The Beauty of Mathematics was originally a series of articles serialized on Google Blackboard, the official blog of Google China, from 2006. Wu Jun, a senior member of Google, was invited by Ms. Wu Dandan, a former blackboard editor, to write something about Google technology on Google Blackboard, so Wu Jun wrote a series of short articles based on his research experience at Google at that time and at Johns Hopkins University before, introducing the basic technology behind Google products, especially the mathematical principles. After several articles were published, they attracted the attention and love of employees and college students in the IT industry, and were reprinted tens of thousands of times on the Internet with millions of readers. As a result, Wu Jun wrote more than 20 articles one after another. Later, due to constant changes in work, writing was interrupted. In the meantime, readers continue to pay attention to this series, hoping that this series may be published again. Therefore, starting from 20 10, Wu Jun successively completed the last articles in this series and began to revise them into books.
