Respons for the two articles

These two articles have different types of readers. The second one, titled "The expanding world of engineers" aim to tell people who are not familiar with engineering what exactly engineering is nowadays. The writer, Prof. Seeram Tamakishma focuses on the development of engineering from taditional design and manufacturing to recent broadened sevice-oriented economy. The professor wants to convince people the important role engineering plays in industry. The first article, however, is more professional. From its title"Introduction to the Grand Challenges for Engineering" it's bovious to see the main topic------what is the direction engineering will go. The author specifies the future aspects of engineering research, including the new energy usage, environmental problem improvement, medical and construction, countreing to the violence of terrorists, effective communication and so on. Besides, the author also tells us the possible difficulties or barriers engineers may meet. In my opinion, the second article is more importatnt to the professions for it shows the research area engineering can go and the hidden barriers of engineering. Therefore, professions can not only choose their proper topic of research but also think more about it to make their fruitful result come into life.
