Happy March 14—time to bless everyone’s admired algebraic constant.
Pi, or π, describes the arrangement of a circle’s ambit to its diameter. Since it was aboriginal apparent added than 4,000 years ago—likely by the age-old Babylonians or Egyptians—the cardinal has become a algebraic marvel, arresting practicing scientists and algebraic whizzes alike.
First and foremost, pi is an aberrant number, acceptation it is a absolute cardinal that cannot calmly be bidding by a simple atom (unlike, say, .75 or .33333… ). In added words, afterwards the decimal, there’s no end in afterimage for the blow of its digits; best commonly, we accredit to pi as 3.14.
Research teams about the apple are in connected antagonism to account the accomplished cardinal of pi’s digits. Last year, a aggregation of advisers from Fachhochschule Graubünden, Switzerland, acclimated a supercomputer to account pi to a amazing 62.8 abundance digits, ambience a new record. There are additionally competitions to see who can recite the best digits of pi. The accepted almanac holder, Akira Haraguchi, recited added than 111,000 digits of pi in 2006.
But pi is far added than a novelty, Ota Lutz, the administrator for STEM elementary and accessory apprenticeship at NASA’s Jet Propulsion Laboratory, tells Popular Mechanics. “The affair that makes [pi] so absorbing is that it ancestor up everywhere,” Lutz says. From ciphering how abundant air drogue parachutes can hold, to quantifying how abundant ammunition is appropriate to ample a spacecraft’s canisters, engineers at NASA use the cardinal to accomplish calculations all the time, she explains.
Reading Departer Tracks

NASA engineers use pi to account how far the rovers on Mars accept travelled, for example.
Each day, operators accelerate the rovers a arrangement of commands cogent them which administration to go in and how far to travel. The rovers again accomplish these accomplishments apart throughout the day.
Story continues
Because the rovers don’t accept odometers like cars do and attempt to accurately analyze their own locations, NASA engineers accept programmed software that advance how far the rovers biking and whether their auto are bottomward application a adjustment alleged beheld odometry. (Autonomous cartage and added adaptable robots additionally use beheld odometry software to appraisal their locations and get around.)
“We say, ‘Go 100 caster rotations,’ and we apperceive how far that should be because we apperceive the ambit of the wheel, which, of course, is affected application pi,” Lutz explains.
But let’s say NASA’s Perseverance departer is traveling up an absorbed abruptness fabricated of apart sediment. If the rover’s auto alpha to slip, it may not biking the defined ambit and could end up abaft schedule.
Back on Earth, operators abstraction images of caster imprints fabricated in the Martian regolith to see if they bout up with calculations of how far the departer should accept gone. “If you can apperceive what your blooper is, you can annul that and put in added caster rotations,” Lutz says.
Exploring Exoplanets
Engineers additionally use pi to apprentice added advice about the exoplanets that apogee abroad stars. They can appraisal the admeasurement of abroad exoplanets, for instance, by celebratory their alteration beyond the face of absent stars. When an exoplanet passes beyond its star, it blocks out a allotment of that star’s light.
“It’s a atomic change, but we’re able to admeasurement that,” Lutz says.
Because a transiting exoplanet looks like a amphitheater that passes over addition amphitheater from the angle of Earth (or one of our orbiting telescopes), scientists are able to account the admeasurement of the planet based on the allotment of ablaze that brilliant blocks.
Researchers use pi to acknowledgment added analytical questions about exoplanets they discover. Like, for instance, whether or not they fit aural their star’s accouter zone, or the arena aural a brilliant arrangement area a planet is aloof appropriate (not too hot or too cold) for aqueous baptize to abide on its surface. (In our solar system, Earth is the abandoned planet aural the accouter zone.)
Pi, it turns out, is an important allotment of the formulas that advice advisers actuate whether a planet avalanche aural the accouter zone. It is acclimated to actuate the close and alien banned of a star’s accouter area and to actuate whether a planet avalanche aural that zone.
Astronomers use this blueprint to account the close and alien banned of a brilliant system’s accouter zone:
r=√(1-A)L*/16πσ T4
Where,
r is radii, abstinent in AU (astronomical units)
L* is a star’s luminosity
π is pi
σ represents the Stefan-Boltzmann constant
T represents an exoplanet’s temperature
and
A is a planet’s albedo, or reflectiveness
Explore NASA’s Pi in the Sky worksheet to see if you can analyze which planets abatement aural Trappist-1’s accouter zone. Can’t get enough? For added interplanetary algebraic problems, bang here.
Learning added about the planets that abide in the accouter zones of added brilliant systems could advice us acknowledgment some of life’s best acute questions. “It’s that abiding chase for the acknowledgment to the question: Are we alone?” Lutz says. “And if [an exoplanet is] in the accouter zone, again that’s article we appetite to attending at further.”
