Thirty-five years after Pi Day was born, the arithmetic group is circling round to ask for extra variety within the subject.
Yearly, NASA and science entities world wide launch math-themed actions to encourage children and adults alike to have fun Pi Day — March 14 (3/14) within the U.S., because the irrational quantity pi begins with the digits 3.14.
There is no lack of math advertising and marketing this 12 months, as NASA’s Jet Propulsion Laboratory launched its annual Pi Day Challenge (opens in new tab) for college students to experiment with math and space, highlighting name-brand missions just like the life-hunting Perseverance rover on Mars and the soon-to-launch Psyche spacecraft concentrating on a steel asteroid.
However with illustration in STEM (science, know-how, engineering and arithmetic) persevering with to lag, latest initiatives are additionally making an attempt to enhance the outlook for future college students by getting them involved in science early, and offering wanted monetary and logistical assist to hold them alongside throughout their post-secondary training.

Circles had been vital to quite a few historic cultures, as evidenced by the Buddhist Dharma wheel, Indigenous sharing circles, Asian mandalas and Stone Age astronomical monuments like Stonehenge. Pi, or the ratio of a circle’s circumference to its diameter, has been recognized about for not less than 4,000 years; circles themselves are key to space science in lots of facets (a number of of which embrace orbits, solar and lunar eclipse calculations or craters on the moon and Mars.)
The traditional Babylonians and Egyptians used pi, although the Greek mathematician Archimedes of Syracuse (287–212 BCE) and Chinese language astronomer Zu Chongzhi (429-501 AD) had been the primary recorded people to calculate pi, in keeping with the Exploratorium (opens in new tab) museum in San Francisco. (The Exploratorium additionally hosted the primary Pi Day celebration in 1988.)
Pi Day at this time is acknowledged each in U.S. and European relationship techniques, though abroad Pi Day falls on what July 22 (22/7 within the day/month system, as 22 divided by 7 approximates pi). Coincidentally, Albert Einstein‘s birthday falls on U.S. Pi Day. Princeton College, the place Einstein famously held a non-faculty workplace for 22 years, holds an annual Einstein lookalike contest (opens in new tab) on Pi Day alongside round celebrations. Pi Day additionally falls throughout Ladies’s Historical past Month, a U.S. celebration lasting via March, and shortly after the United Nations-backed Worldwide Ladies’s Day on March 8.

Pi Day is well known because the International Day of Mathematics (opens in new tab), however the occasion shouldn’t be with out controversy. As feminine mathematician Alissa S. Crans wrote (opens in new tab) in Scientific American in 2022: “There’s a lot extra to math than one solitary quantity, no matter nevertheless many digits you possibly can recite from reminiscence.”
For instance, NASA’s so-called “Hidden Figures” had been Black feminine mathematicians who calculated orbital trajectories within the Sixties that had been key to early space and moon exploration. They’ve been honored publicly simply within the final decade or so; final month, for instance, NASA and the Worldwide Astronomical Union named a prominent moon landmark after Black mathematician Melba Mouton.
With non-male and various illustration nonetheless missing in scientific fields, grassroots efforts have sprung up round Pi Day to remind individuals to prioritize variety in math and science fields. One instance is #DressForSTEM, began in 2016 by feminine meteorologists.
Yearly, this group wears purple to focus on the necessity to convey extra sorts of individuals into science. That is as a result of, in 2019, STEM illustration by girls stood at simply 27% regardless of girls making up 48% of the workforce, the U.S. Census Office (opens in new tab) reported in 2021. (Genders aside from female and male usually are not mentioned within the evaluation.) Black and Hispanic employees stay underrepresented in STEM in addition to different minorities, the Pew Research Center added (opens in new tab) in a publish that very same 12 months.
Glad #PiDay! what which means… #DressForSTEM We’re sporting purple at this time to assist girls within the STEM subject & encourage the subsequent era of ladies to observe their science goals. The sky is the restrict! pic.twitter.com/Yrjr0N0FDaMarch 14, 2022
Growing variety in STEM would require extra illustration in training, significantly on the faculty and college stage, Pew officers added. There are quite a few initiatives underway to extend variety, though they’re fairly latest and should take a long time to bear fruit.
Ohio’s Heart of Science and Trade (COSI) launched a Learning Lunchbox program in 2020, initially aiming to convey meals and science kits to the door of scholars affected by the early pandemic in Columbus, the place half of residents are minority and 20% reside in poverty, in keeping with U.S. Census Bureau 2020-21 statistics (opens in new tab). This system rapidly grew to nationwide after which worldwide realms as soon as it caught the eye of NASA and the Workplace of the Vice President (OVP).

Final September, OVP additionally backed a push by quite a few space corporations (led by Blue Origin, Boeing, Lockheed Martin and Northrop Grumman) to convey extra variety into the space workforce by hiring past the Ivy League and legacy top-tier engineering faculties. Sources embrace Traditionally Black Schools and Universities, Tribal Schools and Universities, minority servicing establishments, group schools and commerce/vocational faculties, White Home officers stated on the time.
In recognition of varied obstacles to variety, NASA has adopted a diversity and inclusion approach (opens in new tab) together with quite a few different space and science-themed organizations world wide. Those that are keen about math can simply perceive the statistics exhibiting underrepresentation.
NASA will get that, too, company chief Invoice Nelson stated throughout his annual State of NASA address (opens in new tab) final week. “We additionally perceive that variety drives innovation, and we’re dedicated to strengthening our company by prioritizing variety, fairness, inclusion and accessibility,” he stated throughout the speech on Friday (March 10).
The company is together with this focus in its strategic plans, Nelson famous, particularly because it plans out its Artemis 2 crewed moon-circling mission in 2024 and different missions of the Artemis program. Saying that NASA’s workforce ought to replicate the inhabitants of the U.S., Nelson stated the company will “proceed making historical past and enabling the Artemis era to make this vital work its personal.”
