STEM Careers Coalition: It’s a Small World
If all the people in the world moved to New Zealand, how crowded would it be?

Explore the science behind community planning by imagining the potential a limited space has to support a large population.

Fermi problems require you to make a quick estimate of
a quantity that seems difficult or impossible to determine
precisely. They were named after Enrico Fermi, the Italian
physicist who used this problem solving method to predict how
atoms would work long before scientists had the technology to
actually see atoms. Fermi problems emphasize the process of
solving problems over getting the exact answer.
