Today, NASA is inviting the public to celebrate Pi Day by sharing a series of cosmic calculations for kids and adults to solve.
The “Pi in the Sky” challenge was created by the Education Office of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, and is now in its fifth year. The challenge will feature math problems to calculate for Martian earthquakes, helium rain on Jupiter and the rotation rate of the first interstellar visitor ever discovered, asteroid ‘Oumuamua. The topics of last year’s Pi Day challenge included craters with butterfly-shaped ejecta, or tossed material, and the total solar eclipse.
Pi is a number whose digits go on forever, but it’s most popularly known by the first three: 3.14 (hence March 14). It is a mathematical constant often denoted by the symbol π. Pi comes in handy when determining the circumference or the surface area of a round celestial body. It also helps engineers and scientists program the precise orbits of satellites and spacecraft. such as the impressive pirouettes the Cassini spacecraft performed before its “death dive.
Ota Lutz, a senior education specialist at JPL, believes everyone should attempt the Pi Day Challenge, even if they aren’t familiar with these math tools. Students in grades 5 through 12 are especially invited to participate, and JPL offers resources for educators who want to use the math problems in their classrooms.
“All of the problems in the ‘Pi in the Sky’ challenge are real problems that JPL scientists and engineers solve using pi,” Lutz said in a statement.
Solutions to the illustrated questions will be posted on March 15, according to NASA. Pi Daychallenge problems from
