Learning

听到他们这么讲，我说，那你们为何不给他们一对一的辅导呢？他们说，”我们每个人都在五个班任教，每个班的学生人数为30到40，这样加起来就有近200 名的学生。你想想看，我们甚至连给予每位学生一周一个小时的指导都做不到呢！“要想真的这么做，你就得延长工作时间或增加教师的数量。我于是跟他们细细的 商量这样的事情，此时我想起了我认识的生活在这里的作家、编辑、记者、研究生、助理教授等人士，他们大都有一个灵活的工作时间，并且对于英语语言本身具有 浓厚的兴趣。他们都知道一种良好的语言表达对于民主的培育、智慧人生的塑造的重要意义。他们有的是时间和对于语言的兴趣，可是当时在我的社区里却没有一种 良好的方式能够让他们和那些亟需指导的学生之间搭起桥梁。

"The hippocampus is crucial for navigation and we use it like a 'sat nav'," says Dr Spiers from the Institute of Behavioural Neuroscience at UCL. "London taxi drivers, who have to know their way around hundreds of thousands of winding streets, have the most refined and powerful innate sat navs, strengthened over years of experience."

Human free will might seem like the squishiest of philosophical subjects, way beyond the realm of mathematical demonstration. But two highly regarded Princeton mathematicians, John Conway and Simon Kochen, claim to have proven that if humans have even the tiniest amount of free will, then atoms themselves must also behave unpredictably.

“If the atoms never swerve so as to originate some new movement that will snap the bonds of fate, the everlasting sequence of cause and effect—what is the source of the free will possessed by living things throughout the earth?”—Titus Lucretius Carus, Roman philosopher and poet, 99–55 BC.

Rapid advances in neuroscience could have a dramatic impact on national security and the way in which future wars are fought, US intelligence officials have been told.

However, contact between nerve cells is also constantly being set up and dismantled in adults. It is this continuous restructuring of the brain that allows us to learn and to forget.

In reality, it should actually be consuming much more energy. This is because both young and adult nerve cells allow many hundreds of cell extensions to grow towards their neighbours.

In this light, it’s not surprising that people behave less morally as they become skeptical of free will. Further, the Vohs and Schooler result fits with the idea that people will behave less responsibly if they regard their actions as beyond their control. If I think that there’s no point in trying to be good, then I’m less likely to try.

For a long time, we were pretty dumb. Humans did little but make "the same very boring stone tools for almost 2 million years," he said. Then, only about 150,000 years ago, a different type of spurt happened — our big brains suddenly got smart. We started innovating. We tried different materials, such as bone, and invented many new tools, including needles for beadwork. Responding to, presumably, our first abstract thoughts, we started creating art and maybe even religion.
