Our brains don't work.

Friday, May 22, 2009

Friday night links of variable goofiness.

* Ze Frank has your optical illusion of the night.

* Lateral thinking interview questions from Microsoft.

You have two jars, 50 red marbles and 50 blue marbles. A jar will be picked at random, and then a marble will be picked from the jar. Placing all of the marbles in the jars, how can you maximize the chances of a red marble being picked? What are the exact odds of getting a red marble using your scheme?
* My friend Jay explains the story behind his possession of the world's most badass scar.

* Who ate all the Neanderthals? Oops.

* Which of our own closely held beliefs will our own children and grandchildren by appalled by?

* Also: classic sci-fi box office adjusted for inflation.

* Jacob directs our attention to the growing threat of Transforminators.

* Bo Obama, Dog Superhero.

* Wes Anderson, the YouTube Channel.

Failure to "see" the concave face optical-illusion is apparently an indicator for schizophrenia.

Dima and Jonathan Roiser of University College London wanted to understand why people with schizophrenia aren't fooled. They put 13 schizophrenia patients and 16 healthy control subjects in an fMRI scanner that measures brain activity, and showed them 3D images of concave or convex faces. As expected, all of the schizophrenic patients reported seeing the concave faces, while none of the control subjects did.

#2: culture!

* How HBO changed TV.

* Is Sarah Connor canceled?

* Europe names crew for simulated mission to Mars. Devotees may remember that this is strikingly reminiscent of the first episode of The Twilight Zone.

* Examined Life is your crash course in contemporary philosophy.

I'm not suggesting that Taylor set out to sandbag or ironize her subjects in "Examined Life." In fact, I'm quite sure she didn't. But as with Taylor's previous film, "Zizek!" (whose subject, the Slovenian madman Slavoj Zizek, appears here at a London garbage dump, claiming that mankind isn't alienated enough from the natural world), the movie has a philosophical element of its own that is not free of guile. By conducting her conversations in public spaces, and removing her interlocutors from desks and offices and book-lined studies and other appurtenances of intellectual authority, Taylor introduces a degree of playfulness and unpredictability that becomes the movie's M.O. Trying to rehabilitate the concept of revolution while rowing in the Central Park lake, post-Marxist philosopher Michael Hardt literally runs aground on a half-submerged boulder. I'm far more sympathetic to Hardt's intellectual project than I should admit, but, really, what can you say?
* The great American novel v. women. (Or maybe that's the other way around.)

* Alan Moore v. comic book films. More Moore here and here.

* How they marketed Watchmen: a look back at the original solicits from 1986.

* Gary Westfahl: Why Science Fiction So Often Fails to Predict the Future. Another thing Suvin makes clear in his very good book on science fiction is that if you're expecting science fiction to predict the future you're asking the wrong questions.

* The Indy just announced the winners of their 2009 poetry contest, and once again Jaimee was one of the judges.

* And Neil sends along some optical illusion fun.

Respecting my long-standing fascination with optical illusion, Neil sends along the Pink Dots Illusion.

If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink.

However if you stare at the black '+ ' in the centre, the moving dot turns to green.

Now, concentrate on the black ' + ' in the centre of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

The key to all optical illusions discovered, and it's simple: Humans can see into the future.

Changizi now says it's our visual system that has evolved to compensate for neural delays, generating images of what will occur one-tenth of a second into the future. That foresight keeps our view of the world in the present. It gives you enough heads up to catch a fly ball (instead of getting socked in the face) and maneuver smoothly through a crowd. His research on this topic is detailed in the May/June issue of the journal Cognitive Science.
