Describe a book you read that you find useful
You should say:
What the it was about
How you got to know about it
How often you read it
And explain why it is useful to you

One of the useful books I read recently is An Introduction to Mathematical Modeling’ written by Edwards. This book was recommended by my professor David, and I read it a few times last year. The book introduces various mathematical modeling methods and shows examples of how those methods are applied in business, science, and engineering.

This book is instrumental for me, as it develops my interest in mathematical modeling. I find it interesting and useful for several reasons. Firstly, mathematics models have incredible power and beauty; and it is the key to innovations in most science, technology; engineering, and mathematics-related fields. Secondly, it helps us to manipulate the world around us. To solve modeling problems, we can make assumptions, choose mathematical approaches, and assess the solution for usefulness and accuracy. Then we can rework and adjust the model until it provides an accurate and predictive result of the situation. That’s really fantastic.

Besides, it deepens my understanding of many mathematical concepts, such as statistics and equations, as I studied mathematics without understanding how to apply it in real life. Although I found it isn’t easy at the beginning as I had to understand the complex mathematical concepts and methods, after reading it repeatedly and doing some research, I know modeling quite well now.

故事简介：我最近读到的一本有用的书是爱德华兹写的《数学建模入门》。这本书是我的教授大卫推荐的，去年我读 了好几遍。这本书介绍了各种数学建模方法，并展示了这些方法如何应用于商业、科学和工程的例子。

这本书对我 来说是工具性的，因为它发展了我对数学建模的兴趣。我发现它有趣和有用的原因有几个。首先，数学模型具有不 可思议的力量和美丽，它是大多数科学、技术、工程和数学相关领域创新的关键。其次，它帮助我们操纵我们周围 的世界。为了解决建模问题，我们可以做出假设，选择数学方法，并评估解决方案的有效性和准确性。然后我们可以重新工作和调整模型，直到它提供了一个准确的预测结果的情况。这真的是太棒了。

此外，它加深了我对很多数 学概念的理解，比如统计和方程，因为我以前学习数学的时候并不了解它在现实生活中的应用。虽然一开始我发现 它很难理解复杂的数学概念和方法，但经过反复阅读和研究，我现在对建模有了很好的了解。
