Usually the students thought that this aspect of physics, in particular, and science, in general, is not important. However, it is not the same mistakes in an exercise on paper than on a real problem of engineering or science.
To give a value to this entry, we attached some news and the causes of the accidents that have occurred for reasons that should never happen.
- The NASA’s mission Mars Climate Orbiter (September 1999), had a part of the engineering team working in English units (feet, inches and pounds) and another one working in the decimal metric system. Incredible but true and below are some links for verification:
