 <title>mindmap 脑图</title>
 <link>http://gezhi.org/node/903</link>
 <description>&lt;p&gt;在脑图（MIND MAPS）发明人托尼巴赞（Tony Buzan）的网站上，对脑图是这样定义的：&lt;/p&gt;
&lt;p&gt;A Mind Map is a powerful graphic technique which provides a universal key to unlock the potential of the brain. It harnesses the full range of cortical skills–word, image, number, logic, rhythm, colour and spatial awareness–in a single, uniquely powerful manner. In so doing, it gives you the freedom to roam the infinite expanses of your brain. The Mind Map can be applied to every aspect of life where improved learning and clearer thinking will enhance human performance.&lt;/p&gt;
&lt;p&gt;Originated in the late 1960s by Tony Buzan Mind Maps are now used by millions of people around the world – from the very young to the very old – whenever they wish to use their minds more effectively.&lt;/p&gt;
&lt;p&gt;Similarly to a road map, a Mind Map will:&lt;/p&gt;
&lt;p&gt;Give you an overview of a large subject/area.&lt;br /&gt;
Enable you to plan routes/make choices and let you know where you are going and where you have been.&lt;br /&gt;
Gather and hold large amounts of data for you.&lt;br /&gt;
Encourage problem solving by showing you new creative pathways.&lt;br /&gt;
Enable you to be extremely efficient.&lt;br /&gt;
Be enjoyable to look at, read, muse over and remember.&lt;br /&gt;
Attract and hold your eye/brain.&lt;br /&gt;
Let you see the whole picture and the details at the same time.&lt;br /&gt;
Assist YOU!&lt;/p&gt;
&lt;p&gt;大意是：脑图是一个打开大脑潜能的强有力的图解工具。它同时运用大脑皮层的所有智能，包括词汇，图像，数字，逻辑，韵律，颜色和空间感知。 它可以运用于生活的各个层面，帮助你更有效地学习，更清晰地思维，让你的大脑最佳表现。&lt;/p&gt;
&lt;p&gt;脑图由Tony Buzan在六十年代创立。至今，在全球已经为成千上万的人使用。从小孩到老人，只要你想更有效地使用你的大脑， 你就可以使用脑图。&lt;/p&gt;

 <description>&lt;p&gt;用数学作图来证明一些数学命题起源于古代的中国，阿拉伯，希腊和印度，但真正引起大家感兴趣却是在最近三十年左右的事情。这就是所谓的 proof without  words，意思是不用文字或者尽量少地借助于文字说明，直接用图来证明一些数学结果。&lt;/p&gt;
&lt;p&gt;在 Mathematics Magazine, The College Mathematics Journal 等数学教育杂志和互联网上现在已经有成百上千的proofs without words出现。这个领域影响比较大的有美国俄勒冈(Oregon)州的 Lewis &amp;amp; Clark College的 Roger B. Nelsen等人&lt;br /&gt;
http://www.lclark.edu/~mathsci/nelsen.html&lt;/p&gt;
&lt;p&gt;在格致中有 http://gezhi.org/ipang 等人也涉猎这个领域。&lt;/p&gt;
&lt;p&gt;我是一名数学教师，希望我的同行或者对数学有兴趣的其他朋友多交流。&lt;/p&gt;
