The Metre Zone is a General Engineering Zone, where we will meet five engineers from five different areas of engineering. Engineers are more than Structural Engineers or Mechanical, more than Electrical Engineers or Civil; engineers aren’t defined by just one field. This zone will demonstrate the breadth of engineering as a discipline.
The Metre Zone is named for the SI base unit for length, metre, m. The metre was defined in 1793 as one ten-millionth of the distance from the equator to the North Pole.
In the Metre Zone there are engineers building nuclear reactors, designing new underground stations in London, and trying to improve medical care in diseases such as cancer and aging. There are also engineers designing new parts for fold-up bicycles, and using electronics, software and hardware to design networks that help control traffic!
