NASA Pi Day Challenge: Celebrate the Mathematical Marvel With Stellar Math Problems

Pi Number and Symbol

Pi Day is an annual celebration commemorating the mathematical constant π (pi). It is observed on March 14th (3/14) since the first three digits of pi are 3.14. Pi Day was first officially recognized by the US House of Representatives in 2009, and has since been celebrated by math enthusiasts, educators, and students around the world.

Pi Day is a day for people to celebrate and appreciate the importance of pi in our lives, and is often marked by various events and activities such as pie-eating contests, pi recitation competitions, and lectures on the history and significance of pi. Some people also use Pi Day as an opportunity to raise awareness about the importance of math and science education.

NASA’s Jet Propulsion Laboratory celebrates the mathematical marvel with a set of problems involving real space missions.

Pi Day is the annual tribute to the mathematical constant pi, whose infinite number of decimals is usually rounded to 3.14. So what better day to celebrate than March 14? To find pi, aka the Greek letter p, you simply divide any circle’s circumference by its diameter. It’s a ratio that’s indispensable to NASA missions studying Earth, Mars, and beyond.

This Pi Day marks the 10th year that the Education Office at NASA’s Jet Propulsion Laboratory has celebrated this wondrously useful number with the agency’s Pi Day Challenge. Students can put their math mettle to the test to solve real problems faced by NASA scientists and engineers.

Using pi to tackle this quartet of problems, students can:

Answers to all four challenge questions will be available on March 15.

The NASA Pi Day Challenge is accompanied by other pi-related resources for educators, K-12 students, and parents, including lessons and teachable moments, articles, downloadable posters, and illustrated web/mobile backgrounds. More than 30 puzzlers from previous challenges are also available.

Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is a non-repeating and non-terminating number that has been calculated to trillions of digits, but is commonly approximated to 3.14. Pi is used in many fields, including mathematics, physics, engineering, and statistics, and has numerous applications in everyday life such as in the design of buildings, the calculation of distances in navigation, and in the measurement of circles and spheres.
