This is an illustration that depicts Leonardo da Vinci’s Vitruvian Man. It is famous for showing a man in proper mathematical proportions.

We use measurements and proportion in many aspects of our lives. Artists use proportion to know how to draw the human form:

  • The head and neck are about one-sixth the length of the body.

  • The legs are one-half the length of the body.

  • The upper arm is about equal to the length of the head.

  • The lower arm to the wrist is about equal to the length of the foot.

Measurement conversions are an important part of many occupations, and errors can have disastrous results. Imagine what could happen if you made an error while calculating the amount of fuel that is needed for an airplane. In 1983, this very thing happened in Canada!

Perform an Internet search using the term “Gimli Glider.” In your research, try to find out where the improper use of measurement conversions led to the incident.

Can you find any other similar situations? If you find any other examples, save them in your course folder in case your teacher would like to compile the various examples.
