Rewards are limited … physics is everywhere.

Children as young as seven apply basic laws of physics to problem-solving, rather than learning from what has previously been rewarded, suggests new research from the University of Cambridge.

The findings of the study, based on the Aesop’s fable The Crow and the Pitcher, help solve a debate about whether children learning to use tools are genuinely learning about physical causation or are just driven by what action previously led to a treat.

Learning about causality — about the physical rules that govern the world around us — is a crucial part of our cognitive development. From our observations and the outcome of our own actions, we build an idea — a model — of which tools are functional for particular jobs, and which are not.

I wonder if bringing home the money has anything to do with this.

The High Court of Paris on Friday denied Apple’s request for an injunction that would have blocked activist group Attac from protesting at the company’s retail stores across France, as it has been doing for the past several months.

The order states that the mere presence of protesters at Apple’s stores in France, without violence, vandalism, or customers being blocked from entering the premises, is not enough to justify limiting the group’s rights to freedom of expression and freedom of peaceful assembly protected by human rights laws in Europe.

A ‘vision’ problem … When you see exactly what you expect.

No, sexism wasn’t the reason Lawrence was photographed wearing a dress in cold weather.

People were quick to blame sexism for a photo of Jennifer Lawrence that showed her wearing a dress without a coat with a group of men who were wearing coats — and she’s calling the whole controversy offensive and ridiculous.

The idea behind the criticism was basically that Lawrence was somehow forced to go coatless and be freezing because of the patriarchy. …

…. Wow. I don’t really know where to get started on this “Jennifer Lawrence wearing a revealing dress in the cold” controversy. This is not only utterly ridiculous, I am extremely offended. That Versace dress was fabulous, you think I’m going to cover that gorgeous dress up with a coat and a scarf? I was outside for 5 minutes. I would have stood in the snow for that dress because I love fashion and that was my choice.

This is sexist, this is ridiculous, this is not feminism. Over-reacting about everything someone says or does, creating controversy over silly innocuous things such as what I choose to wear or not wear, is not moving us forward. It’s creating silly distractions from real issues. Get a grip people. Everything you see me wear is my choice. And if I want to be cold THATS [sic] MY CHOICE TOO! …

How big could the vocabulary be?

Monkey Vocabulary Decoded

Neuroscientists identify the smallest units that make up the vocalization of marmoset monkeys

From short ‘tsiks’ and ‘ekks’ to drawn-out ‘phees’ — all the sounds produced by marmoset monkeys are made up of individual syllables of fixed length, according to a new study. The smallest units of vocalization and their rhythmic production in the brain of our relatives could also have been a prerequisite of human speech.
