为了设计一个建筑，可用软件来模拟设计。换句话说：软件可以辅助对建筑素材的加工。软件能帮助我们试验各种设计的效果，承重强度等。

信息对人脑的改变最终体现在改变了人脑神经网的某部分，如果我们把这个网理解成一个巨大的网状建筑物，人在思维时，是这个网状建筑物发生了某种改变。如果，我们知道想要改变的目标是什么，什么能促进这种改变，那么，我们就有了一个很好的可参照的剧本。

我在 Ted Talk <Taking imagination seriously> 后的 Comments，我谈到了，可以用模拟语义网的变化，来模拟思维的变化。

Janet uses net-format media to visualize something that would otherwise difficult to see: the wind dance can be visualized through the net; the subway running through the dry mist ect.

When we learn, information is encoded and flows into our brain. Our neural network might be a most complicated 'fish-net', continuously changes: dances, makes new connections, shakes, if you see another talk 'I am my connectome', you will know how our brain is like a net.

There is a big potential to use dynamic net format to animate some thinking processes. Learning is about attaching new ideas to the existing fabric/net in our brain. This is like a weaving process: use new threads or new segments to enrich, refine, or/and re-construct the the fabric/net of our brain.

In another Ted talk 'Metaphorically speaking', I think therefore I am is actually: I shake things up, therefore I am. From the neural networks perspective, this is to co-shake neurons storing both the sources and targets. From the semiotics perspective, this is to co-shake words/sentences representing the sources and targets.

It could be difficult to precisely locate and trace the neural activity, but it is possible to locate and trace sign activity with the aid of some externalized net model. I think of another Ted talk about discovering DNA: how chemical models made the difference in their discovery.

Janet, thank you so much for inspiring me! I believe that you and other artists might help learning scientists to figure out a breakthrough way to teach our kids on how to learn and think creatively. So that they can become happy and creative learners.

此外，Tree-nets, Learning Garden 都反映了我 “对学习/思维可视化” 的努力。www.tree-nets.com
