Describe a science subject that you are interested in
You should say:
What it is
How you study it
How difficult it is to study it
And explain why you are interested in it

Mathematical modeling is the subject in which I am interested. 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.

I study mathematical modeling in two ways, including reading books and using modeling software. Firstly, I read a great book, which 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 is instrumental as it introduces various mathematical modeling methods and shows examples of how those methods are applied in business, science, and engineering. Besides, I also use computer software such as Matlab to simulate some business problems with models.

I found ifs quite difficult at the beginning as I had to understand the complex mathematical concepts and methods. However; after reading it repeatedly and doing some research, I understand modelling quite well now.

故事简介:数学建模是我感兴趣的科目。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。

我通过阅读书籍和使用建模软件两种方式来学习数学建模。 首先,我读了一本很棒的书,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。这本书非常有用,因为它介绍了各种数学建模方法,并展示了如何在商业、科学和工程中应用这些方法的例子。

除此之外,我还使用Matlab等计算机软件用模型模拟一些商业问题。一开始我发现很难,因为我必须理解复杂的 数学概念和方法。但是经过反复的阅读和研究,我现在对建模有了很好的理解。
