Adler 曾用<a href="https://book.douban.com/subject/34954922/">一本书的篇幅</a>谈如何读书；他将读书这个过程分成了四个层次。但是那本书太长了，我没有完全读下去。尽管如此，我仍有所获，故在此总结一下我所领悟到的读书方法。我愿称之为“渗透式读书法”，或“渐进式读书法”，或“迂回式读书法”。它是一个从“鸟瞰”到“细窥”的过程。</p>

<p>当我们拿到一本书的时候，我们应当仔细阅读其序言、前言、后记等，然后研究其目录，看看每一章的开头和结尾，以获得对这一本书的总体印象。这大概就是 Adler 所谓的第二层之系统性浏览。之后，我们便凭着自己的兴趣点仔细阅读每一章节，甚至每一段落、每一句子、每一词语。这大概就是 Adler 所谓的第三层之分析阅读。</p>

<p>这两个过程中当然都需要做笔记，但我不太喜欢总结中心思想这种行为。一本足够复杂的书不可能只有一个主题、一个观点、一种思想。一本好书应当是你取之不尽的矿藏，它的每一个角落都有可能吸引你的注意。你可以随时针对任何一个段落记录自己的所思，或者记录任何自己想记录的片段。</p>]]></content><author><name>Ladybridge Singers</name></author><category term="Essays" /><category term="book" /><category term="reading" /><summary type="html"><![CDATA[Mortimer J.

<p>然而需要注意“突破”现象，即上轨向上，同时下轨向下的情况。此时可视为市场即将从一个状态跃迁到另一个状态，如果 K 线穿透了上轨，则可将上轨视为支撑线；如果 K 线穿透了下轨，则可将下轨视为阻力线。</p>]]></content><author><name>Ladybridge Singers</name></author><category term="Notes" /><category term="economics" /><category term="finance" /><category term="boll" /><summary type="html"><![CDATA[布林带（BOLL）由金融分析师和交易员 John Bollinger 于 20 世纪 80 年代初创建。它由三条线组成：中轨是均线，上下轨由均线加减两倍的标准差得到。在统计学上，95% 的样本会落在这个区间内，因此布林带的上下轨就指示了一个安全的区间。]]></summary><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://www.ladybridgesingers.org.uk/apple-touch-icon.png" /><media:content medium="image" url="https://www.ladybridgesingers.org.uk/apple-touch-icon.png" xmlns:media="http://search.yahoo.com/mrss/" /></entry><entry><title type="html">Taking Notes While Reading for Better Understanding</title><link href="https://www.ladybridgesingers.org.uk/essays/2021/04/29/taking-notes-while-reading-for-better-understanding.html" rel="alternate" type="text/html" title="Taking Notes While Reading for Better Understanding" /><published>2021-04-29T17:33:00+00:00</published><updated>2021-04-29T17:33:00+00:00</updated><id>https://www.ladybridgesingers.org.uk/essays/2021/04/29/taking-notes-while-reading-for-better-understanding</id><content type="html" xml:base="https://www.ladybridgesingers.org.uk/essays/2021/04/29/taking-notes-while-reading-for-better-understanding.html"><![CDATA[<p>For more than ten years, I have been trying to figure out the best way to read and take notes. Judging from the current situation, I should have failed. My failure is not that I failed to find that method, but that I fell into a kind of obsessive-compulsive disorder in the search, wasting a lot of time, and even ruining my original future. Give up searching! There is no perfect way!</p>

<p>However, there do exist some methods that can be followed to take good notes while reading. An <a href="https://learningcenter.unc.edu/tips-and-tools/taking-notes-while-reading/">article</a> from the <a href="https://learningcenter.unc.edu/">UNC Learning Center</a> gave me great inspiration.</p>

<p>One of key ideas is that we don’t necessary to copy down lots of words from the text, because that won’t engage our brain. This means that the main purpose of taking notes is not to accurately record information, but to better understand the content of the text.</p>

<p>For me, the most useful method mentioned in that article is <strong>to take notes from memory</strong>: read a small section, then leave the book, write down what our read in the memory in our own language; write the main content, don’t have to worry about the details; return to the book after writing, and check to see if there are any omissions or discrepancies. The purpose of this is to force ourselves to think about the content of the book, not to take notes for the sake of taking notes.</p>]]></content><author><name>Ladybridge Singers</name></author><category term="Essays" /><category term="book" /><category term="reading" /><summary type="html"><![CDATA[For more than ten years, I have been trying to figure out the best way to read and take notes.

The website is hosted on <a href="https://pages.github.com/">GitHub Pages</a>.</p>

<p>So, why blog?</p>

<p>The first reason is for note-taking—recording what I read, think, and do. Use words to record my changes over time. Of course, note-taking applications such as EverNote, Notion, etc. can also achieve this purpose. But I hope that my notes are public so that everyone in the world can read them for free and accept their comments. Therefore, a blog is my best choice. In addition, I enjoy writing in plain text. It gives me complete power over the text editing, and there is no “secret” in the plain text—I believe that even after a hundred years, it can still be easily interpreted by people and programs. In this way, I only need a static website generator to convert these plain texts into web pages. Because I am a heavy user of GitHub, and GitHub Pages provides a free hosting service, and Jekyll is the default generator of GitHub Pages, so Jekyll+GitHub Pages has become my first choice.</p>

<p>Besides, if a person needs to leave something after his/her death, I think a blog with rich content is a good legacy, it is the evidence that the person has come to the world.</p>
