The United States National Academy of Engineering has produced a list of its top twenty engineering achievements of the past century, ranging from electrification to developments in materials science. The basic guideline for inclusion in the list was whether or not an advancement had made a great contribution to the quality of life. (Even devices such as the airplane, invented in the 1800s, were eligible for the list if the judges felt that they had had a great impact on society in the 20th century.)
1. Electrification
2. Automobile
3. Airplane
4. Water supply and Distribution
5. Electronics
6. Radio and Television
7. Mechanised agriculture

You are kidding........ Right?
Look around. Practically everything that you see was designed on a computer system. Anything that's digital (which is just about everything these days) uses engineering technology that simply didn't exist (or could only be afforded on a cost plus contract) 40 years ago.
