainly without being able to name them. It depends how you count them, but there are about 20 that you deploy faultlessly.
