CHARCHA2013 : Science, ,Applied Science , Technology and Engineering

I can think of Sri GD Naidu An inventor .But notwith much education. He is perhaps a technologist sarma

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?

Regards/Suresh
