honor of Pi Day, March 14 (or 3.14), 2013, the Education Office at NASA's Jet Propulsion
Laboratory in Pasadena, Calif., has released an infographic highlighting
some of the ways scientists and engineers at the laboratory use pi in
their daily work. For example, scientists can use pi (along with mass
and radius) to calculate the density of an asteroid and its material makeup.
The infographic also features a pi- and planetary-themed mathematics
challenge for students that asks them to find various measurements for a
fictional "Planet Pi," which appropriately has a circumference of
The infographic is available on the JPL Infographics website and as a full-resolution download (for printing or displays) below.
