Review of the two articles

In my opinion, the article "Introduction to the Grand Challenges for Engineering" is more important to the profession. At the first of the article the author shows us the achievements of the engineering, which almost reaches everywhere of human life. Thus making me pride of being an engineer. Despite of the accomplishment, engineering still faces great challenges. In the article, the author points out some aspects that are needed to be developed and they all related to engineering. The importance of engineering is obvious. As a future engineer, i think it is important to know the challenges await for me. Then i can think about which aspect i am interested in and want to study in. In the article, the author shows out clearly about many aspects of the challenges and the working targets of engineering. The information is important for me to decide which part is suitable for me. As the author said, the curiosity can be a promotion of engineering. So to make a difference in this field we need to own this spirit. After reading the article i have a better knowledge of engineering. Such as what we have done, what we need to do in the future and how we should do. In this article, there are more details than the article of "The expanding world of engineers" and this article is focus on the challenges that we are facing. I have known more from this article and in my view it is more important for the profession.
