CHARCHA2013 : Science, ,Applied Science , Technology and Engineering

Dear All:

I thank Prof. Sarma for initiating the topic. I am attaching some reading material (three popular science/engineering articles and four editorials) that I had published in Resonance: Science Education Journal of Indian Academy of Science.

I chose the articles because there are at least two engineers interested in structures (other than me) in our group.

The point of discussion is: what makes someone a great engineer?

Some sub-questions are: what distinguishes a scientist and an engineer? What’s the difference between engineering and technology? Where do the inventors lie in the continuous spectrum of science-engineer-technologist?
